  • Silverlight Binding: User controls inside datagrid.

    - by Eric
    I have a DataGrid in my silverlight app that has a few columns. A couple basic columns bound with no issues. One column has a UserControl in it and the XAML is as follows: <data:DataGridTemplateColumn Header="" CanUserSort="True" Width="107"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <local:StaticPageEnlistment EnlistmentName="{Binding SiteName}" Width="400" Height="150"/> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> </data:DataGridTemplateColumn> So I have a public property that's a string called EnlistmentName that I have bound to the SiteName value. I use this same "{Binding SiteName}" in all my other colums with no issues, why can't the user control accept the same binding string?

  • Warn user when new data is inserted on database

    - by João Menighin
    I don't know how to search about this so I'm kinda lost (the two topics I saw here were closed). I have a news website and I want to warn the user when a new data is inserted on the database. I want to do that like here on StackOverflow where we are warned without reloading the page or like in facebook where you are warned about new messages/notifications without reloading. Which is the best way to do that? Is it some kind of listener with a timeout that is constantly checking the database? It doesn't sounds efficient... Thanks in advance.

  • VB.NET custom user control graphics rotation

    - by AtharvaI
    Hi, this is my first question on here. I'm trying to build a dial control as a custom user control in VB.NET. I'm using VS2008. so far I have managed to rotate image using graphics.rotatetransform . however, this rotate everything. Now I have a Bitmap for the dial which should stay stable and another Bitmap for the needle which I need to rotate. so far i've tried this: Dim gL As Graphics = Graphics.FromImage(bmpLongNeedle) gL.TranslateTransform(bmpLongNeedle.Width / 2, bmpLongNeedle.Height * 0.74) gL.RotateTransform(angleLongNeedle) gL.TranslateTransform(-bmpLongNeedle.Width / 2, -bmpLongNeedle.Height * 0.74) gL.DrawImage(bmpLongNeedle, 0, 0) As I understand it, the image of the needle should be rotated at angle "angleLongNeedle" although i'm placing the rotated image at 0,0. However, the result is that the Needle doesn't get drawn on the control. any pointers as to where I might be going wrong or something else I should be doing? Thanks in advance

  • Warn user of .NET Framework requirements

    - by moogs
    So I have an app (tool) that uses .NET 3.0. When run on a machine that only has .NET 2.0 (like the default Server 2008 R2 install) it crashes miserably. What I've seen so far is that people are using a shunt that will first check the .NET version. Is there a way to build it or add some manifest somehow so that the user is warned of this problem (and hopefully be prompted to install .NET)? I know this can be solved by an installer, but I have requirements that need it to be a standalone executable.

  • Login screen using user custom control

    - by Mocco
    Hi, I have followed some advices I got here today and would need a bit more help now: I have an user control with login logic. In mainForm I am using this: private void Form1_Load(object sender, EventArgs e) { LoginScreen login = new MainMenu(); login.Parent = this; login.Dock = DockStyle.Fill; login.Show(); } But I guess it is not modal and thus does not stop the original Form application. Sure I would need the main Form to do not continue until the login form is closed (and login sucessfull). Would using an event correct? Let login object to raise an event that login was successfull and let the MainForm handle it - run the app?

  • Ruby and jQuery -- $(document).ajaxSend() not modifying the params as expected

    - by Jason
    I cannot get jquery's ajaxSend (http://api.jquery.com/ajaxSend/) to properly modify the parameters. I have: $(document).ajaxSend(function(event, request, settings) { settings.data = $.deparam(settings.data); settings.data['random'] = new Date().getTime(); settings.data['_method'] = 'get'; settings.data = $.param(settings.data) $.log(settings); }); $(document).ready(function() { //...snip... $.ajaxSetup({ data : { remote : 1, authenticity_token : encodeURIComponent(AUTH_TOKEN) } }); }); The idea here is that we always want 4 param sent across: remote and auth_token always get set properly. However, random and _method (both needed for IE issues) do not get set. Logging settings inside ajaxSend shows me that they are set to settings.data: "remote=1&authenticity_token=6GA9R_snip_253D&random=1270584905846&_method=get" but when it gets sent across the wire, I only have the following: authenticity_token 6GA9R_snip_253D remote 1 Why in the world is this not working?

