Sounds like your surfaces are getting lost.
Your app needs to detect when its losing/gaining focus (check out windows messages in MSDN) and reload bitmaps and restore surfaces.
You''ll get info on this on the microsoft directX site.

OK, How I can detect if my program lost the focus, with Form_Deactivate() event ?, and I need reload all surfaces including primary and secundary surfaces, or offscreen surfaces only ?
Thanks !!

When ur program is activated or desactivated u receive a WM_ACTIVATE or WM_ACTIVEAPP message(check mdsn for that).
Then to check if ur surface has gone u use UrSurface.IsLost() function. And to restore it u use UrSurface.Restore().
But i heard like u can call a RestoreAllSurface() from ur primary surface for restoring all the surfaces without calling Restore from all ur onscreen and offscreen surfaces.
Hope this help

Thanks for your help, but I doing this and the program return the DDERR_WRONGMODE error, check this please:
----------------------------------------------
This code detect if the program lost the focus
into the main loop
----------------------------------------------
Sorry for not tell you, I'm using VisualBasic. HWND_ACTIVO = GetActiveWindow If HWND_ACTIVO <> DX_CAT.hWnd Then Do HWND_ACTIVO = GetActiveWindow DoEvents Loop While HWND_ACTIVO <> DX_CAT.hWnd CHECAR_SUPERFICIES_PERDIDAS End If ------------------------------------------
This code restore all surfaces if is lost
------------------------------------------
Sub CHECAR_SUPERFICIES_PERDIDAS ()'Primary surfaceIf PRIMARIO.SUPER.isLost = DDERR_SURFACELOST Then PRIMARIO.SUPER.restore'Secundary surfaceIf SECUNDARIO.SUPER.isLost = DDERR_SURFACELOST Then SECUNDARIO.SUPER.restore'All surfacesFor I = 1 To UBound(IMAGENES) If IMAGENES(I).SUPER.isLost = DDERR_SURFACELOST Then IMAGENES(I).SUPER.restoreNext IFor I = 1 To UBound(IMG_CAT) If IMG_CAT(I).SUPER.isLost = DDERR_SURFACELOST Then IMG_CAT(I).SUPER.restoreNext IFor I = 1 To UBound(BOTON) If BOTON(I).BOT_SUPER.isLost = DDERR_SURFACELOST Then BOTON(I).BOT_SUPER.restoreNext IEnd Sub Ing.
