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

I keep getting the error message below when attempting to import a text file (flat file) to an SQL Server Destination using SSIS. 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!!!

.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?

Visual Studio 2010 Creating Executables On Multiple OS social.msdn.microsoft.com

I am converting an older software package written in VB 6 to VS 2010.Not to incredibly painful but planning for the future as we have had lets say a few issues with VB 6 on our current layout of multiple OS and this is my first real project lead.We are a smaller job shop and we move on a rotation of new PC's/OS's come in to replace broken or exhausted older PC's in the front office and move the older PC's out to the shop floor.We have an array of different OS's ranging from Windows 98 and Windows 7 (32 bit and 64 bit OS). By the time I am done with the conversion we should be sitting comfortable with a range of PC's from XP and up. When creating the executable for my project is this something that can be handled ahead of time, creating multiple executables for specified OS, or an all in one package executable?I was looking to see what people had as suggestions at handling this.We haven't even bought VS yet and are looking at the VS 2010 Premium package, do I need Ultimate?
