Hi,

I'd like to use a powershell script within PS Studio as well as outside. I'd also like to write the output in the normal script to write-host (or verbose), in powershell studio to $richtextboxlogging.text).
Therefore I use $LoggingPSStudio. It works for write-host but not for $richtextboxlogging.
Below the code, please advise howto correct.

Code: [Select all] [Expand/Collapse] [Download] (Untitled.ps1)

1. $output = if ($LoggingPSStudio)
2.     {
3.       '$richtextboxLogging.Text ='
4.     }
5.     else  
6.     {
7.       'Write-Host'
8.     }
9.      
10.     #region executing computer checks  
11.     if ($ComputerPerformance -or $All)
12.     {
13.       & $output 'Getting Uptime'
14.       $Uptime = $(Get-Uptime -ComputerName $ComputerName)

If I'm not mistaken, you want the output to go to $richtextboxlogging if $LoggingPSStudio is true, correct? If this is the case, I'd write a small function like so and just call it when you need to send output:

Code: [Select all] [Expand/Collapse] [Download] (Untitled.ps1)

1. function Write-Message {
2.   param
3.   (
4.     [Parameter(Mandatory = $true,
5.            Position = 0)]
6.     [String]$Message,
7.     [Parameter(Position = 1)]
8.     [boolean]$LoggingPSStudio
9.   )
10.    
11.   if ($LoggingPSStudio) {
12.     $richtextbox1.Text = $Message
13.   } else {     
14.     Write-Host $Message
15.   }
16.    
17.    
18.   #TODO: Place script here
19. }
20.  
21. if ($ComputerPerformance -or $All) {
22.   Write-Message -Message 'Testing, testing' -LoggingPSStudio $false
23.   $Uptime = $(Get-Uptime -ComputerName $ComputerName)
24. }

Thanks but I don't want to change every command in my script to write-mesasge -message 'mymessag" -loggingpsstudio $false or $true
I'd like to have my script get-comptuterreport to be with options -writehost or -loggingpsstudio.

The comments in the script then just would be write-message 'Mymessage', I'd then only have to do a find replace of write-host -text by write-message -message
Sounds more flexible to me. Could you advise on that?

In you form place a simple function that is a wrapper for write-host at the script scope.

Code: [Select all] [Expand/Collapse] [Download] (Untitled.ps1)

1. function Write-Host{
2.     Param($message)
3.         $richtextbox1.AppendText($message)
4. }

When not in the form Write-Host or Write-Verbose will behave as usual. In a form the wrapper function will intercept the function call and output as you like.

Attached is a simple demo of how to do this.

We can actually write all parameters to both locations at the same time and account for extra parameters not used in the GUI.

Code: [Select all] [Expand/Collapse] [Download] (Untitled.ps1)

1. function Write-Host {
2.     param (
3.         [Parameter(Position = 0, ValueFromPipeline = $true, ValueFromRemainingArguments = $true)]
4.         [System.Object]${Object},
5.         [switch]${NoNewline},
6.         [System.Object]${Separator},
7.         [System.ConsoleColor]$ForegroundColor,
8.         [System.ConsoleColor]${BackgroundColor}
9.     )
10.     $textbox1.Lines += $Object
11.     Microsoft.PowerShell.Utility\Write-Host @PsBoundParameters
12. }

Thanks but both result in an error when used outside PS Studio (PS ISE):

You cannot call a method on a null-valued expression.
At c:\MyScripts\Powershell\HealthCheck\HealthCheck.ps1 char:9
+ $richtextbox1.AppendText($message)


Write-Host : The property 'Lines' cannot be found on this object. Verify that the property exists and can be set.

Did you run the example I posted above?

[stevens]

I did, but honestly, I don't get it.

What is it that you don't get?
