hi ther i wonder if you could help me on this simple task. I'm creating a GPS application to run on the XDA2, i'm using eVC++ to do the implementation.
at the moment i'm reading the GPS signal via bluetooth over a virtual COM port, the signal coming from the GPS if a ASCII sinal and i'm duimping this into a char buffer.
However i need to convert this to UNICODE in order to display it on the Pocket PC, how's best to convert a buffer full of ASCII into Unicode so i may display it?
I tried using MultiByteToWideChar(), but it doesn't seem to work properly, maybe i haven't set it up correctly? Could someone point me in the right direction!
Below is an example of what i tried:
Code:
char buf[50]; // contains output from GPS
TCHAR Message[50]; //where i intended to put the message so i could display it
MultiByteToWideChar(CP_ACP, MB_PRECOMPOSED, buf, -1, Message, 0);
Thank in advance
I'm sure it's not the right way to go about it, but I generally wsprintf for short strings.
However, don't listen to me, I'm a mad man. Check this page out instead:

Thanks for that, out of curiosity, how would you use wsprintf to convert ASCII to unicode, i tried that before with no real success!
The last value passed to MultiByteToWideChar tells this function the size of the result buffer, Message in your case. You have passed zero, all that does is makes the function return the size of a TCHAR variable it needs to put the Ascii input buf into.
You need to put sizeof(Message) as the last parameter and not zero.
The other way (better way ?) of doing this is first you call the MultiByteToWideChar function with the zero parameter as you have and then you malloc the result * sizeof(TCHAR).
Thanks for the advise, after looking into the function more i realised this is where i was going wrong, and i have now managed to make the conversion. Thanks for pointing that out though!
Hi Guys:
I'm having a weird problem with TAPI, basically I'm developing an app that intercepts incoming calls and then extract the callerid before starting recording the call.
I'm using WM 2005 and the device is an HTC Universal (T-Mobile MDA PRO) with a T-Mobile UK SIM.
All seems to work fine, the event loop receive the message(s) ,first receives an LINE_APPNEWCALL and then LINE_CALLINFO with dwParam1 set to LINECALLINFOSTATE_CALLERID, but when calling lineGetCallinfo to get the CallerID , the callerid flags (dwCallerIDFlags) returns 32 or "Unknow", even when the built-in alert in the phone is showing the caller id!
I killed cprog.exe from the process viewer (the phone didn't rang so the process was in fact killed) but not difference...Any ideas? Any tricks? Below a copy of the loop that I'm using:
void FAR PASCAL lineCallbackFunc(
DWORD hDevice,
DWORD dwMsg,
DWORD dwCallBackInstance,
DWORD dwParam1,
DWORD dwParam2,
DWORD dwParam3)
{
DWORD dwT = dwMsg;
LINECALLINFO *lpCallInfo;
size_t ci_size = sizeof(LINECALLINFO);
TCHAR *buffNum;
long Err;
OutputDebugString(_T("CB\n"));
switch (dwMsg){
case LINE_CALLINFO: {
switch(dwParam1)
{
case LINECALLINFOSTATE_CALLEDID:
{
OutputDebugString(_T("CALLID"));
break;
}
case LINECALLINFOSTATE_CALLERID:
{
OutputDebugString(_T("CALLERID"));
lpCallInfo = (LINECALLINFO *)calloc(ci_size,1);
lpCallInfo->dwTotalSize = ci_size;
Err = lineGetCallInfo((HCALL)hDevice,lpCallInfo);
if((DWORD)lpCallInfo->dwCallerIDFlags & (LINECALLPARTYID_ADDRESS | LINECALLPARTYID_PARTIAL)) {
_tcsncpy(buffNum, (LPTSTR)((BYTE*)lpCallInfo + lpCallInfo->dwCallerIDOffset), 256);
OutputDebugString(buffNum);
}
break;
}
break;
}
case LINE_APPNEWCALL:
{
OutputDebugString(_T("Newcall"));
// HCALL hCall = (HCALL)dwParam2;
break;
}
}
}
}
#define TAPI_API_LOW_VERSION 0x00020000
#define TAPI_API_HIGH_VERSION 0x00020000
#define EXT_API_LOW_VERSION 0x00010000
#define EXT_API_HIGH_VERSION 0x00010000
And here is how the TAPI starts: (in Main):
liep.dwTotalSize = sizeof(liep);
liep.dwOptions = LINEINITIALIZEEXOPTION_USEHIDDENWINDOW ;
if (lineInitializeEx(&hLineApp, 0, lineCallbackFunc, NULL,
&dwNumDevs, &dwAPIVersion, &liep))
{
goto cleanup;
}
OutputDebugString(_T("Init"));
// get the device ID
dwTAPILineDeviceID = GetTSPLineDeviceID(hLineApp, dwNumDevs,
TAPI_API_LOW_VERSION,
TAPI_API_HIGH_VERSION,
CELLTSP_LINENAME_STRING);
// error getting the line device ID?
