Thread: Bitmap Display Probelm

made many changes. got it working. you need to look up wm_paint.

i moved bitmap to see if it display. put back where you want.

let see if .zip attaches.

edit will not allow zip "invalid file type"

Code:

under case wm-creat at end


   // Load the bitmap from the resource
			        bmpExercising = LoadBitmap(GetModuleHandle(NULL), MAKEINTRESOURCE(IDB_EXERCISING));


under wm-paint


                               BITMAP bm;                               

                               PAINTSTRUCT ps;



				HDC hdc = BeginPaint(hwnd, &ps);

				// Load the bitmap from the resource
			      //  bmpExercising = LoadBitmap(hInstance, MAKEINTRESOURCE(IDB_EXERCISING));
				// Create a memory device compatible with the above DC variable
				HDC MemDCExercising = CreateCompatibleDC(hdc);
					 // Select the new bitmap
				HBITMAP hbmOld = SelectObject(MemDCExercising, bmpExercising);

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

				// Copy the bits from the memory DC into the current dc
				BitBlt(hdc, 20, 20, bm.bmWidth, bm.bmHeight, MemDCExercising, 0, 0, SRCCOPY);

				// Restore the old bitmap
                                SelectObject(MemDCExercising, hbmOld);

				DeleteDC(MemDCExercising);
				// DeleteObject(bmpExercising);
				EndPaint(hwnd, &ps);
		}
		break;

also added hbitmap

Code:

const char g_szClassName[] = "myWindowClass";
HINSTANCE hInstance;

HBITMAP bmpExercising = NULL;

LRESULT CALLBACK WndProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
//	HDC hDC, MemDCExercising;
 //   PAINTSTRUCT Ps;
  //  HBITMAP bmpExercising;
