• 13117 Which book to start with??

  Okay... I've got a variety of different books and tools to learn C# with. The problem is the one that is my FAVORITE is using an old rendition of the language (from 2002) and an old IDE. "Microsoft C# Game Programming for the Absolute Beginner" My question is: is it harmful to use OLDER books to learn a language Yes, I have newer books like "Teach yourself Visual C# 2005 in 24hrs" as well as videos from VisualStudio.Net and Prentiss Hall's book, but when it came to raw coding I found the former book more useful and more fun. But, am I gimping myself by not using the newer 2005 books I've come to also notice that the newer books seem to focus a LOT more on working within Windows Apps, which I think is a bit c ...Show All

• Gordon Hempton Add Web Reference

  When I add a Web Reference from Visual Stuido it can take upto 4 minutes to complete (build the proxy). This is for a very simple webservice with only three web methods held on the same machine. Has anybody got any ideas why this should take so long Thanks Dave Yes I do. There are a total of 20 projects in the solution, two of which are web projects. IIS is installed, but this is just a simple Web Project using the built-in server. Do you have both the web service project and the project that consumes the web service in the same solution Just curious, do you have IIS on this box or are you using t ...Show All

• Eric Wisdahl real-time use of Indexers & Properties...

  hai, I need help regarding Indexers & properties, what is the use of properties & indexers, and how it is applied in real-time applications .. thanks.. " if a member of a class is declared as PRIVATE, then it can't be accessed by the code outside the class. But properties break this concept,so no encapsulation or data hiding can be achieved. If properties are defined for the particular class that has private members, we can access the PRIVATE members using properties from outside of the class. Won't this be a *drwaback* " Remember, that Properties are just METHODS that are handled as properties in C#. For example, a get and set Property MyProperty will be compiled to get_MyProperty and set_MyProperty -methods i ...Show All

• redfish How to build a global connection with ODBC?

  I could not create a global connection with ODBC. It needs to identify in a method, not in a class out of a method. In this case while program running, it builds and destroys million connection. In every loop in the called method creating a new connection then doing something then closing it. This condition takes so so much time. I want to optimize this. So at first I should create a global solid connection. Program should do own work with out creating new connection but with using the connection. Finally when finishing the program, connection will be closed. Could you help me Regards... I can write my codes. But I wish explain the condition. At your code, when the program counter come at "foreach" it will d ...Show All

• BuddhaDave project properties file(s) and web references

  A project Im working on was updated by someone else (via source control) and apparently they created some properties files when they added a reference to a web service. However, i think they didnt do anything explicity to do this, but when i updated my code with these changes, I didnt have these properties files and hence my build failed. Why would adding a reference to a web service cause data to be saved in a properties file and how can I avoid it What's the name of the properties file that you were missing Anson ...Show All
