  • Sync data between a windows desktop app and windows mobile client app

    - by Chris W
    I need to knock up a very quick prototype/proof of concept application to demo to someone within the next couple of days so I've minimal time to research this as fully as I normally would. The set-up is a very simple database application running on a laptop - will only ever be a single user updating a couple of tables so I was thinking of knocking up a basic Win Forms app against SQL Compact. Visual Studio's auto generated data grid edit screens will be fine with a little customisation. The second aspect is to then add a windows mobile client application that can pull data from both tables stored on the laptop, edit some data and insert some extra rows before sending the changes back to the laptop copy of the database. I've not done any WinMo development so what's the best approach for me to look at. Is it easy enough to sync data between the two databases when the WinMo device is connected to the laptop with USB? Most of the samples I've looked at so far seem to be syncing SQL Compact with SQL Standard using IIS which seems a bit overkill. The volumes of data to be synced are so small that I can easily write some manual sync code if it's easy for me to query/update the Compact DB from the laptop application when the device is connected.

  • Transitioning from the web to the desktop

    - by Paul Anderssen
    Can anyone recommend a language, library, framework or book which focuses on GUI programming from the perspective of a web developer? I have experience in web development, for example HTML/AJAX/PHP/MySQL among similar technologies. However, I have never programmed my own back-end, or any kind of standalone program. Does anyone have experience making this transition, and what would I best study to help make the leap from the browser to creating programs with GUIs (primarily for Windows)?

  • Does html5 allow desktop execution?

    - by Shawn Mclean
    I want a functionality similiar to Adobe AIR or Silverlight Out of Browser but without the need for downloading plugins. I want the user to be on the site, then click install, javascript takes over and save itself to the local file system where it can then be clicked, then started up in the browser. Similiar to save-file. Html5 will handle the offline execution, etc.

  • Can Adobe AIR Desktop application take full screen snapshots (aka Print Screen button)

    - by tzador
    I would like to know if its possible to get full screen snapshots from an air application. What i am interested in, is functionality similar to PrintScreen button in windows, which takes snapshots of all screens, including third party application windows, not just window in which air app is running. If its not specific to air, and flash/flex API can provide such functionality, it also would be great. Thanx a lot in advance.

  • css menu for cross browser...mobile and desktop

    - by user1763319
    I made a cross browser drop down menu, which works well with IE6.

Link to JSFiddle Here is my CSS: <style> .bar ul,li{ z-index:999; margin:0; padding:0; } .bar { color: #FFFFFF; font-weight: bold; text-align: center; } .bar a { padding: 11px; } .bar a:visited { color: #FFFFFF; font-weight: bold; text-decoration:none } .bar a:link { color: #FFFFFF; font-weight: bold; text-decoration:none } .bar a:hover { color: #FFFFFF; font-weight: bold; text-decoration:underline } #nav0{ list-style:none; font-weight:bold; /* Clear floats */ float:left; width:100%; } #nav0 li{ float:left; margin-right:10px; position:relative; } #nav0 a{ display:block; padding:5px; color:#fff; background:#003399; text-decoration:none; } #nav0 a:hover{ color:#fff; background:#333; text-decoration:underline; } /*--- DROPDOWN ---*/ #nav0 ul{ background:#fff; background:rgba(255,255,255,0); list-style:none; position:absolute; left:-9999px; } #nav0 ul li{ padding-top:1px; float:none; } #nav0 ul a{ white-space:nowrap; } #nav0 li:hover ul{ left:0; } #nav0 li:hover a{ text-decoration:underline; } #nav0 li:hover ul a{ text-decoration:none; } #nav0 li:hover ul li a:hover{ background:#333; } #nav0 li ul li a{ text-align: left; } #nav0 li:hover ul li ul { display:block; background:#003399; float:left; position:relative; padding-left:20px; } #nav0 li ul li:hover ul { display:block; background:#003399; float:left; position:relative; padding-left:20px; } </style> Here is my HTML: <body bgcolor="#79A6A6"> <div id="page" align="center"> <table class="bar" border="0" width="960" cellspacing="0" cellpadding="0" id="table_bar" bgcolor="#003399"> <tr> <td> <ul id="nav0"> <li><a><strong>Home</strong> </a> <ul> <li><a href="#" title>Top Item 1</a><ul> <li><a href="#" title="-">Item 1</a></li> <li><a href="#" title="-">Item 2</a></li> </ul> </li> <li><a href="#" title>Top Item 2</a><ul> <li><a href="@" title>Item 3</a></li> <li><a href="@" title>Item 4</a></li> </ul> </li> </ul> </li> <li><a><strong>Home</strong> </a> <ul> <li><a href="#" title>Top Title</a><ul> <li><a href="#" title="-">title</a></li> <li><a href="#" title="-">title123456789</a></li> </ul> </li> <li><a href="#" title>Top Hello</a><ul> <li><a href="@" title>hello</a></li> <li><a href="@" title>hello123456789</a></li> </ul> </li> </ul> </li> </ul> </li> <ul> </ul> </td> <td width="50" style="text-align: left">&nbsp;</td> </tr> </table> </div> </body> In ie6 Home Top Item 1 Item 1 Item 2 Top Item 2 Item3 Item4 In ie9 Home Top Item 1 Top Item 2 Item 2 Item 3 Item 4

