调用程序运行的问题
调用了外部的一个EXE程序进行计算,我要在程序运行的时候出现一个提示框:程序正在运行
我现在的代码是这样的
        Dim pid As Long
        pid = Shell(App.Path & "\dai.exe", vbMinimizedFocus)
        '判断计算是否完成
        hProcess = OpenProcess(PROCESS_QUERY_INFORMATION, 0, pid)
        Do
        Call GetExitCodeProcess(hProcess, ExitCode)
        DoEvents
        Loop While ExitCode = STILL_ALIVE
        Call CloseHandle(hProcess)
        MsgBox ("计算已经结束")
这段代码只是可以当程序完成的时候出现一个提示,说计算完成,但是不能显示程序运行的状态。请问在里面什么位置伽依据代码就可以了?加什么样的呢?谢谢

回复 2楼 bczgvip
就是在那里面加依据代码,然调用的程序运行的过程中给出一个提示框,说“程序正在运行”。运行结束给出提示“运行结束”。现在后边的功能实现了,前边的没有啊!
