MessageBox

In a ScriptoForm, a MessageBox displays a message window, also known as a dialog box, which presents a message to the user. For example, the ScriptoForm may use a MessageBox to notify the user that action has completed or that an error has occurred.

Examples

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Application]::EnableVisualStyles()

# Show informational icon
[void][System.Windows.Forms.MessageBox]::Show(
    "This is a test.",
    "Title",
    [System.Windows.Forms.MessageBoxButtons]::OK,
    [System.Windows.Forms.MessageBoxIcon]::Information
)

# Show warning icon
[void][System.Windows.Forms.MessageBox]::Show(
    "This is a test.",
    "Title",
    [System.Windows.Forms.MessageBoxButtons]::OK,
    [System.Windows.Forms.MessageBoxIcon]::Warning
)

Notes

The System.Windows.Forms assembly must be loaded prior to using a MessageBox.
