I have a dialog box with several entry boxes.  The valid values
are a range of numbers.  Upon receiving EN_KILLFOCUS, I want to
pop up a message box if the entered value doesn't meet the
requirements and return the focus to the offending entry box. 
I can get the message box to pop up, but WinSetFocus doesn't
return the focus to the offending entry box.  I'm using the
code from the QuickHelp example that calls WinSetFocus
immediately after WinMessageBox from within the EN_KILLFOCUS
handler.  What am I doing wrong?  The focus just goes to the
next control (whatever the user selected).
