System Tray Icon

It isn't necessary to use an OCX in VB5.  A simple API call to ShellNotifyIcon  in a .bas module can do the same thing without the overhead of the OCX.  It is also FREE.

SteveB:
This ocx is freeware.  Also, to use API for placing and controlling tray icons is possible, but you need callbacks and generally more code than is necessary.  Why reinvent the wheel?

I use the following code - downloaded from http://www.sourcesite.simplenet.com/Frames.html

'You may use this BAS file as much as you want as
'long as you leave all the contents in it..

'For starters to make this work you need to do one thing.
'Create a menu called mnuSystemtray.  Create as many options
'you want under it.  This will be what pops up when they right
'click on the icon while it's in the system tray..  After you have
'created this menu then make sure that it is invisible and
'that's all there is too it..

Thanx. The OCX works fine for me.
