• Switching back into the middle of a function in Actionscript

  - by J.Ded.

  I need to return to my original function after capturing an event (downloading something) with another function. The original function needs to return a value, which depends on the downloaded data. So, I'd like to pause original function for the time needed for the download and the eventhandler function to complete it's work, and resume it afterwards. The obvious way is to set a flag value (both the original function and the eventhandler are within the same class) and make the original function check it until the eventhandler function changes the flag. But that would be wasteful, and my AS is slow enough already:) [other parts of the application utilise some heavy graphics]. Is there another way? Like an event that gets captured "in the middle" of the function? Or some other form of flow control?

• ORACLE and TRIGGERS (inserted, updated, deleted)

  - by vandalo

  Hello, I would like to use a trigger on table which will be fired every time a row is inserted, updated, deleted. I wrote something like this: CREATE or REPLACE TRIGGER test001 AFTER INSERT OR DELETE OR UPDATE ON tabletest001 REFERENCING OLD AS old_buffer NEW AS new_buffer FOR EACH ROW WHEN (new_buffer.field1 = 'HBP00') and it works. Since I would like to do the same things if the row is inserted, updated or deleted I would like to know what's happening in the trigger. I think I can manage to find if the row in inserted or updated (I can check the old_buffer with the new_buffer). How can I know if the row has been deleted? Alberto

• boost test case for function taking user input

  - by oadams

  I have a function that takes in user input via std::cin: std::getline(std::cin, in); and creates a corresponding data structure by matching it with a regular expression. The function then returns this data structure. I'm using boost.test and I want to create a unit test to check that the output data type is correct given some inputs. However I don't know how to go about it since the input isn't passed as an argument to the function. EDIT: Is there a simple way to create a boost test case that feeds the function a string via standard input?

• Using TFS source control - how to remove files

  - by arame3333

  I am a lone developer, and I am now using TFS 2010, having until recently used VSS. I have not found it easy to get any books for beginners to help me use this. So I have now got my project in source control. But when I check in I get references to a number of files that I no longer use. How do I remove files from the TFS Source Control repository? So in the example below you can see lots of files from different projects that I do not want to see.

• Why is Drupal writing to root and not sites/default/files?

  - by Candland

  I'm using Drupal 6.14 on Win7. Everything seems to work except files that should be written to sites/default/files are trying to be written to /. The site was moved from a linux installation, which is writing the files correctly. I have setup a web.config w/ the rewrite rules for drupal. Not sure what or where else I should check. Thanks for any help. <rule name="Drupal Clean URLs" stopProcessing="true"> <match url="^(.*)$" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> </conditions> <action type="Rewrite" url="index.php?q={R:1}" appendQueryString="true" /> </rule>

• MYSQL to UPDATE table if row with 2 specific columns exist or INSERT new row if it does not exist

  - by user2509541

  I have a MYSQL table that looks as follows: id id_jugador id_partido team1 team2 1 2 1 5 2 2 2 2 1 1 3 1 2 0 0 I need to create a query to either INSERT new rows in the table or UPDATE the table. The condition is based on id_jugador and id_partido, meaning that if I wanted to insert id_jugador = 2 and id_partido = 1, then it should just UPDATE the existing row with the new team1 and team2 values I am sending. And dont duplicate the row. However, if I have an entry id_jugador=2 and id_partido=3, since this combination does not exist yet, it should add the new row. I read about the REPLACE INTO but it seems to be unable to check combination of UNIQUE KEYS.

• Getting the dynamic value of a checkbox in repeating region loop with Jquery

  - by John

  How do I get the values of a check box that is in a repeating region with its values dynamically generated from a recordset from the database.I want to retrieve the value when it is checked and after I click on a link.The problem is that it is retrieving only the first value of the recordset which is 1.This is the code: //jQuery $(document).ready(function(){ $("#clickbtn").click(function(){ $("input[type=checkbox][checked]").each(function(){ var value=$("#checkid").attr('value'); $("#textfield").attr('value',value); }); return false; }); }); //html <td width="22"><form id="form1" name="form1" method="post" action=""> <input type="checkbox" name="checkid" id="checkid" value="<?php echo $row_people['NameID']; ?>" /> </form></td> I would appreciate the help.

