• Visual Studio Express Editions Hex Calculations help Please

  I think I have presented myself with a rather difficult challenge. I need to convert a hex value to Radix 24. I'm not sure if this these are the right terms but I think it's converting a Base16 to a Base24. If any one could maybe help me out I would be extremely grateful. I have searched the internet for a long time and was only able to find calculators. I do need this for VBEE that's why I'm asking here <br> Well as far as I know you end up helping me 99% of the time. Thanks. As for changing Dims to Long and CLng I still get "Value was either too large or too small for an Int64." It happens at: N = CLng(Number) 'Convert.ToInt32(HexNumber, 16) This is what I'm trying to convert: 417173139863451964492081697286136322 And this is ...Show All

• Visual Studio 2008 (Pre-release) IList Best Practice

  Hi, I'm creating an operation that returns generic IList implementation (Collection or List). The proxy class generated returns an array of the generic type. I would like to know the best practice of doing this. Can svcutil be tweaked to return the collection or list Or am I stuck with arrays Thanks! That's not what I meant to imply. What I mean is this: You can convert a List<T> into an array of T in one line of code, and you can create a List<T> from an array of T in one line of code, so the "limitation" that XML serialization of service type responses forces conversion into an array isn't really that big of a nuisance. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA - Redistributable License Clarification Please

  Hi all, Hi all, I realise the XNA is only beta form, but I would like to make 100% sure that we would be allowed to distribute the xna dlls ourselves with any game we made. In my case this isn't for a commercial venture, rather there are a couple of development competitions I'm interested in, particularly at gamedev.net and xbox360homebrew.com - that I would like to enter a game based on xna for. For the xbox360homebrew.com competition, the rules are lax and the audience is basically other people messing with the XNA too. The gamedev.net 4E5 competition however is more strict as far as what has to be installed on an end-user machine to get a game working. I expect demanding them to download and install the 100s ...Show All
