Create Powershell form where button makes text to speech-CodePudding

I'm trying to combine two different things in PowerShell that I have no experience with. Creating a form and text to speech. For the text to speech, I've verified that this will talk to me:

Add-Type -AssemblyName System.speech

$speak = New-Object System.Speech.Synthesis.SpeechSynthesizer
$speak.Speak('My test speech')

In my Google searches, I've found some info on creating text boxes. As an example, this will create a box with just a cancel button:

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

    $form = New-Object System.Windows.Forms.Form
    $form.Text = 'Data Entry Form'
    $form.Size = New-Object System.Drawing.Size(300,200)
    $form.StartPosition = 'CenterScreen'

    $cancelButton = New-Object System.Windows.Forms.Button
    $cancelButton.Location = New-Object System.Drawing.Point(150,120)
    $cancelButton.Size = New-Object System.Drawing.Size(75,23)
    $cancelButton.Text = 'Cancel'
    $cancelButton.DialogResult = [System.Windows.Forms.DialogResult]::Cancel
    $form.CancelButton = $cancelButton
    $form.Controls.Add($cancelButton)

    $result = $form.ShowDialog()

My hope is to create a button that will read the text I have specified, but I'm struggling to figure that out. I've edited it to this:

    Add-Type -AssemblyName System.speech

    $speak = New-Object System.Speech.Synthesis.SpeechSynthesizer

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

    $form = New-Object System.Windows.Forms.Form
    $form.Text = 'Data Entry Form'
    $form.Size = New-Object System.Drawing.Size(300,200)
    $form.StartPosition = 'CenterScreen'

    $speakButton = New-Object System.Windows.Forms.Button
    $speakButton.Location = New-Object System.Drawing.Point(150,120)
    $speakButton.Size = New-Object System.Drawing.Size(75,23)
    $speakButton.Text = 'Speak'
    $speakButton.DialogResult = [System.Windows.Forms.DialogResult]$speak.Speak('My test speech')
    $form.text = $speakButton
    $form.Controls.Add($speakButton)

    $result = $form.ShowDialog()

When I start this it says "My test speech" before the box pops up, and nothing happens when I click the button. Clearly I'm on the wrong path here, but I'm not sure where the right one is.

CodePudding user response：

You'll want to register an event handler for the button's Click event, which in PowerShell can be done like this:

$speakButton.add_Click({
    $speak.Speak('My test speech')
})

And then remove the assignment to $speakButton.DialogResult

To use a textbox as input, replace the literal string value with a reference to the Text field on the text box control you want to read from:

$speakButton.add_Click({
    $speak.Speak($variableContainingTextBoxControl.Text)
})
