VB 中的openprocess

[love5207070]

Private Sub Command1_Click()
Dim hwnd As Long
Dim pid As Long
Dim pro As Long
hwnd = FindWindow(vbNullString, "与 郑松 交谈中")
If hwnd = 0 Then
MsgBox ("没有找到该窗口")
Exit Sub
End If
GetWindowThreadProcessId hwnd, pid
MsgBox (pid)
pro = OpenProcess(process_all_access, False, pid)
MsgBox (pro)
End Sub

大家帮我看看,窗口打开也读到了进程,可是当我MsgBox (pro)的时候却读出来的是0?怎么会呢...

一是要提权.......试一下.

二嘛........如果你的目标是QQ,那肯定人家有保护,当然不会这么容易就让你给OPEN了......
