What is the type of pp.device?

You can look at:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wcecomm5/html/wce50conCOMPortEmulationFacility.asp
The type is BD_ADDR, they're the same type, so I don't understand the error.
Maybe this help (the web above) is for Windows CE and I'm developing for Windows Mobile 2003 SE, with the following software:
- Embedded Visual C++4 and his service pack 4.
- Microsoft Pocket PC 2003 SDK.
Could it be a problem? Can I develop an application for "making a virtual serial port" via bluetooth with this software?
Thanks in advance.

Javier

Hi,
Maybe it's too late,but take a look on "Bt_api.h" and you will see that the type of pp.device is not BD_ADDR - but BT_ADDR.
anyway - i have the same problem:
i need to set up BlueTooth comunication between my PDA and another device
and i want to use a virtual COM port,but i can't create one.
my problems are:
1.i can't convert BD_ADDR to BT_ADDR.
2.i can't find the device dll.
can you help me?
Best regards,
Eli

Hi, not sure if I undertand very well your question...
But if you are asking how to communicate in BlueTooth using a virtual COM port, it is in fact exactly the same than using a standard COM port. You open it with CreateFile (providing the correct Port name) and then you send/receive data using WriteFile/ReadFile functions.
If this was not what you were asking for, try to be more precise in your question.
Hope this helps

Hi There,
I'm using eVC 4.0 and have the Visio 2000 version. I need to document my
program, so I thought that Visio was the right tool and I thought that it
would be an easy task for Visio to read the source code and automatically
create the UML class diagram like it is with the "normal" Visual C - but...
I can't find a way to do it! Are there anyone who will be able to give me a
good advice or who knows how to document ones progream in an easy way - I
highly appriciate any help!
Regards,
siva

If I have a application for pocket pc 2003, and I want to run in pocket pc 2003 emulator, how do I do?
|
|
|
|
|
If you are making an application in "Microsoft embedded Visual C++" you can test it in the emulator compiling it and targeting the project to the emulator (maybe first you must configure the emulator connection in "tools->configure platform manager" menu).
If you have an executable application and you want to download it to the emulator you must configure the "active sync" program to emulate that "pocket PC Emulator" is a real device connected to the PC. In the "Microsoft embedded Visual C++" Help explain how to do it, but I try it once I couldn't (you must configure the emulator connection with active sync in "tools->configure platform manager" menu and so on).

Javier

I am writing for PocketPC 2002 using Embedded Visual Tools 3.0 (EVT3.0). The on-line documentation for CFile::Write() says "Write throws an exception in response to several conditions, including the disk-full condition." When I compile a try{ cfile->Write(...) } catch{...} code segment, the compiler flags the first of several cfile->Write() statements with: "... warning C4530: C++ exception handler used, but unwind semantics are not enabled. Specify -GX". My problem is where to insert this switch in the EVT3.0 environment?
I've found prerelease MSDN documentation on Structured Exception Handling <http: msdn.microsoft.com="" library="" default.asp?url="/library/en-us/dv_vccelng4/html/elgrfStructuredExceptionHandling.asp">, which says "Structured exception handling works with C and C++ source files. However, it is not specifically designed for C++. Although destructors for local objects will be called if you use structured exception handling in a C++ program (if you use the /GX compiler option), you can ensure that your code is more portable by using C++ exception handling. The C++ exception handling mechanism is more flexible, in that it can handle exceptions of any type." BUT, I think they're referring to Visual Studio 5 or 6, which has a slightly different Project interface than EVT3.0.
I also get the following linker errors due to the try/catch segment:
"error LNK2001: unresolved external symbol "const type_info::`vftable'" (??_7type_info@@6B@)
error LNK2001: unresolved external symbol ___CxxFrameHandler"
Does anybody know how to make EVT3.0 happy here?
Thanks

You don't because eVC++ 3.0 does not support C++ exceptions, only structured exceptions.

Thank you in anticipation!

 Unable to make a working pluggable MIME Filter on SPV E200 (Smartphone 2003) using eVC++ 4.0.
Everything seems OK :
CAB download and installation
Registry settings
The browser recognizes the content type and find that it is filtered (no "unknown content type" message) but the screen stays white and the browser seems to be in a loop : must be killed manually.
Anybody with similar experience ?

eVC3 targets Windows CE 3.0 (Pocket PC 2000 / 2002)
eVC4 targets Windows CE 4.x (Windows Mobile 2003)
eVC4 also supports C++ exceptions, RTTI and has better support for templates.

Hey All,
I would like to be able to access functions within an application extension on my pocket pc.
Specifically, I have an HP Photosmart Mobile Camera and would like to write a VB app that does the following:
I click on a button on my form and then the program captures an image.
I noticed a couple of application extensions in the Windows directory of my pocket pc...
