SYMPTOMS

In Visual FoxPro 5.0x, moving between pages in a PageFrame using an ARROW key ignores the NODEFAULT keyword in the Deactivate Event of a page. Moving between pages using a mouse click with the NODEFAULT keyword in the Deactivate Event works as expected.

STATUS

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

MORE INFORMATION

Steps to Reproduce Behavior

Create a Form (TEST.SCX) with a two-page PageFrame.
Type in NODEFAULT in the Deactivate Event of the first page.
Save and run the Form (TEST.SCX).

NOTE: Ensure that the focus is on the first page, then try to move to the second page by using the RIGHT ARROW key. The focus is set to the second page.

WORKAROUND

Here is a workaround for the behavior illustrated in the above example:

Set the Form KEYPREVIEW property to .T.

Put the following code in the KeyPress Event of the Form:

      IF THISFORM.ACTIVECONTROL.BASECLASS="Page" AND ;
         (nKeyCode=4 OR nKeyCode=19) AND ;
         !THISFORM.ACTIVECONTROL.DEACTIVATE()
            NODEFAULT
      ENDIF

Type in the following code in the Deactivate Event of first page:
```
      NODEFAULT
      RETURN .F.
						
```
