Ogre with clr:pure - it is possible?

Hello All!

I try to use Ogre with Windows Forms UserControls. But use of a UserControl requires compilation of the project in a mode clr:pure.

Whether probably to combine Ogre and this mode?

What is UserControls? Mogre is used by OgreStudio successfully with Windows.Forms I believe.

Yeah, Ogre Studio uses Windows.System.Forms.UserControl as the base for most all of its controls (including the OgreViews).

I'm not sure what mode CLR:pure is, but out of the box, Ogre + Mogre + .Net works fine

But use of a UserControl requires compilation of the project in a mode clr:pure.
Well to be more exact UserControls compile fine with /clr, it's the designer that for some buggy reason can't handle them.

Whether probably to combine Ogre and this mode?
Nope, /clr:pure means no native code.
You should probably build your UserControls in a separate /clr:pure project and reference Ogre through a managed interface.

Or use Mogre and save yourself the trouble

Thanks by All! I will try to use MOgre. But I have one question:
I want use only C++ languege. Whether it will have an effect on productivity in comparison with original (clean) Ogre?

If you use only C++ then Mogre is a wrapping layer you don't really need, so I'd suggest sticking with C++/CLR.
Build the UserControls with /clr:pure and link them to another mixed-mode (/clr) library that makes the real calls to native Ogre.

I tried this. I have the separate project FreyOgreApp, in which I create and init Ogre with some public functions from class COgreApplication.
I compile it in mode clr as static libraly (.lib)

Then I create WinForms application and simply add libraly to input. When I try to link program, a have this.

If I add FORCE:MULTIPLE option to Linker Command Line, the above errors comes warnings, but last error does not disappear.

How to link OgreApp (clr) and WinFormsApp(clr:pure)?

I compile it in mode clr as static libraly (.lib)
Actually I was suggesting that your user controls interface with Ogre through a dynamic link library.

Sorry for a noob question, but how to add reference to FreyOgreDll? I assume, that there are in Input Linker Settings?
Also I create FreyOgreApp.li to link my DLL with project. But how? (VS2005)

how to add reference to FreyOgreDll?
There are 2 ways:

-either go to Project Properties -> Common Properties -> References and press the "Add New Reference" button

-or, in your code, before using all the managed classes etc. from FreyOgreDll, add this:
#using "FreyOgreDll.dll"

Both ways will allow you to use a managed DLL (the managed classes from a /clr library) by a C++/CLR project

I tried 1st method, but it don't work, beacause the Character Set option was "Use Multi-Byte Character Set". I fix it to "Use Unicode Character Set" and I could add reference successful.

Thank you for help! )
