I've read this thread, and I don't see any justification for wanting to put the pages in different tabs. Specifically, there is no mention of user interaction. Assuming that there is no user involvement and that you are simply after information on those pages, I think you would be better off creating an IE instance for each page to which you'd like to navigate. For example, an array of IE instances which (eventually) should run hidden. However, there is a second problem, which is already evident in your code, and that is that you are having a significant problem determining when pages are ready. This is, in general, quite a difficult issue. I think it would be far easier for you to spawn a different process for each page you'd like to load so that it can be dealt with separately. However, doing this with 10 pages or so can be a massive hit on the CPU, so I don't recommend this route. Parallel processing of pages is really messy. Unless you have a REALLY SPECIFIC reason for needing the parallel aspect, your posted code implies that you are doing background processing. That being the case, you could just as well process each page one at a time (which also reduces the chance that the remote site will ban you for robotic access of their pages). So you could have the original IE for your starting page, and then create a second IE for your array of links (so that you can get back to your original IE when done with processing said array). Now process each link one at a time (taking into account what to do if you've gotten to some timeout limit and the page hasn't loaded).

From: AvWG on 11 Nov 2009 16:32 Hi Csaba, Thank you for your message. I've already done what you described. One Instance, two instances, 25 instances. But that's not the problem. One of the problems is that it is not possible to go to the 12th tab after creating 25 tabs (with ie VBScript) .The other problem: When I use something like sendkeys and end at the 12th tab, I don't get the source of that page. What I do get is the source of the very first page I need to start, with credentials in order to have access to that particular site. Manually on that page I can click on 'Source' in the menu and get the source I want... So no methodes to freely move between tabs and not getting the right source dump....

I think Csaba Gabor is saying the same thing I suggested a few days ago: Don't use tabs! Navigate in a single window to each page, one at a time. Then you only have one page loaded at a time and the source code is available.

What makes it compelling to create any tabs whatsoever? I'm not saying there couldn't be a reason, but without guiding our thinking a bit, it is hard to wrap our heads around why. Specifically, the internet world existed pretty well before tabs came along. They did so as a user convenience rather than a user necessity. So I would think you have to be doing something pretty darned unusual to be requiring tabs. > The other problem: When I use something like sendkeys and end > at the 12th tab, I don't get the source of that page. What I do Oh, and that's the other thing. You should really be avoiding send keys, when at all possible. It is only a method of last resort, and it is really easy to mess up doing the kinds of things that you are doing (as you have come to realize). Without looking more at your specifics, my first inclination is to think that you have timing issues. One possiblility for you is to really slow the send keys down (if your architecture doesn't permit this, the timing issues become much more probable) so you can see it as it happens. How do you avoid send keys? The answer is to fill out the form on the page (for example, something like: ie.document.getElementById("myId").value = "myEntry" or var body = ie.document.body body.getElementsByTagName("INPUT")(0).value = "myEntry") You can direct links and targets to a specific window by setting their target attribute to the name of the window or frame in question. Oh, and yes, mayayana expressed both the principle of not using tabs nor using send keys much more succinctly in his Nov 8 post. > get is the source of the very first page I need to start, with > credentials in order to have access to that particular site.

Hi, I've done all, with and without tabs. And in both cases I can't get the "same" source of a page, manually vs vbscript. So, for me, the problem is that vbscript can't do the job for me and I doubt another language can... I believe the problem is the internet.application-object does not provide the right "tools" Btw: for my current job I automate every thing with vbscript and till now there was little I couldn't handle.... :-( Andr� "Csaba Gabor" <danswer(a)gmail.com> schreef in bericht news:0ddc3d94-fccc-4a53-a9f6-b4aaa5baba80(a)d5g2000yqm.googlegroups.com...
