PowerShell: How to display arrays in CheckListBox - arrays

Question

I'm trying to make arrays which lead to different files on my computer. Then I want to display the arrays in a check box, so I can just click and open my files from there.
The array can be static, but would be nice if I could add new stuff dynamically.
$menulist.DataBindings.DefaultDataSourceUpdateMode = 0
$menulist.FormattingEnabled = $True
$System_Drawing_Point = New-Object System.Drawing.Point
$System_Drawing_Point.X = 12
$System_Drawing_Point.Y = 24
$menulist.Location = $System_Drawing_Point
$menulist.Name = "menulist"
$System_Drawing_Size = New-Object System.Drawing.Size
$System_Drawing_Size.Height = 328
$System_Drawing_Size.Width = 235
$TemplateArray = $template1,$template2;
$template1 = Get-ChildItem -Path C:\Users\$Env:USERNAME\Documents\test.tx
$template2 = Get-ChildItem -Path C:\Users\$Env:USERNAME\Documents\test2.txt
$menulist.Items.AddRange($TemplateArray)
$menulist.Size = $System_Drawing_Size
$menulist.TabIndex = 7

While we are still discussing what you need, I'll take a guess:
$TemplateArray = $template1,$template2;
$template1 = Get-ChildItem -Path C:\Users\$Env:USERNAME\Documents\test.tx
$template2 = Get-ChildItem -Path C:\Users\$Env:USERNAME\Documents\test2.txt
Notice above - $template1 and $template2 are used before they are declared. You probably get two empty strings in it. Instead, initialize variables first:
$template1 = Get-ChildItem -Path C:\Users\$Env:USERNAME\Documents\test.tx
$template2 = Get-ChildItem -Path C:\Users\$Env:USERNAME\Documents\test2.txt
$TemplateArray = $template1,$template2;
