VB to C# Conversion Errors

I have 3 small VB.NET projects that were converted to C# and the C# converted application have some errors, I would like to get the errors fixed so that the programs compile and run. I have included a Zip file that has the original VB.NET programs and the converted C# programs so that you can see the errors. I have also included that database that is used. You can attach the database to see it also.
