chkdsk gui in WinPE array error

[hackersarchangel]

I have a project I'm working on, as part of a maintenance disk. I want to make a GUI for automating chkdsk startup, as in I run the GUI, then I select what drives I'm wanting to chkdsk. I want to run this from a PE based enviroment, I believe the disk I've chosen is a BartPE based disk, if that matters.

Here's where my issue comes into play. When I start the program I have it set to specify a log save location with a Save As box. That part works great, so I have it make the GUI. Here's the issue: When I'm making the GUI, I want it to grab the drive letters and use that as part of either Checkboxes OR multiple dropdown menus. That part I'm flexible on, I just want it to work, and the dropdown menus was just another way of thinking about it.

So I figured out how to grab drive letters into an array and do an If-Then for less than 4 drives (test machine has 3 drives, trying to get it work before worrying about whether or not it's less than 2 or 3):

Global $Drives[5] = ["1","2","3","4","5"]
$Drives = DriveGetDrive("Fixed")
If $Drives[0] < 4 Then
    $Drives[4] = "None"
EndIf

For some reason, when I run that code, it flips it's lid about being outside my subscript range. I added the ReDim command to resize it back to 5, but that still doesn't work. Now if I set it when I initialize it, it's fine, and I can edit it all I want to manually, just not with DriveGetDrive.

Current modified code:

Global $Drives[5] = ["1","2","3","4","5"]
$Drives = DriveGetDrive("Fixed")
If $Drives[0] < 4 Then
  ReDim $Drives[5]
    $Drives[4] = "None"
EndIf

What I would like to do is resize the Array to fix the amount of drives I have, i.e. if I have 2 drives, make it 3 slots big, [0] for the count it generates, [1] for drive 1, [2] for drive 2, etc. and if it doesn't get a reply from slots 3 and 4, disable those checkboxes/remove the entry from the dropdown list. But that is further complicating the issue as it is, just want the basic premise to work.

If anyone has any ideas for this little issue, I'm welcoming the ideas.

hackersarchangel,

No need to ReDim the array - the function returns a suitably sized array for you automatically, so there is no need to check its size:

Global $Drives = DriveGetDrive("Fixed")

Once you have the array, you can run a loop For $i = 1 To $Drives[0] to create your checkboxes/combo list.

Ok so I was doing it right, as far as grabbing the variable. So use a For-Next loop to make the boxes that way, so it doesn't complain about being outside of the subscript range?

Just making sure I'm understanding this correctly, and that would work.

hackersarchangel,

Using the count element means that you remain within the bounds automatically so you should not have that problem.

But you know where we are if you find something else not working.

That I do You guys have always been helpful

Ok I'll try this when I have a minute today, have some other things going on.

Request thread be closed, going to start a thread about the project in general asking if anyone wants to contribute to the project in an Open Source form.
