• Game Technologies: DirectX, XNA, XACT, etc. No ID3DX10Line?

  I do not see any documentation for a D3D 10 version of ID3DXLine. Granted the DX9 ID3DXLine interface is a complete joke -- both in performance and quality, at least there is a way to get a few stylized lines in the 3D view. While games don't use stylized wireframe, this is a cornerstone for profession graphics packages (e.g., modelling and drafting). Current hardware supports accurately rendered, deterministic zbuffered, accelerated lines with widths up to 5 pixels wide. Common screen space dash patterns are sufficient for 90% of all display purposes. There are also several hidden line algorithms that only function correctly if the wide lines are rendered with correctly depth buffered Bressenham step patterns. Until Direct3D provides acce ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA Express - Windows XP Home Support?

  I've been looking around and trying to determine what version of Windows is needed to be able to install and run XNA Game Studio Express. My main question is whether or not it will work with Windows XP SP2 Home Edition. The FAQ just states Windows XP SP2 (as I've pasted below). I have in the past tried to install programs that say they work with Windows XP SP2 only to find that they really mean Windows XP SP2 Professional edition. They wouldn't work with Home edition. I'm assuming that it will work since it's an Express edition, just like all the other .NET language Express editions, but I just wanted to make sure. I don't want to have to upgrade my machine if I don't have to. (And please, no arguments about why I should upgrade to Pro. I ...Show All

• Visual C# generics in constructors

  Hello, I have a question about generics in constructors. Assume I have two constructors, e.g.: public Constructor1(string param1, string param2) { ... } public Constructor2(T param1, string param2) { ... } This will compile without problems (by contrast, I'd get a compile error if I had "public Constructor2(string param1, string param2)" because there would be two constructors with "string, string"). However, if at runtime I call Constructor2 with the generic parameter as a string, I get runtime problems (because Constructor1 and Constructor2 cannot be distinguished). Does anyone know how to deal with this in a clean way I know that I could, for example, change Constructor2 to something like "Constructor2(T param1 ...Show All

• Visual Basic Overriding Enum members

  How can I override or overload Enum public methods e.g CompareTo or ToString There is a specific reason why I want to do it with enums... Enums make the process of defining a number of values form which a vraiable can assume one, a lot easier. In addition, the symbolic constants also increase clarity. Now, my problem is that I want symbolic constants with spaces in between them, like... Enum Sample Sample Text1=1 Sample Text2=2 Sample Text3=3 End Enum So, now can someone suggest me a way to do it with enums. (Now, it should be pretty clear why I wanted to override ToString, to return strings with spaces)... ...Show All

• .NET Development ignoring namespaces in xslt

  Hi all, I have an xml file that I am trying to run through XSLT, but the namespace on some of my source objects are causing the xslt to not find the node. Can't I tell xslt to ignore the namespace xml file snippet: <Shipping xmlns="http://soa.channeladvisor.com/webservices/"> <NameTitle>Mr.</NameTitle> <FirstName>John</FirstName> <LastName>Doe</LastName> </Shipping> xslt snippet: <xsl:value-of select="ShippingInfo/NameTitle" /> If I delete the namespace from the Shipping node, my xslt works fine.

• Architecture Use serialized domain model entities as web service messages?

  I am wondering about the viability of using domain entity classes as the return types and method arguments in web services. The motivation is to avoid having to create a layer of data-transfer/message classes, and the mapping of domain objects to/from them. Technically it works - the IDE autogenerates the proxy classes and does all the serialization. But when you get into the particulars of the domain entity classes (their relationships with each other, aggratetions, exposed collectons, etc), I can see there being practical problems. This is done fairly commonly but it seriously compromises the principle of loose coupling because both the caller and the service must have the class definition to be able to ...Show All

• Windows Forms Problems with PrintPreviewDialog

  I have the following code: try { printPreviewDialog.ShowDialog(); } catch (InvalidPrinterException e) { MessageBox.Show(e.Message); } When it runs on computer where no printers installed, I get error message as expected. But when user selects the same function second time, the following exception is shown: System.InvalidOperationException: Form that is already displayed modally cannot be displayed as a modal dialog box. Close the form before calling showDialog. printPreviewDialog is the same instance as in first call. I can solve this problem by disabling menu item, using another dialog instance or handling InvalidOperationException.

• SQL Server SQL 2005 Index Issue – General Network Error

  Info: CE.Net 4.2 CF 2 SQL Server 2005 First of all, sorry for the cross post but i need a quick answer on this. I am executing a CLR Stored Procedure from a Windows Mobile device and regularly get a general network error. The stored procedure cycles through up to 70 tables, checking for any records between two dates. The LastUpdate field is in each one of the 70 tables and is indexed. The mobile device regularly reports general network error, which is due to a timeout. Command timeout is now set to 10 minutes but the timeout still occurs. The stored procedure appears to get stuck on a particular table. If I rebuild the index on this table, it will get pas ...Show All

• SQL Server Connection manager validation within UI

  Hi all, I need to validate a custom connection manager within its custom user interface, like the FlatFileConnectionManager does it, by showing errors and warnings at the bottom of the window. How can I do that since SSIS provides only a ConnectionManager object with the IDtsConnectionManagerUI::Initialize method, and this object doesn't contain any Validate method Note that for a custom data flow component, SSIS provides a ComponentMetaData object which supports a Validate method. Thanks. Pascal I can't call the Validate method of my custom connection manager because SSIS doesn't give me my object but a ConnectionManager which is not a ConnectionManagerBase type... ...Show All
