I am trying to close a form EC45 when a timer runs out.
Cant get this to work, here is the code i am using, EC45 gets launched when a user selects the menu option...

                EC45 ec4 = new EC45();
                ec4.Show();
                ec4.PlayMedia(@"C:\\music.mp3");
                ec4.Owner = this;

There is a timer in the program and when it counts down to zero I am trying to close EC45 form and its not working?

Sorry, stupid question.

You have a windows form. Where is the code for the timer located, in the owner form, or the EC45 form? What is the code that starts the timer, and what is the code that executes to kill the form when the timer is at 0?

Andy.

The code for the timer is in the main form1.... below is the code that i am trying to use when the timer hits 0.... the timer works fine I just cant get it to close from EC45.

I tried adding this code to the timer thinking it would make the form EC45 close but it does not.

EC45 AX45 = new EC45();
AX45.Close();



        void myTimer_Tick(object sender, EventArgs e)
        {
            TimeSpan ts = targetTime.Subtract(DateTime.Now);
            if (ts.TotalMilliseconds > 0)
            {
                toolStripStatusLabel2.Text = ts.Minutes.ToString("00") + ":" + ts.Seconds.ToString("00");
                progressBar1.Value = (int)(progressBar1.Maximum - ts.TotalSeconds);
            }
            else
            {
                System.Windows.Forms.Timer myTimer = (System.Windows.Forms.Timer)sender;
                myTimer.Stop();
                progressBar1.Value = progressBar1.Maximum;
                shutDown();
                toolStripStatusLabel1.ForeColor = Color.Red;
                toolStripStatusLabel1.Text = "Cycle Completed....";
                this.fluidEffect1.ImageBitmap = (System.Drawing.Bitmap)System.Drawing.Image.FromFile("C:\\Cycle Completed.jpg");
                fluidEffect1.RenderDrop(75, 75, 250);
                timer3.Enabled = false;
               
             }
        }

I'm guessing that shutDown is the method that you are hoping will close the ec45 form?

I suggest that you store the reference to the EC45 form as a class-level field for the main form, and then use that to get the form reference to close when you call Shutdown. This will only fall apart if you can have multiple forms open, at which point we can put another method in place instead.

public class form1
{

EC45 ec4;

public void OpenForm()
{
   ec4 = new EC45();
   ec4.Show();
   ec4.PlayMedia(@"C:\\music.mp3");
   ec4.Owner = this;
}

public void Shutdown()
{
    ec4.Close();
}

... all your other code ...
}

Are you shutting them all down at the same time, or do they all get shut down at different times?

Did you try to close the form in the  EC45 ? Try to play with easy form without any playable media.

I have put together a simple form, called Form 1. I have then set its IsMdiContainer property to true, and created a menu item to display an EC45 form. I have dropped a timer onto the designer surface for the form and put the following code in its code file (I am using .NET 2.0). After clicking the menu item to create another EC45 form and show it, one second later that form is closed with the timer. Can you get this to work in a test project on your machine? Also, can you post the full code that you use to create and display your four forms, we should check that targetTime is being set properly (I assume it is if you can see your progress bar counting down), and the full code for your shutDown method.
