• .NET Development COM+ exposing public classes ?? !!

  Hi Guys, Im facing a problem with the COM+ component, will appreciate if u can provide any kind of guidance. My COM+, references a class, lets call it class A. It uses the properties of Class A, and has methods to return / insert / update / delete etc. I have an Admin module(another dotnet solution), which accesses the COM+ component (via referencing the dll). And uses the methods which are in the COM+.   Now the problem is, the admin module also need to use the Class A(which is already referenced by COM+ component), as it has to use the properties and methods of Class A as well. How to achieve this using the present COM+ compo ...Show All

• Windows Forms CollectionEditor CancelChanges() method

  Summary of the problem: The CollectionEditor class, CancelChanges() method doesn't cancel the changes to the underlying collection. In fact, I used Reflector to see what the method does. Here it is: protected virtual void CancelChanges () { } There's no code in that method. ! I created a Collection editor inheriting from CollectionEditor to edit my collection of objects on my UserControl. Say you add objects to the collection using the collection form. Click OK. Everything is good. Now, click in the propery grid on the Items property and modify some properties on the object(s). Click the Cancel button. Now, click on the Items ...Show All
