I have already added the dependencies in the dll properties. However I am not sure what you mean when you say "you will need to explicitly export all of the functions and variables from the various .LIBs, from the DLL". I export symbols (classes/functions) using dllexport in each project. Do you mean that I have to do anything more in the dll project? The fact is that without referencing a class from the dll project it will not be linked by the linker to the target dll. I am wondering if I can bypass this linker "optimization" and make the linker unconditionally add a class' code in the dll. Cheers, Themis

It could be that the original poster has used CreateThread rather than _beginthreadex. Using CreateThread does not initialise the C run-time's internal data structures for the thread, and is unsafe in C code unless you really know what you're doing. Using the C run-time DLL allows you to get away with calling CreateThread because it does the necessary initialisation in the DLL's DllMain routine, on receiving the DLL_THREAD_ATTACH notification. Stability. What an interesting concept. -- Chris Maunder

Yeap actually that was the case, I forgot to export the symbols. Thanks for the tip, I could have gone days without realizing it.

DLL A: BldT.h: template<class TT> class BldT {...}; typedef BldT<long> BldLong; #include "BldT.i" BldT.i: template<class TT> BldT<TT>::BldT( void ) {...} ... BldT.cpp: // The following will export all methods from BldT<long> template instance template class __declspec(dllexport) BldT<long>; DLL B: SBld.h class ScnBld : public BldLong {...}; You will still need to access BldT.h from DLL B to compile. However, you shouldn't need to provide BldT.i and can remove the #include "BldT.i" from the BldT.h that DLL B uses. ...cmk Save the whales - collect the whole set

Yes I just read my message in firefox (browser I use) and then reloaded it in IE (just because of curiosity) and saw that in IE code blocks are printed red and the rest black. However in firefox everything is printed in black until a code block begins, then everything below that point prints in red, even after the code block end. Anyway that just a note. Themis

Thank you all for you answers!

Your GetProcAddress on "fngreet" doesn't work because it's real name isn't fngreet, C++ uses decorated functions so you will get something different which will change if you add/remove arguments, change types. You can use Dependency Walker to see what the real name is and use that. It's recommended to use C linkage instead which will make your GetProcAddress work. Declare the function using extern "C". #ifdef GREET_EXPORTS #define GREET_API extern "C" __declspec(dllexport) #else #define GREET_API extern "C" __declspec(dllimport) #endif You cannot use GetProcAddress to return a class, however you can create a function which returns a class and use that function.

If the MyClass ctor/dtor have no code, and no other code references obj, then the linker will discard the global object because it's not being used. --Mike-- Visual C++ MVP :cool: LINKS~! Ericahist | 1ClickPicGrabber | CP SearchBar v2.0.2 | C++ Forum FAQ Wizard needs food, badly!

Here's a thought: 1) Create a user defined message, that you can post to display the dialog. 2) In the main frames OnSetFocus(), just post the message (post not send). If there is already a command that allows the user to display the dialog then you can skip step 1 and just post that messge.

Thanks I'll try that!

You can start from 'WCE Application' or 'WCE Pocket PC 2003 Application'. On the first page of the wizard, select 'A simple Windows CE application'. This generates a StdAfx.h for common includes and definitions, StdAfx.cpp (which causes precompiled headers to be generated for StdAfx.h) and project.cpp, which contains a WinMain routine. Pocket PC does not support the C standard main routine. The Windows CE C run-time library does not provide the mainCRTStartup routine that the desktop provides. You should use WinMain instead. Please be aware that Windows CE only supports a total of 32 concurrent processes - this is a consequence of the single-memory-map design. A number of those process slots are already running at startup time - the device driver host process device.exe, the Graphics Windowing and Events Subsystem gwes.exe, the file system process filesys.exe, and others. CE 4.x and later provide a Services host process for hosting services written as DLLs. Stability. What an interesting concept. -- Chris Maunder

I'm surprised that they've shipped a static library. It should be fairly straightfoward to build a DLL that exports routines that wrap the static library. In fact it might just be possible to write a .DEF file containing the routines to export and run the .lib and .def through the linker. It's pretty nasty though, so I'd normally go with the first route. Stability. What an interesting concept. -- Chris Maunder
