Get Firefox URL?
Learner 24 July 2008 18:42:25
	Does anyone know a way to get the URL from the Firefox Address Bar? I've seen similar questions archived in Google Groups but no definite answer with any example code. There MUST be a way. I've tried various window-spying apps but none of them have shed any light on it. All I've found is that the Firefox Address Bar seems to be some sort of custom control that the Win32 API can't touch.

	Hello I can suggest a way that is sure to work, but requires you to do some learning first: 1. Learn about plugin development for FireFox and how you can through an FF plugin get the address bar 2. From that plugin, establish IPC (interprocess communication) with your main application and pass to it the address bar URL.

	Oh, Alf, the OP didn't mention anything about writing any programs of any flavour, VB or otherwise, though he did mention "example code" (which could imply he may be able to write/assemble something in some language) His last reply is then confusing. Maybe his PC is controlled by a very tight IT department. Learner, unless you can enlighten those in the newsgroup about what you CAN do, this post could be a bit drawn out My gut feeling is that you may be looking in the wrong newsgroup for an answer, if it's not a Classic Visual Basic answer you require Argusy Alf P.

	I got curious about this and checked it out. (I also took pity because you seem to be attracting self-righteous open source people who are usually less interested in helping than they are interested in "setting others straight" about trivial issues like top-posting. I worked out the following that may be useful - Doable but not easy..... The main window - everything except title bar - is the parent window. In Spy++ the only child windows are the basic webpage view and the favicon 16 sq. px. window. In AccExplorer (Active Accessibility view) it turns out that the toolbar area is a tool bar object that has the same window handle as the parent. So the toolbar is not even a window, much less the location bar. You can get at it with AA if you want to, but it's not easy. You have to get the parent window that has "Mozilla Firefox", then get it's application child, which has the same name. Then you have to iterate children to find the child toolbar...then to that object's child combo box....and finally to that child's editable text object. Those are all aspects of one window with the same hWnd. If you want to use that method see here for sample code: http://www.jsware.net/jsware/vbcode.php3 Active Accessibility was designed for use by screen readers for the blind. It allows you to dissect nearly any window, but the AA system is a bit half-baked. It's tedious to use. On the bright side, if you need it for something specific, as you do, you can download the AA SDK, which includes AccExplorer (like Spy++). With AccExplorer you can see the window hierarchy and write your code based on that.

	* Learner:>> A program you're creating is going to be installed. Think about it.> Never run an app from a remote location, eh? Tsk. Think about it. Took you some time to come up with that rejoinder, didn't it? If you can run your own application from the network, but are forbidden to install it locally, you should talk with your IT department. Because then they have a security issue. Also, do heed the advice of "argusy": "... unless you can enlighten those in the newsgroup about what you CAN do, this post could be a bit drawn out" To help you solve your problem we need to know a bit more than you have provided so far. -- A: Because it messes up the order in which people normally read text.

	* Dag Sunde:> * Alf P. Steinbach:>> Read up on netiquette, please.> Eh?> Sorry Alf, but I was writing the above in defense/support of you. Oh. I was mislead by the phrase "And to you, xxx", which indicated that the text before that was addressed to someone else, i.e. me. And I have some times written things that some people have found to be rude -- I generally don't beat around the bush, but try to "think straight, talk straight", as one company's motto had it -- so it /could/ reasonably have been addressed to me, with a historical view. However, just in case some future employer skims Google's archives for old postings, I'm generally a very polite and nice person. To wit, I chose to not reply to the OP's last comment, which I think is in general the best response to such things. -- A: Because it messes up the order in which people normally read text.

Hmm ... Maybe some other info on the Window GetWindowContextHelpId GetClassName - we've tried that GetWindowLong - and look at GWL_STYLE and GWL_EXSTYLE There must be something (or some combination of things) that are unique about that Window

It doesn't show anything over Firefox, though, except for the extra title bar text. I've never understood why it's so hard to track Windows with the API, but it does seem to be limited. I posted the Active Accessibility info. because the only hWnd with Firefox's address bar is several levels up. AA identifies several controls but they're all within the same hWnd. I don't know what sort of API is inside AA's oleacc.dll, but it can read virtually anything if one is willing to write enough code.

It just> made sense to me that he's programming in Windows...he> wants a window property...he shouldn't have to get into some> 3rd-party API - and support files - to get that. A few incorrect assumptions: (1) that a pure general Windows approach is all that's required to interrogate a specific process' state, (2) that an application-specific approach is necessarily implied by using the access you have when running as a Windows application, (3) that Firefox' current URL is available as some kind of API-level window property. I'll refrain from listing the incorrect, wishful assumptions relating to motivations and so on. Incorrect assumption (1) is perhaps the easiest to comprehend the incorrectness of. Where do you draw the line about using application-specific knowledge? What is "allowed", in your view? And, importantly, can you demonstrate that that's enough for the Firefox URL? Note that /some/ application-specific knowledge is required however you do this, so you have some very arbitrary line drawn somewhere. "4-line cranky complaint about posting format" is actually his signature.> It seems to some it can be as annoying as top posting can be for others, but> I quess it's a purpose of it.> Signature or not, he put it into his post. As noted in another current c.o.m-w.p.win32 thread, where someone asked for permission to also use the signature, that signature has been adopted in at least one FAQ for how to post on certain groups, so it's not the case that people generally find it disagreeable. You, personally, disagree with my signature, fine. You label it is a cranky comment about posting format that I used instead of a proper reply, suppressing the fact that it's a signature and adding emotional content that you have no basis for inferring: that's absolutely not fine, that's intentional misrepresentation, unless you don't know what a signature is, which I don't believe. Having said that, back to the technical. Your idea of using accessibility was ingenious, and could have worked. However, it seems that Firefox 1.5* does not yet support Windows accessibility. At least, the Windows built-in "Joe" speaks only the window title and nothing of the contents (note to those who'd like to experiment: just using that thing messed up my toolbar icons...). I guess if disk access is prohibited (e.g., there is no local disk) then one way to proceed technically could be to infuse a DLL into the Firefox process. But the same thing could be achieved much more easily using a Firefox extension -- one would just have to convince the IT department to install that extension. I interpret the OP's reluctance to discuss these environmental issues as a sign that the question is really about cracking: there, now I've brought it out into the open. -- A: Because it messes up the order in which people normally read text. Q: Why is it such a bad thing? A: Top-posting. Q: What is the most annoying thing on usenet and in e-mail?

