For loop help

[Brady]

I'm creating a script to run install programs in silent mode, the idea being that someone will run the program and it will install a group of programs all at once. It will also display a progress bar so that the user knows that something is happening and when it is done.

Problem is that I'm getting an error saying: "Variable must be of type "Object" after it gets done with all of the files and so it never leaves the loop to display the completed progress bar and exit.

The line is occuring on line 53, which is the line just following

You need to do some reading about For/Next-loops. Test this :

For $i = 1 To $file_array[0]
    ;RunWait(@ScriptDir & "\" & $dir & "\" & $file & " " & $switch,@ScriptDir & "\" & $dir)
    MsgBox(1, 'test', @ScriptDir & "\" & $dir & "\" & $file_array[$i] & " " & $switch)
    $progress = $progress + 1
    ProgressSet($progress / $num_files * 100)
Next

Can you reccomend somewhere to do this reading? I've read what is in the help file, and I'm still unsure why my code doesn't work. Most confusing is that the code having problems is exactly like a loop earlier in the code that works just fine.

Test this :

For $i = 1 To $file_array[0]
    ;RunWait(@ScriptDir & "\" & $dir & "\" & $file & " " & $switch,@ScriptDir & "\" & $dir)
    MsgBox(1, 'test', @ScriptDir & "\" & $dir & "\" & $file_array[$i] & " " & $switch)
    $progress = $progress + 1
    ProgressSet($progress / $num_files * 100)
Next

When I try that code I get the following error message:

Subscript used with non-Array variable.

Thanks,

I was able to get it working by using:

For $i = 1 To UBound($file_array) - 1

I'm still not sure why neither the original or the solution posted by Helge worked properly. If anyone has any ideas I would love to hear them. I'm pretty new to AutoIt so I know I've got lots to learn still.

Thanks for your help Helge.

Yes, I was thinking about the helpfile. Just read the docs and study the example.

That error-message means that _FileListToArray has failed, so you should add a

error-check after using that function. If @error doesn't equal 0 then you've either

done something wrong or there aren't any files in the directory.

You nailed it on the head. One of the directories that it is parsing doesn't have any files in it yet, so that's what was causing the error.

I've added the error check and it's working exactly as it should.

Thanks again for your help Helge!
