Re: DLL function loading issue

Sorry but it did not change anything.
it seems that issue is with static keyword... i do not understand why, but it is not with __stdcall.

Here is an updated version of my code with typedef and the relative errors
:
// --- myclass.h
typedef LPTSTR (__stdcall *FUNCT_LocGetString)(long);
From MSDN:
"/Gd, the default setting, specifies the C calling convention for all
functions except C++ member functions and functions marked __stdcall or
__fastcall."
So unless you changed the compiler options or specified __stdcall in the
declaration of your function you're most likely to get a runtime error

<code sniped>

VC raises following errors :
CARDLLWrapper.obj : error LNK2001: unresolved external symbol "private:
static char * (__stdcall* CARDLLWrapper::LocGetString)(long)"
(?LocGetString@CARDLLWrapper@@0P6GPADJ@ZA)

CARDLLWrapper.obj : error LNK2001: unresolved external symbol "private:
static struct HINSTANCE__ * CARDLLWrapper::m_hlibLoc"
(?m_hlibLoc@CARDLLWrapper@@0PAUHINSTANCE__@@A)
This has nothing to do with the function pointer nor the function itself,
but rather with the declaration of the static variable inside the class.
From what I can see this varaible isn't "defined" anywhere. So what you need
to do is to define it somewhere (in one of your source files) exacly once
(Much like a function: It has a declaration and a definition). Your
definition should look something like this:
FUNCT_LocGetString CARDLLWrapper::LocGetString; // Possibly with
initialization
