• Jop jopper C# no header files. All code is written inline - why?

  Hi, Can someone explain "C# code does not require header files. All code is written inline" what is the advantage in going for inline how does it affect dynamic linking why dont we have header files as in C++ Thanks, Benin. How do you mean C# doesn't do any linking, there are no lib files. It just generates MSIL files, the linking occurs long after the source code is gone, when you have assembly references and the final exe goes looking for them to call into. I think the question should be turned on its head. Why does C/C++ have header files You'll see that header files are an answer to a problem that no longer exists - faster hardware and more memory means that a compiler can directly access all ...Show All

• Gary Pronych How to Iterate through List or IList

  i can add the values to the IList or List, if I need to get these values in the way they went it...Say I added 5 addresses to the list and I want them one by one... I can use foreach and get all, but I need a way to only get one at a time or two at the max as I need to update some textboxes... are you referring to the generic type if so then.... theList [ Index ]; index being the position you wish to obtain the value from in the list collection. Say if I do something like this : foreach ( Phone phone in ContactPhoneNumbers) now phone has everything I need....How can I get index from there........ or How I can do this if(theList[0]) // This gives me an exception.... ...Show All

  Hi! How can i add existing resource file to a C# project in VS2005 without breaking the connection Lets say that i have a resource file, "MyStrings.resx", with one single string resource MY_STRING = "Hello!".

• Andre.Ziegler How to get mem-size of a structure?

  Is there a way to get the memory size used by a structure (say a 2-dimensional array of type String) I need to compare implementations mem-wise, but I can't find what I need to know. I hope this isn't a too dumb question :x You won't necessarily be able to extrapolate from the memory size of individual types to the run-time memory usage of an application, if that's what you're getting at. The run-time memory characteristics will depend heavily on how you use the memory and when the garbage collection decides to run. Can you be more specific about the comparison you're trying to do -Tom Meschter Software Dev, Visual C# IDE I am representing a polygonal 2D structure (mapped onto a grid) into m ...Show All

• silkkeng A question of OO structure...

  Hello All, I'll do my best to explain what I'm trying to accomplish and look forward to any and all suggestions you have for the "proper" way to do this (realizing there is no 100% correct way, but some methods are more optimal than others). I apologize in advance for my n00bness. For this example, I'll use football (american) players. I want my Player class to have a List<Stat> collection of my Stat class. Each Stat, which is an indicator of how well a player plays a particular position, should have a base value but be able to return a "true" value which is a calculation of the base value plus a percentage of one or more other stats. For example: a Player's Halfback stat might be base value plus 50% of the Fullba ...Show All
