When using '+' to concatenate two string field in SQL server (e.g. a+b), if one of them is NULL, then the whole string will become NULL. There is one solution to solve it: COALESCE(a,'') + COALESCE(b,'') So if any of the field is NULL, it will evaluate as an empty string. That's it!

In case you just skip the post-installation messages... that may helps :P Configuring and Managing SQL Server Express ·    For improved manageability and security, SQL Server 2005 provides more control over the SQL Server surface area on your system.

From my experience, try to avoid turning on both AutoIncrement (in DataColumn) in .NET and Autonumber in MSAccess at the same time. As somehow there is just no communication between them. They just work on their own. For example, when you have records in ACCESS having ID (1,2,3,4) and suppose the next ID be 10 (as doing some record add and delete before). AutoIncrement in .NET just don't know about it as it's AutoIncrementSeed can just automatically set to 5. Then 10 vs 5, I hope you can see how the problem being occurred. So avoid having them both at the same time.

When working with .NET, you may wonder the difference between Literal and Label .

For those folks out there using Windows Server 2003 SP1 Build 1277 along with the SQL Server 2005 December CTP, you may be unable to install SQL Server 2005 with the following error: Microsoft SQL Server 2005 Beta 3 Setup The SQL Server System Configuration Checker cannot be executed due to WMI configuration on the machine SI4P64LF3-05 Error:2147749907 (0x80041013). The cause of this error is a corrupt install of WMI, caused by upgrading Windows Server 2003 to SP1 build 1277. To fix this issue, copy the following into notepad and save it with either a .cmd or .bat extension. Then run the script to re-install WMI: %SYSTEMDRIVE% CD %windir%\system32\wbem Mofcomp.exe cimwin32.mof Regsvr32 /s wbemupgd.dll Regsvr32 /s wbemsvc.dll wmiprvse /regserver If that doesn't work, try the info here posted on MSDN .
