  • Using AJAX to POST data to PHP database, then refresh

    - by cb74656
    Currently I have a button: <ul> <li><button onclick="display('1')">1</button></li> <li><button onclick="display('2')">2</button></li> <li><button onclick="display('3')">3</button></li> </ul> That when pressed, calls a javascript function, and displays PHP based on which button is pressed using AJAX. I figured this out all on my own. The AJAX gets a PHP file with a postgres query that outputs a table of data to a div. Now I want to be able to add, via form, new data and have it refresh (without reloading the page, yannknow?). I've tried a couple of things, and have hit roadblocks every time. My initial idea was to have the form submit the data using a javascript function and AJAX, then call my "display()" function after the query to reload the content. I just can't figure it out using GoogleFu. Based on my current idea, I'd like help with the following: How do I pass the form data to a javascript function. How do I use POST to pass that data to PHP using AJAX? I'm super new to javascript and AJAX. I've looked into jquery as it seems like that's the way to go, but I can't figure it out. If there's a better way to do this, I'm open to suggestions. Please forgive any misuse of nomenclature. EDIT: Once I solve this problem..., I'll have all the tools needed to finish the project preliminarily.

  • CakePHP - recursive on specific fields in model?

    - by Paul
    Hi, I'm pretty new to CakePHP but I think I'm starting to get the hang of it. I'm trying to pull related table information recursively, but I want to specify which related models to recurse on. Let me give you an example to demonstrate my goal: I have a model "Customer", which has info like Company name, website, etc. "Customer" hasMany "Addresses", which contain info for individual contacts like Contact Name, Street, City, State, Country, etc. "Customer" also belongsTo "CustomerType", which is just has descriptive category info - a name and description, like "Distributor" or "Manufacturer". When I do a find on "Customer" I want to get associated "CustomerType" and "Address" info as sub-arrays, and this works fine just by setting up the hasMany and belongsTo associations properly. But now, here's my issue: I want to get associated State/Country info. So, instead of each "Address" array row just having "state_id", I want it to have "state" = array("id" = 20, "name" = "New York",...) etc. If I set $recursive to a higher value (e.g., 2) in the Partner model, I get what I want for the State/Country info in each "Address". BUT it also recurses on "CustomerType", and that results in the "CustomerType" field of my "Partner" object having a huge array of all Customer objects that match that type, which could be thousands long. So the point is, I DON'T want to recurse on "CustomerType", only on "Address". Is there a way I can set this up? Sorry for the long-winded question, and thanks in advance!

  • Loading a UIView from a UITableview

    - by Michael Robinson
    I can firgure out how to push a UIView from a Tableview and have the "child" details appear. Here is the view I'm trying to load: Here is the code that checks for children and either pushes a itemDetail.xib or an additional UITable, I want to use the above .xib but load the correct contents "tableDataSource" into the UItable: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //Get the dictionary of the selected data source. NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; //Get the children of the present item. NSArray *Children = [dictionary objectForKey:@"Children"]; if([Children count] == 0) { ItemDetailViewController *dvController = [[ItemDetailViewController alloc] initWithNibName:@"ItemDetailView" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:dvController animated:YES]; [dvController release]; } else { //Prepare to tableview. FirstTab *rvController = [[FirstTab alloc] initWithNibName:@"FirstView" bundle:[NSBundle mainBundle]]; //Increment the Current View rvController.CurrentLevel += 1; //Set the title; rvController.CurrentTitle = [dictionary objectForKey:@"Title"]; //Push the new table view on the stack [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController release]; } } Thanks for the help. I see lots of stuff on this but can't find the correct push instructions.

  • sql query selecting one name no matter how many rows it was mentioned in

    - by Baruch
    Basically what I'm trying to do is get the information from column x no matter how many times it was mentioned. means that if I have this kind of table: x | y | z ------+-------+-------- hello | one | bye hello | two | goodbye hi | three | see you so what I'm trying to do is create a query that would get all of the names that are mentions in the x column without duplicates and put it into a select list. my goal is that I would have a select list with TWO not THREE options, hello and hi this is what I have so far which isn't working. hope you guys know the answer to that: function getList(){ $options="<select id='names' style='margin-right:40px;'>"; $c_id = $_SESSION['id']; $sql="SELECT * FROM names"; $result=mysql_query($sql); $options.="<option value='blank'>-- Select something --</option>" ; while ($row=mysql_fetch_array($result)) { $name=$row["x"]; $options.="<option value='$name'>$name</option>"; } $options.= "</SELECT>"; return "$options"; } Sorry for confusing... i edited my source

  • How do I stop events from bubbling/multiple events with animated mouseovers?

