• SQL Server Retaining Fields for Multiple Models in Mining Model Prediction Tab Design View

  I am using BI Dev Studio for SS2005 in a research (as opposed to a production) environment. Often I want to compare the results of multiple models using the same attributes. If I switch to a different model, the Design view completely resets. Is there any way to retain the same field names with different models in the Design view My current workaround is to give my models similar names with AR, DT, CL, LOG, NN suffixes and make global changes in the DMX. I have consulted the following without finding an answer: http://msdn2.microsoft.com/en-us/library/ms178445.aspx http://msdn2.microsoft.com/en-us/library/ms175642.aspx http://msdn2.microsoft.com/en-us/library/ms175678.aspx http://msdn2.microsoft.com/en-us/library/ ...Show All

• Visual C# Override Attribute

  It’s possible override a attribute Example: public class CBase { [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public virtual int Prop { get { } set { } } } public class Test : CBase { [Obsolete("Dont use this property!", true)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] public override int Prop { get { } set { } } } This is don't work, any ideas Thanks in advance Yes you can override attributes but it doesn't necessarily mean it'll work in all cases. For example if you override the CategoryAttribute it'll work (I believe). It really depends upon the caller. The callers can opt to retrie ...Show All

• Software Development for Windows Vista Local Session Manager Service

  I would like to understand the use and nature of this process. It's been started by WinInit and runs under SYSTEM. The reason why i'm interested in this process is that I have noticed that the memory usage (private bytes) keeps going up while my application is running. The private bytes also does not come down after the application exits. My application is written in C++ and uses the Media Foundation API. What is also interesting is that I can recreate the same situation using straight up samples from the Vista SDK 1.0. Anyway, it would be good understand what makes the memory of this process go up and more importantly not go down. Thanks! ...Show All

• SQL Server Parameter maximum string size question

  Does anyone happen to know what is the maximum string size that can be passed in a parameter w/o it truncating or throwing an error Thank you in advance, As it is implemented as a .NET type (System.String) it could take theoretically up to 2^31-1 chars, but passing the parameter through the webservice or the URL will make you only to have your URL expanded to the maximum of 2083 chars to support all the methods like GET / POST / Webservices. http://support.microsoft.com/default.aspx scid=KB;en-us;q208427 HTH, Jens Suessmeyer. --- http://www.sqlserver2005.de --- ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Heightmap Terrain Component

  I thought the whole component concept was pretty cool. So I threw together a quick heightmap terrain component. http://i9.photobucket.com/albums/a59/craigory666/heightMapTerrain.jpg http://i9.photobucket.com/albums/a59/craigory666/heightMapTerrain2.jpg http://i9.photobucket.com/albums/a59/craigory666/heightmapprop.jpg It should work with square .raw files, and for the effectPath I'm just using the default texture shader found in the help file. The view and projection matrices of the terrain are exposed, so you should be able to hook up whatever camera you have going and just update the terrains view, and projection matrices during your games update. using System; using System.Collections.Generic; using System.IO; using Microsoft.Xna.Fr ...Show All

• SQL Server How to edit someone else's report definition?

  I need to be able to share report definitions with other people in my group, so we can all edit and makes changes to each report definition if the need arises. When I tried to use a shared folder the other person could not access my report def, so evidently there is security applied. What's the correct method to do this Please point me at the documentation if it's listed somewhere - even an MSPress book would be fine. This is for both SQLRS2000 and 2005. thanks Peter OK - further forward progress, however the data source apparently does not bring over the credentials so I assume we'll have to enter them again manually. thanks!! ...Show All

• Visual Studio Express Editions How do I specify Data files for ClickOnce deployment?

  Hi to all, I have an application that uses 2 CSV files. The application sucessfully runs on my development system, but bombs when Run after ClickOnce deployment.

• Visual Studio 2008 (Pre-release) TreeView DataBinding

  Hi! I'm using a TreeView which content is filled with an XmlDataProvider through its ItemsSource property. I still can't get how this really works. I believe that the treeview never creates TreeViewItems instances when filled this way. My application lets me select a node, and then execute an action that makes me refresh the tree. What I'm doing is resetting the XmlDocument in the XmlDataProvider , and the treeView gets refreshed automatically. The problem is that the treeView is reseted and I loose the selected position. Some more details: I changed the treeview and treeviewitems styles and templates. I'm able to change some properties (like color) from the TreeViewItems in that styles definitions. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Assets load in a thread

  I am started a system of load of assets encapsulating in a thread the ContentManager. I can be loading assets in asynchronous way in parallel with the thread, or can loads asset synchronously when I need it in the main thread. I have several problems to continue with this system. If I call to LoadAssets from 2 different threads with equal asset at time an exception jumps. I have tried to put mutex and works well, but in synchronous way I must waiting finish the current request of the thread to be able to load asset from the main thread. I have several questions or doubts: If I make a dictionary with assets loaded to be able to call to LoadAsset, It's consistent with the ContentManager If the games were loaded of hard disk, I r ...Show All

• Smart Device Development Cannot explain diff in values returned from CTime::GetCurrentTime and ::GetLocalTime

  In using the three methods CTime::GetCurrentTime ::GetLocalTime ::GetSystemTime Using VS2005 Beta 2, I get three different values, respectively, when the local time is 11:58, 2005-11-25: 2005-11-24T15:58:12 2005-11-25T11:58:12 2005-11-24T22:58:12 . Time Zone Information via ::GetTimeZoneInformation shows Bias: -720 Standard bias: 0 Daylight bias: -60 So from all of the above, I can explain the diff in the results between ::GetLocalTime (local time zone == UTC + all bias) and ::GetSystemTime (UTC). But why the diff between ::GetLocalTime and CTime::GetCurrentTime I would have expected these to be the same.
