Running 2 subroutines at the same time_问答_开发者

I am trying to enhance an hta i've been working on for a while with a loding bar. I want to make the loading bar running while the other sub is being executed. I don't know how to make both subs run at the same time. Any help is appreciated.

Consider using WshShell.Exec instead of WshShell.Run.

Exec will return immediately, running the process in the back ground allowing you to complete other actions (such as updating the progress) whilst waiting for the ping to complete.

Run does not return until the process has exited and this allows you to run scripts and programs synchronously.

Given your code:

wshShell.run "cmd /c ping -n 1 -w 10 " & strComputer & ">" & TempFile,0,true  
Set results = fso.GetFile(TempFile)   
Set ts = results.OpenAsTextStream(ForReading)   
    Do While ts.AtEndOfStream <> True   
    retString = ts.ReadLine   
        If instr(retString, "Reply") > 0 Then   
            Reachable = true   
        Exit Do   
        End If   
    Loop   
ts.Close

Exec mightbe a better choice as it allows you to capture the output of the ping command while your code is still running.
