Turn ON/OFF BT/Widcomm on BA with eVc

Does anyone know how to turn on and off the Widcomm bluetooth on a Blue Angel from within C/eVc? :?:
tia

The only official way to turn off the radio is to destroy the last of the BT objects using the stack (the stack is object orientated, creating an object turns it on, destroying the lst object turns it off, this assumes you have the widcomm SDK). The problem is that the BT app that runs in the system tray (and shows you that bluetooth icon in the bottom left) owns a stack object that you cant properly destroy, hence you can't turn the radio off.
hrm...
If the tray app wasn't running, theres a function in the wbtapiCE.dll called UnloadStack ([email protected]@@[email protected]@[email protected]) which should force the stack to unload and probably turn off the radio.

So we might be able to turn it OFF this way. And how do we turn in ON again ;-)

Theres a corrasponding LoadStack ([email protected]@@[email protected]@[email protected]) which would do the job.
Each of these accept two parameters, the first appears to be a pointer to a class, the second a numeric value.
For the class pointer, it appears that you can define an 8 byte array and call the constructor ( [email protected]@[email protected] ) on it, remember to call the destructor ( [email protected]@[email protected] ) when your done. The hex value appears to be 0x123456 for LoadStack and 0x654321 for UnloadStack.
I really don't know how successfull you would be starting the stack yourself, spinning up the BT tray app, then killing it and shutting down the stack, you may find you have to replace all the functionality of the tray app yourself.

Complicated stuff. I might be easier off doing FindWindow on the BtApp and find the ON and OFF buttons and programatically press them.

Hello All.
I call wbtapiCE.dll functions for on/off BT on dell axim x30.
I use, two dll metods
[email protected]@@[email protected]@[email protected] == public: enum WBtRc __cdecl CWBtAPI::UnloadStack(unsigned int)
and
>> [email protected]@@[email protected]@[email protected] == public: enum WBtRc __cdecl CWBtAPI::LoadStack(unsigned int)
But no positive effect.
Anybody know what i doing wrong?
Sample code below:
{
CString szDllPath = _T("wbtapiCE.dll");
HMODULE hMod = LoadLibrary(szDllPath);
if(hMod==NULL)
{
AfxMessageBox(_T("LoadLibrary Failed !!!"));
}
//__cdecl CWBtAPI::CWBtAPI(void)

CWBtAPI* a1 = (CWBtAPI*)_alloca(sizeof(CWBtAPI));
PFNCreateCWBt pfnCreateWBt = force_cast<PFNCreateCWBt>(GetProcAddress(hMod, TEXT("[email protected]@[email protected]")));
(a1->*pfnCreateWBt)();
//////////////////////////////////////////////////////////////////////////

AfxMessageBox(err );
//////////////////////////////////////////////////////////////////////////

/*************************************************************************/
FreeLibrary(hMod);
}

could some kind soul maybe write a script to do someth like that...

I make it BT on/off
Jn dell axim X30 exist btpwr.dll.
This dll export some interesting methods.
1 0 0000128C PowerDeInit
2 1 00001284 PowerInit
3 2 00001258 PowerOff
4 3 0000121C PowerOn
I call this methods directly from dll, and i turn on turn off bt !!
Sample code below:
void DoTrayOn()
{
CString szDllPath = _T("btpwr.dll");
HMODULE hMod = LoadLibrary(szDllPath);
if(hMod==NULL)
{
AfxMessageBox(_T("LoadLibrary Failed !!!"));
}
typedef int (*BTPowerOn)();
BTPowerOn bton = (BTPowerOn) GetProcAddress(hMod, TEXT("PowerOn"));
if (NULL != bton)
{
// AfxMessageBox(_T("Start DoTrayOn"));
(bton) ();
}else
{
// AfxMessageBox(_T("Error NULL DoTrayOn pointer"));
}
FreeLibrary(hMod);
}
void DoTrayOff()
{
CString szDllPath = _T("btpwr.dll");
HMODULE hMod = LoadLibrary(szDllPath);
if(hMod==NULL)
{
AfxMessageBox(_T("LoadLibrary Failed !!!"));
}
typedef int (*BTPowerOff)();
BTPowerOff bton = (BTPowerOff) GetProcAddress(hMod, TEXT("PowerOff"));
if (NULL != bton)
{
// AfxMessageBox(_T("Start DoTrayOn"));
(bton) ();
}else
{
// AfxMessageBox(_T("Error NULL DoTrayOn pointer"));
}
FreeLibrary(hMod);
}

Bluetooth turn on/turn off
Hello
Have you a solution for turn on and turn off bluetooth by code?
I have a widcomm stack and I use c# .net

i'm searching for a solution for my Touch Pro 2 with Widcomm BT Stack.
i can turn on BT by creating an object of CBtIf, but can't turn of BT by deleting the object.
someone has an idea?

