Hii folks,
I am new to the world of programming and I started to learn C from some weeks and I refer from some text books and some websites but I can't understand that What is the difference between Parameter and argument?

Taken out of context, this could mean a lot of different things. I guess you are talking about function parameters and arguments ? If yes, then there's no difference. It's just two different names for the same thing.

Most of us still have reasonable eyesight. There is no reason to emphasise your question in that manner. In fact, you're rather pissing people off by doing so.

I can win an argument, but I never won a parameter !

You need a reference first.

At the very least, one has a P, the other doesn't.
Being totally pedantic, parameter is the declaration of what should be passed while argument is the value being passed. Many programmers will refer to parameters as arguments, but rarely the other way around. (It seems that this is more common among older developers.)
This is a pretty good discussion: http://en.wikipedia.org/wiki/Parameter_(computer_science)[^]

Yep, that's the right answer. The C89 standard, in fact, uses those terms that way. Arguments are what's passed in the call to a function; parameters are declared in the function signature and are how functions access the arguments. I try to make that distinction in my own writing and code comments. Dunno if subsequent C/C++ standards have carried on this distinction.

Where I can find those standards?
|

You can get C89 from ANSI for $379, The Annotated C Standard for $45.95 new, $0.63 used, or the (final?) draft for free. Look in Section 1.6 - DEFINITIONS OF TERMS.

I need difference in the reference of the C Programming Language.

What I always remembered was straight out of the "Fortran Autocoder" from the late 60's "Parameters are what you want, Arguments are what you get!"

Good Morning.
Please I have a small problem about shell in Win32 using vc++.
I want to developpe small program to create an empty directory with a shortcut F9 using Hook.
As we know windows uses WM_COMMAN message to it but WPARAM magic number change since windows NT we normally use it like this "SendMessage(hwnd,WM_COMMAND,0x00000000,0)" where 0x000000 is our magic number.I'm not able to find it in spy++.Please can you help me.
Thank you.

Sorry but what do you mean by magic number? The WPARAM to the WM_COMMAND message is the value associated with the command that has been invoked, e.g. a button, toolbar or menu item.

I have to open a registry key whose length is more than 255 charecter length. I have called RegOpenKeyEx() function to open the key. But it failed. i came to know that i can call this function recussively to open such keys of long path.But the 1st call only succeed.
code piece:
DWORD status = RegOpenKeyEx(
HKEY_CURRENT_USER ,
L"SOFTWARE\xyz\Connections\<guid>\properties\",
0,
KEY_QUERY_VALUE | KEY_ENUMERATE_SUB_KEYS,
&hKey
);
in next call
DWORD status = RegOpenKeyEx(
hKey ,
L"Fallback\server\item",
0,
KEY_QUERY_VALUE | KEY_ENUMERATE_SUB_KEYS,
subkeyhKey
);
the 2nd call failed. giving error no 6. the actuall key is SOFTWARE\xyz\Connections\<GUID>\properties\Fallback\server\item
can you help me out to fix this....
thanks in advance....

Do you mean iteratively?

shouldn't be
DWORD status = RegOpenKeyEx(
hKey ,
L"Fallback\server\item",
0,
KEY_QUERY_VALUE | KEY_ENUMERATE_SUB_KEYS,
&subkeyhKey
);
?

Sorry it was a typo... I am using like this only.
status = RegOpenKeyEx(hKey ,
L"Fallback\server\item",
0,
KEY_QUERY_VALUE | KEY_ENUMERATE_SUB_KEYS,
&subkeyhKey);
Still the same error...

Since error code 6 is 'invalid handle', what is the value of the status variable immediately after the first previous call?

You have a field <GUID> missing here according to your later description of the key content.

It appears no one has mentioned it yet, but you need to use double backslashes. Instead of
L"SOFTWARE\xyz\Connections\\properties\" you should use
L"SOFTWARE\\xyz\\Connections\\properties\\"
Hope that helps.
