End Sub
Private Sub Form_MouseDown(Button As Integer,Shift As Integer,X AS Single,Y AS Single)
PaintStart=True
End Sub
Private Sub Form_MouseMove(Button As Integer,Shift As Integer,X As Single,Y As Single)
If PaintStart Then
PSet(X,Y)
End If
End Sub
Private Sub Form_MouseUp(Button As Integer,Shift As Integer,X As Single,Y As Single)
End Sub
Private Sub Form_DblClick()
Cls
End Sub
