Hi, I am working with the secured form( server form) when the form is closed, the form is unloaded, the application still remains in the task manager. when i click the application icon in the system tray it will ask for the password which is another form. When i give the password it go to the server form. What my Query is when i try to open the second instance it should ask for the password form. It just interpret like yahoo messenger.Try to close the application It is not closed it exists in the systray or some place. When we try to open it again it opens the previous instance. I need the same. If anyone knows please give me the way to work. Thanks in advance , With regards Jose.
