Visual Studio Team System install prompting for login
So, after having nothing but problems with installing a Dual Server setup, I decided to take the easy way out and try a Single Server setup. As luck would have it, Single Server is turning out to be just as big a pain as the Dual Server install. Towards the end of the Team Foundation Server install, I'm being prompted for login credentials. The title of the box is "Log on" and the text above the User Name says "Connecting to Team Foundatio ...Show All
.NET Development Increasing the runtime heap?
Hi I've got an issue with OutOfMemory exceptions occuring in an application. I know the gen 0 heap size is based on the L2 cache of the CPU running the system, but even when I try to run my process on a system that has a megabyte of it, it gets the exception not even halfway in. Normally, I'd just take it for granted that I was wasting too much memory too quickly, but the problem is - I need all of the memory I'm trying to allocate, and I nee ...Show All
Game Technologies: DirectX, XNA, XACT, etc. I need some spiritual DirectX guidance.
I've been learning from a book titled Tricks of the Windows Game Programming Gurus by Andre' Lamothe.

SQL Server fn:contains() and full-text index
I am glad to find out that full text index on xml column is actually xml aware - that I can use xquery to perform the search. However, when trying to find a word or phrase inside a node using contains(), it seems this function behaves differently in following situations: 1. contains(xmlCol, 'search text'), this works case-insensitive 2. contains('/root/someElement', 'search text'), this works case-sensitive In both cases, I have crea ...Show All
