• Can't read output of httpservice

  - by tag

  I have an HTTPservice that uses id="myhttp" url="site.com/script.php" method="POST" resultFormat="xml" script.php returns $output = '' . $worked . ''; echo $output; Problem is when I try to read worked, it tells me the variable worked is not there event.result.worked myhttp.lastResult.worked The only thing that works is using toString() myhttp.lastResult.toString() or event.result.toString() What am I doing wrong? I plan to add other variables to the output time, so need to access each time and worked separately. I may also need to return multiple responses each with their own worked and time values. How do I do that. I was thinking to not use XML. Is there a more lightweight option. Flex shows I have the following options: array e4x flashvars object text xml

• write 2d array to a file in C (Operating system)

  - by Bobj-C

  Hello All, I used to use the code below to Write an 1D array to a File: FILE *fp; float floatValue[5] = { 1.1F, 2.2F, 3.3F, 4.4F, 5.5F }; int i; if((fp=fopen("test", "wb"))==NULL) { printf("Cannot open file.\n"); } if(fwrite(floatValue, sizeof(float), 5, fp) != 5) printf("File read error."); fclose(fp); /* read the values */ if((fp=fopen("test", "rb"))==NULL) { printf("Cannot open file.\n"); } if(fread(floatValue, sizeof(float), 5, fp) != 5) { if(feof(fp)) printf("Premature end of file."); else printf("File read error."); } fclose(fp); for(i=0; i<5; i++) printf("%f ", floatValue[i]); My question is if i want to write and read 2D array ??

• static images aren't caching with php-generated page

  - by scootklein

  Our website was just converted to being generated by mod_rewrite and php scripts. Images aren't caching in browsers when they seemingly should be. All images follow format: <img src="/images/header.png" /> I must avoid the script completely caching because the PHP parser needs to handle each page dynamically on each request; however, the download overhead of the large images is cumbersome on every single page load. I would ideally provide headers for "Cache-Control: no-cache, must-revalidate" and "Expires: some_date_in_the_past" to force revalidation of the PHP script. Why isn't the browser caching static images with consistent href values across all pages?

• How to correct character encoding in IE8 native json ?

  - by mike_t2e

  I am using json with unicode text, and having a problem with the IE8 native json implementation. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script> var stringified = JSON.stringify("?????? olé"); alert(stringified); </script> Using json2.js or FireFox native json, the alert() string is the same as in the original one. IE8 on the other hand returns Unicode values rather than the original text \u0e2a\u0e27\u0e31\u0e2a\u0e14\u0e35 ol\u00e9 . Is there an easy way to make IE behave like the others, or convert this string to how it should be ? And would you regard this as a bug in IE, I thought native json implementations were supposed to be drop-in identical replacements for json2.js ?

• MySQL Query WHERE Including CASE or IF?

  - by handfix

  Strange problem. My Query looks like SELECT DISTINCT ID, `etcetc`, `if/elses over muliple joined tables` FROM table1 AS `t1` # some joins, eventually unrelated in that context WHERE # some standard where statements, they work/ CASE WHEN `t1`.`field` = "foo" THEN (`t1`.`anOtherField` != 123 AND `t1`.`anOtherField` != 456 AND `t1`.`anOtherOtherField` != "some String") WHEN `t1`.`field` = "bar" THEN `t1`.`aSecondOtherField` != 12345 END #ORDER BY CASE etc. Standard Stuff Apperantly MySQL returns a wrong rowcount and I think my problem is in the logic of the WHERE ... CASE statement. Maybe with the brackets? Maybe I should go for operator OR and not AND? Should my the second WHEN include brackets also, even when I only compare one field? Should I use IF and not CASE? Basically I want to exclude some rows with specific values IF theres a specific value in field foo or bar I would try that all out, but it takes a huge amount of time to complete that query... :(

• Convert Military time to string representation

  - by RRUZ

  I have an column declarated as int (called HourMil) wich store the time in military format. i need convert this values to an formated string (HH:MM) example HourMil = 710 -> must be 07:10 HourMil = 1305 -> must be 13:05 Actually i am using this code (and works ok) for convert the column HourMil to the string representation. SELECT SUBSTRING(LEFT('0',4-LEN(CAST(HourMil AS VARCHAR)))+CAST(HourMil AS VARCHAR),1,2)+':'+SUBSTRING(LEFT('0',4-LEN(CAST(HourMil AS VARCHAR)))+CAST(HourMil AS VARCHAR),3,2) FROM MYTABLE but I think this code can be improved.

