Possible to explicitly create / launch console?

ahbi82 · #1 09-Mar-2010, 19:55

To begin with, i'm designing a framework for debugging / logging / tracing for my system. There are several output options; output streams (RS 232 or http), file (probably txt) and console (more for developers debugging)... etc. The options can be mask to be enabled.

My problem is that how can i explicitly create / launch a console instead of using "main"?

Thanks in advance!

Anyway i found the solution. To add on, my framework is in DLL.
Solution is to use the windows API "AllocConsole()" when attach to process and "FreeConsole()" when detach process. Just to share this solution if someone has the same problem as me.

Well, i would use this thread to post another question. Sorry to myself if i hijacked this thread.

The problem is about forward declaration of struct nested in a class. I can't seem to get the XXXX to compile.

CPP / C++ / C Code:

// Header file
#ifndef __HDR_H__
#define __HDR_H__

// Forward declaration
struct MyStruct;

class MyClass
{
    public:
        MyClass();
        ~MyClass();

    private:
        MyStruct m_member;

};

#endif // __HDR_H__

CPP / C++ / C Code:

// Implementation.
#include "hdr.h"

struct MyStruct
{
    int myInt;
};

MyClass::MyClass()
{
}

MyClass::~MyClass()
{
}

Thanks in advance!

A forward declaration won't suffice in this case. If the compiler cannot see the MyStruct definition, then how could it for example know the size of MyClass? You have to provide the full definition of MyStruct. Also, the "pointer to implementation" (often called "the pimpl") I showed in that one thread of yours can be used in this case, since the compiler knows the size of a pointer to MyStruct without seeing the full MyStruct definition.
