• Inkyskin_UK Advantages of OOP ?

  Hello, Im a fun of OOP designs. I design my bussiness classes when I start a new project. Then maybe I will write mapper classes for bussiness classes to map DB tables or using an O/RM tool or an ODBMS . Think that this project is big one and it has long deadline. You will develop it 2 or 3 years. Requirements will be changed. To develop this project with OOP designs and n-Tier application design is good idea. But I am asking myself ...Show All

• VASUSIVA a Common Form that hosts data/connections for other forms

  Hello, We are former Delphi developpers and are having a 'problem' to setup a kind of a datamodule. This could be an insible form that has a connection to a accouting system over dcom. Now we would like to call the procedures on that form from several other forms. We don't want to create a connection on each form (app is mdi). How could we do this, and mostly, how would we reference that 'common' form. Kids Regards ...Show All

• scottsignalscape Databinding vs Multi-tier

  I'm a bit confused - see if you can help me out. It seems like microsoft is really big on the multi-tiered approach to development(presentation, business, data), but now, with visual studio 2005, they're also really pushing the new and improved typed dataset for databinding. Am I wrong, or is it virtually impossible to take full advantage of the new typed dataset and still separate your system into presentation and data layers You create a data ...Show All

• chrisbtoo XP or XPE for POS application

  Hi, Not sure if this is the correct place to post this - apologies if it's not. I'm developing a custom POS application in VB.Net 2.0 for no more than 4 terminals. The touch terminals all have P4 processors with 512 MB RAM and 40 GB HDDs. I'm just wondering if there are any advantages to installing XP embedded (or XPE for POS) instead of XP Professional. Because of the limited number of clients, it would be more expensive to buy t ...Show All

  When the user logs into the system, I need to go grab some information (Full Name, Email, EmployeeID, Etc.) and store it in a global place for the application to get at. I can think of two options off the back. I could create my own custom principal / identity classes and store the information in here, or I could go ahead and create a UserProfile object and make it a singleton and store it there. Which option do you guys think sounds more approp ...Show All
