• Visual Basic .Net certification

  Do you know any web site for .net or SQL server certification practice. I m beginner and I have no idea how they look like. Also if any web site to prepare for them I appreciate your help. (sorry I didn t know where to put my question) TestKing has a hidden 90 day access policy on their software. You buy something for $50 thinking it’s yours and 90 days later you find out its not and for another $25 you can access it again. The only place you can find this information is in their FAQ section, which of course I didn’t look at until I could not open the software. I wrote the TestKing sales staff and asked them for my money back be ...Show All

  use which binding which channel Hi Leo, WCF includes a feature called "PeerChannel" for writing just these sorts of peer-to-peer applications. We have a great sample that shows how to write a chat application using PeerChannel: http://windowssdk.msdn.microsoft.com/library/en-us/WCF_samples/html/813dc74f-bfcf-43a8-96ce-4d72c083e5f3.asp .

  I have a MS C/C++ compiler version 12 for 80X86 on a PC running Windows 2000.

• Visual Basic Random Numbers

     I'm realy green when it comes to programming but I like to think I am learning quickly. However, I cant figure out how to generate a number of random numbers baised on the vailu of a numeric slider. So for example I am generating a number between 1-12 where each point of value for the slider would generate an indiigual number that can all be added to a final total. I would also like to be able to back the slider down to a previous number and have the same total I had last time I was at position x. This is what i have so far: If levelHP = 1 Then hpcalcbarb = ConBonus + 12 LblHpTotal.Text = hpcalcbarb Else ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. storing of directx sample

  How does directx stores it's samples I have a 22KHz WAV file , with 8 bit's per sample . I load the wav into a buffer. I want to create a pointer to go over a locked portion of the buffer , sample by sample . What cast should the pointer be is it double byte  or what   A general theme in DirectX is that it will give you a pointer to the raw block of binary data - it doesn't tend to format it nicely so that your language/program can easily walk through it. As such, if you've got 8 bits per sample, you'll want a pointer to an 8bit quantity. You don't mention your language/IDE, but if you're us ...Show All

  how can we develop for mobile devices like pocketpc and palm os using free express IDEs. what are the sdks to download and how to emulate a mobile device supporting .net framework CF 2 without VS 2005. please answer.... You can not. You need 2005 Standard or above to do that. Or, you can use free SDK which already includes NETCF SDK (command line only). Also, you can't develop for Palm OS using Microsoft products (not without some 3rd party add-ons anyway). You can develop for Windows Mobile based devices from Palm, though. ...Show All

• Visual C# A common application for recursion

  Hi, A common application for recursion is the problem of generating all possible permutations of a set of symbols. For the se consisting of symbols A,B and C there exists six permutations - namely, ABC, ACB, BAC, BCA, CBA and CAB. The set of permutations of N symbols is generated by taking each symbol in turn and prefixing it to all the permutations which result from the remaining N-1 symbols. It is therefore, possible to specify the permutations of a set of symbols in terms of permutations of a small set of symbols. How to write a recursive function program for generating all possible permutations of a set of symbols using C#. Thi ...Show All

  Hi I have accidentally deleted some sources in my project and want to know if there is a way by which I can extract my code from the dll Shantanu Yes, you can use Reflector . It's a good tool that allows you to recover your code, change it into a different language, peep into the framework (quite instructive!) and in other people's code (except you should not). It will also show you why it is a *must* to seriously obfuscate your code before releasing it (but before you do, have your sources backed up at least twice ;) ). HTH --mc ...Show All
