Keeping Variables in external file

[jvierra]

Example:

+++ PS1 file vartest.ps1 +++
$global:myvar1 = 'hello;
++++ end +++

At PS prompt:
rv myvar
. .\vartest.ps1
$myvar

The result "hello" will be printed.

? this is just basic powershell.
Of course I'm talking about using PS variables in PS Studio. There, it does not work (using scriptpath, dotscouring the ps1, then loading the variable in f.e. a textbox $textbox1.text = $variableofps1

[jvierra]

No idea what you are trying to say. There is nothing different about a form. PSS doesn't change that unless there is a bug in the loading. This would then cause an error. You cannot load anything in a job and have it available outside of the job.

I'm not talking about a job. I'm just trying loading variables out of an (not PS studio) external file (txt, ps1, psm1, xml does not matter). This so I can share my form in the open and users can fill in their variables like $domain = 'ourdomain', $smtpserver = 'oursmtpserver' etc. It works fine with a txt file then

$textdata = Get-Content "$ScriptDirectory\globalvariables.txt"
$GlobalVariables = $TextData | ConvertFrom-StringData
but then I'm really limited with the textfile whereas with a ps1 I could clearly document what each variable means and keep it better organized. The txt-file has lots of limitations like f.e. share = \\\\server\\share\\...

I'll upload an example of what I mean if this is not clear.

Well I be damend.
Example in att. works ....

But it does not in my form.
It DOES when I use
cd $ScriptDirectory\
.\GlobalVariables.ps1

but when I use . "$ScriptDirectory\GlobalVariables.ps1" it says it cannot execute the command. Maybe my path is to long?

The following works fine for me:

Code: Select all

	$form1_Load={
		$scriptpath = if ($hostinvocation) {
			Split-Path $hostinvocation.MyCommand.path
		} else {
			Split-Path $script:MyInvocation.MyCommand.Path
		}
		. $scriptpath\myvariables.ps1
		$textbox1.Text = $global:myvar
	}

[jvierra]

This also works for me with no issues:

Code: Select all

$form1_Load={
	$textdata = Get-Content $ScriptDirectory\variables.txt |
		ConvertFrom-StringData |
		ForEach-Object { New-Variable -Name $_.keys -Value $_.values -Scope Global }
	
	. $ScriptDirectory\variables.ps1
	
	$textbox1.Lines = $sccmserver, $smtpserver
	$textbox2.Lines = $sccmserverps1, $smtpserverps1
	
}

Your code works for me as long as the "globalvariablestest.ps1" file is in the correct directory and is named correctly. If the file is not named correctly an error occurs which says that the term is not recognized as the name of a cmdlet, function, script, file, or operable program.

[jvierra]

The file must be named correctly and be in the script folder. That is the whole point of this thread.

If you have an issue that is different please open a new question with a clear statement of your issue.

Thanks for your input guys. Figured it out meanwhile!