    - by Kurucu
    I noticed a lot of JQuery answers on this, but I'm using MooTools... I have a Table of Contents which uses CSS Fixed positioning to keep it off to the left side, except for 20 pixels. The user hovers their cursor over the 20 pixels, which fires the DIV's mouseover event and the ToC slides fully into the page. When the cursor leaves, the ToC slides back to where it was. $('frameworkBreakdown').addEvents({ 'mouseover': function(event){ event = new Event(event); $('frameworkBreakdown').tween('left', 20); event.stop; }, 'mouseout': function(event){ event = new Event(event); $('frameworkBreakdown').tween('left', (10 - $('frameworkBreakdown').getStyle('width').toInt()) ); event.stop; } }); This works well (aside from unrelated issues) except that when I move the mouse on the DIV it starts to jitter, presumably because the contents of the DIV are also firing the event, or the event refires as the mouse tracks over the DIV. How can I stop this behaviour from occuring? Is there a standard method, or do I use some sort of nast global variable that determines whether effects are in action, and thus ignore the event?

  • CSS: Parent-Div does not grow with it's children (horizontal)

    - by vyden_st
    I would like the parent-div (red) to grow with the green child-div. Now it just stops at the viewport. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html lang="de" xmlns="http://www.w3.org/1999/xhtml" xml:lang="de"> <head> <title>simple document</title> <style type="text/css"> * { font-family: verdana; margin: 0px; padding: 0px; } </style> </head> <body> <div style="margin: 30px; background: red; padding: 10px;"> <div style="background: green; width: 2000px;">dxyf</div> </div> </body> </html> I don't want to use display:table; since it does not work well in IE. Any ideas?

  • Require reasonably random results from an SQL SELECT query within a Joomla article (Cache enabled)

    - by Shrinivas
    Setup: Joomla website on LAMP stack I have a MySQL table containing some records, these are queried by a simple SELECT on the Joomla article, as pasted below. This specific Joomla website has Caching turned on in Joomla's Global Configuration. I need to randomize the order in which I display the resultset, each time the page is loaded. Regular php/mysql would offer me two approaches for this: 1. use 'order by RAND()' or any of a number of methods to allow a SELECT query to return reasonably random results. 2. once php gets the result from the SELECT into an array, shuffle the array to get a reasonably random order of array items. However, as this Joomla instance has Caching turned ON in its Global Configuration, either of the above approaches fails. The first time I load the page the order is randomized, however any further reloads do not cause the order to change, as the page is delivered from cache. The instant the Cache is disabled, both approaches (shuffle/order by rand) work perfectly. What am I missing? How do I override the Global Cache for this specific article? A very simple requirement, that is met by both php and mysql reasonably well, is blocked by the Joomla Cache that I cannot turn off. The php that returns results from the database. <pre> $db = JFactory::getDBO(); $select = "SELECT id FROM jos_mytable;"; //order by RAND() $db->setQuery($select); echo $db->getQuery(); //Show me the Query! $rows = $db->loadObjectList(); //shuffle($rows); foreach($rows as $row) { echo "$row->id"; }

  • Is there a maximum number of input controls that can be used on an HTML form?

