  • New to threading in C#, can you make thread methods generic and what are the dangers?

    - by ibarczewski
    Hey all, I'm just now starting to get into the idea of threading, and wanted to know if I could make this more abstract. Both foo and bar derive methods from a base class, so I'd like to pass in one or the other and be able to do work using a method that was derived. I'd also like to know how you properly name threads and the methods inside threads. if (ChkFoo.Checked) { Thread fooThread = new Thread(new ThreadStart(this.ThreadedFooMethod)); fooThread.Start(); } if (ChkBar.Checked) { Thread barThread = new Thread(new ThreadStart(this.ThreadedBarMethod)); barThread.Start(); } . . . public void ThreadedFooMethod() { Foo newFoo = new Foo(); //Do work on newFoo } public void ThreadedBarMethod() { Bar newBar = new Bar(); //Do similar work } Thanks all!

  • Using JQuery Lightbox within AJAX loaded content

    - by James
    Hey. So this is probably a very noob problem but I'm not good enough to fix it. Basically... I have a gallery that I am loading into the page via AJAX. It looks simply like this: <div id="gallery"> <a href="Image1.jpg"><img src="Image1Thumb.jpg" /></a> <a href="Image2.jpg" title=""><img src="Image2Thumb.jpg" /></a> </div> But because it's being loaded in as AJAX content, JQuery/Lightbox is not working and I've no idea how can I get the script to run/recognise this newly loaded content. Thanks! [Note: The JQuery Lightbox I am using.]

  • WordPress [img] tags

    - by Lokheed
    Hey guys, I'm trying to allow that standard BB [img] [/img] tags on my WordPress blog. I got this snippet from the net, but it only works on lower case [img] tags. I'd like it to apply to both [img] and [IMG]. As you can tell, I'm totally not a coder. function embed_images($content) { $content = preg_replace('/\[img=?\]*(.*?)(\[\/img)?\]/e', '"<img src=\"$1\" alt=\"" . basename("$1") . "\" />"', $content); return $content; } add_filter('comment_text', 'embed_images'); I know '||' is 'or' but don't know enough coding to make the changes. Any help is greatly appreciated. Thanks.

  • C++ LoadLibrary() from the current path

    - by gillyb
    Hey, I'm a .net developer mostly, doing something small in C++ so im having a little trouble. I'm loading another C++ dll using hInst = LoadLibrary(TEXT("mydll.dll")); and I came to realize that this looks for the dll I'm trying to load in 'C:\' or in 'system32'. Can someone show me how to load the dll from the current directory (without knowing what the current directory is ahead of time) ?? I know I should be using something like GetFullPathName but I'm having a little trouble getting it to work on my own...

  • how to find which libraries to link to? or, how can I create *-config (such as sdl-config, llvm-con

    - by numeric
    Hey, I want to write a program that outputs a list of libraries that I should link to given source code (or object) files (for C or C++ programs). In *nix, there are useful tools such as sdl-config and llvm-config. But, I want my program to work on Windows, too. Usage: get-library-names -l /path/to/lib a.cpp b.cpp c.cpp d.obj Then, get-library-names would get a list of function names that are invoked from a.cpp, b.cpp, c.cpp, and d.obj. And, it'll search all library files in /path/to/lib directory and list libraries that are needed to link properly. Is there such tool already written? Is it not trivial to write a such tool? How do you find what libraries you should link to? Thanks.

  • JSF 2 Content Controller (pull in content based on URI)

    - by gerges
    Hey All, I'm new to JSF and am trying to make a content controller. Basically whenever someone makes a request to www.myapp.com/external/** I'd like to forward to a controller that pulls external content into a page template and spits it out to the user. I was able to achive this pretty easily in Spring 3, but I'm a little confused on where to start with JSF. I feel like I'd need to create a custom servlet to handle /external/**? But what would the class of this servlet be? What would it consist of? Any help is appreciated!

  • How to properly design a simple favorites and blocked table?

    - by Nils Riedemann
    Hey, i am currently writing a webapp in rails where users can mark items as favorites and also block them. I came up two ways and wondered which one is more common/better way. 1. Separate join tables Would it be wise to have 2 tables for this? Like: users_favorites - user_id - item_id users_blocked - user_id - item_id 2. single table users_marks (or so) - users_id - item_id - type (["fav", "blk"]) Both ways seem to have advantages. Which one would you use and why?

  • Keyup attribute 'name' change not working

    - by dclowd9901
    Hey guys, I've got what I imagine is a simple question, but for some reason, I can't get it working right. Expected Behavior: I type characters into a field, and, through a function, those characters are translated into the value of the name HTML attribute. Actual Behavior: Reflected in Firebug, the value doesn't change or update. The Code: $('input').live('keyup', function() { var name_value = $(this).val().toLowerCase(); $(this).attr('name', name_value); }); Just a side note: I'm using .live() because the element can be cloned, and those clones need to also be able to take on the properties of this .keyup event. Any ideas?

