  • Touch screens for kiosk applications

    - by Micah
    I'm developing a kiosk-style touchscreen application in Qt. Currently I'm using an Elo Touch surface acoustic wave touchmonitor which works well except for one thing: drag performance is way too poor to provide a good user experience. As this is the case for the cursor in X as well as in my application, it seems to be either the fault of X (probably not) or the touchmonitor. Since mobile platforms are able to achieve very high performance in this regard, it seems like it should be possible for vastly more powerful desktop systems. Does anybody have experience with getting good drag performance out of desktop touchmonitors? What hardware have you used? Is X to blame?

  • Silverlight 4 Out-of-browser application into the browser ?

    - by Niklaos
    Hi guys, I just lost 5 hours looking for a answer which i haven't been able to find :p First, I'd like to force a trusted application (i need to access the file system) to display into the browser. Based on what i found on google a trusted application must be installed and launched as a desktop application (also called out-of-browser application). So, i want to have an installed application on the client side but meanwhile, the user must also be able to start this same application into a browser window when he goes on my web site. Is this possible ? Second, I'd like to give to the user the possibility to start the application from the browser. To be clear be the application is installed on the client computer but i want a button on my web site which starts the desktop application. How can i do that ? Thanks

  • How do I bring Set Focus of MDI Child Window using UIAutomation

    - by Scott Ferguson
    We have an old legacy application we need to automate. It uses MDI Windows. We're using UIAutomation and I can succesfully get the appropriate AutomationElement for each MDI Child window. What I cannot do is bring that element into focus. Here is some example code that I tried, that fails: var desktop = AutomationElement.RootElement; var dolphin = desktop.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Dolphin for Windows", PropertyConditionFlags.IgnoreCase)); dolphin.SetFocus(); var workspace = dolphin.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Workspace", PropertyConditionFlags.None)); var childWindow = workspace.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Sharp ")); childWindow.SetFocus(); The last line in this code fails with System.InvalidOperationException Experimenting, I tried finding a control on the childWindow, and calling SetFocus on it. It DID correctly set the focus on the right control, but it did not bring the MDI window to the foreground. Any ideas?

  • Dropdown menus not showing when i use my wpf application via Remote connections

    - by Bijoy Das Yesudas
    When i connect to my machine using remote desktop the dropdown menus and comboboxes i used in my wpf application is not showing up. And after closing the session when i comes back to my development machine where actually my application runs there also the same issue happens after the remote desktop session. Tried by changing resolution and all sometimes it works but most of the time result is negative. The only temporary solution i found for this is just rebooting the system which is not applicable. Could anyone please help me to fix this issue. Thanks in advance.

  • How to develop a DirectFB app without leaving X.11 environment.

    - by Edu Felipe
    Hi folks, I'm trying to develop a GUI application for an embedded platform, without any windowing whatsoever and I'm doing that with DirectFB, and it suits my needs very fine. Since the embedded I develop for is not that powerful, I would really like to try to develop on my own Ubuntu desktop. The problem is Framebuffer is conflicting with X.org causing me to leave the whole desktop, and shutdown X.org just to see the result of my changes. Is there a good framebuffer simulator that suits my needs? Qt has one, called QVFb, but it only works for developing Qt apps, and the VNC back-end of DirectFB always crash. So, any ideas?

  • How to launch a file protocol URL with an anchor from Java?

    - by Jeff C
    From a Java program, I need to launch the default browser on a local HTML file, pointed to an anchor inside the file. In Java SE 6, the java.awt.Desktop.browse method will open the file, but will not honor the anchor, so something like the following opens the file at the top, but does not page the browser to the anchor: Desktop.getDesktop("file:///C:/foo/bar.html#anchor"); Sun says here http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6477862 that anchors are not supported in the file URI protocol. Does anyone have a better answer? I can use Java SE 6. I would be OK with a Windows only solution.

    - by sujit
    I have created on image uploader as a desktop application. Now I want to port it to Android using Monodroid. Application uploads images to dropbox. In the desktop version I have used "dropnet" which references "sharpbox", "Json", etc. Is there any way I can use those i.e. dropnet, sharpbox, etc in my monodroid app? It will take very long if I have to recode those libraries already available in .net . thanks. Sujit

  • Run Windows XP on a usb drive virtually on Windows XP?