Programmatically cycle sound icon (sound/vibrate/mute)

When you click on the sound icon, you get the two sliders and three radio buttons. Anyone know how to set those radio buttons through code (C++) so it gets reflected in the icon display (and actually changes the "profile")?. I'd like to change to vibrate/mute/sound at different times using something like alarmToday to run a small app.
Thanks,
sbl

I wrote a profiles app in .net and C++ here are some code snippets;
You can change the registry values for the volumes (I cant remember which as I wrote it a long time ago), then you need to call the following to have the values applied.
// ProfilesHelper.cpp : Defines the entry point for the DLL application.
//
#include "stdafx.h"
#include "ProfilesHelper.h"
#include <windows.h>
#include <Soundfile.h>
void WINEXPORT SetSoundMode(int mode)
{
// Initialize an empty SNDFILEINFO structure
SNDFILEINFO sndfile = {0};
if (mode == 0)
sndfile.sstType = SND_SOUNDTYPE_ON;
if (mode == 1)
sndfile.sstType = SND_SOUNDTYPE_VIBRATE;
if (mode == 2)
sndfile.sstType = SND_SOUNDTYPE_NONE;
SndSetSound(SND_EVENT_ALL, &sndfile, false);
void AudioUpdateFromRegistry();
}
void WINEXPORT SetSystemVolume(long volume)
{
waveOutSetVolume(NULL, volume);
void AudioUpdateFromRegistry();
}

Hi,
I have a similar need of programatically cycling the sound icon to MUTE VIBRATE and normal volume icon. I can do it successfully on Windows Mobile 5.0. I created a sample application with Visual Studio 2005 for WM 5.0 and I am able to set the icons as i want. But when i tried it for PPC2003 I was not able to compile that. Missing SoudFile.h. Can any one help me to find out how to do the same thing on PPC2003 specifically i-mate devices like PDA2 and PDA2K.
Thanks
With Regards,

i know its a 2 ur old post..but i need help also now
how can i mute sounds using C# in .net 2.0 for WM6

Just forget about this header file...
Operate on HKCU\ControlPanel\Notifications\ShellOverrides\Mode value. It can have 3 states: 0 == normal, 1 == vibrate and 2 == silent. That's all
Probably you need to call AudioUpdateFromRegistry function from coredll.dll.

Or... another method
look at HKCU\ControlPanel\Sounds\RingTone0:Sound, it takes 3 different values:
*none*
*vibrate*
your ringtone name, taken from SavedSound value in the same key.

Hi,
Firstly I know this post is way old, but I thought of responding to it since I was stuck on this topic for a couple of days and couldnt find a way to resolve it.
Also others having this problem will also be redirected here through various search results as I was. So to aid them
1. Meddling with the registry to change the sound profiles didnt work for me. I tried Changing the Mode inHKCU\ControlPanel\Notifications\ShellOverrides\Mode but that didnt work on my phone.
2. What I currently have working is the following code - C# with Pinvoke
public enum SND_SOUNDTYPE
{
On,
File,
Vibrate,
None
}
private enum SND_EVENT
{
All,
RingLine1,
RingLine2,
KnownCallerLine1,
RoamingLine1,
RingVoip
}
[StructLayout(LayoutKind.Sequential)]
private struct SNDFILEINFO
{
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 260)]
public string szPathName;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 260)]
public string szDisplayName;
public SND_SOUNDTYPE sstType;
}
[DllImport("coredll.dll")]
public static extern void AudioUpdateFromRegistry ();
[DllImport("aygshell.dll", SetLastError = true)]
private static extern uint SndSetSound(SND_EVENT seSoundEvent, ref SNDFILEINFO pSoundFileInfo, bool fSuppressUI);
static void SetProfileNormal()
{
SNDFILEINFO soundFileInfo = new SNDFILEINFO();
soundFileInfo.sstType = SND_SOUNDTYPE.On;
uint num = SndSetSound(SND_EVENT.All, ref soundFileInfo, true);
AudioUpdateFromRegistry();
}
static void SetProfileVibrate()
{
SNDFILEINFO soundFileInfo = new SNDFILEINFO();
soundFileInfo.sstType = SND_SOUNDTYPE.Vibrate;
uint num = SndSetSound(SND_EVENT.All, ref soundFileInfo, true);
AudioUpdateFromRegistry();
}
static void SetProfileMuted()
{
SNDFILEINFO soundFileInfo = new SNDFILEINFO();
soundFileInfo.sstType = SND_SOUNDTYPE.None;
uint num = SndSetSound(SND_EVENT.All, ref soundFileInfo, true);
AudioUpdateFromRegistry();
}
Hope this helps

