我有一个通常需要运行的应用程序,而无需积极监控,但是,如果遇到错误,它将弹出消息窗口并暂停,直到用户按下关闭。目前,由于我们正在压力测试,并且无法禁用这些消息,因此它正在引起很多问题,因此有人必须不断地关注该过程。我一直在尝试提出一些VBScript,这些VBScript将继续检查弹出消息并使用AppActivate
和SendKeys
函数自动关闭它。
问题是我需要在GUI中工作,以便用户可以在单击按钮时轻松启动/停止代码运行。因此,我目前将我的vbscript包裹在一个带有一个按钮的HTA应用程序中,但是由于某种原因,它只会关闭消息的第一个实例(多个可以同时加载多个),然后停止。
。Sub Testing
Set objShell = CreateObject("WScript.Shell")
counter = 1
Do While counter < 50
ret = objShell.AppActivate("Test Failure")
counter = counter + 1
If ret = True Then
objShell.SendKeys "~"
End If
Loop
End Sub
使用按钮如下:
<input type="button" value="Run Script" name="run_button" onClick="Testing"><p>
我需要它只是在后台不断运行,仅在选择"测试失败"窗口/存在时才执行SendKeys
,并且在按下第二个按钮时能够停止循环。
我显然遇到了一些问题(VBScript确实执行了上下,不是吗?
我已经标记了@ansgar Wiechers的回答,就像解决了我的问题的根本原因一样正确。我最终提出的最终代码分为两个部分。应用程序:

Set sh = CreateObject("WScript.Shell")

If cmdTest Is Nothing Then
Set cmdTest = sh.Exec("wscript.exe """ & script & """")
strVar = "testing"

和支持的VBScript文件:
Set sh = CreateObject("WScript.Shell")
While True
active = sh.AppActivate("#WINDOW TITLE#")
If active Then
sh.SendKeys "~"
End If
WScript.Sleep 100
Wend
您的过程正在毫不拖延地进行50次迭代,因此它甚至可能已经完成了第二个实例。您通常要做的就是在无限延迟的无限环中运行AppActivate
和SendKeys
:
Set sh = CreateObject("WScript.Shell")
While True
active = sh.AppActivate("Test Failure")
If active Then
sh.SendKeys "~"
End If
WScript.Sleep 100
Wend
将其放在您从HTA上异步运行的脚本:
<html>
<head>
<title>sample</title>
<HTA:APPLICATION
ID="sample"
APPLICATIONNAME="oHTA"
SINGLEINSTANCE="yes">
<script language="VBScript">
script = "C:pathtoscript.vbs"
Set sh = CreateObject("WScript.Shell")
Set cmd = Nothing
Sub StartLoop
If cmd Is Nothing Then
Set cmd = sh.Exec("wscript.exe """ & script & """")
End If
End Sub
Sub StopLoop
If Not cmd Is Nothing Then
cmd.Terminate
Set cmd = Nothing
End If
End Sub
</script>
</head>
<body>
<p>
<button id="start" onclick="StartLoop">Start</button>
<button id="stop" onclick="StopLoop">Stop</button>
</p>
</body>
</html>
如果需要,您可以即时从HTA创建外部脚本:
Set fso = CreateObject("Scripting.FileSystemObject")
...
Set f = fso.OpenTextFile(script, 2, True)
f.WriteLine "Set sh = CreateObject(""WScript.Shell"")"
f.WriteLine "While True"
f.WriteLine "active = sh.AppActivate(""Test Failure"")"
...
f.Close
并在终止后删除它:
If Not cmd Is Nothing Then
cmd.Terminate
Set cmd = Nothing
fso.DeleteFile script, True
End If
