Hello guys, anyone could help me, here in my codes..
My problem is that, when i Blit my surface in my backbuffer, then blit my backbuffer onto the primary.. nothing is shown.. only plain black..
Here is my code:
Code:
Public Sub InitWindow(WindowHWND As Long, Optional WindowHWND2 As Long)
Dim caps As DDSCAPS2
caps.lCaps = DDSCAPS_BACKBUFFER
MainWindowHWND = WindowHWND
MainWindowHWND2 = WindowHWND2
Set DD = DX.DirectDrawCreate("")
DD.SetCooperativeLevel WindowHWND, DDSCL_NORMAL
ddsd1.lFlags = DDSD_CAPS
ddsd1.ddsCaps.lCaps = DDSCAPS_PRIMARYSURFACE
Set Primary = DD.CreateSurface(ddsd1)
ddsd2.lFlags = DDSD_CAPS Or DDSD_WIDTH Or DDSD_HEIGHT
ddsd2.ddsCaps.lCaps = DDSCAPS_OFFSCREENPLAIN Or DDSCAPS_3DDEVICE
ddsd2.lWidth = 320
ddsd2.lHeight = 240
Set picBuffer = DD.CreateSurface(ddsd2)
End Sub
Public Sub AttachSurface(Surface As DirectDrawSurface7, onWindowX As Long, onWindowY As Long, cropX1 As Long, cropY1 As Long, cropX2 As Long, cropY2 As Long)
Dim MainWindowRect As RECT
Dim cropRect As RECT
Dim cropRect2 As RECT
...
picBuffer.Blt MainWindowRect, Surface, cropRect, DDBLT_WAIT
Primary.Blt MainWindowRect, picBuffer, cropRect2, DDBLT_WAIT
...
End Sub
