Hello,

I am using a windows form from within powershell. I have a textbox which I
have added to the form that I would like to be able to clear but I am
missing something on how to accomplish this. I want to enter some text in
the textbox then when I click the go button I want the text to be cleared.
What is the syntax for accessing an objects properties?

Thanks

Here is my script:

$objForm = New-Object System.Windows.Forms.Form
$objForm.Text = "MyForm"
$objForm.Size = New-Object System.Drawing.Size(600,400)
$objForm.StartPosition = "CenterScreen"

$objTextBox = New-Object System.Windows.Forms.TextBox
$objTextBox.Location = New-Object System.Drawing.Size(10,40)
$objTextBox.Size = New-Object System.Drawing.Size(260,20)
$objForm.Controls.Add($objTextBox)

$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Size(70,120)
$OKButton.Size = New-Object System.Drawing.Size(100,23)
$OKButton.Text = "GO"
$OKButton.Add_Click({<HERE IS WHERE I WANT TO CLEAR $objTextBox>})
$objForm.Controls.Add($OKButton)

$objForm.Topmost = $True

$objForm.Add_Shown({$objForm.Activate()})
[void] $objForm.ShowDialog()

Hi,

It's as simple as:

$OKButton.Add_Click( { $objTextBox.Text = "" } )

Hope this helps,

You can set its 'text' property to an empty string ....

$OKButton.Add_Click({$objTextBox.Text=""})

That should be an object's members, which includes properties, methods
and events. I'm not sure what you mean exactly, but maybe this helps:

[reflection.assembly]::LoadWithPartialName("System.Windows.Forms")
$objTextBox = New-Object System.Windows.Forms.TextBox
$objTextBox|get-member

You want to do an "action", so you're likely looking for a method. I
looked for a "clear" and there was one and it worked.

> $OKButton.Add_Click({<HERE IS WHERE I WANT TO CLEAR $objTextBox>})

This should work for you:
$OKButton.Add_Click({$objTextBox.clear()})

Thanks everyone,

I am new to powershell scripting and I was simply not referencing the object
correctly. I was using objectTextbox rather that $objectTextbox. Duh....
