  • A global login (many sites)

    - by John
    We are a growing network but we figured we want to keep that the User only would need one account in order to access the network different sites. (Similar to Stackoverflow's login, If you login in to another "site" you use your account credentials and than your account is created). We want our own login system (Username, password) and not OpenId, as we'd probably have that in the future, but the main focus right now is the global login. How can I do this? Do a Curl request and send back a cookie? Have a "database" just for the login procedure and on first login also create a new "User" in the site specified database? Suggestions?.

  • jQuery Nested Droppables

    - by John
    I have a nested set of jQuery droppables...one outer droppable that encompasses most of the page and an a set of nested inner droppables on the page. The functionality I want is: If a draggable is dropped outside of any of the inner droppables it should be accepted by the outer droppable. If a draggable is dropped onto any of the inner droppables it should NOT be accepted by the outer droppable, regardless of whether the inner droppable accepts the draggable. So that would be easy if I could guarantee 1+ inner droppables would accept the draggable, because the greedy attribute would make sure it would only get triggered once. Unfortunately the majority of the time the inner droppable will also reject the draggable, meaning the greedy option doesn't really help. Summary: The basic functionality is a set of valid/invalid inner droppables to accept the draggable, but when you toss the draggable outside any of the draggables it gets destroyed by the outer droppable. What's the best way of doing this?

  • Best way to handle storing (possibly NULL) char * in a std::string

    - by John
    class MyClass { public: void setVar(const char *str); private: std::string mStr; int maxLength; //we only store string up to this length }; What's the best approach to implement setVar when the external code is quite likely to pass in NULL for an empty string (and cannot be changed)? I currently do something a bit like: void MyClass::setVar(const char *str) { mStr.assign(str ? str : "",maxLength); } But it seems kind of messy. ideas?

  • simple question about oracle indexes

    - by john
    If I have an oracle query like below: SELECT * FROM table_a where A = "1", B = "2", C = "3" for this query to pickup one of the indexes of table_a...does the index need to be on all 3 of these columns? What I am asking is: What if Index is on A, B, C, D? What if Index is on B, C? Will the index only be picked when it is on A, B, C?

  • How does this code block works?

    - by Justin John
    I can't understand how the following code works. $start = 1; while($start<10){ if ($start&1) { echo "ODD ".$start." <br/> "; } else { echo "EVEN ".$start." <br/> "; } $start++; } The $start&1 will return ODD and EVEN seperately. Output ODD 1 EVEN 2 ODD 3 EVEN 4 ODD 5 EVEN 6 ODD 7 EVEN 8 ODD 9 If we give $start&2 instead of $start&1, it returns with another order. How &1 &2 etc... works here?

  • How do I escape a new line character in a .ini file so that Zend_Config_Ini reads it literally?

    - by Nick
    I am trying to store a multiple line e-mail in an ini file using PHP/Zend Framework. My string has new lines characters in it, and when I use Zend_Config_Ini to parse the ini file, the new line characters come back escaped, so they are printed out on screen, instead of a line feed. Example: // ini file message = Hi {0},\n\nThis is a test message.\nGoodbye! is parsed by Zend_Config_Ini as: Hi {0},\\n\\nThis is a test message.\\nGoodbye! which then is printed out in the email as: Hi John,\n\nThis is a test message.\nGoodbye! Instead I want the e-mail to look like this: Hi John, This is a test message. Goodbye! Does anybody know how to achieve this? Thanks!

  • python check value not in unicode list

    Hi, I have a list and a value and want to check if the value is not in the list. list = [u'first record', u'second record'] value = 'first record' if value not in list: do something however this is not working and I think it has something to do with the list values having a u at the start, how can I fix this? And before someone suggests the list is returned from Django queryset so I can't just take the u out of the code :) Thanks

  • Non-empty list with null elements returned from Hibernate query

    - by John
    Hi, I'm new to hibernate so not sure if this is an expected behaviour, anyway: Session session = (Session)entityManager.getDelegate(); Criteria criteria = session.createCriteria(myRequest.class); criteria.add(Restrictions.eq("username", username)); criteria.setProjection(Projections.max("accesscount")); List<myRequest> results = criteria.list(); The returned results is a non-empty list with a single null element. I can't think of any reason why it should behave this way, any idea if this is the expected behaviour or have I done something wrong? System is on hibernate/Syabse. Thanks.

  • Nesting if else statements in PHP to validate a URL

    - by John
    I'm currently writing up a function in order to validate a URL by exploding it into different parts and matching those parts with strings I've defined. This is the function I'm using so far: function validTnet($tnet_url) { $tnet_2 = "defined2"; $tnet_3 = "defined3"; $tnet_5 = "defined5"; $tnet_7 = ""; if($exp_url[2] == $tnet_2) { #show true, proceed to next validation if($exp_url[3] == $tnet_3) { #true, and next if($exp_url[5] == $tnet_5) { #true, and last if($exp_url[7] == $tnet_7) { #true, valid } } } } else { echo "failed on tnet_2"; } } For some reason I'm unable to think of the way to code (or search for the proper term) of how to break out of the if statements that are nested. What I would like to do check each part of the URL, starting with $tnet_2, and if it fails one of the checks ($tnet_2, $tnet_3, $tnet_5 or $tnet_7), output that it fails, and break out of the if statement. Is there an easy way to accomplish this using some of the code I have already?

  • is "else if" faster than "switch() case" ?

    - by John
    Hello, I'm an ex Pascal guy,currently learning C#. My question is the following: Is the code below faster than making a switch? int a = 5; if (a == 1) { .... } else if(a == 2) { .... } else if(a == 3) { .... } else if(a == 4) { .... } else .... And the switch: int a = 5; switch(a) { case 1: ... break; case 2: ... break; case 3: ... break; case 4: ... break; default: ... break; } Which one is faster? I'm asking ,because my program has a similiar structure(many,many "else if" statements). Should I turn them into switches?

  • SQL Server 15MM rows, simple COUNT query. 15+ seconds?

    - by john
    We took over a website from another company after a client decided to switch. We have a table that grows by about 25k records a day, and is currently at 15MM records. The table looks something like: id (PK, int, not null) member_id (int, not null) another_id (int, not null) date (datetime, not null) SELECT COUNT(id) FROM tbl can take up to 15 seconds. A simple inner join on 'another_id' takes over 30 seconds. I can't imagine why this is taking so long. Any advice? SQL Server 2005 Express

  • DataSet.GetChanges - Save the updated record in a different table than the source one

    - by John Dev
    I'm doing operation on a dataset containing data from a sql table named Test_1 and then get the updated records using the DataSet.GetChanges(DataRowState.Modified) function. Then i try to save the dataset containing the updated records on a different table than the source one (the table is names Test and has the same structure as Test_1) using the following statement: sqlDataAdapter.Update(changesDataSet,"Test"); I'm getting the following error : Update unable to find TableMapping['Test'] or DataTable 'Test' I'm new to ado.net and don't even know if it"s something possible. Any advice is welcome. Just to provide a bit of context. ETL jobs are importing data in temp table with same structure as the original but with _jobid suffix. Right after a rule engine is doing validation before updating the original table.
