  • Wait set time for user input C#

    - by Marlon
    I need to know how to wait at set amount of time (about 10 seconds), for a user to input a key or set of keys, before proceeding with an 'auto run' portion of the application. This is bugging me because I can't quite figure out how the timer works, or threading.sleep, what should I use? Been googling all day.

    I have a form validation message for the user name field which says the following Name can only contain alphabets, '.' and ' ' characters OR should it be Name can only contain alphabets, dot and space characters OR should it be Name can only contain alphabets, dot (".") and space (" ") characters Which is preferable from a usability perspective assuming the end users has very less exposure to computers.

  • Require User to be Logged in to Download ZIP Files

    - by Jonathan Wood
    Is it possible to require the user be authenticated (logged in) when downloading ZIP files from my site? Note that I don't have direct control of IIS7. (I'm on a shared hosting account.) I can't simply alter the access for a particular directory because many directories are involved and most contain other files that can be accessed freely. I've Googled this a bit and found similar questions. But I've been unable to find this exact question.

  • Validating entered user data

    - by msfanboy
    Hello, this is a general question but I do a desktop application. Should I check for example the firstname exceeding 50 chars or is this a matter of taste? Or should I check for 50 chars because the user could flood my database with 10000000 chars ?

  • Skip new Windows 7 user selection and go to login prompt

    - by Doltknuckle
    We've begun our migration to windows 7 and we ran into an interesting issue. When we hit "CTRL+ALT+DEL" we are brought to the "User selection Screen". Normally, this screen will have an icon for every local user for the machine. These machines are Domain members with "Fast User Switch" disabled so no user names are listed only the "Other User" option. If you click "Other User" or hit enter, the system moves on to the normal login screen where it prompts for user name and password. Here's the issue: We want to find a way to skip over the part where a user selects "Other User". We essentially want the system to always assume that we always want "Other User" and to go directly to the login screen when a user hits "CTRL+ALT+DEL". What I find odd is that the "Other User" doesn't show up until we've had more than one domain user log in. Right after we re-image the machine, the login process goes directly to the user credential prompt. Anyone have any ideas?

  • Quadratic bezier curve: Y coordinate for a given X ?

    - by stefan.at.wpf
    Hello, I have a quadratic bezier curve and I need the Y coordinate of a point on the bezier curve for a given X coordinate. I know that in pure maths this can be easily done, but I'm wondering is there's a simple / another way for this in C# / WPF? Is it possible to get the single points used by C# / WPF for drawing the bezier curve and then maybe just loop them and compare the X coordinate of each point with the given X coordinate? BTW for the mathematical way it would be good to know which step for the parameter t of the bezier curve has been choosen by C# / WPF? Any chance to find this out? Probably t is just scaled by / steps for t are 1/(distance of P0 and P2) ? Thank you very much for any hint!

  • User Management: Managing users in user-defined "groups", database schema and logistics

    - by Kevin Brown
    I'm a noob, development wise and logistically-wise. I'm developing a site that lets people take a test... My client wants the ability for a user with the roll/privledge "admin" (a step below a super-admin) to be allowed to create users and only see/edit the users that they create... The users created in that "category" or group need some information that their superior provides. For example, I log in as a "manager", I have the ability to invite people to take the test, and manage those people. Before adding those people, I will have filled out a short survey about myself... Right now, the users that are invited will be asked some of the same questions as the manager. I'd like to cut down the redundancy by using the information put into the database by the manager and apply it to the invited users. How do I set up my database to work with this criterion? I'm a little confused about how to do this! Let me know if I can add more details... (This is a mysql and php app)

  • How to programmatically start a WPF application from a unit test?

    - by Lernkurve
    Problem VS2010 and TFS2010 support creating so-called Coded UI Tests. All the demos I have found, start with the WPF application already running in the background when the Coded UI Test begins or the EXE is started using the absolute path to it. I, however, would like to start my WPF application under test from the unit test code. That way it'll also work on the build server and on my peer's working copies. How do I accomplish that? My discoveries so far a) This post shows how to start a XAML window. But that's not what I want. I want to start the App.xaml because it contains XAML resources and there is application logic in the code behind file. b) The second screenshot on this post shows a line starting with ApplicationUnterTest calculatorWindow = ApplicationUnderTest.Launch(...); which is conceptually pretty much what I am looking for, except that again this example uses an absolute path the the executable file. c) A Google search for "Programmatically start WPF" didn't help either.

  • WPF PasswordBox Input Panel Icon Not Appearing: Better Workaround?

