{c#} form's events question {intresting !}

[akshaycjoshi]

I am making on application which reduces to a NotifyIcon when minimised and again comes into existence when the NotifyIcon is double clicked.

Here is the code that works

namespace formspractice
{
    public partial class mainform : Form
    {
        public mainform()
        {
            InitializeComponent();
        }

        private void mainform_Resize(object sender, EventArgs e)
        {
            if (this.WindowState == FormWindowState.Minimized)
            {
                Hide();
                notifyIcon.Visible = true;
                notifyIcon.ShowBalloonTip(3);
                
            }

        }

        private void notifyIcon_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            notifyIcon.Visible = false;
            Show();
            WindowState = FormWindowState.Normal;



        }

        private void mainform_FormClosing(object sender, FormClosingEventArgs e)
        {
            notifyIcon.Visible = false;
        }


    }
}

look at the series of calls in the Doubleclick event handler
Show();
WindowState = FormWindowState .Normal;

if i change it to
WindowState = FormWindowState .Normal;
Show();

Than i can see something maximizing but it's not showing.I guess it is not able to paint itself.

Refresh() also not working
Why is this ???

[Plater]

I think you should set the WindowState before calling Show()

[akshaycjoshi]

why is it so ?
it's not working !

[Plater]

Have you set a breakpoint and see where the code execution goes?
It might be moving in a path you did not think it would go.

[akshaycjoshi]

It is going exactly the way it should !
I can see that form maximizing from the taskbar button but it's not showing as if it can not get painted.

[akshaycjoshi]

If i make it maximised as

        private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
        {
             this.WindowState = FormWindowState.Maximized;
            notifyIcon1.Visible = false;
            this.Show();
       }

Then it is showing !

[Plater]

So then it works ?

[akshaycjoshi]

WindowState = FormWindowState .Normal; is still not working.
But WindowState = FormWindowState .Maximised is working.

(both done when we double click the notify icon)

Plater why dont u do it urself, it's a short code.
Maybe then u will have a better analysis of what is happening.

[Plater]

Just did and it works fine for me

[akshaycjoshi]

Please post your entire code

[Plater]

I am thinking in your case the window is being restored, but being restored "under" any other windows you have oppened.
I made the changes to force it to reshow on top.

[code=c#]
private void MainWindow_Resi ze(object sender, EventArgs e)
{
if (this.WindowSta te == FormWindowState .Minimized)
{
this.Visible = false;
}
}
private void ni1_MouseDouble Click(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Le ft)
{
this.Visible = true;
//These lines are used to make sure you window restores over other windows
this.TopMost = true;
Application.DoE vents();
this.TopMost = false;
//
this.WindowStat e = FormWindowState .Normal;
}
}
[/code]

[akshaycjoshi]

what do u mean by "under" any other windows ?

[Plater]

If you have other windows open when you restore the window (set visible=true and the window state = normal) it will often appear to have shown and then hide itself again.
What really happened was the window was drawn, then moved behind whatever other windows might have the focus.
If you minimize every single window you have, then double click your notifiy icon, you should see your window popup, but NOT have the focus.

[Curtis Rutland]

Does toggling the TopMost property back and forth like that always bring the form to the front and let it keep the focus?

I have been using the Win32 API to do that:

[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool SetForegroundWindow(IntPtr hWnd);
......
SetForegroundWindow(this.Handle);

But if your way works, that seems to be less work.

[akshaycjoshi]

so why it is working without such "settings" when I do
this.WindowStat e = FormWindowState .Maximized; ?

I mean I dont have to toggle it then.
