动态登录基于accdb数据库的登录表单? [英] dynamic login based on accdb database for login form?

问题描述

按钮上有此代码，用于登录和打开主表单

KorisnikLozinkaString是基于数据集构建的sql，在该数据库中可以正常运行. 数据源是具有用户名和密码的accdb数据库


Korisnik是用户名
Lozinka是密码

I have this code on button to login and open main form

KorisnikLozinkaString is sql built on dataset and it works fine there.
datasource is accdb database which has usernames and passwords


Korisnik is username
Lozinka is password

private void button1_Click(object sender, EventArgs e)

dynamic login = this.usersTableAdapter2.KorisnikLozinkaString(textBox1.Text, textBox2.Text);

{
if (login == null)
MessageBox.Show("Wrong Entry");
}

推荐答案

很难不知道KorisnikLozinkaString 方法的作用就知道自己在做什么.

It''s hard to know what you are doing without seeing what the KorisnikLozinkaString method does.

我找到了一个简单的解决方案，就在我眼前:

private void button1_Click(对象发送者，EventArgs e)
{
动态登录= this.usersTableAdapter2.KorisnikLozinkaString(textBox1.Text，textBox2.Text);
如果(登录== null)
{
MessageBox.Show(错误的条目");
}
其他
{
MessageBox.Show(成功登录);
mainForm main = new MainForm();
main.Show();
this.Hide();
}

I found a solution, easy one, right in front of my eyes:

private void button1_Click(object sender, EventArgs e)
{
dynamic login = this.usersTableAdapter2.KorisnikLozinkaString(textBox1.Text, textBox2.Text);
if (login == null)
{
MessageBox.Show("Wrong entry");
}
else
{
MessageBox.Show(Succesfull login");
mainForm main = new MainForm();
main.Show();
this.Hide();
}