GPS Intermediate Driver parsed API - in VB?

Is anyone currently using the GPS Intermediate Driver parsed API in VB?
I'm looking to get started but needing a bit of a kick-start. I've found the API to be used and it seems simple enough with only 4 functions but I don't see an example of anyone using it in VB, anywhere...
From the example in C++ from the SDK the DLL has the following functions but I don't know how to convert to VB, can anyone give a hand?
#region PInvokes to gpsapi.dll
[DllImport("gpsapi.dll")]
static extern IntPtr GPSOpenDevice(IntPtr hNewLocationData, IntPtr hDeviceStateChange, string szDeviceName, int dwFlags);
[DllImport("gpsapi.dll")]
static extern int GPSCloseDevice(IntPtr hGPSDevice);
[DllImport("gpsapi.dll")]
static extern int GPSGetPosition(IntPtr hGPSDevice, IntPtr pGPSPosition, int dwMaximumAge, int dwFlags);
[DllImport("gpsapi.dll")]
static extern int GPSGetDeviceState(IntPtr pGPSDevice);
#endregion
Thanks,

can you post the c++ code here. we can try and rebuild the data structures for vb which would allow you to execute the dll functions. (I would od it but I'm at work, not access)

How much of the code are you interested in?
In case anyone is interested I was able to find an unwilling soul to convert the first signature.
Here is the signature in C#:
[DllImport("gpsapi.dll")]static extern IntPtr GPSOpenDevice( IntPtr hNewLocationData, IntPtr hDeviceStateChange, string szDeviceName, int dwFlags);In VB, it looks like this:
In VB:
<DllImport("gpsapi.dll")> _Function Shared GPSOpenDevice( _ ByVal hNewLocationData As IntPtr, _ ByVal hDeviceStateChange As IntPtr, _ ByVal szDeviceName As String, _ ByVal dwFlags As Integer) As IntPtrEnd Function
hopefully some others can help come up with some simple VB source for using the GPS device....

Well I've made a little progress but once again I'm stumped since I don't program in C..
Currently I'm able to open and close the GPS device on my phone but in order to retrieve information I believe I need a stuct converted to VB. I'm not familiar with struct so I'm hoping someone can explain it to me and or maybe help convert it.
These are the functions that have been converted to VB from C:
'Put this at the top of your module.
'Required in all cases when calling API functions
Imports System.Runtime.InteropServices
'Required in this example and any API function which
'use a string buffer. Provides the StringBuilder class
Imports System.Text
Public Class Form1
<DllImport("gpsapi.dll", EntryPoint:="GPSOpenDevice", SetLastError:=True, CharSet:=CharSet.Unicode, CallingConvention:=CallingConvention.Winapi)> _
Public Shared Function GPSOpenDevice(ByVal hNewLocationData As IntPtr, ByVal hDeviceStateChange As IntPtr, ByVal szDeviceName As String, ByVal dwFlags As Integer) As IntPtr
End Function
<DllImport("gpsapi.dll", EntryPoint:="GPSCloseDevice", SetLastError:=True, CharSet:=CharSet.Unicode, CallingConvention:=CallingConvention.Winapi)> _
Public Shared Function GPSCloseDevice(ByVal hGPSDevice As IntPtr) As Integer
End Function