    - by Russell
    I am sick of not being able to run and install certain applications on my work computer due to admin restrictions (eg: Adobe AIR) . I have heard of smaller versions of Windows running on a usb thumb drive and have looked into it but can't find anything on running windows virtually from a usb drive. I would like to be able to login to this particular computer, insert my usb drive and then open up another version of windows installed on the thumb drive while still being able to use the windows I logged in on (literally be able to alt+tab between the main desktop and the virtual desktop from the usb drive). Is this even possible? For further clarification: The version of windows has to be Windows XP and there is no other option available for what I want to do. Looking forward to a response.

  • Computer Quiz Management Software

    - by Asad Jibran Ahmed
    My university is holding a quiz contest in 2 weeks, and I need some sort of software (desktop or web based) that can be used to manage the quiz. I need functionality like an admin panel for adding teams, creating matches between 2 teams, adding questions and answers. I then need the software to automatically display the questions, accept answers, and display and store results. Is there any software (open source/freeware) that I can use for this task. If a pre-built software is not available, which language+library+platform would you suggest I make the software in. It can be either web based or a desktop app. But I need it by 2 weeks. Any suggestions?

  • Javascript callback on blackberry

    - by Jeff
    I'm working on a mobile project, and I have a script that is dynamically generated on the backend and then appended to the document (the html page). Desktop browsers seem to append the script correctly and call any functions in the script, however, I can't get this to happen on Blackberry phones. I know that the script is being appending because I can alert it after I append it. I just can get it to call the function in the script. For example, if I have code like this: var scriptText = document.createElement('script'); scriptText.type = 'text/javascript'; scriptText.id = 'thisScript'; scriptText.innerHTML = 'alert("hello");'; document.getElementById('idName').appendChild(scriptText); alert(document.getElementById('thisScript')); //Alerts the script element. This will alert 'hello' in desktop browsers and even the iPhone/iPodTouch, but not BlackBerry's. Anyone have any idea why? Or if there's a fix/hack?

  • Do not compile t4 file

    - by brian b
    Suddenly, after doing a TFS 2010 get, Visual Studio 2010 is attempting to compile my .tt file as if it was c#. Moreover, anytime I set it to "Build Action=None", Build Action gets mysteriously reset to Compile. This is breaking our builds on the desktop. I can get builds to work on the desktop by closing then reopening VS. Our builds on TFS are totally broken because of this. What to do? The template generates a (totally ok) c# file, so I need the project to build. I tried changing the file extension from .tt to .donotbuilddammit but that had no effect.

  • Software Requirement Specifications for Web Applications

    - by illuminatedtiger
    Hi guys, I'm looking for some guidance/books to read when it comes to creating a software requirement specification for a web application. For inspiration I have read some spec documents for desktop based applications. The documents I have read capture a systems functional requirements in use cases which tend to be rather data oriented with use cases centered around the various CRUD operations the application is intended to perform. I like this structure however I'm finding it rather difficult to marry it to what my web application needs to do, mostly reading data as opposed to manipulating it. I've had a go at writing some use cases however they all tend to boil down to "Search for item", "Change view of search results" or "User selects facet to refine search results". This doesn't sound quite right to me and makes me wonder if I'm going about this the right way. Are there planning differences between web based and desktop based applications?

  • Intercept web requests from a WebView Flash plugin

    - by starkos
    I've got a desktop browser app which uses a WebView to host a Flash plugin. The Flash plugin makes regular requests to an external website for new data, which it then draws as fancy graphics. I'd like to intercept these web requests and get at the data (so I can display it via Growl, instead of keeping a desktop window around). But best I can tell, requests made by Flash don't get picked up by the normal WebView delegates. Is there another place I can set a hook? I tried installing a custom NSURLCache via [NSURLCache setSharedURLCache] but that never got called. I also tried method swizzling a few of the other classes (like NSCachedURLResponse) but couldn't find a way in. Any ideas? Many thanks!

