Hello ! I am trying to develop a systray application using MFC. NOTE: I am beginner. I performed that application sucessfully, therefore, when I run the program I can see the icon on the systray, but, I also see the dialog window open as well. When the program runs the following lines: CTrayIco dlg; m_pMainWnd = &dlg; int nResponse = dlg.Modal(); the dialog windows appears, and I don't want to show it. I tried to delete these lines, but, the program didn`t run fine. I would like to put the icon on the systray as soon as I run the program without any dialog window. How can I do that ? Thanks in advance.
