Anyone got Delphi Prism?
Anyone currently using or studying Prism? If so, post here. I'd like to know if you're studying it or using it on a real project. Also, did you use Delphi, Delphi for .Net, Oxygene, or Lazarous? We have a few existing Delphi clients we are migrating from Delphi to Delphi Prism this next quarter but I've got Delphi Prism and I'm primarily studying it right now.  I'm filling in the Prisdm data for my Prism Cross Reference Language Guides.

Fix For .NET Framework 1.1 Service Pack 1 Delphi 8
I just posted a Delphi 8 fix for the error "Required package Borland$ not found" caused by the .Net Framework service pack 1 update to our knowledge base at the following link:, , Prestwood KB - D8 Fix Link - http://www.prestwood.com/aspsuite/kb/document_view.asp?qid=100270, , This fix worked for me and all of our Delphi 8 developers here at Prestwood. It is a compilation of information from various sources already on the Internet.

1. Delphi Prism Member Events (event)

Like all .Net languages, Prism events are a separate type of class member. You define a member event by using the event keyword. Events depend on Delegates to define the signature (the type) of the event they represent and they maintain a list of multiple subscribers - unlike in Delphi for Win32, where each event can only have one handler

2. Delphi Prism Event Handler

The Delphi Prism

Most notable for Delphi developers is the fact that Prism does not offer initialization nor finalization sections.

3. Delphi Prism Empty String Check (length)

In Prism, a string can be nil (unassigned), assigned an empty string (""), or assigned a value.  Therefore, to check if a string is empty, you have to check against both nil and (""). Alternatively, you can check the length of the string or use String.IsNullOrEmpty.
