• .NET Development Check if the database exists

  Is there any function in ado.net that I could use to check if a database exists in the server like SQL 2005 I already knew how to performing this checking in T-SQL, but I want to know the ado.net way of doing it. Hi Another approach which has just come to mind is to use the Microsoft.SqlServer objects. You will need to add a reference to Microsoft.SqlServer.ConnectionInfo and Microsoft.SqlServer.Smo and then you can use the following the code to retrieve a collection of databases from a specific SQL Server instance. This should work for both SQL Server 2000 and 2005:         Dim dbServer As New Server( New Microsoft.SqlServer.Management.Common.ServerConnection( "(local)" ))   & ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Some questions about XNA & 2D games

  Hello, world. I have limited experience with programming, but I've been doing some hobbyist programming of late. I wrote a couple text adventures (in Inform 7 and TADS 2), and for the last couple weeks I've been trying to learn the basics of Visual C# Express Edition. I've watched almost all of Bob Tabor's excellent "Beginner's" videos on C#, and I feel pretty comfortable with the syntax and structure of the language. I'm interested in starting with a 2D hex-based wargame, although my grand ambition might be a turn-based wargame that uses 3D terrain, or perhaps a 3D adventure game a la Nancy Drew. I've been tootling along, whipping up a primitive little wargame interface using the visual designer in Visual C#, and I have a few qu ...Show All

• Visual Studio Team System VSTS 4 DB: SSAS integration

  Suggestion about features for the new VSTS 4 DB (data dude). It would be nice if we could use the tool for analysing schema changes impact throughout the BI workflow. SQL Data warehouse shema -> SSIS packages -> SSAS Database,SSRS report models A VSTS solution can contain a project for each one of these. A change in the model of the data warehouse ofthen results in many cascaded changes in other components. So a tool that could list all the references where a field is used outside the SQL server RDBMS (meaning SSIS, SSAS en SSRS) would be a powerfull development tool. With feater like make a check list of these references that you can check off one by one, when you click on them you jump to that reference for revieuwi ...Show All

• Visual Studio Team System Build a Solution on a remote machine

  Hello! I want to achieve the following: - Check out a source file - Change a source file in a solution (TFS is installed as a single-server solution; Application and Database on same machine) - Check in the source file - Compile the solution Sounds easy, right But: I want to build the solution on a separate machine (not my client machine where I have VSTS installed), and not on the machine that has the TFS (we don't want to slow down the TFS machine). What I have to do Is there a documentation for such a scenario Note: The separate machine does not have TFS installed currently. There are only some databases (in virtual machines) installed for testing purposes. Best regards CSharpNewbie22 ...Show All

• SQL Server DR: Replication vs. log shipping vs. clustering vs. database mirroring........

  Up to now we have gotten by without having any local DR copies of servers (if a sql server goes down we are usually able to get it back in less than 3 hours). But I want more now. I want to trim the "down" window to no more than 5 or 10 minutes. (Immedate failover would be nice but is not an essential requirement. The essential requirement is to loose no data!) I have a spec of knowledge in these areas: SQL 2005 Clustering (requires approved hardware, quorum disk, etc. involved) SQL 2005 Replicaiton SQL 2005 Log Shipping. SQL 2005 Database mirroring. ( needs three servers) Which approach do you think is the most straightforward, sparing of hardware, yet reliable way to get us back up and running after a sq ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Bug in BoundingFrustum.Contains()?

  If i write the following code: BoundingFrustum f = new BoundingFrustum(new Matrix(1, 2, 3, 4, 5, 6, 7, 8, 9, 8, 7, 6, 5, 4, 3, 2)); Vector3 vector = new Vector3(1,1,1); BoundingBox box = new BoundingBox(vector, vector); ContainmenType t; t = f.Contains(vector); Console.WriteLine(t); t = f.Contains(box); Console.WriteLine(t); I'd expect both to give the same answer. Either both are contained or both are disjoint. However the Frustum contains the point but the box is disjoint. What's going on A compiler cannot silently drop code that works on 0 volume BoundingBoxes. How the hell would the compiler know if i *need* that box or not Sometimes a compiler using to be a clever beast. You can follow t ...Show All

• SQL Server Problem merging two distinct reports having similar paramters

  Hi All I got two separate reports with similar type of and number of parameters. Let’s name our report so that I can explain it well, Report One; Student Marks Sheet and another Report; Student Remarks Letter. I want to merge these two reports because their parameters are just a copy of one another. I have tried to merge Student Remarks Letter as Sub report of Student Marks sheet but it has not worked. The scenario is so that Student Marks Sheet paper size is A4 in Landscape style and Student Letter Report is A4 in Portrait style and Student Letter Report is to be printed on Headed paper. Having merged the Reports, When viewed via report manager the Student Letter report paper size got changed according to its parent report ...Show All

• Windows Forms Recommendations for a real time updated grid

  I have an application with a grid which is updated in real time. The grid may be updated many times a second and I'm trying to decide on the best way to handle the updates. I've considered using two datasets, one which I would perform updates on from non form threads, and another which would be bound to the datagrid. I would then put a timer on the form, which would update the dataset attached to the grid once a second. Since the timer's callback is in the forms thread, I don't have to worry about threading issues when updating a datasource from an external thread. The benefit of this method, is that I can update the data which is used for calculations as often as I need for making calculations without making the form interaction slow. Ano ...Show All
