Hi,
Your query is not clear. but i think you want to start your camera. if yes then try this code.
Dim ccd As New Microsoft.WindowsMobile.Forms.CameraCaptureDialog
ccd.Resolution = New Size(100, 200)
ccd.Mode = Microsoft.WindowsMobile.Forms.CameraCaptureMode.Still
ccd.Mode = CameraCaptureMode.Still
ccd.Owner = Me
ccd.Title = "Take a Picture"
If ccd.ShowDialog() = Windows.Forms.DialogResult.OK Then
If ccd.FileName <> String.Empty Then
PictureBox1.Image = New Bitmap(ccd.FileName)
ccd.Dispose()
End If
End If
May be it helps you.
Thanks

Hi
Windows Mobile 5.0 Pocket PC Emulator does not provide the camera facility on the emulator. For debug your project on the Emulator you can use the Windows Mobile 6.0 Pocket PC Emulator.
May it solves your problem.
Thanks

I am developing a Windows Mobile 6.0 application. I need to make the application multilingual.. Is there any built in options available to change language as per our selection..
|
|
|
|
|
The language used on the device is selected through the regional settings. After that setting is changed the device must be reset for the change to take affect. Only then will you be able to see the change in the thread culture and UI culture.
|
|
|
|
|
I don't know on Windows Mobile if it works but in Windows Forms I do so:
System.Threading.Thread.CurrentThread.CurrentUICulture = New Globalization.CultureInfo(LangCode)
where LangCode is the language code you want to change in your application. (for example it-IT for Italian or en-US for english USA)
Hope this helps

Hi, everyone!
I'm writing a video player for Win Mobile...
Does anybody know which library should I use. Is there any library for unmanaged AVI handling using P/Invoke or high-level one with programmer-friendly interface. Some other ways, maybe (C# compatible only).
Looking forward to your answers...
|
|
|
|
|
I don't know of anything that was designed for managed developers, but for native developers there's DirectShow and of course embedding the Windows Media Player control.
|
|
|
|
|
Is there any possibility to use DirectShow in my c# code and if there is, can you explain how to do it?
|
|
|
|
|
There's no intrinsic support. You are going to have to make use of P/Invoke.
|
|
|
|
|
thanks, I'll try this...
Don't you know if it's possible to use windows libraries (e.g. avifil32.dll) in windows mobile?

Hello!
I try to access a HID USB device with my PocketPC LOOX with integrated USB Host.
I already figured out - that I can get an handle to the device with -> FindFirstDevice, FindNextDevice
I am quite sure I got the _right_ device, because I looked at the enumeration before an after I plugged it in.
The device name in the DEVMGR_DEVICE_INFORMATION is HID1.
I assume this also means the HID driver was loaded.
To make sure opening is made with the correct options - I do a
HANDLE hFile = CreateFileW(di.szDeviceName,
GENERIC_WRITE | GENERIC_READ,
FILE_SHARE_READ|FILE_SHARE_WRITE,
(LPSECURITY_ATTRIBUTES)NULL,
OPEN_EXISTING,
0,
NULL);
No error occurs, and I see a value for hFile.
Now I try to write and read from the handle with
...
Result = WriteFile(handle, &WriteBuffer, 10, &BytesWritten, NULL);
...
or
ReadFile(handle, &ReadBuffer, 10, &NumberOfBytesRead, NULL);
of cource with the right Buffer / Bufferlenght handling.
WriteFile and ReadFile does not work an come with error 50 (ERROR_NOT_SUPPORTED).
Does not seem right
So I tried to deal with DeviceIoControl .. and got no luck.
On Windows XP everythink work fine (HidD_GetPreparsedData, HidP_GetCaps, SetupDiGetClassDevsW, SetupDiEnumDeviceInterfaces, SetupDiGetDeviceInterfaceDetailW, CreateFile, ReadFile, WriteFile) but this functions does not seem to be available in Windows Mobile 5.0 (hid.dll, hidsdi.h, setupapi.h ...)
If you wonder which device I want to control ... here you go .. JoyWarrior 24F8 from www.codemercs.com
Can anyone point me to the right function to access / read / write an HID USB Device in Windows Mobile 5.0.
It does not matter if VB, VC++,C or C#

