• Visual C# Converting images to matrix form

  Hi! I am currently doing a project on Locality-Sensitive Hashing. One query I have is whether is it possible to use C# to convert an image to a unique matrix of high dimensions. Any help would be greatly appreciated. You can certainly use this declaration: int[ ] image = { x0, x1, x2, … }; but I think this could get a little tedious. A little more detail in your question would provoke a more accurate response. ...Show All

• Visual Studio A problem about named pipe

  Hi: I have a strange problem about named pipe in Windows XP. I am using named pipe to communicate between two processes. One as a named pipe server, the other one as a named pipe client. The client is indeed a DLL running within some other processes. The function of this DLL is to hook some WIN32 API calls and transfer the parameters to the named pipe server. 99% of time, these will work fine. But at the other 1%, there is a problem for the client to read from the pipe. The error message is ERROR_NOACCESS 998 Invalid access to memory location. I don't know why this happen. And in fact, before the client read from pipe, it will first write to the pipe. And the write is OK. But after a successful write, the read is failed. Does any one hav ...Show All

• Visual C# How to Create a URL syntax checker in C#

  I would like to create a URL syntax checker so that can verify a cerrtain URL not a phish site. But I am also aware that some URL have valid syntax but is still a phish site.

One of the tools is to check for URL syntax error. i have searched for such but has given me no good results that can be of any help to my project. I was hoping that some of the bright minds here could help me or enlighten me in my search. Thanks. I have read about an article about it. They use d ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Memory Leak?

  Heya, I've been working on this 2d game for about a month and a half. A space shooter with a ton of animations. But thats not the problem the problem is recently as the amount of Images has increased I've noticed that the memory usage never stops going up as the game progresses. I know there is some kind of flaw or redundancy in the way i store textures now since the release of beta2 and the content manager. However What would cause memory to keep adding up until the game begins to stutter The structure for storing textures was done before the content manager so it is just a Dictionary class that loads and gets textures loaded via the content manager. The UnloadGraphicsContent method in the game unloads the content mana ...Show All

• Internet Explorer Development IE7 session variable bug ?

  Hi I developed a site about 6 months ago, written in Cold Fusion MX 7. A simple log-in page creates a session struct() variable upon successful log-in and then re-directs the member to their login home page area. On the login home page area, a simple script runs to see if a session variable exists, and if it dosnt, redirects them back to the login page. This is so that people cant access their login home page directly, without logging in. The site works fine in Mac OSX, all browsers and on PC, all browsers, except for IE 7. Does IE 7 have a session bug Appears so. Anyone else experienced session problems of this kind Thanks in advance Jason Hi Jason, I develop websites with PHP an ...Show All

• SQL Server guest in sql2005 from restore database sql2000

  Hi all. I have restored a test database from SQL2000 into SQL2005 and then, since for the SQL2005 database guest is not a database user, when trying to modify its properties, I am getting the error messages : You must specify the logon username. (SqlManagerUI). Thanks for youu help Change the server principal which is mapped to the guest user to reestablish the link between the database principal and the server principal.

• Visual C# Decimal Problem

  Hey I'm currently creating a shopping cart, and i'm having a problem with the data transfered to the SQL Database.

I know that 'linetotal' = "105.26", because i'm using the breakpoint in the debug mode, but when i send this total to the database it automatically rounds up to "105.00". Anyone have any ideas Thanks Rich ok the store procedure im using is: ALTER PROCEDURE dbo.UpdateCartItems (@CartUID int ,@ProductID int ,@Quanty int ,@Linetotal de ...Show All
