OK...question 1 - what are you talking about??

Do you mean importing a bitmap as a resource?

i dont know! im asking you guys, lol, cus, when i try to compile, instead of being able to click on "execute" it says "show compiler results", and i click on that, and the title of the window is "Linker Output" and it has a bunch of **** like "C:\\dev C++\\blah blah" Object4@something" something...

post your code

Bmp_one.c

Code:

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

const char g_szClassName[] = "myWindowClass";

HBITMAP g_hbmBall = NULL;

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
	switch(msg)
	{
		case WM_CREATE:
			g_hbmBall = LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE(IDB_BALL));
			if(g_hbmBall == NULL)
				MessageBox(hwnd, "Could not load IDB_BALL!", "Error", MB_OK | MB_ICONEXCLAMATION);
		break;
		case WM_CLOSE:
			DestroyWindow(hwnd);
		break;
		case WM_PAINT:
		{
			// Just a note, never use a MessageBox from inside WM_PAINT
			// The box will cause more WM_PAINT messages and you'll probably end up
			// stuck in a loop

			BITMAP bm;
			PAINTSTRUCT ps;

			HDC hdc = BeginPaint(hwnd, &ps);

			HDC hdcMem = CreateCompatibleDC(hdc);
			HBITMAP hbmOld = SelectObject(hdcMem, g_hbmBall);

			GetObject(g_hbmBall, sizeof(bm), &bm);

			BitBlt(hdc, 0, 0, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY);

			SelectObject(hdcMem, hbmOld);
			DeleteDC(hdcMem);

			EndPaint(hwnd, &ps);
		}
		break;
		case WM_DESTROY:
			DeleteObject(g_hbmBall);
			PostQuitMessage(0);
		break;
		default:
			return DefWindowProc(hwnd, msg, wParam, lParam);
	}
	return 0;
}

bmp_one.rc

Code:

IDB_BALL                BITMAP  DISCARDABLE     "ball.bmp"
