Hello,
I try to retrieve (then set) the volume, ring type ... of my XDA using TAPI
I call phoneInitializeEx, phoneOpen, phoneGetVolume but I always get the same value for the volume (even if I chnage it of course)
Does anybody knows why ?
Does anybody have and can post a sample code source showing how to unse these functiuns (phoneInitializeEx, phoneOpen, phoneGetVolume, phoneGetStatus ...)
Regards.
To set the phone volume (in mono) try:
Code:
set(DWORD dwVolume)
{
if (dwVolume > 0xFFFF) dwVolume = 0xFFFF;
dwVolume += dwVolume * 0x10000;
DWORD ret;
switch ((ret = waveOutSetVolume(0, dwVolume))) {
case MMSYSERR_NOERROR:
break;
case MMSYSERR_ERROR:
break;
case (etc....)
}
To get the volume, try:
Code:
DWORD get()
{
DWORD dwVolume;
DWORD ret;
switch ((ret = waveOutGetVolume(0, &dwVolume))) {
case MMSYSERR_NOERROR:
break;
case MMSYSERR_ERROR:
break;
case (etc...)
}
// Return average of left and right:
if (dwVolume > 0xFFFF) {
dwVolume = ((dwVolume & 0xFFFF) + (dwVolume / 0xFFFF)) / 2;
}
return dwVolume;
}
This is code for XDA I. I have not tried this on XDA II which as we know, has two volume channels.....
Ben.
I upgraded my XDA1 with WM2003 and I have 2 channels for the volume too.
I will try your code but I think this will change only the system volume (I will need to do that too so thanks) but not the phone volume.
First I want to pilot the phone settings (ring, volume...) from an application.
And it seems that only TAPI can do it... but it is not working for the moment
Glad the code will be useful.
If you find the correct method for XDA II, please let me know, I'll need it my self soon.
Ben
Your code works well to set/get the sytem volume
I just modifed it a little as the output is mono
Code:
//**********************************************************************
//Set The System Volume
//Steps (0,13107,26214,39321,52428,65535)
DWORD setVolume(DWORD dwVolume)
{
if (dwVolume > 0xFFFF)
dwVolume = 0xFFFF;
if (dwVolume < 0x0000)
dwVolume = 0x0000;
DWORD ret;
switch ((ret = waveOutSetVolume(0, dwVolume)))
{
case MMSYSERR_NOERROR:
break;
case MMSYSERR_ERROR:
break;
default :
break;
}
return 0;
}
//**********************************************************************
//Get The System Volume
DWORD getVolume()
{
DWORD dwVolume;
DWORD ret;
switch ((ret = waveOutGetVolume(0, &dwVolume)))
{
case MMSYSERR_NOERROR:
break;
case MMSYSERR_ERROR:
break;
default :
break;
}
dwVolume = (dwVolume & 0xFFFF);
return dwVolume;
}
But the phoneGetVolume still gives incoherent results
Someone see something wrong in the code below ?
I set the phone volume to 0 on the device but PhoneGetvolume send me 40092 ???
Code:
LONG result;
HPHONE hPhone;
DWORD dwVolume;
DWORD dwRingMode;
DWORD dwNumDevs= 01;
DWORD dwAPIVersion=0x00020002;
PHONESTATUS PhoneStatus;
HPHONEAPP hPhoneApp = 0;
PHONEINITIALIZEEXPARAMS PhoneInitializeExParams;
PhoneInitializeExParams.dwTotalSize = 2 * sizeof(PHONEINITIALIZEEXPARAMS);
PhoneInitializeExParams.dwOptions = PHONEINITIALIZEEXOPTION_USEEVENT;
// PhoneInitializeExParams.dwOptions = PHONEINITIALIZEEXOPTION_USEHIDDENWINDOW;
result = phoneInitializeEx(&hPhoneApp,NULL,NULL,NULL,&dwNumDevs,&dwAPIVersion,&PhoneInitializeExParams);
result = phoneOpen(hPhoneApp, 0, &hPhone, dwAPIVersion, 0, 0,PHONEPRIVILEGE_OWNER);
result = phoneGetVolume(hPhone,PHONEHOOKSWITCHDEV_SPEAKER,&dwVolume); //range 0x00000000 to 0x0000FFFF (65535)
In fact when I set the phone volume using
PocketSetVolume the vlaue is well saved because I get it when I use after PocketGetVolume.
