VB6：如何执行.bat文件，但要等到它运行完毕后才能继续？

VB 6：如何执行.bat文件，但要等到它运行完毕后再继续？您需要在SHELLEXECUTEINFO结构中对ShellExecuteEx返回的进程句柄使用Win32 API调用和WaitForSingleObject。这是我从一个项目中提取的旧代码。这是工作100%，但我可能没有包括所有的依赖关系。您应该能够根据自己的要求进行编辑：

下面是一些简单的代码。请注意，它会发送消息（带有DoEvents），这样你的应用程序在等待时不会被冻结

Private Sub RunCommandLine(sCmdLine As String)

    Dim nProcessID      As Long
    Dim hProcess        As Long
    Dim nResult         As Long

    nProcessID = Shell(sCmdLine, vbNormalNoFocus)

    If nProcessID <> 0 Then

        hProcess = OpenProcess(SYNCHRONIZE, 0, nProcessID)

        If hProcess <> 0 Then
            Do

                DoEvents
                nResult = WaitForSingleObject(hProcess, 50)

    End If
