  • Our Look at the Internet Explorer 9 Platform Preview

    - by Asian Angel
    Have you been hearing all about Microsoft’s work on Internet Explorer 9 and are curious about it? If you are wanting a taste of the upcoming release then join us as we take a look at the Internet Explorer 9 Platform Preview. Note: Windows Vista and Server 2008 users may need to install a Platform Update (see link at bottom for more information). Getting Started If you are curious about the systems that the platform preview will operate on here is an excerpt from the FAQ page (link provided below). There are two important points of interest here: The platform preview does not replace your regular Internet Explorer installation The platform preview (and the final version of Internet Explorer 9) will not work on Windows XP There really is not a lot to the install process…basically all that you will have to deal with is the “EULA Window” and the “Install Finished Window”. Note: The platform preview will install to a “Program Files Folder” named “Internet Explorer Platform Preview”. Internet Explorer 9 Platform Preview in Action When you start the platform preview up for the first time you will be presented with the Internet Explorer 9 Test Drive homepage. Do not be surprised that there is not a lot to the UI at this time…but you can get a good idea of how Internet Explorer will act. Note: You will not be able to alter the “Homepage” for the platform preview. Of the four menus available there are two that will be of interest to most people…the “Page & Debug Menus”. If you go to navigate to a new webpage you will need to go through the “Page Menu” unless you have installed the Address Bar Mini-Tool (shown below). Want to see what a webpage will look like in an older version of Internet Explorer? Then choose your version in the “Debug Menu”. We did find it humorous that IE6 was excluded from the choices offered. Here is what the URL entry window looks like if you are using the “Page Menu” to navigate between websites. Here is the main page of the site here displayed in “IE9 Mode”…looking good. Here is the main page viewed in “Forced IE5 Document Mode”. There were some minor differences (colors, sidebar, etc.) in how the main page displayed in comparison to “IE9 Mode”. Being able to switch between modes makes for an interesting experience… As you can see there is not much to the “Context Menu” at the moment. Notice the slightly altered icon for the platform preview… “Add” an Address Bar of Sorts If you would like to use a “make-shift” Address Bar with the platform preview you can set up the portable file (IE9browser.exe) for the Internet Explorer 9 Test Platform Addressbar Mini-Tool. Just place it in an appropriate folder, create a shortcut for it, and it will be ready to go. Here is a close look at the left side of the Address Bar Mini-Tool. You can try to access “IE Favorites” but may have sporadic results like those we experienced during our tests. Note: The Address Bar Mini-Tool will not line up perfectly with the platform preview but still makes a nice addition. And a close look at the right side of the Address Bar Mini-Tool. In order to completely shut down the Address Bar Mini-Tool you will need to click on “Close”. Each time that you enter an address into the Address Bar Mini-Tool it will open a new window/instance of the platform preview. Note: During our tests we noticed that clicking on “Home” in the “Page Menu” opened the previously viewed website but once we closed and restarted the platform preview the test drive website was the starting/home page again. Even if the platform preview is not running the Address Bar Mini-Tool can still run as shown here. Note: You will not be able to move the Address Bar Mini-Tool from its’ locked-in position at the top of the screen. Now for some fun. With just the Address Bar Mini-Tool open you can enter an address and cause the platform preview to open. Here is our example from above now open in the platform preview…good to go. Conclusion During our tests we did experience the occasional crash but overall we were pleased with the platform preview’s performance. The platform preview handled rather well and definitely seemed much quicker than Internet Explorer 8 on our test system (a definite bonus!). If you are an early adopter then this could certainly get you in the mood for the upcoming beta releases!

  • Why Hebrew letters in the address bar break the ARR gateway (Only With Explorer 8,9,10)?