  • drupal hook just before inserting/updating user info

    - by Senthil
    Hi, I want to hook into drupal's user registration and be able to stop it or allow it to proceed just before database insert. All validations and 3rd party stuff must be done and just before inserting I need to hook in. What is the hook and the operation to do this? I tried 'validate' operation in the hook_user. But, after I check against my logic and let the registration proceed, it should not fail due to some other validation. If I let it proceed, no application logic after that should stop the registration (unless the DB engine fails or something of course). If I stop it, I will set a form error so that nothing happens. How can this be accomplished? P.S. I am using Drupal 6.16

  • Use currently logged-in user in query

    - by Degan
    I am using VisualWebDeveloperExpress2008 with Access as the membership provider. I have some cases where I want users to edit their own data. This would involve a query where the UserId should equal the UserID of the user who is using the site. I am expecting to use WHERE UserId = ?, but I have not found out where to direct "?". The IDE gives several choices, but I am uncertain which to choose. This, while it looks promising does not work: <SelectParameters> <asp:ProfileParameter Name="UserID" PropertyName="UserId" Type="Int32" /> </SelectParameters> What is best to use for the Select Parameter?

  • PHP Readfile() number of bytes when user aborted

    - by jtnire
    Hi Everyone, I'm using a PHP script to stream a live video (i.e. a file which never ends) from a remote source. The output is viewed in VLC, not a web browser. I need to keep a count of the number of bytes transferred. Here is my code: <?php ignore_user_abort(true); $stream = $_GET['stream']; if($stream == "vid1") { $count = readfile('http://127.0.0.1:8080/'); logThis($count); } function logThis($c) { $myFile = "bytecount.txt"; $handle = fopen($myFile,'a'); fwrite($handle,"Count: " . $c . "\n"); fclose($handle); } ?> However it appears that when the user presses the stop button, logThis() is never called, even though I've put in ignore_user_abort(true); Any ideas on what I'm doing wrong? Thanks

  • Where does Ubuntu Software Center store its (language) settings?

    - by guntbert
    On a fresh install (13.04) I see a strange mix of languages in Software Center The menu (like my system language) is in English, but the descriptions are in German. I want the descriptions in English too. I am using a german keyboard and have German installed too (for giving support to students with German as system language :-)) In system settings I have moved German below English - so it should be ignored, I have logged out after that. I have cleared the "Software Center Cache" with Ubuntu Tweak. The picture remains the same.

  • use of views for validation of an incorrect login-id or an unidentified user

    - by sqlchild
    I read this on msdn: Views let different users to see data in different ways, even when they are using the same data at the same time. This is especially useful when users who have many different interests and skill levels share the same database. For example, a view can be created that retrieves only the data for the customers with whom an account manager deals. The view can determine which data to retrieve based on the login ID of the account manager who uses the view. My question: For the above example , i would have to have a column named Userid/LoginId on my table on which the view is created so that i can apply a check option in the view for this column. and then if a user with a name not in that column tries to enter data , then he/she is blocked.

  • User Defined Class as a Template Parameter

    - by isurulucky
    Hi, I' m implementing a custom STL map. I need to make sure that any data type (basic or user defined) key will work with it. I declared the Map class as a template which has two parameters for the key and the value. My question is if I need to use a string as the key type, how can I overload the < and operators for string type keys only?? In template specialization we have to specialize the whole class with the type we need as I understand it. Is there any way I can do this in a better way?? What if I add a separate Key class and use it as the template type for Key? Thank You!!

  • Getting access to a custom Master page from a user control

    - by Bernard
    Hi We have created a Master page that inherits off the asp.net Master class. We have also got ui controls that inherit off the standard asp.net ui control class. Our Master page has a public member variable. We need to be able to access that member variable from the ui controls that we use. However we can't seem to get at it? Is it our architecture that is wrong? Or the idea itself - user control getting acces to Master page variables?

