hi all, i am developing a small program that use a mfc dll, i am completely new in qt;
when i use this to call to a function in the dll works just fine:
QLibrary myLib("C:\\dllfolder\\MFCDLL.dll");
typedef int (*MyPrototype)(bool &con);
MyPrototype QLibrary myLib("C:\\dllfolder\\MFCDLL.dll");
typedef int (*MyPrototype)(bool &con);
MyPrototype myFunction = (MyPrototype) myLib.resolve("dllFunctionName");= (MyPrototype) myLib.resolve("dllFunctionName");
bool sw;
int nResult = myFunction(sw);
but i would like to use something like a #include directive this is possible?, i am working with visual studio 2005 i don't want to make this every time that i need a function from the dll, i have add the MFCDLL.h file to my code but still it doesn't work, any clue?
i get the follow error when i try to call the function directly from the dll icluding the MFCDLL.h file to the code and adding this line to dlltester.pro file
LIBS += C:\dllfolder\MFCDLL.dll
Error 1 error LNK2019: unresolved external symbol _dllFunctionName referenced in function "private: void __thiscall Qt_DLL_Tester::on_pushButton_2_clicked(void)" (?on_pushButton_2_clicked@Qt_DLL_Tester@@AAEXXZ) qt_dll_tester.obj
adding something: any change that i make in the .pro file doesn't look like making changes in the program.
please help.
thanks
