I have a script that performs an arithmetic function. I'd like for the script to refresh itself-CodePudding

My script takes in 3 number inputs and performs functions accordingly. For now I need to stop the entire script and re-run if I have new numbers to input. How can I use the same session to enter new numbers?

CodePudding user response：

You can simplify it by adding the labels to the main Form only once outside the .Add_Click event, then inside the event you can do your calculation and update their .Text property. This example demonstrates how to do it for the "Bullish Pattern" tab and you can do the same, following this example, for the "Bearish Pattern" one:

# Both labels are now outside the Event!

$dBullLabel = [Windows.Forms.Label]@{
    Text      = ''
    Location  = [Drawing.Point]::new(230, 50)
    Font      = [Drawing.Font]::new("Microsoft Sans Serif", 12, [Drawing.FontStyle]::Bold)
    AutoSize  = $true
}

$dcalcLabel = [Windows.Forms.Label]@{
    Text     = ''
    Location = [Drawing.Point]::new(280, 70)
    Font     = [System.Drawing.Font]::new("Microsoft Sans Serif", 12, [Drawing.FontStyle]::Bold)
    AutoSize = $true
}

$main_form.Controls.AddRange(@($dBullLabel, $dcalcLabel))
$TabPage1.Controls.AddRange(@($dcalcLabel, $dBullLabel))

$bullCalculateButton.Add_Click({
    # Inside the event, we do just calculation
    $pointD = [double] $aBullTextbox.Text - $bBullTextbox.Text - $cBullTextbox.Text
    # and update
    $dBullLabel.Text = "Point D will be at:"
    $dcalcLabel.Text = $pointD
})
