• Visual Studio 2008 (Pre-release) WPF = 50% C# + 50% XAML?

  for the past 6 weeks ive been working with wpf applications and i still cant quite get my head around what i should and shouldnt be doing with xaml ! i think my point is best explained with the project i'm working on at the minute - a graphs package. from my understanding xaml is essentially the UI, ie how pretty and nice it looks, correct or is it much more than this i'm using polylines to draw each line. now i'm using them in xaml because the binding works lovely :-) however although they are part of the UI in the sense of being visible they are not part of the UI in the sense of how nice it looks (the look and feel) of the application. I feel as though i am spending alot of time 'trying' to create as much as possible of my application ...Show All

• Audio and Video Development A major Bug in Sonic Premastering...IMPORTANT READ

  Just got a grasp on what is happening when I premaster... In Standard Content I take my advanced content and hvdvd_ts folders and burn them but I just realized it is making my hvdvd_ts subdirectories dissapear! I have hvdvd_ts\background\pevob01.map and when I burn through Standard content all that shows up on my disc is the root of the hvdvd_ts folder. So any subdirectories in hvdvd_ts are gone! Major issue. It should burn my project as it is and not be removing folders! I am burning 2 folders ADV_OBJ and HVDVD_TS this is advanced content...the only way to premaster with the sonic tools is to open Standard Content and select premaster, then select advanced folders, then burn...but you should be able to burn an advanced content disc ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Game AI

  Hi, i am currently working on a simple first person shooter game and this is the first time i am at it. I am actually working on the AI part where the enemies must find the correct player and attack, I have seen some shortest path algorithms like A* and it's variants I want to know in which manner or format the MAP must be stored and conveyed to the CPU players so it is efficient.I want to know this because in a complex map there may be a lot of crucial points and terrains.. Didn’t say this before, but when accesing the Map, you cannot of course just plug player’s position into the array indexers. You have to search for the closest point in the map. For example: Player’s position = (0 ...Show All

• SQL Server NoLock vs ReadPast

  I have been experiencing deadlock errors with two stored procs that I am using. SP1 is a read query that gets all unprocessed orders (status = 0) SP2 is an insert query that inserts new orders (Status = 0) uses a transaction. I have a multithreaded application and once in a while the read query (SP1) will try to read a new row that has just been inserted but not committed yet hence the deadlock arises. If i use a hint "With(NoLocks)" this will be a dirty read and still read the uncommitted insert from SP2 - is this correct Where as if I use hint "With(ReadPast)" this will now only read committed rows and hence the deadlock should not arise - it will not read any uncommitted rows - Correct So I think th ...Show All

• Visual C# probem with generics

  Hi, I've written the the code below: static public void Test<T>(T arg) { write(arg); } static public void write( char c) { Console .WriteLine( "char" ); } static public void write( int c) { Console .WriteLine( "int" ); } It should be possible to write like this: Test('c'); or Test(10) and the appropiate write methods should be called. When I try to compile it I get two errors: Error 1 The best overloaded method match for 'tester.Program.write(char)' has some invalid arguments. Error 2 Argument '1': cannot convert from 'T' to 'char'. Is there another way to make the templated method call the appropiate methods. It seems to me that writing some ...Show All

  Hello, can anybody tell me if the repsonse of a webservice created in .Net 1.1 and migrated to .Net 2.0 is exactly the same Are there differences I need to know this, because a lot of different people accessing my service are using different technologies to consume the service HarCore-Parsing and so on.