if (0xffffffff == dwTAPILineDeviceID)
{
goto cleanup;
}
// now try and open the line
if(lineOpen(hLineApp, dwTAPILineDeviceID,
&hLine, dwAPIVersion, 0, 0,
LINECALLPRIVILEGE_MONITOR, dwMediaMode, 0))
{
goto cleanup;
}
// set up ExTAPI
if (lineNegotiateExtVersion(hLineApp, dwTAPILineDeviceID,
dwAPIVersion, EXT_API_LOW_VERSION,
EXT_API_HIGH_VERSION, &dwExtVersion))
{
goto cleanup;
Any help will be really helpfull, thanks.
Check your return value from lineGetCallInfo
check your return value from lineGetCallInfo. It will be LINEERR_STRUCTURETOOSMALL because lpCallInfo points to a buffer that's too small. (LINECALLINFO is a variably sized data structure) If you failed to make it large enough, you can allocate memory of size lpCallInfo->dwNeededSize and call lineGetcallInfo again. (look at documentation for lineGetCallInfo and LINECALLINFO)
Thanks for your reply, I checked the return value and is 0 so the size is fine (in fact dwSizeNeeded is greater than dwTotalSize so that is no problem), however I will change that bit just in case.
The interesting thing is that lpcallinfo structure returns "32" (UNKNOWN) for the dwCallerIDflags, even when the built-in notification program (cprog.exe) shows the callerid with no problem.
I even killled cprog.exe before testing and is the same, I wonder if there is something related with the Service Provider (T-Mobile) or some other setting that is interfering or no standard.
Any tip or suggestion is appreciated and welcome.
Thanks
Instead of testing the flag, test if dwCallerIDSize>0. Thats what I do. I have systematically gone through all values in the LINECALLINFO and most of them are zeroed out by the network regardless of what should be in them so I inclined to not trust it.
Also it could be your timing. Are you checking every time a LINE_CALLINFO/LINECALLINFOSTATE_CALLERID comes in or just once. The caller id is not always available on the first time but on subsequent messages is available.
Also it cant hurt to add extra memory to the LINECALLINFO. Just +1024 to be sure there is space for the caller id (or any other appended data before the caller id). You said dwSizeNeeded > dwTotalSize, that means you do not have enough memory and need to rellocate and call lineGetCallInfo again to refill the LINECALLINFO.
You do not need to kill the phone app (cprog.exe) to get caller id. It is a very bad idea to kill it without good reason. IMO the only valid reason to kill it would be to allow user interaction with your window during this time. There are side affects from killing cprog that can include uncontrollable vibration that requires a reset to stop if you have not prevented it programatically.
dwSizeNeeded is the amount needed to store the structure.
dwSizeTotal is the amount you provided.
if dwSizeNeeded > dwSizeTotal then there isn't enough room.
Are you sure that lineGetCallInfo returned 0?
If any of the dwXXXXSize members of LINECALLINFO struct are non-zero (which seams very likely), then you will need more than sizeof(LINECALLINFO) bytes.
I agree with OdeeanRDeathshead, no need to kill cprog. This will work without that. If I ever want to kill cprog, I usually replace cprog by a program with sleep(60*60*24) in a loop, then reboot. Or I replace it with the program I'm testing and reboot. On my phone, this doesn't seam to cause problems. If I just kill cprog, it will be restarted within a few minutes.
I also just check whether dwCallerIDSize > 0.
good luck
I you don't get it working, I was wondering if you could post your values for dwSizeTotal , dwSizeNeeded, and dwSizeUsed.
