I developed an EXE (VB.NET) which is called by a COOL:Plex program. Now I got the following job: if something specific happens "send a windows message with number 42" because that let's e.g. refresh a TreeView (in that COOL:Plex program). My question now is: how can I do that? I have no idea because I never worked with windows messages before (not in C neither in VB 6.0).

Thx

If you're using VB6, you can use the SendMessage Win32 API function.
If you're using VB.Net you should post the question over at our sister forum www.dotnetforums.net
