• SQL Server Can you setup backup/restore functionality in SQL Express 2005 from a C# app?

  Hi, I'm currently working on a project which uses a SQL Express 2005 database. I want to be able to setup SQL Express from my C# program so that it can perform backups to a specified path location at the requested interval itself. This would free up my program from having to manage the backups. Just wanted to know if this is possible Also, when the current database becomes corrupt will SQL Express perform the restore for the user automatically, instead of them having to manually request a restore I realize that it might not be able to handle the restores in the same way as backups, but I figured I'd at least ask. Thanks, ...Show All

• .NET Development Developping a Real-Time Application

    Hello NG! I have to develop a Real-Time application. Computer A writes a message to computer B and computer B should get the message in real time (or almost real time). The message should be stored in a SQL-Database. One way is that computer A stores the message in the database and computer B is looking every 5 or 10 seconds if there is a new message. But I think there are better ways to do this, aren't they Is it possible to develop a Real-Time Application with .NET If yes, what is better winform or a web-application What kind of methods are out there Are there any samples out there Thank you for every idea!

• Game Technologies: DirectX, XNA, XACT, etc. Which software to use, to author .x files?

  I've come to the point in my 3D application where, I have created all basic 3D stuff and rendering 3D primitives with textures. It is time to import .x files and render them. I used the tiger.x and tiger.bmp and the code from the Meshes tutorial and it worked fine. But what I want to do is create my own .x files - textures applied. Also, the Meshes tutorial says that D3DX can only handle the geometry and we have to setup the textures and materials for the mesh. What software should I use to author .x files and apply textures to them Any freeware or shareware will be helpful because I don't have money to buy commercial softw ...Show All

• Windows Live Developer Forums Double BOM Problem Still Exists

  FYI the response from XML-RPC method blogger.getUsersBlogs is not valid XML - it has two BOMs. I've not tried any other methods. This is a bug that should be fixed after the holidays. It would be fixed sooner but (a) the developer is on Xmas vacation and (b) we tend not to make changes to the site over the holidays since so many people are on vacation in case something goes wrong. Sorry about that. :( ...Show All
