C# - Updating Panel on UI from different DLL's
<p>I have a GUI that has behind it an interface that allows those dll's meeting it's contract to run through this GUI.  All the work and calculation is done within each dll.</p>

<p>I want to display an update as each record (within the dll) is processed, this update has to be on the GUI.</p>

<p>Is there a simple way of passing this information from the dll, as effectively they don't know what controls are on the GUI.</p>

<p>Thanks.</p>
