Can Somebody HELP me there?!!

I'm confusing with the error that pop out while i compile the entire program. The question is the error message "OverFlow!" is only apprear i other PC, but never occur on my own PC. As the complier tell me the error is occur on the line of coding, as follow:

SUCCESS = BitBlt(Solo_Game.hDC, MeCurrentPostX, MeCurrentPostY, Graphic.PicSR71b.ScaleWidth, Graphic.PicSR71b.ScaleHeight, Graphic.PicSR71b.hDC, 0, 0, vbSrcAnd)

SUCCESS = BitBlt(Solo_Game.hDC, MeCurrentPostX, MeCurrentPostY, Graphic.PicSR71a.ScaleWidth, Graphic.PicSR71a.ScaleHeight, Graphic.PicSR71a.hDC, 0, 0, vbSrcPaint)

Is there any error on these line of codes?