    - by Rich
    I have an ambitious requirement for an asp.net 2.0 web page that contains a table (gridview), and each row in the grid contains 6 select (dropdown) controls for data entry. The number of rows that will be displayed is dependent upon the user's search parameters, which are specified in another area of the page. Unfortunately, with the default (and even basic) search parameters specified, the grid could contain several hundred rows. I've noticed that the browser, in this case IE8, starts behaving rather erratically once I reach a large number of rows -- no documented evidence for the number of rows where this begins to be a problem. For example, trying to view the source of the page results in a message from IE stating that there was a problem with the page that forced the browser to reload it, and I never get the source. Obviously the page loads and renders rather slowly also. I know that my solution is probably going to involve paging the gridview such that it only displays 20 or so rows per page, and I'll have to write code to handle the saving of changes in the dropdown values when the user changes pages. I can probably turn off viewstate on the gridview also. However, the question I really want to pose is this -- has anyone seen a documented rule indicating the maximum number of input controls that an HTML browser form is supposed to be able to contain? I could not find anything on the Internet after doing a search, and I suspect the answer may be whatever the browser can handle based on the machine configuration it is running on. Any rules of thumb you use? Thanks for any suggestions. Rich

  • CSS to Make 2 Column Content Areas

    - by Joe Majewski
    I'm trying to stray away from using tables to form the layout of my content, and I can think of two alternatives that I'd like to better learn: (1) styling list items to be side-by-side, and (2) using div blocks that float onto the same line. Both of these would have their own uses for what I'm working on. I'm already using div tags to form the entire layout of my three-column template, but what I need to do now is a bit different. In case it helps, my project can be found here. In short, here's my question; how would I style a div so that the width of it is 50% of the width of the area it occupies, rather than 50% of the width of the page? As for my other question, what would be the best approach to styling list items so that they are side-by-side? I'm working on a registration script now, and instead of using a table with "Username" on the left and the input text on the right, I can use two list items. It's late and I've been working on this project of mine for about 8 hours straight now, so I apologize if I'm asking anything confusing. Feel free to ask me any questions about what I'm trying to do. Thanks, friends. :)

  • Formating a date field in the Model (Codeigniter)

    - by Landitus
    Hi, I', trying to re-format a date from a table in Codeigniter. The Controller is for a blog. I was succesfull when the date conversion happens in the View. I was hoping to convert the date in the Model to have things in order. This is the Model: class Novedades_model extends Model { function getAll() { $this->db->order_by('date','desc'); $query = $this->db->get('novedades'); if($query->num_rows() > 0) { foreach ($query->result() as $row) { $data[] = $row; } } return $data; } } This is part of the controller $this->load->model('novedades_model'); $data['records'] = $this->novedades_model->getAll(); Here's the date conversion as it happens in the View. This is inside the posts loop: <?php foreach($records as $row) : ?> <?php $fdate = "%d <abbr>%M</abbr> %Y"; $dateConv = mdate($fdate, mysql_to_unix($row->date)); ?> <div class="article section"> <span class="date"><?php echo $dateConv ;?></span> ... Keeps going ... How can I convert the date in the Model? Can I access the date key and refactor it?

  • Displaying count for current_user 'likes' on a 'question' in questions/show.html.erb view

    - by bgadoci
    I have an application that allows for users to create questions, create answers to questions, and 'like' answers of others. When a current_user lands on the /views/questions/show.html.erb page I am trying to display the total 'likes' for all answers on that question, for the current_user. In my Likes table I am collecting the question_id, site_id and the user_id and I have the appropriate associations set up between user, question, answers and likes. I think I just need to call this information the right way, which I can't seem to figure out. All of the below is taking place in the /views/questions/show.html.erb page. I have tried the following: <% div_for current_user do %> You have liked this question <%= @question.likes.count %> times <% end %> Which returns all the 'likes' for the question but not filtered by current_user You have liked this question <%= current_user.question.likes.count %> times Which gives an error of 'undefined method `question' You have liked this question <%= @question.current_user.likes.count %> times Which gives an error of 'undefined method `current_user' I have tried a couple of other things but they don't make as much sense as the above to me. What am I missing?

  • PHP the SELECT FROM WHERE col IN no working using array

  • While in a transaction, how can reads to an affected row be prevented until the transaction is done?

