.NET Forum / Languages / Managed C++ / August 2007C++/CLI wrapper generator
I have a lost of C# classes from many DLLs to use from my legacy C++ EXE application. Is there a generator that would use reflexion (for example) to generate a C++/CLI wrapper. Hi zolof! > I have a lost of C# classes from many DLLs to use from my legacy C++ EXE > application. > Is there a generator that would use reflexion (for example) to generate a > C++/CLI wrapper. I dont't understand your question... If you want to use C# DLLs (assemblies) than you do not need to generade C++/CLI wrappers... just use the assemblies... Or maybe I missed the point... Just compiler your EXE with /clr and use the C# DLLs....

Can you not just compile with /clr and use the classes directly? For the moment my MFC source code is compiled using VC++ 6. Thanks to Microsoft, I cannot compile it using /clr. I don't want to migrate because it cost a lot of efforts and because VS2005 does not generates the same exe. The exe will be bigger, slower to execute, and not compatible with default libraies installed with Win98 and Win2000 (I will need a new crt, mfc8.1 and atl8.1). Also VS2005 is much slower to use and to compile than VC++6. VS2005 is good only for .NET and specific C++ dev (like smart phone dev). > >I have a lost of C# classes from many DLLs to use from my legacy C++ EXE > > application. > > Is there a generator that would use reflexion (for example) to generate a > > C++/CLI wrapper. > > Can you not just compile with /clr and use the classes directly? > For the moment my MFC source code is compiled using VC++ 6. > Thanks to Microsoft, I cannot compile it using /clr.

Your legacy C++ EXE aplication has a lots of C# code??? Regardless, I faced a situation where I wanted to wrote GUI in a managed forms application; and my core libraries were unmanaged C++. I wrote simple managed wrappers around exposed classes from the unmanaged libraries; so now I can keep legacy C++ code, and develop UI in a managed way. If that what you need, let me know, I will share how I did that. [ http://groups.google.com/group/medicalimagingscience ] I have many .NET assemblies to be used by one legacy exe. For the exe (VC++6) to be able to use the assemblies (C# 2.0), I need to develop some wrapper DLLs (C++/CLI) since I don't want to use COM interop. I am looking for a software that would use reflection to analyze my .NET assemblies and generated the wrapper DLLs automatically. I am sure this is possible and I will make ity myself if there is no way to buy such a tool. > For the moment my MFC source code is compiled using VC++ 6. > Thanks to Microsoft, I cannot compile it using /clr.

You'll need not only the updated CRT, but also the entire .NET Framework installed. Actually, VC2005 generates better code than VC6, your executable will be smaller or faster (depending on what optimization settings you choose) just by recompiling your standard C++ source code. You can also statically link the new CRT so you don't need to install it separately, but not if you want to run managed code in the same application. You really need to decide between avoiding the new CRT dependency and using C#. You can't have both. Free MagazinesGet these publications absolutely FREE for up to 12 months.