  • Get rid of all user data of Android application after bigger update

    - by Johe Green
    Hi, I completely revamped an app. Tested it for a while on my device and emulator. The app worked fine. However when I updated the app through the Android market, my users experienced crashes. Since there is no way to properly debug this procedure I asume the crash is caused by old data which is not being removed from the device (probably from the onsavedstate bundle?!). Is there a way to do a "clean/total" reinstall without having the user to do it manually? Best Regards Johe

  • Activiti Engine: Task Event - User is null

    - by sockeqwe
    I have a problem, which should be simple to solve, but i can't find the method to call to solve this problem: My problem is, that every Task Event (org.activiti.engine.task.Event) returnes null by calling Event.getUserId(); If I take a look into the database I see that the database table ACT_HI_COMMENT has null as value for the column USER_ID_ for every row. I generate these TaskEvents programmatically by calling (for example) processEngine.getTaskService().addComment(task.getId(), null, commentMessage); processEngine.getTaskService().addUserIdentityLink(task.getId(), user.getId(), IDENTITY_LINK_OBSERVER); I guess there is a simple method that I must call to solve this problem, something like processEngine.setCurrentUser(authenticatedUser.getId()); Any suggestions?

Would the .click() event be triggered in this case as well?

  • Running Services.msc as a different User C#

    - by Simon Mark Smith
    Hi, I have a requirement to create a simple windows forms application that allows an admin user to manage the Services on remote servers. We don't want to give the admins the usernames and passwords to the servers so these will be encrypted and stored in a database. My question is whether or not it is possible to spawn a Services.msc window when impersonating one of the users stored within the database? I have looked at the ProcessStartInfo class but because Services.msc is not an executable it does not seem to like executing this. Any ideas on a simple way of doing the actual impersonation and loading of Services.msc - say off a button click? Thanks

  • How to create unique user key

    - by Grayson Mitchell
    Scenario: I have a fairly generic table (Data), that has an identity column. The data in this table is grouped (lets say by city). The users need an identifier in order for printing on paper forms, etc. The users can only access their cites data, so if they use the identity column for this purpose they will see odd numbers (e.g. a 'New York' user might see 1,37,2028... as the listed keys. Idealy they would see 1,2,3... (or something similar) The problem of course is concurrency, this being a web application you can't just have something like: UserId = Select Count(*)+1 from Data Where City='New York' Has anyone come up with any cunning ways around this problem?

  • 403 Forbidden for web root on Apache on Mac OS X v10.7, but can access user directories

    - by philosophistry
    When I access http://localhost/ I get 403 Forbidden, but if I access http://localhost/~username it serves up pages. Things I've tried: Checking error logs Swapping out with original httpd conf files Changing DocumentRoot to my user directory (after all that should work if I can access ~username) I've seen 30 plus Q&A sites that all point to people having trouble with user directories being forbidden. I have the opposite problem, and so I'm tearing my hair out here.

  • SQL query: Number of comments posted in last 24 hours by people a user is following

    - by bflora
    I've got a site where users follow users they like and can read their latest updates. I'd like to show my users a simple count of how many comments the people they follow have posted in the last 24 hours. I'm having trouble figuring out the query. I have two tables. comment -cid (comment id) -timestamp -uid (id of person who posted the comment) -comment (content of the comment) user_relationships -requester_id (id of the user who followed the person) -requestee_id (id of the person who was followed) In plain english, I think the query is something like this: COUNT the cid.comment from the comments table where uid.comment is equal to requestee_id.user_relationships associated with requester_id.user_relationships value of X. I need to get all the UIDs of people being followed by a given UID from the user_relationship table. Then count up how many comments those people have posted in the last 24 hours and spit that number out. What would this query look like?

  • C#.NET Reload configuration settings from an external config file during run-time.

    - by user569850
    I'm writing a game server in C#.Net and would like to reload or refresh settings from a config file while the server is running. Ideally I would like to save the settings in an XML file, have the ability to edit the file while the game server is running and then send the server the command to reload the settings from the file. I know I can use a database to do this as well, but the game server is fairly small and I think it would be more practical to just save settings in a flat-file. I will have file-level access to the machine the server will run on. What should I use?