  • [ADVICE] .NET Desktop Application - Client Server C#, SQL

    - by Rillanon
    Hi guys, Recently I've being given a chance to develop a PMS (Practice Management System) software for a small physiotherapy clinic. I'm a computer science student and my course is predominately told on Linux. However, my client runs all their computers on vista or Windows 7. My ideas are to develop the client front end in Visual C# and access a central postgresql server. I'm a beginner in Windows Programming so I'm after advice on best practice on implement user rights and access levels in C# (WPF or Windows FORM). I've had a look into Credential class in Visual C# and access control list but please share your thoughts. I'm probably way over my head on this but this is my first commercial project so I'm keen to test the waters. Cheers Ian

  • AllowSetForegroundWindow & SetForegroundWindow: NPAPI plug-in wants to allow a desktop application with no success

    - by David Robert Jones
    Here it's what I have: a web browser plug-in written in C++ and a Windows application written in C#. They communicate through a named pipe. The plug-in instructs the C# application to open a file (suppose that the file is a .txt and it opens in Notepad). Once the C# application is given the command, it opens the file but Notepad doesn't show in the foreground, which isn't acceptable, I must open Notepad in the foreground. I modified the C# application so that it calls the SetForegroundWindow function. This time Notepad didn't open in the foreground, but the taskbar flashes. After reading the documentation for SetForegroundWindow and many articles I think that now I understand what the problem is: the C# application can't bring Notepad to the foreground because it wasn't the the foreground process, the browser was (?). After reading this: "A process that can set the foreground window can enable another process to set the foreground window by calling the AllowSetForegroundWindow function." I decided to modify the plug-in. This time the plug-in calls the AllowSetForegroundWindow function passing ASFW_ANY as a parameter (I know, ASFW_ANY could be risky, but I wanted to make sure that AllowSetForegroundWindow would do it). After I did the modification to the plug-in I tested it and it worked! (Opera 12.02). Then I tested it on Internet Explorer and it worked too. But the problem came when I tested it in Firefox and Chrome. The C# application didn't have the ability to bring Notepad to the foreground. I noticed that for those browsers the AllowSetForegroundWindow function was returning false. So I started investigating and I come to the conclusion that maybe it's because the plugin container that Firefox uses. An idea came to my mind: it worked in Opera 12.02, but they don't have a plugin container, although they did in Opera 12.00. So I downloaded Opera 12.00, I did the test and it failed, which makes me conclude that the plugin container is the culprit. The question is: how can I give to the C# application the ability to set foreground? I don't know how to continue, and I think that I tried all the legitimate ways. The AllowSetForegroundWindow & SetForegroundWindow seems to not apply here.

  • RHEL Desktop Recoders... Does they exist? [closed]

    - by Anarko_Bizounours
    Possible Duplicate: Screen capturing application for Linux I've been searching a lot for a desktop recoder on RHEL 6 lately (for tutorial video, about how to use RHEL desktop for non-linux users) But unfortunatly, didn't found anything... Just some Desktop recorder for ubuntu, none for Fedora or CentOS. (Maybe wasn't looking where I should have...) So there is my question, do you know a good desktop recorder on linux? There are my RHEL information : RHEL 6.1 x86_64 Kernel : 2.6.32-131.4.1.el6.x86_64 ps : If my RHEL configuration lack of information, ask me, and I'll provide them as quick as I can. Thanks in advance.

  • Android on Desktop tutorials/resources

    - by Ascension Systems
    I'm aware of the android-x86 project and as far as the end result (bootable live/install iso), I am looking to do the same thing. The difference is, I'm looking to do this with the ice cream sandwich branch from android master repo. Ice cream sandwich adds full support for x86 hardware and even sports a build target specifically for running the OS in virtualbox. So my question is, is anyone aware of any documentation for building and deploying to that target? Just in case it's not clear, I'm not just using the android-x86 project because they haven't yet put up a build for anything later than android 3.

  • How To Log Into The Desktop, Add a Start Menu, and Disable Hot Corners in Windows 8

    - by Chris Hoffman
    If you don’t have a touchscreen computer and spend all your time on the desktop, Windows 8’s new interface can seem intrusive. Microsoft won’t allow you to disable the new interface, but Classic Shell provides the options Microsoft didn’t. In addition to providing a Start button, Classic Shell can take you straight to the desktop when you log in and disable the hot corners that activate the charms and metro app switcher. There are other programs that do this, but Classic Shell is free and open-source. Many of the alternatives, such as Start8 and RetroUI, are commercial apps that cost money. We’ve covered Classic Shell in the past, but it’s come a long way since then. How Hackers Can Disguise Malicious Programs With Fake File Extensions Can Dust Actually Damage My Computer?

  • How do I stop icons appearing on the desktop under conky?

