Firebird ADO.NET Data provider for .NET and Mono ================================================ General. -------- - Char, varchar, decimal, date, time and timestamp Array fields are returned always as unidimensional arrays. Problem with MSVCR70.dll ------------------------ Solution from an answer of Andrew C. Goodall in the developement list: Do a file search on the pc/server where you installed .net framework The dll is there but it's in a temp folder and needs to be copied to the main .net folder. my msvcr70.dll was in C:\WINNT\SYSTEM32\URTTemp I copied it to C:\WINNT\Microsoft.NET\Framework\v1.0.3705 Then I re-installed Firebird .NET provider and all was well in the world.
