Hi all, I'm trying to get my login window to only continue a string of code if the user enters 1 of the correct product keys.

The code that I need to execute when 1 of the correct product keys are entered:
MainWindow win2 = new MainWindow();
win2.Show();
this.Close();

If there's a way of showing me how I should set out my data table on my server as well, that would be great.
----------------------------------
Here's the code that currently activates when ANYTHING is in the password box:

private void TextBox_TextChanged(object sender, TextChangedEventArgs e)
        {
            MainWindow win2 = new MainWindow();
            win2.Show();
            this.Close();
        }

----------------------------------

What I have tried:

I've looked all over Google, but I can't seem to find something that works with password boxes. (I'm quite new to WPF c#)

You SQL question is hard to help you with without knowing your SQL server table structure, obviously. Do include for specifics.

A PasswordBox type control supports a property Password server side, however it cannot be bound to for security reasons. See details: [^]

Which me wonder why you're acting on the text changed event of a textbox?
Clearly you don't want to act on every change but not until for instance some button is pressed.

<StackPanel Margin="10">
       <Label>Text:</Label>
       <TextBox />
       <Label>Password:</Label>
       <PasswordBox id="MyPasswordBox" />
   </StackPanel>


and then on the codebehind you can simply access it with

C#
string password = MyPasswordBox.Password;


Of it is boxed in an event like object, remember to unbox it first.

C#
var pwBox = (PasswordBox)sender;


But don't try it if you sender is on your button event ;)

Thanks a ton for your help! I have yet decided not use a database and use the application itself instead. I'll accept this as the correct answer as this does work.
