ASP.NET AJAX UpdatePanel problem

- by Velika

I'll try and be concise: 1) I have a dropdownlist with Autopostback set to TRUE 2) I have an UpdatePanel that contains a Label. 3) When the downdownlist selection is changed, I want to update the label. Problem: Focus is lost on the dropdownlist, forcing the user to click on the dropdownlist to reset focus back to the control. My "solution": In the DropDownList_SelectionChanged event, set focus back to the drop down list: dropdownlist1.focus() Problem: While this works great in IE, Firefox and Chrome change the scroll position such that the control which was assigned focus is positioned at the bottom on the visible portion of the browser window. This is often a very disorientating side effect. How can this be avoided so it works in FF as it does in IE?

OpenGL ES view: how to orient it to landscape?

- by Steph Thirion

Looking for clues about orienting an OpenGL ES app in landscape, most information I found dates back from 2008, most of it refering to the early versions of the SDK. Apparently, back in the days, in the case of GL it was recommended to not rotate the view, but instead to apply the rotation as a GL transformation. Is it still the case with the current SDKs? It would be so much simpler to simply rotate the window: all the touch events would be in sync with the rotation. In other words: how to set up an OpenGL view in landscape mode?

Getting Tap/Touch Position when selecting a TableView cell

- by Omer

Hi, hope to get some help here because this is something that really makes me mad... I have a view with a tableView, and when I tap a cell I want to present a popOver window pointing the arrow to the cell I tapped. the things that I think I need is: 1- the position of the cell in the screen (not in the view, because on large tables the Y value of the cell's rect could be grater than screen hight) or 2- a CGPoint or something similar that represents the point in the screen I tapped. I can't figured this out, and makes me really mad!!! Any help will very very very very usefull. Have a nice day.

Debug.WriteLine not working

- by Velika

In the past, perhaps versions of Visual Studio prior to the 2008 that I am using now, I would do something like this in my VB.NET code: System.Diagnostics.Debug.WriteLine("Message") ..and the output would go to the output window. Now it doesn't. Something must first apparently be enabled. If this involves "attaching a debugger", please explain how to do it. It seems to me that it should just work without too much of a fuss. Here's a video explaining the issue in real time and showing you all my settings http://screencast.com/t/YQnPb0mJcs I'm using VS2008

Visual Python - Visualize graphs relating to a movement

- by Francisco P.

Hello, everyone! I'm working with visual python on a project where I need to simulate a physical movement. I'd like to present, in a different window than the one the actual, 3D sim is running, two graphs, both related to the movement: How the velocity and angular velocity progress over time. How the movement and rotation progress over time. All these vars are refreshed once per cycle (inside a while(true)) How can I accomplish this? Thank you for your time!

OTA plist app install from within phonegap app for iPad

- by Farhan Ahmad

I am trying to initiate a OTA app install from within a phonegap iPad app. I have tried this: var url = "http://www.example.com/test.plist"; window.open("itms-services://?action=download-manifest&url=" + url, "_blank"); This works in iOS 5 but NOT iOS 6. I have also tried using the ChildBrowser plugin to point to a page with a link to the OTA app install but that doesn't work either. (If I visit the webpage directly from within the native iPad browser, it works fine) Does anyone know how I can initiate a OTA app install from within the phonegap iPad app? (must work in iOS 5 and iOS 6) I am trying to implement an auto update feature within a Ad-Hock iPad app (not through App Store). So when the app detects that there is a new update, it will prompt the user to install the new update and thats where I need this functionality.

How to install Oracle Weblogic Server using OS-specific Package installer?(Windows)

- by PratikS -- Oracle

Note: OS-specific Package installer As the name suggests the installer is platform specific. It is meant for installation with a 32bit JVM only. Both SUN and JROCKIT 32 bit JDKs come bundled with "OS-specific Package installer", so no need to install the JDK in advance. There are three different ways of installing Oracle Weblogic Server: Graphical mode Console mode Silent mode For Windows: 1) Graphical mode:Installer: wls_<version>_win32.exe (E.g. wls1036_win32.exe)Steps to Install:1) Log in to the Windows system.2) Go to the directory that contains the installation program.3) Double-click the installation file.(wls1036_win32.exe)As soon as you double-click on the installation file you wold see the following screens: Once the installation preparation is complete you will see the welcome screen: Click Next If there are existing Middleware Home Directories it will list all of them. You may either select an existing Middleware Home Directory or create a new one. Note: It is always recommended to have one Middleware Home Directory per installation, so I'll select "Create a new Middleware Home" Click Next If you want to register for Security updates enter your My Oracle Support credentials or else un-check the box, it will prompt to bypass click Yes and then click Next. Click Next Again Click Next Click Next to All Users to access the Oracle Weblogic Server Installation. Click Next ( Make sure the more then 1289.8 MB of space is available in the Middleware Home) Wait for the installation to complete. Click Done. And the installation is complete. 2) Console mode: Log in to the target Windows system. Open a command prompt window. Go to the directory that contains the installation program. Launch the installation by entering the name of the installation program.

How to make Visual Studio Pause after executing a console app in debug mode?

