• Connect two UIScrollView's together

  - by johnw188

  Here's a tricky iPhone problem I've been working on. I have three UIScrollViews on a page, one that only scrolls horizontally, one that only scrolls vertically, and one that scrolls both horizontally and vertically. I want to lock the views together, so that the horizontal location of the horizontal only scrollview matches the horizontal location of the main scrollview, and the vertical scrollview likewise, so that dragging the main scrollview around controls the horizontal and vertical scrollviews. Problem is, I'm completely stumped. I've looked around inside the apple documentation, but there doesn't seem to be any way to do this officially. One thought that I had was to somehow "clone" any touch on any of the scrollviews to a point on the other two, but I have no idea how to do this. If anyone has any thoughts on this, I'd very much appreciate it.

• How to find out who's causing an access violation error?

  - by Fernando

  I'm getting reports that my app is causing a GPF on some Vista machines. The error message is something like this: access violation at 0x75784062 ( tried to write to 0x00000006) In order to fix this, I first need to know exactly who is causing this GPF: my main exe, some third party component, one of my own activex components, a dll, etc... How can I find this out? What tools can pinpoint the exact module that caused this mess? Any help would be greatly appreciated. PS My app is coded in VB6 and my activex controls are written in Delphi 2007.

• UI not redrawing after display powered off on Win 7

  - by oltman

  Some portions of my application's interface are not getting refreshed after Windows 7 powers down the display. More specifically, I'm swapping out images, User Controls, and a button's content while the display is powered off and after it has been restarted, and this isn't being reflected in the UI until I minimize and restore the window or move it to one of the screen's edges. I've tried calling the Window's InvalidateVisual() method when the app was in a state where it needed to redraw, and that didn't solve the problem. I have only been able to reproduce this issue on Windows 7. Any ideas?

• Selenium: How to enter white space as the value of a text field?

  - by Andrew

  I have a form text field that is being populated with a default value. I would like to clear the value and enter white space to assert that the expected validation occurs. I am using Selenium RC and the PHPUnit Selenium extension. How can I achieve this? Note: I have already tried doing these, but they do not work: $this->type('FirstName', " "); //spaces $this->type('FirstName', "\t"); //tab character They clear the value from the field, but they do not enter the white space into the field.

• Problem with usercontrol scaling when added at run-time in .Net, WinForms

  - by Jules

  First here's the steps to replicate, then I'll explain what the problem is: (1) Add a usercontrol to a form in the construtor, after the InitializeComponent call. (2) Run the form. (3) Click a button to increase the form font size. All the controls within the usercontrol scale perfectly but the usercontrol itself doesn't. It's width and height are increased by way too much. To correct the problem, the usercontrol must be added before the InitializeComponent call. If it wasn't possible for me to add the usercontrol before InitializeComponent, is there any way for me to correct the scaling?

  - by Sune

  Im looking for a (free) solution to a bookingcalender. Among many candidates Ive found the Jquery Full Calender which has many cool features. One of the reason that I like this one is because it has "drag and drop" and resize, which I also need. But I also need to have the dayview where I the columms monday, tuesday, wedensday, thursday friday .... gets replaced with fx. Room1, Room2, Room3, Room4, Room5, Room6, Room7.

Ive read others who has raised the same quistion on: http://code.google.com/p/jquery-week-calendar/issues/detail?id=35 but with no final solution. Are there any out there who has or knows some good links for want Im looking for?

• How can I clear the cache in an Outlook client pro grammatically?

  - by Curtis Inderwiesche

  I am executing the following routine often in order to clear the local cache of many Outlook clients (Outlook 2003) in order to fix corrupted Forms stored on the users local drive. On the Tools menu, click Options, and then click the Other tab. Click Advanced Options. In the Advanced Options box, click Custom Forms. In the Custom Forms box, click Manage Forms. In the Forms Manager box, click Clear Cache. Is there a way I can program this to occur on the local client? I am looking for a solution that could be included in Outlooks VBScript in order to include it in yet another 'Organizational Forms Library' Forms client side validation code. Would this question better fit Server Fault Stack Exchange via an admin script/tool?

• Designing a WPF map control.

