  • Good error flagging | PHP

    - by Wayne
    For everyone that was thinking of the error_reporting() function, then it isn't, what I need is whenever a MySQL query has been done, and the statement has like if($result) { echo "Yes, it was fine... bla bla"; } else { echo "Obviously, the echo'ing will show in a white page with the text ONLY..."; } Whenever statements have been true or false, I want the error to be appeared when redirected with the header() function and echo the error reporting in a div somewhere on the page. Basically something like this: $error = ''; This part appears inside the div tags <div><?php echo $error; ?></div> So the error part will be echoed when redirected with the header() if($result) { $error = "Yes, it was fine... bla bla"; header("Location: url"); } else { $error = "Something wrong happened..."; header("Location: url"); } But that just doesn't work :(

  • Does CSS have a "start over" feature?

    - by Rick Wayne
    I'm using calendar_date_select (henceforth CDS) in a Rails application, and have a stupid question. When I embed the CDS component in the middle of an already-CSS-styled page, all manner of things go ugly-wrong with it (spacing, fonts, etc.). Clearly the elements inside the CDS have inherited unwanted stuff from the styles already working in the containing page. Now, I could use a combination of, say, Safari's CSS debugging and analyze what's wrong element-by-element. But that's (A) tedious, and (B) might load up my component's styles with tons of container-defeating special cases. If nothing else, I'm certain to change the containing page's styles in the future and would have to maintain the special cases. My question: Is is possible to have a DIV in a page that essentially backs out all the existing styling? Is there a simple one-liner that will do this? Failing that, can it be done on an element-by-element basis? E.g. I know what tags the CDS generates, so I could list each of them: { p: "#--NOTHING--#"; a: "#--NOTHING--#"; } where #--NOTHING--# is the Magic Turn Off All Inherited Styles incantation. http://code.google.com/p/calendardateselect/ Thanks, peeps.

  • Formula to follow addition of rows

    - by Wayne McCaslin
    New to VBA, please help. I have a range say A2:D10; input causes rows to be added. New entries are being added using NextRow=_. Works perfectly, however, how do I get the formulas in columns C and D to follow each new row being added. I cannot just format entire column due to my sort criteria. Example formula is =IF(ISTEXT($B11),$C$2-$D11,"")

  • Optimizing a memoization decorator not increase call stack

    - by Tyler Crompton
    I have a very, very basic memoization decorator that I need to optimize below: def memoize(function): memos = {} def wrapper(*args): try: return memos[args] except KeyError: pass result = function(*args) memos[args] = result return result return wrapper The goal is to make this so that it doesn't add on to the call stack. It actually doubles it right now. I realize that I can embed this on a function by function basis, but that is not desired as I would like a global solution for memoizing. Any ideas?

  • How do you get "in the zone"?

    - by Wayne Werner
    Hi, I've just started my first real programming job and am pleased to discover that this is exactly what I want to do for the rest of my life. When it comes round to ~1 hour before it's time to go home and I think "Man, do I have to go home already?" I'd say that's A Good Thing(tm). One thing I've discovered though is that it takes a little while for my brain to get "in gear" or "in the Zone", so I'm curious what other folks do to get programming at their prime. My current flow is when I get here I visit SO and look at the interesting problems - I find it helps get my brain moving. After 20-30 minutes I start looking at my code/specs/etc to decide what I want/need to work on first. So how do you get started?

    Hey, i'm just doing some testing on Visual Studio 2008, what i'm trying to do is to change the text colour inside the multi-textfield which isn't working and I don't know why... Public Class Form1 Dim ColourValue As Color Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load rbBlue.Checked = False rbRed.Checked = False rbGreen.Checked = False End Sub Private Sub rbRed_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbRed.CheckedChanged txtSpace.BackColor = Color.Red End Sub Private Sub rbBlue_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbBlue.CheckedChanged txtSpace.BackColor = Color.Blue End Sub Private Sub rbGreen_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbGreen.CheckedChanged txtSpace.BackColor = Color.Green End Sub Private Sub cbColours_SelectedValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles cbColours.SelectedValueChanged ColourValue = cbColours.SelectedValue txtSpace.BackColor = ColourValue End Sub End Class Basically i have the radio buttons that would change the background colour of the textfield, but i just need the dropdown menu to change the text colour. Many thanks :)

  • Lisp data security/validation

    - by Wayne Werner
    This is really just a conceptual question for me at this point. In Lisp, programs are data and data are programs. The REPL does exactly that - reads and then evaluates. So how does one go about getting input from the user in a secure way? Obviously it's possible - I mean viaweb - now Yahoo!Stores is pretty secure, so how is it done?