Public Shared Function GPSGetDeviceState(ByVal pGPSDevice As IntPtr) As Integer
End Function

and this is the struct I need help with:
typedef struct _GPS_POSITION {
DWORD dwVersion;

DWORD dwValidFields;
DWORD dwFlags;
SYSTEMTIME stUTCTime;
double dblLatitude;
double dblLongitude;
float flSpeed;

DWORD rgdwSatellitesInViewAzimuth[GPS_MAX_SATELLITES];
DWORD rgdwSatellitesInViewSignalToNoiseRatio[GPS_MAX_SATELLITES];
} GPS_POSITION, *PGPS_POSITION;
Click to expand...
Click to collapse
I think the struct works like some type of callback which even that I'm not familiar with but as you try and retrieve information from the function 'GPSGetPosition' it uses the struct to do the work? just a guess...
Anyway I'm hoping someone can help me out as I feel I'm close but unless I can pull GPS data at still at ground zero...
TW,

Simple solution: Compile C# (this is NOT C+++) code to dll library. Then reference library from VB.NET solution.
C# and VB.NET are compiled both to IL.
Here is the needed code and declarations in C#.
<Your path>'Windows Mobile 6 SDK\Samples\PocketPC\CS\GPS\GpsPosition.cs"

Since I'm a bit green - are there some examples of doing this somewhere that I can take a look at?
"C# and VB.NET are compiled both to IL."
I don't follow what your saying here? what does IL stand for?
Thanks,

My friend,
why sample?
IL = Intermediate Language - VB.NET and C# are compiled to intermediatate language.
.Net Framework is languaage independent - You can compile C# code to dll and then reference (add reference) this dll in VB.NET project and use types form C# dll directly.

Thanks, I certainly appreciate your patience...
OK, I'll remember to use VB.NET as opposed to .NET in the future since there is a difference that I was unaware of, thanks for that.
Since I want to run this application on my phone I assume I need to create a new project in VB.Net - WM6 class library. Can I simply copy over the references and source form the original SDK and then build the .dll from there or am I over simplifying?
After building the .dll, in the application I want to create I make the reference to the new .dll, got it, when I want to reference the struct of the 'GPSGetPosition' function how would I do that?
TW,
[EDIT]
Doing more reading and learning a bit.
I think using a dll is the way to go and I believe there is a dll included in the sample. That brings me back to the Q of implementation. I've added a reference to the dll but since I'm only using the functions built within the dll how should I pass the GPS_POSITION struct listed above? does that still need to be converted to VB.Net then passed?
Semi manual marshhalling of structure to pointer:
Dim pointerM As IntPtr = Marshal.AllocHGlobal(Marshal.SizeOf(myStruct))
Marshal.StructureToPtr(myStruct, pointerM, False)
Marshal.FreeHGlobal(pnt)
Click to expand...
Click to collapse
Since the above doesn't seem to pass anything to the struct is this used for sizing the struct to be passed?

OK.
Here is the compiled dll.
Add reference from vb.net project to dll.
Then (conceptual code in the pretty poor verbose VB.NET syntax )
Dim gps As new Gps()
AddHandler gps.DeviceStateChanged , DeviceStateChanged
AddHandler gps.LocationChanged, LocationChanged
gps.Open();
Public Sub LocationChanged(sender As object, args as LocationChangedEventArgs)
'Do something
args.Position.LatitudeInDegreesMinutesSeconds
args.position.LongitudeInDegreesMinutesSeconds
End Sub
Public Sub DeviceStateChanged(object sender, DeviceStateChangedEventArgs args)
'Do something
//GPS driver state
args.DeviceState;
End Sub
End of work with gps:
gps.Close()

//edit: Remove zip extension from gps.dll.zip - gps.dll is a valid name of assembly

RStein,
Thanks for your help. I managed to get it going with your assistance, it's much appreciated.
The .dll you compiled is not complete and errors though..

Dlli is a complete - from gps managed sample.
What's the error You're talking about?
As I said in other zda thread - intermediate driver doesn't work correctly on some Devices/ROM because of the error in the Microsoft/OEM implementaton (Htc Artemis).. http://groups.google.com/group/microsoft.public.pocketpc.developer/msg/2cedd69b906d4b7e
And finaly - GPS intermediate must be of course active in the control panel.

