Thread: How do I use Resources from a Resource-Only DLL?

Okay, I created a resource-only DLL and I am trying to make an application that can load an image from it, such as a bitmap or icon.

Here is my DLL code:

Code:

#include "stdafx.h"

#ifdef _MANAGED
#pragma managed(push, off)
#endif

BOOL APIENTRY DllMain(HMODULE hModule,
    DWORD ul_reason_for_call, LPVOID lpReserved)
    {
    return TRUE;
    }

#ifdef _MANAGED
#pragma managed(pop)
#endif

Then Here is the Resource file include with it:

Code:

ICON_MAIN ICON "icon.ico"

This all compiles perfectly to a DLL. Then I can't seem to figure out how to load it into my project correctly.
Here is the code I use to load the icon image:

Code:

const char* pFileName="resdll.dll";
HMODULE hinstdll = LoadLibrary(pFileName);
HICON myicon = LoadIcon(hinstdll,ICON_MAIN);
FreeLibrary(hinstdll);

The program compiles without error if I remove the LoadIcon line, so that is my problem I suppose. When I try to compile I get the error:
"error C2065: 'ICON_MAIN' : undeclared identifier"
How can I fix this?

Please explain to me where to inlcude cuz I have no idea where.
It is in the project so it is being compiled and what not...

Ok well now I get it to compile but the program doesn't successfully load the icon... why is this? i don't get any errors but I tried using it as the window's small icon and it doesn't display my icon, just some other default.

Raven Arkadon is correct for C/C++ files, but resource includes need to be set up slightly differently.

In a file called, "resource.h" have the following:

Code:

#define ICON_MAIN 101

The number 101 is arbitary. Each resource you add needs a define and a unique number.

Now include this file at the top of both your .rc file and your .cpp files:

Code:

#include "resource.h"
