Blitting Bitmaps with the WinAPI

3 posts in this topic

Well, I guess first of all, move all the code that only needs to be done once OUT of your WM_PAINT handler like you mentioned.

Move all your clean up code to a single location as well.

Your calls to DeleteObject also need to be modified:

DeleteObject(&PicslHB) becomes DeleteObject(PicslHB)

Also, where does TilesDC come from? Does it get initialized anywhere?

Just a couple suggestions...

Ive been trying to make a level editor for a tile based game and ive run into a very large problem. The Tiles Window (actually its a modeless dialog, but thier basically the same thing) needs to be repainted when its resized etc. but after I blt the bitmap once it refuses to work again, unless re-loaded. of course this creats a slow program that has a HUGE memory leak in it. i currently useing the following code to blit to the dialog.


//hwndDlg is the HWND to the dialog

case WM_PAINT:



SelectObject(SrcDC, Pics1HB);





This code works, yet as I said above, it works very poorly. Does anyone know how to make this code better? So i only have to load the bitmap once?

Thanks for reading!

THANK YOU SO MUCH!!!!!!!!!!!!!!!!!!!!!!!

After I changed the delete object code to what you said i should it now works. I think the reason it works now is because the SelectObject() function binds SrcDC with the handle to the bitmap, and to end this binding I have to delete SrcDC. I should have had this figured out hours ago, and would have, if msdn decided they would cover a usefull topic like this, but nooo...

THANKS AGAIN!!!!!!!!!!!!!!!!!!
