Is there a way for me to check for updates? by Jacen on 05-05-2007 at 10:17 PM

I'm just wondering if theres an easy way for my script to check for updates to itself?

Sure, have your script use the Microsoft.XMLHTTP activex object to connect to the internet and download a page or file that contains update information (an XML file works nicely, but other things will work too).

Here's an example of downloading a web page with XMLHTTP:

You can also look at the source of any existing script that checks updates

So, to get the updated version I should do this

replace
Debug.Trace(xmlhttp.responseText);

with
version = xmlhttp.responseText;? I have a text file thats on my site that the only content in the file is the version number so... Would that place the version number into a varable where I can then use a IF statement to check?

Don't know what the forum rules about bumping are, but I need an answer

the rules are "dont bump or you die.(in a very serious tone.)"

and why not just try it, see if it works, whats the worsta that can happen?

Bumping is only allowed after a few days

yes that will work, but note that the variable version will be a string, not a number. So be carefull when you use comparisson operators. See the next links for more info on that:
CookieRevised's reply to Script about lock messenger
CookieRevised's reply to Nudges, Updated.

Also note that this whole routine is not instant; it runs asyncronically. Thus it can be a while (as in seconds) before anything is returned. So you also better include a time-out meganism.

Complete examples can be found in several scripts. I suggest you take a look at the bundled scripts which comes with the newest Messenger Plus! Live. For example the Now Playing script.