  • Using psftp to upload and download files

    - by macha
    Hello I am trying to upload and download files from my desktop to my server. Now after some search I did download psftp. I used to use filezilla earlier, but I cannot install it on my desktop due to a few reasons. Since psftp (similar to putty) is just an executable for file transfer. So now after going through this link http://www.math.tamu.edu/~mpilant/math696/psftp.html. I understood that put and get are two commands I would use to download and upload files. Now when I logon to the server and say get filename, it actually is throwing back an error "local: unable to open filename". I tried that with other files too, and I end up getting the same error. Am I making a mistake or is it a problem with this executable? I did not find relevant tags for this topic, could somebody suggest me the right forum for this issue.

  • Windows Azure Queues, WCF, MSMQ integration

    - by user104295
    Hi there, I have a scenario where I need a desktop console app to communicate with a Windows Azure Queue... the most important thing is that the message is received by the server eventually. Also, the desktop app may be disconnected from the Internet sometimes. In the traditional WCF+MSMQ approach you'd be able to send a message which would be cached in MSMQ until MSMQ could reach the Server's MSMQ and send the message. What's the equivalent when Windows Azure is the server-side? Is it possible for the same approach to be used, where MSMQ just communicates with a Windows Azure Queue rather than an MSMQ on a Windows Server? Maybe Windows Azure Queue is the wrong approach? I have heard about something called message buffer, but don't know what this is (yet!). thanks for your help Kris

  • Should I be so enthusiastic about Groovy?

    - by rukoche
    I'm currently working on my project which consists of front and back-end written in PHP and desktop app written in Java, and that's what the plan was before I discovered Groovy and later on Grails. Now after rewriting my desktop client and sketching some back-end functionality in Groovy I'm considering to drop PHP altogether in favor of Groovy (although I haven't played around with Grails yet.) For me it just looks like coding in Groovy is as simple as in PHP, but with lots of extra sugar and awesomeness of Java libraries. Comparing those two may sound awkward, but hey I'm an amateur ;) Finally to my question, from the looks of it most of the articles/blog posts about Groovy I can find is awfully outdated. Am I missing some reason why it's not so popular and which will crush my enthusiasm to bits? :D

  • What is IPKVM and why would I need that to install SQL Server on my Web Server?

    - by Eric
    Hello. I have a dedicated server, and will be installing SQL Server. However, my hosting company said they can connect an external CD ROM drive and give me KVM over IP to install SQL Server. My question is, what is IPKVM, and how does it work? Do I need special hardware or software on my side to use it....or do I just connect via remote desktop? Also, why can't I remote into my server through remote desktop instead of using KVM over IP?

  • How do I create a Launcher in Ubuntu 9.1 that runs a shell script?

    - by mkelley33
    Here's my situation: New to Ubuntu (just nstalled 9.10 Karmic Koala 64 bit) Purpose: to easily run PyCharm without too much typing (ie. cd... ./pycharm.sh) Want to create desktop Launcher instead of terminal & typing (without resorting to the "Run in Terminal" option) Tried to create Launcher to executes .sh script in Document directory Right-clicked Desktop Create Launcher a. Type == Application; Browse [insert absolute path to .sh script]; no luck b. Type == Application in Terminal; Browse ...ditto I'm open to any other alternatives that involve as little typing as possible. I would like to just start Ubuntu, click Launcher icons, and have terminals spring to life, running the intended scripts. Crazy? No. Lazy? Probably. Productive? Hopefully :)

  • Where do I start ?

