Dear Daniel,

I tried to mimic yr code but I cant get it workin..

I have a MainForm with a button btnSettings to get a parameter, Nb from the form called SelectForm and btnStartThread to start the longProcess. Now I have the Nb value in MainForm, how do I pass into a class (which is found in another file not in MainForm) Nb

**************************************************************
In the MainForm

public void btnSettings_Click(object sender, System.EventArgs e)
{ SelectForm oSelectForm = new SelectForm();
   oSelectForm.MyParentForm = this;
   if (oSelectForm.ShowDialog() == DialogResult.OK)
   {    if (oSelectForm.comboChannel.SelectedIndex == -1)
         Nb = -1;
         else Nb = Convert.ToInt32(oSelectForm.comboChannel.SelectedItem);
    }

private void btnStartThread_Click(object sender, System.EventArgs e)
{ LongProcess longProcess;
    longProcess.Run();}

**************************************************************
In another separate class file LongProcess

public unsafe class LongProcess
{static long Tmp = 10; // if user did not choose a value for Tmp, default 10 will be used
....
public void Run(){a while loop running here and will be using Nb value}
}
**************************************************************
I hope I have described my problem to you clearly..

Many Thanks.

Class Form1 : Form
{
    void button1_Click(...)
    {
        MyClass o = new MyClass();
        o.String1 = "Hello";
        o.String2 = "World";
        o.SomeMethod();

        /* or */
        MyClass p = new MyClass("Hello", "World");
        p.SomeMethod();
    }
}

Class MyClass
{
    public MyClass() { }

    public MyClass(string s1, string s2)
    {
        _string1 = s1;
        _string2 = s2;
    }

    private string _string1;
    public string String1
    {
        get { return _string1; }
        set { _string1 = value; }
    }

    private string _string2;
    public string String2
    {
        get { return _string2; }
        set { _string2 = value; }
    }

    public void SomeMethod()
    {
        Console.WriteLine("{0} {1}", _string1, _string2);
    }

}

You are very close:

private void btnStartThread_Click(object sender, System.EventArgs e)
{ LongProcess longProcess;
longProcess.Run(Nb);} <---- pass Nb to the Run function

public void Run(int Nb){a while loop running here and will be using Nb value}
}

Does that work
