This means that you have two different version of CRT linked. Are you using any static or dynamic libraries? They need to have same version of CRT.

one or more of the static libraries you are linking to has been built using a different C-runtime version than your main application.
check the project Properties / C/++ / Code Generation, and look at the "Runtime Library" setting. they must all match.
-c

|
|
|
Both LIBC.LIB and msvcrt.lib are used, which may cause error.

I mean separating Implementation file and Header file and then including them in our main prog??
|
|
|
|

I'm going to have to assume a few things that aren't clear to me from your post.
assumption 1 : You mean adding files to a prj and not just creating hdr and impl source.
assumption 2 : You're using the cmdline compiler and not the IDE.
It's been too long since I've used Turbo C to remember, but it sounds like it's just a matter of syntax. Google should help with that, or the Turbo C help docs which I do remember as being excellent.
|
|
|
|
|
yes...your first assumtion is absolutely right but not the second one. I am using the Turbo IDE. I tried hard to find help about this on Google but gould't find any. Turbo is just used to make our base in programming (like oop).
|
|
|
|
|
There should be an option to add source files under the Project menu.

Ah yes those were the days. I wonder how many of us learnt C and C++ in Turbo C++ for DOS? Kevin

Yep, and a shelf full of books with every version.

I learned C before there was a Turbo anything but Turbo C++ was my first C++ compiler. You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

Turbo C for DOS help files were excellent. The reincarnated Turbo C++ is not only complete crap, the help is junk as well. It's a shame since I'd like to see some legitimate competition for Visual Studio.

My problum is still at the point where it started. All of you are just discussing the history.....lol.
|
|
|
|
|
That was my way of saying that I have no idea. I tried the new Turbo/Borland C++ product a few months ago and was very disappointed.
|

I don't understand where or why you're unable to add files to your project. Are you getting errors? Is the IDE not finding the files? Are you not finding the option to add them? At what point are things failing?

I have one doubt please give me the answer.
I read some where in C++, if we want to access base class constructor using derived class constructor like bellow is possible:
class base
{
base()
};
class derived:public base
{
derived():base()
{
}
};
normally i used like bellow
class base
{
base()
{
}
};
class derived:public base
{
derived()
{
}
};
My question is what is the difference between both approaches. In which cases I have to use first one and in which cases i have to use second one.To invent something, you need a mountain of junk in your mind.

I have a doubt about people who post the same question 3 minutes after they have asked it the first tiome !!!
STOP IT

sorry,
And thanks for valuable reply.
My internet connection is having problem. First time it given a message "not update your message". That's why i updated again.
Any way sorry for inconvenience. I deleted first one.To invent something, you need a mountain of junk in your mind.

In this case there is no differnce.
But consider this case.
class base
{
base(int i)
{
}
};
class derived : public base
{
derived(int j) : base(j)
{
}
}; In the above case you have to explicitly call the base class constructor like this.
|
|
|
|

For the example you give -- they are the same.
The compiler is able to figure it out -- as "base" has a default constructor... "base()"
The easiest way to see what's up here is to write both examples and run it through the debugger.

Hello everyone,
I have to do programming to make a small, straightforward game operating over a LAN
network. I think I should use Visual C++ and MFC libraries from Microsoft, because it's easy to
learn and use. Dealing with some network programming concepts such as TCP, UDP and some
Socket API is also essential.
I have no background in gaming and network programming. So, I face some difficulties.
Can you please give me some simple sample games source codes such as hangman, bingo,
puzzle etc., with or without networking, for me to get familiar with.
I appreciate projects built with MS Visual C++ 2005/2008. But any advices are invaluable!
Thank you for any help.

thats not the way things are done around here in general - you're expected to do some research and post particular questions about code - not ask for a solution to be handed to you on a plate

you sure do - if this is homework/an assignment, you'd better hit the books, start the research quickly - make google your friend