  • Account activation PHP

    - by Wayne
    I created this account registration activation script of my own, I have checked it over again and again to find errors, I don't see a particular error... The domain would be like this: http://domain.com/include/register.php?key=true&p=AfRWDCOWF0BO6KSb6UmNMf7d333gaBOB Which comes from an email, when a user clicks it, they get redirected to this script: if($_GET['key'] == true) { $key = $_GET['p']; $sql = "SELECT * FROM users WHERE user_key = '" . $key . "'"; $result = mysql_query($sql) or die(mysql_error()); if(mysql_affected_rows($result) > 0) { $sql = "UPDATE users SET user_key = '', user_active = '1' WHERE user_key = '" . $key . "'"; $result = mysql_query(sql) or die(mysql_error()); if($result) { $_SESSION['PROCESS'] = $lang['Account_activated']; header("Location: ../index.php"); } else { $_SESSION['ERROR'] = $lang['Key_error']; header("Location: ../index.php"); } } else { $_SESSION['ERROR'] = $lang['Invalid_key']; header("Location: ../index.php"); } } It doesn't even work at all, I looked in the database with the user with that key, it matches but it keeps coming up as an error which is extremely annoying me. The database is right, the table and column is right, nothing wrong with the database, it's the script that isn't working. Help me out, guys. Thanks :)

  • MySQL Query exceptions

    - by Wayne
    In one page, it should show records that has the following selected month from the drop down menu and it is set in the ?month=March So the query will do this $sql = "SELECT * FROM schedule WHERE month = '" . Clean($_GET['month']) . "' AND finished='0' ORDER BY date ASC"; But it shows records that has a value of 2 in the finished column and I don't want the query to include this. I've tried $sql = "SELECT * FROM schedule WHERE month = '" . Clean($_GET['month']) . "' AND finished='0' OR finished = '1' OR finished = '3' ORDER BY date ASC"; But it shows records on different months when it shouldn't be. So basically I want the record to exclude the records that has the value of 2 in the record that will not be shown in the page.

  • Is there a lightweight datagrid alternative in Flex ?

    - by Wayne
    What is the most performant way of displaying a table of data in Flex? Are there alternatives to the native Flex Datagrid Component? Alternatives that are noted for their rendering speed? Are there other ways to display a table? I have a datagrid with roughly 70 lines and 7 columns of simple text data. This is currently created and loaded in memory. This is being refreshed rapidly (about 800 msec) and there is a slight lag in other animations when it is rendering the table... So I am trying to cut down this render time.

  • How to handle recurring dates (dates only) in .NET?

    - by Wayne M
    I am trying to figure out a good way to handle recurring events in .NET, specifically for an ASP.NET MVC application. The idea is that a user can create an event and specify that the event can occur repeatedly after a specific interval (e.g. "every two weeks", "once a month" and so on). What would be the best way to tackle this? My brainstorming right now is to have two tables: Job and RecurringJob. Job is the "master" record and has the description of the job as well a key to what customer it's for, while RecurringJob links back to Job and has additional info on what the occurrence frequency is (e.g. 1 for "once a month") as well as the timespan (e.g. "Weekly", "Monthly"). The issue is how to determine and set the next occurrence of the job since this will have to be something that's done regularly. I've seen two trains of thought with this: This logic should either be stored in a database column and periodically updated, or calculated on the fly in the code. Any thoughts or suggestions on tackling this? Edit: this is for a subscription based web app I'm creating to let service businesses schedule their common recurring jobs easily and track their customers. So a typical use might be to create a "Cut lawn" job for Mr Smith that occurs every month The exact date isn't important - it's the ability for the customer to see that Mr Smith gets his lawn cut every month and followup with him about it. Let me rephrase the above to better convey my idea. A sample use case for the application might be as follows: User pulls up the customer record for John Smith and clicks the Add Job link. The user fills out the form to create a job with a name of "Cut lawn", a start date of 11/15/2009, and selects a checkbox indicating that this job continually occurs. The user is presented with a secondary screen asking for the job frequency. The user indicates (haven't decided how at this point - let's assume select lists) that the job occurs once a month. User clicks save. Now, when the user views the record for John Smith, they can see that he has a job, "Cut lawn", that occurs every month starting from 11/15/2009. On the main dashboard when it's one week prior to the assumed start date, the user sees the job displayed with an indicator such as "12/15/2009 - Cut lawn (John Smith)". A week before the due date someone from the company calls him up to schedule and he says he's going to be out of town until 1/1/2010, so he wants his appointment rescheduled for that date. Our user can change the date for the job to be 1/1/2010, and now the recurrence will start one month from that date (e.g. next time will be 2/1/2010). The idea behind this is that the app is targeting businesses like lawn care, plumbers, carpet cleaners and the like where the exact date isn't as important (because it can and will change as people are busy), the key thing is to give the business an indicator that Mr. Smith's monthly service is coming up, and someone should give him a call to determine when exactly it can be scheduled for. In effect give these businesses a way to track repeat business and know when it's time to followup with a customer.

