    <p>I am at the server side, and receive Image as binary stream from a client, the server Detect that we deal with image and the size in bytes arrived to the server via previous message from the client!</p> <p>the server have a size of the file supposed to read, and stream...Eter to while loop... read from the Client Stream, and immediately write to the file, and reset the buffer to read<br> Everything Work wellm until Some kilobytes before the end of the file some kilobytes don't writen to the file... I get smaller file on the server library...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
