  • Hashtable/Dictionary but with key composed of multiple values?

    - by MC
    Lets say I have an object that has stringProp1, stringProp2. I wish to store each combination of stringProp1, stringProp2 in a Dictionary. Initially I was storing the key as key = stringProp1+stringProp2 but this can actually cause a bug depending on the 2 values. Is the best solution for this problem to create a custom dictionary class or is there a better way using built-in .NET classes?

  • Mixing JQuery Ajax with ASP.NET : is there any security risk

    - by Sayem Ahmed
    I am using jQuery with ASP.NET in a project. Instead of using ASP.NET Ajax, I am using jquery's ajax functions. Is there any security risk if I do that? I mean, since I am using jquery's ajax calls, no view state information will be passed to the server so that it can verify the page's authenticity (though it saves a lot of bandwidth..). I would also like to know what is the best/good practice here.

  • Are there any simple languages implemented using ANTLR or similar?

    - by etheros
    I'm trying to build a simple interpreted language for learning purposes. I've read countless theory and tutorials on ANTLR and JavaCC, but I can't figure out how to actually make it do something useful. I learn best by "taking something apart and putting it back together again", so, are there any working examples of simple languages implemented with the help of tools such as ANTLR, or similar? Something like the following might be nice: x = 1 if x == 1 print "true"

  • Identifying and removing null characters in UNIX

    - by fahdshariff
    I have a text file containing unwanted null characters. When I try to view it in I see ^@ symbols, interleaved in normal text. How can I: a) Identify which lines in the file contains null characters? I have tried grepping for \0 and \x0, but this did not work. b) Remove the null characters? Running strings on the file cleaned it up, but I'm just wondering if this is the best way? Thanks

  • Spawning worker threads

    - by LB
    In C#, How would one go about spawning multiple threads and then sequentially adding results to a list before returning the entire result set? What are some best practices? I'm so far using an ManualResetEvent to signal when the last element has been processed by a thread. But when it returns, I need to have them consolidate the result sets in sequential order so that we don't get into contention issues with the return value list (total results).

  • Windows Service WebBrowser DocumentCompleted Bug

    - by Sam Youtsey
    I've been building a Windows Service to create a WebBrowser object to navigate, login, and download a site's HTML. However, I recently discovered this bug which prevents the DocumentCompleted event from firing if the WebBrowser is not visible: http://support.microsoft.com/kb/259935 I've got to assume this is because the Windows Service doesn't allow for a GUI and therefore this bug is tripped. What is the best workaround for this? Thanks for your help.

Basically i thought of a class from which all other services can inherit, that automatically overrides the default method implementations and wraps them in a logger function. What's the best way to achieve this?

    I'm wanting to order Wordpress posts by the most recent comment. To the best of my knowledge this isn't possible using the WP_Query object, and would require a custom $wpdb query, which I can easily write. However, I then don't know how to setup the loop to run off this object. Can anyone help?