But the phone volume is not really changed ?
Nobody has a sample that uses these functions ?
Or not obligatory these functions but others functions that change the phone volume ?

I have found that by changing the following registry keys, I can change the volume of the Phone
[HKEY_CURRENT_USER\ControlPanel\Volume]
"Ringer"=dword:00000000
Use hex 00000000, 33333333, 66666666, 99999999, cccccccc, ffffffff
[HKEY_CURRENT_USER\ControlPanel\SoundCategories\Ring]
"InitVol"=dword:00000000
Use hex 0, 1, 2, 3, 4, 5
This work beautifully for my Qtek running WM2003, but I have tried the same approach for the system-volume by changing
[HKEY_CURRENT_USER\ControlPanel\Volume]
"Volume"=dword:00000000
Use hex 00000000, 33333333, 66666666, 99999999, cccccccc, ffffffff
But this does not work! I have checked the registry and the value goes in correctely (The in-system volum control stores the same values in the same key).
How can I use the above code-snippets from the .Net Compact Framework? (I'm guessing a P/Invoke but what DLL is the call hidden in)
Cato
I am trying to make it works, but fail...please let me know if you know how to use the registry to update it...my email is
[email protected]
Thanks
I used the P/Invoke sample from Microsoft to get a working sample that read and updated the registry, and simply tried all possible combo's of a 4byte-array to see what would produce the correct result
Cato
I found a article mention it !!!
http://www.cegadgets.com/winceregfaq.htm#2.8 Where are volume and sound settings stored?
Not sure it works or not !!!
Please let me know if you know how to use the AudioUpdateFromRegistry, defined in coredll
Thanks :wink:
One more acticle !!!
http://www.pocketpcdn.com/forum/viewtopic.php?t=111
But I dunno how to make it works.
Any runnable example?
Hello,
after many tries I didn't find how to use TAPI functions ... this seems not towork ..
But you can change all the phone settings (volume, ring mode, ring tone, notifications ...) in the registry ... as I did for PocketZenPhone
See under that key HKEY_CURRENT_USER\ControlPanel
For the system volume I use the functions I posted upper
Hey, any example to do it?
Thanks zendrui
If you use EVC
Simply open the registry key
HKEY Key;
RegOpenKeyEx(HKEY_CURRENT_USER,_T("\\ControlPanel\\Volume"),0,0,&Key);
Then use RegQueryValueEx to retrieve the value/setting you want
Hi zendrui,
I am able to update the registry, but I am not able to call AudioUpdateFromRegistry to notify the system to update the status from registry.
Could you able to exeute this API?
Thanks,
Paul
Sorry for the last post didn't have the keys in my mind
So to change the phone volume here are the keys needed
Code:
//dwPhoneVolumeLevel between 0 and 0xFFFFFFFF
res = RegOpenKeyEx(HKEY_CURRENT_USER,_T("\\ControlPanel\\Volume"),0,0,&Key);
if (res == ERROR_SUCCESS)
{
res = RegSetValueEx(Key,_T("Ringer"),0,REG_DWORD,(LPBYTE)&dwPhoneVolumeLevel,sizeof(DWORD));
if (res != ERROR_SUCCESS)
{
RegCloseKey(Key);
return -1;
}
}
RegCloseKey(Key);
//dwInitVol between 1 and 5
res = RegOpenKeyEx(HKEY_CURRENT_USER,_T("\\ControlPanel\\SoundCategories\\Ring"),0,0,&Key);
if (res == ERROR_SUCCESS)
{
res = RegSetValueEx(Key,_T("InitVol"),0,REG_DWORD,(LPBYTE)&dwInitVol,sizeof(DWORD));
if (res != ERROR_SUCCESS)
{
RegCloseKey(Key);
return -1;
}
}
RegCloseKey(Key);
It changes the phone volume and the display
PS : I post this code hoping is to help people to develop freewares (or low low cost software :wink
COOL !!! Thanks zendrui !!!!
Now I can set the Ringer volume !!!
How about set the system sound volume?