  • Where are the systray icons for Dropbox in Ubuntu desktop 13.04 (minimal)?

    - by samvv
    I reinstalled Ubuntu desktop using the minimal CD image and the following command: $ sudo apt-get install ubuntu-desktop --no-install-recommends After that I used Ubuntu Software Center to make sure Unity supports application indicators: http://i.imgur.com/bYF162w.png. Everything works great, except for Dropbox. For some reason the icon doesn't appear in the tray, even though the application is running. Steam on the other hand runs just fine, so it seems like there is nothing wrong with the tray itself. According to this post the tray icons should be in /usr/shared/icons/hicolor/22x22/status but it doesn't contain any Dropbox icons. Neither do any of the other resolutions. The answer is a bit outdated, so I'm not entirely sure it is still applicable to the current version of Dropbox. I did the usual thing of reinstalling dropbox with: sudo apt-get purge nautilus-dropbox sudo apt-get install nautilus-dropbox But that didn't solve anything either. Does somebody know how to fix this issue?

I don't think I need it anymore.... so do I delete it? or do I keep it? Is there a folder I should specificaly use for compiling? thanks for answering those newbies question.

  • How do I reset the default icons from the desktop icons?

    - by Jens Reubsaet
    I know this question sounds cryptic, but what I mean is this: I set different icons for the 'home' and mounted volumes on the desktop, but I want to revert that action. How do I do that? I already tried to do it from the icon selection dialog by clicking revert, but no effect. How do I restore this? (the desktop icons are from the default GNOME Icon Theme but I have the Faience icon theme: these do not really match up). Thanks in advance! I'm running Ubuntu-GNOME 13.04 64-bit (GNOME 3.8.2) I set the icons by right clicking, clicking the icon and selecting it by the dialog.

  • Is it possible to have my desktop loaded before login?

    - by Dims
    I am connecting to the system with Putty (this is Windows SSH client) then running some service in interactive personal mode. For example this is a script to run freeswitch: dims@nebulla:~$ cat freeswitch.sh #!/bin/sh cd ~/bin/freeswitch/bin gnome-terminal -e ./freeswitch & I.e. it is installed in user directory. Also DISPLAY is set to :0 The problem is that I can't use this script until login once. Script responds with dims@nebulla:~$ ./freeswitch.sh dims@nebulla:~$ No protocol specified Failed to parse arguments: Cannot open display: After login, I can do "Switch user" and see login screen but script will be able to run since desktop exists. My question is: is it possible to "preload" my desktop, so that initial situation was as if I loogged in and the went to switch user?

  • How can I print-screen just one window and not my entire desktop?

    - by Michael Durrant
    I could swear I've always been able to do alt-printscreen to get 'just that window' but right now I am getting my entire desktop. Any idea why this would be or what I can do to get my ability to do small window screen shots? I've tried a lot of combination with the ctrl, alt, shift and print-screen keys but no luck, nothing happens in response. One option: shift-ctrl print-screen lets me do a selection using a cross hair to size out the screen capture but I don't know where this gets saved. I'm not being given the choice and it's not in Desktop or Pictures. I use an external keyboard, but I've tried using the laptop's own keyboard and no difference. I am running Ubuntu 12.04 and the laptop is a Samsung Ultrabook 900 Update: I rebooted and it "fixed" it - for now. However this is not the first time I've seen this so I'm still curious as to why it happens, what I can do to fix w/o reboot and if other share the same problem.

  • How to install ubuntu from desktop w/o internet access?

    - by Tom P.
    I am trying to install ubuntu on a netbook without a CD drive. I first attempted a flash drive, but it did not work, so I decided to use the flash drive to transfer the application that can install from the desktop. However, this is a secondhand school computer that needs its borderline spyware security suite wiped before it can access the internet, so I cannot use the install from desktop application. Do I have any other options? I do have access to an external CD drive that I could try, but I am unconvinced that I would get different results since it would have to go through a USB port. Any and all input is very much appreciated!

  • How can I make my Java desktop application to run on different computers in a network locally and updating same mysql database?

    - by JaMpa
    I have developed Java desktop application for registration of students in the computer laboratories in our college, but what I need is to make this application whenever it runs on any computer (Windows XP machines) on the laboratory each and every data filled by the college students goes to the same MySql database (through WAMP server) running on the server machine (Win Server 2003). Also, I need this application to run during booting of windows computers in the laboratory for the purpose when any student tries to switch on any PC in the comp lab before interfacing the desktop icons should sign in through user name and password when he has already registered or signing up in order for getting the access.

  • How to make show desktop work only on the current workspace?

    I am an active user of workspaces in Ubuntu. Until recently, pressing Ctrl+Alt+D (show desktop) acted only on the current workspace. For example, one might want to minimize the applications in the current workspace, open a file, and then bring some of them back. The current implementation works on all workspaces uniformly which is counter-intuitive to me. The reason for the existence of workspaces is the separation of logic -- one can have a browser open in one workspace, a text editor in another, a terminal in a third. The current functionality goes against this idea. Is there a way to restrict the action of the show desktop command to a single workspace only?
