Hi,
I have one constant variable and want to use it in two files. I put it in
the header file and then include the header file. The compiler always say
"error C2370: 'arraysize' : redefinition; different storage class". What
shall I do? Files are listed below. I'm using Visual C++ 6.0
By the way, how to use STL (vector , for example) to create a
multi-dimension array?

The following program compiles fine but elicits this message from the
linker: "undefined reference to VarArray::funct" and thus fails.
It seems to behave as if the static data-member: VarArray::funct were
an extern, but it is declared in the same file (q.v.). What is the
remedy for this?

After many years of dealing with definition and linkage issues
in ways that I know to be safe, I've decided it's time to try
to understand this area properly. Consider a header file with
the file scope declaration
int i;
This header is included in two files that refer to i but do not
declare it. The two files build together into a single program.

I would like to share a variable between two functions defined in two
separate source files; no other functions will need the global variable
so I'd prefer to not give it file scope. Thus, I want a variable with
local scope, external linkage, and static storage.
I believe I can do this for the file that does not define the variable
by declaring it inside a function. Can I also avoid giving it file
scope in the file that does define the...

Hello,
I am having a problem with the cl compiler. I have written a C class
(RegConnect.c) which uses Win32 API functions such as RegOpenKey,
RegCloseKey etc. Initially when I was trying to create a dll, using
the cl compiler I was getting many unresolved external errors, Example
1 below (8 in total, 7 to do with the registry function calls and 1
from wsprintfA call) as I hadn't included the AdvAPI32.lib file. So I

I have a system that was originally developed in asp - the pages are saved in
SQL (there are over 10,000 pages) and saved to a temp directory in the server

I have updated this system and changed the pages that are saved to the
server as aspx - everything works fine and pages can be served - but
Its not impossible for a single client to request 100 plus pages in one
session - as each page is requested it is...

Hi
Can I trigger an external program to run when a new record is added to
the mysql table?
The external program is in C and instead of scanning the table
continuously for new insertions, it will be better if an external
program could be triggered.
Any suggestions?

Is it possible? Bestcrypt can supposedly be set up on linux, but it seems
to need changes to the kernel before it can be installed, and I have no
intention of going through whatever hell that would cause.
If I could create a large file that could be encrypted, and maybe add
files to it by appending them and putting in some kind of delimiter
between files, maybe a homemade version of truecrypt could be constructed.
Any idea what it...

Overview:
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. For most users, this new feature is actually very convenient. If you want to control the update process,...
