I have it ALMOST working. In fact, I'm down to one problem. The icon for the notification window doesn't display. I downloaded the program Tray from the archive and copied all of the code. I even took the res files from the tray program and used them in my own program. An area in the Taskbar notification area clears when the program loads, moving the mouse to this blank area lets me see the program hint, and clicking on this blank area gets me a popup that I can use to display the main window, or to close and exit. All works except NO ICON. Any ideas? TIA Bob Byers wrote: Quote: I'd like to have my program not have a taskbar button and show an icon in the notification area instead.

Gambit You are surely right. LoadImage returns a NULL instead of a handle. But, I just don't see what I've done wrong. I've used the RES files from TrayIcon.Res file from the sample Tray program and copied all of the references exactly as you can see from the code in my last message. I just don't know where to go from here.

OK, then how do I add the resource to the project? This seems to work in the programs that I got from the bcbdev.com faq pages. But, the exact same code doesn't work in mine. This is truly a puzzle to me.

This does of course put you at risk of the infamous resource-file-stops-compilation bug but I got away with it :) I think that I've found a problem here. I looked at the TrayIcon.res file with the Image Editor (I had never used this before) and discovered that the program was using the wrong name for the icon. When I renamed it, the program now puts the icon in the task window. Why the name changed I have no Idea. I do have one question.. there doesn't seem to be a way to copy an icon from an Ico file into the image editor. How do you do this, or do you have to manufacture all new items by hand? The help file doesn't address this.
