Q: How can I create a unique value without using a counter?
A: The .Net framework provides a method for generating a universally unique identifier or GUID and can be accessed as shown below:
Dim strGUID as String = System.GUID.NewGuid().ToString()
GUID is short for Globaly Unique Identifier. This number is
based on IP address, MAC address, and date/time. It's represented as a series of alpha-numeric characters in the format {8-4-4-4-12}.
Using the NewGuid() method allows unique numbers to be generated by one function call, without concern for repeating identifiers or counters.

C# in SQL Server 2005 Reporting Services
Q: I know that VB.Net functions are available in SQL Server 2005 RS (Reporting Services), but does it also accept C# commands?
A: The expression language for Reporting Services is VB.Net only. You can call an assembly that contains functions written in C#. This is a very valid option, but the call from within the report will be with the VB.Net syntax.
Thanks to Mike Shelton (Microsoft) for answering this question.

MS Certification Courses
Q: Where can I take a class that would be geared toward certification in either .NET forms or ASP.Net? I interested in exams 70-315 or 70-316.
A: Check out this link (http://www.microsoft.com/learning/mcp/mcsd/requirementsdotnet.asp). It lists the tests needed for passing the MCSD along with MS courses. You can register with these exact same course numbers at CCC or CSU Continuing Education, or any other MS certified training facility.
Also, right now MS is offering a free second shot exam if you register before end of June. For more info, see http://www.microsoft.com/learning/mcp/offers/2ndchance/.

Microsoft Downloads
I found a few interesting downloads, free from Micorsoft.
User Profile Hive Cleanup Service:The User Profile Hive Cleanup service helps to ensure user sessions are completely terminated when a user logs off. System processes and applications occasionally maintain connections to registry keys in the user profile after a user logs off. In those cases the user session is prevented from completely ending. This can result in problems when using Roaming User Profiles in a server environment or when using locked profiles as implemented through the Shared Computer Toolkit for Windows XP.http://www.microsoft.com/downloads/details.aspx?familyid=1B286E6D-8912-4E18-B570-42470E2F3582&displaylang=en
Port Reporter:Port Reporter logs TCP and UDP port activity on a local Windows system. Port Reporter is a small application that runs as a service on Windows 2000, Windows XP, and Windows Server 2003. http://www.microsoft.com/downloads/details.aspx?FamilyID=69BA779B-BAE9-4243-B9D6-63E62B4BCD2E&displayLang=en

Microsoft Anti-Cross Site Scripting Library
Microsoft has recently released an Anti-Cross Site Scripting Library to help prevent cross site scripting attacks. To download the Anti-Cross Site Scripting Library, go to http://www.microsoft.com/downloads/details.aspx?familyid=9A2B9C92-7AD9-496C-9A89-AF08DE2E5982&displaylang=en
A Cross Site Scripting attack (XSS) occurs when a hacker inserts a link in an e-mail or web forum that appears to be legitimate (i.e. cnn.com, google.com). However, the link actually a malicious script code embedded in the URL. When the unsuspecting user clicks the link, the script is executed on the host web site. The script code maybe used to transfer cookies from the victim's PC to the hacker's machine. The cookies may contain user ID's, passwords, or possibly credit card information, all which can be used for illegal purposes. To read more about this security attack, visit http://msdn.microsoft.com/library/default.asp?url=/workshop/author/dhtml/httponly_cookies.asp

What is the difference between classes and modules?
Q: What is the difference between classes and modules?
A: Visual Studio.Net stores code in either classes or modules. Classes are used for items that define their own storage and have persistent data. In addition classes must be instantiated before they're used, unless the keywords "Static" (C#) or "Shared" (VB.Net) are used.
Modules, on the other hand, can be viewed as simple code libraries where the methods can be called directly.
