Question

VB后台点击,执行窗口指定位置点击.就是相对坐标.问题

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Type POINTAPI
X As Long
Y As Long
End Type

Dim game As Long

Private Sub Command1_Click()
Dim a As Long, b As Long
Dim point As POINTAPI
a = 400
b = 300
X = point.X
Y = point.Y

game = FindWindow(vbNullString, "xxx执行窗口")
ClientToScreen game, point.X, point.Y

mouse_event MOUSEEVENTF_LEFTDOWN Or MOUSEEVENTF_LEFTUP, 0, 0, 0, 0 '模拟鼠标的左键单击!
End Sub

哪里错了。谢谢高手解答。或者给一个好的代码。完整一点。
我是用api的 ClientToScreen函数。如果其他可以的话。请告诉我一下。谢谢
