  • Remove a toolbar when pushing a new view

    - by nevan
    In the iPhone maps app there's a toolbar at the bottom of the map view (it contains the Search/Directions segment control and others). When moving from the map view by clicking on a callout, the toolbar slides out with the map view, leaving the next view (a table controller) with no toolbar. I've tried to do the same thing with [self.navigationController setToolbarHidden:YES animated:YES] in the second view controller, but this gives a strange toolbar sliding down animation, while the map view is sliding to the left. Using [self.navigationController setToolbarHidden:YES] in viewDidLoad:animated also causes a bad effect (it makes the toolbar disappear the moment the push animation starts, leaving an ugly white space). I'm assuming the answer to this is to use a nib file, but I'd prefer to do it programatically (if possible). How can I get the toolbar to "stick" to the map view and slide out with it when I push a new view controller? Thanks.

  • When to use CreateChildControls() vs. embedding in the ASPX

    - by Kelly French
    I'm developing a webpart for SharePoint 2007 and have seen several posts that advise to do all the creation of controls in the code-behind. I'm transitioning from Java J2EE development so I don't have the platform history of .Net/ASP/etc. In other places it shows how you can do the same thing by embedding the control definition into the asp page with tags My question is this: What is the rule governing where to implement controls? Has this rule changed recently, ASP vs ASP.Net or ASP.Net MVC maybe? Is this advice limited to SharePoint development?

  • Simulating a mouse button click in Windows

    - by Ncarlson
    Hi everyone, I'm writing Remote Desktop clone in C++ using QT. So far I'm able to move the mouse cursor around fine. QT has a nice setPos function for that. However, I'm a bit lost as to what API/Library to use for simulating mouse button clicks. One method I'm aware of is to send the WM_(event) to a window using the window's HWND. However, I was hoping there was a more salient method for taking complete control over a mouse. Is there any other way to tell the operating system that the left mouse button has been clicked? Thanks.

  • Silverlight 4 desktop application sometimes zooms when touching it... and cannot zoom out

    - by TimothyP
    Hi, I have a Silverlight 4 desktop application which I control using a touchscreen (on an HP Touchsmart). Most of the time it works fine but sometimes when clicking something everything just zooms in and every time it happens things get bigger and bigger. The only way to get the normal size again is by restarting the application. Has anybody got any idea what might be causing it ? Does not seem to happen in browser mode. Is there a way to prevent zooming? Thnx

  • How to stop the execution of Java program from Command line?

    - by Aakash
    My main field is .Net but recently I have got something to do with Java. I have to create a shell utility in Java that could run in background reading few database records after specified duration and do further processing. It's a kind of scheduler. Now I have few concerns: How to make this work as a service. I want to execute it through a shell script and the utility should start running. Off course the control should get back to the calling script. Secondly, eventually i may want to stop this process from running. How to achieve this? I understand these are basic question but I really have no idea where to begin and what options are best for me. Any help / advise please?

  • With ASP .NET, how do I display a side submenu depending on what user picked from the main menu?

    - by Ole Media
    Hello, I come from PHP side, but I'm in need to develop a site using ASP .NET So far I manage to create a master page. Now I'm dealing with menus and submenus What I'm trying to do is, if the user picks "About Us" from the main menu, under the about us page I want to display a submenu with the options "who we are, what we do, contact us" If the user picks "Our Products" from the main menu, then under the products page I want to display a submenu with the options "product 1, product 2, product 3" Is this possible with only one master page? I read something about menu control but not sure that is what I need. So far I found how to display a sitemap, but not specific sections of a sitemap, if this is the way to do things. Any links, sample code, point of reference will be appreciated. Thanks

  • some OVERLAPS using WSASend not returning in a timely manner using GetQueuedCompletionStatus?

