Develop Reference

Same function with same arguments, from same dll reference (same path, same file), working for one .NET project, but not for an other

The .NET project that works is on .NET framework 4.6.1. The one that does not work is on .NET framework 4.7.2.
This is the Function:
return DAL.DALGeneral.SelectScalar("GetYearName", new Dictionary<string, object>() { { "Year", year } }).ToString();
This is the Error message:
[NullReferenceException: Object reference not set to an instance of an object.]

Im stumped as to why, the same function with the same arguments works from an other project.
I tried sending different arguments to the function and i get different error, but i need it to be these arguments.

Ok, so i had a missing connection string in the web.config file in the second project. I didn't realize dll reference uses the current project config file, and not his own somehow.

I believe it should be Password=Sdvavava, instead of Password:Sdvavava. Use an equals sign instead of a colon, like the other parameters.

Conflict between Sharepoint List Name and Document Library Name

I my share point site I have one List named "People List" and one Wiki Page Library named "People". I have created one visual webpart to display data from People list. I have created webpart property to read listname.The webpart property name for my visual webpart is "People". When I check whether list exists in my site using the following function it returns true:-
public static bool isListExists(SPWeb spWeb, string listName)
{
return spWeb.Lists.TryGetList(listName) != null;
}
But there is no List named "People" exists in my site. Only wiki page library named "People" exists. When I added my webpart in "MySite/People/default.aspx" page I got error.

Telerik RadGrid - what am I doing wrong?

So I get this exception from Telerik's RadGrid when using a custom DataSource but I have no idea what I am doing wrong. Any clues?

This error is happening due to some kind of (probably accidental) recursion. I'd suggest the following:
Look for something that triggers a redraw in your redraw code.
Look at your call stack when it fails and see where it is entering this endless recursion.

Lucene .NET 2.3.2 Security Exception - Medium trust Issues

Before I give up on GoDaddy and move to DiscountASP, I wanted to check if anyone would know how I can tweak the code to operate fully in a Medium Trust environment.
Thanks.

I have answered a different question on getting Lucene.Net to work in medium trust. This is on newer versions of the library.
