  • Finally, upgrade from Nokia X3 to Samsung Galaxy S III

    This time, something slightly different but nonetheless not less interesting, hopefully. Living on a remote island like Mauritius, ill-praised 'Cyber Island' in the Indian Ocean, has its advantages in life style and relaxed environment to life in but in terms of technological aspects it can be quite a nightmare. Well, I guess this might be different story to report about... one day. Cyber Island Mauritius Despite it's shiny advertisement as Cyber Island and business in ICT hub to Africa, Mauritius is not on the latest track of available models in computer hardware or, in the context of this article, cellulars or smart-phone, or communication technology in general. Okay, I have to admit that this statement is only partly true. Money can buy, even here in Mauritius. Luckily, there are ways and ways to deal with this outcry of modern, read: technological, civilisation issues. Online shopping you might think? Yes, for sure, until you discover in your checkout procedure that a small island in the Indian Ocean isn't a preferred destination for delivery and the precious time you spent on putting your items into your cart and feeding your personal level of anticipation gets ruined on the last stint. Ordering from abroad saves you money Anyway, I got in touch with my personal courier and luckily there were some extra-kilos left in the luggage. First obstacle sorted, we have a Transporter! Okay, on the next occasion off to Amazon online and using their Prime service for fast delivery. Actually, the order was placed on Saturday evening and everything got delivered on Tuesday morning - nice job in less than 72 hours. Okay, among the items of that shopping rush I ordered a shiny Samsung Galaxy S III 16GB in oceanic blue - did I mention, that you hardly get a blue model in Mauritius? - for my BWE. Interesting side-notes: First, Amazon Germany dropped the prices for roughly 30% on the S3, and we got the 16GB model for less than 500 Euro (or approx. Rs. 19.500,-) compared to the usual Rs. 27.000,- on the local market. It even varies whether the local price is inclusive or exclusive VAT (15%). Second, since a while she was bothering me to get an iPhone and an iPad for her, fair enough I thought, decent hardware, posh design and reliable services. Until we watched the 'magical' introduction of Samsung's new models at the IFA exhibition, she read the bashing comments on Google+ on the iPhone 5 and I gave her a brief summary on the law suit between Apple and Samsung in the USA. So, yes, Samsung USA is right, the next big thing is already here - literally. My BWE loves the look and touch of the Galaxy S3. And for me it was more cost-effective in terms of purchases done at the App Store, ups, Play Store. Transfer of contacts, text messages and media files Okay, now that the hardware is in place, how to transfer all those contacts, text messages, media files, etc. between those two devices? In the past, I used to use the Nokia Communication Suite between various models but now for Android? Well, as usual Google and Bing are reliable friends and among the first hits I came across an article about How to Transfer Contacts from Nokia to Android. Couldn't be easier, right? Well, sort of... my main Windows systems are already running on Windows 8, and this actually caused problems with the mobile/smart-phone device drivers. The article provides the download for an older version 1.10 which upgrades to 2.11 (as time of writing this entry) but both couldn't get the Galaxy S3 and the Nokia connected. Shame on me... the product page clearly doesn't mention Windows 8 (for now) and Windows 8 isn't available for the general audience at all... After I took a spare machine running on Windows Vista everything went smooth. Software installed, upgrade done, device drivers for Android automatically downloaded and installed, and the same painless routine for the Nokia part. I think, I rebooted the system twice during the whole setup procedure but hey, it was more or less a distraction while coding some stuff in ASP.NET MVC and Telerik Kendo UI. The transfer of contacts and text messages was done via Wondershare MobileGo for Android, and all media files by moving the additional microSD card from one device to the other. But even without an external SD card, it would have been very easy to copy the files via Windows Explorer directly. Little catch and excellent service Fine, we are almost done and the only step left is to shift the SIM card... Ouch, gotcha! The X3 uses a standard size SIM card while the S III only accepts microSIM form factor. What an irony, bigger smartphone needs smaller SIM card. Luckily, the next showroom of Emtel is just 5 mins away up the road, and the service staff over there know their job. Finally, after roughly 10 mins of paper work, activation and small chit-chat, the S3 came to life on the mobile network. Owning a smart-phone now and knowing that my BWE would like to interact more on social networks away from home, especially to upload pictures and provide local 'check-ins', I activated a data package for her in advance, too. Even that it is Saturday, everything was already done and ready to be used. Nice bonus: The Emtel clerk directly offered me to set up the configuration for the Emtel data services, yes sure, go ahead, this saves me to search for that in the settings. Okay, spoiler-alert here, setting a static APN to access the Emtel network and the internet wouldn't be a challenge. But hey, she already had the phone in her hands and I could keep my eyes on the children. Well done, Emtel! Resume Thanks to the useful software package by Wondershare is was a hands-free experience to transfer all the data from a Nokia mobile on Symbian S60 to a Samsung Galaxy S III on Android Ice Cream Sandwich (ICS). In the future, this wont be a serious issue at all anymore thanks to synchronisation services and cloud storage. And for now, I'm only waiting for the official upgrades for Jelly Bean.

