Body
I have a code written in C++ (that I did not write) and want to use it in C#, so I decided to make a dll and use this class from there. I have very little knowledge of C++ and am having problems referencing the methods of this class in my C# project. The C++ code is like this: <pre><code>#ifndef BeamAn_class #define BeamAn_class #define DllExport __declspec( dllexport ) #include <vector> #include <cmath> using namespace std; public class DllExport BeamAn { public: BeamAn(); ~BeamAn(); bool SetGeometry(vector<double>); //I didn't put the DllExport here because I already did it for the whole class. It's okay to do this, right? //other public methods an stuff private: //private methods an stuff } #endif </code></pre> In my C# project I added the reference to the C++ dll normally (right click on the project, add reference. The .lib and .h files are in the same folder of the dll). But looks like Visual Studio can't "see" the methods of my class. I can create a object of the BeamAn type, but can't use any of its methods. For example, I can do this: BeamAn contBeam = new BeamAn(); But can't use any of the methods or atributes inside the class, like this: contBeam.SetLoadFactors(1.0,1.2); Visual Studio says that "BeamAn does not contain a definition for 'SetLoadFactors' and no extension method 'SetLoadFactors' accepting a first argument type 'BeamAn' could be found (are you missing a using directive or an assembly reference?) Is there more something I should write in the C++ code to make the dll work properly, or am I doing something wrong when referencing it? I know that I'd have to use "DllImport" in my C# code if I was explicit linking, but that's not what I want to do. Thank you very much!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