    - by Panthe
    Brief History: Just graduated high school, learned a bit of python and C++, have no friends with any helpful computer knowledge at all. Out of anyone i met in my school years I was probably the biggest nerd, but no one really knew. I consider my self to have a vast amount of knowledge on computers and tech then the average person. built/fixed tons of computers, and ability to troubleshoot pretty much any problem I came across. Now that high school is over, Ive really been thinking about my career. Loving, living computers for the past 15 years of my life I decided to take my ability's and try to learn computer programming, why I didn't start earlier I don't know, seems to be big mistake on my part... Doing some research I concluded that Python was the first programming language I should learn, since it was high level and easier to understand then C++ and Java. I also knew that to become good at what I did I needed to know more then just 2 or 3 languages, which didn't seem like a big problem considering once I learned the way Python worked, mainly syntax changed, and the rest would come naturally. I watched a couple of youtube videos, downloaded some book pdf's and snooped around from some tutorials here and there to get the hang of what to do. A two solid weeks had passed of trying to understand the syntax, create small programs that used the basic functions and understanding how it worked, I think i have got the hang of it. It breaks down into what ive been dealing with all this time (although i kinda knew) is that, input,output, loops, functions and other things derived from 0's and 1's storing data and recalling it, ect. (A VERY BASIC IDEA). Ive been able to create small programs, Hangman, file storing, temperature conversion, Caeser Cipher decode/encoding, Fibonacci Sequence and more, which i can create and understand how each work. Being 2 weeks into this, I have learned alot. Nothing at all compared to what i should be learning in the years to come if i get a grip on what I'm doing. While doing these programs I wont stop untill I've done doing a practice problem on a book, which embarresing enough will take me a couple hour depending on the complexity of it. I absolutly will not put aside the challenge until its complete, WHICH CAN BE EXTREMELY DRAINING, ive tried most problems without cheating and reached success, which makes me feel extremely proud of my self after completing something after much trial and error. After all this I have met the demon, alogrithm's which seem to be key to effiecent code. I cant seem to rap my head around some of the computer codes people put out there using numbers, and sometimes even basic functions, I have been able to understand them after a while but i know there are alot more complex things to come, considering my self smart, functions that require complex codes, actually hurt my brain. NOTHING EVER IN LIFE HURT MY BRAIN....... not even math classes in highschool, trying to understand some of the stuff people put out there makes me feel like i have a mental disadvantage lol... i still walk forward though, crossing my fingers that the understanding will come with time. Sorry if is this is long i just wish someone takes all these things into consideration when answering my question. even through all these downsides im still pushing through and continuing to try and get good at this, i know reading these tutorials wont make me any good unless i can become creative and make my own, understand other peoples programs, so this leads me to the simple question i could have asked in the beginning..... WHERE IN THE WORLD DO I START ? Ive been trying to find out how to understand some of the open source projects, how i can work with experianced coders to learn from them and help them, but i dont think thats even possible by the way how far people's knowledge is compared to me, i have no freinds who i can learn from, can someone help me and guide me into the right direction.. i have a huge motivation to get good at coding, anything information would be extremely helpful

  • WCF large message exception

    - by Saurabh Lalwani
    Hi, I have a web service which is returning data to the desktop application. The problem I am having is, when the web service returns small volume of data everything works fine but when the volume of data is large it throws the following exception: System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. Can it be because it is taking a good 4-5 seconds to fetch all the records from the database and the session times out or something? Also, when I am debugging the web service, I see that this particular method is called twice and it is also returning the correct value both times, but for some reason the desktop application seems to be throwing the aforementioned exception. I found similar posts before on stackoverflow but they did not solve my problem. Can anybody please tell me what's going on in here? Thanks!

  • Limit the model data fields serialized by Web API based on the return type Interface

    - by Stevo3000
    We're updating our architecture to use a single object model for desktop, web and mobile that can be used in the MVVM pattern. I would like to be able to limit the data fields that are serialized through Web API by using interfaces on the controllers. This is required because the model objects for mobile are stored in HTML5 local storage so don't carry optional data while a thin desktop client would be able to store (and work with) more data. To achieve this a model will implement the different interfaces that define which data fields should be serialized and there will be a controller specific to the interface. The problem is that the Web API always serializes every field in the model even if it is not part of the interface being returned. How can we only serialize fields in the returned interface?

  • How to make Inno Setup ignore the hidden attribute while searching for files?

    - by andi
    I have to copy into the installer folders containing hidden files (in my case Desktop.ini). I use a line similar to this one in the [Files] section: Source: "folder\*desktop.ini"; DestDir: "{app}\folder"; Flags: recursesubdirs uninsneveruninstall; Attribs: hidden This line only works if I remove the hidden attributes. If all are hidden, it complains that it could not find any files. How can I configure Inno to search for hidden files using patterns?
