Managed C++/CLI

Hi Paul, Thanks for the bit from the Ronald Laeremans; there's nothing like inside info :) I had been wondering why the compiler treats pointers to __value parameters the same as declaring them as C++ references. Knowing that this stuff is ".Net official" makes me feel better about the future for code I've written. Please feel free to post anything else you get from the inside! Sorry I didn't cover passing __value types in my first post; I was only talking about types that are already "CLR reference object"/pointer types, when I talked about pointers to pointers. I pass __value types the same way you did (as a C++ reference), and skip the pointer syntax. Cheers, Jeff

You only have to marshal your strings to CLR Strings, since all CLR reference types (including String) are based on Object. Then you can Add() your Strings to an ArrayList. If your std::strings are strictly lower ASCII (and I do mean 7-bit ASCII, not MBCS/ANSI), the following method will work: using namespace System; using namespace System::Collections; using namespace System::Text; using namespace std; vector vec; string s = "a std::string"; vec.push_back(s); ASCIIEncoding *enc = new ASCIIEncoding(); String *sCopy = new String(vec[0].c_str(), 0, vec[0].size(), enc); ArrayList *al = new ArrayList(); al->Add(sCopy); For anything beyond English, you will need to use either Marshal::PtrToStringAnsi() or MultiByteToWideChar(). I could explain that if it's what you need instead. Cheers

For future reference we would appreciate it if you would not post the same question more then once across the different message boards, I believe you asked this exact question in the .NET Framework board also. Thanks:cool: "We will thrive in the new environment, leaping across space and time, everywhere and nowhere, like air or radiation, redundant, self-replicating, and always evolving." -unspecified individual

Yes, you can do so. You can make the pointer as a syetem parameter which will be sent to another application. And the another application will get the system parameter--the pointer when the specified application is going to run. I guess you are sure to know that an application can accept command line that is just system parameter. Good luck! stanley

It is unclear exactly how you need to pass the vector data, whether anything needs to be modified in C#, and so forth. One question is whether you could re-implement all this in MC++ (or C#) from scratch to begin with. That is, populate ArrayLists from the get-go. If you have no choice but to pass unmanaged stuff to managed code, you will likely need to copy everything into managed (GC-collected) memory. If everything is largely primitive types (except the vectors, of course), then that shouldn't be too bad. If you need to pass values/changes back to unmanaged code, you will have to copy again. Obviously, it is best to minimise how much data must be marshaled back and forth between unmanaged and managed memory. If the "vectors" need to be dynamic within C#, then ArrayList seems like a reasonable choice, though performance will not be as good (if nothing else but because everything will have to be handled by pointers to the base Object class). If performance is not a major consideration, then go that way. If nothing needs to be modified (i.e., not dynamic) in C#, then __gc[] arrays are more efficient, and more flexible in MC++ than in C#. If you can be more specific about how the vectors need to be used, perhaps I could be more specific with any suggestions. I have been swimming in the regions between C++ and MC++ for quite a while now. Cheers

That's very nice approach. But I can't change the structure because that function in a DLL. I can interfere to interface of the library. Ahmet Orkun GEDiK

As default a service runs as the "System" user. This user dont have permissions to access shares on other computers. You have to change toe user that the service logs on as. Change that to a user that have permissions to access the share, then it works ;) - Anders Money talks, but all mine ever says is "Goodbye!"

You can use inter-process communication for communicate two or more processes. Take a look Threads, Processes & Inter-Process Communication title. Ahmet Orkun GEDiK

I've a similar problem and I don't know how to solve it. I hope some Guru here knows the solution. Jenny. C.H.Y.S.P.R.xxx
