Hi,

i've got a main form. It's an MDI Parent. In this parent i'm opening a second form and and i'm using a class.

Looks like this:

C#

public partial class Main : Form
    {
     Serial serialPort = new Serial();
[...].     Util childForm = new Util();
[...].     childForm.Show();

this works fine. I can start the childForm and work with the serialPort in my Main form.

Now i want to use the methodes from my Serial class in the opened childForm. How can i do this without the existing serialPort in the Main form?

Solution 1

You'll need to pass a reference to the Serial class to the child form obviously. :rolleyes:

Create a overloaded constructor and pass it in or create a property and set it.

Try 'c# passing parameters from one form to another' as a search phrase.
