Get Windows (system) variable %USERNAME%

[Aubs010]

Basically, what I want to do is get a system variable %USERNAME% into javascript...!

I started this in another forum and realised it should have been in here!


I have set up a HTA that displays training modules for users WITHIN my office.

The problem I have is finding out what modules each person has actually attempted (even viewing a second of it would suffice!).

Using login scripts, I can place shortcuts (on everyones desktop and/or start menu) to the HTA file.

The HTA file consists of 2 frames:
[tt]
+------------+------------------------+
| Module 1 | |
| Module 2 | |
| Module 3 | This is where the |
| Module 4 | module loads and |
| | is a video clip |
| | using swf |
| | |
| | |
+------------+------------------------+
[/tt]

When the user clicks on say Module 1, the swf file is loaded into the right frame.

I also want it to write to a file. It doesn't really matter how the files are saved, be it:
[tt]
| FileName | Contents |
|------------+-----------------|
| Aubs.txt | Module1 |
| | Module2 |
| Andrew.txt | Module2 |
| | Module3 |
|____________|_________________|
[/tt]

or

[tt]
| FileName | Contents |
|------------+-----------------|
| log.txt | Aubs-Module1 |
| | Andrew-Module2 |
| | Andrew-Module3 |
| | Aubs-Module2 |
|____________|_________________|
[/tt]


I have found this:

    <SCRIPT LANGUAGE='JavaScript'>
      function WriteToFile() {
        try {
          var fso, s;
          fso = new ActiveXObject("Scripting.FileSystemObject");
          s = fso.OpenTextFile("C:\\test.txt" , 8, 1, -2);
          s.writeline("This is a test");
          s.Close();
        }
        catch(err){
          var strErr = 'Error:';
          strErr += '\nNumber:' + err.number;
          strErr += '\nDescription:' + err.description;
          document.write(strErr);
        }
      }
      WriteToFile()
    </SCRIPT>

...which writes a file fine.

With batch files, this would be easy, by simply:
[tt]echo %USERNAME% - Module 1 >> \\server\folder\log.txt[/tt]
or even:
[tt]echo Completed >> "\\server\folder\%USERNAME% - Module 1.txt"[/tt]

Great news!

Basically, what I want to do is get a system variable %USERNAME% into javascript...!

Any ideas?

Thanks,

Aubs

Aubs010,

Modulo equal security issue as fso, it is this.
[tt]
var wshshell=new ActiveXObject("wscript.shell");
var username=wshshell.ExpandEnvironmentStrings("%username%");
[/tt]
