[gdi] Erasing Window

[zorro59]

Hello everyone!
My problem is this:

case WM_PAINT:
		{
			PAINTSTRUCT ps;
			HDC hdc = BeginPaint(imagine_aux, &ps);

			
				
			        RestoreDC(hdc,-1);//reinitializez fereastra, cum era inainte de desenat
				
				HDC hdcMem = CreateCompatibleDC(hdc);
				SelectObject(hdcMem, imagine_bmp);

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

				BitBlt(hdc, image_x, image_y, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY);//redesenez imaginea

				//SelectObject(hdcMem, hbmOld);
				DeleteDC(hdcMem);
		
			EndPaint(hwnd, &ps);
			break;
		}

I am sending InvalidateRect from another function. What i want to do is this:
Erase the current window (imagine_aux), then send RestoreDc to get the initial image.
So after a HBITMAP was loaded, i save the dc, when it was moved, i simply want to delete everything and redraw the bitmap in the new position.
The bitmap loads, the image is moved, but the window isnt't reinitialised , so i get the trail.
