• Visual C++ Vector Based Game

  I was looking to write a vector based game. Mainly its to learn not to entertain. i want to code it in c++ and was wondering if someone could point me to a few resources; i have had some trouble finding any code examples. MIND magazine has had some game programming articles but I don't know anything about them except that the first article was MIND Column: Fun and Games . You should look for the subsequent articles in that magazine. I am not a game programmer myself but I have bookmarked some sites when I encounter them searching for other things. A good site for game programming I think is GameDev.net . Other possibilities are: Amit’s Game Programming Information Game Creation Resources fl ...Show All

• Visual FoxPro "Select" is different from "browse"?

  I use select and browse with a cursor but I get 2 different result. Code: SELECT refno, ItemID, ItemInvId ,convertquantity from curDetailAlias WHERE ALLTRIM(refno) == b;    ORDER BY ItemID INTO CURSOR curBangDoiTru  Browse last for ItemID = b   Can anybody help me Thanks in advance.   As said in previous messages there are differences in ANSI and EXACT comparison. Now that you tell the problem you are obeserving another difference between select - sql and xbase browse. Select SQL works with records that are committed to disk only (except "with buffering" clause in VFP9). xbase commands on the other hand work with records that are on the disk + buffered.

• .NET Development Request for the permission of type FileIOPermission failed

  I have a ASMX Web Service that references a custom DLL we have created. The DLL has a function to read some settings from a XML file that we deploy along with the web service on the web server. When I run the solution on my local machine using the web server built into VS.Net 2005, everything works great. When I deploy it to our Web Server running IIS, I'm getting an error saying it doesn't have proper permissions to read the file. The entire exception message is below, but it looks like it's saying the assembly that caused the failure (my custom DLL - BusinessModel.DLL) is in the MyComputer zone. Shouldn't this mean that the assembly has unrestricted access to the file system I don't have any security specific stuff in my code (no att ...Show All

• Visual Basic Sorting using a Ibindinglist that supports changenotification

  Hi, I have a custom class that inherits from collectionbase and implements the Ibindinglist that supports sorting as well as Changenotification. I use another part of the application to change the data within the collection. The updates appear on the datagrid without any explicit refresh of the datagrid as it should. But whenever I try to sort a column of data that is constantly changing I get an index out of range error. Any help in resolving this error would be greatly appreciated. thanks, Deva ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Game and GameComponent Feedback

  We've been combing the forums and the Connect database for bugs, feedback and suggestions around the application model. We still have a small amount of time to consider any other feedback you may have. So this is the thread that you post your latest likes or dislikes with Game, GameComponent, services, etc. Please scan the other threads before posting here, I'd like to just gather things that haven't already been discussed or reported elsewhere. Thanks! One thing which i find rather strange is that the Game.Starting event seems to be raised after GameComponent.Start has been called. I only discovered this as i initialised the AudioEngine, SoundBank, etc in Game.Starting, but it was null in the Gamecomponent. Placing the Audio ...Show All

• Visual C# Custom Object, Typed DataSet or DataSet

  Hi All, I have a big project , which designs as 3-tier. Most of work is database updateing. Inserting, searching. Speed is not requested so much. Users are around 100. New DataFiled may be added frequently. Which is best regarding using Custom Object, Typed DataSet or DataSet I saw so much discuss and confuesed. Is anybody with true experience will share experience If using typed data set, it will be dangous to crash with later on recompilie Thanks a lot. I just wanted to share my views. Typed dataset is useful at time of development but it may be costly incase of performance DataSet can be used but it is having lots of things with it(Constraints, relations etc.), if you are not ...Show All

• SQL Server Errors using multiple parameters in a SQL Statement

  In an OLE DB Source in an SSIS package, we are having difficulties using multiple parameters in a SQL statement. Using a single ' ' works fine, but I've read that when you want to map more than 1 parameter you should use 'Parameter0, Parameter1, etc'. The problem is that when we use Parameter0 and Parameter1 and then try to map it, it says that the query contains no parameters. Can anyone help with the correct way to use multiple parameters in a SQL query that's part of an OLE DB Source task Thanks, Mike Neither Parameter0 or just 0 is working This is the SQL in an OLE DB Source. At one point, 0 and 1 caused the parameter mapping dialog to appear, but these others are not workin ...Show All

• SQL Server when is the appropriate time to fire t-logs backup

  Hi, Is it alright to run t-logs backup while complete or differential backup is still running in the background Objective is zero data loss and faster recovery time, which of the schedule is appropriate 1. full backup (weekly), then t-logs afterwards (round the clock, every 15 minutes), diff (daily) 2. full backup then differential then t-logs (round the clock,every 15 minutes) 3. full backup at the same time running the t-logs continuously, also while running diff backup (is this possible ) Jeff Irish wrote: maranbe, If zero dataloss is your goal perhaps you should be running a SQL 2005 Mirror.

• Visual Basic Check for encrypted match.

So how do I use the same key so that when the scrambled password on file, is compared to the scrambled password entered they will match Function encryptStringToBytes_AES(ByVal plainText As String, ByVal Key() As Byte, ByVal IV() As Byte) As Byte() ' Check arguments.