This is the error generated:
System.MissingMethodException was unhandled
Message: File or assembly name 'Microsoft.WindowsMobile.Samples.Location, Version=1.0.2985.26108, Culture=neutral, PublicKeyToken=null', or one of its dependencies, was not found.

Thx,

Please rename gps.dll to Microsoft.WindowsMobile.Samples.Location.dll

And here is the project in VB - functional

I'm using VB.Net for Windows Mobile 5, but still not working
I want to use the GPS Intermediate Driver because I want to let the GPS to be used for other apps, such as the Google Maps for WM and other.
I did the following code, but I still not getting the right result... I did a program using the Serial connection, but Google Maps and other cannot use the GPS at the same time.
So... what am I doing wrong?
Here my code, any clues?

Thank your for the GPS Vb.Net Sample
Hi René,
Your sample help me a lot, but I still have some issues and I hope you can give me more clues.
During my tests... everything works fine, but when I tried to use some of the date from LocationChanged, it do not return data. The GPS icon is GREEN, so, it's looks like everything is fine... the Google Maps works with my apps to, but all return ""
frmPrincipal.lblLatitude.Text = e.Position.Longitude.ToString()
frmPrincipal.lblLongitude.Text = e.Position.Longitude.ToString()
frmPrincipal.lblAltitude.Text = e.Position.SeaLevelAltitude.ToString()
Other thing... why at DeviceStateChanged the only way to get data if with a INVOKE like you did?
Invoke(New UpdateDataHandler(AddressOf AddItem), e.DeviceState.FriendlyName)
And final...
As I can see... the LocationChanged, is not so acured... because it was been called every second or less... it's normal?
Best,
Ruben

Getting a error with GPS
I'm getting the following error. I get this random, as I read, the GPS API uses a file to get it's info, so... I thing could be it.
gps.GetPosition.SatellitesInViewCount.ToString Run-time exception thrown : System.IO.IOException - The process can not access the file '\Test.txt' because it is being used by another process.
With the Debug, I have the following info:
gps.GetDeviceState.FriendlyName ""
gps.GetDeviceState.DeviceState On {1}
gps.GetDeviceState.ServiceState On {1}
gps.Opened True
And the error showed it self, when I use any of the follow properties:
gps.GetPosition.LatitudeValid
gps.GetPosition.SatelliteCount
gps.GetPosition.Latitude
I saw at my PDA root folder a Test.txt and also I read that file could configured with.
http://msdn.microsoft.com/en-us/library/ms889970.aspx
Some one have any clues?
I'll continue to dig... if I post here if I get more info.
I'm using a Windows Mobile 5 the HP 6945.

With this DLL work on all device????
I made an application named "Where is" and i use the Serial Port to check the info from GPS but in some device i cant get the data and i dont know why.
With this DLL i can resolve all problems?
I work with vb.net.
Wait an answer please.
Bye

I'm using evc4, so I can't build for a THUMB ( wince 5.0 ) device... any way you can recompile the lib for ARMv4?
Otherwise, I'm still linking w/ the Vincent lib.
Anyway, I started a whole new app ( appwizard hello template ) instead of writing the winmain from scratch and I still cannot generate a surface when I have anything but EGL_NONE in the config requests.
One thing I note is that fps is about 47-48, but once again, the texture is not mapped onto the object. If I put it in my folder w/ the Vincent dll, the texture is mapped and the fps is about 11-12.
I'm not quite familiar w/ EGL, but... does anyone know the EGLConfig structure? I tried searching for it to see what the requested width/height per config was so I can debug why the surface just doesn't get created.
anyway, here's my code:

That's ARMv4 or ARMv4i? I'm going to assume latter because that's what most of the dlls seem to be targeting. I'll put this up soon.
Meantime, GetClientRect() on your hwnd and make sure the rect is sane before you pass it on to eglCreateWindowSurface().
Also, Imageon may work better with GLfloat values although it probably kills Vincent (with software emulation on the ARM without native FP support in armv6 by the compiler) with anything but GLfixed. Try some benchmarking to see which works out better.