  • Android which button index from array was pressed

    How do I set up a OnClickListener to simply tell me which index button was pressed from an array of buttons. I can change text and color of these buttons using the array. I set them up like this. TButton[1] = (Button)findViewById(R.id.Button01); TButton[2] = (Button)findViewById(R.id.Button02); TButton[3] = (Button)findViewById(R.id.Button03); up to 36.

  • Async WebRequest Timeout Windows Phone 7

    - by Tyler
    Hi All, I'm wondering what the "right" way of timing out an HttpWebRequest is on Windows Phone7? I've been reading about ThreadPool.RegisterWaitForSingleObject() but this can't be used as WaitHandles throw a Not implemented exception at run time. I've also been looking at ManualReset events but A) Don't understand them properly and B) Don't understand how blocking the calling thread is an acceptable way to implement a time out on an Async request. Here's my existing code sans timeout, can someone please show me how I would add a timeout to this? public static void Get(Uri requestUri, HttpResponseReceived httpResponseReceivedCallback, ICredentials credentials, object userState, bool getResponseAsString = true, bool getResponseAsBytes = false) { var httpWebRequest = (HttpWebRequest)WebRequest.Create(requestUri); httpWebRequest.Method = "GET"; httpWebRequest.Credentials = credentials; var httpClientRequestState = new JsonHttpClientRequestState(null, userState, httpResponseReceivedCallback, httpWebRequest, getResponseAsString, getResponseAsBytes); httpWebRequest.BeginGetResponse(ResponseReceived, httpClientRequestState); } private static void ResponseReceived(IAsyncResult asyncResult) { var httpClientRequestState = asyncResult.AsyncState as JsonHttpClientRequestState; Debug.Assert(httpClientRequestState != null, "httpClientRequestState cannot be null. Fatal error."); try { var webResponse = (HttpWebResponse)httpClientRequestState.HttpWebRequest.EndGetResponse(asyncResult); } }

  • Auto-complete/suggestion popup menu in GtkTextView

    - by Tyler
    I'm trying to create a system that will allow me to respond to the current text and auto-complete/suggest what should come next. For example if the user starts to type "Batm" then the system would respond with a menu showing the full completed word "Batman". Think of an IDE like Eclipse or Visual Studio and you get the idea. I understand how to create a popup menu in Gtk+ but what I don't understand is the following: How do I grab the word that the user is currently typing from a GtkTextView (or SourceView) so that I can do a lookup and offer suggestions? How do I position the menu in such a way that it sits next to the current text item (like it would in an IDE)? If anyone could offer suggestions or even a link to a tutorial or example on how to do this correctly I would be forever grateful. As always thanks for you help! Programming language: C