    - by Anna Savarin
    Hello, There is a known issue in WPF where the Input Panel icon does not appear when you set focus on a PasswordBox control. I'm in need of a workaround for this, but the one suggested -- using the ITextInputPanel API -- does not quite cut it for me. Fist of all, the API works with Windows Forms controls and alternatively accepts control handles. Since WPF controls are not handle based, and they are not Forms controls, this is not quite suitable. I tried hosting a Forms control on my WPF page and that worked on the Windows XP Tabled PC (albeit with some COM exceptions) but, since there is no PasswordBox in Forms, I had to stick with a regular textbox, which is not what I need. Alternatively, using the VisualTreeHelper to get a handle on the control did not work, either. The API, according to http://msdn.microsoft.com/en-us/library/ms699559%28VS.85%29.aspx, is only compatible with Vista. I'm dealing with Windows XP tablets. I understand that the IPenInput API can be used as an alternative, but it is now deprecated. Can someone please suggest something? I really need to fix this issue. Thanks in advance!

  • wpf progress bar slows 10x times serial port communications... how could be possible that?

    - by D_Guidi
    I know that this could look a dumb question, but here's my problem. I have a worker dialog that "hides" a backgroundworker, so in a worker thread I do my job, I report the progress in a standard way and then I show the results in my WPF program. The dialog contains a simply animated gif and a standard wpf progress bar, and when a progress is notified I set Value property. All lokks as usual and works well for any kind of job, like web service calls, db queries, background elaboration and so on. For my job we use also many "couplers", card readers that reads data from smart card, that are managed with native C code that access to serial port (so, I don't use .NET SerialPort object). I have some nunit tests and I read a sample card in 10 seconds, but using my actual program, under the backgroundworker and showing my worker dialog, I need 1.30 minutes to do the SAME job. I struggled into problem for days until I decide to remove the worker dialog, and without dialog I obtain the same performances of the tests! So I investigated, and It's not the dialog, not the animated gif, but the wpf progress bar! Simply the fact that a progress bar is shown (so, no animation, no Value set called, nothing of nothing) slows serialport communicatitons. Looks incredible? I've tested this behavior and it's exactly what happens.

  • 500 Metro Style WP7 Icons

    - by Bil Simser
    I was inspired by The Noun Project, a project that offers up “Metro-style” icons in SVG format. The project is licensed under a public domain license and while it’s a great project, all of the content is in SVG format. Jon Galloway has a great post (from 2007) talking about the differences between SVG and XAML so I highly recommend that for some background. I thought it would be helpful to the WPF/Windows Phone 7/Silverlight community to provide the content in alternative formats for use in your applications. The Goods I’ve put together a package of the 500 icons (502 actually) in PNG, XAML and the original SVG format along with a couple of sample projects so you can see them in action. There’s a WPF desktop app: And a Windows Phone 7 app: Building It To get all the content first I wrote up a quick program to suck the original SVG files. Luckily they’re all in a common path just named 1.SVG, 2.SVG, and so on. Easy sleazy to grab the contents. Once I had 500 SVG files I used the latest copy of XamlTune, an open source CodePlex project that has a command line conversion tool to convert the directory of SVG files into XAML (the tool also created a PNG file of each SVG so that’s just icing on the cake). Conversions The conversion from SVG to XAML isn’t 100%. While you can just drop the content into a WPF app, it doesn’t work that way for WP7. There are just some small adjustments I made to each format so you’ll have to do the same. Follow the information below or refer to the sample applications. As a sample, here’s an icon we want to use: Here’s the original SVG file: <svg version="1.0" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="100px" height="94.616px" viewBox="0 0 100 94.616" enable-background="new 0 0 100 94.616" xml:space="preserve"> <path d="M25.076,15.639c4.324,0.009,7.824-3.488,7.82-7.82C32.9,3.512,29.4,0.012,25.076,0c-4.313,0.012-7.814,3.512-7.821,7.819 C17.262,12.15,20.763,15.648,25.076,15.639L25.076,15.639z"/> <path d="M4.593,43.388h6.861l4.137-15.135h1.716L13.22,43.388h24.318l-4.389-15.135h1.817l2.32,7.415 c1.08,3.131,3.852,3.851,6.003,1.162l8.375-10.142c2.651-3.42-2.104-7.021-4.844-4.035l-4.993,5.952 c0.007,0.095-0.96-3.278-0.96-3.278c-1.135-3.978-4.918-7.903-10.595-7.922H19.576c-5.071,0.019-9.043,4.434-9.888,7.214 L4.593,43.388L4.593,43.388z"/> <polygon points="56.206,22.753 56.206,7.163 49.192,7.163 49.192,22.753 56.206,22.753 "/> <path d="M79.87,15.738c4.332-0.014,7.831-3.516,7.82-7.82c0.011-4.332-3.488-7.833-7.82-7.82c-4.306-0.013-7.806,3.488-7.821,7.82 C72.064,12.222,75.564,15.725,79.87,15.738L79.87,15.738z"/> <path d="M89.759,89.556v-43.19h5.751V22.804c0.007-3.079-2.757-5.448-6.71-5.449H70.436c-3.65,0.001-4.539,1.186-5.551,2.168 L49.597,37.889c-3.098,3.848,2.428,8.333,5.55,4.743L69.88,25.226v64.43c-0.019,6.475,9.06,6.686,9.081,0.201v-36.58h1.765v36.379 C80.748,96.109,89.772,96.13,89.759,89.556L89.759,89.556z"/> <polygon points="100,54.035 100,45.155 0,45.155 0,54.035 100,54.035 "/> </svg> Here’s the XAML that XamlTune created.

