Hi experts,

how to access the main appclication form  controls ?

I don't like it doing it in the way below:
       
class newObject
{  
        private control xy;

        public newObject(MainApplicationForm application)
        {
            this.xy = application.control;
        }
}

Is there another chance to access to the controls ?

If you want to access controls from any place from the program, expose them as properties from main form class. Make public static property with form reference and access controls using it.

class MainAplicationForm
{
    public TextBox TextBox1
    {
           return this.textBox1;
    }
    // ... add property for every control you want to expose

    static MainAplicationForm mainAplicationForm;

    public static MainAplicationForm MainForm
    {
          return mainAplicationForm;
    }

    public MainAplicationForm()
    {
        mainAplicationForm = this;
    }
}

To access textBox1 from any place of the program, assuming that main form is already created and there is only one instance of it:

MainAplicationForm.MainForm.TextBox1.Text = "...";
