Following my previous post about the WScript.sleep function, here is an function to add to an exit function to a HTA.
Again, using HTA is really useful to bring life to a VBScript by adding an interface. So, converting your VBScript files to a HTA is not really complicated as VBScript is native, however some functions like the WScript.Quit are not available.
In a HTA, an easy way of exiting is to call the close method of the current Window object (self). Then, you have just to call the sbExitHTA sub to close the Window.
Also, if you want to get rid of the close button from the Windows title bar, add SysMenu="no" in the HTA:APPLICATION section.
<html>
<head>
<title>Simple HTA</title>
<HTA:APPLICATION
ID="oSimpleHTA"
APPLICATIONNAME="SimpleHTA"
>
</head>
<script Language="VBScript">
Sub Window_Onload
dataarea.innerhtml = "<p>This is a simple HTA</p>" & _
"<p>Exit button: </p>" & _
"<input type=""button"" value=""Exit"" onClick=""sbExitHTA"" />"
End Sub
Sub sbExitHTA
Self.Close()
End Sub
</script>
<body>
<h1>Simple HTA</h1>
<span id="dataarea"></span>
</body>
</html>
The WScript.Sleep function in VBScript is useful. However, when you decide to use HTA to provide an interface to your script, the sleep function become a problem as you can't use WScript functions in HTA.
For the WScript.Echo, you can use MsgBox, however, there is no equivalent for the WScript.Sleep.
You could do it using a loop, that's working but it's resource intensive. You could also create a VBScript file on the fly where you include the WScript.Sleep command and run it via the HTA but there is an easier, faster and quite efficient solution.
So, here is an option that I used several times which did the trick for me.
In the following example, the sbWait sub is run a command line to do a ping to the localhost IP address for the number of times of your choice. Because each ping request is done every second, you just have to mention using the iSeconds variable the number of time you want to do it.
Enjoy.