Fot the system volume see upper of this thread I posted the code I use. It works perfect
O yes...It works under eVC++
Let me try to implement it in VS.NET
Thanks

PS: Sorry that I could not get you a working code before but I was under with the flu last week
1) Hi, we works with Pocket PC 2003 (Embedded Visual C++ 4.0). Our target is perform a data call over integrated cellular line. We read that the right mean is TAPI (XDA-Developers forum) because COM2 seem to be owned by RIL layer. We wrote a test program which handles a data call answer. We get the serial port handle returned by "lineGetID()" function for current data call, but when we try to use it through standard communication APIs ("WriteFile()" and "ReadFile()") it doesn't work (no data is read or write from port handle, but there aren't errors returned by APIs). Same code seems to work fine on a HP IPAQ 2210 with a Compact Flash GSM/GPRS card. How can we transfer data so?
2) We noticed a phone answering process is alive (CPROG.EXE) that takes calls' control. We kill this process when we make our tests, but it backs to life after some minutes. How can we take real calls' control?
3) Is the integrated cellular modem Hayes compatible? Is there a way to directly send AT commands to integrated cellular modem?
4) DCB structure "PortDCB" we pass to "SetCommState()" is the following:
PortDCB.DCBlength = sizeof (DCB);
PortDCB.BaudRate = 9600;
PortDCB.fBinary = TRUE;
PortDCB.fParity = TRUE;
PortDCB.fOutxCtsFlow = FALSE;
PortDCB.fOutxDsrFlow = FALSE;
PortDCB.fDtrControl = DTR_CONTROL_ENABLE;
PortDCB.fDsrSensitivity = FALSE;
PortDCB.fTXContinueOnXoff = TRUE;
PortDCB.fOutX = FALSE;
PortDCB.fInX = FALSE;
PortDCB.fErrorChar = FALSE;
PortDCB.fNull = FALSE;
PortDCB.fRtsControl = RTS_CONTROL_ENABLE;
PortDCB.fAbortOnError = FALSE;
PortDCB.ByteSize = 8;
PortDCB.Parity = NOPARITY;
PortDCB.StopBits = ONESTOPBIT;
Is it correct?
Can anybody help me?
Matthew
This DCB params seem do right job....
Code:
PortDCB.BaudRate = 115200;
PortDCB.fBinary = TRUE;
PortDCB.fParity = FALSE;
//PortDCB.fParity = TRUE;
PortDCB.fOutxCtsFlow = FALSE;
PortDCB.fOutxDsrFlow = FALSE;
PortDCB.fDtrControl = DTR_CONTROL_ENABLE;
PortDCB.fDsrSensitivity = FALSE;
//PortDCB.fDsrSensitivity = TRUE;
PortDCB.fTXContinueOnXoff = TRUE;
//PortDCB.fTXContinueOnXoff = FALSE;
PortDCB.fOutX = FALSE;
PortDCB.fInX = FALSE;
PortDCB.fErrorChar = FALSE;
PortDCB.fNull = FALSE;
PortDCB.fRtsControl = RTS_CONTROL_DISABLE;
PortDCB.fAbortOnError = FALSE;
PortDCB.ByteSize = 8;
PortDCB.Parity = NOPARITY;
PortDCB.StopBits = ONESTOPBIT;
problem one shuold be solved ...Hi
Your DCB parameters worked fine.
Hi Matthew.
Your parameters worked fine with my application, i was teting an IMate and you helped me a lot with my next product version.
Thank you.

Dear Matthew,
Hi,
I created a similar application to make a call from one PPC to another using data link. The problem is my program couldn't detect incoming calls. Would you please help me solve this issue?
Do you have any source code that I can learn from it? Also which method did you use? TAPI? COM port? RIL?
I'm very confused. Please help....
Best regards,
A. Riazi
Why is your baudrate 115200 when a CSD connection through TAPI is only at 9600 ?
cause it's TAPI
you can't select bearer capabilities
if you wana select rate use RIL or direct access to COM-ports
mathews help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
hi,
i am facing a similar problem cant send data through writefile api on cellular line
these r code snippets form my cod e
if(dwReturn =lineOpen (
g_hLineApp, // Usage handle for TAPI
g_dwCurrentLineID, // Cannot use the LINEMAPPER value
&g_CurrentLineInfo.hLine, // Line handle
g_CurrentLineInfo.dwAPIVersion,
// API version number
0, // Must set to zero for Windows CE
0, // No data passed back
LINECALLPRIVILEGE_NONE, // Can only make an outgoing call
0, // Media mode
NULL))
g_MakeCallRequestID = lineMakeCall (g_CurrentLineInfo.hLine,
&g_hCall,
szDialablePhoneNum,
0,
NULL);
dwRet =lineGetID(g_CurrentLineInfo.hLine, 0, 0, LINECALLSELECT_LINE, lpVarString,TEXT("comm/datamodem"));
till this its ok it returns a valid comm handle
after that it sends th data over the connected call but doesnt receive anythinga t the other end ...
the problem might be to give a call handle and LINECALLSELECT_CALL in linegteid func tion i tried it but when i use it fails saying cannot obtain the handle .......now i don understand whether its the problem of not obtaining a handle or whether linehandle will work but problem is in communication ...
plz help and add some code snippets for the communication
firstly have you set up the following...
