设计登录表单中存在问题? [英] problem in design login form ?

问题描述

我设计了一个登录表单，但是当用户键入密码并按Enter键时，他就可以进入下一个表单，
此代码无效.

我检查了有效或无效的通行证，但我的问题是按Enter键进入下一页.

表单键Preview = true;

我在文本框keyprees事件上编写此代码.

代码是:

I designed a login form, however when the user types the password and presses enter, so he can go to next form,
this code don''t work.

I checked the valid or invalid pass,but my problem is going to next page with press enter.

form key preview=true;

i write this code on the textbox keyprees event.

code is:

if (e.KeyChar.ToString() == Keys.Enter.ToString())
{

Form3 gh = new Form3();
();gh.Show
}

推荐答案

您可以通过在textbox
的KeyUp事件中使用给定代码轻松完成此操作

you can easily done it by Using given code in KeyUp event of textbox

if (e.KeyValue.ToString() == "13")
           {
               Form3 gh = new Form2();
               gh.Show();
           }

我们可以使用textbox
的KeyDown事件 而且我们也可以重用button的click事件中编写的代码

we can use KeyDown event of textbox
and we can reuse the code written in the click event of button also

private void button1_Click(object sender, EventArgs e)
        {
            Form3 gh = new Form3();
            gh.Show();
        }

        private void textBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
                button1_Click(sender, e);
            }
        }
