• SQL Server Upgrading from Sql 2005 express to SQL 2005

  Hi, can anyone advise if it is possible to upgrade from sql 2005 express to SQL 2005 developer edition Thanks, Jimmy You won't be able to upgrade the software itself that way, but the databases from either automatically work with each other. Just back up one database and restore it on the other - no changes to the database or code is needed. Buck Woody ...Show All

• Visual C# Validation Philosophy

  I am working with a Winform in VS 2005. I have been reading some books lately that say that using the error provider and checking it when you save or exit a form is a better, (less intrusive) way of doing validation than putting up dialog boxes. I see the wisdom to it but I wonder what should happen when you have many records in a form That is, lets say I have a winform with the Standard menu and toolbar on it that VS creates automatically, but lets also say that this form (a detail form) has many rows. With regard to validation, how should it be handled Should I wait until save or exit is selected If so, telling the user that there a ...Show All

• Visual Studio 2008 (Pre-release) Type.GetMethod on method with complex signature

  I know this isn't directly pertaining to LINQ, but it pertains to something i'm devloping on top of LINQ. I'm trying to figure out how to use Type.GetMethod to retrieve a MethodInfo instance on the following method.  I've been at it for about 2 hours now, with no luck after trying seemingly all possible combinations of trials.  Can someone please shed some light on the answer, or possibly another direction to try public static Func<T, bool> Create<T, R>(CSExpressorOperator functionOperator, string propertyName, R value, R valueEnd, bool ignoreCase)  where R : IComparable<R>  where T : new() Note that ...Show All

• Visual C++ Build Warning PRJ0041

  When I try to build my solution from the command line, many of the projects throw the following warning: warning PRJ0041 : Cannot find missing dependency 'macwin32.h' for file 'project.rc'... I'm not doing anything which involves MAC code - as far as I can tell, this is the depencency system wandering through VC .h files and finding lines like: #ifdef _MAC #include <macwin32.h> #endif and ignoring the preprocessor condition (which is never TRUE in my case). The help for this warning gives a suggestion which is, frankly, unacceptable (create dummy files for the build system to find). Is there a better way to get rid of ...Show All

• SQL Server sql_variant and double.PositiveInfinity

  Hi All, With SQL Server 2000 it was possible store an infinite value in a sql_variant column. Since I upgraded to SQL Server 2005, I got following message: The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 4 ("@Actual"): The supplied value is not a valid instance of data type sql_variant. Check the source data for invalid values. An example of an invalid value is data of numeric type with scale greater than precision. What has changed between SQL Server 2000 and SQL server 2005 Is there any workaround   Thanks, Michael Th ...Show All

• Visual C++ Error missing runtime function in MSVCR80D.dll
