I have one dll made by C# winform. I added a new form in that dll with two buttons, 1. OK 2. Cancel.

In this situation the form can return 3 values.
1. Cancelled (Cancel button)
2. Success (From OK button)
3. Failure (From OK button)

I want to give that dll to other developers. They will work in their codes based on the three values mentioned above.

My question is, how to return these three values from the dll?

My dll code pattern is given below:
----------------------------------------------

class <dll name>
{
        function 1
        {
        }
        method 1
         {
         }
        function 2
        {
        }
        method 2
         {
               frmAbc fmAbc=new frmAbc     //this is my form i introduced in that dll
         }
}

class <form name>
{
      private <ok button click event>
      private <cancel button click event>
}

Use the DialogResult member. Then your 3rd-party users can either reference that member directly, or they can use it by means of a call to ShowDialog. For more info: http://msdn.microsoft.com/en-us/library/system.windows.forms.form.dialogresult.aspx
