An EXE is a specially packaged file that contains information on how to start running the code in the file in a Windows process.  A DLL only contains code, not all the housekeeping information.  A program called a linker is used to link OS related housekeeping code into the EXE file to make it executable.

This a SUPER easy in WPF. Read up on Styles and ControlTemplates. There are a lot of WPF articles here on Code Project that cover this topic. This is one of the foundational powers that WPF delivers. You can simply write one Style, place it in application scope and all Tree controls can use it. The possibilities are endless.

My expert opinion is you should not post unformatted code, especially when its XML. I won't read an XML file with > and < instead of the '>' and '<'-symbols, not to talk about syntax highlighting. I cant even copy&paste the code this way. "Obstacles are those frightening things you see when you take your Eyes off your aim" - Henry Ford Articles  Blog

The first is simply not possible, since an interface can only contain signatures of the following members: Methods, Properties, Indexers and Events; and this delegate void MyDelegate(); declares a type that references a method.

Hi Kevin, Finally I have done with it. The problem is not with WCF and [XmlSerializerFormat] attribute is also not required for service contract. The key concept is JAVA client can not get an Array of object of DataContract member. I have tried several ways but Array of Employee class never worked out. I tried it with List and it worked very fine. Thanks for your prompt response and guidance.:-D Jayant D. Kulkarni Brainbench Certified Software Engineer in C#, ASP.NET, .NET Framework and ADO.NET

Adapter.Update calls insert, update, delete in subsequent manner. Hence when I call Adapter.Update(dataTable) it throws primary key constraint failed or unique key constraints failed exception.
