• SQL Server using GUID / uniqueidentifier as primary key

  <BACKGROUND INFO> We are in the database design stage of creating a db and we plan to use a GUID as the primary key for our tables (the app will be a smart client and will need to support offline functionality so when the app comes back online and the queued up inserts come thru we want to ensure that the primary keys are unique). We plan to have the app generate the guid and to send the GUID over as a parameter i.e. <code>GUID myPrimaryKey = GUID.NewID(); </code> and will not be using the DEFAULT NEWID clause on the CREATE TABLE statements. </BACKGROUND INFO> <QUESTION > Is it better to make the data type for the primary key columns to be uniqueidentifier or should the datatype be varchar(36).</QUESTION ...Show All

• Visual C++ How do you make a single file compile without making a whole project in vc++ 2005?

• Visual C++ Why doesn't PDH work?

  Hello, I've been trying to develop an application that reads the CPU load from the computer and the free RAM memory available. To do so, I was primarily thinking about using the PDH interface, since we are building to Windows Server 2003 and Windows XP, both of which already come with the PDH.dll. I downloaded the platform SDK from Microsoft's site, and I am using Visual Studio 2005. My dilemma is, every time I try to compile the source code, it gives me several errors, even with example codes taken from Microsoft's site. It gives me several unindentified objects in _main (it cannot understand/localize the commands, datatypes and so on). I don't understand why. I tried copying the pdh.h and pdh.lib to the main i ...Show All

• Visual Studio 2008 (Pre-release) Binding DateTime - formatting issue

  I'm working on a Windows machine which has got CurrentCulture set to "en-AU" but CurrentUICulture set to "en-US" This is causing binding to flip dates around such that 7/2/2007 becomes 2/7/2007 - not good! I've tried setting the CurrentUICulture to CurrentCulture but am guessing that a separate thread is displaying the xaml as the binding still fails. One option is to attribute xml:lang, or the Language dependency property, but this would cause US users to see an Australian date format for example. Is there a way to set the CurrentUICulture to the CurrentCulture so that WPF sees the change And on a side issue, why would the two cultures be different Thanks in advance, Graeme The only ...Show All

• Visual Studio 2008 (Pre-release) Flow Custom Principal with WCF

  Hi, I'm using a custom implementation of IPrincipal and I'd like to flow it from the client to the service, how is this done in wcf. In .net remoting I've used a custom sink to take the principal from the thread on the message an on the service back to the thread. Thanks, Markus You can add additional information in headers and send them to the server. It would be better to be able to recreate the custom Principal in the service based on authentication. Otherwise you would trust the client to provide security information - which would extend the trusted subsystem to the client. Technically - you can create a custom Principal on the server by using the "custom" PrincipalPermission ...Show All
