• Auto Re-Running of Tests that fail

  - by Tangopop

  I have a set of Selenium/MbUnit Tests that work fine, but tend to take a while to run (over 4 hours) A problem i am finding is that about 1 in 20 test seems to timeout when running. I have confirmed the Selenium GRID is working and the Selenium RC's are all fine, it just seems to be a qwerk of the system. What is really annoying though is that if i run these tests again they will usually pass. What i want to know is if there is a way for me to auto rerun the tests (probably in the code) if a perticular type of exception is caught... I have attempted to put a few lines of code in the catch statement but i know this is a very hacky way of re running the tests. Here is the code: catch (AssertionException e) { if (e.Message() == "TimeOut") //Something similar to this { this.Test(); } else { verificationErrors.AppendLine(browserList[i] + " :: " + e.Message); } } Any suggestions?

• Date or String declaration in a javabean

  - by Jeff

  Should I declare an attribute in a javabean that holds a date value a user types in on an HTML form as a String or Date? I feel I should declare as a Date, however, since I do server validation on all form data, if the date doesn't validate, when I pass the form bean back to the jsp view for correcting, I lose the date value that the user tried to type in. If I declare as a String, if the date doesn't validate, I'm able to set the string value in the bean and pass the bean back to the view and the user can see what they incorrectly typed. But with a String declaration for Date inputs I forsee problems down the road with my DAO. I want to be able to use a DAO utility which generates a prepare statement using setObject. In my html form I request dates to be mm/dd/yyyy and in DAO i'm using Oracle Date. I can not use hibernate or such, since this is a corporate intranet. What is the best practice "pattern" I should be following??

• Error messages in ASP.NET with jQuery UI

  - by eugeneK

  I've been using my own Error reporting module which was combination of simple c# and jQueryUI Dialog. Problem is that once error or success occurs i do write it's value to session. It does work pretty good on pages with Responce.Redirect on error but not on pages where i catch an error and then return to same form. My question is why does session which added pre-postback fails to load in pages where i have return statement on some condition. And if there another way to save errors and success message except in session ? Maybe global variables or something like that ...

• C++ Generic List Assignment

  - by S73417H

  I've clearly been stuck in Java land for too long... Is it possible to do the C++ equivalent of the following Java code: // Method List<Bar> getBars() { return new LinkedList<Bar>(); } // Assignment statement. List<Foo> stuff = getBars(); Where Foo is a sub-class of Bar. So in C++.... std::list<Bar> & getBars() { std::list<Bar> bars; return bars; } std::list<Foo> stuff = getBars(); Hope that makes sense....

• using Cookie-free Domains for Components

  - by JPro

  I was looking at the post here which says When the browser makes a request for a static image and sends cookies together with the request, the server doesn't have any use for those cookies. So they only create network traffic for no good reason. Although I tend not to use cookies at all, my doubt is I used to think that the server creates the cookies to store the session varialbles etc and sends to the client. But this statement says the reverse of that. I don't quiet understand what is the need for the browser to create and send cookies with the request, to me it doesn't make any sense?. Can anyone please correct me? Thanks/.

• jQuery selector to target any CSS name (of multiple present) starting with a prefix?

  - by John K

  I'm considering one selection statement that would target one of many css class names in a single class attribute value based on a string prefix. For example, I want any detail- prefixed class names to get targeted from the following sample links. <a href="eg.html" class="detail-1 pinkify another"> <a href="eg.html" class="something detail-55 minded"> <a href="eg.html" class="swing narrow detail-Z"> <a href="eg.html" class="swing narrow detail-Z detail-88 detail-A"> It's reminiscent of how [class|="detail"] prefix selector works on a scalar attribute value, and also of .hasClass(className), but my question needs both concepts applied simultaneously. Note: The detail- prefix won't necessarily be the first class name of the bunch.

• How do I return the numeric value from a database query in PHP?

