在登录表单中填写表单 [英] Formclosing in Login form

问题描述

大家好，



我有两种表格的申请：登录和主体。



当我在我的应用程序午餐时，出现我的登录表单，我输入用户名和密码。

问题是当我使用不正确的凭据关闭我的登录表单时，会出现第二个表单。



所以，我用这段代码插入formclosingevent：

Hello everyone,

I have an application with two forms: login and mainform.

When I lunch my app, appears my login form where I put username and password.
The problem is that when I close my login form using incorrect credentials, the second form appears.

So, I insert the "formclosingevent" with this code:

DialogResult warning = MessageBox.Show("Exit?", "Warning", MessageBoxButtons.YesNo, MessageBoxIcon.Warning);

            if (warning == DialogResult.Yes)
            {
                Application.Exit();
            }
            else
            {
                e.Cancel = true;
            }

因此，用户必须写出正确的凭据才能输入我的第二个表格。

但问题是：当我写出正确的凭据时，我的第二个表单出现了，但登录的表单向我询问我之前写的消息（DialogResult warning = MessageBox.Show（Exit？， 警告..）。



如果凭证合适，我该如何隐藏消息？

So the user must to write right credentials to enter in my second form.
But the problem is: when I write right credentials, my second form appears, but the login's form ask to me the message that I wrote before (DialogResult warning = MessageBox.Show("Exit?", "Warning".. ).

How can I do to hide the message when credentials is okay ?

推荐答案

Formclosing是一个在将要卸载表单时调用的事件。您可以将对DialogBox的调用放在一个条件中，该条件检查已按下哪个按钮（带有标志或类似按钮）。

Formclosing is an event that is called any time the form is about to be unloaded. You sould put the call to DialogBox inside a condition that checks which button has been pressed (with a flag or similar).
