CloseQuery

A CloseQuery event occurs when you remove a Window from display (close it).  When you close a window, PowerBuilder queries any active PowerBuilder windows (Child, Popup, and Sheets) to determine the value of Message.ReturnValue.  If the Message.ReturnValue is 1, the window cannot be closed.

To perform some processing or do some checking before you close the window, set the value of Message.ReturnValue to 1 and then write a script for the CloseQuery event to perform the desired processing.  Be sure to set Message.ReturnValue to 0,  so the window can be closed.

SQLPreview (DataWindow only)

An SQLPreview event occurs after a Retrieve, Update, or ReselectRow function call, and immediately before the function is executed.

The SQLPreview event has action codes that specify what action will take place when the event occurs.  You can use the SetActionCode function to set the action code.  The action codes are:

0 - (default) Continue.

1 - Stop processing.

2 - Skip this request and execute the next request.

Note:When the Retrieve function triggers the SQLPreview event, the DataWindow has already been reset.  When the Update function triggers the SQLPreview event, the DataWindow has not been reset.