  - by Luke

  Hello, I am looking to retreive a numerical value from the database function adminLevel() { $q = "SELECT userlevel FROM ".TBL_USERS." WHERE id = '$_SESSION[id]'"; return mysql_query($q, $this->connection); } This is the SQL. I then wrote the following php/html: <?php $q = $database->adminLevel(); if ($q > 7) { ?> <a href="newleague.php">Create a new league</a> <? } ?> The problem I have is that the userlevel returned isn't affecting the if statement. It is always displayed. How do i get it to test the value of userlevel is greater than 7? Thanks

• Could someone tell me if my C++ indent style is named? (example given)

  - by Maulrus

  I'm learning C++. For me, my programming style is just what looks the best; it doesn't seem to follow the rules of any one particular style. Here's an example void f(int x){ //no space between close-paren and bracket if (!x){ cout << "x is non-zero\n"; } //closing bracket indented to the same level as the original statement } It's only slightly different for something like a class or a namespace: class myClass {}; //space between class name and bracket, otherwise the same as functions K&R style does uses that kind of bracketing for statements, but my style uses it for everything. I'd like to know if there's a name for it so I can say simply what my indent style is without having to explain using examples like these.

• MySQL: Return grouped fields where the group is not empty, effeciently

  - by Ryan Badour

  In one statement I'm trying to group rows of one table by joining to another table. I want to only get grouped rows where their grouped result is not empty. Ex. Items and Categories SELECT Category.id FROM Item, Category WHERE Category.id = Item.categoryId GROUP BY Category.id HAVING COUNT(Item.id) > 0 The above query gives me the results that I want but this is slow, since it has to count all the rows grouped by Category.id. What's a more effecient way? I was trying to do a Group By LIMIT to only retrieve one row per group. But my attempts failed horribly. Any idea how I can do this? Thanks

• Javascript - document.links.className ?

  - by Slevin

  I have a Javascript question that I am curious about. When using: var test = document.links(arrayNum).name; Is it possible to dig deeper into specifying links? For instance, if there is just a group of links from within a div with an id that you would like to target as opposed to all the links on the page could you write something like: var test = document.getElementById('divId').links(arrayNum).name; Or could I add a class to the statement to target only the links associated with it? var test = document.links.className(arrayNum).name; Is anything like this feasible?

• Determining child count of path

  - by sqlnewbie

  I have a table whose 'path' column has values and I would like to update the table's 'child_count' column so that I get the following output. path | child_count --------+------------- | 5 /a | 3 /a/a | 0 /a/b | 1 /a/b/c | 0 /b | 0 My present solution - which is way too inefficient - uses a stored procedure as follows: CREATE FUNCTION child_count() RETURNS VOID AS $$ DECLARE parent VARCHAR; BEGIN FOR parent IN SELECT path FROM my_table LOOP DECLARE tokens VARCHAR[] := REGEXP_SPLIT_TO_ARRAY(parent, '/'); str VARCHAR := ''; BEGIN FOR i IN 2..ARRAY_LENGTH(tokens, 1) LOOP UPDATE my_table SET child_count = child_count + 1 WHERE path = str; str := str || '/' || tokens[i]; END LOOP; END; END LOOP; END; $$ LANGUAGE plpgsql; Anyone knows of a single UPDATE statement that does the same thing?

• Multiple column Union Query without duplicates

  - by Adam Halegua

  I'm trying to write a Union Query with multiple columns from two different talbes (duh), but for some reason the second column of the second Select statement isn't showing up in the output. I don't know if that painted the picture properly but here is my code: Select empno, job From EMP Where job = 'MANAGER' Union Select empno, empstate From EMPADDRESS Where empstate = 'NY' Order By empno The output looks like: EMPNO JOB 4600 NY 5300 MANAGER 5300 NY 7566 MANAGER 7698 MANAGER 7782 MANAGER 7782 NY 7934 NY 9873 NY Instead of 5300 and 7782 appearing twice, I thought empstate would appear next to job in the output. For all other empno's I thought the values in the fields would be (null). Am I not understanding Unions correctly, or is this how they are supposed to work? Thanks for any help in advance.

• Writing loops with i++ or ++i [duplicate]

  - by Nonesuch

  This question already has an answer here: Why use ++i instead of i++ in cases where the value is not used anywhere else in the statement? 6 answers format of for loops 31 answers I have a question about writing loops. I always begin with (int i=0; i<10; i++) But I see many experts begin with (int i=0; i<10; ++i) Is there there any real difference, or they are same? Of course, I know the difference between pre-increment and post-increment. I mean which one I should use when writing the loop? or it depends. Thanks!

