Hi,
as far as I know is dynamic load of MFC extension DLLs a nightmare/impossible.
The codejock DLL exposes (MFC) C++ classes, not plain stdcall C API functions. The latter are candidates for dynamic load by calling LoadLibrary/GetProcAddress.
Explore the DLL using depends e.g. As you will see, classes and methods are somehow cryptic and definition of function pointer types for C++ class functions is almost impossible - not mentioning virtual functions...

Oleg,

Yes. I did. That fixed compilation error. But when I start my app, even before creating app object, it goes into toolkit dll. Since I'm explicitly linking ,shouldn't it wait until I called LoadLibrary function. Look at call stack. Looks like it's going in DllMain() of toolkit dll.




I guess, it is still not linking explicitly. If you guys have any sample code, I would really appreciate that.

One more thing: My understanding was that lib file is not required when you link dll explicitly.

See this: http://msdn2.microsoft.com/en-us/library/ms686944.aspx

Quote Because the program uses run-time dynamic linking, it is not necessary to link the module with an import library for the DLL.

Hi,
But do you add toolkit lib file to project lib dependence?

Hi,
I'm using version 10.3.1. I was using implicit linking until now. But I want to link explicitly now onwards. I have defined "_XTPLIB_NOAUTOLINK" in preprocessor settings of project. Now I'm getting error as shown below:


-------------------------------
Error    23    error LNK2019: unresolved external symbol "__declspec(dllimport) public: enum XTPPopupState __thiscall CXTPPopupControl::GetPopupState(void)const " (__imp_?GetPopupState@CXTPPopupControl@@QBE?AW4XTPPopupState@@XZ) referenced in function "long __cdecl PopUpNotify(unsigned int,long)" (?PopUpNotify@@YAJIJ@Z)
--------------------------------


I looked at all exported symbols/functions/classes using dumpbin utility provided with Visual Studio. It shows this function is exported as:


-----------------------------------
6420 1913 003347DB ?GetPopupState@CXTPPopupControl@@QBE?AW4XTPPopupState@@XZ = @ILT+18390(?GetPopupState@CXTPPopupControl@@QBE?AW4XTPPopupState@@XZ)
-----------------------------------


Only difference is __imp_ prepended in first:

__imp_?GetPopupState@CXTPPopupControl@@QBE?AW4XTPPopupState@@XZ

as comapared to exported one:

?GetPopupState@CXTPPopupControl@@QBE?AW4XTPPopupState@@XZ

Looks like compiler is still looking for import library. How can I fix this problem?