• Insert new row with data computed from other rows

  - by Tyler McHenry

  Suppose I have a MySQL table called MyTable, that looks like this: +----+------+-------+ | Id | Type | Value | +----+------+-------+ | 0 | A | 1 | | 0 | B | 1 | | 1 | A | 2 | | 1 | B | 3 | | 2 | A | 5 | | 2 | B | 8 | +----+------+-------+ And, for each Id, I want to insert a new row with type C whose Value is the sum of the type A and B values for the rows of the same Id. The primary key on this table is (Id, Type), so there's no question of duplication of Id,Type pairs. I can create the rows I want with this query: SELECT MyTable_A.Id AS Id, 'C' AS Type, (A_Val + B_Val) AS Value FROM (SELECT Id, Value AS A_Val FROM MyTable WHERE Type='A') AS MyTable_A JOIN (SELECT Id, Value AS B_Val FROM MyTable WHERE Type='B') AS MyTable_B ON MyTable_A.Id = MyTable_B.Id Giving: +----+------+-------+ | Id | Type | Value | +----+------+-------+ | 0 | C | 2 | | 1 | C | 5 | | 2 | C | 13 | +----+------+-------+ But the question is: How do I use this result to insert the generated type-C rows into MyTable? Is there a relatively simple way to do this with a query, or do I need to write a stored procedure? And if the latter, guidance would be helpful, as I'm not too well versed in them.

• RegEx replace query to pick out wiki syntax

  - by Jeremy Thake

  I've got a string of HTML that I need to grab the "[Title|http://www.test.com]" pattern out of e.g. "dafasdfasdf, adfasd. [Test|http://www.test.com/] adf ddasfasdf [SDAF|http://www.madee.com/] assg ad" I need to replace "[Title|http://www.test.com]" this with "Title". What is the best away to approach this? I was getting close with: string test = "dafasdfasdf adfasd [Test|http://www.test.com/] adf ddasfasdf [SDAF|http://www.madee.com/] assg ad "; string p18 = @"(\[.*?|.*?\])"; MatchCollection mc18 = Regex.Matches(test, p18, RegexOptions.Singleline | RegexOptions.IgnoreCase); foreach (Match m in mc18) { string value = m.Groups[1].Value; string fulltag = value.Substring(value.IndexOf("["), value.Length - value.IndexOf("[")); Console.WriteLine("text=" + fulltag); } There must be a cleaner way of getting the two values out e.g. the "Title" bit and the url itself. Any suggestions?

• Indexing affects only the WHERE clause?

  - by andre matos

  If I have something like: CREATE INDEX idx_myTable_field_x ON myTable USING btree (field_x); SELECT COUNT(field_x), field_x FROM myTable GROUP BY field_x ORDER BY field_x; Imagine myTable with around 500,000 rows and most of field_x values being unique. Since I don't use any WHERE clause, will the created index have any effect at all in my query? Edit: I'm asking this question because I don't get any relevant difference between query-times before and after creating the index; They always take about 8 seconds (which, of course is too much time!). Is this behaviour expected?

• How to Create an Array from a Single Variable and Form Multiple Foreach Loops?

  - by matphoto

  I'm fairly proficient in HTML/CSS, but very new when it comes to the likes of PHP and Javascript. I've jumped headfirst into coding Wordpress shortcodes (basically php functions), and so far, through trial and error and seemingly endless browser refreshes, I've been able to figure everything out. I just hit a huge wall though, hence why I'm here. Basically, I'm trying to give an attribute a list of values like: attr="23, 95, 136, ect" The function then needs to take that attribute variable and create an array with it: $arr = array($attr); To me that seems as if it would work, but the array takes the whole list as one value instead. After doing that I want to create a foreach loop that parses each number from the list, possibly through yet another foreach loop if possible, and returns a section of code for each one, and I'm not quite sure how to pull that off either. Any feedback would be greatly appreciated.