    - by Noamway
    The ARR is working great in all browsers except Internet Explorer 8,9,10. When I paste Hebrew URL directly to the address bar it's working good, but when I surf (click on a simple href URL) from one Hebrew URL page to another Hebrew URL the ARR return me that error: "502 - Web server received an invalid response while acting as a gateway or proxy server." There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server. I checked it number of times including with HTTP analyzer and I saw that the "referer" is making all the problems and cause to that error. For example when I enter to that page: mydomain.com/somehebrewchars (mydomain.com/???? you will need Hebrew install) And click in the page on a link to: mydomain.com/somehebrewchars2 (mydomain.com/???????? you will need Hebrew install) I will get the error above and when you look at the referrer you will see something like that: mydomain.com/עמוד-× ×—×™×ª×” We use other proxies application to others projects and we don't have the same issue like that. For this example we used WIN 2008 and 2012 with ARR 2.5 and also 3 beta. Any help is welcome :-) Thanks, Noam

  • Can Safari 5.1 for Mac OS display favicons for bookmarks in the Bookmarks Bar?

    - by Greg R.
    When bookmarking a web site, most contemporary browser will display the site's favicon next to the bookmark, both in the bookmark view and the bookmark toolbar. This is a useful feature. In the bookmark toolbar you can edit the name of the bookmark to be blank, effectively leaving the favicon there as an easily identifiable "button" from which to launch the bookmark. This allows you to make more effective user of the space in the bookmark toolbar. I use this approach effectively in Firefox, Chrome, and IE. For example, here is a portion of my Bookmarks Toolbar from Firefox: However, in Safari, no favicon is ever displayed for bookmarks. In the full bookmark view only a generic globe icon is displayed. In the Bookmark Bar in Safari, no icon at all is displayed. Which means the habit of removing the bookmark name & leaving the favicon is useless. Here's what the same configuration (synced between browsers via Xmarks) looks like in Safari. That blank space is where the favicons should be. The boomark is there -- if you hover over it, the blank space changes color to indicate the presence of a bookmark and a tool tip will with the URL will pop up after about two seconds. However, it's really quite unusable. So. The question: is there an extension, plug-in, or modification of some sort that will enable the display of favicons for bookmarks in Safari (OS X Lion 10.7.3 , Safari version 5.1.3)?

  • iTunes Title Bar is Equal to the Location of the Library file?

    - by Urda
    I have never been able to get a clear answer on why the latest edition of iTunes does this. I have my entire iTunes library located in C:\itunes\ and the library data files inside C:\itunes\!library_info for backup purposes. However when version 9 of iTunes came out it went from having iTunes as the title, to !library_info. Anyway to get around this without moving my data files away? Annoying "feature" if that is what it is. Again Apple support and forums were of no help to me. Anyone have insight on this? System Info: Windows Vista x86 Ultimate, latest updates. iTunes Version 9.0.3.15 Screenshot: http://farm5.static.flickr.com/4072/4414557544_d0b25eb64c_o.jpg Flickr Page: http://www.flickr.com/photos/urda/4414557544/ UPDATE: I put a bounty on this, and would be open to hacking the registry or doing a custom config. Please help me fix my title bar!!! Update2: I would not like to move my library files out of itunes\!library_info to avoid them inter-mingling with my music library.

  • Is there a simple context-menu add-in that could make-up for the Windows-7 status bar deficiency?

    - by DanO
    Edit: I initially asked about free disk space and selected item size. It has since been pointed out that the selected item size summary is still availiable natively in the details pane. I had read elsewhere (wikipedia) that this was removed along with disk free space, which is not the case. Only free disk space has been completely removed. Selection size is still availiable. Is there a context menu add-in out there that could show the free disk space of the relevant drive, when you right click? This would go a long way to compensating for one of the only steps backward I’ve discovered in Windows 7 so far. I doubt anyone had created one specifially for this need before windows 7 because this information was previously easily accessible in the status bar. I thought about creating one, but it has been a while since I have messed with the Shell API, and I know there are coders out there who could do it faster and better. If you’ve heard of one, or know of something else to make-up for this Microsoft misstep, I’d appreciate hearing about it. If MS were listing to the community they would already have a powertoy or add-in of some kind to un-break this. (they could release it unsupported even), as there seem to be many power users that are extremely annoyed by this feature removal decision. If anyone has seen something, please post it here. As it has been only 4 days since official Windows 7 release, I'll wait at least a week to chose an answer. Here's a picture of protoype screenshot: SU question 19232 is related.

