VS 2012 C++ Windows Form Applications help

I'm trying to debug my little program here, but it's failing to do so. It says it has build errors.
I don't know what to fix in my code. It's just a simple if statement, and I don't know why this error keeps popping up, even though I've read the error myself. When I delete this if statement, all goes well.

Screenshot of my code:

Screenshot of the error:

Why not use IsNullOrEmpty ?

Code:

if(String::IsNullOrEmpty(richTextBox1->Text))
{
    MessageBox::Show("Short");
}

And after the messagebox has popped up. It'll still continue with the program so the check is rather useless.

Could you just briefly explain in easy words what IsNullorEmpty means? Or just what Null means?

richTextBox1_TextChanged method is missing, you probably subscribed to the event but deleted the function and it's still there in InitializeComponent or whatever.

You need to remove the line which looks something like this:
richTextBox1->TextChanged += gcnew System::EventHandler(this, &Form1::richTextBox1_TextChanged);

TextLength will save the overhead of obtaining the text buffer and then converting it to a .NET string.

Thanks. That fixed the problem and now it's running fine.
You can close this.
