Two self-written functions Alert () and checkInfo () are called in the button function.
These two functions are used to confirm whether the edit box is empty and whether the password is consistent with the password value.
Void Alert (string message)
{
MessageBox. Show (null, message, "letter? Information delivery? ? ",
MessageBoxButtons. OK, MessageBoxIcon. Information );
}
Bool CheckInfo ()
{
If (this. textBox1.Text. Trim () = "")
{
Alert ("use? User § name? No? ? Whole? ");
Return false;

}
If (this. textBox2.Text. Trim () = "")
{
Alert ("password? No? ? Whole? ");
Return false;

}
If (this. textBox3.Text. Trim () = "")
{
Alert ("OK? Recognize? Password? No? ? Whole? ");
Return false;
 
}
If (this. textBox2.Text. Trim ()! = This. textBox3.Text. Trim ())
{
Alert ("password? And where is it true? Recognize? Password? No? I? To? ");
Return false;
}
Return true;
