• Firing MouseLeftButtonDown event programmatically

  - by RajenK

  Hi, I'm trying to manually fire a MouseLeftButtonDown event on a WPF control programmatically, as I am using the Microsoft Surface SDK, which does not fire MouseLeftButtonDown events, but ContactDown events. Basically I'm trying to push the MouseLeftButtonDown event down to the control, to fire off the correct behavior on the control, while handling a ContactDown event. I'm guessing I have to somehow use the RaiseEvent method on the control to do this with MouseButtonEventArgs, but I'm having some trouble figuring out the parameters. Thanks in advance for your help!

• Android HelloGoogleMaps to OSMdroid (Open Street Maps)

  - by birgit

  I am trying to reproduce a working HelloGoogleMaps app in Open Street Maps - but I have trouble including the itemized overlay in OSMdroid. I have looked at several resources but I cannot figure out how to fix the error on OsmItemizedOverlay - I guess I am constructing OsmItemizedOverlay wrongly or have a mixup with OsmItemizedOverlay and ItemizedOverlay? But everything I tried to change just raised more errors... "Implicit super constructor ItemizedOverlay() is undefined. Must explicitly invoke another constructor" "Cannot make a static reference to the non-static method setMarker(Drawable) from the type OverlayItem" - I hope someone can help me getting the class definition straight? Thanks so much! package com.example.osmdroiddemomap; import java.util.ArrayList; import android.app.AlertDialog; import android.content.Context; import android.graphics.Point; import android.graphics.drawable.Drawable; import org.osmdroid.api.IMapView; import org.osmdroid.views.*; import org.osmdroid.views.overlay.*; import org.osmdroid.views.overlay.OverlayItem.HotspotPlace; public class OsmItemizedOverlay extends ItemizedOverlay<OverlayItem> { Context mContext; private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>(); //ERRORS are raised by the following 3 lines: public OsmItemizedOverlay(Drawable defaultMarker, Context context) { OverlayItem.setMarker(defaultMarker); OverlayItem.setMarkerHotspot(HotspotPlace.CENTER); mContext = context; } public void addOverlay(OverlayItem overlay) { mOverlays.add(overlay); populate(); } @Override protected OverlayItem createItem(int i) { return mOverlays.get(i); } @Override public int size() { return mOverlays.size(); } protected boolean onTap(int index) { OverlayItem item = mOverlays.get(index); AlertDialog.Builder dialog = new AlertDialog.Builder(mContext); dialog.setTitle(item.getTitle()); dialog.setMessage(item.getSnippet()); dialog.show(); return true; } @Override public boolean onSnapToItem(int arg0, int arg1, Point arg2, IMapView arg3) { // TODO Auto-generated method stub return false; } }

• Print Alternating Characters From Two Strings (Interleaving) Using Recursion Java

  - by babi2balla

  I'm trying to write a method that uses recursion to print the string formed by "interleaving" the strings str1 and str2. In other words, it should alternate characters from the two strings: the first character from str1, followed by the first character from str2, followed by the second character from str1, followed by the second character from str2, etc. How would I go about this? Any ideas are greatly appreciated!! Thanks

• Spark show logged in user

  - by Jose

  How do I show the username of the person logged in within a Spark View? The default MVC view engine had a Page object that you could get the info from. How would I do that in spark? I know that I could put the info into the viewdata dictionary, which is probably the best, but I don't want to have to write ViewData["User"] = myUser; before I return from EVERY action method. I'd like some feedback

• C# function normal return value VS out or ref argument

  - by misha-r

  Hi People, I've got a method in c# that needs to return a very large array (or any other large data structure for that matter). Is there a performance gain in using a ref or out parameter instead of the standard return value? I.e. is there any performance or other gain in using void function(sometype input, ref largearray) over largearray function(sometype input) ? Thanks in advance!

• is there a way to disconnect from facebook login without calling logout

  - by Joey

  Basically, I'd like to know how I can logout of my facebook session if I am in an iphone app and have connected to facebook (such that I do not have to repeatedly enter my login/password). Normally you'd disconnect in the app somewhere like in the options, but if this is not available (i.e. anything that triggers the FBSession logout method) is there some other way to do it? I'm guessing one could restore their phone to factory settings or something.

• Scaffolding Extensions: NoMethodError

  - by marienbad

  Not sure if many people are familiar with Scaffolding Extensions for Ruby, but I've looked through their docs, forums, and even the source code of the Heroku test site, and not found an answer. I made a basic Sinatra app and followed right from the RDoc's instructions: require 'scaffolding_extensions' require 'sinatra/base' class Thingy < Sinatra::Base scaffold_all_models end gives undefined method 'scaffold_all_models' for Thingy:Class (NoMethodError) and I know Scaffolding Extensions is loadable because I can successfully set some config variables in its classes.
