I am loading 2 images (sprite and mask) into DC that I have created using the CreateCompatibleDC api, and then I blit them into the screen. My question is: How do I create another dc so I can blit the new transparent image (result of mask + sprite) into it, and not into the form.

The code I am using is the following, but it doesn't work, even though I don't get any errors. But is works OK when I blit them into the screen.

VB Code:
  1. Private Sub Form_Activate()

  2.  
  3. 'Create DC

  4. MaskDC = CreateCompatibleDC(Me.hdc)

  5. SpriteDC = CreateCompatibleDC(Me.hdc)

  6. FinalImageDC = CreateCompatibleDC(Me.hdc)

  7.  
  8. 'Load images

  9. MaskIM = LoadImage(0, "C:\WINDOWS\Desktop\Henrique\Shooter\Images\target_hit_mask.bmp", 0, 0, 0, &H10)

  10. SpriteIM = LoadImage(0, "C:\WINDOWS\Desktop\Henrique\Shooter\Images\target_hit_sprite.bmp", 0, 0, 0, &H10)

  11.  
  12. 'Link DC with image

  13. SelectObject MaskDC, MaskIM

  14. SelectObject SpriteDC, SpriteIM

  15.  
  16. 'Go through each separate part of the images

  17.     Do

  18.         

  19.         DoEvents

  20.         Me.Cls

  21.         

  22.         'This is what does not work, the FinalImageDC

  23.         BitBlt FinalImageDC, 10, 10, 30, 74, MaskDC, x, 0, vbSrcAnd

  24.         BitBlt FinalImageDC, 10, 10, 30, 74, SpriteDC, x, 0, vbSrcPaint

  25.         

  26.         x = x + 31

  27.         

  28.         If x >= 740 Then

  29.             x = 0

  30.         End If

  31.                

  32.     Loop Until GameOver = True

  33. End Sub

Is this the right way of doing this, or is there another API call for this?

Thanks