• There has to be an easier way.. pulling data from mysql

  I need to pull 3 values from a table and assign each one to a variable each value is based on to columns, a type and an id $ht_live_query = mysql_query("SELECT htcode FROM coupon WHERE pid='$pid' AND type='L'"); $ht_live_result = mysql_fetch_array($ht_live_query); $htCODE_Live = $ht_live_result['htcode']; You can see that I am assigning the desired value to the variable $htL $ht_General_query = mysql_query("SELECT htcode FROM coupon WHERE pid='$pid' AND type='G'"); $ht_General_result = mysql_fetch_array($ht_General_query); $htCODE_General = $ht_General_result['htcode']; $ht_Reward_query = mysql_query("SELECT htcode FROM coupon WHERE pid='$pid' AND type='R'"); $ht_Reward_result = mysql_fetch_array($ht_Reward_query); $htCODE_Reward = $ht_Reward_result ['htcode']; I know I am doing this the hard way but can not figure out how to do the foreach or while loop to attain the desired results.

• PHP/Codeigniter processing a list with javascript

  - by user270797

  I have a list of items that the user can select. I want it to be more user friendly than standard checkboxes so I have seperate div's each with a unique id. When user clicks an item, I use javascript to display a tick on top of that item and change the style to show that it is highlighted. Im trying to work out how I can pass the list of id's when the form is submitted. Remember, if the user unticks an item, it should be removed from the list, I was thinking of using comma seperated values in a hidden text field but couldnt work out how to remove items from the start of the list if they were deselected

• Test-driven Development: Writing tests for private / protected variables

  - by Chetan

  I'm learning TDD, and I have a question about private / protected variables. My question is: If a function I want to test is operating on a private variable, how should I test it? Here is the example I'm working with: I have a class called Table that contains an instance variable called internalRepresentation that is a 2D array. I want to create a function called multiplyValuesByN that multiplies all the values in the 2D array by the argument n. So I write the test for it (in Python): def test_multiplyValuesByN (self): t = Table(3, 3) # 3x3 table, filled with 0's t.set(0, 0, 4) # Set value at position (0,0) to 4 t.multiplyValuesByN(3) assertEqual(t.internalRepresentation, [[12, 0, 0], [0, 0, 0], [0, 0, 0]]) Now, if I make internalRepresentation private or protected, this test will not work. How am I supposed to write the test so it doesn't depend on internalRepresentation but still tests that it looks correct after calling multiplyValuesByN?

• Android OpenGL deltaTime Measure issue

• hibernate transaction safety (with, without JBoss)

  - by Andy Nuss

  Hi, I am currently using just Hibernate and tomcat (no JBoss), and have hibernate transactions which I'm not clear on what transaction safety level I'm actually using, especially for those which read and get values and then update them). Thus I might be getting dirty reads? So I'm going to start having to study my transactions that require non-dirty reads, and make sure that (1) hibernate controls the transaction safety level of those transactions properly, and (2) be able to still have those transactions where dirty reads are ok. Do I need to install Hibernate with JBoss to control transaction safety levels? If so, what's the easiest way to do this without dramatically changing my application to use the J2EE apis, as I am currently using the basic Hibernate apis. Or better, can I get JTA control with Hibernate without using JBoss? Andy

• Separate groups of objects based on their properties

  - by Bevin

  I want to separate an array of my custom object into several arrays, based on the values of their two properties. The struct looks like this: struct MyStruct { public string Person { get; set; } public string Command { get; set; } } Now, if I have an array with a few objects: {Person1, cmd1} {Person1, cmd3} {Person2, cmd3} {Person3, cmd2} {Person2, cmd4} I want to be able to place them into one array for each person, that lists all of the commands for that person: {Person1: cmd1, cmd3} {Person2: cmd3, cmd4} {Person3: cmd2} I hope I've made it clear with my descriptions. I would assume that there is an elegant way to do this with LINQ, but I have no idea where to start.

When i click that text view it redirects to the tab2. it can be easily achieved by setCurrentTab(1) or setCurrentTabByTag("tab2") methods. But i want to pass lat and long values to that Map Activity to drop pin. What is the better way to use intents or getter/setter in java? What do you prefer? if your answer is "Intents". How?
