• SQL Server Dialog Security and Message Encryption

  I understand that Dialog Security + certificates can be used to encryption individual dialogs. I have several demos working now that do just this.However, I don't fully understand exactly when the messages are encrypted, and if they are ever written to a queue on the initiating service prior to being encrypted. I want to make sure that admins can't simply query the transmission queues to get clear text messages, because I have strict requiremen ...Show All

• Visual Studio Team System No Discussion Lists Web Part on Project Portal?

  I'm still learning Windows SharePoint Services in order to understand TFS Project Portals. I noticed that the project portal created with MSF Agile template does not allow one to create Discussion Lists or Surveys. Yet, I can go through the SharePoint Central Administrative site and create a site off a different template that can have Discussion Lists. What do I need to do to have Discussion Lists on my TFS Project Portal Thanks, Zoiner ...Show All

• SQL Server Using ALTER ASSEMBLY to refresh the bits of an existing assembly

  According to the documentation , it looks that it's possible to use ALTER ASSEMBLY to change the contents of an existing assembly: "If the FROM clause is specified, ALTER ASSEMBLY refreshes the assembly with respect to the latest copies of the modules located at the network location you specify." However, if I execute: CREATE ASSEMBLY [MyAssembly] FROM '\\mymachine\Test\MyAssembly.dll' ALTER ASSEMBLY [MyAssembly] FROM '\\mymachine\ ...Show All

• Windows Forms datagridview bit column - display something other than True/False?

  Can I get a bound datagridview to display something other than True or False for a bit column eg Yes/No or Correct/Incorrect No, the Boolean column only shows the checkbox, not true/false. If you have a database and you have Correct/Incorrect in a record you can show a check for Correct and a uncheck for Incorrect. To do this set the TrueValue and FalseValue properties to the string values. Hope this h ...Show All

• .NET Development Checking if I'm online

  Hello there! This is my 1st post here and I'd like to greet all people here and ones that are yet to come! I hope we will cooperate just fine. For start, I have a question: I'm making a project with Visual Studio .NET. It is a counter that counts time spent online. (most people in Croatia still use dial-up networking, including me) I'm doing the code in C++. I was wondering how can I check if I have connected to Internet. Another think (I thi ...Show All

• Visual Studio 2008 (Pre-release) Pixel width "Thickness" for shapes

  Is it possible to draw shapes with a single pixel width I am working on an engineering program in WPF and need to scale drawings. The current thickness of 1 is more than one pixel (presumably anti-aliased) and is very "fuzzy" - that's an engineering term! The same drawing drawn with GDI looks much crisper - another engineering term. Ideally there would be a special thickness, say 0, which would always draw at one pixel width no m ...Show All

• Visual Studio Team System Unlock bug ?? TF10152 The Item <> must remain locked ...

  I did a recursive lock of an entire source (yikes that took so long I killed the console window).  In order to unlock everything I did the same thing again except that I used the /lock:none switch.  But I get a bunch of errors like these: TF10152: The item $/TestCmmiTemplate/Trunk/WWW/default.gif must remain locked because its file type prevents multiple check-outs. Now we added GIF as a file type that doesn't allow multiple check ...Show All

• Visual Studio Team System VSTS integration with MS Project 2000

  Hi, It seems that TS ships plugins to integrate Project 2003 with TS. I have Project 2000 installed. Are there plugins available to integrate TS with Project 2000 too or am I missing something... Thanks, Deepesh Hi Deepesh, From my experience and everything I've read, Project 2003 is required.  I believe it has to do with extensibility options (e.g., .NET) that weren't avaliable in 2000.  I tried it once, it didn't work, and ...Show All