    - by Mahn
    I'm fairly sure this has a simple solution, but I haven't been able to find it so far. Provided an InnoDB MySQL database with the isolation level set to SERIALIZABLE, and given the following operation: BEGIN WORK; SELECT * FROM users WHERE userID=1; UPDATE users SET credits=100 WHERE userID=1; COMMIT; I would like to make sure that as soon as the select inside the transaction is issued, the row corresponding to userID=1 is locked for reads until the transaction is done. As it stands now, UPDATEs to this row will wait for the transaction to be finished if it is in process, but SELECTs simply will read the previous value. I understand this is the expected behaviour in this case, but I wonder if there is a way to lock the row in such a way that SELECTs will also wait until the transaction is finished to return the values? The reason I'm looking for that is that at some point, and with enough concurrent users, it could happen that while the previous transaction is in process someone else reads the "credits" to calculate something else. Ideally the code run by that someone else should wait for the transaction to finish to use the new value, because otherwise it could lead to irreversible desync issues. Note that I don't want to lock the entire table for reads, just the specific row. Also, I could add a boolean "locked" field to the tables and set it to 1 every time I'm starting a transaction but I don't really feel this is the most elegant solution here, unless there is absolutely no other way to handle this through mysql directly.

  • How to randomly assign a partner?

    - by David
    I asked a question some time ago about creating a random circular partner assignment using php and mysql. This is a related issue. I am working from the following code to try to give two users new, randomly selected partners: $q = "SELECT user_id FROM users WHERE partner='$quit_partner' AND status='1'"; $r = mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc)); while ($row = mysqli_fetch_array($r)) { $users[] = $row[0]; } $current = end($users); $partners = array(); foreach ($users as $user) { $partners[$user] = $current; $current = $user; $q = "UPDATE users SET partner='{$partners[$user]}' WHERE user_id='{$user}'"; mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc)); } Basically, a particular user (lets say user #4) quits the activity, leaving multiple other users without a partner (hypothetically, users # 5,6,7). I need to find out who those users are, hence the first query. Once I find them, I throw them into an array. Then comes the difficult part. I want those newly partnerless users (5,6,7) to be randomly assigned new partners from everyone in the table. The current code is flawed in that it only assigns the newly partnerless users eachother. Thanks for your help.

  • jquery pagination plugin doesn't quite work right for me...

    - by Pandiya Chendur

Any suggestion how to get this done.......

  • MS SQL - High performance data inserting with stored procedures

    - by Marks
    Hi. Im searching for a very high performant possibility to insert data into a MS SQL database. The data is a (relatively big) construct of objects with relations. For security reasons i want to use stored procedures instead of direct table access. Lets say i have a structure like this: Document MetaData User Device Content ContentItem[0] SubItem[0] SubItem[1] SubItem[2] ContentItem[1] ... ContentItem[2] ... Right now I think of creating one big query, doing somehting like this (Just pseudo-code): EXEC @DeviceID = CreateDevice ...; EXEC @UserID = CreateUser ...; EXEC @DocID = CreateDocument @DeviceID, @UserID, ...; EXEC @ItemID = CreateItem @DocID, ... EXEC CreateSubItem @ItemID, ... EXEC CreateSubItem @ItemID, ... EXEC CreateSubItem @ItemID, ... ... But is this the best solution for performance? If not, what would be better? Split it into more querys? Give all Data to one big stored procedure to reduce size of query? Any other performance clue? I also thought of giving multiple items to one stored procedure, but i dont think its possible to give a non static amount of items to a stored procedure. Since 'INSERT INTO A VALUES (B,C),(C,D),(E,F) is more performant than 3 single inserts i thought i could get some performance here. Thanks for any hints, Marks

  • Can I get away with this or is it just too crude and unpractical ?

    - by The_AlienCoder
    I spent the whole of last night searching for a free AspNet web chat control that I could simply drag into my website. Well the search was in vain as I could not find a control that matched my needs i.e List of users, 1 to 1 chat, Ability to kick out users.. In the end I decided to create my own control from scractch. Although it works well on my machine Im concerned that It maybe a little crude and unpractical on a shared hosting enviroment. Basically this is what I did : Created an sql database that stores the chat messages. Wrote the stored procedures and and included a statement that clears old messages Then the 'crude' part : Dragged an update panel and timer control on my page Dragged a Repeater databound to the chat messages table inside the update panel Dragged another update panel and inside it put a textbox and a button Configured the timer control to tick every 5 seconds. ..and then I made it all work like this In the timer tick event I 'refreshed' the messages display by invoking Databind() on my repeater i.e protected void Timer1_Tick(object sender, EventArgs e) { MyRepeater.DataBind(); } Then in my send button click event protected void btnSend_Click(object sender, EventArgs e) { MyDataLayer.InsertMessage(Message, Sender, CurrTime); } Well It works well on my machine and Ive got the other functionalities(users list, kick out user..) to work by simply creating more tables. But like I said it seems a little crude to me. so I need a proffesional opinion. Should I run with this or try another Approach ?