  - by Dylan

  I'm thinking about making a simple map control in WPF, and am thinking about the design of the basic map interface and am wondering if anyone has some good advice for this. What I'm thinking of is using a ScrollViewer (sans scroll bars) as my "view port" and then stacking everything up on top of a canvas. From Z-Index=0 up, I'm thinking: Base canvas for lat/long calculations, control positioning, Z-Index stacking. Multiple Grid elements to represent the maps at different zoom levels. Using a grid to make tiling easier. Map objects with positional data. Map controls (zoom slider, overview, etc). Scroll viewer with mouse move events for panning and zooming. Any comments suggestions on how I should be building this?

• How can I hide the taxonomy field for authenticated users but show it for other users in Drupal 6?

  - by Jaymie

  I have a Drupal (v6.17) Content Type which includes a Taxonomy field. I want to hide this from ordinary Authenticated Users, but want it available to my Site Contributor role users, so they can review and then assign tags to user-created nodes. I've tried overriding the Node Add/Edit form in Panels 3 by creating a panel variant especially for Authenticated Users, which would exclude the Taxonomy field. However, the Taxonomy field is bundled in with the "General Form" controls - without showing this, I don't get the Title and Body fields. Is there a way I can either include the Title and Body fields without Taxonomy, OR hide just the Taxonomy field when the authenticated user role creates a node. I realise there's a CCK field which might be able to help me out here, but how do I tie that to the Taxonomy module? Any help gratefully received.

• Cannot loop through Excel 2003 files in SSIS 2008

  Hi, I am trying to execute a SSIS 2008 package on a 64-bit OS and import Excel 2003 files to SQL Server 2008.

• DataBinding and ErrorProvider - How to provide custom error messages?

  - by BeowulfOF

  We use BusinessObjects, implementing IDataErrorInfo and IEditableObject. BindingLists with those Objects are added to BindingSources, those are used to bind UserControls and DataGrids on the forms (WinForms). The BindingSource is additionally set as DataSource to the ErrorProvider of the form. We do use currently TextBoxes for Properties of Type int and short. They are validated inside the BusinessObjects with custom validation, like min/max values, etc. That works fine, since error message form our custom validations show up nicely next to the TextBox. However, if the input is greater than the value of an int (e.g. "9999999999") the BindingSource doesn't even try to enter that Value into the BusinesObject but instead gives the errormessage to the errorprovider like "The value for Int32 was too big.". We do not want to bother our users with "Int32" but want a custom errormessage for that. It is nice, that the BindingSource does provide this feature, but is it possible to provide custom error messages for this?

• Custom Validator with an OR Condition

  - by zSysop

  Hi all, Right now i have an asp.net 2.0 app which allows a user to search by the following fields Location (Required if there is nothing in idnumber field) Address (Required if there is nothing in idnumber field) Zip (Required if there is nothing in idnumber field) **OR** IDNumber. (Required if there is nothing in any of the other fields) What i'd like to be able to do is validate this client side on button click and display a summary of errors. i.e. if a user leaves every criteria blank. I'd like to display "You must enter a IDNumber or "Location, Address, and Zip to continue" I've never used the Custom Validation control so here are some questions. 1) Is it able to do this? 2) Does anyone have an example of how to do this? Thanks

• Localization with separate Language folders within Views

  - by Adrian

  I'm trying to have specific folders for each language in Views. (I know this isn't the best way of doing it but it has to be this way for now) e.g. /Views/EN/User/Edit.aspx /Views/US/User/Edit.aspx These would both use the same controller and model but have different Views for each language. In my Global.asax.cs I have routes.MapRoute( "Default", // Route name "{language}/{controller}/{action}/{id}", // URL with parameters new { language = "en", controller = "Logon", action = "Index", id = UrlParameter.Optional }, // Parameter defaults new { language = @"en|us" } // validation ); This works ok but always points to the same View. If I put the path to the Lanagugage folder it works return View("~/Views/EN/User/Edit.aspx"); but clearly this isn't a very nice way to do it. Is there anyway to get MVC to look in the correct language folder? Thanks and again I know this isn't the best way of doing Localization but I can't use resource files.

