[TUT] C# How to add a Basic Password to Programs

Well in this tutorial I will teach you how to use an "if statement" to make a very very basic password for your programs.

To start open up your Visual studio and Click Create New Project > Windows form application (Name it what ever you want)


Go to your toolbox and add a button, and a textbox to your form.


Double click on your button and it should open up and look like this.


Now add this code...

Code:

if (textBox1.Text == ("Jaghax"))
{
 MessageBox.Show("Correct!");
}

This is simply telling your program that if the word "Jaghax" is entered into your textbox , then it should show you the Messagebox.

So far this is what you should have and what it should look like.



Push the start button at the top, or go to Debug > Start debugging


Something like this should popup depending on where you put your buttons and if you named them.

Notice, if you put anything else into the textbox it does nothing. That's cause we haven't told it what to do if something else is put there.

Now we need to tell our program what to do if some one gets the password wrong.

Now we need to tell our program to to do if something else is put in the textbox
Add this right below the last "}" in the "if statement"

Code:

else
{
 Application.Exit();
}

This is telling your program to close itself if anything other word is in the textbox other then your set password

It should now look like this


Now open your project again and type in a different word, other then "Jaghax". If you did it right it should instantly close.

This is the end of my tutorial, thank you for reading and if you have any questions or advice please feel free to post it. (I made this myself and I posted it on a different site but felt that it should be released here as well)​

 

Nice tutorial, I'm sure people will find it useful as I have. =)

 

Thanks

I have been gone for awhile. I will write some more tuts in C# if you like.

 

No encryption? No obfuscation?

Easy way to crack this. Open it up in a debugger, search for all referrenced text strings - and there you go

 

Yeah but its supposed to be Basic. Its meant more for learning on how to use basic text boxes. Not meant to be used to hide your bank statements

Its also more of an If statement guide then anything.

 

If you're going to use something that basic, you should AT LEAST store the password as an md5 hash....

 

Nice. not super secure but it's useful ^^.

EDIT: How would I make it if the password is correct, it opens another form file?

 

use form.show() or form.showDialog()

 

Thank you :idea: .

 

Thanks for the tips...../ it helps me lot.....
