I would suggest putting the exe in the startup folder either in the Start menu under the startup folder or in the registry. The registry path is as follows:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

That will start it when the user logs on. Then, have the application start hidden (Form.Visible = false). When it is time, make the application visible again.

thanks for reply.I have the application but how can i periodically visible and invisible the application .will you plz show some syntax.thanks – shamim May 08 '11 at 04:24
If you are using Winforms, just do a this.visible = false; when you want to hide the form. To show it again, set it to true. – IAmTimCorey May 08 '11 at 04:28
i work on winform.I write this.visible=false on from constructor,But form become visible,But if i write under the button event it's become invisible.Why this occur – shamim May 08 '11 at 04:43
Add the code under the form_Loaded event. This will ensure that everything else the form is doing in the background is complete before your code runs. – IAmTimCorey May 08 '11 at 04:45
On the main form, create a Load event. In that event, put the code "this.Visible = false;" – IAmTimCorey May 08 '11 at 05:17

To write to the registry from C#, here is a good link: http://stackoverflow.com/questions/5927152/way-to-write-on-registry-location If you want to do it manually, you can create a reg file and then run it on the target machine. – IAmTimCorey May 08 '11 at 16:01

using System.Windows.Forms;

namespace HideWindows
{
    public class HideForm : Form
    {
        public HideForm()
        {
            Opacity = 0;
            ShowInTaskbar = false;
        }

        public new void Show()
        {
            Opacity = 100;
            ShowInTaskbar = true;

            Show(this);
        }
    }
}

Have you considered converting the application to a windows service? If you did this, you could have it run in the background automatically without any need for user interaction.

The problem with a service is that it shouldn't interact with the user (big no no). – IAmTimCorey May 08 '11 at 04:14
@BiggsTRC agreed.. my thought was that the service would act more as a *dispatcher* with a separate UI used to manage it. It would also be possible to create a desktop application that did not appear on the task bar or notification area, but management becomes difficult. – Bobby D May 08 '11 at 04:16