• How should the View pull on the Presenter in the MVP pattern

  - by John Leidegren

  I have a ASP.NET Web Forms application and I'm using some dynamic controls in the view which depend on stuff that the presenter exposes. Is it okay for the view in this case to pull on the presenter for that data? Is there anything I should be extra careful about when considering testability and a loosely coupled design. The page in this case has it's own page-life cycle and the presenter doesn't know about this. However, the page-life cycle dictates that somethings must occur at specific moments in the page-life cycle. This smells like trouble... Any known pit falls?

• How to remove one instance of one string in PHP?

  - by Jane

  I have a open source editor on the cms that I am making that automatically inserts a <br /> tag at the beginning of the post it submits to the database. This makes validation a pain, since even though there is no real text being submitted, the form still accepts the break tag as input and prevents the "Please enter some text" error from showing. So I tried to remove the opening break tag by filtering my input like this: substr($_POST['content'], 6); This works as long as the user doesn't press the backspace a couple of times which removes the break tag in which case the first 8 characters of the post gets removed even if they are not a break tag. So how can I remove the first 6 characters of the input ONLY if those first 6 characters are composed of the break tag. Also I don't want to remove all break tags, only the one at the very beginning of the post.

• ASP.NET control event handler not firing on postback?

  - by Polaris878

  I have a control which has an ImageButton which is tied to an OnClick event... Upon clicking this control, a postback is performed and the event handler is not called. AutoEventWireup is set to true, and I've double checked spelling etc.... We haven't touched this control in over a year and it has been working fine until a couple of weeks ago. We have made changes to controls which load this control... so I'm wondering, what kind of changes could we have made to stop this event handler from being called? There is quite a bit of Javascript going on, so this could be the culprit too... Edit: Some clarification... we are dynamically loading the parent control of the ImageButton in the OnLoad event of the page... if that makes sense.

• How to make a 3D UI for an application ?

  - by wacky_coder

  I'm building an application and I'd like its User Interface to be 3D, most probably a cylinder. The user would see the cylinder[Horizontally laid] and the cylinder's curved surface would have the buttons and any other controls that need to be placed. The cylinder needs to rotate and later, I'd like to add some other effects to the cylinder too. Someone told me that such a UI can be modelled using Maya or Blender and exported to openGL and then I could use C/C++ (with Qt) to carry out the actions. How can this be done?? Is there any other way to build the UI and do all the other things that I need ?? I really need some help because I have the UI in mind, but no idea on how to implement it. Thanks

• Make a connection to a HTTPS server from Java and ignore the validity of the security certificate

  - by justinhj

  I've been testing some that works with a bunch of https servers with different keys, some of which are invalid and all of them are not in the local key store for my JVM. I am really only testing things out, so I don't care about the security at this stage. Is there a good way to make POST calls to the server and tell Java not to worry about the security certificates? My google searches for this have brought up some code examples that make a class to do the validation, that always works, but I cannot get it to connect to any of the servers.

• jQuery .queue() not working as expected

  - by Andrew

  The page in question is right here: http://s289116086.onlinehome.us/lawjournaltv/index.php I'm 90% of the way there, I'm just assuming there's an error with my syntax. Focus on the blue callout area with "Workers' Compensation" as the title: Basically, I've created a little slideshow there with the controls at the top and when you click on any of them both the callout and the background are to slide. As you can see it's working now, but the problem is that I want the new background to slide in over the old one. I've tried several things including the queue() method, delay(), and adding everything else to the animate() callback with no success (right now the background goes black and then the new image slides in). You guys have never let me down before, so I'm hoping this is an easy fix. Thanks in advance!

• How do I convert a windows forms app from C# to VB ?

  - by SLC

  I've been converting all kinds of other things, classes, interfaces, ASP.NET MVC apps, and WPF applications, but I am stumped as to how to convert a windows forms application, as the whole structure seems to be different. Does anyone have any advice on how to tackle this problem? I see essentially that you have two files, Form1.cs and Form1.Designer.cs. Literally translating them from C# to VB doesn't work because of some intricacies or other of how Visual Basic works. I think you /might/ be able to convert Form1.cs in this way, as it's just a constructor plus event handlers, but the designer contains the references to the controls etc. and I am not sure how to go about doing that. I am using Visual Studio 2010 Beta 2.
