According to MSDN, the SW_HIDE is ignored during the 1st call when the dialog is about to pop up. ShowWindow[^] The first time an application calls ShowWindow, it should use the WinMain function's nCmdShow parameter as its nCmdShow parameter. Subsequent calls to ShowWindow must use one of the values in the given list, instead of the one specified by the WinMain function's nCmdShow parameter. As noted in the discussion of the nCmdShow parameter, the nCmdShow value is ignored in the first call to ShowWindow if the program that launched the application specifies startup information in the structure. In this case, ShowWindow uses the information specified in the STARTUPINFO structure to show the window.

And the reason is: If it worked, then no target window would receive messages. There is a solution for this: To make your application hide to systray.

don't call DoModal until you want it to show.

Override the
OnWindowPosChanging()method with:if (! m_bVisible) // set to false in the dialog's constructor
lpwndpos->flags &= ~SWP_SHOWWINDOW;CDialog::OnWindowPosChanging(lpwndpos);
Just before calling
ShowWindow(SW_SHOW), setm_bVisibletotrue."Normal is getting dressed in clothes that you buy for work and driving through traffic in a car that you are still paying for, in order to get to the job you need to pay for the clothes and the car and the house you leave vacant all day so you can afford to live in it." - Ellen Goodman

Is there any way to update STARTUPINFO structure ? Thanks for your replay
