you are lucky.. MSDN provided you example in CFileFind::FindNextFile()

Hello everyone,
I am wondering whether the generated binary code on Visual Studio integrated mobile simulator is the same as that of real device (for example, real HP ARM iPAD)?
Is the answer to the question (binary code on simulator is the same as that of read device) the same to all Microsoft mobile development IDE -- embedded VC 3/4 and Visual Studio 2005?
thanks in advance,
George

It's a precompiled directive, which means that it will be evaluated before the compilation starts. In this case all the code in between will be 'discarded'. Here it is not very usefull (the programmer probably wanted to test a piece of code and use this to 'remove' it from compilation quickly).

that are compiler directives.. as you see if you pass false in if statement nothing will be executed same here is also goign

In addition to the other responders, pre compiler directives are very usefull.
Lets say yo wanted a common code base for different eivironments you would use #ifdef #elif #endif commands.
So, for eaxmple,
#ifdef WINDOWS_NT_4
// do NT 4 specifc code
#elif
// do code for everything else
#endif
You of course need to compile different modules then for NT4, and everything else, putting the WINDOWS_NT_4 define in a header file, or make file.
Truth is the subjection of reality to an individuals perception

It is a preprocessor directive. The code in between #if and #endif only gets passed on to the compiler if the preprocessor evaluates #if to true.

currently, i have a private function in cat named privateFun.
i would like to have this function "private" to all except dog's action member function.
by using the following approach, all the dog's members can access all the cat's private members.
// cat.h
//
#ifndef CAT_H
#define CAT_H
// forward declaration.
class dog;
class cat
{
private:
friend class dog;
void privateFun() {}
};
#endif
//
// cat.h
// dog.h
//
#ifndef DOG_H
#define DOG_H
#include "cat.h"
class dog
{
private:
void action()
{
cat c;
c.privateFun();
}
};
#endif
//
// dog.h
however, i would like to have ONLY dog's action member function to access cat's private members.
i try the following approach but can't work.
// cat.h
//
#ifndef CAT_H
#define CAT_H
// forward declaration.
class dog;
class cat
{
private:
friend void dog::action(); /* HERE IS THE CHANGES AND COMPILATION ERROR HAPPENS HERE. */
void privateFun() {}
};
#endif
//
// cat.h
// dog.h
//
#ifndef DOG_H
#define DOG_H
#include "cat.h"
class dog
{
private:
void action()
{
cat c;
c.privateFun();
}
};
#endif
//
// dog.h
Of course, i would get the following compilation error:
c:\Documents and Settings\YC Cheok\Desktop\aaa\cat.h(10): error C2027: use of undefined type 'dog'
However, I just cann't include the dog header file into cat. This will introduce circular include problem.
Any advice? Can I have something like member function forward declaration? Thank you very much

You can declare the other cat function as protected.
In that case, the dog can not access to that function

Hi,
well, it's for sure a simple problem for an advanced MFC user, but I don't know how to solve it 
Here's what i want to do: I want to create a MFC controls dynamically to my MFC dialog without the use of the resource editor. E.g. a simple static text at the coordinates 0,0 with text on it? The reason I'm asking is that I have to add 120 leds/labels to a dialog and I don't want to make it by hand, because if something changes, I have to redo everything, Or if I want to add tabs later.
Thanks for your help.

Hi,
This is simple window - you can add the new e.g. by CStatic class (derivied from CWnd):
CStatic * myStatic = new CStatic;
myStatic->Create( _T("my static"), WS_CHILD|WS_VISIBLE|SS_CENTER, CRect(0,0,150,15), pParentWnd );

don't forget to delete the MyStatic object

Now to the next problem 
I'm using the following controler: http://www.codeproject.com/buttonctrl/LedButton.asp[^]
It's an LED button, which interhits from CButton. I can actually create a CButton dynamically, but it doesn't work with this CLedButton class. If anyone has five free minutes, it would you could say why it doesn't work this this control

Hi,
hm do you mean something like that:
CLedButton * led = new CLedButton;
led->Create( "an strange text", WS_CHILD|WS_VISIBLE|BS_AUTOCHECKBOX, CRect( 2, 2, 120, 20 ), this, iCtrlId );
led->SetIcons(IDI_GRAY_LED_ICON, IDI_GREEN_LED_ICON);
...
...
...
delete led;

Yes, thanks. I found it out on my own at the same time and wanted to post it here, but you were faster
The BS_AUTOCHECKBOX flag needs to be set, otherwise the class asserts.
Damn, I have the feeling that asserts are really bad implemented. I'm using my non-mfc application an custom assert, which brings me directly to the line, where the assert happend and not somewhere deep in the MFC, where I have to search the huge call stack for the place, where the real assert happend.
Anyway, thanks for you help

better make a call to DestoryWindow before deleting variable or make call to delete at destructor or OnDestroy Window handller