  • Check if exists, if so, update by 1++, if not insert

    - by Scarface
    Hey guys quick question, I currently have an insert statement $query= "INSERT into new_mail VALUES ('$to1', '0')"; where fields are username, and message_number Currently what I would do to check if the entry exists, is do a select query then check the number of rows with mysql_num_rows (php). If rows==1 then I get the current message_number and set it equal to $row['message_number']++1. Then I update that entry with another query. Is there an easier way to do all this in just mysql with just one query (check if exists, if not insert, if so update message_number, increase by 1)?

  • Can anyone help me with a complex sum, 3 table join mysql query?

    - by Scarface
    Hey guys I have a query and it works fine, but I want to add another table to the mix. The invite table I want to add has two fields: username and user_invite. Much like this site, I am using a point system to encourage diligent users. The current query which is displayed below adds the up votes and down votes based on the user in question: $creator. I want to count the number of entries for that same user from the invite table, and add 50 for each row it finds to the current output/sum of my query. Is this possible with one query, or do I need two? "SELECT *, SUM(IF(points_id = \"1\", 1,0))-SUM(IF(points_id = \"2\", 1,0)) AS 'total' FROM points LEFT JOIN post ON post.post_id=points.points_id WHERE post.creator='$creator'"

  • Absolute URL Generation with Subdirectory in Rails

    - by Hulihan Applications
    Hey Guys - I'm trying to find an easy way(without having to write any plugins or overrides to Rails) to generate an absolute url to a rails application being in a subdirectory. This url is going to be generated for theme images, not links, so I can't url link_to or url_for. Here's an example of what I want to do: <%= theme_image("delete_icon.png", :theme => "my_theme") %> If my app is running at http://localhost, This would return: <img src="/themes/my_theme/images/delete_icon.png"> but If my app is running at http://localhost/myapp, This would return: <img src="/myapp/themes/my_theme/images/delete_icon.png"> Can anyone point me in the right direction to generate a dynamic, absolute url to a non-routed resource?

  • Copying Primary key to another field in Access.

    - by BashLover
    Hey, I'm struggling to copy the Primary Key to another field in Access. This is irrelevant , but clarifying on what I'm comparing. ... WHERE Tunniste=" & [Tarkiste] & "" Tunniste = Primary Key , Autonumber , ID (Generated by Access.) Tarkiste = This is the field I want to copy it to compare it. I'm open to suggestions, I've already try'ed with Form_Load, using the following code. Private Sub Form_Load() DoCmd.RunSQL "UPDATE Korut SET [Tarkiste]=('" & Tunniste & "');" End Sub But this copied the same key to all the entries in "Tarkiste" field. In simplicity I want 1:1 copy of field "Tunniste" to "Tarkiste" , whichever method it takes. Started from this question. File Picker Replaces All Rows With The Same Choice.

  • [.net] Treeview prevent Node collapse (weird problem)

    - by cssnoob
    Hey guyz! I have a .net 2.0 C# Project. I have a Treeview with 2 Nodes, each of them has many child nodes. When you click on a child node, a PDF is displayed in a webbrowser control depending on the properties of the node. Fine, but the problem is that when both Nodes are expanded, and I click on a child node, the other node gets collapsed! I don't have any code that collapses any node of the treeview, but somehow it happens! I also had a look at the BeforeCollapse Event, but somehow it doesn't fire, alltough the other node collapses! Can anyone imagine why this happens? I would be very grateful if anyone can teach me how to prevent this happening! Thank you very much!

  • Android: how to start a service at boot based on user-settings?

    - by Cicerone Cojocaru
    Hey everyone, I'm trying to write an app that consists of an activity that manages a background service. However, I want to implement a user setting for automatically starting the service up at boot time. I have user settings implemented with SharedPreferences and I have the services starting up at boot by using a BroadcastReceiver and listening for BOOT_COMPLETED. However, I can't figure out a good way to implement a setting so that the service is only started at boot if said setting is enabled. I can think of a few cheap ways to do this (such as messing with onCreate() in the service, or creating/checking for a file on SD card) but I want to follow good practice. There must be a good way to do this because there's tons of apps out there that do it, I just can't find anything online about how to do it. Thanks

  • SetWindowLongPtr with DialogBoxParam?

    - by templatetypedef
    Hey all- A while back I was writing a C++ program with the Win32 API that would display a dialog box and then listen to the messages it generated. At one point, I was interested in associating a piece of data with the dialog window. Were I manually creating the window and attaching a window proc, I'd just use SetWindowLongPtr to set the GWLP_USERDATA field to a pointer to the data to associate. However, in this case I was creating and displaying the window with DialogBoxParam, and it wasn't clear whether this function was associating that data with its own internal state. Since the MSDN didn't have a description of what would happen in this case, I ended up using some other approach to solve the problem. My question is this - is it safe to use SetWindowLongPtr to overwrite the GWLP_USERDATA value in a window created by DialogBoxParam? Thanks!

What I would like it to do is have anybody comment on it (they don't need to login). The comment submission form just required a Name and comment. What would be the simplest way to do this? It would also be nice to have it display how many comments there currently are on the news post. I dont need anything fancy. Thanks!
