Setting form object properties via a forloop

[StupidSexyFlanders]

Not sure if my logic is wrong, or if this is even the proper way to do this. In any regard, it's not working...

I have an array like this:
$names = "$fee","$fii","$foe","$fum"

Then, I create a series of form objects (e.g. labels) with the same names:

$fee = New-Object 'System.Windows.Forms.Label'
$fii = New-Object 'System.Windows.Forms.Label'
and so on....

Then, I try using a forloop:

for($n=0;$n -lt $names.count;$n++)
{
if($something -eq $true)
{
$names[$n].BackColor = 'red'
}
else
{
$names[$n].BackColor = 'green'
}
}

Not sure if this can even be done. Whenever I try, it (predictably) says "$names[$n] does not contain a property called 'BackColor'".

My actual array is pretty big and I am trying to avoid having to manually create a bunch of if statements for each item.mbaker2012-07-09 14:19:40

The problem is the way you are declaring the array: $names = "$fee","$fii","$foe","$fum" In this case you are creating a list of strings instead of labels. Try this instead: $name = $fee, $fii, $foe, $fum David

But $fee equals new-object. When I go through the loop, calling $fee, won't it just try to create another new object and throw an error? I am going to try it and see....

[davidc]

When you put the variable in double quotes it becomes a string. David

Really? I thought that only applied to single-quotes. In any regard, still no dice. I changed my code to read this way:

$names = $fee,$fii,$foe,$fum
$fee = New-Object 'System.Windows.Forms.Label'
$fii = New-Object 'System.Windows.Forms.Label'
(and so on...)

for($n=0;$n -lt $names.count;$n++)
{
if($something -eq $true)
{
$names[$n].BackColor = 'red'
}
else
{
$names[$n].BackColor = 'green'
}
}

Still getting:
"Property 'BackColor' cannot be found on this object; make sure it exists and is settable."

Create the names array after creating the Labels objects otherwise you will have an array of empty (null) values. Just for future reference, ScriptingAnswers forums designated for scripting questions like this. David

That appeared to be the problem. Working like a champ now.
Another rookie mistake FTW!

Thanks!

I will take this type of thing to the other forum in the future. mbaker2012-07-09 16:24:03