    - by Geoffrey
    Background: I'm using CreateIoCompletionPort, WSASend/Recv, and GetQueuedCompletionStatus to do overlapped socket io on my server. For flow control, when sending to the client, I only allow several WSASend() to be called when all pending OVERLAPs have popped off the IOCP. Problem: Recently, there are occassions when the OVERLAPs do not get returned to the IOCP. The thread calling GetQueuedCompletionStatus does not get them and they remain in my local pending queue. I've verified that the client DOES receive the data off the socket and the socket is connected. No errors were returned when the WSASend() calls were made. The OVERLAPs simply "never" come back without an external stimulus like the following: Disconnecting the socket from the client or server, immediately allows the GetQueuedCompletionStatus thread to retrieve the OVERLAPs Making additional calls to WSASend(), sometimes several are needed, before all the OVERLAPs suddenly pop off the queue. Question: Has anyone seen this type of behavior? Any ideas on what is causing this? Thanks, Geoffrey

  • How to build a Windows Forms email-aware text box?

    - by Patrick Linskey
    Hi, I'm building a C# client app that allows a user to communicate with one or more existing users in a system via an email-like metaphor. I'd like to present the user with a text entry box that auto-completes on known email addresses, and allows multiple delimiter-separated addresses to be entered. Ideally, I'd also like the email addresses to turn into structured controls once they've been entered and recognized. Basically, I'm modeling the UI interaction for adding users after Facebook's model. Are there any Windows Forms controls out there with the ability to do something like this? Is there any well-established terminology for a hybrid textbox / control list box (no, not a ComboBox) or something that I should be searching for? Thanks, -Patrick

  • Finding an HTTP proxy that will intercept static resource requests

    - by pkh
    Background I develop a web application that lives on an embedded device. In order to make dev times sane, frontend development is done using apache serving static documents, with PHP proxying out to the embedded device for specifically configured dynamic resources. This requires that we keep various server-simulation scripts hanging around in source control, and it requires updating those scripts whenever we add a new dynamic resource. Problem I'd like to invert the logic: if the requested document is available in the static documents directory, serve it; otherwise, proxy the request to the embedded device. Optimally, I want a software package that will do this for me (for Windows or buildable on cygwin). I can deal with forcing apache to do it with PHP, but I'm unsure how to configure it to make it happen. I've looked at squid and privoxy, but neither of them seem to do what I want. Any ideas? I'd rather not have to roll my own.

  • Tool used to retrieve code metrics in xUnit Test Patterns?

    - by leeand00
    I'm reading xUnit Test Patterns by Gerard Meszaros. On one of the pages he refers to some software metrics: While the need to wrap lines to keep them at 65 characters makes this code look even longer than it really is, it is still unnecessarily long. It contains 25 executable statements including initialized declarations, 6 lines of control statements, 4 in-line comments, and 2 lines to declare the test method—giving a total of 37 lines of unwrapped source code. Short of counting the statements to find these metrics, does anybody have any idea if he used a particular tool to calculate the metrics? (If you have any suggestions for tools that will count similar metrics, I'm looking for one that works on Java, Javascript and C++) Thanks!

  • Page validation not working in javascript

    - by crisgomez
    Hi, I have a problem regarding checking the page validation in javascript. I have a user controls in my aspx page,for example control1, control2, and control3. For each control I created a validation group, then I tried to use the code below, the problem is, it will always return a false value eventhough the page validation has been satisfied.What went wong with the code below?By the way I used Ajax in my application. if (typeof (Page_Validators) != "undefined") { if (typeof (Page_ClientValidate) == 'function') { Page_ClientValidate(); } if (Page_IsValid) { // do something alert('Page is valid!'); } else { // it will always goes here eventhough it was validated successfully alert('Page is not valid!'); } }

  • c# - clear surface when resizing

    - by dhh
    Hello, I'm trying to build my own custom control for a windows forms application in C#.Net. Currently I paint some rectangles and other graphic elements using the paint event. When I now resize the app form to fit the desktop size, all elements are repainted (which is exactly the behaviour I need) but the old one's are shown in the background. Here's what I'm doing by now: Pen penDefaultBorder = new Pen(Color.Wheat, 1); int margin = 5; private void CustomControl_Paint(object sender, PaintEventArgs e) { CustomControl calendar = (CustomControl)sender; Graphics graphics = e.Graphics; graphics.Clear(Color.WhiteSmoke); graphics.DrawRectangle(penDefaultBorder, margin, margin, calendar.Width - margin * 2, calendar.Height - margin * 2); //... } Neither the graphics.Clear, nor adding a graphics.FillRectangle(...) will hide the old rectangle from the surface. Ideas? Thank you all.

