Quirks of LEN
As we all know, the LEN function in T-SQL returns the character length and at that ignores the trailing blanks... So, how to return the length including these trailing blanks? I experimented a little and found that all you have to do is CAST to the appropriate MAXed variant of your datatype. So just try the following:
DECLARE @l_nContentMax NVARCHAR(MAX)
, @l_nContent NVARCHAR(20)
SELECT @l_nContentMax = '1234567890 ' -- character length = 15
, @l_nContent = '1234567890 ' -- character length = 15
SELECT LEN(N'1234567890 ') AS Plain
, LEN(CAST(N'1234567890 ' AS NVARCHAR(MAX))) AS MaxCast
, LEN(@l_nContent) AS PlainVariable
, LEN(@l_nContentMax) AS MaxVariable
This results in:
So... just cast your expression to NVARCHAR(MAX) or VARCHAR(MAX) where appropriate and you'll get the right length
DECLARE @l_nContentMax NVARCHAR(MAX)
, @l_nContent NVARCHAR(20)
SELECT @l_nContentMax = '1234567890 ' -- character length = 15
, @l_nContent = '1234567890 ' -- character length = 15
SELECT LEN(N'1234567890 ') AS Plain
, LEN(CAST(N'1234567890 ' AS NVARCHAR(MAX))) AS MaxCast
, LEN(@l_nContent) AS PlainVariable
, LEN(@l_nContentMax) AS MaxVariable
So... just cast your expression to NVARCHAR(MAX) or VARCHAR(MAX) where appropriate and you'll get the right length

Unable to connect to this Team Foundation Server...
Microsoft Visual Studio 2005 pops up a nice dialog with three possible reasons for failure:
Well, apparently the appSettings node must be located below the configSections node. If not, all kind of strange things (like not being able to connect to TFS) will occur.
