Create HTML Image Maps Dynamically With .NET: ON: 2007-07-04 13:24:01; I've been working on a financial reporting project lately and came upon the idea of bringing our charts from ChartFX.NET to life. The idea being that we could dynamically review each pixel's color in the chart in order to generate an HTML image map on the fly. This would enable us to apply supporting documentation in the form of links or JavaScript functions to perform some sort of action when the user moves their mouse over the chart or clicks a section of it.; 45 times | category: [NET]

How To Use Refactoring To Handle Multiple Versions of Classes: ON: 2007-07-04 13:22:38; Recently, I had a requirement to put together a website that deals with taking somewhat elaborate financial surveys. While the questions and answers themselves are good candidates for being database driven, there were a large number of nuiances ranging from UI items, business rules, and calculations that just didn't fit into a database driven strategy. With this in mind, my initial strategy was to create version specific classes and reference them in version specific ASP.NET pages. Of course, this accomplished the initial requirement. However, whenever a new version needs to be implemented, I had to copy all of the ASP.NET pages and modify the references to the appropriate version specific class name. Refactoring provides a better alternative and here's how:; 4 times | category: [NET]

Hierarchical Relationships Without DataRelation Object in ADO.NET: ON: 2007-07-03 15:19:14; At my place of employment, I work a great deal with somewhat complex hierarchical data as part of our measurement and analysis software. Thus, recursion and I have become rather close friends over the last few years. While rewriting an old website, I needed to turn a set of four relational tables into a hierarchical data structure. The top level table held self-referencing relationships as well as child relationships to table 2. Tables 3 and 4 were your basic "run of the mill" child tables up through table2.; 47 times | category: [NET]

Using ASP.NET Code-Behind Without Visual Studio.NET: ON: 2007-07-03 14:44:00; The author writes "One of the things that keeps coming up as a benefit of switching to ASP.NET is the ability to use code-behind to separate display code from application logic.

It is dangerous to store passwords anywhere in plain text!! SHA1 gives a quick and easy way to encode a password into a non-human readable form. This means it is safer to store in a database, and should the database be viewed by anyone who shouldn't know the passwords, it will be much more difficult for them to work out what a user's password is.; 16 times | category: [NET]