  • Jquery binding event on selected class

    Is it achievable in jquery to bind an event to a group of control that has certain class? It seems to me, it can't. I google a bit and all that came up are nothing to do with events. Here's how my code looks - $('.numonly').bind('keypress',function(event){ if (event.which > 31 && (event.which < 48 || event.which > 57)) return false; });

  • C# Thread issues

    - by Mike
    What I have going on is a listview being dynamically created from a previous button click. Then ti starts a background worker in which should clear out the listview and populate the iistview with new information every 30 seconds. I continously get: Cross-thread operation not valid: Control 'listView2' accessed from a thread other than the thread it was created on. private void watcherprocess1Updatelist() { listView2.Items.Clear(); string betaFilePath1 = @"C:\Alpha\watch1\watch1config.txt"; using (FileStream fs = new FileStream(betaFilePath1, FileMode.Open)) using (StreamReader rdr = new StreamReader((fs))) { while (!rdr.EndOfStream) { string[] betaFileLine = rdr.ReadLine().Split(','); using (WebClient webClient = new WebClient()) { string urlstatelevel = betaFileLine[0]; string html = webClient.DownloadString(urlstatelevel); File.AppendAllText(@"C:\Alpha\watch1\specificconfig.txt", html); } } }

  • Simple WCF question.

    - by bearrito
    So I am learning WCF and I have run across an issue that I believe has to do with Instance Control/State but I am not sure. Workflow is as follows, Basic client/server paradigm. The client calls a Method RetrieveBusinessObjects(criteria) and the server calls the datalayer and then puts them in an IList on the server side. It does not return this list to the calling Client. The client would then call a method say DisplayBusinessObjects() which would retrieve the IList from the Server, serialize them, bring them across the wire and display them. If i try this using the WCFTestClient it works. If I run it from an actual client then I get back an BusinessObject[] of size 0. Which to me indicates I had no objects to return. Is that a state mgmt issue or am I missing something?

  • Pass Value between MDI Child in WinForm using C#

    - by abhilashca
    I have an MDI Parent, containing a MenuStrip. When I click on one of the Menu, two Child Forms are displayed simultaneoulsy. I have a TextBox and a Send Button on one of my ChildForm. When I type-in something in that TextBox and Click the Send Button, I need to show that value in the TextBox of my Second Child Form. What I had done is, I wrote a Public Function in the Second Child Form and tried to invoke it by creating an object of Second Form, on the Send Button click event. When I put break points, in that Public Function, I find that the control is flowing through that Public function on cliking the Send button. But the passed value is not displayed. And, I know that is not the standard way to do that. Any sample script for help? Thanks.

  • ASP.NET Deploying websites

    - by Bridget
    I have some websites that use ImageMagick to convert images and place them in a created folder. Locally it all worked fine, but once I deployed it to my network's webserver it would not convert the images nor create the folders. My asp.net pages that read data from a database work. All the users have full control permissions over the site. I don't know if I need to modify the Web.config or some other permissions. Maybe it has to do with ImageMagick. I've just run out of ideas on what the problem could even POSSIBLY be. Any suggestions?

  • Disabling FileSystemWatcher for specific updates?

    - by chaiguy
    Does anyone have any ideas how I can reliably disable a FileSystemWatcher object when my application makes changes to the files in the directory, so that I am only watching for external changes to the directory? I've tried setting EnableRaisingEvents to false immediately before performing a write and setting it back to true immediately after, but it seems this method is not reliable, and occasionally I still get the event firing. The only other thing I can think of is to wait a small amount of time after performing the write to let the OS finish up the modification of the directory before re-enabling the FSW, but that seems hackish and I don't like it. To add to the problem, the directory consists of potentially many files, the identities of which are beyond my knowledge and control, so I can't just wait for the event to fire for a specific file and then ignore it. There could be any number of FSW events firing after a single modification (because of the potentially many files getting updated).

