Hello,
I'm having to classes with inverse assotiations, which means one has to include the other. But neither my MSVC nor my GNU compiler doesn't handle that. I don't understand why?
MSVC Compiler error: Syntax error: identifier 'B'
Syntax error: identifier 'A'
GNU Compiler error: variable or field 'foo' declared void
expected ';' before '(' token
Here is a code example:
#ifndef A_H
#define A_H
#include "B.h"
class A
{
public:
A(void);
virtual ~A(void);
void foo(B* b);
};
#endif
#ifndef B_H
#define B_H
#include "A.h"
class B
{
public:
B(void);
~B(void);
void foo(A* a);
};
#endif
Thank's for your replies,
boogalo

You have to include the files in the cpp files and use a forward declaration of classes:
class A;
class B
{
};
Including a header means that the code from the header will be 'pasted' instead of the include directive. Imagine then what happens in your case

Try the following code as this is due to deadlock for proptotypes of class A and class B
// B.h ----
#ifndef B_H
#define B_H
class A;
#include "A.h"
class B
{
public:
B(void);
~B(void);
void foo(A* a);
};
#endif
Knock out 't' from can't,
You can if you think you can

#define B_H
class A;
#include "A.h"
#include "A.h" is redundant use only forward declaraton ie class A

Thank You all for the quick response!!!
That worked out well. now it's compiling

instead fo including the header file you can do forward class declaration and
class A;
class B
{
public:
B(void);
~B(void);
void foo(A* a);
};

Hello,
I am trying to make a small paint application and want to allow user to draw only in three colors Black, White and Red.
I create a 4BPP DIB with a Pallete with White, Black and Red as top three entries and rest all initialized to black.
I copy the same Pallete on the Device Context.
When I Draw a Line with solid red pen and ROP set to R2_MASKPEN but the line is drawn in white color although it should appear as red.
Can anyone help me out here.
Regards,

I've just found this in some code I've been given to maintain:
inline char * _fstrchr(const char *szStr, char ch)
{
return strchr(szStr, ch);
}
It's in a .h file, and it's used all over the place. Is there any benefit with this function over using strchr directly? I thought inlined functions basic replaced the _fstrchr token with the content of the function - as the function is not doing anything else, is there any point?

He used this token, _fstrchr, in the entire source. There's a benefit from this way:
Some time later when there is a need to alter the implementation, he only needs to modify one line, instead of using the text search function to find out all the occurrences of strchr.
Similar concept as:
#ifdef UNICODE<br />
#define _tcscpy strcpyW<br />
#else<br />
#define _tcscpy strcpyA<br />
#endif

Add your application.exe path at the following location in the registry.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\
StandardProfile\AuthorizedApplications\List
i have not tried the code but hope so it work.  As the windows firewall adds the authorised application list here.

Another way to modify the firewall settings is to use the following command(s):
netsh firewall add allowedprogram executablepath DisplayNameInExceptionList Enable All
If you just enter netsh firewall add allowedprogram in a CMD window it will bring up the help.

Music will only play if you post your question in the C++/CLI[^] forum.
