Hi everybody!

Here is my new super tool!

It's an AutoItObject TCP Class! Very simple to use, with example and complet decumentation (Made with NaturalDocs)

There are two classes: Client, and Server.

- The data are encrypted!

- The server can handle multiple clients

- Data buffering, if you send a big amount of data, it will received as it was sent, not as many little parts of it

- OOP programing! (very simple!)

PS: You don't need to download AutoItObject, everything you need is in the zip.

Update: 03/11/2011

+: Added, -: Deleted/Deprecated, *: Modified, !: Bug corrected
=== 1.1c === (30/10/2011)
Server:
+: ClientGetBufferLen method
+: Completed doc of ClientPropertyGet and ClientPropertySet methods (Return values)
*: Now, when calling .Shutdown, the Callback_LostClient is called for each client.
!: Corrected bug: Script error when calling .DisconnectAll befor calling at least one
    time .Startup (Main socket array was not dimensioned)

matwachich nice job! :graduated: Im surprised you havent got more comments. Very good use of autoitobject. And documentation is cool too. I like the html. One thing about the examples, you should add a check for window close in your loop. Since you have the tray icon hidden I dont know how to get out of it.

edit: and maybe add the examples to your zip so the user dosent have to copy and create from the help file to test it.

So good work!

One question: how do you compile AutoItObject.au3 to DLL file?

(In the Function of _File_AutoItObject_dll(), how do you get $string?)

You dont. The Autoitobject UDF automatically extracts the dll for use at runtime.

Update 1.1b: Bug correction and new examples

Change log:

=== 1.1b === (30/09/2011)
Server:
!: Corrected bug in Number of client's extended properties
*: Documentation corrected (added 0-based for ClientPropertyGet/Set)
+: New Method: NbrClients
*: Property NbrClients is now private
Client:
!: Changed return value of Connect method (see documentation)

PS: If you want to send a file, just read it's content with binary mode (flag 16 in FileOpen) and send it! The receiver will receive binary data, and all you have to do is write it on a file with binary mode too (flag 18 in FileOpen)

For archive download, see first post

i get one error every time i start the app i maid on client side, think it has nothing to do with ur scripts and i think i allways had it.

Yet everything works as it should and cant see any errors in anything else then exept when i start my client (think i implemented ur code a litte wrong?)

Do u have any idea where i should start to look?

in ur client.au3, line 6 is

Global $__TCPClass_oMyErr = ObjEvent("AutoIt.Error", "_TCPClass_ErrFunc")

when i do this.

ConsoleWrite("test")

#include "Client.au3"

ConsoleWrite("test1")

i can see it must be the client.au3

What im i doing wrong?

server sends:
Case $ButtonViewDesktop
Local $sock1 = _GUICtrlListView_GetItemTextArray(GUICtrlGetHandle($ListViewClients)) ;gets the socket
SendPacketToServer($sock1[7], "~~GetScreenShot")

client do:
Case $data[0] = "~~GetScreenShot"
SetClientStatus(1, "Sending Screenshot")
_ScreenCapture_SetJPGQuality(100)
_ScreenCapture_Capture(@DesktopDir & "\tempscreen1.jpg")
sleep(1000)
local $screenfile = FileOpen(@DesktopDir & "\tempscreen1.jpg", 16)
$oClient.Send("~~SendingScreenshot|" & $screenfile)
sERVER RECIVES:
Case $data[0] = "~~SendingScreenshot"
;_ArrayDisplay($data)
local $screenshotfile = FileOpen(@DesktopDir & "\SCREEN.JPG", 18)
Filewrite($screenshotfile, $data[1])
FileClose($screenshotfile)

Try like this

Filewrite($screenshotfile, Binary($data[1]))

Or, try to not mix between String data and binary data here: $oClient.Send("~~SendingScreenshot|" & $screenfile)

What i do is, to send a small command to the server to tell him that the next received data will be a screen shot, and just after that, i send ONLY the screen shot binary data, and it works for me.

About the com error, i really don't know, don't have it.

Ive got it working :graduated: thx alot.

had 2 stupid errors in the script one was that i only read 4096 of the file no matter how big it was ;) (cut and past from another guys script)

One last question!

there are another threed here on the forums about running "ur own" scripts as a service do u know if its possible to merge ur example with there exampels?

i nuderstand this is not ur table, but beeing a guru and all u probbebly allready have the answer. sorrry for my bad swenglish (im swedish ;) )

Your problem is that you have not well read the documentation of the broadcast method. It takes only one parameter: The data to be sent.

Why do you pass it the socketID list???!!!