- by Jason Dagit

I have a collection of boost unit tests I want to run as a console application. When I'm working on the project and I run the tests I would like to be able to debug the tests and I would like to have the console stay open after the tests run. I see that if I run in release mode the console window stays up after the program exits, but in debug mode this is not the case. I do not want to add 'system("pause");' or any other hacks like reading a character to my program. I just want to make Visual Studio pause after running the tests with debugging like it would if I were running in release mode. I would also like it if the output of tests were captured in one of Visual Studio's output windows but that also seems to be harder than it should be. How can I do this? Thanks!

Avoid painting over nested controls

- by Cobus Kruger

I am writing a toolbar-style control and use the ThemeServices unit to paint the background required by the toolbar. Like so: ThemeServices.DrawElement(Canvas.Handle, ThemeServices.GetElementDetails(trRebarRoot), ARect); I then drop child controls onto the toolbar and voila - instant toolbar. Except that every now and again I notice that the nested (child) controls don't repaint as well. So my control paints its background and the child controls disappear until you move the mouse over them. Some of the edit controls show their client area (no border) and some of them are just gone altogether. This happens mostly when I place a window from another application over the toolbar and move it away. I keep thinking this has to be very easy to cure, that perhaps I'm somehow preventing the paint message from reaching the child controls, or missing an override but I have been unable to figure it out.

Very unusual and weird problem with gVim 7.2

- by Fabian

After installing gVim and running gvim from the run window, if I were to type :cd followed by a tab, I will get \AppData, \Application Data, etc. Which basically means I'm at my $HOME directory (C:\Users\Fabian). The weird thing is I do not have a \Application Data folder there. But if I were to run gvim.exe from its installation folder, and I type :cd followed by tab, I would get \autoload, \colors, etc. which means I'm at the installation folder. And if I were to pin gvim.exe on to taskbar, upon launch and typing :cd then tab, I will get \Dictionaries and upon hitting tab again I get a beep. I think for the last scenario, I'm at some Adobe folder. Anybody knows how to fix this weird issue? I'd like to pin it to taskbar and upon launch, start in the $HOME directory (C:\Users\Fabian).

getSelection & surroundContents across multiple tags

- by lethalbody

Hi, I've got a script that changes the background colour of text that has been selected. However i'm encountering an issue when the text is selected across multiple elements/tags. The code that i've got is: var text = window.getSelection().getRangeAt(0); var colour = document.createElement("hlight"); colour.style.backgroundColor = "Yellow"; text.surroundContents(colour); And the error being output is: Error: The boundary-points of a range does not meet specific requirements. = NS_ERROR_DOM_RANGE_BAD_BOUNDARYPOINTS_ERR Line: 7 I believe this is to do with the getRange() function though i'm not too sure how to proceed since I am a beginner at javascript. Is there any other way I can replicate what I am trying to achieve? Many thanks.

Artistic aspects of UI?

- by anon

Consider a single button. At one extreme, we have a black OpenGL window, with: outline (in white) of a rectangle bitmap remdered font inside of it, saying "Ok" At the other extreme, we have Mac OS X, a button that is: well rounded has some gradient showing light effects on it nice antialiased "OK" soft shadow of some sort These two UIs present very very different user experiences. The former says "This is from the 80s" the latter says "this is professional". This is something I do not understand well as a programmer (and don't know where to learn about this). Does anyone know of a good technical resource for this? [I'd prefer things that draws upon psychology / perception literature to say why to do something rather than design books that just says "use color XYZ with a gradient of blah"]

HTML/CSS layout question

- by TheDelChop

Guys, I just need a little help with some CSS layout if you don't mind. I've got three things I'm trying to play around with and I need some help making this work the way I was hoping. I've got the element of a page, which I'd like to be 100% of the browser window, obviously. Then I've got two elements which I'd like to stack on top of each other, but the trick is this, I'd like the bottom div, (a menu which should really be a fixed height) to determine the height of the top div. Is there a way to lay this out in CSS?

Hiding UIToolBar for child views of UITableViewController

- by Robin Jamieson

My main controller is a subclass of UITableViewController with a UIToolBar at the bottom and when a row is selected, I'd like to display another view without the toolbar. How can I hide the UIToolBar in the child view? Right now, it's present throughout all child views unless they're created as modal. Toolbar is created in RootController: self.toolbar = [[UIToolbar alloc] init]; // add tool bar items here [self.navigationController.view addSubview:toolbar]; RootController displays its child views as such: UIViewController *controller = [[UIViewController alloc] init...] [self.navigationController pushViewController:controller animated:YES]; RootController is instantiated as such in the app delegate's applicationDidFinishLaunching: RootController *rootcontroller = [[RootController alloc] initWithStyle:UITableViewStyleGrouped]; self.navigationController = [[UINavigationController alloc] initWithRootViewController:rootcontroller]; [rootcontroller release]; [window addSubview:[self.navigationController view]]; If I add the toolbar to [self.view] within RootController instead of navigationController's view, the toolbar disappears alltogether..

ASP.NET ASPX Designer question. Bug?