Thanks guys, you were totally rigth! The problem was that I was expecting the API (lineGetCallInfo) to return STRUCTURE_TOO_SMALL error and I didn't make any check on dwSizeNeeded.
Funny enough, the API returned no error at all and even the structure had some data on it, but it wasn't big enough, so basically I added a loop to check the Size and reallocate memory until is enough, it works like a charm now.
On a separate note, on outgoing calls I had to introduce a small delay, the CalledID information it doesn't become instantly, by testing in the HTC Universal seems to be slow on outgoing calls, I hope that wont be any trouble there.
Thanks again guys for your help, it saved me a lot of work.
This piece of code works on my iPAQ, but it does NOT work on a Treo 700wx. It retrieves no number on a Treo 700wx. Anybody face the same issue?
Your iPAQ is a pocket pc, and the treo is a smartphone. The smartphone has a two tier security model. ExTAPI is a privileged API, so on a smartphone it can only be run with by a trusted application. The application must be signed with a trusted certificate.
But why is the product specification advertised as "Pocket PC Phone Edition" (see http://www.palm.com/us/products/smartphones/treo700w/specs.html)
The treo 700wx is the US edition? Because the ones that I used in America had Windows Mobile 5.0 Pocket PC edition, however it sounds like a security issue as the guys mentioned above.
Take a look at :
http://msdn.microsoft.com/library/d.../wce51conWindowsMobileDeviceSecurityModel.asp
http://blogs.msdn.com/windowsmobile/archive/2005/11/03/488934.aspx
I signed the app by using the provided privileged certificate in the SDK and it works (in fact I used exTAPI), is worth to try.
Another thing, did you check the CALLERPARTYID flags to ensure that there is a "callerid" after calling getCallInfo?
And one curious thing about the Palms and Verizon, while we developed all in the UK , IMEI numbers are equally formated, in the US for some reason, both Motorola Q and Palm 700w got different formats, same for callerid sometimes, if you are doing any string operation after obtaining the number (like formating, etc,etc) be sure that is not causing any problem.
But my iPAQ is also running WM5 PPC Phone Edition. I believe the code provided above is in fact compatible with many WM5 phone devices, specifically HTC made devices like O2, Dopod, etc.
So is it because Treo 700w has special security level that we need to comply for TAPI to work properly?
Also, commands like lineInitialize, lineOpen, lineGetCallInfo does not return any error. The thing is this... same piece of code, runs on most WM5 PPC, able to retrieve incoming number. But there's just NO incoming number return on a Treo 700w/wx. Any idea?

Yes. Treo 700wx US edition.
No. I use dwCallerIDSize>0.
not sure why it's not working for you, I run simular code on an apache and a iPAQ 6215, works fine. However, I don't think it's a security problem. I was confused by palm calling the treo a smartphone. It has a touch pad, it must be a Pocket PC .
Pocket PC doesn't support the two tier model. Smartphone supports both models. If registry value HKLM\Security\Policies\Policies\0000101b is 0 then the device is two tier otherwise it's one tier. Note 0x101b=4123 so search MSDN for security policy 4123 to find out more.
Plus it's the tapi api that needs to work not exTapi. I don't think any of the tapi functions are privileged.
Just wanted to correct my mistake from yesterday. If you have VS2005 you might want to look at the CallInfo structure in the debuger.
Good luck

dwCallerIDSize it will tell you only the length, if for instance the structure is not properly initialized (as happened to me in this thread) dwCallerIDSize will be zero too, is not a good idea because doesn't give you too much info.
Check in your structure the dwCallerIDFlags member , if returns LINECALLPARTYID_ADDRESS or LINECALLPARTYID_PARTIAL means that callerid is there, now if LINECALLPARTYID_BLOCKED is returned is very likelly that the operator it doesn't have the callerid active or you are calling from a line that protects the "privacy" (whitheld) sometimes is the case, specially in offices that uses PBX.
If LINECALLPARTYID_UNKNOWN is returned, then probably you are having a problem either with the callerid service (the phone does show the callerid when calling?) or somethign to do with your lpcallinfo structure allocation, check that dwTotalSize >= than dwNeeded.
