CONFIRM


CONFIRM ( message {; okButtonTitle {; cancelButtonTitle}} )

Parameter	Type	Description
message	String	Message to display in the confirmation dialog box
okButtonTitle	String	OK button title
cancelButtonTitle	String	Cancel button title

Description

The CONFIRM command displays a confirm dialog box composed of a note icon, a message, an OK button, and a Cancel Button.

You pass the message to be displayed in the message parameter. This message can be up to 255 characters long. If the message does not fit into the message area, it can appear truncated, depending on its length and the width of the characters.

By default, the title of the OK button is “OK” and that of the Cancel button is “Cancel.” To change the titles of these buttons, pass the new custom titles into the optional parameters okButtonTitle and cancelButtonTitle. If necessary, the width of the buttons is resized toward the left, according to the width of the custom titles you pass.

The OK button is the default button. If the user clicks the OK button or presses Enter to accept the dialog box, the OK system variable is set to 1. If the user clicks the Cancel button to cancel the dialog box, the OK system variable is set to 0.

Tip: Do not call the CONFIRM command from the section of a form or object method that handles the On Activate or On Deactivate form events; this will cause an endless loop.
