how to : use winsock

I'm a newbie in coding VB and my english is not good. I have some questions, plz help me :
I want to make a program that run in a network which have some computers like this :
1) The computer of boss.
2) The secretary's computer.
3) Some computers of the workers.
- When the office receive a letter or a mail, the secretary will scan it (if it's a letter) or copy and paste the text to Microsoft Word (if it's a mail) and send to the boss. The boss will view and sign "accepted " then send back to the secretary. After that ,the secretary can send that document (file .pdf or file .doc) to other computers (workers' computer ).
- OR the secretary write a document and send it to the boss. The boss edit it end send it back to the secrectary . After that it will be sent to other computers.
Can I use winsock to transfer file ? How can I make a signature for the boss which can not be faked ? How to arrange documents in a scientific way.

All that can be done in VB quite easily.
Well a signature pure to the boss only -- also possible but someone could easily fake it no matter how perfect you make it, if someone wants to, they can.

An explanation is unworthy since you asked 5 questions all which are quite complicated.
If you do not understand how to Winsock in VB then google for some tutorials.

Or, ask 1-2 questions at a time instead of 5.

If you wait long enough I am going to write a tutorial for Winsock in C++.

If I understand you correctly, you could do all that with email. Unless the document requires a real signature. In that case, the boss would have to create a hard copy of the document, sign it, rescan it and then return it to the secretary.

If you can get by with an image of the signature, then the boss could edit the document and paste in a .jpg (or whatever) image of his/her signature before returning the document to the secretary. If access to the boss's pc is restricted properly, the signature image should be secure.

thank for your advice Halsafar ! I just want some codes that can send file to another computer ( every types of files, and the size up to 100 MB ). It can run on every computer , don't have client or server. And it sounds "beep" when receive file. Can u help me ?
thank you ccoder ! But login and download file from a mail server is less safe and take more times than internal transfering files . And an important thing is it is not right that all the computers can connect to internet.

From what you are saying, I have to assume that your company does not have its own internal mail server like MS Exchange, etc. Then yes, it isn't as safe as a file transfer.

On another note, I would display a message box rather than sound a beep when the computer recieves a file. If someone is away from their desk when the file arrives, they won't hear the beep.

I don't know about "MS Exchange". Maybe I will find more inforamtion about it.
"sound a beep " is just an sample. Its easy to edit it and replace with a msgbox. So I will thank u much if u help me some code than finding my mistake .

Hopefully you will find this handy...Winsock