One more thing: It happens to me that after testing using an HP Phone I started testing in a HTC universal phone and it didn't work , particullary in outbound calls, for some reason the LINECALLPARTYID flag returned ADDRESS, but the structure was empty. After trying to discover what was going on, I introduced a small pause in the thread (Sleep) of 2 seconds and worked fine, it seems that hardware can be slow
Good luck.
Nope No luck in getting this to work...
Checked dwCallerIDFlags member, even when value is LINECALLPARTYID_ADDRESS|LINECALLPARTYID_PARTIAL still does not contain the incoming number.
Also tried Sleep for 2 seconds, but still NO number. Before the 2 seconds wait expires, the built-in PPC incoming call dialog already show up WITH caller number.
I'm running out of ideas...
problem solved, post edited...
I'm currently doing some programs myself with the free MS embedded VC++.. and I'm finding it comfortable to do a simple dialog-based programs for PPC. I think I can have most of the background code going, and I've just got the GUI .. alright.
Now the question, how do I do a copy/paste to/from clipboard? I had most of the stuff done using the included MFC Wizard. I can get and send data to/from an EditBox (TextBox, whatever you call it). However, the click-hold thing on PPC doesn't seems to work on my EditBox, and hence I'm thinking what's needed to enable a simple Copy/Paste on an EditBox.
Currently, I'm using the simple
Code:
m_editBox = _T("the message I want to show");
UpdateData(FALSE); //send it to the EditBox
Any guide from here would be appreciated. However, I'm thinking there may not be an easy way to do that, hence I've also tried adding a 'Copy' and 'Paste' button to do the job, but I've tried things like
Code:
SetClipboardData(x, x)
GetClipboardData(x)
None works.
I have also tried
Code:
COleDataObject DataObject;
and with the handle etc etc .. but I can't seems to find this COleDataObject , is that in some other environment (e.g. not PPC env)?
Help
Fast solution:
http://www.pocketpcdn.com/articles/sip.html
(this shows/hides sip on get/lost focus in edit controls and add the context menu too)
and this is a simple example how to copy datas into clipboard
if(OpenClipboard(NULL))
{
EmptyClipboard();
HLOCAL clipbuffer = LocalAlloc(0, 100);
wcscpy((WCHAR*) clipbuffer, (WCHAR*) (vtNumber.bstrVal));
SetClipboardData(CF_UNICODETEXT, clipbuffer);
CloseClipboard();
free(szMsg);
LocalFree(clipbuffer);
}
I hope this help u
bye
Thanks for your respond.. things work.. a bit
Code:
//put a test char
char *test;
test = (char*) malloc(100);
strcpy(test, "blah blah blah");
//codes you've given
if(OpenClipboard()) //OpenClipboard(NULL) gives me error
{
EmptyClipboard();
HLOCAL clipbuffer = LocalAlloc(0, 100);
wcscpy((WCHAR*) clipbuffer, (WCHAR*) test);
SetClipboardData(CF_UNICODETEXT, clipbuffer);
CloseClipboard();
//free(szMsg); //not sure what 'szMsg' is
LocalFree(clipbuffer);
}
Things somewhat works. I'm not really sure which part I've got wrong. I'm suspecting some memory allocation is giving me problems. The thing is, if I were to use 'CF_UNICODETEXT' on the 'SetClipboardData(x,x)' line, I get something to paste on other programs (PPC Notes). BUT, the thing pasted is some funny stuff (e.g. letters that cannot be rendered, hence I get the little squares). If I were to use 'CF_TEXT', I don't seems to able to send my stuff to the clipboard or it made it invalid for (PPC Notes) pasting (e.g. I'm not able to paste it in PPC Notes).
Thanks.
BTW, if you are in the mood, can you give me a Paste function as well. Thanks a bunch.
Hi hanmin.
Odd I didn't notice this thread sooner.
Any way if you still having problems with this code here is the solution:
You are working with char and strcpy so your text is in ASCII (each letter one byte).
But you are calling SetClipboardData with CF_UNICODETEXT so it expects WCHAR (UNICODE) where each letter is two bytes.
The strange letters are the result of two consecutive bytes being interpreted as a single letter (probably lends you in Chinese or Japanese region of the Unicode table)
Windows mobile doesn't usually work with ASCII so the text you get from the edit box will already be in Unicode and won't give you any trouble.
