do you know what the _T() macro does ?

it simply prepends a L in front of the string (because you're supposed to pass it a literal string, not an integer) if UNICODE is defined, and does nothing otherwise.

Oh no. Prepends nothing in his case.

You're trying to do a pretty weird thing.
Since your application is not set as a UNICODE build, the macro _T expands to nothing and you'll get s1 = (2193);
and this shouldn't ever compile.
BTW UNICODE value for down arrow is 0x2193, i.e. 8595.

You can use of SHFileOperation or rename.

I used the code below but it does not rename the source file even it creates another file (spacifies in To).

SHFILEOPSTRUCT sfo; <br />
	ZeroMemory ( &sfo, sizeof (SHFILEOPSTRUCT)); <br />
	sfo.wFunc = FO_RENAME ;<br />
	sfo.pFrom = _T("g:\zz.txt\0");<br />
	sfo.pTo = _T("g:\pp1.txt\0");<br />
	SHFileOperation(&sfo);

i have a

CSocket SomeSocket;

variable declared globally in a "one.h" file.I have inlcuded this one.h in one.cpp as

#include "one.h"

I used this SomeSocket in another two.h files where i have included the file

#include "one.h"

now i get a linker error stating

two.obj : error LNK2005: "CSocket SomeSocket" (?xst@@3UGlobals@@A)
already defined in one.obj

what was the mistake.

You need to put include guards in your header file:

#ifndef YOURFILE<br />
#define YOURFILE<br />
<br />
// Code here<br />
<br />
#endif

(replace YOURFILE by something unique, like the file name).
You could also use #pragma once for microsoft compiler.

you have to declare it extern inside your include file (i.e. "one.h")

extern CSocket SomeSocket;

and then define once inside a single source file (e.g. in your "one.cpp").

CSocket SomeSocket;

The mistake is in your include file: as it stands CSocket SomeSocket is defined in multiple source files.

CPallini has given you the correct answer.

But I see this mistake a lot with novice programmers.

The linker is complaining because (as it says) you have two instances of SomeSocket.

Before the compiler attacks you "one.c" file, a preprocessor attacks it, and processes the includes.

An easy exercise for you: remove the #include from one.c, and cut and paste the whole of one.h into the top of one.c.
Do this for two.c. Now have a lightbulb moment as you realise what the linker is telling you.

Insert a Timer function in which the bar gets updated. 100ms is a nice value.:->

AFAIK yes, it is possible, but how accurate it is... depends on code.

You can create a function in the modeless dialog's class that updates the progress bar's state. Call that function at various points in your process.
