I have set a conditional compilation preprocessor directive in the
Project>Properties Build page. The variable is retained in the project when
exiting VS and returning. However, the code that is based on that
preprocessor is not honored when entering VS. I have to remove the
preprocessor variable, save the properties and then re-enter the...

I have a preprocessor constant (SUPPORT_PNG_IMAGE) with 3 states, to control the compilation:
---------
#undef SUPPORT_PNG_IMAGE
#define SUPPORT_PNG_IMAGE
#define SUPPORT_PNG_IMAGE ONLY
---------
With the 1st & 3rd line the following line works
---------
#if SUPPORT_PNG_IMAGE == ONLY

Let's say you were wanting to write code usign early binding to the MSXML
library, but then be able to switch between early and late binding at will.
Conditional compilation is one possibility, but it's not practical.
1. You have to put a precompiler condition block around every Dim and
every function...

Greetings C gurus,
I have used preprocessor directives since a very long time. But
whenever I see some professional piece of C code, the linux kernel for
example, I get literally confused by the amount of preprocessor
directives used in these code.
Can anyone please tell me how to actually use these preprocessor
directives in a more...

How can I make certain code parts be compiled conditionally, depending
on the definition of a macro such as:
#define VERSION "2.3"
Is it all right to do things like:

Hi,
Could I ask some questions about the conditional compilaion? Suppose I
have three simple files: a.c, b.c and c.h
/* --------a.c--------- */
#include <stdio.h>
#include "c.h"
int main()

I have never really used the preprocessor commands so this may seem like a
newbie question.
In my development code, I short circuit certain variables being set by
hardcoding them. So for example I would say something like
PlanID = 1;
However, in the production code, PlanID comes already assigned to me and if
I keep this assignment, I...

I'm trying to use the gpp utility (Gnu points to http://en.nothingisreal.com/wiki/GPP)
to do conditional compilation in Python, and I'm running into a
problem: the same '#' character introduces Python comments and is used
by default to introduce #ifdef etc. lines.
Here's an example of what I'm trying to do:

Hello!
Can the proprocessor make conditional decisions. Here's an example of
the functionality (not standard C!)
#define PUT_BYTE(const_index, val) \
#preprocessor_if (const_index == 0) \
({ *(77) = (val); }) \
#preprocessor_else_if (const_index == 1) \
({ *(99) = (val); }) \

All,
I'm looking for a tool that is able to take my code base (which is
full of preprocessor directives) and spit out source code that is
"clean" of any preprocessor directives based on the options I choose
(possibly via some kind of user input screen).
Does such a tool exist? A Visual Studio plugin would be even better.
FYI: I have...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
