Accessing Form elements from separate class

Joakim Astrom

Hello people.
I am wondering if it is possible to somehow access my richtextbox from a separate class I am using. The project is a Windows Forms Application.

namespace WebCrawer1._1
{
      class SpecificDistributor : Distributor
      {
            public SpecificDistributor() { }
            public override void start()
            {
                     richTextBox1.appendText("from my separate class\n");
            }
      }
}

The SpecificDistributor class inherits the Distributor class. But how can I "link" the SpecificDistributor class to access the elements from my Form directly? In this case I just want to be able to logg information in the richTextBox of my Forms Application from my separate class.
Thanks.

Hello Nainil. Thanks for your reply. I solved it by sending the instance of the Form object to the SpecificDistributor so I can access it from there, and then I made the richTextBox "Modifier" to internal so it can access it directly. Your solution was more specific and perhaps better.
Thanks.

You can create a property of type RichTextBox in the SpecificDistributor class and once you instantiate the SpecificDistributor class in the Windows application, simply set the instance of RichTextBox on the form to the poperty of the SpecificDistributor class. Something like this:

class SpecificDistributor : Distributor
{
      public SpecificDistributor();
      public RichTextBox oRichTextBox { get; set; }
      public override void start()
      {
            oRichTextBox.AppendText("from my seperate class\n");
      }
}

In FormLoad event, do this:
SpecificDistributor oSpecificDistributor = new SpecificDistributor();
oSpecificDistributor.oRichTextBox = this.RichTextBox1;

Hope this helps.
