• Using MonoDroid, how can I open a dialog when an EditText field gains focus?

  - by Kiada

  I made the EditText clickable but you have to "double-click" to bring the dialog box up, which isn't really desired behaviour. How can I bring the dialog box up when the EditText is clicked / gains focus? Bonus points for including a way to stop the keyboard popping up :) _createProfileDobEdtTxt.Clickable = true; _createProfileDobEdtTxt.Click += (sender, e) => { ShowDialog(DATE_OF_BIRTH_DIALOG); };

• Drawing single pixel in Quartz

  - by wwrob

  I have an array of CGPoints, and I'd like to fill the whole screen with colours, the colour of each pixel depending on the total distance to each of the points in the array. The natural way to do this is to, for each pixel, compute the total distance, and turn that into a colour. Questions follow: 1) How can I colour a single pixel in Quartz? I've been thinking of making 1 by 1 rectangles. 2) Are there better, more efficient ways to achieve this effect?

• Connecting GPS coordinates taken from a database in Android using Overlay

  - by LordSnoutimus

  I am currently building an application that allows users to track where their phone has been on a Google Map. At the moment, when the onLocationChanged() method is called, the application stores the current GPS longitude and latitude in a database and calls the animateTo() method to the current position. Using SDK 1.5, how would I go about connecting these points with a coloured line drawn on the MapView using an Overlay?.

• Visual Studio: Debuggin non localhost domain, locally

  - by Skawful

  I have an entry in my hosts file that points somesite.com to 127.0.0.1 (localhost) so that I can test certain aspects of my web app (i goto http://somesite.com in a browser to test). Can someone suggest a way to debug a setup like this (in visual studio) that does not include using http://localhost? I understand that this can most likely be done using remote debugger, if that is the best way can someone explain how thats setup (or a link to a good article).

• Restarting an activity in a single tab in a TabActivity?

  - by user291701

  Hi, I have a TabActivity. Each tab points to a sub activity. Works great. Is there any clever way to refresh one of the activity tabs? I just want to 'restart' the activity in tab #3 for example. Not sure of a good way to do this other than building in refresh support to the activity itself, or clearing ALL the tabs and recreating all of them. Thanks

  Hello, I can easily draw the projection of a 3D set of points onto the plane with normal vector (1,1,1), by using the matrix (-sqrt(3)/2 sqrt(3)/2 0) (-1/2 -1/2 1). I want to do the same thing, but for a projection onto an arbitrary plane with normal vector (a,b,c) instead of (1,1,1). How to find the matrix? Thanks in advance!

• What Patterns Should I Consider For a Html Widget Generator?

  - by DaveDev

  I'm looking to see if I can design a HtmlHelper extension method that will generate the Html for different types of widgets I want to produce. Each different type of widget implements functionality to get and prepare any data it needs to render. Can anyone suggest any patterns I could refer to for approaches to take? I know there are probably frameworks available that will do this for me, but I thought I'd give it a try anyway. Any points of advice? Thanks

  Is there a way to capture the exact collection of pixels/points on the screen that are currently making contact with the users? I assume there is since this finger painting app shows the ipad responding to only the pixels that the user makes contact with. Thanks so much in advance for your help!
