This might be a pretty simple question but I'm totally lost and searching for an answer hasn't been helpful.
I've got some powershell code to display a simple GUI with TextBoxes. Some of the textboxes allows the user to press Enter to run Button_Click code. When I try running the PS1 script, I get errors saying the following:
Unable to find type [System.Windows.Forms.KeyEventHandler].
Make sure that the assembly that contains this type is loaded.At C:\Scripts\GUI-Testing.ps1:161 char:1
$TestVar=[System.Windows.Forms.KeyEventHandler]
CategoryInfo : InvalidOperation: (System.Windows.Forms.KeyEventHandler:TypeName)
FullyQualifiedErrorId : TypeNotFound
The strange part, if I close the GUI then re-run the script, I don't get the Unable to find type error and pressing Enter works as desired.
Thinking I had an answer, I tried using [void][reflection.assembly]::Load('System.Windows.Forms.KeyEventHandler') which give this error Exception calling "Load" with "1" argument(s): "Could not load file or assembly 'System.Windows.Forms.KeyEventHandler' or one of its dependencies. [FileNotFoundException]
Make sure you load the following assemblies at the top of your script:
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
If it's still not working, you could do something like:
$objForm.KeyPreview = $True
$objForm.Add_KeyDown({
if ($_.KeyCode -eq "Enter")
{
#Write Code Here
}
})
