如何建立直接链接以执行.hta文件？

Question

I have an .hta file on a mapped drive that I can manually navigate to, double-click on the .hta file and it executes fine. However, I added a link to the full path on the share (from an IE 8 page) and when I try to run it from the link, as in:

Q:\\path...\\.hta

Then I get a javascript error an error occurred in running the script "length is null or not an object". The javascript code is coming from the .hta file itself on this line:

...
for (var i = 0; i < matches.length; i++) { 
...

I'm guessing that for some reason "i" isn't initialized when the .hta is run off the link, rather than manually.

In any event, when I try to directly go to the file from the link, I do get a dialog asking if I want to run, save, or cancel the .hta file. When I try to run it, I get the javascript error.

So my questions are:

1. how do I run this .hta file from a browser link?
2. why do I get the javascript error when run from a link and not when it's run manually?

Answer 1

HTA does not recognize mapped drives.

I assume you have your application saved at server, and then you run it at workstation, where you have this mapped driver Q as a shortcut to the server.

The correct path to server is something like this:

//Your_Server_Name/path_in_server/file.hta

An actual IP can also be used instead of the Your_Server_Name .

To run the HTA in browser (IE only) without prompts, you'll need to change many settings in Intranet zone security- and Advanced-tab to very insecure mode.

About the error message:

It seems, that matches has not a property named length . If matches is defined, it's probably a number or a boolean, or some other type of object which has not the length property.

If the message is something like this: Can't get the property length: object is null or not defined . This means, that matches is undefined.

Notice, that HTA is an independent application with it's own top.window , and it can't interact with the browser window. (There is no way to refer the opener in HTA, if the opener is a browser window.)