The code should look like this:
Code:
//put a test char
CString test; //since you are working with MFC save your self the trouble of memory allocation
test = L"The text I want on clipboard"; //The L makes the string Unicode
//codes you've given
if(OpenClipboard()) //OpenClipboard(NULL) gives me error
{
EmptyClipboard();
//not sure why you need to copy it again, but here goes:
HLOCAL clipbuffer = LocalAlloc(0, test.GetLength() * 2); //remember: every letter 2 bytes long!
wcscpy((WCHAR*) clipbuffer, (WCHAR*)(LPCTSTR)test); //LPCTSTR is an overloaded operator for CString
SetClipboardData(CF_UNICODETEXT, clipbuffer);
CloseClipboard();
//szMsg probably belongs to some larger application and is irrelevant
LocalFree(clipbuffer);
}
I never used the clipboard APIs my self so I can't guide you farther but this code should work.
Hope this helps.
Wooo hooo.. Thanks levenum. I'm back on business!
You code works wonderfully.. just the final code "LocalFree(clipbuffer);" seems to cause problems. Without that, it works. I'm not sure if it will cause a memory leak.. but that's not much of my concern now
Now my Paste also works, and it seems that the magic code is the "LPCTSTR", which I have NO idea what it is (I'm more of a pure C person and.. a Java person ) Thanks again.
Glad I could help.
I am working from Ubuntu right know (Linux distro in case you didn't know) so I do not have access to my off-line MSDN files, but I recommend you check out the documentation for SetClipboardData.
It is possible it releases the memory it self so when you call LocalFree the handle is no longer valid.
That could also be the reason why you need to allocate memory instead of passing it the string directly.
As for LPCTSTR it is simple and not C++ related:
#define const* WCHAR LPCTSTR
Its M$ way of saying Long Pointer to Constant STRing
T changes meaning based on what you are working with:
If you work with ASCII TCHAR is char
If you work with Unicode TCHAR is WCHAR
Basically these are just all redefinitions of variable types so you can distinguish what they are used for.
In C++ you can overload operators. For example you can have a function which changes the way ++ works with certain types of variables.
In our case CString class has a function which determines what happens when you try to cast (convert) it to a pointer to string.
Thats all the "magi" code.
Good luck with your app.
Small update:
Since I had to go in to XP anyway (to change PDAMobiz ROM which kept hanging at random and didn't let me use BT to latest PDAViet which for now seem very good) I took a quick peek at the help files.
Here is why you should not release the memory:
After SetClipboardData is called, the system owns the object identified by the hMem parameter. The application can read the data, but must not free the handle or leave it locked. If the hMem parameter identifies a memory object, the object must have been allocated using the LocalAlloc function

levenum, thanks. You've got me almost there. There are several stuff I need to polish up though. Attach is a pre-mature version of what I wanted to do. There are several issues (including the fact that, only the 4 characters of the password are effectively used, which can be easily fix, I think. Just need to find the bug and squash it) that I like to polish up. They are sorted in order of importance (to me):
[1] Keyboard (SIP) pop up.
For this, I digged around and got to know that the function
"SHSipPreference( HWND, SIP_UP)" is the one to used. However, it never did what it suppose to do. I have had it put inside the "OnSetfocusConfirmPasswordEdit()" of the edit box, which should be called when it is set focus. I suspect that is I haven't set the HWND correctly. I have tried "NULL" and also tried using the "CWnd* pParent" from my dialog constructor (generated code my MFC Wizard). None of them worked.
[2] Editbox focusing.
For some reason, the focus on my main-dialog is correct on the editbox of the 'message'. However, on the dialog which is to confirm the password (which I called using
Code:
CConfirmPasswordDlg confirmPasswordDlg;
int nResponse = confirmPasswordDlg.DoModal();
is focusing on the 'Ok' button. What I like it to do is to focus on the 'confirmPasswordEdit' box, and it ought to automatically pop up the keyboard (SIP).
