Piping information from text box - powershell

Question

I have a script that requires input from the user in a textbox. Once the user hits enter or clicks OK the data in the textbox must be transferred to a command. Here is the textbox portion of the code. I am just a couple months in to PS. Feel free to criticize :)
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
$objForm = New-Object System.Windows.Forms.Form;
$objForm.Text = "Enter Patch Number";
$objForm.Size = New-Object System.Drawing.Size(100,100);
$objForm.StartPosition = "CenterScreen";
$InputBox = New-Object System.Windows.Forms.TextBox
$InputBox.Location = New-Object System.Drawing.Size(20,50)
$InputBox.Size = New-Object System.Drawing.Size(150,20)
$Form.Controls.Add($InputBox)
$Button = New-Object System.Windows.Forms.Button
$Button.Location = New-Object System.Drawing.Size(400,30)
$Button.Size = New-Object System.Drawing.Size(110,80)
$Button.Text = "Send to Patch Command"
$Button.Add_Click({$version})
$Form.Controls.Add($Button)
$wks=$InputBox.text
.\anp deploypatch -patch=$version
$Form.Add_Shown({$Form.Activate()})
[void] $Form.ShowDialog()
This is the command that must have the user input piped to the end. An example of this cmd being executed correctly is...
.\anp deploypatch -patch=437.1237
In other words, the user types in the item in bold above and hits enter and the command is executed based on the version the user inputs. Main thing I want here is how to xfer the users input in to my desired command.

You can try the following code. In your original code $form does not exist, the control position were random, and the enter key was not linked to the button.
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
$objForm = New-Object System.Windows.Forms.Form;
$objForm.Text = "Enter Patch Number";
$objForm.Size = New-Object System.Drawing.Size(200,200);
$objForm.StartPosition = "CenterScreen";
$InputBox = New-Object System.Windows.Forms.TextBox
$InputBox.Location = New-Object System.Drawing.Point(20,20)
$InputBox.Size = New-Object System.Drawing.Size(150,20)
$objForm.Controls.Add($InputBox)
$Button = New-Object System.Windows.Forms.Button
$Button.Location = New-Object System.Drawing.Point(50,50)
$Button.Size = New-Object System.Drawing.Size(110,80)
$Button.Text = "Send to Patch Command"
$Button.Add_Click({$objForm.Close()})
$objForm.AcceptButton = $Button # the button is linked to the enter key
$objForm.Controls.Add($Button)
$wks=$InputBox.text
$objForm.Add_Shown({$objForm.Activate()})
[void] $objForm.ShowDialog()
$version = $InputBox.Text
#$version
.\anp deploypatch -patch=$version

The below seems to do the trick let me know how you get on.
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
$Form = New-Object System.Windows.Forms.Form;
$Form.Text = "Enter Patch Number";
$Form.Size = New-Object System.Drawing.Size(500,200);
$Form.StartPosition = "CenterScreen";
$InputBox = New-Object System.Windows.Forms.TextBox
$InputBox.Location = New-Object System.Drawing.Size(20,50)
$InputBox.Size = New-Object System.Drawing.Size(150,20)
$InputBox.text = ""
$Form.Controls.Add($InputBox)
$Button = New-Object System.Windows.Forms.Button
$Button.Location = New-Object System.Drawing.Size(400,30)
$Button.Size = New-Object System.Drawing.Size(110,80)
$Button.Text = "Send to Patch Command"
$Button.Add_Click({patch})
$Form.Controls.Add($Button)
Function patch {
$wks=$InputBox.text
Invoke-Expression "\anp deploypatch -patch='$wks'"
}
$Form.Add_Shown({$Form.Activate()})
[void] $Form.ShowDialog()
