For me work fine on WinXP Professional SP3. I saw that you use Win Vista, maybe this is the problem. Please tell me what you what to do and maybe I can help you? You want just to get the yahoo avatar and put in your GUI?

If you're trying multi-threading then you can forget it.

[monoceres]

AutoIt is not thread-safe so pointing new threads to autoit callbacks will sooner or later make code collide and crash pretty hard.

You'll have to rethink your logic or implement the thread in a different language.

[Yashied]

Alternatively, you can use multiple processes.

Personally, I am doing just that.

[jvanegmond]

Actually, all you're doing is making an InetGet call which can be done async. Just look at the helpfile for InetGet.

And if you install the Beta (>= 3.3.1.0), you can have multiple downloads with the "background" parameter

My progam is get avatar and check that yahoo's invisible or offline. But it still take the long time have a response from sever. Thus, i want to create thread to do that thing. The program don't need to wait response from server. it can do some thing else.

This is my soft.

I repeat, you can create a separate process for this and use WM_COPYDATA for communicate between processes. Multithreading will not work in AutoIt. He does not designed for this.

CreateThread Function

Creates a thread to execute within the virtual address space of the calling process.

To create a thread that runs in the virtual address space of another process, use the CreateRemoteThread function.

But in Autoit that is not possible except by using

Assembly language Through the Autoit language

Such an example in this topic

Execute in a different thread

http://www.autoitscript.com/forum/index....&st=0&p=686626&fromsearch=1&#entry686626

in Autoit Function does not work

properly as this example

#include <GUIConstantsEx.au3>
GUICreate("CreateThread") 
$Button = GUICtrlCreateButton("CreateThread", 10, 30, 150)
 GUISetState()      

$i1 = 0
While 1
$i1 += 1
ToolTip("LOOP1 = " & $i1,200, 100)
$msg = GUIGetMsg()
Select
Case $msg = $GUI_EVENT_CLOSE
ExitLoop
Case $msg = $Button
$handle = DLLCallbackRegister ("ThreadProc", "int", "ptr")     
$Return = DllCall("Kernel32.dll","hwnd","CreateThread","ptr",0,"int",0,"ptr",DllCallbackGetPtr($handle),"ptr",0,"int",0,"ptr*",0)
$handle = $Return[0]
$lpThreadId = $Return[6]
EndSelect
WEnd




Func ThreadProc($lpParameter)
$i2 = 0
While 1
if GUIGetMsg() = $GUI_EVENT_CLOSE Then Exit
$i2 += 1
ToolTip("LOOP2 = " & $i2,300, 100)
WEnd
EndFunc
