BOOL StateChange(DWORD NewState, DWORD SelectedItem,HDEVINFO hDevInfo)

}

// Call the ClassInstaller and perform the change.
// This may take a while !
if (!SetupDiCallClassInstaller(DIF_PROPERTYCHANGE,

}

return TRUE;
}
BOOL IsClassNet( GUID * ClassGuid )
{
#define MAX_NUM 50

HKEY hKeyClass;
LONG lRet;
char ClassType[MAX_NUM];
char NetClass[MAX_NUM] = "Net";
DWORD dwLength = MAX_NUM,dwType = REG_SZ;

if (hKeyClass = SetupDiOpenClassRegKey(ClassGuid,KEY_READ))
{
lRet = RegQueryValueEx(hKeyClass, TEXT("Class"), NULL,
&dwType, LPBYTE(ClassType), &dwLength);
RegCloseKey(hKeyClass);

if (lRet != ERROR_SUCCESS)
return FALSE;

if (!strcmp(ClassType,NetClass)) // if they are the same;
return TRUE;
}

return FALSE;
}
能不能帮忙解释一下这是什么意思呢 谢谢了