LPLINECALLPARAMS CallParams;
CallParams=(LPLINECALLPARAMS)malloc(sizeof(LINECALLPARAMS)+1024);
memset(CallParams,0,sizeof(LINECALLPARAMS)+1024);
CallParams->dwTotalSize = sizeof(LINECALLPARAMS)+1024;
// This is where we configure the line for DATAMODEM usage.
//its important to note that if you attempt to make a call
//using LINEMEDIAMODE_DATAMODEM, the line must be opened in
//that way to begin with or nothing will happen. ie open lines
//corresponding to what you plan to makecall with.
CallParams->dwBearerMode = LINEBEARERMODE_VOICE;//over voice call
CallParams->dwMediaMode = LINEMEDIAMODE_DATAMODEM;//data transmition
//LINEMEDIAMODE_INTERACTIVEVOICE;//for voice
//specify that we only want to use a call that is not alreay in use.
//Otherwise it can take over calls that are in progress
CallParams->dwCallParamFlags = LINECALLPARAMFLAGS_IDLE;
//specify to use the first address
CallParams->dwAddressMode = LINEADDRESSMODE_ADDRESSID;
CallParams->dwAddressID = 0;
next check the line you want to use and make sure...
if(lpDevCaps->dwBearerModes & callModeData)//datamode
{
if(lpDevCaps->dwBearerModes & callModeVoice)
{
//then check the media mode
if(lpDevCaps->dwMediaModes & LINEMEDIAMODE_DATAMODEM)
{
if(lpDevCaps->dwMediaModes & LINEMEDIAMODE_INTERACTIVEVOICE)
{
//use it
}
}
}
}
next when you get an incoming call etc get the handle......
HANDLE myTapiManager::getHandle()
{
HANDLE hModem=NULL;
CString name="";
classType="comm/datamodem";
DWORD dwSize = sizeof(VARSTRING) + 2048;
DWORD dwRet = 0;
do
{
LPVARSTRING lpVarString = (LPVARSTRING) new BYTE[dwSize];
lpVarString->dwTotalSize = dwSize;
//the commented out values are what microsoft seem to say
//but cause it to return no handle but only the device class name
dwRet = ::lineGetID(/*hOpenedLine*/NULL, 0,hCall,LINECALLSELECT_CALL /*LINECALLSELECT_LINE*/, lpVarString,
classType);
if ( dwRet == 0 )
{
hModem= * (HANDLE*) ((char*) lpVarString + lpVarString->dwStringOffset);
name= * (LPTSTR) ((char*) lpVarString + lpVarString->dwStringOffset + sizeof(HANDLE));
if(hModem==NULL)
{
MessageBox(NULL,_T("null handle"),_T("handle"),MB_OK|MB_SETFOREGROUND|MB_TOPMOST);
}
else
{
MessageBox(NULL,_T("non null handle, about to call init on port"),_T("handle"),MB_OK|MB_SETFOREGROUND|MB_TOPMOST);
hSerialHandle=hModem;
//you must initialize the port but I do not show it here
initializeIOTimeOuts();
}
break;
}
else if ( dwRet == LINEERR_STRUCTURETOOSMALL )
{
dwSize = lpVarString->dwNeededSize;
delete lpVarString;
lpVarString = NULL;
continue;
}
else
{
// handle errors.........
//
hModem=NULL;
}
}
while (1);
return hModem;
}
this works for me. One problem you may be having is the timing. If you get the handle when the call is offering it will be useless. You must ensure that the call is connected, use the LINECALLSTATE_CONNECTED for this.
cprog dose not effect the opperation of your program, only its ui.
Have you looked at the zip I put in this post ?
http://forum.xda-developers.com/viewtopic.php?t=18978
It may help you with the sending part and getting a handle to Readfile/writefile.
