cannot convert parameter 2 from 'char [80]' to 'LPWSTR'

[sabeesh]

Hi,
I am using QT-4.3 and Using Visual Studio-2005 for compiling. I need to find the Web camera in windows. For that I use this command,

char szDeviceName[80];
char szDeviceVersion[80];
 
for(int iPos = 0; iPos<2; iPos++)
{
         if (capGetDriverDescription( iPos,  szDeviceName,  sizeof (szDeviceName), 
            szDeviceVersion, 
            sizeof (szDeviceVersion)
        )) 
 
    qDebug()<< " driverName " << driverName;
}

char szDeviceName[80];
char szDeviceVersion[80];

for(int iPos = 0; iPos<2; iPos++)
{
         if (capGetDriverDescription( iPos,  szDeviceName,  sizeof (szDeviceName), 
            szDeviceVersion, 
            sizeof (szDeviceVersion)
        )) 

    qDebug()<< " driverName " << driverName;
}

To copy to clipboard, switch view to plain text mode 

when I try this, at the time of compiling VS-2005 display an error like this,

'capGetDriverDescriptionW' : cannot convert parameter 2 from 'char [80]' to 'LPWSTR'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

Please help me to solve this probs