  • How do you create a dynamic excel chart?

    - by Haris
    I am looking at creating an Excel chart that offers some interactivity. Basically, at the moment I have a chart that is detailing progress (in %) using bars. But that progress is usually made up of several other aspects. So you could have an overall progress of say 50% which would then be broken down into Graphics 75%, Sound 25%, Gameplay 50%. Now what I'd like to do is find a way to stack those bars, so that I have the bar showing the overall progress and only when I click on that bar the other, more detailed progress bars appear. Is there a way to do this in Excel? Thanks in advance!

  • Should we persist with an employee still writing bad code after many years?

    - by user94986
    I've been assigned the task of managing developers for a well-established company. They have a single developer who specialises in all their C++ coding (since forever), but the quality of the work is abysmal. Code reviews and testing have revealed many problems, one of the worst being memory leaks. The developer has never tested his code for leaks, and I discovered that the applications could leak many MBs with only a minute of use. User's were reporting huge slowdowns, and his take was, "it's nothing to do with me - if they quit and restart, it's all good again." I've given him tools to detect and trace the leaks, and sat down with him for many hours to demonstrate how the tools are used, where the problems occur, and what to do to fix them. We're 6 months down the track, and I assigned him to write a new module. I reviewed it before it was integrated into our larger code base, and was dismayed to discover the same bad coding as before. The part that I find incomprehensible is that some of the coding is worse than amateurish. For example, he wanted a class (Foo) that could populate an object of another class (Bar). He decided that Foo would hold a reference to Bar, e.g.: class Foo { public: Foo(Bar& bar) : m_bar(bar) {} private: Bar& m_bar; }; But (for other reasons) he also needed a default constructor for Foo and, rather than question his initial design, he wrote this gem: Foo::Foo() : m_bar(*(new Bar)) {} So every time the default constructor is called, a Bar is leaked. To make matters worse, Foo allocates memory from the heap for 2 other objects, but he didn't write a destructor or copy constructor. So every allocation of Foo actually leaks 3 different objects, and you can imagine what happened when a Foo was copied. And - it only gets better - he repeated the same pattern on three other classes, so it isn't a one-off slip. The whole concept is wrong on so many levels. I would feel more understanding if this came from a total novice. But this guy has been doing this for many years and has had very focussed training and advice over the past few months. I realise he has been working without mentoring or peer reviews most of that time, but I'm beginning to feel he can't change. So my question is, would you persist with someone who is writing such obviously bad code?

  • I want to input JSONObject from jquery.post() to a a simple JS chart(bar chart)?

    - by ann-stack
    HI I am very new to both json and js charts. In the example of bar chart, they are giving a hard coded array like this, var myData = new Array(['U.S.A.', 69.5], ['Canada', 2.8], ['Japan & SE.Asia', 5.6] ); var myChart = new JSChart('graph', 'bar'); myChart.setDataArray(myData); Instead of that I want to use the response of $.post() method which is in json. Here is the piece of code. var myData=[]; $.post("JSONServlet", function(data) { $.each(data.Userdetails, function(i, data) { myData[i] = []; myData[i]['text'] = data['firstname']; myData[i]['id'] = data['ssn']; alert("first name " +myData[i]['text']+ " salary " +myData[i]['id']); // I am getting correct data here, but how to assign this myData to barchart }); }, "json"); is this the logic to use or how else can i get username and salary from the response and pass it to the barchart. Please help. I am stuck with this. thanks in advance.

