ASP.NET using MC++ or C++/CLI Ahmed Al-Lakani3-Dec-04 21:02 Ahmed Al-Lakani 3-Dec-04 21:02  all, i was asking if i can develop an ASP.NET Pages with MC++ or even the new C++/CLI i know that someone post an article about this before, but as i can remember , someone reply and he wasn't recommending that approache, thanks Re: ASP.NET using MC++ or C++/CLI TigerNinja_13-Dec-04 4:28 TigerNinja_ 13-Dec-04 4:28  Please see this article http://www.codeproject.com/managedcpp/helloworldmc.asp[^] at the bottom (discussion) look for Nick Hodapp's post, this has a summary of implications and link to ms kb article. It has nothing to do with .cpp,.h files. R.Bischoff Tengas un buen dia tutorials needed guyaton1-Dec-04 14:58 guyaton 1-Dec-04 14:58  Does anyone know where I can find low level I/O tutorials such as writting to the boot sector, or directly to the disk. I'm sure i need to do this using assembly, but any tutorial in the right direction would be a nice start. How about a tutorial to get system information, ie. drives, cpu, ram, etc, preferable not through windows, again, probably through assembly. thanks ~Guyaton Re: tutorials needed TigerNinja_13-Dec-04 4:11 TigerNinja_ 13-Dec-04 4:11  guyaton wrote: preferable not through windows, This is the wrong board for that question. This is about MC++, that runs under CLR. Try posting in an assembler programming forum. R.Bischoff Tengas un buen dia AxImp.exe error h00ps29-Nov-04 8:47 h00ps 29-Nov-04 8:47  I have visual c++ .net 2003 and am trying to add an MSchart to a form. I've selected it from the coms list and added it to the tool box. I then go to ad it to the form and get an AxImp.exe error message telling me it can't find AxInterop.OWC10.dll even though it's in the debug directory of the project. I have the same problem if I try using any other AxtiveX component, just a different dll in the error message. natural deduction in c++ Ankit Aneja29-Nov-04 2:57 Ankit Aneja 29-Nov-04 2:57  i do not know any C++ so please explain in little detail this prob is from some one else who is very much in need-------------------------------------------------------------------------------- QUESTION: WRITE A C PROGRAM TO IMPLEMENT NATURAL DEDUCTION FOR MAX VARIABLES POSSIBLE?? YOU CAN ALSO EXPLAIN THE APPROACH TO SOLVE THE PROBLEM HINT:I WAS TOLD APPROACH OF GAMING TREE SUITS THE PROBLEM BUT NOT HAVING MUCH KNOWLEDGE OF TOPIC I WAS UNABLE TO IMPLEMENT IT. OTHER APPROACHES ARE WELCOMED. ABOUT THE TOPIC: Natural deduction refers to related proof systems for several different kinds of logic, intended to be similar to the way people actually reason. Unlike many other proof systems, it has many rules and few axioms. Sequents in natural deduction have only one formula on the right side. Natural Deduction has Introduction and Elimination Rules for each logical connective such as and depicted as "^" above. Justifications for each step shown in square brackets explicitly identify which previous lines in the proof are used, as well as which inference rule. ITS RULES ARE A B ------ [/\,intro] A /\ B A /\ B ------ [/\,elim] A A /\ B ------ [/\,elim] B A ------ [\/,intro] A \/ B B ------ [\/,intro] A \/ B A \/ B A => C B => C ---------------------- [\/,elim] C A <=> B ------- [<=>,elim] A => B A <=> B ------- [<=>,elim] B => A A => B B => A -------------- [<=>,intro] A <=> B A => ff ------- [~,intro] ~A A ~A ----- [~,elim] B ff ---- [efq] A A A => B --------- [mp] B ---- [true] tt ------- [tnd] A \/ ~A ankit Re: natural deduction in c++ Christian Graus30-Nov-04 14:30 Christian Graus 30-Nov-04 14:30  If this was not a homework question, I might tell you the right forum to post it in.

Then, the dll must be in the same directory as your application. Alternatively, (assuming it has a Type Library) you could run the COM dll through TLBIMP.EXE, creating a .NET assembly, which is even more fun. And, I think you have to use P/Invoke to use the unmanaged types and methods in your code. This is done with the [DllImport] atribute. Read this: http://msdn.microsoft.com/msdnmag/issues/03/07/NET/[^] System.NullReferenceException: Object reference not set to an instance of an object.

Does anyone know of a link to teach me how to do this? I kind of understand the part about wrapping classes, but what about so that it actually displays on the form at runtime and design time. Forgive me if I sound stupid, but I've only been learning C# for a few days now (since Friday). I think I've got the basics, but I'd like to be able to do this so that I can use the control in C#. Any help is appreciated. Thanks!! If I write code in my sleep, does that make me brilliant, or just a lazy programmer? My articles www.stillwaterexpress.com BlackDice - the programmer formerly known as bdiamond Ha Ha ursus zeta24-Nov-04 10:28 ursus zeta 24-Nov-04 10:28  You know, until I saw this question, I hadn't read the source for the C Maunder Grid Control. The MFC Grid Control is an impressive body of work (and, I didn't read it all the way through on first reading). I've never been in a project where you would have to wrap so many disparate types, but, it's probably best not to EVEN TRY to display that monster on a .NET Form. I'm fairly new to .NET, and, in particular the Interop marshaler, but, I don't think you could wrap the "mfc control class" (because there isn't one). It's not a COM component, and consequently, has no type library. If you wanted to pursue this strategy, you'd have to wrap each individual type that C Maunder uses in his implementation, and marshaling all that data into .NET accurately would surely drive you to (well, what's the worst thing you can imagine?). Run Time Callable Wrappers are generally for small cohesive units, like classes and interfaces and objects that are type compatible from managed to unmanaged. User defined types often require special custom marshaling routines, and much of this is trial and error. However, I'll bet Microsoft likes the C Maunder MFC Grid Control (they have spies everywhere), and, I wouldn't be surprised if they have a highly elite team of .NET code fiends working on the advanced version as we forum. The overriding concern here is: Just how different are MFC and .NET? I would recommend the book: ".NET and COM: The Complete Interoperability Guide", by Adam Nathan (everything I know, I learned from this book). To use this control in .NET, you'd have to re-write the entire thing to be compatible with the Common Language Runtime types. I think this would be a very cool commercial project. I wonder if Chris has franchised the concept yet. Re: wrapping unmanaged classes for controls TigerNinja_14-Dec-04 13:51 TigerNinja_ 14-Dec-04 13:51  I wouldn't try to wrap this class. You will be better off using the Windows.Forms.DataGrid class as your base implementation (powerful class by the way) and extending it for any further functionality that you desire. Remember, the DataGrid is different for Windows and Web namespaces respectively. R.Bischoff Tengas un buen dia
