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

|

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);
};

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.

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.

If MacOS is OS/X, then you should be able to use opendir(), readdir(), e.t.c.
In OS/9, it's a completely different story.

I have used a combox control in my program.
When I select item in the combox control, the item will be highlighted.
How to solve this problem?
Please help!

What problem?

The selected item was always being highlighted.
It is possible to make it not be highlighted?

Override the CBN_SELCHANGE, use SetFocus to set the focus on the other control.

if you want the selected iTem should be highlighted then you can use:
GetCurSel and SetCurSel

I have tried it.
After the SelchangeCombox(), I use the GetCurSel and then SetCurSel it again.
Is there anything wrong?
Please help!

Set its type as Droplist instead of Dropdown
and one more problem for us is clearly specify your problem .
