I actually found myself admiring your restraint on this one.

Why is common sense not common?

He stopped distributing the source code files. I need to start thinking outside the box more, as that solution never occurred to me.

that's funny, it's the first time i see someone delivering source codes expecting the user to compile the application before the first use Roll eyes | :rolleyes:

You are obviously no Linux-Expert.
They actually have whole Distributions where you Compile the whole thing from the ground up. WTF | :WTF:

Hmm - I never tried in the last few month. But WINE is making progress...

In fact, giving out the source-code for self-compiling is less common in Windows but not unheard of.

And now I must congratulate you to your patience with this guy Rose | [Rose]

don't misunderstand me. of course i know such a thing happen (i'm not an expert of the unix/linux world as you stated, but i know some basics). what i mean is that i had the feeling that the OP was building something for a particular customer of his (not general build for whoever wants it), and don't want to distribute his sources. It's in such a situation that i never heard of anyone working in Software development who didn't even know how to build a program...

nope, i'm pretty sure he's not, because i already saw him there asking some intersting questions (newbie questions btw). I think that he is just lost in his mind...

No it doesn't you would have to download other software to compile it in linux (i forget the software but you can get it free).

Granted most software for linux is open source, but even so there are usually pre built binaries which can be downloaded instead. There are even some software companies that refuse to release the sources for their linux binaries.

Well, that's simple: just distribute the exe and the resources and don't distribute your source code.

Or maybe I misunderstood your question... Unsure | :~

But what if they somehow manage to track the .exe back to your office and rummage through your computer to find the corresponding source code? Whatcha gonna do then, Cedric? Big Grin | :-D

Hi all
I want to create a thread in a Win32 Console application . I added a class and in the constructor i call like this ...

CMyClass
{
public:
HANDLE hThreadID;
DWORD WINAPI ThreadFunc(LPVOID pParam);
}

... in myclass.cpp

CMyClass::CMyClass()
{
hThreadID=CreateThread(NULL,0,ThreadFunc,this,NULL,NULL);
}

But I get the following error when I compile it ...
rror C2664: 'CreateThread' : cannot convert parameter 3 from 'unsigned long (void *)' to 'unsigned long (__stdcall *)(void *)'
None of the functions with this name in scope match the target type

I have added afxwin.h in stdafx.h. I do not use MFC . IS there anything missing ?

Please, when posting code, use the pre tag !

Your problem is because you pass the address of a member function to your CreateThread function where it expects a global function. The difference is that they don't have the same prototype: for the member function, there is an extra parameter that is passed implicitely (the 'this' parameter).

The way to solve this is to pass a global function (or a static function of your class) to the CreateThread. If you need to run your thread in a member function of your class, then pass the this parameter as a parameter to your function and cast it back to the class in the thread function (so this way you can call a public function of your class).

Wow...I got it . I tried both the things and now its ok ..
I changed my member function in the class as "static DWORD WINAPI ThreadFunc()" and also I removed this member function from the class and made it a global one . In both the cases it compiled properly .
Can I infer the following ?
1) Making a member function as static one makes the function (more or less) a global one .
Is it ok ?

In fact declaring a static function in a class means that the function is accessible even when you don't have an instance of your class:

CMyClass::myStaticFun();

In that cas, you are able to access the function with the :: operator. Of course that also means that the function doesn't belong to any particular class instance, thus it cannot access any non-static member of your class (either metohd or variable).
