Game Technologies: DirectX, XNA, XACT, etc. A VERY simple question. I'm obviously missing something -er- obvious
Ok firstly, please forgive what MUST be a simple simple question... I've done the From DOS/BASIC->QBasic->VB3----->VB6 as well as some delphi, C, C++, lost of PHP a bit of ASP, some MySQL and some MSSQL, So I didn't think VS2005 would be a real problem (and after a month I'm starting to get my head around it), however, I devided to make a program to start learning somethign 3D-ish.

SQL Server how to excluded the intersection of 2 dimensions ?
Hi, I have the following simplified problem. I have a fact table and two dimension tables, colors and weekdays. I can make a query to select all except red and all except on monday but I like to make a query to select all except red mondays They query tool doesn't give you really the options. Any suggestions Constantijn Enders You can do it in MDX, but only a few query tools will allow you to construct queries like this. I think vendors tend to refer to this capability as 'asymmetic sets'; I can only think of one tool I've seen recently that did this (Intelligencia - http://www.it-workplace.co.uk/i4wfeatures.aspx ) but I'm sure that if you hunt around there will be others.

Visual Studio 2008 (Pre-release) propagate an exception of a concrete type in Indigo
Hello everyone from Spain, I am trying to propagate an exception, whose type is ExcepcionConcurrencia (it is Spanish). Well, the issue is that it doesn't propagate the exception of the type that I have defined, it propagates ServiceModel.FaultException. I need my type because I propagate a DataSet in it. I have tried using the ServiceKnownType Tag but it doesn't work. How could I achieve it Thanks in regards Hi, You need to annotate your ServiceOperation with a FaultContract.

SQL Server Special Characters in a Dropdown List
I have a web form that needs to be bilingual. It contains several dropdown lists. The "text" and "value" for each item in the dropdown list is retrieved from a database. The logic reads the database and then populates the various dropdowns with logic such as: dim newItem as new ListItem(textString, valueString) theDropDown.items.add(newItem) The problem that I am having occurs when the textString needs to contains special characters such as accented vowels or an "n" with a tilde. I have tried populating the database with HTML-formatted strings such as "Avión", hoping that this would display "Avion" with an accute accent over the "o". Unfortunately it displays & ...Show All
Visual Studio 2008 (Pre-release) Dlinq and Gridview
Hello, I was wondering if anyone has any success trying to bind an object datasource that uses the underlying DataContext classes to a GridView. I am particularly having problems with an update. I have a class called MenuItem which was generated using SqlMetal. I have a list of object instances of this class bound to a GridView. The ObjectDataSource requires that the UpdateMethod take a parameter of a specific type if the DataObjectTypeName property is specified or a set of updated parameters. I have used the former implementation and specified the type MenuItem for the DataObjectTypeName property. I have created another class which delegates to the SqlMetal generated DataContext class on an update. This class implements a function w ...Show All

.NET Development How to serialize back a ConfigurationElement object?
Hello In the System.Configuration namespace you have several classes (like ConfigurationElement) which help you to deserialize custom configuration sections into objects. Now I have an object from a class which derives from ConfigurationElement and I'd like to serialize it back into its original xml state because I'd like to write it to a trace output (XmlWriterTraceListener). I tried to use the XmlSerializer to serialize the object but this did not work. I got the following error: You must implement a default accessor on "MyProperty" because it inherits from ICollection. Any other ideas how to achieve this The framework already has a builtin mechanism to deserialize the custom config section. Maybe it's somehow possi ...Show All
