I am working on an app where I need to display the file system format of the SD card. Since I couldnt find any Qt API’s for it, I choose a windows API GetVolumeInformation and did it as follows:
TCHAR volumeName[MAX_PATH + 1] = { 0 };
TCHAR fileSystemName[MAX_PATH + 1] = { 0 };
DWORD serialNumber = 0;
DWORD maxComponentLen = 0;
DWORD fileSystemFlags = 0;
LPCWSTR path = deviceData->m_strPath;
if (GetVolumeInformation(
path,
volumeName,
ARRAYSIZE(volumeName),
&serialNumber,
&maxComponentLen,
&fileSystemFlags,
fileSystemName,
ARRAYSIZE(fileSystemName)))
{
qDebug()<<fileSystemName[0];
qDebug()<<fileSystemName[1];
qDebug()<<fileSystemName[2];
qDebug()<<fileSystemName[3];
qDebug()<<fileSystemName[4];
}
path indicates the SD card path and when I run the app, it throws the following error:
“cannot convert from ‘QString’ to ‘LPCWSTR’”. Where am i making a mistake??? Please help!!
