  • crosshair tool, is there one? Visual studio 2008

    - by flavour404
    Hi, I am doing some image sampling. What my question is, is there a 'crosshair' tool in visual studio? I want to have several instances on a single form, be able to move them around and then sample those points, obviously returning the color of the pixel at the center of the crosshair, is there already a tool that will do this, before I go and write one? Thanks, R.

  • Java, user input to the command line when using Runtime.getRuntime().exec(command);

    - by user1557354
    I dont think this is possible, but I have been using: Process p = Runtime.getRuntime().exec(command); to run commands on the command line, but now I have come accross a situation where the command I am running part way through will ask for some user input, for example a username. This can not be resolved by a argument to the command that is being exec, is there any way I can pass the username to the same command line instance and continue? Thanks in advance.

  • check all values match using prototype

    - by snaken
    Using prototype, is there a simple method of checking that a group of values match, for example - can this code be refined to a single line or something otherwise more elegant? var val = ''; var fail = false; $('form').select('.class').each(function(e){ if(!val){ val = $F(e); }else{ if(val != $F(e)) fail = true; } });

  • Methods in Ruby: objects or not?

    - by Mladen Jablanovic
    Inspired by this discussion, after some googling I wasn't able to find an answer to a pretty simple question regarding methods in Ruby: are they objects or not? There are different opinions here and there, and I would really like to hear, let's say, an in-depth explanation. I'm aware of Object#method method, which takes a method name and returns a Method instance, but, on the other hand, there's a similar thing you can do with blocks to make them into Proc instances, and blocks aren't objects, so what makes methods any different?

  • Activerecord default accessors & unusual requirements

    - by JP
    I have an ActiveRecord::Base class which needs to have a field that is automatically generated when a new instance is made. How should I go about doing this? By defining an initialize function? class Thing < ActiveRecord::Base # 'special' (integer) needs to be set to lowest unused number (above 0) # considering that random rows will be removed via other processes end This is as far as I've got! Any ideas?

  • Using mod_negotiation to serve webp if the UA requests it.

    - by Rich Bradshaw
    Is it possible to use mod_negotiation to serve up a webp image if the browser supports it, and a jpg otherwise? For instance, if I link to an image with the path /images/test, it serves the image found at /images/test.webp if the UA knows about webp, or jpg otherwise? I've tried poking around, but it seems that the Accept headers in Chrome at least look like Accept:*/*, rather than specifying the image type. If this isn't the way to do it, has anyone got any other suggestions?

    - by bito08
    Hello after doing the parsing with a script in Haskell I got a file with the 'appearance' of lists of strings. However when I call the file content with the function getContents or hGetContents, ie, reading the contents I get something like: String with lines (schematically what I want is: "[" aaa "," bbb "" ccc "]" - ["aaa", "bbb" "ccc"]). I have tried with the read function but without results. I need to work with these lists of strings to concatenating them all in a single list. Thanks.

  • Internal classes with ADO.NET Entity Framework

    - by Regent
    I'm using Entity Framework for creation of my Data Access Layer and I want for all of my classes to be internal. I know it is possible to manually assign it manually in the designer for each class. But looks like it also requires to set internal modifier for each single property in every class! I have about 30+ entities and it will be a huge work to do. Do you know any ideas how to set a 'default access' for the entire model?

For instance, having the widget move only in one axis, or have the widget move double the distance between the cursor and the drag starting point. Which method should I override to define this kind of behaviour?
