Re: function in DLL

I'm still working on my DLL and is function to extract strings from the stringtable stored in the DLL.

it looks like that :
// -- mydll.cpp
extern "C" __declspec(dllexport) LPTSTR GetString(int Index)
{
TCHAR res[2048];
::LoadString(GetModuleHandle(NULL),Index, res, sizeof(res)/sizeof(TCHAR));
LPTSTR Answer(res);
return((Answer));
}
// -- mydll.h
extern "C" __declspec(dllexport) LPTSTR GetString(int Index);

however, on code --> ::LoadString(GetModuleHandle(NULL),Index, res, sizeof(res)/sizeof(TCHAR));
res is always empty... i guess that issue is with getModuleHandle.
However, after reading some post on internet, it seems correct...so where is the mistake ?


The mistake is that GetModuleHandle(NULL) will return handle to the module used to create the running process. I.e., your ..EXE file, not .DLL, which contains string table.
Youy could eliminate `GetString' function at all. Just store somewhere in main program handle to the .DLL and call CString::LoadString with this handle passed as first parameter and string index as second.
