I found that in Line 53, the line ends with a character & and the remaining of the line starts at line 55, which is not allowed. In case you have multiple lines, you need to
add an underscore character "_" (without quotes) afterwards like this:

I got it to work.  I rearranged it a lot.  It didnt seem to like the <center> tag where it was.  I also had it write everything to a string first, then when its done, it displays the string in the innerhtml part (may take some time depending on how long your list of computers is).  I dont have too much experience with hta's (my html skill is weak), but from what I know, its better to make a string then do the string in one shot.

TakedaT i hope you dont mind me asking 1 final question about this.
What you have done is excellent.
Is there a way to slightly modify your code so that:

1) Instead of hardcoding the text file

strComputersFile = "servers.txt"  (line 46)

2) You can create a browse button, and point to a text file of your choice?

So, instead of hardcoding

strComputersFile = "servers.txt"

You would have something like:

Please select a file to process ___________  <Browse>

Then the script would process that chosen file instead?

You are fantastic guys.

Here you go.  Now, this will ONLY work in windows XP.  You will get errors on other operating systems if you try to run it.  Even on this pc im on now wont run it (vista).

Hi TakedaT, youre a genius.

Those new lines you added.....if you wanted to create a new button to click so that this new button would prompt you for a text file, could you do that?
So, you would have:


<Click to point to a filename>
<Click to Get Service Pack>
