Displaying Unique Messages for Prompts in a Button SetID: Q104347 2.00 2.50 2.50a | 2.50 2.50a MS-DOS | WINDOWS kbdisplay kbui The information in this article applies to:
SUMMARYWhen you are creating a button set in the Screen Builder with two or more push button prompts, you can have a unique message displayed for each individual prompt when it is activated. MORE INFORMATIONWhen a button set is created in FoxPro, a single @ ... GET command is generated, regardless of the number of prompts in the set. Therefore, only a single MESSAGE clause can be used with a button set. However, the MESSAGE clause is reevaluated each time the value of _CUROBJ changes, allowing for the display of unique messages for prompts in the same button set. To do this, declare the MESSAGE clause as either a procedure or an expression. The following code examples demonstrate these methods using a button variable named "choice" with three push button prompts. MESSAGE Clause as a Procedure button_num=(_CUROBJ+1)-OBJNUM(choice)
DO CASE
CASE button_num=1
RETURN "Message text for first button"
CASE button_num=2
RETURN "Message text for second button"
CASE button_num=3
RETURN "Message text for third button"
ENDCASE
MESSAGE Clause as an Expressionchoice_msg((_CUROBJ+1)-OBJNUM(choice)) where DIMENSION choice_msg(3) choice_msg(1)="Message text for first button" choice_msg(2)="Message text for second button" choice_msg(3)="Message text for third button" is in the screen SETUP code to define and initialize the choice_msg array.
