• Game Technologies: DirectX, XNA, XACT, etc. GameComponents class inheritance

  Hi, Right now, when you add a GameComponent to your project, it inherits from the class GameComponent in Microsoft.Xna.Framework. In project that is fairly small or for giving components to other peoples, it works great. But I see a problem when you want to build components for a large scale engine. Let's take a Grid GameComponent as an exemple. This game component cannot inherits from any of the class that already exist in my engine simply because C# does not allow multiple inheritance. So, I cannot give the grid any of my scene graph functionality since that functionality is not built in inside GameComponent. I could use an interface to implement this but then I'll have to add the same code to every component. ...Show All

• Visual Studio Express Editions FontStyle

  Here is what I am using Dim font_style As FontStyle = FontStyle.Regular and here is the errorr that I am getting Font 'Monotype Corsiva' does not support style 'Regular'. My question is how do I tell the program to load the font in it's default style Tricky problem. There is no way to find out what styles a font supports, other than by trying them all until you don't get an exception. Of course, it is quite unusual for a font not to support the Regular style. Try something like this: Public Shared Function CreateWeirdoMonoTypeFont(ByVal family As String, ByVal emsize As Single) As Font Dim styles() As FontStyle = {FontStyle.Regular, FontStyle.Italic, FontStyle.Bold} For Each style As FontS ...Show All

• Visual C++ PrintTo command in the ShellExecute

  Hello, I'm trying to use the ShellExecute API to print an HTML file to a specified printer passing the "printto" as the command verb. My default Internet Explorer is IE 7.0 Beta (I tried this also on IE 6), the problem that also I use the PrintTo verb and I pass the printer name to the ShellExecute, the Print Dialog of the IE. Is this a bug in IE Please give me a hand. Your question is actually off-topic as this forum relates to C++ language issues.

• Visual Studio 2008 (Pre-release) svcutil and IDictionary

  I use the /ct option on svcutil to specify the collection types I want it to use for lists and dictionaries: /ct:System.Collections.Generic.IList`1 /ct:System.Collections.Generic.IDictionary`2 The first one works - it generates all generic list types using IList<T>. But the second one does not work. It still uses Dictionary<K, T> instead of the interface I specified. Is this a known problem or am I missing something Thanks... Hi, ReyCri, thanks for the follow up. Apparently I was reproing your problem different with the way you used it. Because I didn't see your contract, so I tried to repro it for datacontract so I used commandline option /dconly and /ct, in this case, the svcutil generated something li ...Show All

• Visual Basic Lock on DB

  Hi, I have developed a VB.NET windows based application and am using SQL 2000. After using this application for a while then it becaomes slow.I found out that it is because I use select statements and readers and these cause a LOCK on the DB so that the correct data is always displayed..... How do I use select statements and readers so that they do not cause a LOCK Thank You, There are a variety of lock options for SQL server. These are included in the SQL statement. The one you are talking about is NOLOCK The following article details some of the others. http://www.sql-server-performance.com/rd_table_hints.asp I would however say that unless you really see the default locking as causing problems then dont change ...Show All

• Visual C# Saving from a RichTextBox control in the selected TabPage

  I have a text editor program I am making, where a new tab page is added to a tab control every time the user clicks a specific button.

• Visual Studio 2008 (Pre-release) Is this the expected behavior ? (Animations)

  I'm trying hard to use animations in my application. Along the way, I felt many pains, some of them being: Let's put 2 animations in a storyboard: <Storyboard> <DoubleAnimation ... Completed="DoneHandler" BeginTime="0:0:0" Duration="0:0:1" /> <DoubleAnimation ... BeginTime="0:0:1" Duration="0:0:01" /> </Storyboard> Do you think it's normal that the Completed handler is called after the whole storyboard is completed, not when the first animation completes Is it normal that if I put the same code as above into the Resources section of a template, the Completed handler isn't called anymore at all, and no error is raised It would be awesome to be able to do some a ...Show All

• Visual C++ How can i make my editing auto completed?

  I use vs2005 to write cpp code A class is defined in a .h file, and I refer to this class in a cpp file including the .h. when I type "->" following a pointer of that class, no hint is showed about the members How can I make it work, thanks Then you should put define blocks around it. //a.h #ifndef __A_H__ #define __A_H__ class a { //whatever is in a }; //b.h #ifndef __A_H__ class a; #endif class b { /whatever is in b } By doing this you will have it only resolving the decleration when there is no previous inclusions of a. Or another step in this could be. #ifndef __A_H__ #include "a.h" #endif So you can include the entire class decleration when no previous include for a.h exists. ...Show All