I’m trying to use the green TALK button on my Pocket PC as a floor control button. That means I need to know when the user presses it and when they release it.
I’ve found several ways to be informed when the user presses the VK_TTALK button, and I’ve been able to take control of the association with the default phone application (details below if you care to see them). The problem I’m having is determining when the user releases the button.
What happens is, no matter how long I hold the button down, I get a WM_KEYUP for VK_TTALK within a few hundred milliseconds of the key press event. This happens even though I hold the button down for many seconds after pressing it. (I see that this gentleman appears to have faced the same or a very similar issue.)
Can anyone tell me if there’s a way to do this? I’m beginning to think maybe it’s just a problem with the 6700 hardware or firmware. Or maybe it’s a more widespread issue? Any other ideas?
By the way, it happens that I’m working on an HTC6700, but I really need a portable solution that will work on any Pocket PC. A 6700-specific solution – though it might be cool and fun – really won’t help me. My environment, BTW, is C++ in MS Visual Studio 2005.
Approaches I’ve tried:
- SHCMBM_OVERRIDEKEY – I’ve used SendMessage(… SHCMBM_OVERRIDEKEY, VK_TTALK, …), as described here, to request that TALK button events be passed to me as WM_HOTKEY events.
- What worked: The built-in phone app launch was bypassed, so that’s good. And I did get WM_HOTKEY events for the button presses.
- What didn’t work: I got WM_KEYUP events telling me the user had released the TALK button, but they came way too soon, while I was still holding the button down.
- UnregisterFunc1(), UnregisterHotKey(), RegisterHotKey() – There’s a lot of discussion (here and here, e.g.) about this option. I’ve tried it and had problems similar to the ones I describe above.
- What worked: I avoided the phone app launch, and I did get WM_HOTKEY events for presses (and releases, too, if I recall correctly).
- What didn’t work: But the release events came too soon, as they did elsewhere. Also, after I exited my application, the connection between the TALK button and the built-in phone application was still broken. There’s probably a way I could restore that, but since the release events were no good, I doubt I’ll pursue this option.
- SHSetAppKeyWndAssoc() – I had high hopes for this one (described here), and it did let me grab keys other than VK_TTALK, but I wasn’t able to get VK_TTALK with it at all, and even with the keys I could get, I didn’t see any notice of key release events.
- SetWindowsHookEx() – I found some documentation of how to add a hook for low-level keyboard events (see here, e.g.) and tried it. I got the events, but they behaved just the same as SHCMBM_OVERRIDEKEY above. That is, I was told the button was pressed, and then told a too-short time later that it was released (when I was still holding it down).
- GetAsyncKeyState() – I even considered polling methods. I thought maybe I could start with one of the above methods, which at least notified me on the button press, and then poll to watch for the user to subsequently release the button. GetAsyncKeyState() is supposed to tell you whether a given button is down or up. And it did correctly report the button as being pressed when the event came telling me that it was pressed. But when a subsequent event came telling me (incorrectly) that it had been released, GetAsyncKeyState() ALSO told me the button was not pressed. So that’s no help.
I’m running out of ideas. How about you?
Thanks for any guidance you can provide!
Steve

i have a hunch that the device is using a short and long key press functionality IE tap a key for one function and hold for another.
it appears that once the timer for the held key is reached the WM_KEYUP msg is sent by default.
u may have to override the standard key handling functions at a lower level than u are currently interfacing to. unfortunatly i dont have the experince to point to a document that is helpful.

...a good thought. Thanks.
Sadly, when I check out this idea I find that no message at all comes to my hook when I actually release the button. You're right, of course, that sometimes you'll see differences between press-release and press-hold: say, one key code for a press-release and a different key code for press-hold. But in this case it's the very same key code in both cases, both event (KEYDOWN and KEYUP) are driven by the press of the key, and there's no event at all on the release of the key. Bummer.
And you may be right that I'll need to intervene at an even lower level then the "low-level keyboard events" hook I've got. I've not found a (portable) way to do that just yet, though.
And as it happens we've decided to move away from depending on the SEND key and let the user choose a key that works - whatever key that may be on their given device. So if this behavior does turn out to be peculiar to the 6700 - as the evidence currently suggests - then the user can just choose a different key on that device.
Thanks again for your idea.
Steve

sounds like a very sensible work around, otherwise you would have to find the function that posts WM_KEY msgs rewrite it, tie ur on keyhandler when ur app starts then tie the normal handler when ur app exits.... messy and would prob interrupt other functionality with the device =(

Hello,
I was wondering if anyone knows an alternative to receive sms to a personal computer other than through a GSM Modem. I really find this method quite slow than using kannel project.
Any reply would be greatly appreciated. Thanks in advance
