Hi all,
I've got a script that may throw an exception and that needs to release
a resource if that happens. However, I don't want to "handle" the
exception, since I can't... I don't know what it is yet! So I try, I
catch and re-throw, and I release resources in the finally block.
However, under WSH, the finally block isn't being executed. Example:
try {
alert("try");
nonExistantCall();
}
catch(e) {
alert("catch e=[" + e + "]");
throw e; // Re-throw.
}
finally {
alert("finally");
}
alert("Complete!");
function alert(msg)
{
var objShell = WScript.CreateObject("WScript.shell");
objShell.Popup(msg);
}
If I save this as a .js file and click on it in Windows Explorer, I get
the "try", "catch" and the "WSH runtime error" (courtesy of the
re-throw). But no "finally" message!
The odd thing is, if I bung the same code into a web page (*without the
alert function*), then Internet Explorer will give me "try", "catch",
"finally" and *then* an Internet Explorer error.
So is JScript broken?
-- TIA! Peter.
