Reading and writing singleSRC or uuid (binary data)

[infomiquel]

I'm getting uuid from FilesModel class (reading table tl_files) and trying to write in singleSRC column in tl_news (using NewsModel class). But the result is different:

In tl_files, the value for uuid is something like: 0x5ec7706ee70211e69c7d00505694153
But in tl_news, the value writed for singleSRC is something like: 5ec7706e-e702-11e6-9c7d-00505694153

Please, how could I read and write this value properly?

Something like this is not working:

$objNews->singleSRC = $arrFiles[field_for_uploading_file][uuid];

Finally, I think this is working...!

$objNews = new NewsModel();
$objFile = new FilesModel();
$objNews->singleSRC = $objFitxer->findById($arrFiles[picture][uuid])->uuid; // 'picture' is the name of the form field for uploading a file

Good night!
