[Resolved] Application not using switch for returned string from server

Alright, I have a program communicating with my server to login. The server sends back a success or failure code. The application gets the code, but doesn't use the switch/case I have set up in order to proceed.

Code:

---

string returnString = WebConnection.SendPostData("http://site.com/login.php", "username=" + strUsername + "&password=" + strPassword);
            //MessageBox.Show(returnString);
            switch (returnString)
            {
                case "1":
                    {
                        //Login success
                        MessageBox.Show("Login successful.");
                        //Insert Login code here
                        break;
                    }
                case "2":
                    {
                        //Login failure
                        MessageBox.Show("Login failed.");
                        Application.Exit();
                        break;
                    }
            }

---

If I enable the messagebox to display returnString, it properly shows me either 1 or 2, which it gets from the server. However, from there it doesn't display either of the messageboxes which show success or failure or execute the code it should be using. If I set one of the cases to default, it takes that regardless of the server's response. Is there something I'm missing with the way I'm using case to compare a string?

Are you absolutely positive that the returned string is just single character? There are no spaces or new lines hiding in there?

Yep.

PHP Code:

---

if($row['password'] == $password && $row['approved'] == 1)
        {
            echo "1";
        }
        else if($row['password'] != $password && $row['approved'] == 1)
        {
            echo "2";
        }

That wouldn't assure me; particularly since there is nothing wrong with your switch. Notice that if you pass it a correct string, it works just fine.

c# Code:

string returnString = "1";
 
switch (returnString)
{
    case "1":
        {
            //Login success
            MessageBox.Show("Login successful.");
            //Insert Login code here
            break;
        }
    case "2":
        {
            //Login failure
            MessageBox.Show("Login failed.");
            Application.Exit();
            break;
        }
}

Actually step through your code and see the value of returnString. It's not what you think it is.

After further messing with it, I see it is indeed returning the value with a line break at the end. I'll throw a substring in there to get rid of it. Thanks for the help.

You bet.

I don't know anything about PHP, but if you are going to use the return value like this why not just return a boolean or integer instead of messing around with a string?

Also, if you're done with this question, then you can mark the thread as Resolved.

Good luck.