This is your subjective perception, as you admited yourself. And I believe your perception misleads you here. The OP didn't say nor "made clear" in any way he want to use some specific approach. He wrote "He can't" use approach suggested by lallous, because he "can't install anything on the PC". That's entire difference. If he really said he didn't want to install anything because trashing a system with third party components is a bad idea (and he would be right) the discussion would be over. Alf simply questioned inability of installing anything on a PC. Such inability is quite unusual thing and the OP didn't provide any reason for that. The form he used perhaps wasn't very fortunate but I wouldn't take it as rude. Nor, presumably, would anyone at comp.os.ms-windows.programmer.win32 where Alf is well known and respected contributor. But I can try to imagine how it could be received by someone at comp.lang.basic.visual.misc who saw his post for the first time. Still it's not the reason for giving him more rude responces nor even starting this off-topic conversation I made the mistake getting involved into. But that's my last off-topic reply in this thread. Signature or not, he put it into his post. I really don't know how to comment on this. I was certain you simply didn't notice it's a signature, otherwise you wouldn't comment it. -- 677265676F727940346E6575726F6E732E636F6D

	I got to playing around with the Active Accessibility approach. I don't know whether this is really a usable solution, but it's interesting. This is VB6 code. I guess it's about the same for VB5. This code would need some adjustments for your purpose, but this shows it can be done, at least. As for AA, it's in Windows at least as far back as Win98, but I'm not certain that it's always installed by default. ---------------------------------------------- Set the following code if a form named "F1": Private Sub bHook_Click() Hook End Sub Private Sub bUnhook_Click() UnHook End Sub Place 2 buttons, as named above, with captions "hook" and "unhook". Place a textbox named "Text1" ----------------------------------- In a module add this code (Reference to Accessibility needed in Project -> References. Lib. is oleacc.dll. Set "Show hidden Objects" in object browser if you want intellisense.) Public Const EVENT_MIN = 1& Private Const ROLE_COMBOBOX = &H2E& Private Const OB_ACCELERATORCHANGE = &H8012& Private Const SYS_ALERT = 2& Public Const WINEVENT_SKIPOWNPROCESS = 2& Public Const OB_REORDER = &H8004& Private Declare Function SetWinEventHook Lib "user32.dll" (ByVal eventMin As Long, ByVal eventMax As Long, ByVal hmodWinEventProc As Long, ByVal pfnWinEventProc As Long, ByVal idProcess As Long, ByVal idThread As Long, ByVal dwFlags As Long) As Long Private Declare Function UnhookWinEvent Lib "user32.dll" (ByVal lHandle As Long) As Long Private Declare Function AccessibleObjectFromEvent Lib "oleacc" (ByVal HWnd As Long, ByVal dwId As Long, ByVal dwChildId As Long, ppacc As IAccessible, pvarChild As Variant) As Long Private LHook As Long Public Sub Hook() Dim LRet As Long LHook = SetWinEventHook(SYS_ALERT, OB_ACCELERATORCHANGE, 0&, AddressOf WinEventFunc, 0, 0, WINEVENT_SKIPOWNPROCESS) End Sub Public Sub UnHook() Dim LRet As Long If LHook = 0 Then Exit Sub LRet = UnhookWinEvent(LHook) End Sub Public Function WinEventFunc(ByVal HookHandle As Long, ByVal LEvent As Long, ByVal HWnd As Long, ByVal idObject As Long, ByVal idChild As Long, ByVal idEventThread As Long, ByVal dwmsEventTime As Long) As Long Dim ObA As IAccessible Dim LRet As Long Dim V As Variant Dim s As String, s1 As String, sName As String On Error Resume Next Select Case LEvent Case OB_REORDER LRet = AccessibleObjectFromEvent(HWnd, idObject, idChild, ObA, V) If LRet = 0 Then F1.Text1.Text = "--" If CLng(ObA.accRole(V)) = 46 Then '-- combobox. If ObA.accName(V) = "Location" Then F1.Text1.Text = ObA.accValue(V) End If End If End If End Select WinEventFunc = 0 End Function ------------------------------- Open Firefox, run the project, click "Hook". Edit the Firefox location bar. You should see the text in Text1 keep up with any changes you make in Firefox's location bar.

	Did you give this a try by chance? I'm trying to accomplish the same thing so I'd be curious to hear about any success. Thanks. Learner wrote:> Thanks, I'll give it a go. Looks like it may be what I'm after!

	I tried iterating recursively through every child window of Firefox 3 (EnumChildWindows() in VC++), and getting the text (SendMessage( hWnd, WM_GETTEXT, MAXSIZE, (LPARAM)tWindowText)). Every @#$% window has no text (returns empty string). I'm a Firefox user, but in this respect IE is so much simpler. All I want is the current URL. Sigh...
