I have had nice discussion about a new Crystal Reports based web-site today. And everything seems to be fine… Except users want to see a proper default name for the exported files… Environment: Crystal Reports 2008 engine IIS 7 ASP.Net 3.0 page with CrystalReportViewer (CRV) being used to show report Read more…
With introduction of garbage collection (System.GC name space) in .Net, life of the Windows programmer become easy – no need to worry about releasing objects, code become simpler, etc. In “old” time one would need to use Interfaces to achieve similar functionality and it does have some advantage even over GC – Read more…
As a long time Delphi and C# programmer one become used to some features of the language and may not go deep into “philosophical” thinking about such features. This often happen with Asserts… What is Assert or Assertion? By its definition Assert: state categorically affirm: to declare or affirm solemnly Read more…
I was always for a “built-in” support of features in modern development environment. Even if it comes in basic form, we, as programmers, should have ability to do “basic” stuff without 3rd party involvement. There are plenty of 3rd party solutions on the market which would help you include some kind Read more…
I am starting a new set of posts presenting small code snippets in C# you could use when working with Crystal Reports in Visual Studio. And the first one is “GetReportParamsAsText“. Very simple but very handy function which allows to include report parameters values in your ASP.Net page without actually Read more…
I was asked today to help with code which would populate the TreeView control from database table in ASP.Net page. Since it is not a first time around and appear to be very common situation with dynamic pages, I thought it may be useful to write about it once and Read more…
Delphi, methods and default values.
Being somewhat unique in methods declaration for the classes, Delphi requires you to have proper method parameters declaration, but:
Convenient. Nice. Easy.
Again, it is convenient since it does not force you to propagate your changes between two if you are to change your default values.
Is default value good or evil?
Well, Microsoft saying it is specific to an implementation of the language (C#) and suggests to use overloads instead. Yes, it can be done, but defaults were introduced for a reason. And, in fact, some compilers, even Delphi, would be confused with overloaded declaration if there is a slight chance of mixing two.
