Keeping the Cursor from Advancing on Push Button Object

• Microsoft FoxPro for MS-DOS, versions 2.0, 2.5, 2.5a, 2.5b, 2.6
• Microsoft FoxPro for Windows, versions 2.5, 2.5a, 2.5b, 2.6

SUMMARY

When the ENTER key is pressed, it sometimes is desirable to have the cursor stay on the same push button prompt in a set of multiple prompts in a push button object. However, doing this is not as simple as with other GET fields in a screen because FoxPro treats each prompt in a set of push buttons as a separate object, even though the push button set is defined as a single screen object.

This article describes two methods of keeping the cursor from moving to the next field.

MORE INFORMATION

Method 1

1. Open or create a new screen.

2. In FoxPro for Windows, use the Push Button tool to add a push button to the screen. In FoxPro for MS-DOS, choose Push Button from the Screen menu.

3. In the Push Button Prompts dialog box, enter the set of prompts. In FoxPro for Windows, choose the Variable button. In FoxPro for MS-DOS, choose the Choose button under Variable. In the resulting dialog box, type a variable name, for example "m.choice" (without the quotation marks). Choose OK.

4. In the Push Button dialog box, choose the Valid button in FoxPro for Windows. In FoxPro for MS-DOS, choose the Valid check box under Options.

5. In the resulting dialog box, select Procedure, and then enter the CASE statements that you want to have executed. Add the following lines of code immediately after the final ENDCASE statement:

         _CUROBJ = OBJNUM(m.choice)+(m.choice-1)
         SHOW GETS
   

6. Generate and run the screen.

Method 2

1. Follow steps 1-5 above; however, instead of entering the code shown in step 5, add the following lines of code immediately after the final ENDCASE statement:

         SHOW GETS
         RETURN 0
   

2. Generate and run the screen.
