Loading a DLL using Qt

[srohit24]

Hi

I have created a DLL named firstdll.dll and its written in C. It has only 1 function, named Display(), which i am exporting. When i call that function, it returns a string.

Now my question is how can I load that dll into my c++ application, so that i can get the string and display it?

I am trying using LoadLibrary() and other such functions to load the dll but i am not able to make it work. (In C# and VB its not that tough, but since i want to use c++ and Qt, i am finding it very hard to load the dll.)

I am using this code

HMODULE hDll = LoadLibrary("firstdll.dll");
FARPROC fpDisplay = GetProcAddress(hDll, "Display");
typedef char* (__stdcall *fpDisplayT)();
fpDisplayT Display = (fpDisplayT)fpDisplay;

but i get the following error

Error 1 error C2664: 'LoadLibraryW' : cannot convert parameter 1 from 'const char [12]' to 'LPCWSTR'

How can i solve this error?

It would be very helpful if you can give me the complete code to load the dll and then how to retrieve a string that dll returns when called.

thanks in advance.
