Windows mobile 注册表中读取一个键值

guowee

最近再写程序的时候，想读取注册表中一个键值的数据。可是查了很多资料，都不能取到注册表中键值。
最后终于搞定了。下面是代码：
 
void GetInternalPictureLocation(TCHAR *outBuffer)
{
    LRESULT lr = E_FAIL;
    HKEY hKey = NULL;
    DWORD dwValueDataLen = 123456;
    BYTE *dwValueData = (BYTE *) LocalAlloc(LMEM_FIXED, dwValueDataLen);
    DWORD dwValueType = 0;
    LONG rc = NULL;
    rc = RegOpenKeyEx(HKEY_LOCAL_MACHINE, L"\\System\\Pictures\\Camera\\OEM\\PictureLocation",0,0,&hKey);
    if(rc==ERROR_SUCCESS)
    {
        lr = RegQueryValueEx(hKey,TEXT("Internal"),NULL,&dwValueType,(LPBYTE)dwValueData,&dwValueDataLen);
        *outBuffer = TEXT('\0');

        lstrcat (outBuffer, TEXT("\""));
        lstrcat (outBuffer, (LPTSTR) dwValueData);
        lstrcat (outBuffer, TEXT("\""));
        RegCloseKey(hKey);
    }
}