  • IE Information Bar, download file...how do I code for this?

    - by flatline
    I have a web page (asp.net) that compiles a package then redirects the user to the download file via javascript (window.location = ....). This is accompanied by a hard link on the page in case the redirect doesn't work - emulating the download process on many popular sites. When the IE information bar appears at the top due to restricted security settings, and a user clicks on it to download the file, it redirects the user to the page, not the download file, which refreshes the page and removes the hard link. What is the information bar doing here? Shouldn't it send the user to the location of the redirect? Am I setting something wrong in the headers of the download response, or doing something else wrong to send the file in the first place? C# Code: m_context.Response.Buffer = false; m_context.Response.ContentType = "application/zip"; m_context.Response.AddHeader("Content-Length", fs.Length.ToString()); m_context.Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}_{1}.zip", downloadPrefix, DateTime.Now.ToString("yyyy-MM-dd_HH-mm"))); //send the file

  • How to make Firefox extension auto install in nav bar?

    - by S M
    I'm working on a Firefox extension. I'd like to make it auto-install in the far right position on the nav bar when a user installs it. As it stands, a user has to go to View Toolbars Customize... and drag the extension to the nav bar once it's installed. I'd like to eliminate this step. The extension is here: http://madan.org/tickertool The XUL for my extension looks basically like this and it overlays browser.xul: <overlay id="my-ext-overlay" ... > <toolbarpalette id="BrowserToolbarPalette"> <toolbaritem id="my-ext-container" ... > <toolbarbutton id="my-ext-customize-image" ... /> <textbox id="my-ext-textbox" ... /> <hbox id="my-ext-buttons"> <image id="my-ext-button1" ... /> <image id="my-ext-button2" ... /> <image id="my-ext-button3" ... /> </hbox> </toolbaritem> </toolbarpalette> </overlay> I've seen code here ( https://developer.mozilla.org/en/Code_snippets/Toolbar ) that supposedly does what I'm looking for, but this code is if your extension is just a single button and I can't get it to work for me. The answer to my question is likely some modification of this code, but I haven't figured it out.

  • How to automatically extend the tab control as items are added to it without creating a scroll bar?

    - by MICHELINE
    I am using a WPF user control (tab control) to add tab items dynamically in the simplified code below: .... foreach (string id in ids) { TabControl.Items.Add(CreateTabItem(id)); } private TabItem CreateTabItem(string name) { StackPanel txtBlock = new TextBlock(); txtblock.Text = name; txtBlock.HorizontalAlignment = Horizontalalignment.Center; panel.Children.Add(txtBlock); TabItem item = new TabItem(); item.Header = panel; <SomeControl> control = new <SomeControl>(); item.Content = control; return item; } In the xaml file I specified the following to stack all my tab items to the left column: MinWidth="100" MinHeight="300" TabStripPlacement="Left" How do I make my tab control automatically extending (ie. stretching) its height to show all the tab items as I add them in? For now, I have to manually extend the height of the display window to see all the tab items. Your insights/tips are greatly appreciated. PS: if you know how to make the vertical scroll bar appears (without adding scroll bar to my control) as soon as the tab items exceed the window height, I can settle for that if there are no answers for my original intent.

  • Update iPhone UIProgressView during NSURLConnection download.