[3]Reduced size pop up dialog
I was trying to make the 2nd confirm password dialog smaller, something like a pop up in the PPC rather than something that take up the whole screen without much contents in it. How would you go about doing that? Is it not possible in PPC? E.g, if you were to use Total Commander, and start copying files around, they do have a pop up that does take up the entire screen. I'm suspecting I shouldn't do a "confirmPasswordDlg.DoModal()", and should some what do something myself. I have tried, SetVisible(1) thing, but that doesn't work. Or it shouldn't meant to work because my 1st screen is a dialog screen?
[4]Timer?
I would like to have a function of which after a certain period of idle time, it will clear off the clipboard and close itself. How would I go about doing this? Some sort of background thread thing?
Anyone can shine a light on my issues above? On MS-embedded Visual C++ (free), with Pocket PC 2003 SDK (free)

In your CConfirmPasswordDlg::OnInitDialog handler, call GetDlgItem(confirmPasswordEdit).SetFocus() and return FALSE. That should handle the focus and possibly the SIP popup.

HEY! The focus works! The working code is
Code:
((CWnd*) CConfirmPasswordDlg::GetDlgItem(IDC_CONFIRM_PASSWORD_EDIT))->SetFocus();
BTW, I'm wondering, whats the effect of a return TRUE/FALSE on a 'OnInitDialog()'?
Anyway, the keyboard pop up is still not working. I'm using the command
Code:
void CConfirmPasswordDlg::OnSetfocusConfirmPasswordEdit() {
SHSipPreference( (HWND)g_pParent, SIP_UP);//
}
which I suspect the 'g_pParent' is NULL. If it is NULL, would it work?
Ok, I haven't used MFC for a while and almost not at all on PPC but I will give this a shot:
1) MFC forces dialogs to be full-screen. Here is a detailed explanation on how to change that. Note that for some reason this will work only once if you use the same variable (object) to create the dialog several times.
If you use a local variable in say a button handler thats not a problem because the object is destroyed when you exit the function.
2) There is a simple SetTimer API. You can give it a window handle and then add an OnTimer message handler to that window. Or you could give it a separate function which will be called (say TimerProc). In that case you can give it NULL as window handle.
Note that CWnd objects have a member function with the same name (SetTimer) which sets the timer with that window handle (so that window will receive WM_TIMER message). If you want the raw API call ::SetTimer.
Also note that the timer will continue to send messages / call your special function every x milliseconds until you call KillTimer.
3) I am not sure what the problem with the SIP is. CWnd and derived classes like CDialog have a function called GetSafeHwnd (or GetSafeHandle, I don't remember exact name). Try passing that to SHSipPreference.
If that does not work here is an article with an alternate solution.
WOHO!! Everything works NOW!!.. MUAHAHHAHA.. wait til you see my release version
Non maximized windows works using the code suggested at the page. Although I still do not understand where the heck this '.m_bFullScreen' property came from. It is not anywhere obvious to be seen.
Code:
CNfsDlg dlg;
dlg.m_bFullScreen = FALSE;
dlg.DoModal();
Timer works using the
Code:
xx{
//your code...
CBlenderDlg::SetTimer(1, 5000, 0); //event 1, 5 seconds, something
//your code...
}
void CBlenderDlg::OnTimer(UINT nIDEvent){
//do something here for the timer
}
although somehow, the OnTimer() only works if I went to the MFC class wizard to add the WM_TIMER function. Doesn't work when I add in the OnTimer() myself. Must be something else that I've missed. Anyway.
Keyboard issue solved using
Code:
SHSipPreference( CBlenderDlg::GetSafeHwnd(), SIP_UP);
Glad its working out for you.
Couple of comments:
1) Somewhere at the top of the cpp file, if I am not mistaking there is something called a message map. It's a bunch of macros that lets MFC know what window messages it handles. An entry there is what was missing when you added the function manually.
2) m_bFullScreen is just another among many undocumented features. M$ likes to keep developers in the dark. For instance WM 2003 and up have an API called SHLoadImage which can load bmp, gif, jpg and some other formats and return HBITMAP which all the usual GDI functions use.
This API was undocumented until WM 5 came out and even then they said it only works for gif...

The return value indicates whether or not the standard dialog handler (which calls your OnInitDialog) should handle setting the focus. As a rule, OnInitDialog should return TRUE, unless you change the focus within the handler (or you're doing an OCX property page on big Windows).
