PowerShell Windows Forms Project

PowerShell Tools
1 
Tool: Visual Studio
Version: 2022.10.0

I’ve created a basic PowerShell Windows Forms Project in visual studio and have added two buttons and a text box to the form. When I click on button 1 I want to exit the app and when I click on button 2 I want to display “hello ” on the screen. Could someone guide me on how to do this please?

2

I have tried using the Exit command inside the $button1_Click function but it doesn’t work and comes up with an unhandled exception.

3

Also, I’m not sure how to get the value of the textbox string into a powershell variable so that I can display the message.

Hi,
how are you importing the form into powershell?
I’m not familiar with basic forms but I use a lot of advanced .xaml forms

and to add a click I use something like:

Function stop-program
{
      $Form.Close()
      exit
}

$TestButton1.Add_Click({ stop-program })

for the textboxes I use

$MyVariable = $MyTextbox.Text

hope this helps

@Fred , I’m not importing into Powershell but created a new project from scratch in Visual Studio.

I tried your suggestion but it still comes up with an error:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

@Fred , are there any samples of the advanced .xaml forms available?