• PhotobucketNet photo upload

  - by n1tr0

  I have a problem with PhotobucketNet user login(I need user to login so I can upload a picture from HDD to his Photobucket account). Photobucket photobucket = new Photobucket("myapikey", "myapisecret"); photobucket.LaunchUserLogin(); // the problem happens here photobucket.RequestUserToken(); If I call RequestUserToken() it will happen immediately, so I'll get a crash cause user didn't logged in, and there is no event that's been raised after user logs in. Is there some variable(bool or something else) that I can check to see if user logged in - maybe to put it in a loop with timer? Also is their a way to know if user canceled logging in? I know that timer isn't a good solution, so if anyone has anything better as an idea, I'm open for any suggestions...

• In Spring MVC, is it possible to have different return types in one request handler method?

  - by Bobo

  For example, if a request succeeds, I will return a View ,if not, return a String indicating error message and set the content-type to either xml or json. Based on what I read, seems like I should use "void" as the return type for handler methods. Check this out: "void if the method handles the response itself (by writing the response content directly, declaring an argument of type ServletResponse / HttpServletResponse for that purpose) or if the view name is supposed to be implicitly determined through a RequestToViewNameTranslator (not declaring a response argument in the handler method signature)."(Spring Framework reference). What I dont understand is what " the view name is supposed to be implicitly determined through a RequestToViewNameTranslator (not declaring a response argument in the handler method signature)" means? Any anyone give me an example?

• Modify an MP3 slightly to change the data appearence

  - by Léon Pelletier

  I'm thinking about encrypting MP3s in a database, so that when user is downloading them with his software desktop player, only the software can decrypt them. This part is not a problem. The problem is I don't want a user to upload an mp3 to the database, then check which changes have been made to the file so he can reverse-engineer the file or at least see which algorithm is used to encrypt the files. So, user uploads MP3-A, then it becomes MP3-B because it has been modified, and I encrypt it to MP3-C. And when decrypted, it sounds 99.99% like MP3-A. I know MP3 format is lossy, but I wonder if there's a way to convert audio with limited loss, or if I need to forget it right now.

• I'm looking for a blend mode that gives 'realistic' paint colors. (Subtractive)

  - by almosnow

  I've been looking for a blend mode to (well ...) blend two RGB pixels in order to build colors in the samw way that a painter builds them (i.e: subtractive). Here are quick examples of the type of results that I'm expecting: CYAN + MAGENTA = BLUE CYAN + YELLOW = GREEN MAGENTA + YELLOW = RED RED + YELLOW = ORANGE RED + BLUE = PURPLE YELLOW + BLUE = GREEN I'm looking for a formula, like: dest_red = first_red + second_red; dest_green = first_green + second_green; dest_blue = first_blue + second_blue; I've tried with the commonly used 'multiply' formula but it doesn't work; I've tried with custom made formulas but I'm still not able to 'crack' how it should work. And I know already a lot of color theory so please refrain from answers like: Check this link: http://the_difference_betweeen_additive_and_subtractive_lightning.html

• How can I Find out what BCL types a custom type is using its method?

  - by dotnetdev

  If I have a class, eg T1, and I want to know what classes in the BCL it is using, how could I do this? I came up with this: T1.GetType().GetMethods().Where(x => x.DeclaringType.Namespace == "System"); But this will get all methods in my custom type, but I want to look inside each Method, so I was hoping I could do something like: T1.GetType().GetMethods().BodyTypesUsed; to check if my method uses a type like Streamwriter. How could I achieve this?

