• Visual Basic filling a bitvector32 in a loop

  Dear all, I can fill a bitvector32 like this: Dim InBytes As Int32 dim i for i = 1 to 1000000 InBytes = i 'for example Dim InBitVector As New System.Collections.Specialized.BitVector32(InBytes) next i and then I can read out the individual bits (need this for a graphics conversion). Problem: this gets VERY slow, and I trailed that to the Dim InBitVector statement. Is there ANY way to assign an Int32 number to the InBitVector WITHOUT using the dim statement Thanks, Kees Perhaps it's wise to say what I want in the first place. Perhaps you guys even know a way to prevent extensive coding in solving this problem. I have 12-bit gray-val ...Show All

• Software Development for Windows Vista Smartcard based authentication with CardSpace

  When choosing to use Smartcard based authentication with CardSpace, how does the transmission from the certificate between the smartcard reader and the STS takes place The Information Card specifies the thumbprint of the certificate to look for, but what is the exact technical background; does it just searches your computer's Certificates store and all smartcard drives for that certificate, and then sends it towards the STS Would like to know more about it, since nothing specifically seems to be documented about this feature I think I understand your problem a little better now and can see what you are trying to do. The bad news is, and hopefully I'm wrong here, is that this feature ...Show All

• Visual Studio 2008 (Pre-release) Introducing: ADO.NET Entity Framework Services

  Greetings, Just wanted to let people know about a little project I've put some time into, that has served as both a primer course for EF and Web Services (since I really didn't know either of both when I started!).  I call it ADO.NET Entity Framework Services, and it's meant to assist with applications developed with web service boundaries. You can find this project here: http://codeplex.com/entityservices This project helps developers to: 1) Create a "fascade assembly" based on a current EF-empowered assembly. 2) Load up an entity fascade based on Load Plans defined in configuration.  This fascade can then be sent over the wire to a remote destination. 3) Hydrate an entity object from an incoming fascad ...Show All

• SQL Server SSRS 2005 not closing open cusors in Oracle 9i

  The shared data sources in our reports are calling stored procedures in Oracle 9i that return data in out ref cursors. We are creating a bunch of snapshots (about 1400 of them) programatically using the Reporting Services Web Service method CreateReportHistorySnapshot. This works greate but we quickly got the Oracle error "ORA-01000 Maximum open cursors exceeded". The maximum number of cursors is currently set to 1500. Increasing the number of cursors is not a good idea because we have a subreport that executes an Oracle stored proc for each row in the main report and that would be a cursor for each row which would be about 5500 cursors in additon to the cursors we need for all the other snapshots being produced. We need to ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. loading a 3d character and getting it to walk.

  Hi there, I'm new to XNA, but have done a fair bit of game dev. How do I get a 3d character into XNA and play out animations on it, so it can walk around the scene. I have my character in 3dsmax / maya and can export it as .x file, but how do I do the rest. Many thanks Kam You will need the content pipeline to load characters and animations but it is not included in the beta, and probably won't be released until December. If you search for content pipeline in these forums I'm sure you'll find lots of info and similar requests ;) ...Show All

• .NET Development Debugging Custom Attributes

  Is there something special I need to do, in order to set a breakpoint and step through a custom attribute I have a class like this: public class SecureClass { [ApplicationPermission(SecurityAction.Demand, CustomPermissions.UserAccessPermission)] [MyTest] public bool WasSuccessful() { return true; } } And I was trying to set a breakpoint in the constructor for ApplicationPermissionAttribute, so I could debug it.

  what are the new controls (windows.forms) with .net 2.0 version Can some body give me the link or info related to above, I see few controls were obseleted in the beta version (eg: System.Windows.Forms.DataNavigator and System.Windows.Forms.RaftingContainer) and I am interseted in the list of controls supported in .net 2.0 released version.

• Visual Basic Unrecognized Database Format?

However, when I try to run it, it says Unrecognized database format 'C:\Documents and Settings\Mike\My Documents\Visual Studio 2005\Projects\CAD\CAD\CADdb.mdf'. Any ideas Thanks! If you made the database using VB Express then its likely a SQL Express database and not a MS-Access database.

• Visual C++ Visual Studio and ANSI standard

  I just got this book Teach Yourself C in 21 Days (which uses ANSI standard) and I can't get Visual C# to even use basic code like: #include <stdio.h> main() { printf( "Type stuff here" ); } Although, Visual C++ will, but even then some of the syntax isn't being read as legal code. How do I get Visual Studio to start using the ANSI standard... The ANSI standard is about the C language not about the C# language. You may want to look for a book about C# if you want to learn it. The equivalent of the above C code in C# is: using System; class Program { static void Main(string[] args) { Console::WriteLine("Type stuff here"); } } As for errors with Visual C++ that's because ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Intercepting Exit

  Is there a way to intercept and abort the closure of the Game window when the user clicks the close button Something similar to the FormClosing event for a Form window, where FormClosingEventArgs.Cancel can be set to true, if the user decides to change their mind and save their location, for example. I haven't found it yet... I'm just hoping I've missed it. Alternatively, can I disable the close button Thanks, Paul Sorry about that. I guess I was thinking of the minimize/maximize buttons. And Leaf, it's very annoying when someone comes along and reminds me of what a moron I am. ...Show All