100000xtimes thanks!

can you make a sourceforce project??

ARMv4 is what evc4 targets...
GetClientRect() is giving me very sane values, 268x240... 268 due to the bars up top & below.
I guess I'm just confused as to why Vincent is able to properly create the proper surface while our drivers cannot...
Edit:
//eglDisplay = eglGetDisplay(EGL_DEFAULT_DISPLAY);
eglDisplay = eglGetDisplay(GetDC(hWnd));
eglInitialize(eglDisplay, &majorVersion, &minorVersion);
eglConfig = select_config(eglDisplay, EGL_WINDOW_BIT, 16, 16, 4);
ctx = eglCreateContext(eglDisplay, eglConfig, NULL, NULL);
eglWindowSurface = eglCreateWindowSurface(eglDisplay, eglConfig, hWnd, NULL);
eglMakeCurrent(eglDisplay, eglWindowSurface, eglWindowSurface, ctx);

I just realized that you don't provide egl config attribs for for eglCreateWindowSurface or for eglCreateContext... huh. Doing that, the surface and context are created ok, but the texture still isn't loaded... mebbe a problem w/ texture loading.

Anywho, it looks like the problem w/ texturing is that our drivers do not seem to support mipmap. By commenting out the linear mipmap flag when loading the texture, we get a fully working opengl es test app. I get about 44 fps.
See for yourselves.
View attachment testapp2.zip
@nushrike, both of your libgles_cm.lib's are designed for the 'THUMB' device. It's ok. I'll just keep on linking to the vincent lib.
Just remember that our driver does not support mipmap.

I think it's eVC is too old then. It's been thumb since WinCE5. Most all the system libs I have to link to insiste on Thumb -- if I set it to ARM, it refuses to link. Hey, that's an idea.. I'll try ARM to see if it generates any .lib.
For hardware, or supported mipmapping (software or not), look up glGenerateMipmapOES(GL_TEXTURE_2D). The tech demo I posted earlier demonstrates this. It's that blurry looking rotating texture behind the checker-board and various other textures.
edit: nope, can't create a dummy .lib by trying to link ARM.
Instead, you can modify Vincent to fake-support the extended functions as you need them and as they exist in the HWA .dll exports list. Here's an example:
Code:
#ifdef __GL_EXPORTS
# define GL_API __declspec(dllexport)
#else
# define GL_API
#endif
#define GL_APICALL GL_API
#define GL_APIENTRY
#ifdef __cplusplus
extern "C" {
#endif
{
GL_APICALL void GL_APIENTRY glGenerateMipmapOES (GLenum target)
{ return; }
#ifdef __cplusplus
}
#endif

No code to make it a SourceForge project. Now, if it was code to make the drivers, that would be worthy.
ycavan: figured out your bug. You have to pass NULL for configAttrib (the last parameter) for eglCreateContext, and eglCreateWindowSurface. Also, using glGenerateMipmapOES(GL_TEXTURE_2D) with your source, texture works fine now. Same FPS. I'm seeing if converting to GLfloat will speed it up.
edit: float is no speed increase so far, but no decrease either.

How do you get this to run? I've already asked you in PM that WinCE doesn't support the concept of "current working directory" and you use in your code.

I'm sorry about not responding to the pm's... lol, I just didn't see them.
Anyway, just unzip the file on your pc and copy the exe and resources folder to your device and run the exe. Just make sure to keep the exe and resources folder together.

It doesn't work for me after I drop it into the "Program Files" folder because this code is hard-coded for root directory then.

really odd... i ran the program in its own directory w/o a problem... i'm @ work, so i'll check it out when i get home.
it looks like the "resources" directory must be on the root of the device...
I'm working on finding the cwd, but loading resources fails even though it's the correct wd...
You guys can try and see if this works...
Code:
TCHAR tPath[255];
char sPath[255];
// get full path to this executable
GetModuleFileName(NULL,tPath,255);
// find the last '\'
TCHAR* pos = wcsrchr(tPath,'\\');
// end the string after the last '\'
*(pos+1) = '\0';
// copy wide char array to multi-byte string
wcstombs(sPath,tPath,255);
sPath should contain the working directory... but my app is failing the resource loads even though this is the same full path as before...

