Description

Displays a message box with an OK button.

Call ShowMessage to display a simple message box with an OK button. The name of the application's executable file appears as the caption of the message box.

ShowMessage parameters are described below:

• Msg parameter is the message string that appears in the message box.
• TaskDlgFlags parameter is a set of flags, allowing to control a dialog behavior. The supported options are tfAllowDialogCancellation, tfSizeToContent, and tfRtlLayout. The default TaskDlgFlags is an empty set.

Note: The original ShowMessage uses tfAllowDialogCancellation as default, and under Right-to-left script tfRtlLayout is added. No other default options are added.

Note: To display a message in a message box with other buttons or icons, use the MessageDlg function.

Note: If the user types Ctrl+C in the message box, the text of the message is copied to the clipboard.
