C++ : Is it lots harder than c# and VB
Hi everyone, I learned Java whilst at university and have taught myself c# and VB.net. I think I am ok at it. I was thinking, these languages will probably be bigger in the future so I better get ready for them. But then, I also realised that COM is still quite important and so is C++. So I thought I better just try and have a look at C++ and COM. And now I'm scared. So my question is - why does C++ look so much harder than c#? For example : 1. The methods all have really stupid names that are hard to descern a function from. 2. You need to think about pointers and cleaning up memory. But in my preffered languages, I dont even need to think about that. Why do I need to worry about these things in C++ and is C++ really that hard - at the moment, it looks as scarry as my Gran Oh, and just how hard is it to learn COM - I've been looking all over the place and even the com section on MS's site doesnt really have that much for absolute beginners! Thanks all Simon

If you enjoyed Java, you'll probably have no problems with C++. If looking
at it scared you, it was probably ugly source code (which you can see in
Java BTW...) Get a good book on C++, the old "Interactive" series was great
as was the old "Object Oriented Programming in C++." These are good books
for starters. If you've really learned Java then you've got the major C++
hump out of the way, learning about why/what/how objects work.

If you want more power and control, then you'll need to use a language that requires you to be aware of a few more things. C and C++ are, by far, my favorite languages. It's a personal thing so that doesn't mean to much but what I like about them are the simplicity and flexibility--things that don't always go together. However, that said, I'm not sure if I'd choose to learn those languages at this time. While COM is still important, it is on it's way out. And there will undoubtedly be something else after .NET. So I personally think it makes more sense to be learning things that are on the way in rather than out. But, in the end, it depends on exactly what you want to accomplish. Jonathan

The libraries define the language and what it can (and can't) do. C++ needs no such library. The CPU and Win APIs define what it can and can't do. C++ programs the "real" computer, which depends fundamentally on things like pointers and "cleaning up" memory. The library-based languages program an abstract machine that is implemented by the library. The abstract machines are deliberately designed to make things simpler, at the cost of some loss of power and performance. Yes, C++ is lots harder. It is most appropriately used to do work that is lots harder. If all you have to respond to is user clicks then you probably don't need it. -- Scott McPhillips [VC++ MVP]
scottmcpWell C++ is a lot harder, because C*, Java etc are designed to be easier. In those languages, you are basically writing scripts which are then read by a real program which does the actual execution. There is nothing wrong with this if it achieves the results you want, but you are limiting your potential for ever writing real programs in other environments. Using pointers, freeing up memory and interfacing with devices etc are an integral part of the art of programming.

isemmelExcellent answers guys Thanks very much Simon
blah5928Jonathan makes good points, but as an aside, until another method for
providing components to more 'managed' languages comes along to replace COM,
it isn't likely going anywhere soon...

Extracting C-style string from CString
Using VC++ 7.1 How do I get a C-style buffer to a CString? With std::string I can do std::string s("HelloWorld"); printf("%s", s.c_str()); With MFC's CString (and I realise that it templated), I thought I could do CString s("HelloWorld"); printf("%s", (char *)s); printf("%s", (const char *)s); or perhaps printf("%s", (char *)s.GetBuffer()); printf("%s", (const char *)s.GetBuffer()); but nothing compiles. I have peered at the docs but I don't see what is wrong with GetBuffer() or why there is no...

More free space on drive c is needed
I have a program that requires a substantial amount of free space on drive c (system) during operation. Sometimes it exceeds the amount available. Is there a way to increase the amount of drive c free space without repartitioning? I have some free space on other drives and I am thinking about this feature of mounting ntfs volumes. How exactly is this done? <data.file@mail.ru> wrote in news:emyL2likKHA.2468@TK2MSFTNGP04.phx.gbl: > I have a program that requires a substantial amount of free > space on drive c (system) during operation.

Open C:/examplefile.xls or file.txt from another excel worksheet
Hey, people!! I need some help, I want to create an excel worksheet that checks which files are in a directory (C:\) and lists them in my worksheet. When I click on the listed files it takes me to the directory were they are located. If you can open the files when clicked even better!!! I consider myself average in vba now, but I need someone to tell me which function or built in procedure I should use. Thanks, Chay Chay, I'm not entirely sure everything you want to do here, but let me offer this as a start. This macro will list all the files in the "C: \" directory on ...
C# blocking soap requests
I have a c# program which conencts to a soap server written in perl. Everything works great except for one thing. C# or Perl is not closing the connection. That means that if another application wants to connect to the soap server and send requests it blocks until the visual studio program terminates. Is there a way to explicitly close the connection to the perl server to allow other connectinos to come in? I would assume this needs to be done on the C# side. Is that correct? ...
Serialization problem with .net vb client
Hello, We have a COM server dll that links with other dlls. Classes in these dlls support serialization. These dlls are built by VC6. When used by a ..net vb client, classes in the secondary dlls are unable to deserialize. We get the following warning from CRuntimeClass::Load: 'Cannot load <classname> from archive. Class not defined.' When used by a VC6 client, it works fine. Any help would be appreciated. Thanks. John I must add a correction. It only works fine when the secondary dlls are linked to a VC6 client, bypassing the COM server. A VC6 client going through the COM ser...
