Communicating between windows application and class library

JoeMcCollum — Fri, 22 Mar 2013 20:25:21 GMT

As some have pointed out, there are some things that cannot be done in a Windows Application (go into VB.net and create "Windows Application. You can launch ArcMap and load a shapefile but not color it.)

So you need a Class Library. Is there some way to attach a form to a class library? I need some user input.

I tried using the form in the Windows Application, then writing a shapefile in the Windows Application then reading it back in in the Class Library. That seems to not work.

I assume that you are writing a standalone application here, i.e. not in the context of ArcMap.

In this case whether you put the code in an application (EXE) or a class library (DLL) does not matter. It is just code. The only reason to put in a class library is to make your code modular potentially for reusability.

Class libraries can have forms. When you compile a class library it produces a DLL which has to be loaded into a host process (EXE). If the host process is ArcMap then you have a very rich set of functionality available to you. If the host process is a standalone application (e.g. YourProgram.exe) then the set of functionality is more limited. So what limits you is functionality provided by the host process.
