• Clipping users cursor around the X button.

  - by Nowayz

  This should be simple, and I was hoping to do it in Delphi. The purpose of this is just supposed to be a joke. On a windows form application I don't want the user to be able to clip the X button on the main form. I want the cursor to either clip around the X button or just set it's position elsewhere.

• RTS AI: where to start?

  - by awegawef

  I'd like to begin tinkering around with an RTS AI, but I'm having trouble finding a good environment to work with, ie a game that has been already created. I have looked at Spring RTS and Bos Wars, but they don't seem to be conducive to creating simple examples. I am not totally opposed to writing my own game environment, it would just take a long time. Does anyone have a suggestion as to how I can get my feet wet without programming my own game?

• JPQL (JPA) search substring

  - by JavaBeginner

  Hi, Im facing simple problem with searching entities by some (sub)string, which they might contain. E.g. I have users user1, usr2, useeeer3, user4 and I will enter to search window "use" and I expect to return user1, useeer3, user4. Im sure you know what I mean now. Is there any construction in JPA (JQPL)? It would be nice to search using WHERE somehow in named queries. Something like "SELECT u FROM User u WHERE u.nickname contains :substring"

• How can a not null constraint be dropped?

  - by Tomislav Nakic-Alfirevic

  Let's say there's a table created as follows: create table testTable ( colA int not null ) How would you drop the not null constraint? I'm looking for something along the lines of ALTER TABLE testTable ALTER COLUMN colA DROP NOT NULL; which is what it would look like if I used PostgreSQL. To my amazement, as far as I've been able to find, the MySQL docs, Google and yes, even Stackoverflow (in spite of dozens or hundreds of NULL-related questions) don't seem to lead towards a single simple SQL statement which will do the job.

• Rotate webpage via code?

  - by Adam Davis

  I'm hoping that there's a relatively simple way to rotate a webpage a little bit, 30 degrees or so, while still leaving it fully functional and usable. I completely control the page, and can modify it to make this easier if needed. I'd rather not re-write the whole thing in SVG, though, but perhaps javascript and canvas will work? Is there a way using CSS, Javascript, or some other cross browser method that would allow me to accomplish this?

• XCode code generation

  - by Ali Shafai

  I was wondering if there is a tool (automator script or a third party) to generate code for simple scenarios like add another property. I don't like going to two or three places and write the same thing over and over again. instead I want to say "I want a new property of type int with name X" and it generates the lines in .h and .m files for me in one go.

• Does Chrome always adds an XLS extension on a vnd.ms-excel mime type?

  - by Claudio

  It seems that a simple download of a PHP generated CSV file (with a vnd.ms-excel mime type for the sake of opening it with (Open)Office readly upon the "Save as..." dialog, when present) always gets the unwanted .xls extension when the UA is Google Chrome. The file would then be named as myfile.csv.xls. Firefox behaves correctly. I wonder if it is a bug, a feature or a misunderstanding of some references. Thank you.

• How can I send out diff's of submitted changes to the entire project whenever someone commits a chan

  - by Alex

  I'd like to be able to send all the contributors working on a project a message whenever a commit is made. This way, everyone sees the contribution, and hopefully someone will take a look and spot bugs and whatnot. Furthermore, it provides our bosses with a nice and simple, if a little incomprehensible, way to get an idea of how the project is progressing. We're using Mercurial right now.

• Add querystring parameters to link_to

  - by Craig

  I'm having difficultly adding querystring parameters to link_to UrlHelper. I have an Index view, for example, that has UI elements for sorting, filtering, and pagination (via will_paginate). The will_paginate plugin manages the intra-page persistence of querystring parameters correctly. Is there an automatic mechanism to add the querystring parameters to a give named route, or do I need to do so manually? A great deal of research on this seemingly simple construct has left me clueless.
