Audio and Video Development Can XPath variables be used in <styling>
I wonder if the xpath variables can be used like : style:x="$style_x" in <styling> in .xmu , and style_x is from document.setXPathVariable("style_x","200px"); in .js . I know the xpath variable can be used in <timing> and <body>. Anybody can help me Thanks in advance. HI there Xpath variables are meant to be used only inside Xpath Expressions (that's why they are called Xpath Variables :) ). I guess at least pre-defined Xpath variables can be used in XMU (inside Xpath Expressions). Author can define her own Xpath Variables in a js file.I am not sure whether author-defined variables can be used in XMU ( inside Xpath Expressions). ...Show All

.NET Development Serialization?
Can someone give me a slightly "dumbed-down" explanation and example of serialization Where might one use serialization when developing well serialization is a way you can store a collection of objects into an Xml format then reconstruct them again either at say, load time of an application or perhaps stream it down the wire (network communication) Take a look at this: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=590301&SiteID=1 http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=724142&SiteID=1 http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=837396&SiteID=1 basically you can think of it as a way of storing data into an xml format which late ...Show All
Game Technologies: DirectX, XNA, XACT, etc. Only 32 primitives drawing correctly.
I've made a program that draws multiple triangles on the x-z plane. My eventual goal is a hight map but I'm having a problem with the DrawUserPrimitives call. It works fine if I set the number of primitives to draw up to a maximum of 32, but any greater number and I get some very strange random triangles all on top of one another. I looked through the API and found that there was a MaxPrimitiveCount method but that returns 1048575 so I don't think thats a problem. All the values in my array seem fine, if I copy the end triangles to the beginning of the array they display fine (until 33). If I put the loop that fills the array in my draw method and draw one primitive at a time (by just writing to position 0, 1 and 2 of the array) it works ...Show All

Hi again, this time i need some major help. I'm creating a shooter arcade, and the biggest problem i ran into so far was getting the sprite to fire towards my mouse positioned reticule. Could I please get some information on how to tell the game code that i want the sprite to move towards the mouse x,y from it's fixed positions. Thx for your help. What you are describing is Bresenham's algorithm. Check out this article: http://en.wikipedia.org/wiki/Bresenham's_line_algorithm You'll have to do a little work by reading the article, maybe even a few times over to get the idea of it but it describes exactly how to do what you want.

SQL Server Is it reasonable that a table has 240 fields
Hi, I have 240 sensors to sample one time per second,then store the data in sql server. Is it reasonable that the table has 240 fields If do,it will generate about 70,000 records every day.One month records will be 2,100,000. If I divide the 240 sampling data into 10 records,every record has 24 fields.Then every day 700,000 records will generate.One month the record number is 21,000,000.It is terrible. Which method is better,or who can give me another better method or some suggestions. I need your help.Thank a lot. Yes,most of fields should be filled. I store these records just for query history records and display every sensor's line. But I have heard that many fields will lead the database system low efficiency ...Show All
Visual Studio add costum MSHelp:Attrib to Sandcastle generated hxS content...
Hi all, is there a possibility to add costum "MSHelp:Attrib"'s to Sandcastle generated HxS content The main reason, I want to do this, is to generate a costum filter, to display only sandcastle generated help topics after integration into vs studio help.

Visual FoxPro Report strategy
Hi everyone; I am going to develop quite a few reports for a customer. They want to develop a report engine that would let them customize reports both in the scope and in the format of the report. I am wondering if I should use a third party product like CR. Can someone give me some pointers ergarding the benefits of using CR or other reporting engine, and also how difficult is it to incorporate such reports into my application, and letting users customize reports Thanks. You can do both within VFP. Scope: just add a form to let the user choose the scope and create the cursors before running the report. Format: exclude the reports from the exe in the project, include them in a folder ...Show All

Visual Basic Shared property works in VS2003, does not in VS2005
I'm moving an asp.net program made in Visual Studio 2003 over to VS2005. I'm just creating the pages in VS2005 and copying & pasting code. I'm finding my Shared variables are not working in VS2005, as I get the error "Name 'Errors' is not declared". In the example below, I have the Class "Errors" (a web page, "Errors.aspx") which sets the property. Then I show the Sub addFootnoteToPDF() which is on another page (open.aspx); this makes a reference to the property in Errors.aspx. Can you see why this works in VS2003 and not in VS2005 Thank you!
