I just wanted to know how my program can trap a particular API
call by windows. (The idea is that I want to hook all the open text
boxes and keep hooking new ones as and when they are created).
Your question is outside the domain of comp.lang.c, which discusses
only the standard C programming language, including the standard C
library. This is a remarkably narrow topic compared to what many
people expect.
For your convenience, the list below contains topics that are not
on-topic for comp.lang.c, and suggests newsgroups for you to
explore if you have questions about these topics. Please do
observe proper netiquette before posting to any of these
newsgroups. In particular, you should read the group's charter
and FAQ, if any. If those fail to answer your question then you
should browse through at least two weeks of recent articles to
make sure that your question has not already been answered.
* OS-specific questions, such as how to clear the screen,
access the network, list the files in a directory, or read
"piped" output from a subprocess. These questions should be
directed to OS-specific newsgroups, such as
comp.os.ms-windows.programmer.misc, comp.unix.programmer, or
comp.os.linux.development.apps.
* Compiler-specific questions. Ask about these in
compiler-specific newsgroups, such as gnu.gcc.help or
comp.os.ms-windows.programmer.misc.
* Processor-specific questions, such as questions about
assembly and machine code. x86 questions are appropriate in
comp.lang.asm.x86, embedded system processor questions may
be appropriate in comp.arch.embedded.
* ABI-specific questions, such as how to interface assembly
code to C. These questions are both processor- and
OS-specific and should typically be asked in OS-specific
newsgroups.
* Algorithms, except questions about C implementations of
algorithms. "How do I implement algorithm X in C?" is not a
question about a C implementation of an algorithm, it is a
request for source code. Newsgroups comp.programming and
comp.theory may be appropriate.
* Making C interoperate with other languages. C has no
facilities for such interoperation. These questions should
be directed to system- or compiler-specific newsgroups. C++
has features for interoperating with C, so consider
comp.lang.c++ for such questions.
* The C standard, as opposed to standard C. Questions about
the C standard are best asked in comp.std.c.
* C++. Please do not post or cross-post questions about C++
to comp.lang.c. Ask C++ questions in C++ newsgroups, such
as comp.lang.c++ or comp.lang.c++.moderated.
news.groups.questions is a good place to ask about the appropriate
newsgroup for a given topic.