    - by Scott Pendleton
    I am using this code: NSURLConnection *oConnection=[[NSURLConnection alloc] initWithRequest:oRequest delegate:self]; to download a file, and I want to update a progress bar on a subview that I load. For that, I use this code: - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [oReceivedData appendData:data]; float n = oReceivedData.length; float d = self.iTotalSize; NSNumber *oNum = [NSNumber numberWithFloat:n/d]; self.oDPVC.oProgress.progress = [oNum floatValue]; } The subview is oDPVC, and the progress bar on it is oProgress. Setting the progress property does not update the control. From what I have read on the Web, lots of people want to do this and yet there is not a complete, reliable sample. Also, there is much contradictory advice. Some people think that you don't need a separate thread. Some say you need a background thread for the progress update. Some say no, do other things in the background and update the progress on the main thread. I've tried all the advice, and none of it works for me. One more thing, maybe this is a clue. I use this code to load the subview during applicationDidFinishLaunching: self.oDPVC = [[DownloadProgressViewController alloc] initWithNibName:@"DownloadProgressViewController" bundle:nil]; [window addSubview:self.oDPVC.view]; In the XIB file (which I have examined in both Interface Builder and in a text editor) the progress bar is 280 pixels wide. But when the view opens, it has somehow been adjusted to maybe half that width. Also, the background image of the view is default.png. Instead of appearing right on top of the default image, it is shoved up about 10 pixels, leaving a white bar across the bottom of the screen. Maybe that's a separate issue, maybe not.

  • How to estimate size of data to transfer when using DbCommand.ExecuteXXX?

    - by Yadyn
    I want to show the user detailed progress information when performing potentially lengthy database operations. Specifically, when inserting/updating data that may be on the order of hundreds of KB or MB. Currently, I'm using in-memory DataTables and DataRows which are then synced with the database via TableAdapter.Update calls. This works fine and dandy, but the single call leaves little opportunity to glean any kind of progress info to show to the user. I have no idea how much data is passing through the network to the remote DB or its progress. Basically, all I know is when Update returns and it is assumed complete (barring any errors or exceptions). But this means all I can show is 0% and then a pause and then 100%. I can count the number of rows, even going so far to cound how many are actually Modified or Added, and I could even maybe calculate per DataRow its estimated size based on the datatype of each column, using sizeof for value types like int and checking length for things like strings or byte arrays. With that, I could probably determine, before updating, an estimated total transfer size, but I'm still stuck without any progress info once Update is called on the TableAdapter. Am I stuck just using an indeterminate progress bar or mouse waiting cursor? Would I need to radically change our data access layer to be able to hook into this kind of information? Even if I can't get it down to the precise KB transferred (like a web browser file download progress bar), could I at least know when each DataRow/DataTable finishes or something? How do you best show this kind of progress info using ADO.NET?

  • Calculate total batch upload transfer percent with limited information

    - by GONeale
    Hi there, I have a system which uploads to a server file by file and displays a progress bar on file upload progress, then underneath a second progress bar which I want to indicate percentage of batch complete across all files queued to upload. Information and algorithms I can work out are: Bytes Sent / Total Bytes To Send = First progress bar (eg. 512KB of 1024KB (50%)) That works fine. However supposing I have two other files left to upload, but both file sizes are unknown (as this is only known once the file is about to commence upload, at which point it is compressed and file size is determined) how would I go about making my third progress bar? I didn't think this would be possible as I would need "Total Bytes Sent" / "Total Bytes To Send", to replicate the logic of my first progress bar on a larger scale, however I did get a version working: "Current file number we are on" / "total number of files to send" returning the percentage through the batch, however obviously will not incrementally update and it's pretty crude. So on further thinking I thought if I could incorporate the current file % with this algorithm I could perhaps get the correct progress percentage of my batch's current point. I tried this algorithm, but alas to no such avail (sorry to any math heads, it's probably quite apparent why it won't work) ("Current file number we are on" / "total number of files to send") * ("Bytes Sent" / "Total Bytes To Send") For example I thought I was on the right track when testing with this example: 2/3 (2nd of 3rd file) = 66% (this is right so far) but then when I added * 0.20 (for indicating only 20% of 2nd file has uploaded) we went back to 13%. What I need is only a little over 33%! I did try the inverse at 0.80 and a (2/3 * (2/3 * 0.2)) Can this be done without knowing entire bytes in batch to upload? Please help! Thank you!

  • Python 4 step setup with progressBars

    - by Samuel Taylor
    I'm having a problem with the code below.
