In our MOSS '07 site we have a page that contains just a Page Viewer web part in it that points to a site on another server. However, I've noticed that on that page (and any others that have a Page Viewer web part on it) our drop down menus and hover effects are super slow and completely max out the CPU on the visitor's computer (process is IExplorer.)
Through testing, I was able to determine that it doesn't matter what URL the web part is pointed to...just having the Iframe on the page seems to cause it (just setting the viewer to load Google's homepage--which is probably the simplest site I know--still causes the problem). If I go and remove the web part, the menus start functioning just fine again.
I attached a debugger to the process and stepped through the Menu_HoverStatic and called functions and it seems to have a hard time when assigning panel.scrollTop to zero in the PopOut_Show function.
Has anyone else noticed this? ...perhaps found a solution to it? I can't find where to edit PopOut_Show function on our server (I think it's a resource in one of the .NET DLLs) or else I'd just comment out that line as I don't think it's really important anyway...at least on our site.
I really like the ability to have web pages from another server hosted in our SharePoint site, but the performance on the hovers is agonizing... and, honestly, unacceptable. Depending on the resources of the user's computer, the hover effects can take 15 seconds to complete at times!!!!
Any suggestions would be really appreciated!
SharePoint's built-in JavaScript is probably making the browser wait until the IFrame within the Page Viewer Web Part has completely loaded. If you can see a status bar message that says "Please wait while scripts are loaded..." when you attempt to click on the page then that's definitely the problem.
Thank you for your reply. I was actually able to discover what the problem was (my appologies for not sharing it here with everyone when I did!)
The problem wasn't so much from having the IFRAME on the page, it was because I had set the zone to be 100% width and height. Because of a but in IE, trying to calculate the location of the dropdown was erroring (I don't remember what javascript function or call was exactly to blame, but I remember stepping through it with the debugger.) I believe it had something to do with "location offset" or something like that. My take at the time was that it was trying to position the dropdown menu on the screen, and the calculation for positioning it was failing.
To get around it, I had to set a javascript routine to programmatically set the height of the zone after the page loaded. Exactly setting the height prevented the dropdown problem in the menus. Of course, it wasn't ideal because if a user resizes the window, the IFRAME (or, more precisely, the zone it's in) doesn't resize with it. But, it was a suitable band-aid for the problem.
I'm hoping that IE 8 will fix this when it's released.

I've got a web application in which there are several XSS vulnerabilities on it, on the Profile Page for example there is a text box which is vulnerable to XSS along with the Messages Page. They both have text boxes yet when I add some XSS into the Profile Page, the pop up also comes up in the messages section and I can't figure out why. I've attached some screenshots for more information. If anyone can explain why this does this, I'd be very grateful.
The below Links are for visuals of the application
These are the source code images/files

You are inserting the saved data from this text box onto the messages.php page. If you right-click and inspect the "testtest" text, you'll notice a script was also added in there (the one you added earlier). By saving this server-side it allows it to be run each time the client loads the page because the browser still reads it as code to be ran. It should not - it should view it as text.
You'll notice that the first word in the background "test" is written, and the script has appeared. This is a blocking script, meaning no further code will be ran until you click the OK button in the dialog allowing the code to continue rendering the rest of the content on the page; hence why the second "test" word waits until you click okay before rendering the rest of the page.
Please let me know if I've missed anything out. Hope this helps
I'm in the beginning phases of developing a website. I want to be able to limit the amount of printing of web pages of circulars. These will be in an image format and usually consist of between 2 and 16 web pages. The circulars change each week.
Is there a way to limit the user to only 1 or X number of prints for each page and for each week? Is this easier done with standard web development or can it be done even easier in a content management system such as WordPress?
Not unless you have full control over the client-side.
You can TRY to prevent that SAME computer (via cookie) from
navigating to the same page twice.
If you are giving the user a unique ID to access the circular pages,
you can mark that ID as already having displayed the pages.
But there is simply no way to make sure that the user can't call the print calls in the browser.
One trick, which a js hacker could easily get around.. tie into the page printed event. The answers to that question talk about just how poorly the events are supported, and not cross-browser. If this browser has already had that event fire, nav away or change the #media rule for printing to return css making the whole page display:none (or some trickery).
As far as the actual print dialog ("Copies: x"), there's nothing you can do.
Is there a way to get a callback when a View appears/disappears on the screen?
I need this for analytics purposes - eg. I need to check how many times people saw a view versus how many times they clicked on it.
I can tell whether a view is on screen at a certain point in time but I'm wondering whether there is a callback for that.
Also note that I'm not interested when a View's state becomes VISIBLE and not even when a view gets rendered (because eg. in a ViewPager the Views of the second page are rendered before they actually appear on screen).
We did several workarounds for certain scenarios but I'd like to have something which is more generic. We need it in ListViews, GridViews, ScrollViews and ViewPagers and each one of them presents different challenges.
Does ViewTreeObserver.OnGlobalLayoutListener help? I have never used it myself though.
See: http://developer.android.com/reference/android/view/ViewTreeObserver.OnGlobalLayoutListener.html
Recently the DataSheet view of my list refuses to dispaly. I tried numerouse times and with no luck. Other lists works just fine, except for this one.
there is a Java error message on the left bottom corner of the screen that disapears in 2 seconds, then it renders the list in Standard view any time you try it.
I even created a new Datasheet View - the result a Standard View.
Any suggestions?
Thanks,
Here is a MS site regarding the data sheet view and why it may not be available - http://support.microsoft.com/kb/909506
The error occured after we installed an add-on to restrict users permissions. It looks like this solution afftects the functionality of the site (we tested it for a few days then disable it). Will wait for an improved solution.

I am using 5 UIWebViews in a UIScrollView to show the result of my game. Intention is to allow the user to scroll through the results screen. I had a problem where the UIWebViews won't load when scrolled to the next page. This means the first page will load successfully however when you scroll to Page 2, you will see a white blank page. Page is loaded as I can see the alert which was given in all the 5 pages, but it won't show.
I tried a workaround as mentioned here
inserting various views into UIScrollView

This fixed my problem, however when I submitted the app to iTunes, it got rejected with the following comment.
"3.3.1 Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs."
The non-public API that is included in your application is _documentView
I would like to fix this issue and resubmit. Can someone help please ?
Thanks

Just use one WebView for all results (which will scroll if it doesn't fit into the screen).
