The information in this article applies to:
When 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.
When 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 Expression
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. Additional reference words: FoxDos FoxWin 2.00 2.50 2.50a window KBCategory: kbdisplay kbui KBSubcategory: FxtoolSbuilder