I have never worked on the anwering side so I know nothing on that.
to answer the call that is offering, use LineAnswer. I have tried LinePickup but it has not done what I want. When using lineanswer be aware that the os has already set the number of rings it will ring before the call is actually answered after you answer it. It is normally changed through the phone settings but you can do it programatically if you wish.
Also, you have not mentioned what you are doing with regards to threads. The first time I tried using tapi I spent a lot of time avoiding using multiple threads but it is impracticle. A good number would be 1 for the ui 1 for the line status and 1 for data transfer. Getting your serial handle would the require carefull synchronization.
I have not found benefit in altering any of the port settings. The time-outs for the read/write can make a huge difference though.
Have you checked if there is a class name following the handle in the LPVARSTRING? I have found that if you are doing everything correct except the timing, the name is added but not the handle. This means that the name would be 4 places sooner than it should. In that case the name is in the place where the handle should be and the call still succeeded. Try writing to the port using a string instead of a handle and see how far you get(kidding). To test it just treat the handle you have got as if it where a string and put it in a messagebox. If you can read it then your timing is off.
Lastly your problem could come from how you are setting the api version. Have you been checking the errors generated after all your api calls. There are a lot for tapi that tell you most of what is going on. I have noticed that if you are using the event method for getting line state messages from tapi (ie the correct time to grab the handle) there is something wrong with the way the api version gets negotiated. The event method is part of tapi 2.0 i think so it should be expected that an api version of at least 2.0 is a good version to aim for. For win ce 3.0 docs say that 2.0 is fully supported and parts of 2.1. This is not what actually happens though, I have found that I can't get the event method to work at all (among other things) if I don't pass a min version of 1.1 and a max version of 1.3. This is bizar because by that input tapi should not use any features above 1.3 :?:
guys i ve been trying to set up call params
//Configure line device for a data modem
memset(&LineCallParams, 0, sizeof(LineCallParams));
LineCallParams.dwTotalSize = sizeof(LineCallParams);
LineCallParams.dwBearerMode = LINEBEARERMODE_VOICE;
LineCallParams.dwMediaMode = LINEMEDIAMODE_DATAMODEM;
LineCallParams.dwCallParamFlags = LINECALLPARAMFLAGS_IDLE;
//If multiple addresses on the line, use the first address
LineCallParams.dwAddressMode = LINEADDRESSMODE_ADDRESSID;
LineCallParams.dwAddressID = 0;
the problem is when i pass the lpparam instead of null it reaches to dialing the number and says disconnected: unreachable ..
There is no error while lineopen is passed with LINEMEDIAMODE_DATAMODEM as the 8th parameter i think it shoudl have given an error of media mode not supported at that point only ....but it didnt .....it opened the line fine
when i did not set the datamodem media mode in call params and rest remain as it is ..........the call works fine and is connected ....is it because the datacall facility is not supported and if it is not how can it be activated ....
lReturn = lineOpen(m_hLineApp, m_dwDeviceID, &m_hLine, m_dwAPIVersion, 0 , 0,
LINECALLPRIVILEGE_NONE, LINEMEDIAMODE_DATAMODEM, 0);
g_MakeCallRequestID = lineMakeCall (g_CurrentLineInfo.hLine,
&g_hCall,
szDialablePhoneNum,
0,
NULL); // NULL for default voice call
/**************************/
// lpCallParams);
Firstly, is the phone you are trying to dial a ppc. If yes... the ppc you wish to be the one that answers the call must have opened the line the same way as the dialing one, ie supporting data. If not then it will not even ring when a data call is offering and you will never know if your call was really made.
next look at lineopen.
long opnResult=lineOpen(hLineApp,
deviceID,
&hOpenedLine,
apiNegotiatedForUsedDevice,
0,//not used at all
1,//not used by tapi, but is passed back to this //application to help identify the source of the messages.
//in each line state message. It can be used
//to make sure the message is from a line
//opened by this app.
LINECALLPRIVILEGE_OWNER,// tells it can //accept calls.
LINEMEDIAMODE_DATAMODEM,
NULL);
almost the same but try LINECALLPRIVILEGE_OWNER. This must be set on the receiving end but I also set it on the dialing end.
If the media mode is not supported you will get an error message to tell so. That is the primary way my programs determine the identity of the line to use.