  • How can I export PDF from InDesign so that transparency renders properly on all platforms?

    - by strangeronyourtrain
    Gradients, including drop shadows, all show up as solid blocks when I view my document on an Android phone. I tried different PDF compression and compatibility settings in an attempt to flatten and rasterize all the graphics, but it's clearly not working, as the Android viewer still identifies the outlines of transparent shapes instead of the blended pixels. Is there any way to truly flatten these PDF graphics, so that it doesn't matter whether a PDF viewer supports transparency, while keeping the text as text?

  • Where can I report an issue with IIS?

    - by Nathan Taylor
    While working with an ASP.NET application on Chrome for Android I discovered that Request.Browser.Cookies returns False for that browser (despite the browser supporting cookies). Based on what I've read, this indicates a problem with the database which ASP.NET (and, I assume, IIS) uses to look up information about different UserAgents. The fact that it returns False means that the database is either missing Chrome for Android, or has invalid data for it. What is the a proper place to report IIS issues like this?

    So it seems like there are many solutions (Boxee, GoogleTV, AppleTV, XMBC, etc) out there for HTPC setups but I can't seem to find a good solution for playing MKV files and I would say the bulk of my video library is encoded in MKVs. Whats a good solution for an HTPC if I want the following: NAS / Samba support to use files from server or Windows share Preferably Linux based solution Cleanish UX Nice to have but not a requirement: - Android Remote App so I can control with my Android device

  • Building a video wall with devices

    - by machunter
    I am entertaining building a video wall made out of many android devices. But I have to say I have no clue about how to go about it? The fact that these are android devices is not very important I am curious about the general approach to doing video walls with many separated devices. At best the desktop of one machine should be displayed on all the devices. If not I would be also interested in just showing just a video on that wall.

  • C# / WPF / .NET - Drag and drop to Desktop / Explorer

    - by Dänu
    Hey Guys Following my scenario. I got an Application which loads a Filestructure (Folders, Files) from a Database into a WPF ListView. Now I'd like to grab a file from this ListView, drag it over my Desktop (or some open explorer window) and drop it there. Basic Drag and Drop, nothing fancy. This sounds like a "standard" function for a windows application - but google won't help. So how can I achieve this? Interops? Thanks Edit: Thanks for the solution, I still had to do some googling. Here's my complete solution.

  • ConfirmButtonExtender using ModalPopupExtender fails in UpdatePanel after partial postback?

    - by Martin Emanuelsson
    Hello, We're trying to add a more fancy looking confirm messages than the regular JavaScript-confirm message to our delete-buttons in a list of comments on our site. To accomplish this we're trying to use the ConfirmButtonExtender together with a ModalPopupExtender. The comments are displayed using a ListView inside a UpdatePanel so that the paging of the ListView doesn't reload the entire page. Using the ConfirmButtonExtender works fine the first time the list is loaded but if we for instance go to the second page of comments using the pager, the ConfirmButtonExtender doesn't work anymore. The extender shows up when clicking Delete but when I click OK the page makes a full reload without triggering the delete event. Has anyone experienced the same problem and found a solution to it? Or can you recommend another way to accomplish the same thing? Best regards Martin Emanuelsson Göteborg, Sweden

  • Disable selecting in WPF DataGrid

    - by svick
    How can I disable selecting in a WPFTooklit's DataGrid? I tried modifying the solution that works for ListView (from http://stackoverflow.com/questions/1051215/wpf-listview-turn-off-selection#comment-863179), but that doesn't work: <tk:DataGrid> <tk:DataGrid.ItemContainerStyle> <Style TargetType="{x:Type tk:DataGridRow}"> <Setter Property="Focusable" Value="false"/> </Style> </tk:DataGrid.ItemContainerStyle> <tk:DataGrid.CellStyle> <Style TargetType="{x:Type tk:DataGridCell}"> <Setter Property="Focusable" Value="false"/> </Style> </tk:DataGrid.CellStyle> </tk:DataGrid>

  • DataGridView Selected Row Move UP and DOWN

    - by Silly Rabbit
    How can I allow selected rows in a DataGridView (DGV) to be moved up or down. I have done this before with a ListView. Unfortunetly, for me, replacing the DGV is not an option (curses). By the way, the DGV datasource is a Generic Collection. The DGV has two buttons on the side, yes, UP & Down. Can anyone help point me in the right direction. I do have the code that I used for the ListView if it'll help (it did not help me).

