Re: Working with BlueTooth

10-Jun-03 2:27

Hello!

I need my Pocket PC to receive data over the BlueTooth link. How can I do to open the port and work with it ? I suppose I can open it with CreateFile and providing a name like "COMx", but where can I find the port number ??

I also 'coupled' my Pocket PC with my computer.
Any idea ?
Thanks

Normaly there is a configuration tool for the Bluetooth port on your Pocket PC where you can assign a virtual com port (eg. COM8) to your Bluetooth port.

Go to the registry and look for this key:

HKEY_LOCAL_MACHINE\ExtModems\BtDialupModem

Under it, you will find a Port value. This is the file name you must use when communicating with your phone. In my case it reads BTC1:

UNICODE convention

Hello,

I'm using eVC++ 3.00 and I want to do such a thing:

MessageBox("Test");
But I'll have an error at compilation:
error C2664: 'MessageBoxW' : cannot convert parameter 1 from 'char [29]' to 'const unsigned short *'

So, it's because UNICODE convention is used as standard. I suppressed it from the preprocessor settings but it still doesn't work! Is ANSI convention not supported ??

Thanks

Windows CE only supports UNICODE. All MFC methods and API functions and messages (with some notable exceptions) take UNICODE text. So, your code MUST read:

MessageBox(_T("Test"));

That's it

!! This will give me a lot of work to convert my existing library Frown | :-(

!

Is there a simple way to convert ANSI string to UNICODE string?

char Buff[255];<br />
...<br />
...        // Do some stuff with Buff<br />
...<br />
MessageBox(Buff);    // Need conversion here !!

Thanks

The best thing for you is start replacing char with TCHAR. If you want to do UNICODE to ANSI on-the-fly conversions, your application will run slower. But if you insist, use the mbstowcs, mbtowc, wcstombs and wctomb (check these out from the online help).

On PocketPC 2002, I write an application like Ms PocketStreet. I have a toolbar’s icon (called A). When I press onto this icon (A), I can zoom IN a map in screen. Now, I want this: when keep pressing onto a key (like Alt or Ctrl or Shift on Desktop), and press onto icon A, I can zoom OUT the map. It works as Photoshop did.

How can I solve this problem. I saw in PocketPC 2k2, there’re 4 buttons in the bottom of it. I wonder if whether there are some Alt-on-desktop-like buttons or not.

Help me.

You can actually use the hardware buttons. Check this page for guidance:

Can you tell me how many hardware keys are there in PPC 2002 ? I knew that there're only about 5 hardware buttons in PPC 2k2 (in the bottom of the device).

But when I read about RegisterHotkey, it show a range from 0x0000 to 0xbfff !!! What is Identifier of 5 buttons on the device ? I want when keeping press into 1 of 5 buttons, then press into an icon on toolbar, my app will do something.

How to access memory details

My iPAQ 3850 (as well as series 39xx) has 5 hardware buttons plus the central oval button that emulates the 4 arrow keys and enter.
