+=  Question: How do I create a dot net overlay options (given example doesnt work) =
+
+Hey,
+
+I am trying to create an overlay options page/panel in C# .net 2.0 (VS2005) for Falcon View 4.1.
+
+I have looked at/used the example given here [wiki:HowToCreateAnOptionOverlay] and it shows up fine in the options window but when I try and call OnModified() with:
+
+'''if (OnModified ! = null) OnModified();'''
+
+OnMidified is always null, indicating to me that no one has registered for my events. I can't find any way to get this to work.
+
+Does anyone have any ideas?
+
+Cheers,
+

+The problem is because of the way the preference control was created.  ActiveX events will not be connected on Windows Form controls when used as ActiveX controls.
+
+Developers using .Net should create a "Control" instead of a "Windows Form" when creating the ActiveX preference control for FalconView.  Simply put, create a single container control which contains all prefrences for your overlay.  
+
+If you are an editor overlay, also create a simple form to show the control in a dialog for the user.  Your overlay will display this form when the user opens preferences from the editor toolbar.
+
+See HowToCreateAnOptionOverlay for a code sample.
