Code:

#include <windows.h>
#include "Resource.h"

int WINAPI WinMain (HINSTANCE hInstance,
                    HINSTANCE hPrevInstance,
                    LPSTR lpCmdLine,
                    int iCmdShow)

    DWORD err = 0;

    HRSRC hrsrc = ::FindResource( hModule, MAKEINTRESOURCE(MYTXTFILE), TEXT("BIN"));
    ::GetLastError(); if(err) { TCHAR bug[256]; wsprintf(bug, TEXT("%d"), err); ::MessageBox(0, bug, bug, 0); }
    HGLOBAL rsc = ::LoadResource( NULL, hrsrc );
    err = ::GetLastError(); if(err) { TCHAR bug[256]; wsprintf(bug, TEXT("%d"), err); ::MessageBox(0, bug, bug, 0); }
    LPVOID lock = ::LockResource( rsc );
    err = ::GetLastError(); if(err) { TCHAR bug[256]; wsprintf(bug, TEXT("%d"), err); ::MessageBox(0, bug, bug, 0); }
    DWORD size  = ::SizeofResource( NULL, hrsrc );
    err = ::GetLastError(); if(err) { TCHAR bug[256]; wsprintf(bug, TEXT("%d"), err); ::MessageBox(0, bug, bug, 0); }
    
    MessageBox( HWND_DESKTOP, (const char*) lock, "", MB_OK );
    
    return 0;
}

Not a graceful error handling system, but it'll tell you what happened.

I'm still having problems with loading resources, here is the most up to date code:

main.cpp:

Code:

#include <windows.h>
#include "Resource.h"

int WINAPI WinMain (HINSTANCE hInstance,
                    HINSTANCE hPrevInstance,
                    LPSTR lpCmdLine,
                    int iCmdShow)
{
    HMODULE hModule = GetModuleHandle(NULL);
    DWORD err = 0;

    HRSRC hrsrc = ::FindResource( NULL, MAKEINTRESOURCE(MYTXTFILE), TEXT("TEXT"));
    err = ::GetLastError(); if(err) { TCHAR bug[256]; wsprintf(bug, TEXT("%d"), err); ::MessageBox(0, bug, "1", 0); }
    HGLOBAL rsc = ::LoadResource( NULL, hrsrc );
    err = ::GetLastError(); if(err) { TCHAR bug[256]; wsprintf(bug, TEXT("%d"), err); ::MessageBox(0, bug, "2", 0); }
    LPVOID lock = ::LockResource( rsc );
    err = ::GetLastError(); if(err) { TCHAR bug[256]; wsprintf(bug, TEXT("%d"), err); ::MessageBox(0, bug, "3", 0); }
    DWORD size  = ::SizeofResource( NULL, hrsrc );
    err = ::GetLastError(); if(err) { TCHAR bug[256]; wsprintf(bug, TEXT("%d"), err); ::MessageBox(0, bug, "4", 0); }
    
    MessageBox( HWND_DESKTOP, (const char*) &lock, "", MB_OK );
    
    return 0;
}

resources.rc:

Code:

#include "Resource.h"

MYTXTFILE TEXT "mytextfile.txt"

Resource.h:

Code:

#ifndef RLOADER_RESOURCE_H
#define RLOADER_RESOURCE_H

#define MYTXTFILE                  10001

#endif

And mytextfile.txt simply contains "ABC". The first GetLastError function used returns two, which according to msdn means "The system cannot find the file specified." I can't work out how to fix this though, maybe it's a problem with devcpp but I'm out of ideas. Do you (or anyone really) know how to get this program to work? Thanks.
