Output the Powershell Results to RichTextBox
Thanks for the help in advance
I have a Powershell Form with multiple buttons that call separate functions. These functions will perform a series of tasks
What I cannot seem to get working is for the results of the execution (errors and all) to display into my Outputbox text box.
Instead it goes into the powershell console used to start the application, tried all the methods I could find on the internet, but I'm obviously mis-understanding how to do this.
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") #loading the necessary .net libraries (using void to suppress output)
$form = New-Object System.Windows.Forms.Form
$form.Text = "Azure Environment Build"
$form.Size = New-Object System.Drawing.Size(850,675)
$form.StartPosition = "CenterScreen"
#################################################################################################################################################################################################### Start functions
function Test-Variables {
$Outputbox.Appendtext = ($InputJSON)
#$Outputbox.AppendText = $ResourceINF

#$Outputbox.AppendText = $Location

#$Outputbox.Appendtext = New-AzureRMResourceGroupDeployment -Name deployment -ResourceGroupName $ResourceINF-NET-01 -TemplateFile -Verbose
}

You are not interacting with the GUI TextBox in your functions. The literal Write-Host will use the PSHost console in any case.
One thing I found useful to make such things work however, is to declare an alias:
function Out-Gui($s) {
$OutbutBox.AppendText($s);
}
Set-Alias -Name Write-Host -Value Out-Gui -Scope Global
This avoids quite a bit of copypasta (the WinForms construction is quite windy already), and allows the functions/scripts to remain unchanged between CLI and GUI usage. (- I got a more elaborate Out-Gui function for WPF, btw.)
To capture errors, you must implement try/catch blocks, a TRAP, or capture an -ErrorVariable still. Overriding Out-Default and streams is not quite as trivial.
