表格关闭事件 [英] Form Close Event

问题描述

亲爱的所有人；
我的应用程序变得很奇怪...
在创建表格边框样式=无之前，我创建了自己的关闭按钮，该按钮将关闭当前窗口并打开并将值传递给其他表格.并正在完美地工作..例如，如果我有form1，我想将其关闭并打开form2，完成后，我想在关闭form2之后再次打开form1 ...

我的代码是这样的:

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();
    }

然后我打开form2，依此类推...


之后，我使formborderstyle = sizable，然后我想在不使用我自己的按钮的情况下捕获表单关闭事件. 在初始化函数中，我添加了以下行:

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 :

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

然后我插入函数:

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();
    }

所以现在form2成功关闭了，但是当我在完成过程后尝试关闭form1时，我单击关闭按钮将其隐藏，然后将其隐藏并显示...因此它没有关闭...

如何终止该过程，我想关闭该软件...

帮助...
问候..

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..

推荐答案

您正在执行FormClosing事件中的this.Close().考虑到表单已经在尝试关闭，这很奇怪.

替换为:

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

Replace this:

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

有了这个

With this

e.Cancel = false;

祝你好运！

Good luck!

删除

Hi ,

Remove

this.

Close();
        this.Dispose();

形成您的代码.在执行此行格式时，将发生关闭事件.

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