Value cannot be null

Question

VS 2010 reports this warning "Value cannot be null." However, the project seems to be compiling in order. It does not show any other information that shows why this is happening. I am developing a project to run in Microsoft Robotics Studio.

Description: "Value cannot be null"

File: ** dssproxy

How can I find more information about this warning?

Code - 3000+ lines. So I'm not sure if it's worth posting here.

Thanks in advance.

Answer 1

Thanks for all the suggestions.

In the end, it was the missing namespace in one of the files that I added as a link. Perhaps that is why dssproxy.exe complained. It was not very obvious that "Value cannot be null."

Could not find out if I did not start from scratch: (.

Thanks again.

Answer 2

The problem sometimes arises from adding code for the control to your form, and then removing the control and leaving the code. Try the commneting code this time so that you understand what exactly causes this error.

Another possible reason is that you may get this error when creating a component or control on a design surface from a toolbar. The most likely reason is that you are trying to use a component or control that was created for a 64-bit build. Visual Studio development environment does not support 64-bit components.
