• Why won't anyone accept public fields in C#?

  - by Dmitri Nesteruk

  Seems like every C# static analyzer wants to complain when it sees a public field. But why? Surely there are cases where a public (or internal) field is enough, and there is no point in having a property with its get_ and set_ methods? What if I know for sure that I won't be redefining the field or adding to it (side effects are bad, right?) - shouldn't a simple field suffice?

• Android (Milestone/Droid): View.OnKeyListener not working correctly?

  - by Ice09

  I am using a simple EditText and register an View.OnKeyListener. Some GUI changes should happen (fading in/out of views) when certain conditions for the EditView text apply. In the emulator, this works as expected. On the Motorola Droid/Milestone, the listener does not work, only after pressing DEL, the listener is called the first time and always afterwards when activating the number input, the listener works correctly Note: I deactivated the suggestions with TYPE_TEXT_FLAG_NO_SUGGESTIONS and used the IME action IME_ACTION_GO to have a workaround for this (otherwise the user could not "start" a request).

• highlight parent window text when spell checking from child window

  - by Bo Gusman

  I'm working on a simple spell checking app for a lecture that I'm giving. I've got the basic spell checking code working just fine using a child form and NHunspell - great lib, by the way. However, I'd like for the parent textbox to show the highlighted text for reference, and while I'm setting the SelectedText properties accordingly, the text is not highlighted in the parent. Canceling the child window and the parent text is highlighted. Anybody know how I can do this?

• Adding Google Map to Contact Info Page in Drupal

  - by clang1234

  I'm trying to display a Google Map inside a drupal page. The map will only have the business location marker on it, with no need for a user to submitted their own markers. So far I've loaded the Gmap, Location, and CCK modules. I've attempted to enable a location field for Page content types, which allows me to input an address, but this doesn't display the actual map. I'm sure I'm missing something simple here. Any help?

• groovyx.net.ws.WSClient is having problems with ''soapenc:Array' Any workaround?

  - by ?????

  I'm trying to call a webservice (implemented with a .NET/ASP system) from groovy/grails using WSClient. I have no trouble accessing this service using the SOAPClient debugger (Todd Ditchendorf's program for OSX), but when i try it via groovy/grails, I get the error undefined simple or complex type 'soapenc:Array' Is there any solution? Looking at it with wireshark: It seems to have thrown this error even before it gets a chance to perform the transaction. The error is thrown right after WSClient has downloaded the second of two schemas referenced in he WSDL.

• Rsync: pure Ruby implementation?

  - by peter

  I have a Rsync program Deltacopy with an executable as client and server but would like to replace this if possible with a pure Ruby implementation of Rsync. I found gems like six-rsync and rsync-update but they seem to be no general implementations. I'm looking for a pure Ruby solution, so no executables involved and preferably runnable on multiple OS. If possible a simple sample would be great. I only look for Rsync, no other transfer or backup solutions please.

• Page expiration after postback in ASP.NET

  - by Achilles

  I've been doing web development for a while and have yet to read a good answer to this question: Given a page that executes transactions through a postback, how do you prevent the user from duplicating the transaction when they do something as simple as hit the back button? I've explored trying expire the cache but I must admit I'm lacking in my understanding of ASP.NET caching. What is the approach I should use to make the old request stale and invalid? Thanks!

• Is there a floating point value of x, for which x-x == 0 is false?

  - by Andrew Walker

  In most cases, I understand that a floating point comparison test should be implemented using over a range of values (abs(x-y) < epsilon), but does self subtraction imply that the result will be zero? // can the assertion be triggered? float x = //?; assert( x-x == 0 ) My guess is that nan/inf might be special cases, but I'm more interested in what happens for simple values.

• java double[][] - display as image

  - by joe_shmoe

  Hi all, just wondering if there is a simple way in java to display the contents of say 16x16 array of doubles [0..1] as a greyscale image (ala matlab)? using an unfamiliar matrix library, so I'd like to check that I'm on the right track. don't really care if it is slow or ugly, or if it requires external library - it's just there for a quick look, so as long as it works, I'm fine.
