Can anyone make this clearer using the above function as example.

char deviceBuffer[1024];
DWORD bufferLength = sizeof(deviceBuffer);
  
LONG defaultDevice = ITCSCAN_GetDefaultDevice(deviceBuffer, &bufferLength);

Code does not work.

LPTSTR szBuffer = NULL;
DWORD dwLen = 0;
ITCSCAN_GetDefaultDevice(NULL,&dwLen)
if(0 < dwLen)
{
	szBuffer = new TCHAR[dwLen];
	ITCSCAN_GetDefaultDevice(szBuffer,&dwLen);
	
	//Do something with buffer...
	
	delete [] szBuffer;
}

Do you have any experience with "wifstream"? Could you share it with me?

void main( void )
{    
    wofstream out("c:\\data.dat", ios::binary);    
    out << 123;    
    out.close();          
    
    wifstream in("c:\\data.dat", ios::binary);    
    int x;    
    in >> x;    
    in.close();
}

But your sample saved it as "1".

But "Write" function can only write string to the file.

ofstream out("c:\\data.dat", ios::trunc | ios::binary);        
int y = 1234;
out.write((const char *) &y, sizeof(y));
out.close();

But "read number" from binary file still does not work.

ifstream in("c:\\data.dat", ios::binary);        
int x;        
in.read((char *) &x, sizeof(x));
in.close();

IS there a way to convert a TCHAR string to integer number...

netsh interface ip set address "XXXX" static 192.168.18.183 255.255.255.0 192.168.18.1 1<br />

netsh interface ip set DNS   "XXXX" static 211.161.192.1<br />
netsh interface ip add dns   "XXXX" 211.161.192.73 index=2<br />