What is the device you are using? I have got bi-directional data transfer to work between ppc 2002 (xda I) and wm2003 se (xda mini). Before 2002 not as many features are supported.
also your call params may be too small
try adding a litle to the end
LPLINECALLPARAMS CallParams;
CallParams=(LPLINECALLPARAMS)malloc(sizeof(LINECALLPARAMS)+1024);
memset(CallParams,0,sizeof(LINECALLPARAMS)+1024);
CallParams->dwTotalSize = sizeof(LINECALLPARAMS)+1024;
.
.
.
.
and what about the number to dial in the call params
// Address to dial
//set its location to be after the normal end of the structure
CallParams->dwDisplayableAddressOffset = sizeof(LINECALLPARAMS);
CallParams->dwDisplayableAddressSize = strlen(szPhNumber);
strcpy((LPSTR)CallParams+sizeof(LINECALLPARAMS), szPhNumber));
then pass the szPhNumber into linemakecall, remember that ppc version
takes unicode.

plz suggest if i need to change anything but as the call is successfully connected when only media mode is not set i guess problem is not with the memory location or anything but lies with the provider not sure ...............
or better maybe if u can suggest how i can do settings on my pocket pc for data calls
If you can't make a Data Modem type call, but you can make a voice call - Then are you sure you have Data Enabled on your Sim.
I'm sure I had that un-reachable error ages ago and it was due to not having Data Enabled. You have to contact your Sim provider to do that.
I have never included the lineTranslateAddress, i just put it in the way the user entered it( with a little error checking). If it works for voice though it must be OK.
With the sim, I have done this using 3 different sims and never had to set anything special on it. I could be lucky I guess and had sims already enabled. I doubt it though because one is 7 years old pre paid and not had any change since purchase. The second in a new pre paid and the 3rd is a full gprs enabled(not that gprs has anything to do with this). There should not be anything in the os to set either as when you do what you have done it is doing the "setup" just programatically.
I remember reading somewhere that the network had to support it but I can't be more specific.
What is your network? What is your device? what is your os?
When you say the voice call is connected what do you mean?..
1)your program at the other end answered.
2)the phone app on the other end answered.
3)your dialing end app received the connected message.
4)the returned value from linmakecall was > (-1).
5)some phone hardware on a real phone answered.
6) (my favourite way) the monitor next to your phone started buzzing, proving something was going on. Thats how I test my gprs connectivity :lol:
Dear all:
I am developping a program to change XDAII's sound.
using waveOutSetVolume() and waveOutGetVolume() can set and get XDAII's volume correctly, when playing multimedia or other applications.
But it does not work for GSM call. I mean in a GSM call, these two functions cannot do anything about gsm's volume.
Who know how to set and get GSM's volume in a call?
using waveOutGetNumDevs() can only return 1, which means only 1 waveform device available. whether it is mean GSM audio device is not a waveform device? then how to control it?
thanks
Do u means ringtone volume?
YES. Do u have any idea?
Not sure if this will work but try looking up phoneSetRing in the help:-
LONG WINAPI phoneSetRing(
HPHONE hPhone,
DWORD dwRingMode,
DWORD dwVolume

hPhone
Handle to the open phone device. The application must be the owner of the phone device.
dwRingMode
Ringing pattern with which to ring the phone. This parameter must be within the range of zero to the value of the dwNumRingModes member in the PHONECAPS structure. If dwNumRingModes is zero, the ring mode of the phone cannot be controlled; if dwNumRingModes is 1, a value of zero for dwRingMode indicates that the phone should not be rung (silence), and other values from 1 to dwNumRingModes are valid ring modes for the phone device.
dwVolume
The volume level with which the phone is ringing. This is a number in the range 0x00000000 (silence) to 0x0000FFFF (maximum volume). The actual granularity and quantization of volume settings in this range are service provider-specific. A value for dwVolume that is out of range is set to the nearest value in the range.

I know how to set ring volume, but how to display it?
Dear all:
Now i can set ring volume according some experts help. they had ever past some guides in this forum. I just re-paste part of my program.
void SetGSMVolume(DWORD *devGSMVolumeLevel)
{
HKEY Key = NULL;
//dwPhoneVolumeLevel between 0 and 0xFFFFFFFF
DWORD res = RegOpenKeyEx(HKEY_CURRENT_USER,_T("\\ControlPanel\\Volume"),0,0,&Key);
if (res == ERROR_SUCCESS)
{
res = RegSetValueEx(Key,_T("Ringer"),0,REG_DWORD,(LPBYTE)devGSMVolumeLevel,sizeof(DWORD));
if (res != ERROR_SUCCESS) {;}
//RegCloseKey(Key);
}
RegCloseKey(Key);
Sleep(500);
}
But I meet another question: I can set any value for the ring, and read it out correctly. But the display on icon is not right. The icon always fixed at some point, I can set it use pen, not program.