• How Can I Determine if HTTP Requests/Responses are compressed in IE7?

  - by DTS

  I'm trying to use Fiddler (v2.2.2.0) to see if HTTP traffic through IE7 is being compressed. I'm not seeing Accept-Encoding or Content-Encoding request/response headers being sent/returned and I do not need to decode the response data once it's arrived, which leads me to believe that the responses are NOT coming back compressed. However, when making the same requests using FireFox 3.5.7, I could see through FireBug that FF was sending Accept-Encoding and YSlow at least thought my data was coming back compressed. A comment in this question: http://stackoverflow.com/questions/897989/using-fiddler-to-check-iis-compression suggested that a proxy server may be to blame for stripping out headers and decompressing the content for security reasons. I am using Verizon FIOS for my broadband at home and am now wondering if Verizon is proxying my HTTP traffic? In short, how can I positively confirm/deny that responses are coming back compressed through IE? Thanks.

• Oracle checking existence before deletion in a trigger

  I have analyzed a hibernate generated oracle database and discovered that a delete of a row from a single table will spawn the firing of 1200+ triggers in order to delete the related rows in child tables. The triggers are all auto-generated the same - an automatic delete of a child row without checking for existence first. As it is impossible to predict which child tables will actually have related rows, I think a viable solution to preventing the firing of the cascaded delete down a deeply branched completely empty limb, would be to check for the existence of a related row before attempting to delete. In other dbms', I could simply state " if exists....." before deleting. Is there a comparable way to do this in oracle?

• MySQL Join a Table if Exists Question

  - by swhitlow

  I have a DB which has a table called "config". This table could possibly have a "config_cstm" table that is related by the id to the config table. I was wondering - is there a way to dynamically check for the existence of this table in one simple select statement? In other words, something like: "select * from config (IF EXISTS config_cstm THEN LEFT OUTER JOIN config_cstm ON config.id = config_cstm.id_c" I know how I would go about checking for the existence of an existing table in PHP. I was wanting to do this all in one MySQL statement though. Any suggestions? Thanks!

• only return random number when it is unique

  - by phil

  My brain is melting today and i cannot think how to do this simple bit of code. numberList is a string of numbers seperated by commas like '2, 34, 10' etc.. when i request a random number i need to check if the string has the number, if it does i want to keep requesting a random number until the random number is definitely not in the string. i cant think what kind of loop i would do to get this to work: Random r = new Random(); public int RandomPos(int max) { int i; do { i = r.Next(max) + 1; } while (!numberList.Contains(i.ToString())); return i; }

• Using try vs if in python

  - by artdanil

  Is there a rationale to decide which one of try or if constructs to use, when testing variable to have a value? For example, there is a function that returns either a list or doesn't return a value. I want to check result before processing it. Which of the following would be more preferable and why? result = function(); if (result): for r in result: #process items or result = function(); try: for r in result: #process items except TypeError: pass; Related discussion: Checking for member existence in Python

• How do stop form posting to mysql if database contains a specific ID?

  - by user342391

  I have a form that I am using to post data to mysql. Before submitting the form I want to check the database and see if there are any fields in the column 'customerid' that equal 'userid' and if so not to post the form. Basically, I am trying to limit my users from posting more than once. Users will be able to login to my system and make ONE post. They will be able to delete and modify their post but are only limited to one post. How would I do this??? Code so far: <?php include '../login/dbc.php'; page_protect(); $userid = $_SESSION['user_id']; $sql="INSERT INTO content (customerid, weburl, title, description) VALUES ('$_POST[userid]','$_POST[webaddress]','$_POST[pagetitle]','$_POST[pagedescription]')"; if (!mysql_query($sql)) { die('Error: ' . mysql_error()); } echo "1 record added"; ?>

• Is it a good design to return value by parameter?

