• Game Technologies: DirectX, XNA, XACT, etc. directx as math library

  Was wondering if anyone knows of any problems with using the directx library as a math library since there seems to be a lack of a complete math library included in visual studio c#. This is for an engineering app so precision is needed. D3DX is a very good maths library for graphics-related maths. Although, I'm pretty sure it uses single-precision floating point numbers. If you want double-precision you're out of luck. It's also worth noting that ( as with most of DirectX ) it's optimized for performance over accuracy - small losses of accuracy don't usually matter for games, so we don't complain!

• Visual Studio Express Editions Cannot install visual C# express edition

  Hi, Hope someone can offer some suggestions as to why I cannot install C# express edition. I have followed all the installation instructions and just cannot not figure out why it won't install- have no firewalls, Antivirus, or unwanted services. I have a raid system- mirror and an eVga SLI vga card (I'm not using that feature). Wonder if that has anything to do with it. Any help will be appreciated.

• SQL Server How to generate a report containing multiple single page reports

  I am using SS 2005 RS. I am able to generate single page pdf reports by passing "id" as a parameter. Now I need to send multiple ids as parameter and generate one big report which would contain reports for all the ids supplied on separate pages. Is this possible If yes, then how do i do this. What I have tried so far is, I created new report with a list control and added single page report as a subreport to this list control and grouped this list control using id parameter. When i send multiple ids in the parameter, for example 3 ids, it generates 3 page report but only for the first id. So it generates report for the first id a ...Show All

• Visual C# Constructing an ENUM from a simple ResultSet

  Hi all, Is it possible for me to Construct an ENUM from a ResultSet returned from a Database. For example, I want the following ENUM... /// <summary> /// A list of all filter types, Status. /// </summary> public enum StatusFilter { All = 0, Open = 1, Complete = 2, Unfinished = 3 } Where I want this to be identical to what is returned from my Status's Lookup table, where I have four entries (along with their primary keys). Basically, what I want, is to be-able to filter rows in a ListView by clicking on a specific ColumnHeader on the ListView. So effectively I want to be able to cycle through the status' (o ...Show All

• .NET Development Looking for an absolute definition of "Local Time"

  The expression "Local Time" is thrown around a lot in the MSDN documentation.  When it is defined, this is the standard definition (example taken from the documentation for TimeZone.ToLocalTime) : Local time is the date and time on the computer you are using Is this absolutely always the case, with no ambiguity   In particular, since the Start and End properties of DaylightTime are defined as being in "local time," does this mean that a DaylightTime for Pacific should return different Start and End values in Denver than in Boston (requiring a time zone conversion be performed on the very structure that supports time z ...Show All

• Visual Studio Tools for Office Excel Constants

  Dear all, I can get the maximum limit of Excel (vary on different version) by using, e.g. Rows.Count and Columns.Count), and I'd like to know how I can get the maximum number of character per a formula (E.g. 1024 for Excel 2003), or more generally, how I can get all Excel build-in constants Thanks, AFAIK, it does have a limit (everything have a limit :) For example, we can enter a very very long formula in a Excel cell, otherwise, a "Formula is too long" will be thrown. Moreover, there's a 255 characters limit per argument for an Excel function/UDF. Try it out and what I'm looking for now is to re ...Show All

• .NET Development Connect to internet from my Application

  Hello: I'm working in VS2005-C# and I have an application which connects to a web service. I'm looking for some managed code approach to check if the computer is connected to internet and if not connected start a connection. My idea is to avoid the user the work to go to Dial-Up connectios and start the Dial-Up assistant by hand. So far all that I've found is by using API calls to wininet.dll. Is this the only one solution or there is some managed approach(meaning Framework classes doing this) Thanks in advance ...Show All

• SQL Server Secure Social Security number in my DataBase

  Hi, i have a data base in SQL 2005 and i it has many tables with confidencial information Like Social Security numbers, Credit card Numbers, etc. And i would like to encrypt this information or make something to make this info invisible to any hacker, or any person that logs on the server.

• Visual Studio Team System problems with shared checkout - merge tool is not available

  I am having a significant problem with TFS version control that is making it very unusable in our development environment. We are allowing multiple checkouts. When two developers work on a file and check it in, the Merge option is unavailable and the auto-merge functionality is failing. This makes the product practically useless for projects that have more than one developer. Here is the scenario: TFS set to allow for multiple checkouts. 2 developers working on the same project.