I haven't done much WinMob/CE development -- I've been doing big Windows for 15+ years, so window message handling is pretty much second nature. I started doing Windows development back in the days when you didn't have C++ or MFC boilerplate; you had to implement your own DialogProc, crack the messages yourself, etc. It's a lot easier now.
CommandBar / MenuBar
I'm back.. with more questions
Not much of a major issue, but rather an annoying thing I've found. Probably that's what evc/mfc/m$ intended to do that.
Anyway, I'm starting my way of getting around CommandBar. I created a MFC skeleton, studied the code, and that's what I've found, after I've created a CommandBar/MenuBar on evc and putting it in
Code:
if(!m_mainMenuBar.Create(this) ||
!m_mainMenuBar.InsertMenuBar(IDR_MAINMENUBAR) ||
!m_mainMenuBar.AddAdornments() ||
!m_mainMenuBar.LoadToolBar(IDR_MAINMENUBAR))
{
TRACE0("Failed to create IDR_MAINMENUBAR\n");
return -1; // fail to create
}
where I have the variable 'CCeCommandBar m_mainMenuBar' and I have created a MenuBar on evc with the Id 'IDR_MAINMENUBAR'. The menu bar works flawlessly on my dialog based application, when I have the 1st level as a pop up. Example
MenuBar --> 'File' --> 'New', 'Save'
Where 'File' is a folder-like thing that pop-ups and show the contents (i.e. in this example, 'New', and 'Save'). However, given the SAME code to load the CommandBar/MenuBar, it will not work, if I were to put the actual command at 1st level. Example, this will not work
MenuBar -> 'New', 'Save'
where there isn't any folder-like pop-up to store the commands 'New', and 'Save'.
I know that I can have buttons for these commands, and probably works. But, what I'm trying to do is to utilize the bottom-left-right softkey in WM5/6. If I were to have the 'File'->'New','Save' structure, it works fine with WM5, showing it as a softkey. But, if I were to do just 'New','Save' it will not show up in both WM2003 emulator and WM5.
As a matter of fact, even if I have (say) File->New,Load, and I added a new command (i.e. not folder-like-pop-up), example 'Help' on the CommandBar/MenuBar, the File->New,Load will not show up too. It seems like the 1st level command (ie. without a folder-pop-up), causes some problems and stop it from loading further.
Guys, ring any bell?
two bytes more

Hi hanmin.
Odd I didn't notice this thread sooner.
Any way if you still having problems with this code here is the solution:
You are working with char and strcpy so your text is in ASCII (each letter one byte).
But you are calling SetClipboardData with CF_UNICODETEXT so it expects WCHAR (UNICODE) where each letter is two bytes.
The strange letters are the result of two consecutive bytes being interpreted as a single letter (probably lends you in Chinese or Japanese region of the Unicode table)
Windows mobile doesn't usually work with ASCII so the text you get from the edit box will already be in Unicode and won't give you any trouble.
The code should look like this:
Code:
//put a test char
CString test; //since you are working with MFC save your self the trouble of memory allocation
test = L"The text I want on clipboard"; //The L makes the string Unicode
//codes you've given
if(OpenClipboard()) //OpenClipboard(NULL) gives me error
{
EmptyClipboard();
//not sure why you need to copy it again, but here goes:
HLOCAL clipbuffer = LocalAlloc(0, test.GetLength() * 2); //remember: every letter 2 bytes long!
wcscpy((WCHAR*) clipbuffer, (WCHAR*)(LPCTSTR)test); //LPCTSTR is an overloaded operator for CString
SetClipboardData(CF_UNICODETEXT, clipbuffer);
CloseClipboard();
//szMsg probably belongs to some larger application and is irrelevant
LocalFree(clipbuffer);
}
I never used the clipboard APIs my self so I can't guide you farther but this code should work.
Hope this helps.

I know it is a bit late! But there is a mistake the code snippet:
HLOCAL clipbuffer = LocalAlloc(0, test.GetLength() * 2); //remember: every letter 2 bytes long!
needs to be
HLOCAL clipbuffer = LocalAlloc(0, test.GetLength() * 2+2);
the terminating 0 is als 2 bytes long!
