Re: Why doesnt this work - C# Discussion Boards

I have a Windows application and I was doing something that I thought to be very simple. The ONLY change that I made was:

<br />
		/// The main entry point for the application.<br />
		/// </summary><br />
		[STAThread]<br />
		static void Main() <br />
		{<br />
			Form1 someForm = new Form1();<br />
			someForm.Visible = false;<br />
			Application.Run(someForm);<br />
		}<br />

This didnt work. I dont know what I am doing wrong; I would have thought that that was a pretty good way to make it invisble but Im wrong.

Thx,
Jim

You need to make changes to your form in your onload or constructor...not in the Main.

Thanks a lot, but sadly I tried that too with no result Frown | :(

More exactly, this was the code that I used:

<br />
		public Form1()<br />
		{<br />
			this.Visible = false;<br />
			InitializeComponent();<br />
		}<br />

I also tried

<br />
		public Form1()<br />
		{			<br />
			InitializeComponent();<br />
                        this.Visible = false;<br />
		}<br />

What about the Form's Load method? That was the other suggestion, did you try that?

Application.Run(Form f) sets the form's Visible attribute to True internally when it's starting the message loop for the form, so your form gets displayed regardless of what you set Visible to.

To hide the form from the user you can either set its size to (0,0) or move the form off-screen (or both).

Thanks, I didnt know about that side effect! This program is going to be run as a scheduled task, how do I go about stopping it from stealing focus?

Thanks a lot,
Jim

You don't have to show a form for your program to run and perform its tasks.
Take a look at the other Application.Run() overloads, that could be the cleaner solution.

Otherwise you'd have to p/invoke ShowWindow(), there you can specify to show a window without giving it focus.

Good post, I tested this out after posting to him earlier and saw that my suggestion wouldn't help. I was curious as to why it wouldn't hide as well.

Hi!!

Does anyone know how I can use a normal image as a cursor?
I have seen I can load a .cur file, but do you know if I can do it from a .gif or .jpg?
If not, do you know how I can create a .cur file from another kind of image file?

Thanks.
