Question

I have a main form with a textBox1 with string value : asd

namespace Crystal
{
    public partial class MainForm : Form
    {
       //here is a textBox1 with text "asd"
    }
}

I want to change this textBox1 text from this class:

namespace Crystal.Utilities
{
   public class Logging
   {
       //textBox1.Text = "dsa";
   }
}

The problem is, I cant change the value of textBox1 from the Logging class, because it doesnt exists there :/ How to do this?

Don’t need to expose the entire TextBox – Don’t want others to mess with other things than just the text, and I think it’s more readable and simple to just call a method that does that, instead of accessing the TextBox directly.

namespace Crystal
{
    public partial class MainForm : Form
    {
       public void setTextBox1Text(string newText)
       {
        TextBox1.Text=newText
       }
    }
}

namespace Crystal.Utilities
{
public class Logging
{
mainForm.SetTextBox1Text("new text");
}
}