  • How to add LDAP user to existing local group in RHEL?

    - by Highway of Life
    I'm attempting to add some of our LDAP users to a locally defined group on our RHEL server, however I get an error stating that the LDAP user is not found in /etc/passwd. What would be the best way to allow LDAP users to be added to local groups? My feeling is that this must be done manually. I could edit: /etc/group and add the LDAP group to the list. Would that be ideal?

  • How to create a user account for a child in Linux Mint?

    - by zenstealth
    Recently I have renovated an old computer which once belonged to my dad (the old HDD crashed, and I just bought a new one to replace it). My parents want me to fix this computer for my 5-year-old sister to use. I decided to use Linux Mint as the OS because everything (flash, mp3, etc.) is already configured. How do I create a user account in Linux Mint with limited access for my sister, so that it won't mess up the entire system? All she does is surf the web, so I'm just worried that she might accidentally mess up a system setting that I eventually will have to fix it.

  • Attached Property port of my Window Close Behavior

    - by Reed
    Nishant Sivakumar just posted a nice article on The Code Project.  It is a port of the MVVM-friendly Blend Behavior I wrote about in a previous article to WPF using Attached Properties. While similar to the WindowCloseBehavior code I posted on the Expression Code Gallery, Nishant Sivakumar’s version works in WPF without taking a dependency on the Expression Blend SDK. I highly recommend reading this article: Handling a Window’s Closed and Closing Events in the View-Model.  It is a very nice alternative approach to this common problem in MVVM.

    i have an HP dm3t notebook which normally comes with windows 7. after some time i figured out how to install Windows XP on it. but now i am facing a problem that the brightess controls dont work so i am unable to change the brightess. the strange thing is that all the other buttons (sound volume, mute, sleep , etc... ) works but not the 2 brightess controls. i already downloaded the "HP Quick Launch Buttons" so i am asking about suggesitions how can i enable these two buttons in windows XP or even if i can change the brightess using some kind of software. thanks

  • Desktop speakers with headphone port and separate volume controls

    - by Kevin L.
    I currently use the excellent Logitech X-230 desktop speaker/subwoofer set, which I love for the volume dial on the front which gives me a nice, quick, tactile control of my sound without requiring a remote or keyboard buttons or some awkward software slider. Additionally, there's a very convenient headphone jack right next to the volume dial but the volume dial only controls the speakers, leaving the headphones at full volume. The goal is to be able to adjust the sound in my headphones without having to fumble around and find an inline headphone volume control (and my current favorite pair doesn't even have one). Is anyone aware of a desktop speaker set that has convenient volume controls for both levels?

  • Attempt to connect to wireless internet at home and i am asked for User Credentals, nothing I enter works

    - by lucig12
    I just got a new modem and am trying to connect my windows 7 desktop to the new wireless connection. I had no issues on the three previous connections I have used, but for some reason when I click on the icon for Wireless Network Connections, click on my network, it asks for User Credentials. Nothing I type in works. I have tried saving credentials in credentials manager, using my login info, using the network's login info, recreating the network manually, plugging and unplugging my modem, literally every solution on every forum for similar issues. I have no idea what to do now. any ideas?

  • Where does a Quick-Time powered application store changes to the user interface?

    - by Luke
    I have downloaded an application written with the Quick Time library (for Windows 7). The application does not need an installation: just unzip it in a directory and run the program. It works, but I have a problem: the program allows the user to change a lot of values using its interface but does not have an option to reset them to their default values. What is more problematic is that when I exit the program and run it again, the interface still has the changed values. In the program directory there is no file that stores the changes done to the UI of the program. I suspect that Quick Time records these changes somewhere, but I can't find the right file. I have even deleted the application and re-unzipped it to another location - but the UI values still remain the same values changed by me!
