Thanks Christian. I've just posted this in the c++ forum. I am using vc++ but I am building it for a c#/asp.net website. I guess I should have put the horse before the cart.
Thanks,
Craig

Hi,
I was wondering what is the maximum limit (size) of an RWCString. I believe, it used to be 64K with 16 bit plateforms. Is there any limitations in 32 bit and 64 bit plateforms? Will appreciate if you could provide me this info.
THanks

What is an RWCString ? Are you sure this is a C++/CLI question ?

This questions pertains the the Rogue Wave C++ library (tools.h++). Should I be posting this in another section?
Thanks

OK, then it belongs in the Visual C++ forum, or, better, a forum dedicated to that library.

Dear All,
i have a Unmanaged c++ based Library and i want to use it C#/C++ application(i.e. it expose some c based function .. ).. could some one give some pointer to use unmanaged library in c#/C++.. so that i don't have to provide some extra dll or lib with c#/C++ to my end user....
thanks in advance

If you cannot convert the library to a managed-mixed mode assembly, and...
you cannot add another DLL that is a managed-mixed mode assembly, then...
I believe your remaining choice is to use PInvoke or, COM Interop if your library has any COM interfaces, from your managed application project. Keep in mind you can only deal with C API's using PInvoke (exported _cdecl functions) and/or COM interfaces, meaning you will have no access to C++ classes defined in the library from managed code.
IMHO if you cannot convert the original library you should take the option of delivering another DLL that is a managed-mixed-mode assembly.

any pointer to do that! i..e converting C++ Library to mixed mode assembly...?

No but maybe Google[^] does 
If you have the source for the project and the old project was a Visual Studio project then you just open it up in VS2005 and change the project settings to support the managed platform. There is more like #include's etc., all the information is available on msdn.com. I would also guess there is an Article here on Code Project.
Even if you don't have an old VS project, as long as you have the source files you can create a project from scratch and add the source files to it.

That's not possible. You can't convert C++ to C#, and you can't have more than one language in your program. Certainly if you could, the two would not be C++ and C#. You need to pinvoke a dll.

I think that the cleanest way to access unmanaged functionality in .NET(c# or C++/CLI) is to write
a wrapper in C++/CLI. There you will have an extra .dll, but you have bounded all unmanaged code within that
.dll.

Hi,
I am new to C++. I am used to programming in java and vb. What I am trying to do, just for the fun of it (and to learn c++) is write a poker analyser. What I would like to do is draw a poker table, and to this add controls so that I can receive input from the user. Does anybody know of a good tutorial that I could follow on this type of creation (doesn't have to be a poker table, could be any type of display that accepts input? I already have underlying code, cards, decks, hands etc but haven't been able to figure anything out about interfaces!
Many thanks, sorry if it is a bit vague, Ron

If you're using C++/CLI, the Graphics class contains all the methods you need, just call Invalidate() whenever you want to draw your form, and handle the forms paint method.
If you're not using C++/CLI, you are in the wrong forum.

Hi all,
I am attempting to create a program that permanently deletes selected file(s) from a hard drive using System::IO::File::Delete(path).
As far as I know this method works as the file is no longer exsistant, at least not in that location any longer. After checking the recycle bin I know that the files are not sent here after calling Delete.
I was just wondering if anyone knew where the deleted files are sent if they are sent anywhere.
Thanx,
7leaf

They aren't sent anywhere. Also remember that the data on the disk isn't "wiped"...its data
locations are just marked as free 
I haven't seen any .NET way to delete files to the recycle bin, although the SHFileOperation() API
is always available for that.

Of course you don't, no one does. It never happens. It's a dumb question... skip it."

They are sent to rest in peace (R.I.P.), untill someone (usually police officer) uses his specialist device to read your HD and "resurrect" them ;]

You could search the articles here at Code Project.

Hey I need lots of money, how much can you offer?
System.IO.Path.IsPathRooted() does not behave as I would expect

Is better you ask about your problem not I need to a code.You can starting to write it and if you have problem then ask about your problem

You have several issues.
1 - this is the C++/CLI forum. If there's a place for C questions, it, by definition, is not here
2 - this sounds like a reasonably complex task. One has to ask how you got this far in your course, if you can't read.
3 - We're not here to do your homework, and if we did do it, you wouldn't be learning, now would you ?