Who can help me to synchrize the display and my ring volume?
The value in registry is aligned with what i set, not same with its display.
thanks
I am trying to set the volume to my needs then put it back after. I have use the code from ppc developer network and when that did not set the correct volume I also did the registry as well. Don't worry about "reg", its my registry class and it works fine.
DWORD oldReg=0;
oldReg=reg->readDWORDfromReg(name,path);
reg->saveDWORDtoRegistry(name,path,0xffffffff);
WAVEFORMATEX wf;
wf.wFormatTag = WAVE_FORMAT_PCM;
wf.nChannels = 1;
wf.nSamplesPerSec = 8000 * 1000;
wf.wBitsPerSample = 8;
wf.nBlockAlign = wf.nChannels * wf.wBitsPerSample / 8;
wf.nAvgBytesPerSec = wf.nSamplesPerSec * wf.nBlockAlign;
wf.cbSize = 0;
HWAVEOUT hwo;
DWORD dwVolume=0xffffffff;
DWORD oldVolume=0;
int waveDevice=-1;
UINT numberOfDevices=waveOutGetNumDevs();
for(UINT id=0;id<numberOfDevices;id++)
{
if (waveOutOpen(&hwo,id,&wf,0,0,CALLBACK_NULL)==MMSYSERR_NOERROR)
{
waveDevice=id;
waveOutGetVolume(hwo,&oldVolume);
waveOutSetVolume(hwo,dwVolume);
waveOutClose(hwo);
break;
}
}
.........playing sound here all ok....
//put the volume back
if(waveDevice!=-1)
{
if (waveOutOpen(&hwo, waveDevice, &wf, 0, 0, CALLBACK_NULL) == MMSYSERR_NOERROR)
{
waveOutSetVolume(hwo, oldVolume);
waveOutClose(hwo);
}
}
reg->saveDWORDtoRegistry(name,path,oldReg);
I can set the volume to any value below the origional volume but any attempt to set a volume higher just dose nothing. There are no errors (checking left out here), just the same level. I did not seriously expect the registry part to work as I guess there is some event to trigger that change, but others seem to get results from waveOutSetVolume.
Well, I never tried changing volume by code, but I know TCPMP player does it well and it's open source so might be worth taking a look at.
Thanks levenum, I will give it a look.
Before I got a chance to look at that code I got a result. I have been using PlaySound to play a resource with no volume change working. When I use waveOutWrite to play a buffer containing the same data I can get the volume change I am after. There is still something wrong with my code because the sound gets garbled but I think I will figure that part out. I also want to next test playsound with a file instead of a resource.
<edit>
using playsound with the same file plays clear sound but the volume change is not working. Its a pity because to get the waveoutwrite to work properly i had to fill in the WAVEFORMATEX with the CORRECT values. This means that if I am allowing the user to specify files to play I will have to find out the samples per second and bits per sample info before I can use the file.
I'd like to write an app that can send DTMF-tones during active voice calls. (Purpose: simplify usage of automated dialogs like "to listen to your messages, press 1. To do X, press 2", and so on)
I’m using lineGenerateDigits for this, but somehow it won’t work. This is my function:
Code:
long testSendTones() {
DWORD dwDigitMode = LINEDIGITMODE_DTMF;
DWORD dwDuration = 600;
LPCWSTR tone = TEXT("2"); // I’m not sure if this is correct
if (!g_hCall) {
// Error with the call
return -1;
}
long result = lineGenerateDigits(g_hCall, dwDigitMode, tone, dwDuration);
if (result) {
//error with digit gerneration
} else {
// everything ok
}
return result;
}
The result is that I don’t get an error (i,e. lineGenerateDigits returns 0), but I don’t get a tone either. The event “LINE_GENERATE” (is to get called after the tone is sent) is also triggered. So technically it all looks fine, but it just does not send the tone. I changed the tone duration to 0 and several other values, but it did not work.
Changing the digitmode to LINEDIGITMODE_DTMFEND yields a return value of 0x80000026 (LINEERR_INVALDIGITLIST), and produces no tone either.
Any suggestions? Any advice or idea is greatly appreciated.