  • How to "bubble" a Controls features when place in a custom UserControl

    - by Ted
    I'll try to explain what Im after. I dont know the technical term for it, so here goes: Example 1: If I place a LisView on a Form and add som columns I am able, in Design-Time, to click-and-drag the columns to resize them. Example 2: Now, I place a ListView in a UserControl and name it "MyCustomListView" (and perhaps add some method to enhance it somehow). If I know place the "MyCustomListView" on a Form I am unable to click-and-drag the column headers to resize them in Design-Time. Is there any way to easily make that happen? Some form of "pass the click-and-drag event to the underlying control and let that control do its magic". Im not really looking to recode, just pass on the mouseclick (or whatever it is) and let the, in this case, ListView react as it did in the first example above. Regards

  • TVirtualStringTree - resetting non-visual nodes and memory consumption

    - by Remy Lebeau - TeamB
    I have an app that loads records from a binary log file and displays them in a virtual TListView. There are potentially millions of records in a file, and the display can be filtered by the user, so I do not load all of the records in memory at one time, and the ListView item indexes are not a 1-to-1 relation with the file record offsets (List item 1 may be file record 100, for instance). I use the ListView's OnDataHint event to load records for just the items the ListView is actually interested in. As the user scrolls around, the range specified by OnDataHint changes, allowing me to free records that are not in the new range, and allocate new records as needed. This works fine, speed is tolerable, and the memory footprint is very low. I am currently evaluating TVirtualStringTree as a replacement for the TListView, mainly because I want to add the ability to expand/collapse records that span multiple lines (I can fudge it with the TListView by incrementing/decrementing the item count dynamically, but this is not as straight forward as using a real tree). For the most part, I have been able to port the TListView logic and have everything work as I need. I notice that TVirtualStringTree's virtual paradigm is vastly different, though. It does not have the same kind of OnDataHint functionality that TListView does (I can use the OnScroll event to fake it, which allows my memory buffer logic to continue working), and I can use the OnInitializeNode event to associate nodes with records that are allocated. However, once a tree node is initialized, it sees that it remains initialized for the lifetime of the tree. That is not good for me. As the user scrolls around and I remove records from memory, I need to reset those non-visual nodes without removing them from the tree completely, or losing their expand/collapse states. When the user scrolls them back into view, I can re-allocate the records and re-initialize the nodes. Basically, I want to make TVirtualStringTree act as much like TListView as possible, as far as its virtualization is concerned. I have seen that TVirtualStringTree has a ResetNode() method, but I encounter various errors whenever I try to use it. I must be using it wrong. I also thought of just storing a data pointer inside each node to my record buffers, and I allocate and free memory, update those pointers accordingly. The end effect does not work so well, either. Worse, my largest test log file has ~5 million records in it. If I initialize the TVirtualStringTree with that many nodes at one time (when the log display is unfiltered), the tree's internal overhead for its nodes takes up a whopping 260MB of memory (without any records being allocated yet). Whereas with the TListView, loading the same log file and all the memory logic behind it, I can get away with using just a few MBs. Any ideas?

  • How can I drag and drop a xaml activity to a WF4 rehosted designer?

    - by Louis Rhys
    I understand that the WorkflowDesigner can receive a dragged item in several ways, for example: By dragging an item from the toolbox and dropping it on the designer: an empty activity of that type will be inserted on the designer at the drop location. One can also drag an activity from the designer and drop it on another location in the designer, the dragged activity will be inserted at the drop location as well. Is it possible that similar to these two drag and drop mechanism, I can drag a xaml activity to the designer? What I have in mind is this, Let's say you have a ListView containing several xaml files. I want to be able to drag one of the ListView items (ie one of the xaml files), and when I drag it over the designer it will act as if I drag something from the toolbox (except the activity will be supplied from the xaml). I know I can create a runtime Activity from the file by using ActivityXamlServices.Load(filename), and I want this activity to be inserted at the drop location. But how to tell the application to understand this when I drag and drop?

  • Why is the JVM stack-based and the DalvikVM register based?

    - by aioobe
    I'm curious, why did Sun decide to make the JVM stack-based and Google decide to make the DalvikVM register based? I suppose the JVM can't really assume that a certain number of registers are available on the target platform, since it is supposed to be platform independent. Therefor it just postpones the register-allocation etc, to the JIT compiler. (Correct me if I'm wrong.) So the Android guys thought, "hey, that's inefficient, let's go for a register based vm right away..."? But wait, there are multiple different android devices, what number of registers did the Dalvik target? Are the Dalvik opcodes hardcoded for a certain number of registers? Do all current Android devices on the market have about the same number of registers? Or, is there a register re-allocation performed during dex-loading? How does all this fit together?

