Question

I have a Windows Form application with a button named loginBtn and a label called loginMessageLbl on my form.

Now when I write the following piece of code it gives me an error sayin “The name ‘loginMessageLbl’ does not exist in current context”.

I am not sure how do I change the text value of the label once I click on the button:

namespace WindowsFormsApplication2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
             InitializeComponent();
        }
        private void loginBtn_Click(object sender, EventArgs e)
        {
               loginMessageLbl.text = "Invalid Username or password";
        }
    }
}

Intellisense should tell you if it exists when you typed it out – it would also help you if you’ve got the name slightly wrong or capitalisation is different. Also, you’re trying to set a property called “text” – the property you actually want is “Text” with a capital T.
