Hello All,

Is it possible to add some picture or logo in Excel main window
background ? I found many tutorials on Internet but all regards excel
sheet or workbook background but I mean Excel application main window
background not workbook . How achieve it ?

Basically.., NO! Excel is a MDI application and so when no files are
open there is nothing in the 'main window' to display. The only way to
change the background of the application window is to ask MS to build
this option into Excel (or MS Office in general), like they did with the
application 'skin' color. I've seen this in some apps where we can
customize (entirely or partially) the UI with available options/tools.



Technically speaking XLMAIN and XLDESK are registered classes and it
should be possible to change background using WINAPI.
