用GetLogicalDriveStrings获取磁盘列表

TCHAR szDriverBuffer[512];

CString csDriver;

DWORD dwLength = GetLogicalDriveStrings(IN 512, OUT szDriverBuffer);

// 执行后，在szDriverBuffer中存储的盘符数据格式：

// C:\<nul>D:\<nul><nul>

TCHAR *lpDriverBuffer = szDriverBuffer;

while (*lpDriverBuffer != NULL)

{

csDriver = lpDriverBuffer;

lpDriverBuffer = lpDriverBuffer + csDriver.GetLength() + 1;

//cout<<csDriver<<endl;

}
