:-S

Any help please??


To each of your forms you can add a property that will reference the other form. This will give you access to the other form and all the controls on it through the property.

public property Form RTForm { get; set;}

You can then set this property in the place you construct the forms.

Form myForm = new Form();
Form rtForm = new RTForm();
myForm.RTForm = rtForm();


There are several ways. You could just define a property on the one form which contains the richtextbox, which can be found by your other form.

public static string RTextboxText
{
    get
    {
        return myrichtextbox.Text;
    }
    set
    {
        myrichtextbox.Text = value;
    }
}

Setter can be dropped ofc.

Another way is to use a class between the 2 forms. I think you also use specific actions on the text? You might want to put all your code about that, in that class as well.