  - by aztack

  bool is_something_ok(int param,SomeStruct* p) { bool is_ok = false; // check if is_ok if(is_ok) // set p to some valid value else // set p to NULL return is_ok; } this function return true and set p to a valid value if "something is ok" otherwise return false and set p to NULL Is that a good or bad design? personally, i feel uncomfortable when i use it. If there is no document and comment, i really don know how to use it. BTW:Is there some authoritative book/article about API design?

• How can I determine new & previous cell value on SheetChange event in Excel?

  - by Falco Foxburr

  I have some special cells in my Excel workbooks which are managed by my Excel Add-in. I want to prevent users from changing content of those cells, but I also want to know, what value users wanted to enter to those cells. On the SheetChange event I can check what users entered to my special cells, but how do I determine the PREVIOUS value in those cells and REVERT user changes? It is not a solution for me. If I lock cell in Excel, it becomes read-only - user can not even try to enter anything to this cell - Excel popups warning dialog in this case. My problem is that I want to catch what user entered to my cell, do something with this value, and then revert cell content to original value.

• SQL Server: Find Values that don't exist in a table

  - by MacAnthony

  I have a list or set of values that I would like to know which ones do not currently exist in a table. I know I can find out which ones do exist with: SELECT * FROM Table WHERE column1 IN (x,x,x,x,x) The set is the values I am checking against. Is there a way to find out which values in that set do not exist in column1? Basically, I'm looking for the inverse of the sql statement above. This is for a report, so all I need is the values that don't exist to be returned back. I have and could do this with a left join and putting the values in another table, but the values I check are always different and was hoping to find a solution that didn't involve clearing a table and inserting data first. Trying to find a better solution for me if one exists.

• jUnit same exception in different cases

  - by coubeatczech

  Hi, I'm writing a jUnit test for a constructor that parses a String and then check numerous things. When there's wrong data, for every thing, some IllegalArgumentException with different message is thrown. So I would like to write tests for it, but how can i recognize what error was thrown? This is how can I do it: @Test(expected=IllegalArgumentException.class) public void testRodneCisloRok(){ new RodneCislo("891415",dopocitej("891415")); } and this is how I would like to be, but I don't know if it is possible to write it somehow: @Test(expected=IllegalArgumentException.class("error1")) public void testRodneCisloRok(){ new RodneCislo("891415",dopocitej("891415")); }

• Can a thread call wait() on two locks at once in Java (6)

  - by Dr. Monkey

  I've just been messing around with threads in Java to get my head around them (it seems like the best way to do so) and now understand what's going on with synchronize, wait() and notify(). I'm curious about whether there's a way to wait() on two resources at once. I think the following won't quite do what I'm thinking of: synchronized(token1) { synchronized(token2) { token1.wait(); token2.wait(); //won't run until token1 is returned System.out.println("I got both tokens back"); } } In this (very contrived) case token2 will be held until token1 is returned, then token1 will be held until token2 is returned. The goal is to release both token1 and token2, then resume when both are available (note that moving the token1.wait() outside the inner synchronized loop is not what I'm getting at). A loop checking whether both are available might be more appropriate to achieve this behaviour (would this be getting near the idea of double-check locking?), but would use up extra resources - I'm not after a definitive solution since this is just to satisfy my curiosity.

• Strings - Filling In Leading Zeros Wtih A Zero

  - by headscratch

  I'm reading an array of hard-coded strings of numeric characters - all positions are filled with a character, even for the leading zeros. Thus, can confidently parse it using substring(start, end) to convert to numeric. Example: "0123 0456 0789" However, a string coming from a database does not fill in the leading zero with a 'zero character', it simply fetches the '123 456 789', which is correct for an arithmetic number but not for my needs and makes for parsing trouble. Before writing conditionals to check for leading zeros and adding them to the string if needed, is there a simple way of specifying they be filled with a character ? I'm not finding this in my Java book... I could have done the three conditionals in the time it took to post this but, this is more about 'education'... Thanks