  • an enter key are handled twice in WPF/Winform mixed project

    - by user527403
    I have a winform dashboard which hosts some WPF dialogs. When I select a row in the winform ListView and hit Enter key, OnItemActivate is called which launches a WPF dialog. However, the WPF dialog appears and then disappears immediately because the default button “cancel” is hit. It seems that the Enter key is triggered twice, one for launching the WPF dialog, the other for hitting cancel button. We don’t want the WPF dialog to be canceled by the Enter key hitting. According to the stack trace, it looks like that WPF and Winform handle the enter key separately. The WPF does not know that the enter key has been handled by the Winform ListView. Is this by design in Winform and WPF interop? To make the enter key not close the WPF dialog, we have to change the focus from the cancel button to another control (e.g. a textblock). Is there a better way to fix/around this issue?

  • Hidden features of WPF and XAML?

    - by Sauron
    Here is a large number of hidden features discussed for variety of languages. Now I am curious about some hidden features of XAML and WPF? One I have found is the header click event of a ListView <ListView x:Name='lv' Height="150" GridViewColumnHeader.Click="GridViewColumnHeaderClickedHandler"> The GridViewColumnHeader.Click property is not listed. Some of relevant features so far: Multibinding combined with StringFormat TargetNullValue to bindings TextTrimming property Markup extensions Adding Aero effect to Window Advanced "caption" properties XAML Converters See also: Hidden features of C# Hidden features of Python Hidden features of ASP.NET Hidden features of Perl Hidden features of Java Hidden features of VB.NET Hidden features of PHP Hidden features of Ruby Hidden features of C And So On........

  • ado.net managing connections

    - by madlan
    Hi, I'm populating a listview with a list of databases on a selected SQL instance, then retrieving a value from each database (It's internal product version, column doesn't always exist) I'm calling the below function to populate the second column of the listview: item.SubItems.Add(DBVersionCheck(serverName, database.Name)) Function DBVersionCheck(ByVal SelectedInstance As String, ByVal SelectedDatabase As String) Dim m_Connection As New SqlConnection("Server=" + SelectedInstance + ";User Id=sa;Password=password;Database=" + SelectedDatabase) Dim db_command As New SqlCommand("select Setting from SystemSettings where [Setting] = 'version'", m_Connection) Try m_Connection.Open() Return db_command.ExecuteScalar().trim m_Connection.Dispose() Catch ex As Exception 'MessageBox.Show(ex.Message) Return "NA" Finally m_Connection.Dispose() End Try End Function This works fine except it's creating a connection to each database and leaving it open. My understanding is the close()\dispose() releases only the connection from the pool in ado rather than the actual connection to sql. How would I close the actual connections after I've retrieved the value? Leaving these open will create hundreds of connections to databases that will probably not be used for that session.

  • Create list-of-controls in Windows.Forms

    - by leiflundgren
    I have decided that I would like to have a list with "complex context", i.e. of custom-controls. (The goal is something looking like a buddy list, with photos, status-icons, text, "start-chat-button".) But I like it to behave as a list: scrollbars, possibility to select multiple items etc. When I have been looking at ListView and ListBox I only see that I can add text and an icon, but not arbitrary controls. I'm I missing how this is done? Or should I use something else then ListView/ListBox?

  • ASP.NET and SQL server with huge data sets

    - by Jake Petroules
    I am developing a web application in ASP.NET and on one page I am using a ListView with paging. As a test I populated the table it draws from with 6 million rows. The table and a schema-bound view based off it have all the necessary indexes and executing the query in SQL Server Management Studio with SELECT TOP 5 returned in < 1 second as expected. But on the ASP.NET page, with the same query, it seems to be selecting all 6 million rows without any limit. Shouldn't the paging control limit the query to return only N rows rather than the entire data set? How can I use these ASP.NET controls to handle huge data sets with millions of records? Does SELECT [columns] FROM [tablename] quite literally mean that for the ListView, and it doesn't actually inject a TOP <n> and does all the pagination at the application level rather than the database level?

  • AVD Failed to Load ~ Failed to Parse Properties ~ Mac OSX

    - by C.D. OKeefe
    I'm going to say upfront, please forgive me. I'm a newbie to android development and fairly new to programming. Also on a Mac. You're going to have to talk...real...slow. I can't get an AVD to load. I've tried it from Eclipse and from the Android SDK Manager. Failed multiple times. Received the same error each time, "Failed to parse properties from Users/myname/.android/avd/nameIGaveEmulator/config.ini." I've the forum here and saw that others have had similar problems, but of the answers given, no one came back to say if they worked, and I don't see anyone with a similar problem on a Mac. If the path needs to be "changed" what exactly does that mean and how do I go about doing so?