- by Velika

Check out this Screenshot. Shouldn't a hierarchy list of tags appear here? Usually it appears. Sometimes, the tag "appears" there but without text (but the tag object is there as evident when you hover over it.) Other times, like this, nothing appears. It's a usual feature to see the hierarchy or tags which gives me easily access to the tags from design view for easy altering in the properties window. I think too many developers love to do things the hard way and sludge thru tags in HTML view and hardly use this, but it frustrates me when it doesn't work all the time. Is it me? Nah....

load images dynamically on scroll in blackberry

- by Maneesh

How to display images in the form of pages where only one page is displayed at a time on blackberry screen. On scrolling down subsequent images will load at run time. So that loading of images do not consume time at startup. Edit: I am using loadimage function which loads images from blackberry device memory which loads images from specified path and resizing them.As number of images increases, it increases the startup time during opening of window.There is an in-built application(Media) in blackberry phone, where images load without taking any extra time. My idea is to display particular number of images which fit to the blackberry screen. As user scroll down to bottom of screen, application will then load and display more images. So my question is how to detect when user reached to bottom of blackberry screen and display one more row images.

XCode 3.2 - can't create Objective-C class

- by Urizen

My installation of XCode 3.2 has begun to exhibit some strange behaviour. When I try to add a basic Objective-C classs (inheriting from NSObject), in my iPhone project, I get the following popup: "Alert. Couldn't load the next page". The above-mentioned error happens at the point of trying to create the file (i.e. the creation process doesn't get to the stage where you are asked to input the file name). It might also be worth mentioning that where there previously used to be a description for the file (in the file creation window) it now states "No description available". I can create other files (e.g. UIViewController subclass etc.) but not the basic Objective-C class. I have updated the documentation and restarted the machine and xcode several times without success. I would be extremely grateful for any assistance as I am relatively new to the XCode environment.

.NET StandardInput Sending Modifiers

- by Paul Oakham

We have some legacy software which depends on sending keystrokes to a DOS window and then scraping the screen. I am trying to re-create the software by redirecting the input and output streams of the process directly to my application. This part I have managed fine using: _Process = new Process(); { _Process.StartInfo.FileName = APPLICATION; _Process.StartInfo.RedirectStandardOutput = true; _Process.StartInfo.RedirectStandardInput = true; _Process.StartInfo.RedirectStandardError = true; _Process.StartInfo.UseShellExecute = false; _Process.StartInfo.CreateNoWindow = true; _Process.OutputDataReceived += new DataReceivedEventHandler(_Process_OutputDataReceived); _Process.ErrorDataReceived += new DataReceivedEventHandler(_Process_ErrorDataReceived); } My problem is I need to send some command modifiers such as Ctrl, ALT and Space as well as F1-12 to this process but am unsure how. I can send basic text and I receive response's fine. I just need to emulate these modifiers.

textbox supplied route values with javaScript

- by Maslow

I've tried the bare method and the T4MVC method but so far both are routing me to the current URL instead of the default path with no arguments for the following action: public virtual ActionResult Index(byte? location, int? sublocation) { } So when I try Url.Action("Index","Locations", new {location="", system=""}) if I'm at a location already this method returns the path to where I'm already at instead of the default path with no arguments. As does the following method with T4MVC. <input type="button" value="Go" style="display:none" onclick="window.location='<%= Url.Action(MVC.Controller.Index()) %>/'+$('input#location').val()+'/'+$('input#sublocation').val()+'/';" /> How can I get the default route with no arguments?

Why is Standard Input is not displayed as I type in Mac OS X Terminal application?

- by BryanWheelock

I'm confused by some behavior of my Mac OS X Terminal and my Django manage.py shell and pdb. When I start a new terminal, the Standard Input is displayed as I type. However, if there is an error, suddenly Standard Input does not appear on the screen. This error continues until I shut down that terminal window. The Input is still being captured as I can see the Standard Output. E.g. in pdb.set_trace() I can 'l' to display where I'm at in the code. However, the 'l' will not be displayed, just an empty prompt. This makes it hard to debug because I can't determine what I'm typing in. What could be going wrong and what can I do to fix it?

Simple example of popup authentication with Facebook Graph API

- by ensnare

Trying to get Facebook to authenticate my users via a javascript popup. Right now, I have: <input type="button" value="Connect with Facebook" onclick="window.open('https://graph.facebook.com/oauth/authorize?client_id=XXXXXXXXXXX&redirect_uri=http://example.com/step2&display=popup')" /> But when the user logs in via Facebook, the popup just displays the Facebook.com homepage. I'd like for the popup to authenticate the user and go away so that I can start retrieving user data from the graph api. Is there a better / easier way to do this? Simple examples are appreciated. Thank you.

Problem with javascript in firefox when moving google ads

hi. i have a website with google ads on it. i would like to make it load faster. thus i moved all the google scripts to the bottom of the page. i also have a placeholder at the location where the ad(s) should be displayed and other divs that (initially) get the ads. finally (in window.onload) i'm moving the ads that have just be fetched from google to their target locations.

[or at least, not in a reliable way.]) any ideas what would be causing this? Thanks! -thomas woelfer
