update text form from another class

Question

Hello,

I am new to c# and have come accross a problem that I just can't get to work right.

Basically I have a form with a text box I want to use a log of events.  I click on a button on the form to run certain tasks, basically this calls a static function in another class.  Work is done in that function, but this also calls a void (sub) in the same class.  I want to upate the text box on the form with info that is being processed in my void.  So, I want it to update the text box live, not all after the fact.

Here is a basic example of what I am doing...

Here Is My Form...

namespace ResponseTester

{

public partial class frmMain : Form

{

public frmMain()

{

InitializeComponent();

}

private void button1_Click(object sender, EventArgs e)

{

string ok = clsDAL.DoSomething();

}

{

}

}

}

Here Is My Other Class..

namespace ResponseTester

{

class clsDAL

{

public static string DoSomething()

{

//do some work

UpdateForm();

return "OK";

}

public static void UpdateForm()

{

string[] files = Directory.GetFiles(@"C:\");

foreach (string i in files)

{

//I want to print each file to the text log on the main page

}

}

}

}

 

I played with delegates and other threads for a while and just couldn't get this to work correctly.  Thanks in advace to any help anyone can give me.

thanks,

Chad
