VB监视外部程序,用已知程序代替它

给你 个思路吧 双击Aexe时在注册表中建立一个键値0，并修改这个値=这个値+1，判断这个値<4时候立即关闭A窗口，而打开Bexe程序。等于4时候当Aexe第四次被打开时，不关闭A窗口，也不打开Bexe程序。

关键点就是保存Aexe的启动次数，可以是 *** 作注册表也可以是ini文件、txt文件，还可以追加到Aexe或者Bexe的末尾，常用于软件注册

可以使用while循环查看是否结束

Private Function MyShell(ByVal cmd As String, Optional AppStyle As VbAppWinStyle = vbNormalFocus)

Dim RetVal As Long

RetVal = Shell(cmd, AppStyle)

Do While IsRunning(RetVal)

DoEvents

Loop

'执行完毕

End Function

调用！！！

MyShell "c:\1exe", vbHide
