This is perhaps not what you want to hear, but I recommend using the browser extension Last Pass for auto-log-ins: it is specialized for this task and will always perform better than AHK. Unless you need to integrate this into your program or something.

I don't know how Last Pass would necessarily perform better than AHK unless you're taking about using it on a non-IE browser. Here's a solution using the latest version (AHK_L) when using Internet Explorer and that page is open and is the active page:

Code:
pwb :=   IE_Get()
pwb.document.all["txtUserid"].value :=   << your username here >>
pwb.document.all["txtPassword"].value :=   << your password here >>
pwb.execScript["javascript:document.frmServiceDesk.submit();"]

IE_Get(hWnd="") {

   static   IID :=   "{332C4427-26CB-11D0-B483-00C04FD90119}"

   if   !hWnd
      ControlGet, hWnd, hWnd, , Internet Explorer_Server1, ahk_class IEFrame
   return   ComObj(9,ComObjQuery(Acc_ObjectFromWindow(hwnd),IID,IID),1)
}

Acc_Init() {
   Static   h
   If   !h
      h :=   DllCall("LoadLibrary","Str","oleacc","Ptr")
}

Acc_ObjectFromWindow(hWnd, idObject = -4) {
   Acc_Init()
   If   DllCall("oleacc\AccessibleObjectFromWindow", "Ptr", hWnd, "UInt", idObject&=0xFFFFFFFF, "Ptr", -VarSetCapacity(IID,16)+NumPut(idObject==0xFFFFFFF0?0x46000000000000C0:0x719B3800AA000C81,NumPut(idObject==0xFFFFFFF0?0x0000000000020400:0x11CF3C3D618736E0,IID,"Int64"),"Int64"), "Ptr*", pacc)=0
      Return   ComObjEnwrap(9,pacc)
}

I'm sure AHK can do it very well technically. But Last Pass does it all automatically and can still get the forms if the page changes (normally it can, at least). I was also assuming the OP wasn't using IE. And it is extremely convenient, because you won't need to do anything, just click the Save Password button that pops up (or whatever it's called). Whenever you go to the log-in page afterwards, you don't even need click "log in": all is done automatically.

Thanks, however I'm looking for a way to update information and download files remotely. I think cURL does something like that if i'm not mistaken.
After some digging I found out how to use GET method, to retrieve raw html of a page

Code:
WebRequest := ComObjCreate("WinHttp.WinHttpRequest.5.1")
WebRequest.Open("GET", "http://www.google.com")
WebRequest.Send()

Gui, Add, Edit, x12 y10 w710 h320 , % WebRequest.ResponseText()
Gui, Show, w735 h350, html page

ObjRelease(WebRequest)
return

GuiClose:
ExitApp


What I can't find is a decent explanation/examples of how POST should be used. Can anyone try to help me understand this?
Thanks :oops:

@sinkfaze - the return from ComObjEnwrap needs to take ownership of the pointer so that you're not leaking com objects:
Code:
Return   ComObjEnwrap(9,pacc,1)

Also, to be extremely picky, the IE_Get function is returning a window object, not a webbrowser object.

It might help to search the web with the keywords, WinHttp.WinHttpRequest Post.

For example, I found some relevant topics. The COM syntax is almost the same so you wouldn't have a problem translating them.
IWinHttpRequest::Send method wrote:
Code:
// Instantiate a WinHttpRequest object.
var WinHttpReq = new ActiveXObject("WinHttp.WinHttpRequest.5.1");

// Initialize an HTTP request. 
WinHttpReq.Open("PUT", "http://postserver/newdoc.htm", false);

// Post data to the HTTP server.
WinHttpReq.Send("Post data");

Thanks, that cleared some things up for me :D
So I'm trying to login to gmail, here's the code that I have so far:
Code:
URL = https://accounts.google.com/ServiceLoginAuth
login := "Email=" . user . "&Passwd=" . pass
WebRequest := ComObjCreate("WinHttp.WinHttpRequest.5.1")
WebRequest.Open("POST", URL, false)
WebRequest.SetRequestHeader("Content-Type", "application/x-www-form-urlencoded")

WebRequest.Send(login)

Gui, Add, Edit, x12 y10 w710 h320 , % WebRequest.ResponseText()
Gui, Show, w735 h350, html page

ObjRelease(WebRequest)
return

GuiClose:
ExitApp


it returns the same login page html when I run it, only this time my username is in the username field. What am I doing wrong here, why isn't it accepting my password?

Here's my latest attempt:
Code:
URL := "https://accounts.google.com/ServiceLogin?service=mail&passive=true&rm=false&continue=https://mail.google.com/mail/ca/&ss=1&scc=1&ltmpl=default&ltmplcache=2"
login := "Email=" . user . "&Passwd=" . pass
WebRequest := ComObjCreate("WinHttp.WinHttpRequest.5.1")
WebRequest.Open("POST", URL, false)
WebRequest.SetRequestHeader("Content-Type", "application/x-www-form-urlencoded")

WebRequest.Send(login)

URL := "https://mail.google.com/mail/ca/?shva=1#inbox"
WebRequest.Open("GET", URL)
WebRequest.Send()

Gui, Add, Edit, x12 y10 w710 h320 , % WebRequest.ResponseText()
Gui, Show, w735 h350, html page

ObjRelease(WebRequest)
return

GuiClose:
ExitApp


It's not working :(