this can be very intresting for xda flame with goforce? can you build the libs because there is no SDK avialeble, the test app doesn't work message:
OpenGL ES init error:
eglInitialize

EDIT:
Just realized that you're talking about another phone w/ the goforce... lol
You will need to prolly google "goforce opengl es sdk" There should be quite a few out there.
On another note... I figured out the problem with working directory resource loading.
I prefer to make a call once when it's something configuration-related... like storing my current working directory... it seems that evc4 doesn't like it when I do that so I had to update mesh.cpp and texture.cpp to perform the GetModuleFileName calls in each load function.
Here's an updated TestApp2. You just need to keep testapp2.exe and the resources directory together.
View attachment testapp2.zip
Updates include:
+ fullscreen now
+ up/down rotation
+ left/right acceleration -100 to 100
+ spouting of particles
Have fun guys.
The resources directory contains these files that you can change if you want to try different things.
spot.raw - the particle system's balls texture
font.raw - the font texture
knot.gsd - the main object mesh
fire128.tga - the mesh object's texture

lol for goforce there are none zero nada

[WM6] Disabling taskbar, SIP and hardware keys (including green and red buttons)

Hello there!
I've seen a lot of questions on this topic, and just yesterday, my client asked for this feature implemented in the app that we are currently developing...
After a veeeery intensive and long night, i finally found how to disable all these things! The code is written in c# using .net CF 2.0, and has been tested successfully on a HTC Tynt device. The interesting thing is that it will also disable the End Call and Make Call hardware buttons (VK_TEND and VK_TTALK). If you intend to use this in a production environment you might consider improoving it a little bit.

Very good, helped me a lot! But how do I unlock the keys again, without rebooting?
Thanks!

Hello there!
I've seen a lot of questions on this topic, and just yesterday, my client asked for this feature implemented in the app that we are currently developing...
After a veeeery intensive and long night, i finally found how to disable all these things! The code is written in c# using .net CF 2.0, and has been tested successfully on a HTC Tynt device. The interesting thing is that it will also disable the End Call and Make Call hardware buttons (VK_TEND and VK_TTALK). If you intend to use this in a production environment you might consider improoving it a little bit.
[DllImport("coredll.dll")]
private static extern bool UnregisterFunc1(KeyModifiers modifiers, int keyID);
[DllImport("coredll.dll", SetLastError = true)]
public static extern bool RegisterHotKey(IntPtr hWnd, // handle to window
int id, // hot key identifier
KeyModifiers Modifiers, // key-modifier options
int key //virtual-key code
);
public enum KeyModifiers
{
None = 0,
Alt = 1,
Control = 2,
Shift = 4,
Windows = 8,
Modkeyup = 0x1000,
}
private void DeactivateUI()
{
try
{
// deactivate the SIP button
IntPtr hSip = FindWindow("MS_SIPBUTTON", "MS_SIPBUTTON");
EnableWindow(hSip, false);
// deactivate the SIP button
IntPtr hTaskBar = FindWindow("HHTaskBar", null);
EnableWindow(hTaskBar, false);
// deactivate the hardware keys
for (Int32 iCounter = 193; iCounter <= 207; iCounter++)
{
UnregisterFunc1(KeyModifiers.Windows, iCounter);
RegisterHotKey(this.Handle, iCounter, KeyModifiers.Windows, iCounter);
}
UnregisterFunc1(KeyModifiers.None, 0x73); //VK_TEND
RegisterHotKey(this.Handle, 0x73, KeyModifiers.None, 0x73);
UnregisterFunc1(KeyModifiers.None, 0x72);
RegisterHotKey(this.Handle, 0x72, KeyModifiers.None, 0x72); //VK_TTALK
}
catch (Exception ex)
{
Log.WriteError(ex, false);
}
}
Cheers!

Implement code
Hello!
I have created app to WM 5 - 6.5, but users can close it using END button. I see your code, but i can't implement ( i mean I don't have sufficient knowledge) it to visual studio 2008.
Could you tell me what should I do?

Error 1 'APP.Kiosk' does not contain a definition for 'Handle' and no extension method 'Handle' accepting a first argument of type 'APP.Kiosk' could be found (are you missing a using directive or an assembly reference?)

Handle? wtf
