SQL Server Large Sample Database required for testing
We are creating a search engine in MS SQL using FullText etc. we need to run some tests against a database that is near to realistic data. We have been able to generate a database of thousands of usernames, first names etc. but we can't figure out where to obtain a database full of data that contains product descriptions, product titles etc. Does anyone have any idea where we could obtain (or even buy if need be) a large database (over 10,000 records) of sample data that we could run test queries against, so that we can optimise the queries, provide execution time estimates etc. We have downloaded the adventureworks sample database, but there are not nearly enough records in it. Any help would be much appreciated. ...Show All
Game Technologies: DirectX, XNA, XACT, etc. Determining if (part of) traingle passed depth buffer test/got rendered
My problem is simple, I want to draw an triangle (or anything for that matter) and then want to know, in the fastest possible way, if anything actually got rendered. I want to use this for a kind of portal engine. Basicly I want to draw part of a complex scene, with depth buffer enabled for read/write. Then I want to draw an transparent triangle (with depth buffer writing disabled), if part of this triangle is actually rendered (thus is within the viewing frustum and passes depth buffer test) I want to know this, so I know that which is behind it, is also visible. I need to do this several times per frame and want to keep my framerate up, so I want to do this as fast as possible. Does anybody has an idea how to do this ...Show All
Visual Studio Team System Error message when trying to do a merge
I'm getting the following error message when I am trying to merge from one branch to another. Error No matching items found in $/My/branch/path/here at the specified version. This occurs when I use the merge wizard. On the first page I choose my source branch, I choose selected changesets, and I choose my target branch from the drop down, and click next. On the second page I select the changesets I want to merge, and click next. On the third (and final) page It tells me that all necessary info was collected (among other things), and I click finish. After I click finish, that error message appears instantly. There is no delay like it is going out to the server, it just immediately pops up, I click okay, and the whole merge wi ...Show All
Visual Studio Crystal Reports VS.NET 2005 "Invalid Keycode"
I am creating a new ASP.NET web site and dropping a CrystalReportViewer on it in VS.NET 2005. I create a report source, I create a new report and when I choose ok, it tries to open the report to design it and I get an "Invalid Keycode" message. I found the information on the VS.NET 2002 and 2003 registry keys, but they don't exist in VS.NET 2005 of course, so that didn't help. I've gone through the repair option on the DVD, and verified that the Crystal Report section is all selected, but that hasn't helped. Does anyone know how to solve this provblem Thanks I guess the rule of thumb here is: when nothing makes sense, uninstall the piece, reboot and reinstall That corrected it for me. Now the key shows up ...Show All

Windows Forms Associate Data Source with CurrencyManager ??
Hi, is there a way to associate a Data Source with a CurrencyManager I'm facing a problem that I have a ComboBox from another table, and need to add the key in the master table.

Visual C# Changing Type during runtime
In response to my previous thread which can be read here , I've decided to create a new thread because although I mention this problem in my previous thread, this is a different subject. To recap, I have a class Shape, which will have many inherited types. In a class Physical, I have a Property which returns a Shape object. Many classes inherit from Physical, and each inherited class will need the capability of allowing the user to change the Shape Type during runtime. I came up with a decent solution, but was wondering if anybody knows, or can think of a better way(s) to solve this: [ BrowsableAttribute ( true ), ReadOnly ( false ), TypeConverter ( ty ...Show All
