BUG: DEFINE WINDOW in Load Event Does Not Appear

• Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a, 6.0

SYMPTOMS

A form or a formset contains a DEFINE WINDOW command in the Load event. However, the window does not appear when the form runs. The window is in Visual FoxPro's memory.

RESOLUTION

Move the DEFINE WINDOW command from the Load event to the Init event or the Activate event of the form or formset. The behavior of the DEFINE WINDOW command varies depending on which event you choose. The "More Information" section discusses the differences.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

This behavior can occur when transporting FoxPro 2.x screens into Visual FoxPro using the Transport utility. A functional conversion can place a DEFINE WINDOW in the Load event under some circumstances. The following steps also apply if you are using a formset:

Steps to Reproduce Behavior

1. Create a form.



2. Add a command button that has a Caption of "Exit" and that contains the following in the Click event:




CLEAR WINDOW test
ThisForm.Release 

3. Place the following code in the Load event of the form:




DEFINE WINDOW Test ;
   AT  0.000, 0.000 ;
   SIZE 28, 80  ;
   TITLE "This is a test window." ;
   FONT "MS Sans Serif", 8 ;
   FLOAT ;
   MINIMIZE ;
   SYSTEM
MOVE WINDOW Test CENTER 
   ACTIVATE WINDOW Test
@ 1,1 SAY "This is text in the test window." ;
   SIZE 1,80 ;
   PICTURE "@I" ;
   FONT "MS Sans Serif", 8 ;
   STYLE "T"     

4. Save and run the form. Note that only the form appears. Press the EXIT button.



5. Copy the code from the Load event and then comment it out.



6. Place the code in the Init event and run the form. Note that the window created with the DEFINE WINDOW appears behind the form. Press the EXIT button.



7. Copy the code from the Init event and then comment it out.



8. Place the code in the Activate event and run the form. Note that the window created with the DEFINE WINDOW appears in front the form.
