Hi all,
What's the most appropriate place to define this.
TCHAR szTempFile[MAX_PATH];
I've define it on the header file, is that OK.
I appreciate your help all the time...

No - it can cause problems. If the header file is included in more than one source file (i.e. a body file) then the linker will complain about szTempFile being multiply defined (actual error will depend on your actual compiler). Effectively each body file gets its own variable with global scope called szTempFile. When the linker comes along it sees multiple versions of the variable and causes the error
The rule is that a variable name can be declared more than once but only defined once. The above line is a definition. Definitions should always live in the body files. If you want to share the variable between multiple body files then you need to include a declaration of the variable in the header file. You do this by putting the keyword extern in front of the declaration as follows
extern TCHAR szTempFile[MAX_PATH];

Which compiler? I created a test project in VS2003 and it works fine
File foobar.h
#pragma once
extern TCHAR szTempFile[MAX_PATH];
File foo.cpp
#include "stdafx.h"
#include "Foobar.h"
void DoIt()
{
szTempFile[0] = _T('a');
}
File bar.cpp
#include "stdafx.h"
#include "Foobar.h"
TCHAR szTempFile[MAX_PATH];

if you're coding C++, the best place for such a declaration is still in the class definition, as a member...
|
|
|
|
|
The most appropriate place is the place that gives the variable
the scope you desire.
If its scope is the duration of a function, put it in a function.
If its scope is global, put it anywhere outside a function.
etc...
Header files are typically for declarations. Variable instances
should be placed in source (c/cpp) files. Yours is an instance, so
shouldn't be in a header file.

Well, you have to parse the single lines, using, for instance CString::Tokenize [^].

You can use of CString::Find.

It has returned error code 87. Having been referred to MSDN, i came to know that this error code indicates that one of the functions parameter is invalid. But i am not having an idea about which parameter i am passing wrong.
Any clue?? Your help would be greatly appreciated.
Thanks

if(nStatus != NERR_Success)
// MessageBox(hwnd, (LPCWSTR)"Failed", (LPCWSTR)"Test", NULL);
fprintf(stderr, "NetUserGetinfo failed with error: %d\n", nStatus);

I am using above code to change admin rights user to limited rights user. Is it possible with this code.

Hi
I need to get the name of the local system Administrator (System is in the domain). As that name however appears in the ControlPanel->"UserAccounts" list or ControlPanel->AdministrativeTools->ComputerManagement->LocalUser and Groups->Groups and clicking on "Administrators" Group, I am trying to list out all the users under "Administrators" Group and for this purpose I am using NetLocalGroupGetMembers() and including lmaccess.h file. But I am getting the linker error "error LNK2001: unresolved external symbol _NetLocalGroupGetMembers@32". Doesn't this header file "lmaccess.h" come with Visual Studio?
Using ADSI, I can get the members of an "Administrators" group (local system) , however, that list doesn't include the name of the the local system administrator , who is a member in the domain.
Is there anyother alternative mechanism/function to get the local system Administrator Name?
Thanks in Advance.

You need to add Netapi32.lib to your project.
If you are using VS6, take
project settings->Link Tab and in that you can find a edit box "Object/library modules". Enter Netapi32.lib in it.
