• Game Technologies: DirectX, XNA, XACT, etc. DirectX to differentiate between audio and video files

  Hi, I wanted to know if DirectX could be used to identify a media file as Audio/Video. Audio includes all the common formats in use and so does video. Basically, I would like to know if DirectX could be made use of to classify a media file as audio or video. Thanks, Raichur. Have looked at AudioVideoPlayback library. MSDN doesn't give exhaustive information about it. ...Show All

• SQL Server Insert & Where ?!

  Hello everyone, im looking for some advice or maybe examples. How is the best method of checking a table for a specific xmldata type node element For example xmlNode = Table in use myXmlData = Document being stored as XML datatype I would like to first check the table of existing XML entrys for an ip address: If the ip address in the reader matches any of the ones in the database it will update that row.

At the moment data is stored regardless of existing entrys. myQuery = "INSERT INTO T4(xmlNode) VALUES(@ ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Code behaves differently on 3 different computers. ???

  I have a C# application that displays fairly simple 3d models (mostly lines and a few faces).  I am using Managed DirectX 9 August 2005.   On one computer (the development machine) the program runs fine.  On another computer, the lines don't draw (it's a call to drawIndexedPrimitives, type lineList) but the meshes do draw...and on two other computers, when I open the Form that has the 3d control, the computer freezes (before the form ever opens) and must be shutdown with the power switch.  I know this is a question with not much detail...but I'm not sure how much detail is needed to be helpful.    It's ...Show All

• SQL Server OLE DB Command with property expression

  Hi, I am trying to use an OLE DB Command to run a different SQL command for each row in the data flow. I have a script component that builds the SQL command and puts it in a data flow variable, and a property expression in the data flow mapping [OLE DB Command].[Sql Command] to that variable. The problem is that the OLE DB Command has a validation error, saying that "the command text was not set for the command object", and it doesn't run. Did I miss anything should I tell the OLE DB Command that the SQL command would come from expression or is it a bug Thanks. This validation error ca ...Show All

• SQL Server Error when attempting to delete rows

  I have a log table with no indexes, triggers, or keys.  During the course of development, I will clean out the entries by selecting all the rows (in Database Explorer) and hitting the delete key. Occassionally, I will end up with couple rows (out of many) that won't delete.  I get the following error when I attempt to delete the "affected" rows:    A problem occurred attempting to delete row 1.    Error Source: Microosft.VisualStudio.DataTools.    Error Message: The row value(s) updated or deleted either do not make the    unique or they alter multiple rows (2 rows). ...Show All

• SQL Server Looking for sample code for doing store procedures

  I'm looking for any good samples that anyone might be aware of on how to write a SQL Server 2005 stored procedure with error handling (using TRY-CATCH blocks) that I can use as a model. I did find the article "Detecting and Reporting Errors in Stored Procedures - Part 2: SQL Server 2005 TRY-CATCH Blocks" by Rob Garrison.  It's pretty good.  The article was written based upon an early beta so the author (understandable) wasn't sure about some possible features.  I also was disappointed that the examples didn't flow back to showing how the application handle the resulting errors. If you know of any good article or samp ...Show All

• Visual C# Nice Threads!

  I could really use some help here... I am using C# 2005 and have created a splash screen that runs on a seperate thread. I can invoke the splash screen in the Main() method, but then I can't get rid of it! I am attempting to put a line in the Form1_Load (or maybe Form1_Shown) that calls a static method in the splash screen to close that form. But, when I do so, it complains about an invalid cross-thread operation. How can I get this screen to close Here are the relevant parts to my splash screen: // Static Public Method to launch Splash Screen static public void ShowSplash() { if (ms_frmSplash != null) return; ms_Thread = new Thread ...Show All

• Windows Forms Owner Draw ContextMenu

  Hello everybody, I have a problem. I can create owner draw menu but only MainMenu. Contextmenu doesn't want to be created. Can anybody write sample of it Sorry for my bad English. I believe you have to set the OwnerDraw property of each menu item to True. Then what I usually do is create one sub to handle all of the items for example: Private Sub MeasureMenuItem( ByVal sender As Object , ByVal e As MeasureItemEventArgs) Handles menuItem1.MeasureItem, menuItem2.MeasureItem         Dim mnuItem As MenuItem = DirectCast (sender, MenuItem)       ...Show All

• Visual Studio Team System VSTS Ship Date?

  VS 2005, SQL 2005 and .NET 2.0 are supposed to release in early November, however on the FTP web site they are saying this: Updates and firm release dates for Visual Studio 2005 and .NET Framework 2.0 (together previously code-named "Whidbey"), along with SQL Server 2005 (previously code-named "Yukon"). The target release dates are well within Microsoft's most recently stated goal (second half 2005), although some of the features expected in the first release of Visual Studio 2005 won't be immediately available (the full Team System tool set, specifically).   http://www.ftponline.com/channels/net/reports/tech-ed/2005/okelly/   S ...Show All
