Could not load file or assembly ‘Microsoft.ReportViewer.WebForms’

Quite a few ways to fix this:

1. Install MVC on the web server (which is not always possible).

2. In visual studio you can set dlls to copy to local on build, see the following article (please note MVC dlls have changed names slightly but it gives you the process) http://haacked.com/archive/2008/11/03/bin-deploy-aspnetmvc.aspx

3. Copy the appropriate dlls from your GAC into the bin folder of the umbraco site. To do this open "%windir%\Microsoft.NET\assembly\GAC_MSIL" in explorer and you will find all of the dlls installed in the GAC and you can copy the appropriate versions into your project. This is similar to the above method but bypasses building the project.

In terms of files you will likely need more than just System.Web.Razor.dll however this will work for all of the missing files.

The file shown above is called a "837 File". You can search for 837 file parsers or ways to parse such file in c#. I don't have a link to that but at least this should at least help you find solution (remember: "837 File")

( By the way, I believe this is a violation of HIPAA rules. You cannot publish/post this in public. Although the data might be fictitious, you cannot really post something like this. Please double check that )

03/18/10 UPDATE:

I found a "How To Read the ANSI 837 File" doc here (PDF Download)

03/26/10 UPDATE:

I found more information on this. The example might not be an 837 file at all. It appears that it is an ANSI X12 - an EDI standard. Please take a look at EDI Mapping doc (pdf)

and, also this Google Search Result on EDI X12

And, this EDI Tools for Programmer

Please post solution to this problem so anybody who needs the answer will benefit from it ;-)
