Dear friends I do not know how to put it. But I will try and hope u will understand it. I need to develop an application which will keep record of all the to do tasks and status of projects. I want it to run in the background even if the user closes it. Like Yahoo Messanger or some of these type applications which can be used by using icon in the right hand side group on the task bar (I do not know what they call it).

In this way the application will be able to prompt to the user whenever some deadline or a meeting is approaching.

Thanks

Look into making a service.

I don't know whether you can display forms on the DeskTop from a service. But if not, a work-around might be to create a service as well as a separate .EXE. The EXE would interact with the service that has been running the whole time.

You don't necessarily need to create a windows service. What you are looking for is to develop a taskbar tray application. I have used some code from the CruiseControl.NET CCTray application. It has the code needed to run in the task tray as well as some hooks for doing popup "balloon" messages and playing sounds. The CCTray app is part of the larger application of CruiseControl.net, a continuous integration server. You can find it here:

Look on google for notify icon! In .net it's really not that difficult anymore to get what you would like: a notify icon into the system tray.