  • Grab triangles within a lower triangle

    - by Tyler Rinker
    I have the need to grab all the thee element triangles that make up the lower triangle of a symmetric matrix. I can not think of how to grab all these pieces in the order of far left column working down and then next column to the right and so on. I know that the numbe rof mini triangles inside of the lower triangle is: n = x(x - 1)/2 where: x = nrow(mats[[i]]) Here I've created three matrices with letters (it's easier for me to conceptualize this way) and the elements in the order I'm looking for: FUN <- function(n) { matrix(LETTERS[1:(n*n)], n) } mats <- lapply(3:5, FUN) So this is the output I'd like to get (I put it in code rather than output format) for each of the matrices created above: list(c("B", "C", "F")) list(c("B", "C", "G"), c("C", "D", "H"), c("G", "H", "L")) list(c("B", "C", "H"), c("C", "D", "I"), c("D", "E", "J"), c("H", "I", "N"), c("I", "J", "O"), c("N", "O", "T")) How can I do this task in the fastest manner possible while staying in base R? Not sure if this visual of what I'm after is helpful but it may be:

  • Paginating data, has to be a better way

    - by John Tyler
    I've read like 10 or so "tutorials", and they all involve the same thing: Pull a count of the data set Pull the relevant data set (LIMIT, OFFSET) IE: SELECT COUNT(*) FROM table WHERE something = ? SELECT * FROM table WHERE something =? LIMIT ? offset ?` Two very similar queries, no? There has to be a better way to do this, my dataset is 600,000+ rows and already sluggish (results are determined by over 30 where clauses, and vary from user to user, but are properly indexed of course).

  • Merge computed data from two tables back into one of them

    - by Tyler McHenry
    I have the following situation (as a reduced example). Two tables, Measures1 and Measures2, each of which store an ID, a Weight in grams, and optionally a Volume in fluid onces. (In reality, Measures1 has a good deal of other data that is irrelevant here) Contents of Measures1: +----+----------+--------+ | ID | Weight | Volume | +----+----------+--------+ | 1 | 100.0000 | NULL | | 2 | 200.0000 | NULL | | 3 | 150.0000 | NULL | | 4 | 325.0000 | NULL | +----+----------+--------+ Contents of Measures2: +----+----------+----------+ | ID | Weight | Volume | +----+----------+----------+ | 1 | 75.0000 | 10.0000 | | 2 | 400.0000 | 64.0000 | | 3 | 100.0000 | 22.0000 | | 4 | 500.0000 | 100.0000 | +----+----------+----------+ These tables describe equivalent weights and volumes of a substance. E.g. 10 fluid ounces of substance 1 weighs 75 grams. The IDs are related: ID 1 in Measures1 is the same substance as ID 1 in Measures2. What I want to do is fill in the NULL volumes in Measures1 using the information in Measures2, but keeping the weights from Measures1 (then, ultimately, I can drop the Measures2 table, as it will be redundant). For the sake of simplicity, assume that all volumes in Measures1 are NULL and all volumes in Measures2 are not. I can compute the volumes I want to fill in with the following query: SELECT Measures1.ID, Measures1.Weight, (Measures2.Volume * (Measures1.Weight / Measures2.Weight)) AS DesiredVolume FROM Measures1 JOIN Measures2 ON Measures1.ID = Measures2.ID; Producing: +----+----------+-----------------+ | ID | Weight | DesiredVolume | +----+----------+-----------------+ | 4 | 325.0000 | 65.000000000000 | | 3 | 150.0000 | 33.000000000000 | | 2 | 200.0000 | 32.000000000000 | | 1 | 100.0000 | 13.333333333333 | +----+----------+-----------------+ But I am at a loss for how to actually insert these computed values into the Measures1 table. Preferably, I would like to be able to do it with a single query, rather than writing a script or stored procedure that iterates through every ID in Measures1. But even then I am worried that this might not be possible because the MySQL documentation says that you can't use a table in an UPDATE query and a SELECT subquery at the same time, and I think any solution would need to do that. I know that one workaround might be to create a new table with the results of the above query (also selecting all of the other non-Volume fields in Measures1) and then drop both tables and replace Measures1 with the newly-created table, but I was wondering if there was any better way to do it that I am missing.

  • Best way to do syntax highlighting in GTK+?

    - by Tyler
    I was wondering if someone could point me to an example of (or just their thoughts on) the best way to code syntax highlighting in a C-based GTK+ application. I know that I can use the GtkTextTag to modify text in a GtkTextBuffer but beyond searching out keywords (iteratively or by regexing the string) is there a better way? My only concern is that if I wipe all of the tags and then re-search and apply the tags at every text change event it could really bog down my application. As always thanks for your help!
