在用API作图时，如何设置与背景的混合模式，比如XOR方式。

[lightning_68]

Public Declare Function BitBlt Lib "gdi32" Alias "BitBlt" (ByVal hDestDC As Long, ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, ByVal dwRop As Long) As Long
最后一个参数是
Public Const SRCINVERT = &H660046 ' (DWORD) dest = source XOR dest

不是，我是指在画线，画圆等操作的时候。

如果用VB本身的功能就很简单，就设置窗体的DrawMode就行了，我现在需要用API作图。

大家帮帮忙呀？

没想到呀，用VB本身的DrawMode居然可以。太好了。