• the correct actionscript to find if object already exists

  - by touB

  I have a Rect object that I'd like to create and set its properties only once. After that, I want to just modify its properties since it already exists. This is my general idea if(theRect == undefined){ Alert.show("creating"); var theRect:Rect = new Rect(); //then set properties addElement(theRect); //then add it using addElement because addChild() does not work } else { Alert.show("updating"); //no need to create it since it's already been created //just access and change the properties } I tried several ways and combinations for the if conditional check: if(theRect == undefined){ if(theRect == null){ declaring and not declaring `var theRect:Rect;` before the if check declaring and instantiating to null before the if check `var theRect:Rect = null;` but can't get the desired effect. Everytime this code block runs, and depending on which version I've used, it either gives me a "can't access null object" error or the if statement always evaluates to true and creates a new Rect object and I get the "creating" Alert. What's the right way of creating that Rect but only if doesn't exist?

• Python: Check if all dictionaries in list are empty

  - by Brant

  I have a list of dictionaries. I need to check if all the dictionaries in that list are empty. I am looking for a simple statement that will do it in one line. Is there a single line way to do the following (not including the print)? l = [{},{},{}] # this list is generated elsewhere... all_empty = True for i in l: if i: all_empty = False print all_empty Somewhat new to python... I don't know if there is a shorthand built-in way to check this. Thanks in advance.

• Prevent Excel from evaluating unneeded expressions in OR()

  - by Wesley

  IF(OR(ISNA(MATCH(8,B10:B17,0)),MATCH(8,B10:B17,0)>8),"",...BLAH...) I understand how to fix this problem by rearranging my formula. I have it the way it is to show this point. You can see the OR() statement checks to see if the first MATCH() returns NA. When it does, OR() should automatically return TRUE and not evaluate the second MATCH() because conditions have been met for the OR() to return true no matter what other arguments there are. You'll notice that the first and second MATCH() functions do the same thing. What's happening is the entire function is returning NA because the second MATCH() is executing even though it doesn't have to, the OR() has been satisfied with one TRUE, therefore the function should return "". Is this a bug or is this intentional?

• Selecting data effectively sql

  - by learner135

  Hi, I have a very large table with over 1000 records and 200 columns. When I try to retreive records matching some criteria in the WHERE clause using SELECT statement it takes a lot of time. But most of the time I just want to select a single record that matches the criteria in the WHERE clause rather than all the records. I guess there should be a way to select just a single record and exit which would minimize the retrieval time. I tried ROWNUM=1 in the WHERE clause but it didn't really work cause I guess the engine still checks all the records even after finding the first record matching the WHERE criteria. Is there a way to optimize in case if I want to select just a few records? Thanks in advance. Edit: I am using oracle 10g.

• Returning a list in this recursive coi function in python.

  - by Nate

  Hello. I'm having trouble getting my list to return in my code. Instead of returning the list, it keeps returning None, but if I replace the return with print in the elif statement, it prints the list just fine. How can I repair this? def makeChange2(amount, coinDenomination, listofcoins = None): #makes a list of coins from an amount given by using a greedy algorithm coinDenomination.sort() #reverse the list to make the largest position 0 at all times coinDenomination.reverse() #assigns list if listofcoins is None: listofcoins = [] if amount >= coinDenomination[0]: listofcoins = listofcoins + [coinDenomination[0]] makeChange2((amount - coinDenomination[0]), coinDenomination, listofcoins) elif amount == 0: return listofcoins else: makeChange2(amount, coinDenomination[1:], listofcoins)

• Unrecognized libraries and functions

  - by John Smith

  I am working in Eclipse 3.7.2 on Ubuntu 12.04 with C++. I have read about a few instances where libraries were not being recognized and the majority said to update the Paths and Symbols but that hasn't fixed my issue. I have 2 projects open in my workspace, one of which is already a completed project that has implemented functions and libraries with no errors from Eclipse. However, when I try to implement some of the same functions or include the same libraries in the 2nd project Eclipse can't resolve them. For example, #include <string> #include <stdio.h> strstr(p, "<Project>"); The include statement will be accepted and stdio.h will be found but the strstr function is not resolved even though it works fine in the other project. Any ideas as to why this might be happening? Thanks.
