Dear All ;
My application is going strange ...
before I was making the form border style = none then I create my own close button which will close the curent window and open and pass values to other form. and was working prefectly.. for example if I have form1 and I want to close it and open form2 and after finishing I want to open again form1 after closing form2...

My code was like that :

openform2(object sender, EventArgs e)
    {
        functions fn = new functions();
        form2 ts = new form2();
        ts.Text = " Welcome Mr." + fn.GetuserNameFromFile();
        this.Hide();

        ts.ShowDialog();
        this.Close();
    }
then I opens form2 and so on...


after that I make the formborderstyle = sizable then I want to catch the form close event without using my own button .. what I have done in the form2 is the following :
at the intialize function I have added this line :

MIDL
this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.MainForm_FormClosing);


and then I carete the function :

private void MainForm_FormClosing(object sender, FormClosingEventArgs e)
    {
        functions fn = new functions();
        form1 f1 = new form1();
        f1.Text = " Welcome Mr." + fn.GetuserNameFromFile();
      // that means to close the current form2 and show form1 again 
        this.Hide();
        f1.ShowDialog();
        
        this.Close();
        this.Dispose();
    }



so what happens now the form2 closed succesfully , but when I try to close the form1 after finishing my proccess so I click on close button it is hiding it and then showing it hidding and showing ... so it is not closing ...

how to kill the proccess I want to close the software...

help...
regards..

You are doing this.Close() in the FormClosing event. That is pretty strange considering that the form is already trying to close.

Replace this:
C#
this.Close();
this.Dispose();


With this
C#
e.Cancel = false;


Good luck!

If I will put e.canecl is that means that I close the current event which is trying to close the window?? No just I was thinking that when I call the formclosing function it will not close the window it will just apply the code inside the function, so for that I have add this.close, but now I commented all the code and make it emptye function and it closes the window .. so by conclusion it is closing the windows and when we are adding : += new System.Windows.Forms.FormClosingEventHandler(this.MainForm_FormClosing);
that means we are adding to main event a new functionality..
that is great.. thank all for you comment
Hi ,

Remove

this.
MIDL
Close();
        this.Dispose();


Form your code. On execution of this line form closing event occur.
