• SQL Server Does it increase performance to use multiple datafiles for large databases

  If you've large databases (above 200GB/file). Does it help to have multiple smaller files (For e.g four 50GB files) Does it improve performance. Also if a single table (size 200gb) is alloted to a file group which has one datafile. Does it help to have such filegroup with multiple files (fore e.g 4 files of 50GB each). My thought was if SQL Server is looking for certain data (assuming the file is not very fragmented) it is better for SQL Server to load up only the specific file that corresponds to the data, instead of loading up an entire 200gb file. A lot of this depends on what kind of storage you have, whether is direct attached storage or a SAN, and if its a SAN, what kind of SAN it is. Genera ...Show All

• Visual FoxPro Using server's date/time.

  Hi; Is there a way to make VFP use the server's date/time in the different date functions I have XP stations on Win2003 server and some machines sometimes have a messed up date. Transactions are updated with the incorrect date because the stations are not set to the right date / time. Thanks, Aleniko Wrong:) Try creating a file on a remote machine. It's stamped with that machine's datetime. Station finds out the server's time by checking the file's creation time. ie: GetTimeFromMyServer('\\myServer\myShare') && has RW access - like a data folder * Get time from server FUNCTION GetTimeFromMyServer(tcServerPath) Local lcTemp As String , ltNow As Datetime Local Arr ...Show All

• Visual C++ Source browser and intellisense dont work in a solution

  If my solution only contains one project then the source browser and intellisense work fine. If my solution contains 2 or more project where one does depend on the other, then the intellisense and source browser are not functioning correctly. Is there a 'solution' to this or is it a known bug or limitation Thanks.

• SQL Server Need to Subtract the result of two stored procedures

• Windows Forms Bound ComboBox not displaying correct value on form load

  I have a form whose fields are bound to a table. I have one lookup ComboBox, MfrIDComboBox, which is bound to a field called MfrId. The ComboBox is populated from a datatsource on my form. The ComboBox popluates with values fine, and if I select a value and update the record, the correct value is saved to the database. However, when the form loads, the correct value is not displayed. I have tried everything I can think of, inlcuding setting the value with the following code. Me .MfrIDComboBox.SelectedValue = dr.Item( "MfrId" ) For reference, here is the generated code from the designer. Aside from the code above, I am not adressing the ComboBox programatically at all.

• Game Technologies: DirectX, XNA, XACT, etc. Managed DirectX Sprites: Is it possible to light them?

  Hi, Does anyone know if it is possible to apply Direct3D lights to sprites constructed using the Sprite helper class in Managed DirectX Since the class creates a quad for the sprite, I would have thought it possible to light the quad or rather the quad's texture. I have tried adding a light to my sprite scene and have tried doing this both before and after drawing the sprites. However, I cannot seem to get the lights to work. I have used the following code: // This is in my initialise section: m_Direct3DDevice.RenderState.Lighting = true; m_Direct3DDevice.RenderState.ZBufferEnable = true; // This is in my render loop: m_Direct3DDevice.Clear(Microsoft.DirectX.Direct3D.ClearFlags.Target, Color.Black, 1.0f, 0); m_Direct3DDevice.BeginScene(); ...Show All

• SQL Server SQL Express user permissions?

  I'm trying to build a web application using SQL2005 Express and Visual Studio Express.  It all works OK on the local machine, but gives an error "Login failed for user xxxx\ASPNET" when used remotely.  I can't find where I can set login permissions for SQLServer 2005 Expresss - can anyone help, please Thanks John This looks like a problem in the login control. The error reported probably has nothing to do with the actual error. The "login failed" error should always be logged to the errorlog file, if it did indeed happen. Probably the control is reporting incorrectly the error. Try contacting the VS team if this is a VS control. From what you have told me, there seems to be no problem with how ...Show All

• Visual Basic MDI child forms problem: Minimize button acting as Restore button with second child.

  Hi, Having a strange problem with an MDI application I'm developing. The child form is set to be maximized for the initial window state. When I create the first child, it is shown as maximized like I want. And when I click the Minimize button, it minimizes as I want. But here's the problem. If I create child one and then create child two with both with a WindowState of Maximized, and then click the Minimize button, the active child form changes to "almost maximized" as if I had clicked the Restore button instead. If I click the Minimize button again, it will minimize properly. If I instead click the Maximize button to maximize the form and then click the Minimize button, it will minimize properly. I hope I'm making sense ...Show All
