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.

 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...

Do you know what the function signatures are?

Hi all,
I am developing a PPC application. I want to use RDA with MSDE database.
I cant find sscesa20.dll on my PC (maybe because I dont have SQL CE Server Agent installed )
I heard around that I only need sscesa20.dll for RDA.
Please correct if I am wrong. And tell me a way to find this dll without installing something.
Thanks in advance.

Yes, you do need sscesa20.dll for RDA.

I dont know the CDIBSectionLite class , but it seems to me you forgot to link to a library (in Project\Settings )
or (not likely but possible) maybe you forgot to add the .cpp file to your project??
Hope this helps you some...

Hi, I'm using the CbitmapButton class in a dialog box. When I use the "AutoLoad" member to load the bitmaps, it's works ok. Is there a way to use the "LoadBitmaps" member instead "Autoload"?? (I have read in the help that "loadBitmap" can be used only under a window, not for in dialog use).
I try it and using "LoadBitmaps" it doesn't paint the bitmaps:
// Create a push button.
m_MyBOTON.Create(NULL, BS_PUSHBUTTON|BS_OWNERDRAW, CRect(100,100,100,100), this, IDC_MYBOTON);
m_MyBOTON.LoadBitmaps(IDB_UP, IDB_DOWN, 0, 0);
Thanks in advance.
Regards,
Javier.
