• Game Technologies: DirectX, XNA, XACT, etc. Xbox 360 Project to Windows Project

  I was wondering if there is a easy way to recompile an Xbox 360 project to a Windows project, because I can't always be connected to my xbox to test out what i'm working on since the xbox is shared by the family. So can I make a change to my program an recompile it for windows so I can see if my change worked and once i'm done making changes to the program I can then build it for the xbox and try it out. Thanks That approach kind of works, but there are some gotchas that might trip you up (which is why we didn't do this by default). Stephen wrote a post explaining the issues that can come up with this. ...Show All

• SQL Server How to do QTD and MTD in MDX ?

• Game Technologies: DirectX, XNA, XACT, etc. End users shouldn't have to rewrite XNA math functions in order to improve performance.

  The overhead of passing a 64 byte Matrix by value is significant. Most especially when you are comparing two matrices for equivalency (==), or performing a Vector*Matrix multiplication (Vector3.Transform(Matrix)). The following matrix comparison function performs 5-10 times better than your built in == comparison. If the matrices are equal, then it is about 5 times faster. If they are unequal then it fails fast, and is about 10 times faster. public static bool Equals(ref Matrix a, ref Matrix b) { // i check the diagonal first for quick fails return a.M11 == b.M11 && a.M22 == b.M22 && a.M33 == b.M33 && a.M44 == b.M44 && a.M12 == b.M12 && a.M13 == b.M13 && a.M1 ...Show All

• SQL Server SSIS Performance Issue

  Hello, I have been running massive ssis packages and testing the performance. This is my execution design: I have a main package that gets a list of packages to execute from a table. Then using a foreach loop in send the package to execute ( somewhere in the middle i delete the corresponding old log file for that package ), each of the packages configures themselves from the parent package variables. What i have been analysing tells me that for example a package runs in 2 minutes and then the time wasted from the end of the package to the start of the other task is in average 3 to 6 minutes... thats alot... since i run about 20x12 packages witch gives me of wasted time about 20 hours. My question is... what can be causing ...Show All

• Windows Forms ComboBox and TextChanged again (or still)

  Hi, I see a couple of posts around this topic but oddly, not this exact question, at least not with an answer. I created two projects, both Windows Application, one in VB 2005, one in C#. I have .NET 2.0 installed. Each project consists of a form with a single ComboBox, and the DropDownStyle of the ComboBox is DropDown. I need to be able to catch both changes to the selection in the list or keyboard edits in the box. In both programs, I add an item to the drop down list when I load the form. Then, I try selecting and then editing. In VB, selecting the item first fires the ComboBox1_TextChanged sub and then the ComboBox1_SelectedIndexChanged sub. Editing fires only the ComboBox1_TextChanged. This is fine. In C#, however, selecti ...Show All

• Software Development for Windows Vista Do unsigned apps always give a UAC warning?

  We're distributing a legacy app. Do all unsigned apps in Program Files cause the UAC warning when run Is there any reason we can't just have the user install the app in C:\users\login-name so that we avoid all the UAC problems of Program Files We have the similar problem, but our package is not MSI-one. I suppose the reason covers in the type of the installation package - at present we have simple EXE-file generated by IS, but soon we'll migrate to MSI packages due to LOGO certification (this is a requirement). I'd be glad if someone could clarify if I'm right or not, but if no one can I'll inform this Forum's inhabitants as soon as I get the answer by myself. :) By the way, does anybody know why Vista marks executable files with ...Show All

• SQL Server Help! Create index with substring

  Good day! We had decided to migrate from Oracle to SQL Server, so faced some problems. Using Oracle we could create indexes like that create index obj_id_cnum on obj_id (substr(cnum,1,2)) But Microsoft SQL Server doesn't allow this code. How can we do the same using SQL Server. Thanks you. Is obj_id a table, I am assuming If so, then you are right, you cannot apply an index on a function directly. Two ways you can approach this: 1. If using enterprise edition, you can index a view and it will be used: create view obj_id_indexed as select obj_id_key, cnum, substring(cnum,1,2) as cnumSub, from obj_id create unique clustered index on obj_id_cnum(obj_id_key, cnumSub) Now your qu ...Show All

• Windows Forms Problem Publishing to the Web

  After completing my application I used VB 2005 to "Publish" to the web and supplied a website address. After the publish I copied the published files to the correct directory on my website but whenever folks access the publish.htm page all they get on their screen is a dump of XML code.

I want to learn the basics and the advanced of direct X, from the ground up NOT from the perspective of making games.