  • creating tables in ruby-on-rails 3 through migrations?

  • Query not being executed

    I'm trying to create a script that allows me to upload an image, grab the details sent through inputs (a description and chosen project number) and insert this information into a table. I currently have this function: public function NewEntry() { $connect = new dbconnect; $_SESSION['rnd'] = substr(number_format(time() * rand(),0,'',''),0,15); $allowedExts = array("gif", "jpeg", "jpg", "png"); $size = $_FILES["file"]["size"]; $path = $_FILES["file"]["name"]; $extension = pathinfo($path, PATHINFO_EXTENSION); $pr = $_POST['project']; $cl = $_POST['changelog']; $file = $_SESSION['rnd'] .

The dbconnect class isn't at fault as it's untampered and has been used in past projects. The error logs don't give any output and no MySQL errors show. Any ideas?

  • How can I synchronize one set of data with another?

    - by RenderIn
    I have an old database and a new database. The old records were converted to the new database recently. All our old applications continue to point to the old database, but the new applications point to the new database. Currently the old database is the only one being updated, so throughout the day the new database becomes out of sync. It is acceptable for the new database to be out of sync for a day, so until all our applications are pointed to the new database I just need to write a nightly cron job that will bring it up to date. I do not want to purge the new database and run the complete conversion script each night, as that would reduce uptime and would create a mess in our auditing of that table. I'm thinking about selecting all the data from the old database, converting it to the new database structure in memory, and then checking for the existence of each record before inserting it in the new database. After that's done, I'd select everything from the new database and check if it exists in the old one, and if not delete it. Is this the simplest way to do this?

  • Error in django using Apache & mod_wsgi

    - by Ignacio
    Hey, I've been doing some changes to my django develpment env, as some of you suggested. So far I've managed to configure and run it successfully with postgres. Now I'm trying to run the app using apache2 and mod_wsgi, but I ran into this little problem after I followed the guidelines from the django docs. When I access localhost/myapp/tasks this error raises: Request Method: GET Request URL: http://localhost/myapp/tasks/ Exception Type: TemplateSyntaxError Exception Value: Caught an exception while rendering: argument 1 must be a string or unicode object Original Traceback (most recent call last): File "/usr/local/lib/python2.6/dist-packages/django/template/debug.py", line 71, in render_node result = node.render(context) File "/usr/local/lib/python2.6/dist-packages/django/template/defaulttags.py", line 126, in render len_values = len(values) File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 81, in __len__ self._result_cache = list(self.iterator()) File "/usr/local/lib/python2.6/dist-packages/django/db/models/query.py", line 238, in iterator for row in self.query.results_iter(): File "/usr/local/lib/python2.6/dist-packages/django/db/models/sql/query.py", line 287, in results_iter for rows in self.execute_sql(MULTI): File "/usr/local/lib/python2.6/dist-packages/django/db/models/sql/query.py", line 2369, in execute_sql cursor.execute(sql, params) File "/usr/local/lib/python2.6/dist-packages/django/db/backends/util.py", line 19, in execute return self.cursor.execute(sql, params) TypeError: argument 1 must be a string or unicode object ... ... ...

Don't want to fill this Question with code, so if you need some more info I'd be glad to provide it. Thanks

  • How do I create and populate a non-uniformly structured array in PHP?

