PRB: Execution of REPORT FORM Command Sets Focus to Application

• Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a

SYMPTOMS

Executing a REPORT FORM command while an application is running minimized, sets focus to the application and restores the application's window. After the REPORT FORM command finishes executing, the application loses focus and continues running minimized.

RESOLUTION

Setting the visible property of the form to false before the REPORT FORM command is executed prevents the form from being restored and displayed on screen.

The following code snippet illustrates changing the visible property before and after a REPORT FORM command is encountered. In the example below, this code would appear in the Timer Event method of the timer object.

   ThisForm.Visible=.F.
   REPORT FORM prtsrv FOR RECNO() < 5 TO PRINT NOCONSOLE NOWAIT
   ThisForm.Visible=.T.

STATUS

Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

When an application compiled with Visual FoxPro version 5.0 is running as a minimized background process and a REPORT FORM command is encountered, the application's window is restored from its minimized state and displayed on screen. After the REPORT FORM command has finished executing, the application's window is minimized and the application continues executing as a background process.

Applications compiled with Visual FoxPro version 3.0 that are running as a minimized background process remain minimized when a REPORT FORM command is encountered.

Steps to Reproduce Behavior

1. Using Visual FoxPro version 5.0, create a new project called Prtsrv.

2. Click Data, Databases and add the Testdata database from the VFP\Samples\Data folder.

3. Click Documents, Reports and create a new quick report using the Customer table of the Testdata database. Save the report as Prtsrv.

4. Click Code, Programs and create a new program file named Prtsrv with the following code:

         PUBLIC rollcounter
         rollcounter=0
         DO FORM prtsrv
         READ EVENTS
   

         _SCREEN.WINDOWSTATE=2
         _SCREEN.VISIBLE=.T.
         _SCREEN.SHOW
         ZOOM WINDOW SCREEN MAX
   

5. Set Prtsrv.prg as the main program file.

6. Click Documents, Forms and create a new form called Prtsrv with the following properties:

         AutoCenter = .T.
         Height     = 130
         ShowWindow = 2
         Width      = 192
   
   

7. In the form's Activate event, add the following code:

         _SCREEN.WINDOWSTATE=1
         _SCREEN.VISIBLE=.f.
         HIDE WINDOW SCREEN
         thiswin=WONTOP()
         ZOOM WINDOW &thiswin MIN
   

8. Add a Timer control to the form with the following properties:

         Interval=3000
   

9. Add the following code to the Timer Event method of the timer object:

         rollcounter=rollcounter+1
         REPORT FORM prtsrv FOR RECNO()  < 5 TO PRINT NOCONSOLE NOWAIT
         IF rollcounter=3
         ThisForm.Command1.Click
         ENDIF
   

10. Add a command button to the form with the following code in the Click

        event of the command button:
    

          RELEASE THISFORM
          CLEAR EVENTS
    

11. From the Project Manager, build an executable file. Open Windows

        Explorer and double-click the executable file. At 30 second
        intervals, the Prtsrv form is restored and visible on screen.
