ALERT


ALERT ( message {; okButtonTitle} )

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

Description

The ALERT command displays an alert dialog box composed of a note icon, a message, and an OK button.

You pass the message to be displayed in the parameter message. This message can be up to 255 characters long. However, 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.” To change the title of the OK button, pass the new custom title into the optional parameter okButtonTitle. If necessary, the OK button width is resized toward the left, according to the width of the custom title you pass.

Tip: Do not call the ALERT 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.

 String(Records in selection([Parts])))
