Hide form on startup?

[NeedHelp]

How do you hide form1 on startup? I have an application where I have a notifyicon and don't want to display the main form (although the notifyicon is in the form1 on load). I used

this.visible = false;

which did not work at all. I know this can be done in C++ (I think).

Also, when I minimize my form on startup it shows up minimized above the start button. This is if I have the "show in taskbar" set to false.

Any ideas?

I've seen this problem before. You can do this:

On Form Load:

this.opacity = 0;

and then when you want to display it

this.opacity = 1;

You could do this.WindowState = WindowState.Minimized, which will minimize the form, but show it in the taskbar. By setting this.ShowInTaskbar to False, you'll get rid of the task, but it can still be gotten to via Alt-Tab.

The better way to do this would be to use a void Main() as a startup. Then, you can either just show the TrayIcon, or control what forms are shown.

This is what I had originally and it shows a little box above the start button. Looks really bad like a minimized form in an MDI.

How do I use void main as startup?

The little box above the start button sounds like an OS/shell problem - that shouldn't happen.

You can switch to void main() as your startup method in the Properties of the Project, I believe.

I was able to replicate the program just now. Not sure why it shows a little box there but if you follow the steps above that will happen. If you set the form to minimized in the properties it will not show but if you return it to normal it shows as the box instead of showing the "normal" state form.

Not sure if this is a bug or what. I'd go with brackett's suggestion and switch it to void main().

I always thought that the this.visible = false would hide the form. Is this not true?
