Is there a way to trace exceptions and messages captured with the
Enterprise Library to a custom destination like a text box or any
other control? If not can anyone think of a way to "hack" something
like this?
This works. I haven't tested whether the threadsafe part works, but
it's a start. Create a new windows forms application, and paste this
into the main form:
using System;
using System.Drawing;

using System.Componen tModel;
using System.Windows. Forms;
using System.Data;
using System.Diagnost ics;
namespace WindowsApplicat ion11

public delegate void UpdateTextDeleg ate(string pString);
public class Form1 : System.Windows. Forms.Form
{
private System.Windows. Forms.TextBox textBox1;
private System.Windows. Forms.Button button1;
private TextBoxWriter _sw;
private System.Componen tModel.Containe r components = null;
public Form1()
{
InitializeCompo nent();
}
protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Disp ose();
}
}
base.Dispose( disposing );
}
