• Game Technologies: DirectX, XNA, XACT, etc. ModelMesh in regards to Effects and renderstates

  I just want to put this suggested change up for discussion, since I'm not entirely sure if it even is a potential preformance booster. As it is now Effects used by ModelMesh are cloned from the one loaded from the ContentManager. This is so that they can hold unique effect parameters set in, say, an .x file. In practice that means that even though a ModelMesh has two parts which use the same Effect they will not be the same instance of the Effect. As a consequence you can't make your own draw routine which draws all objects using the same FX file in a batch inside an Effect.Begin / End clause with just changing of EffectParameters and doing CommitChanges. I assume that approach would be much faster than calling them one by one in som ...Show All

• Visual Studio Tools for Office Slow performance while accessing MailItem fields using VSTO

  Hi, I'm developing a C# based Outlook add-in using VSTO 2005. This add-in collects information from multiple Mail items, so I've a simple code like this: Outlook. MAPIFolder inbox = this .Application.ActiveExplorer().Session.GetDefaultFolder(Outlook. OlDefaultFolders .olFolderInbox); Outlook. Items items = inbox.Items; foreach (Outlook. MailItem mailItem in items) { resultList.Add(new FoundMessageItem(mailItem)); //Takes some fields from the mailItem like subject, sender, recipient } Running this loop on even quite small mailbox (about 100 items) takes a long time (about 10-12 seconds) which is unexptable in my case. What can be done to improve the performance Thanks in advance, Maxim ...Show All

• Windows Live Developer Forums Newbie. I want to enhance the image quality.

  Hello, this is very basic, but I need to know the power and flexibility of this tool. I need to see in a superior level of detail, in 3D view, a city with a few mounts... ( I don't need buildings, just the terrain ) But everything that is at a certain distance from the camera looses quality (geometric detail level and image quality). I know this is done in order to increase render speed, to save memory and bandwidth... but I need more quality, and I'm ready to pay the cost. Is there a workaround to increase the quality, someone knows a website, parameter, anything that might help me please I need it, even if it takes quite a long time to display one single image. I need excellent quality. Thanks in advance! Albert G ...Show All

• SQL Server Restore 2005 to 2000 Database

  The machine I do development on has SQL Server 2005 installed. My client, however, is running SQL Server 2000. When I tried to restore the database, I got the error: The backed-up database has on-disk structure version 611. The server supports version 539 and cannot restore or upgrade the database. How can I restore a SQL Server 2005 database to a SQL Server 2000 database it is possible when you export the data from sql2005 then import to SQL 2000. An alternative method for this is to create 2 named instances within same computer. 1 for SQL 2005 and 1 for SQL 2000 on the same server. Then export DB from SQL2005 to SQL2000. Afterwards backup your database in SQL2000. It worked for me.. Yes i agree i ...Show All

• Windows Forms Building a Form Manager

  Hey All, I have seen numerous posts where people mention building a form manager to keep track of open forms and other settings. Can anyone point me to an example of such an animal I want to build a manager that when a new form is opened, it is stored in the central location. I also want to be able to go to a central location to check the "Current User" as this is an application class, and is easily and frequently switched on the fly by the user. Basically a central location to go to that is up to date with the current environment. However, I am not quite sure where to start, and an example of one would be nice. Thanks, Hammy OK.

• Windows Live Developer Forums Status property on AdCenterCampaign

  Hello, When are we going to get the status property on the AdCenterCampaign object I can pause and resume a campaign using the UI. It's very anoying that we can't see this using the API and that we cant pause/resume a campaign. Simulating campaign pausing, by pausing the orders is an ugly hack, when you guys could probably implement campaign pausing/resuming in 15 minutes on your side. Best regards, Peer Jakobsen I didn't know you couldn't pause or resume orders once the monthly budget is spent. That is a huge problem, I'll have to look at that. Have you verified this lately, or was this an older issue I seem to recall our MSN contact saying that had been resolved, but I haven't verified ...Show All

• SQL Server Automatic failover failure

  Hello, we're running a mirrored database with High Availability for Automatic failover including a Witness instance for a web application. When doing a manual failover on the database in Management studio, the roles are switched correctly and the database is in "Principal, Synchronized" and "Mirror, Synchronized/Restoring" mode. The web application has no problems switching servers by using client failover with the jdbc driver. There is no problem accessing the database with Management Studio. However, if we stop the SQL service on the Principal server the role is automatically failed over to the Mirror server by the Witness. The database is then in the mode "Principal, Disconnected" which should be f ...Show All
