Cannot Convert Between Unicode And Non-unicode social.msdn.microsoft.com

This database has recently been migrated from SQL Server 2000 (where I used a DTS Package that worked fine). I plan on doing further manipulation to the file after importing but have so far tried to keep one step at a time. I have tried using a smaller files and different tables but still get a similar response. I believe that the encoding of the text file is ANSI. If it is relevant the database collation is Latin1_General_CI_AS (the same as it was when 2000). Any help anyone can provide will be greatly appreciated!!!

Conversion From Type 'String' To Type 'String' Is Not Valid stackoverflow.com

I'm in the process of porting an old excel addin that was writen in VBA to VB .NET. The Excel addin interacts with a number of external com objects. The code sorta looks like this:[code...] What I'm trying to do is read the string from the COM object and get it in durr for use later in my program. That second line results in the exception posted above. If I try casting with CStr/CType I get the same exception. The visual studio watch window reports the type of hurr.getString as a "System.__ComObject" whereas the VBA watch window reports the type as "Variant/Object/String". Microsoft.VisualBasic.Information.TypeName(hurr.getString) says the type is "String".

.net - Have Double->float Conversion Regarded As "widening"? stackoverflow.com

Is there any way to tell vb.net (2010) to allow expressions of type Double to be passed to parameters expecting Float, without having to use an explicit CSng() calls, other than by turning off all complaints related to narrowing conversions? Given that a Double->Single conversion will never throw an exception, and given that precision loss does not seem to be a criterion for regarding a conversion as "Narrowing" (Long->Double is considered "Widening" despite the fact that it involves an inexact conversion from an "exact-value" type to an "approximate-value" type; a Double->Single conversion merely goes from an "approximate-value" type to a "somewhat-more-approximate-value" type, so it is in some sense less lossy).I know turning off Option Strict would eliminate squawks about Double->Single conversion, but that is incredibly massively overkill. Is there any way to stifle all complaints about Double->Single, without stifling other possibly-useful squawks? Edit:If Microsoft isn't going to allow code to be written in the most logical fashion, would it be preferable to litter the code with CSng() every time I call graphics methods, or define NewRectF and NewPointF methods which accept doubles and then use the RectF/PointF overloads for the graphics methods?
