textbox not showing all actions on add_click, only the last one.

PowerShell Help

My problem with this script is that $ResultsTextBox only shows the last item I select/deselect. So if I select to install all software, $ResultsTextBox will only show “removing visual studio code”.

 

I want it to show output for all selected/deselected software.

Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName System.Drawing

$software1 = "7-Zip"
$software2 = "Notepad++"
$software3 = "Visual Studio Code"

$software1status = Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where {$_.DisplayName -like "*$software1*"}
$software2status = Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where {$_.DisplayName -like "*$software2*"}
$software3status = Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where {$_.DisplayName -like "*$software3*"}

There is a better way to achieve your requirement; however, regarding your issue you should append the value every time…

[pre]

$ResultsTextBox.Text += “installing 7-zip”

[/pre]

Thank you.

Thanks for your reply, that actually worked.

The only problem is that it kind of puts everything on the same line Is there a way to make it so it goes to a new line for each software installation?

 

Thanks

$ResultsTextBox.Text += “installing 7-zip `r`n”

 

just be aware, that you should clear the contents on each run, otherwise, you’ll just keep appending into the text.
