It'll check whether a webpage is completely loaded or not in the active Internet Explorer.

NEED the latest COM Standard Library.

Code:
; Run, iexplore.exe http://www.google.com/
MsgBox, % IEReady()
Return

IEReady(hIESvr = 0)
{
   If Not   hIESvr
   {
      Loop,   50
      {
         ControlGet, hIESvr, hWnd, , Internet Explorer_Server1, A ; ahk_class IEFrame
         If   hIESvr
            Break
         Else   Sleep 100
      }
      If Not   hIESvr
         Return   """Internet Explorer_Server"" Not Found."
   }
   Else
   {
      WinGetClass, sClass, ahk_id %hIESvr%
      If Not   sClass == "Internet Explorer_Server"
         Return   "The specified control is not ""Internet Explorer_Server""."
   }

   COM_Init()
   If   DllCall("SendMessageTimeout", "Uint", hIESvr, "Uint", DllCall("RegisterWindowMessage", "str", "WM_HTML_GETOBJECT"), "Uint", 0, "Uint", 0, "Uint", 2, "Uint", 1000, "UintP", lResult)
   &&   DllCall("oleacc\ObjectFromLresult", "Uint", lResult, "Uint", COM_GUID4String(IID_IHTMLDocument2,"{332C4425-26CB-11D0-B483-00C04FD90119}"), "int", 0, "UintP", pdoc)=0
   &&   pdoc && pweb:=COM_QueryService(pdoc,IID_IWebBrowserApp:="{0002DF05-0000-0000-C000-000000000046}")
      Loop
         If   COM_Invoke(pweb, "ReadyState") = 4
            Break
         Else   Sleep 500
   COM_Release(pdoc)
   COM_Release(pweb)
   COM_Term()
   Return   pweb ? "DONE!" : False
}

Great work. I've added it to the FAQ:
Quote:
How to detect when a web page is finished loading?

With Internet Explorer, perhaps the most reliable method is to use DllCall and COM as demonstrated at http://www.autohotkey.com/forum/topic19256.html. On a related note, the contents of the address bar and status bar can be retrieved as demonstrated at http://www.autohotkey.com/forum/topic19255.html.

Im relativley new to ahk, so maybe im doing something wrong. I copied your code and created a new ahk file on my desktop. Then copied the CoHelper code and saved it as CoHelper.ahk also on my desktop. I then double click on the first file to run it and I get this error:
Error at line 64 in #include file "C:\Documents and Settings\bdmock\Desktop\CoHelper.ahk".
Line Text: :
Error: The leftmost character above is illegal in an expression.
The program will exit.

I have been charged with automating the test order process on one of my companies websites. I have started working on this already and found that the only way to have my script wait for the page to load is to use ImageSearch. This process works so far but this sounds like it will work more efficiently.
What am I doing wrong? How will this work within another script?

Thank you in advance.

Just a guess: Wordwrap error while copying?

I recopied the code for both programs and still got the same error. I tried copying the code into notepad, textpad, and word all with the same result.

Am I using it properly? Do I need to assign a hotkey to it or call it from another script? It sounds like it is supposed to throw a MsgBox when the page under the mouse is finished loading, when I start the script my mouse is on the desktop. Could this be the problem? If so, how do I start the script while the page is loading?

by the way, line 64 is:

Unicode2Ansi(ByRef wString, ByRef sString, nLen = 0)
{
pString := wString + 0 > 65535 ? wString : &wString
If !nLen
nLen := DllCall("WideCharToMultiByte", "Uint", 0, "Uint", 0, "Uint", pString, "int", -1, "Uint", 0, "int", 0, "Uint", 0, "Uint", 0)
VarSetCapacity(sString, nLen)
DllCall("WideCharToMultiByte", "Uint", 0, "Uint", 0, "Uint", pString, "int", -1, "str", sString, "int", nLen, "Uint", 0, "Uint", 0)
}

Next guess: Try updating your AutoHotkey to the latest version...

That worked! I was still using the version I downloaded last year around september because I do not have admin rights on my computer so I had to call a helpdesk tech over to install the newer version.
Thank you for your help. Next time I have problems like this I will make sure Im using the current version before wasting everyones time in the forum.
Thanks again.

No prob. You can download the zipped version of AutoHotkey too, for your portable-AutoHotkey-pleasure Wink
