GUI / HTA

10 posts in this topic

OK, a little background...

I've messed with AutoIT in the past, over a year ago, and never really had the time to get really involved with it.

This week I was finally able to put AutoIT to work. I had to duplicate an EXE to track who was using a particular application (along with the machine they ran it from and what time). This worked out perfectly for me.

Current:

Our company is switching everyones' regular workstations to 'Ultra-thin-clients'. We have decided on the route of the SUN Ultra-Thin DTU's (Desk-Top Unit) - http://www.sun.com/sunray/sunray2/index.xml.

One problem that we have come across is with local printers. To enable the local printer on these DTU's you have to add the printer information into the script that runs on the Sun server. The big problem with that is that it sets the 'local' printer up on every DTU connection and sets it as the default printer; no matter if they have a 'local' printer or not.

I've created an HTA to handle this problem, but I was thinking about using AutoIT (specifically the function to wrap into an EXE) but I wasn't sure if I can just wrap the HTA up with AutoIT, or if I need to recreate it solely in AutoIT.

This HTA is placed in the StartUp, so the first time someone logs into their session this HTA will launch.

It displays the current 'default' printer, which is currently the 'local' printer, and gives them the option to set a new 'default' printer.

If they decide to change the default printer:

There is a textbox for them to enter that printer. The HTA will then check to see if the printer is currently installed.

If the printer is not installed:

Attempt to install that printer (if the printer does not exist, or they typed it wrong, they are displayed a message box and asked to retype the printer name)

If the printer is installed:

Sets that printer as the default

If they decide to leave the current printer as the default:

Nothing needs to be done

Once all of that takes place a text file is created in their profile with the printer they have set as their default.

Now, whenever they log in, the HTA will locate that file and set that printer as their default.

I know this is a little clunky to take care of this, but until we can find a 'better' solution on the Sun side, this is what we are going with.

The HTA works fine, but if I was able to wrap this up as an EXE (or 'gasp' try to re-create this with AutoIT), we don't have to worry about anyone going in and messing up any of the code in the HTA (since this resides on their machine).

I'm currently searching through the forum, but appreciate anyones feedback as for the best way to go with this.

I don't know anything about the Sun stuff, but i can say you have a couple of options. It seems your concern is to protect the hta script from users .

1.Rewrite the code in AutoIt.....assuming you know vbscript, autoit is a rather simple transition. There is an example script somewhere on the forum for converting vbscript to autoit.

2. Use Autoit to create/run and delete the hta at runtime as required.

3. Use Autoit to Run the hta....ShellExecute is one method.

4. Google "script2exe" or "vbscript2exe" is free

Cheers

By HTA I presume you mean a MS Internet Explorer HyperText Application file?

It's not a bad way to go as an HTA gives access to local resources and bypasses many of the browser security restrictions.

AutoIt on the other hand never has to worry about those types of security restrictions. I would expect that writing such an application in AutoIt would be much more straight forward than doing it in hta/html/javascript. You can either use the AutoIt GUI or you can even use COM to work with a browser interface (using IE.au3 UDF perhaps).

Thank you both for the info; I kind of assumed it would come down to recreating the HTA (MS Internet Explorer HyperText Application) with AutoIT.

I just wasn't sure, since I haven't spent a whole lot of time working with AutoIT, if there was some sort of 'include' so that I could wrap my current HTA up into an EXE using AutoIT.

I'll definitely take a look into the "script2exe" & "vbscript2exe"; I believe I've come across those before, but for some reason didn't go that route... (they just ring a bell for some reason)

Anyways, I appreciate the info you provided.

Hopefully it won't take too much to convert this HTA; and I won't have to post too many questions out here on it.

Thanks,

You explained what you are doing now, but you didn't really make it clear what your current solution doesn't do for you and what you are really trying to create. With that info you might get more suggestions.

I have a functional HTA that does exactly what I want it to do.

This HTA is placed in the Startup on all of the Virtual Workstations so that it runs as soon as the individual logs in.

If it finds a file called "PrintDefault.txt" inside the users profile: C:\Docum~1\<username> then it reads the file and sets the default printer to what is in the PrintDefault.txt.

If there is no file found, then the HTA will pop-up and have the individual fill out what printer they want to set as their default. Once they 'submit' their information the HTA looks to see if that printer is currently installed (installs if need be) then sets as default. It will then create the "PrintDefault.txt" so that it will be used the next time the user logs in.

Problem: Nothing is stopping the user from editing the HTA and messing up the code.

My main reason for posting my question was to see if I could use my existing HTA and just wrap it up with AutoIT so that it is now an EXE instead of HTA.

If this IS possible, than that would be great.

Only other option would be to create an EXE to launch the HTA from a different location. This way the individual does not know where the HTA resides, and is unable to mess with the code.

Let me know if you need anything else.

Ah, OK.

First questions is couldn't you store the .hta on a network share that allows only read access?

Regarding "wraping" the hta code... one simple thing to do would be to use a compiled AutoIt script to create the .hta file on the fly, execute it and have the hta file delete itself when it completes.

Problem with storing on a Network Share:

HTA's are designed to run locally; you may come across an "ADO Security Warning" whenever the HTA is launched from the network. Will have to test that portion out since the only HTA's (that I've created) connect to some sort of Database. Connection to the registry may not cause that.

So I could try looking at that route.

AutoIT script to create HTA on the fly:

I haven't figured out how to fit all of the HTA into a working AutoIT script. Consider me a NOOB right now, but plan on working with this so that I can push out AutoIT scripts as well as my VBScripts.

The current HTA is right at 191 lines; 32 lines are HTML.

So, for the time being, I'm going to look at the "network share" route, to see if I can create a reg query that the "basic" user can run.

I really want to go the AutoIT route, but I may need to get a little more familiar with the syntax and layout of AutoIT.

Any pointers to assist in my journey will be appreciated.

I've attached the HTA that I've been talking about. We currently have two print servers, so those are the ones referenced in this HTA. (Layout of my script with these code tags isn't as pretty as in my TextEditor)

Good read, at least it gives me an idea on creating through AutoIT.

The reg query is able to run without any issues from a network share, at least with the individuals I was able to test this out on.

So, I was able to place my HTA out on a network share and create a very nice little EXE to launch it.

RunWait("mshta.exe \\<server>\<share>\DefaultPrinter.hta")

Was able to use a printer icon for the EXE itself (used Easy Icon Maker to extract the printer icon from Shell32.dll) so it looks pretty professional.

I still plan on writing, not sure if you would actually call it an HTA or EXE now, through AutoIT.

I'm supposed to create another HTA (basically the same as the first), but this will give the individual a chance to 'change' their default printer after they have already used the first HTA to set it up.

Reason: if their default printer is down, they move to a new location and need to use a different printer, they just get tired of using that printer.

Since I have this nice EXE ready to deploy I can spend a little more time on this next one.

I guess it's time to really dig into the AutoIT Help file to start familiarizing myself more.

Thanks for all your help; those links and ideas got me going again when I reached a stalemate ( :D ) on my scripting.

:)

Forgot to mention; best part of it residing on the network is that it will be extremely easy to update if need be. (Hate to try to update this once it's pushed out to over 2000 Virtual Workstations)
