There is no such thing, AFAIK neither %w nor %ws are standard replacement markers. Are you thinking maybe of %ls? That inserts a Unicode string, zero terminated.

i went across this printf formatting options and on some googling i came across that it is ANSI C formatting options which specifies the width of string also.
i have seen some MS samples which are displaying this output format.

but the probelm is i do not know the details of this thing.

Dear All,
I am developing an application in MFC VC++ Version 6.0 for Windows 2000.
I want to check existence of a file in my application eg. i want to check whether c:\rohit\abc.txt exists of not
Can any body please tell me the API for this ?
Feel free to ask any further queries in this regards,
Thanks

You can do it via FindFirstFile
Specify in the first parameter file name you need to verify
You will get as result INVALID_HANDLE_VALUE if file does not exist
Otherwise, you will get a valid handle & you must close it with FindClose function

Thanks max,
That was very useful. i got the following sample code from msdn . And it solved my problem too!
define _WIN32_WINNT 0x0400
#include "windows.h"
int
main(int argc, char *argv[])
{
WIN32_FIND_DATA FindFileData;
HANDLE hFind;
printf ("Target file is %s.\n", argv[1]);
hFind = FindFirstFile(argv[1], &FindFileData);
if (hFind == INVALID_HANDLE_VALUE) {
printf ("Invalid File Handle. Get Last Error reports %d\n", GetLastError ());
} else {
printf ("The first file found is %s\n", FindFileData.cFileName);
FindClose(hFind);
}
return (0);
}

if(0xFFFFFFFF !=GetFileAttributes(filename))
/*file exists*/
else
/*does not*/

if (_access("c:\\rohit\\abc.txt", 00) == 0)
{
// file exists

You can use PathFileExists(...) from the shell api
if( PathFileExists( strPath ) )
{
}
|
|
|
|
|
_access()
GetFileAttributes()
CFile::GetStatus()

I had read about a utility which retrieves files deleted by Shift+Del...
I think it was one of Norton's utilities.
The theory used there was that when files are deleted by the user, they don't actually go off the disk right away but the sections of the disk are marked as deleted. The utility read through these sections and retrieves the data.
Just wondering if (hoping that) you might have any additional info.

Other than the one link no. I beleive that is what the source does from the link however.

Where is there an accessible copy of the MFC FAQ ?
I was trying to point someone to it yesterday and I could not find it online either at Code Project or externally.

I am writing a class for serial port communication.
It always returns FALSE when I set commport state by calling
win32 api SetCommState.
following is some code from my class:
//code starts here
//m_hComm is an effective handle to commport
m_dcb.DCBlength= sizeof(DCB);
m_dcb.BaudRate =nBaud;
m_dcb.ByteSize = nDataBits;
m_dcb.Parity =nParity ;
m_dcb.StopBits =nStopBits;
m_dcb.fBinary=TRUE;
m_dcb.fDsrSensitivity=FALSE;
m_dcb.fParity=bParity;
m_dcb.fOutX=FALSE;
m_dcb.fInX=FALSE;
m_dcb.fNull=FALSE;
m_dcb.fAbortOnError=TRUE;
m_dcb.fOutxCtsFlow=FALSE;
m_dcb.fOutxDsrFlow=FALSE;
m_dcb.fDtrControl=DTR_CONTROL_DISABLE;
m_dcb.fDsrSensitivity=FALSE;
m_dcb.fRtsControl=RTS_CONTROL_DISABLE;
m_dcb.fOutxCtsFlow=FALSE;
m_dcb.fOutxCtsFlow=FALSE;
BOOL bRet= ::SetCommState(m_hComm, &m_dcb);
if(!bRet)
{
CloseHandle(m_hComm);
MessageBox(NULL, "Set comm state error!", NULL, MB_OK);
return FALSE;
}
//code ends here
The bRet of above is always FALSE.How I can call SetCommState Successfully?
I need your help. Thanks.

Shouldn't it be SetCommState, not ::SetCommState?
Cheers,
Fredrik