    - by stormist
    I am trying to decide on a data structure for an array that has a date for the key and the amount of bandwidth consumed as values. examples Key Consumed Policy October 50 Basic November 75 Basic December 100 Basic Some months, but not all, will have more than one policy. In that case, I need break them down by policy once the total is shown. So for the above example, assume December had 3 policies. The table i construct from my array would then need to show: Key Consumed Policy October 50 Basic November 75 Basic December 100 .. December 25 Basic December 25 Extended December 50 Premium Could all this data be represented in an array ? $myArray['december'] would be a different data structure than the others because it would need a last entry, probably another array, that had the policy names as keys and the amount of data consumed as values. Does PHP allow for arrays that are not structured uniformly? i.e. key october and November have only 2 entries under their key while December has 2 entries plus a 3rd which is an additional array. My best guess is something like: Array ( [October] => "50", "Basic" [November] => "75", "Basic" [December] => "100", "..", Array( [Basic] => 25 [Extended] =>25 [Premium] => 50 ) ) My question is if this is possible and how to declare it and populate it with values with PHP. Thanks in advance for any clarifications or assistance!

  • auto_complete plugin error: Couldn't find Question with ID=auto_complete_for_tag_tag_name

    - by bgadoci
    I have successfully set up this plugin before so I am curious as to what I am doing wrong here. I have built the ability for users to add tags to questions. I am not using tagging plugin here but that shouldn't matter for this. With respect to the auto complete, I am trying to have the form located in the /views/questions/show.html.erb file access the Tags table and display entries in the tags.tags_name column. When I begin to type in the field I get the following error message: Processing QuestionsController#show (for 127.0.0.1 at 2010-05-31 15:22:20) [GET] Parameters: {"tag"=>{"tag_name"=>"a"}, "id"=>"auto_complete_for_tag_tag_name"} Question Load (0.1ms) SELECT * FROM "questions" WHERE ("questions"."id" = 0) ActiveRecord::RecordNotFound (Couldn't find Question with ID=auto_complete_for_tag_tag_name): app/controllers/application_controller.rb:15:in `init_data' For some reason I am actually passing the field name as the Question.id. The plugin set up is fairly simple as you add the following line to your controller: auto_complete_for :tag, :tag_name and the following line in your routes.rb file: map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get } I have added the controller line to both my tags and questions controller and also mapped resources for both tags and questions in my routes.rb file: map.resources :tags, :collection => {:auto_complete_for_tag_tag_name => :get } map.resources :questions, :collection => {:auto_complete_for_tag_tag_name => :get } I have played around with removing either or of the above but can't seem to fix it. Any ideas what I am doing wrong here?

  • when to use Hibernate vs. Simple ResultSets for small application

    - by luke
    I just started working on upgrading a small component in a distributed java application. The main application is a rather complicated applet/servlet combo running on JBoss and it extensively uses Hibernate for its DataAccess. The component i am working on however is very a very straightforward data importing service. Basically the workflow is Listen for a network event Parse the data packet, extract a set of identifiers Map the identifier set to a primary key in our database Parse the rest of the packet and insert items in a related table using the foreign key found in step 3 Repeat in the previous version of this component it used a hibernate based DAL, that is no longer usable for a variety of reasons (in particular it is EOL), so I am in charge of replacing the Data Access layer for this component. So on the one hand I think i should use Hibernate because that's what the rest of the application does, but on the other i think i should just use regular java.sql.* classes because my requirements are really straightforward and aren't expected to change any time soon. So my question is (and i understand it is subjective) at what point do you think that the added complexity of using an ORM tool (in terms of configuration, dependencies...) is worth it? UPDATE due to the way the DataAccesLayer for the main application was written (weird dependencies) i cannot easily use it, i would have to implement it myself.

  • And now for a complete change of direction from C++ function pointers

    - by David
    I am building a part of a simulator. We are building off of a legacy simulator, but going in different direction, incorporating live bits along side of the simulated bits. The piece I am working on has to, effectively route commands from the central controller to the various bits. In the legacy code, there is a const array populated with an enumerated type. A command comes in, it is looked up in the table, then shipped off to a switch statement keyed by the enumerated type. The type enumeration has a choice VALID_BUT_NOT_SIMULATED, which is effectively a no-op from the point of the sim. I need to turn those no-ops into commands to actual other things [new simulated bits| live bits]. The new stuff and the live stuff have different interfaces than the old stuff [which makes me laugh about the shill job that it took to make it all happen, but that is a topic for a different discussion]. I like the array because it is a very apt description of the live thing this chunk is simulating [latching circuits by row and column]. I thought that I would try to replace the enumerated types in the array with pointers to functions and call them directly. This would be in lieu of the lookup+switch.
