Events Do not Fire after a few hours of application being opened.
posted

I have a winforms application, and there is a lot of schronization (events firing) between open forms.  I have to update calculations on one form based on a change in another form.  

The approach works great, except for some reason after a few hours, the events just do not fire.  If I close and reopen the application everything is fine.  Any ideas?

 

Some sample code

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using MarketForecastBLL;

using System.Windows.Forms;

using System.Data;

 

using Infragistics.Win.UltraWinGrid;

    Hi,

    For a situation such as this, I would like to suggest running your application through a profiler software application. It can indicate memory usage performance bottlenecks, and other metrics that can point you to an area of the application that may be responsible. Something like this may not be 100% apparent from reviewing the code, especially if the condition deteriorates after several hours of use.
