• SQL Server distinct count with multiple partitions?

  We analyze much of our data using distinct measures. Some of the underlying sources - i.e. daily page views are heavy and have millions of rows a day. Because of this I've created daily partitions to only process the incremental data that's arrived. However, I'm curious - how does distinct count perform when it needs to rollup over multiple partitions IE Say it's Dec 25th, and I have 25 unique partitions for each day of December thus far. Internally, how do the distinct measures correctly accumulate the unique instances of my measure Are there any significant performance concerns to be aware of Distinct Count measure will work fine with multiple partitions. AS keeps the distinct count values inside the ...Show All

• Windows Forms click once? or maybe not

  Hey guys, please someone help, here goes: program all created and deployed using the built in installer. But heres the problem: It installs off the website on my mates computer and mine, but some other pc's running xp, when i click on install from my website displays the xml document code instead of installing the product, obviously this kinda install process is not all that good if it only works on a certain percentage of computers, the only thing I can think of this is that a certain client has not certain updates installed on there pc, but still this is not handy situation for me, Then I thought ahh could be because they dont have .Net framework 2.0 installed, But that wasn't the case either. Is there a way of sorting this or s ...Show All

• Windows Forms Adware?

  Whenever I publish a program (VB2005), my browser (FF) comes up with the file location: C:\Documents. It also brings up AND.com and Settings.com web page. My question for you is... is this related anyway to VS2005 Or is it something more sinister Thanks. THis is not OFF topic. This is related to and/or cause by VBN because it only happen whenver I publish a program. I understand, its unfortunate it happens with one or the other and it is a known issue I believe but not relating to ClickOnce or VB.NET but rather the toolbar or the web browser. Something just triggers it, which is silly for the web browser to pick up on it. have you tried it on a different machine just to see what happen ...Show All

• Visual Basic Fixed Width Text File Into SQL Database

  Any ideas on how to import a fixed width text file into an SQL database Write a conversion application which reads the values in from the text file. I'd suggest looking at the textfieldparser class http://msdn2.microsoft.com/en-us/library/zezabash(VS.80).aspx Then you can use ADO.NET to execute a Insert SQL Statement using the values read in from the text file. The following shows how a simple ADO.NET command object can be used to execute a SQL Insert Command http://samples.gotdotnet.com/quickstart/howto/doc/adoplus/ExecuteCommand.aspx Thats just the general idea of how to implement a solution.      Basically its breaking it down into two actions reading a line from the text file and updatin ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Normal Map colour directions.

  Hey, I've been tyring to track down a couple problems I've been having with rendering normal maps. First of all, I have these shaders that I have programmed previously that take a tangent space normal map and function 100% correctly. If I move those shaders and normal maps onto an object in Game Studio I find a number of issues. The normals in the normals map seem to receive the light from the wrong directions, the flat surface areas are lit correctly though. So I was wondering if which directions the normal map need to be, Red left or right, Green up or down. I've tried a number of different arrangements and orderings of my Normal, Binormal and Tangent matrix. The second problem is I find that the Binormal and Tangent data changes d ...Show All

• Windows Forms Can I generate a managed resource DLL at run time?

  Reading through the .NET 2.0 documentation, I get the feeling that the answer is yes, but I can't find the steps I need. I am developing for Windows Mobile, and have a need to provide two different types of multi-lingual support. One is typical translation from English into other languages, which I can cope with quite easily using all the design time features of VS 2005. The other kind of support I need is not so much for the language in use, but rather the terminology. The system I am developing 'plugs in' to several different packages, and we would like the screens on our mobile application to use terms that match the clients' existing back-end systems. For example, what one product calls an 'Account', another will call a 'Clien ...Show All
