Why do you have _tmain and DllRegisterServer? _tmain is for .EXEs and
DllRegisterServer is for .DLLs. Which one are you trying to build?

Does your device have the MFC DLL installed?

First of all thank you all for your reply!

I have to create a Soft input panel, the reason why I would like to
have MFC included is,I have got source code for a Keyboard window CWnd
and its functionality, which I want to use. I have written some
applications including MFC statically linked - they run on my device.
I thought about creating a new dll, and included the above mentioned
code.
The book code contains a DLLmain function, the rest of the functions I
have included in my code, and there is a separate cpp and h file,
which is responsible for the window, (I thought replacing with my code
I already have):
code:
_____________
//
======================================================================
// DllMain - DLL initialization entry point
//
BOOL WINAPI DllMain (HANDLE hinstDLL, DWORD dwReason,
LPVOID lpvReserved) {
hInst = (HINSTANCE)hinstDLL;

return TRUE;
}_______________

The choice I mad for the dll was: new projekt Win32 Smart Device
Projekt -- DLL add
support for MFC. I got:

code:
________________________
int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
int nRetCode = 0;

printf("main");
// initialize MFC and print and error on failure
if (!AfxWinInit(::GetModuleHandle(NULL),
NULL, ::GetCommandLine(),
0))
{
// TODO: change error code to suit your needs
_tprintf(_T("Fatal Error: MFC initialization failed
\n"));
nRetCode = 1;
}
else
{
// TODO: code your application's behavior here.
}

return nRetCode;
}
____________________________________

Which project do I have to create?
What do I have to do?

Thank you for your help
Georg
