• Game Technologies: DirectX, XNA, XACT, etc. loading textures "in game"

  Hi I know how to load a texture when the game starts, but how to load a texture when the game has already startede ex. 10 min in the game You can call content.Load<>() anytime, and anywhere, in your code. Say you want to load a texture after the player has passed a certain position: if(player.Position.Y > 1000) content.Load<Texture2d>("JustAnotherWall"); You aren't required to load all your assets inside LoadGraphicsContent; it's just good design/habit. There are two types of loading resources - automatic and manual. Automatic is through content.Load<>(), and whenever you call content.Unload(), it will dispose of everything properly for you. Manual texture loading i ...Show All

• Windows Forms Multiple Publishing Locations?

  I have a project in Visual Studio 2005 that I want to push out to our two sites. It's going to be much more efficient if I can transfer the necessary files to two separate network folders, each on a PC in a different office. Is there an easy way to do this or will I just have to publish it to one and then publish it to the other one Can I get VS2005 to remember both destinations I assume I won't be able to publish it to one place and copy the files to the other manually as the application will look in a certain folder for its updates... Any thoughts on this from anyone Cheers James, There are a couple options for publishing an application to multiple locations. The first is to use VS for both ...Show All

• Visual Studio Team System How to check if a build (in a team project) is currently processing?

  I'm having some trouble with how to check if a build is currently working within a specific team project. The Team Foundation Build Server can only build a single team build at any given moment, for each of the team projects. Right now I'm using the following code to see if I'm allowed to start a new build or not: try {      buildUri = BuildController.StartBuild(buildParams); } catch ( Exception ex) {      if (ex.Message.StartsWith( "TF42045" )) If this happens, I schedule up the build so it will run when the current build is done processing. At the end of a build process, I'm sleeping the thread for 1 second, even though the build is completed, it sometimes throws exce ...Show All

• SQL Server Report Model Generating Out of Memory Error

  I am creating a report model of a large database with a few hundred tables, the idea being that the users can report on any part of the database and create perspectives for the areas they want users to have access to (In the past the users have moaned about report models in a CA product called Eureka as the models are too small, perspectives seemed a way of allowing one large model but limiting each perspective to a set of users ). Unfortunately presumably due to the size of the model visual studio is giving me an out of memory error when adding new tables. I have a two dual core xeons with 4Gig of ram and I'm running XP Pro 64bit with the developer edition of 2005 with service pack 1 and VS2005 is using around 1/2 a Gb. Is this a known i ...Show All

• SQL Server Application roles and Module signing

  Hi, Am migrating my SQL 2000 legacy app to SQL2005 and am dealing with restrictions on the underlying system tables. Have taken advice that Granting VIEW state to all users is heavy handed (especially meta data access at SERVER level). Now looking at Module signing which is great. I can supply SP's which target the few System table/ information schema fields that I require. Now I Sign the Sp's cool, now I grant exec rights to the application role (doesn't work). Create a db role and put my users in it, okay grant role exec on Sp's (fine they work). However my application runs under an application role always, so my users rights are ignored and it appears that its only the users not the approles who can benefit from the module signing I ...Show All

• Visual Basic Creating MSSQL Tables from DataTables

  Hey everyone, quick question, I'm populating a datatable on a client based on data out of a local database on the client systems, it than pushes that datatable to a webservice where I would like to recreate that table on the server. Originally I was going to push generic lists to the server to track column names, column types, column lengths etc. but than I figured the datatable has all that information in it already, problem I have is actually creating a MSSQL table based on this datatable. If you query the column datatype properties from the datatable the types come out different than the types that MSSQL requires such as the datatable pumps out "system.int32" for what the database considers simply a "real" number.

• Visual Studio Team System How to ignore compiler-generated members?

  Our company has rule to prefix all class member variables with ‘m_’. When I try to make a custom FxCop rule, it will pick up all compiler-generated controls’ names (starting with underscore) in the web application (VB). How can I make it so custom rule will ignore them Thanks... Hello Alex, You are right. RuleUtilities.IsCompilerGenerated(Local) will help only by locals which were generated by compiler while compiling the source code. In your case the variables/fields are generated on the source code level, so they will remain with the same names on the IL-Code level and RuleUtilities.IsCompilerGenerated(Local) method will not work.  You could search for all fields which start with p ...Show All

• Visual C# Process class used from Windows Service fails

  I'm having trouble with the Process class. I have a Windows Service running as SYSTEM and I want it to spawn processes on behalf of users. I get the user's password there securely and create a SecureString. I get a Win32Exception "Access Denied" on Process.Start. If I run the service under the same account as the user I want to start for, I still get the exception except it says "The handle is invalid". I've checked and checked the SecureString and I've made it read-only so I don't think that's it. I actually had gotten it to work some time ago if I impersonate the client but this isn't really practical since the job can be queued up waiting for some time. I've signed all the assemblies involved and I've given the ...Show All