  • Change text_factory in Django/sqlite

    - by Krumelur
    I have a django project that uses a sqlite database that can be written to by an external tool. The text is supposed to be UTF-8, but in some cases there will be errors in the encoding. The text is from an external source, so I cannot control the encoding. Yes, I know that I could write a "wrapping layer" between the external source and the database, but I prefer not having to do this, especially since the database already contains a lot of "bad" data. The solution in sqlite is to change the text_factory to something like: lambda x: unicode(x, "utf-8", "ignore") However, I don't know how to tell the Django model driver this.

  • MySQL: Changing order of auto-incremented primary keys?

    - by Tom
    Hi, I have a table with a auto-incremented primary key: user_id. For a currently theoretical reason, I might need to change a user_id to be something else than it was when originally created through auto-incrementation. This means there's a possibility that the keys will not be in incremental order anymore: PK: 1 2 3 952 // changed key 4 5 6 7 I'm wondering whether this will cause problems, and whether MySQL reads something special to the incremental order of the keys, given that they should have come to existence in incremental order (which persists even when some rows are deleted). Assuming there are no associated foreignkey issues, or that these are under control, is there a problem with "messing with" the order of MySQL's autoincremented keys? Thank you.

  • What option in Visual Studio let catching exception where it occurred?

    - by macias
    VS 2010. The same WPF project, debug mode, two computers: A -- when exception occurrs the caret is placed at the point of exception B -- when the exception occurrs, correct exception is placed but always caret is placed at "win.ShowDialog()" in App.xaml.cs -- this is main entry for showing & running my application, in such case it is very tiresome to track down where the exception occurred What kind of settings control such behaviour? Of course I would like to switch B, so when exception hits I would be place at the point of exception, not at the main entry.

  • How can i create a submitable form that contains dynamically added and removed controls

    - by bill
    Hi All, I am trying to create a form that is made up of controls with values that represent an entity with multiple child entities. The form will represent a product with multiple properties where the user will then be able to create options with multiple properties which in turn be able to create multiple option-items with multiple properties. My question is what is the best approach? Can i use ajax to avoid postbacks and having to rewrite the controls to the page? If i dynamically add the controls in the form of table rows or grid rows will the data/control values be available in the code-behind when i submit? This is an age old question.. the last time i had to do this was .Net 2.0, pre-ajax (for me) and i was forced to recreate all the controls on each post back. thanks!

  • NSSavePanel selecting part of file name

    - by regulus6633
    How do I set the part of the file name that is selected in NSSavePanel? I only want the file name selected and not the file extension. Here's what I noticed. If I setAllowedFileTypes: for the save panel then only the file name is selected but not the file extension. However if I don't set the allowed file types then the file extension is selected along with the file name. I don't want to use setAllowedFileTypes but I still want to control the selection so that the file extension is not selected. Can that be done?

  • VB.NET 2.0 - StackOverflowException when using Thread Safe calls to Windows Forms Controls

    - by LamdaComplex
    I have a Windows Forms app that, unfortunately, must make calls to controls from a second thread. I've been using the thread-safe pattern described on the http://msdn.microsoft.com/en-us/library/ms171728.aspx. Which has worked great in the past. The specific problem I am having now: I have a WebBrowser control and I'm attempting to invoke the WebBrowser.Navigate() method using this Thread-Safe pattern and as a result I am getting StackOverflow exceptions. Here is the Thread-Safe Navigate method I've written. Private Delegate Sub NavigateControlCallback(ByRef wb As WebBrowser, ByVal url As String) Private Sub AsyncNavigate(ByRef wb As WebBrowser, ByVal URL As String) Try If wb.InvokeRequired Then Dim callback As New NavigateControlCallback(AddressOf AsyncNavigate) callback(wb, url) Else wb.Navigate(url) End If Catch ex As Exception End Try End Sub Is there a Thread-Safe way to interact with WinForms components without the side effect of these StackOverflowExceptions?