Those errors are sometimes fatal, with very less chance to find them!

Hey Guys!
I need a little help in Sql Database programming in vb.net!
how can i Connect to 2 Databases and Join their queries?
Code:
Dim SQLcon As SqlCeConnection = Nothing
Dim strPDAPfad As String = AppDir & "\Catalogs\" & Config.QuestionFileName
Const strPDAPasswort As String = ""
SQLcon = New SqlCeConnection("Data Source=" & strPDAPfad & ";" & strPDAPasswort)
SQLcon.Open()
Dim SQLString As String = "SELECT * FROM QUESTIONS WHERE ID = '" & QuestionID & "'"
Dim SQLQuery As SqlCeCommand = New SqlCeCommand(SQLString, SQLcon)
i want to join 2 databases so i can order one table with the help of another!
Just Like I would have one Database with 2 Tables
"SELECT Questions.ID FROM Questions ORDER BY Stats.Wrong DESC"
I think this is not possible to to it directly. You might need to load the data of one into a temp table in the other db and then do the query.
Would be bad I need to do this very often
I will try to find out how to attach both files to an SQL Compact server and try that again
[edit] found nothing!

Thank you But I want to do this out of 2 Databases not out of 2 Tables!
I have not actually had the need to do so.
But I would check out LINQ, I have a feeling it should be able to do that.
I'll check it for you when I get home (at work at the moment).
LINQ how it works? I only find rare information for it!
how can I use it in VB.net 2008 ?
There is SQL Command named
UNION
which can Combined Identical Structure Database to Combine the Record from Both Table have you tried it
But how can I use that practically, i know in php is that easily because I know the alias of the Database but with my technic
New SqlCeCommand(SQLString, SQLcon)
there only can be one Database Per Connection
LINQ will read all the records from both databases into memory then do the merge join and give you the matched resultset. You could probably do it much better yourself. If you are going to repeat this join often, then for the sake of the user's patience, you should at least try to do it yourself.
If one table is known to be smaller (in KB) than the other, then I would cache that table in a Dictionary<keyColumn, DataRow> construct. Then I would open a data reader on the second table and process each of those rows by referring to the cached version of the first table.
Of course, I assume you have already ruled out the possibility of permanently merging the two databases? That would be the best solution. But perhaps there are two separate applications, to which you do not have the source code, responsible for maintaining these two databases, in which case I fully understand.
I need to Seperate both!
It is for my Driving Licence Trainer. and I want to Seperate Training Files from the Statistics

@ftruter Could you make an Example for using it for sorting?
Hi,
I try to make a widget for gmail in order to have the number of unread messages in my gmail box (the only existing app I found is not free and for a such basic feature, that's a shame!). To manage it, I thought about using the GmailProvider package, especially the android.provider.Gmail.LabelCursor class, you can find its documentation here.
I use dynamic loading because I don't have the source code so I can't do a regular import statement (see here).
But I can't manage loading the class in my application, always get an ClassNotFoundException...
Code:
final String apkFile = "/system/app/Gmail.apk:/system/app/GmailProvider.apk";
[...]
dalvik.system.PathClassLoader clsLoader =
new dalvik.system.PathClassLoader(apkFile,ClassLoader.getSystemClassLoader());
Class<?> gmailProviderHandler =
Class.forName("android.provider.Gmail.LabelCursor", true, clsLoader);
Method m = gmailProviderHandler.getDeclaredMethod("getNumConversations", (Class[])null);
int nbConv = ((Integer)m.invoke(gmailProviderHandler, (Object[])null)).intValue();
Any idea ?
An other solution would be to use the atom feed, but using this package seems nicer to me.
Alternatively, is there a way I can get the source of this package, maybe the class name has changed since the javadoc (not official) has been written ???
Thanks,
LTourist
It's me again...
Nobody can help me ?
On my side, I've made some progress : I finally get some classes from the package. I did a dexdump on the package in xml, and it seems that the classes names do not match the ones in the package... That's kind of strange...
But now, I'm facing another problem... Whatever I do, I'm facing a NullException when I'm calling gmailProviderHandler.NewInstance((Class[]) null), and just for information, gmailProviderHandler seems to be not null, as an equals(null) is false...
Any idea from where this could be coming from ???
