  • sql data source re binding question

    - by Keith
    In my gridview after an insert operation has been done I am filtering the sqldatasource by ID. I am getting an error that the item drop down box selected value is not in the list. To test my theory I created a new sql data source with only the select statement and after the insert operation I am binding it to my grid view and filtering by Id and I get my result. The question Having a second data source is not the solution so is it possible that there is some way to use sqldatasource1? what I tried is sqldatasource.databind() and gridview.databind() on the inserted and inserting metheds in many test cases but still that doesnt work. I dont have any filters applied on the original data source?

  • In SQL find the combination of rows whose sum add up to a specific amount (or amt in other table)

    - by SamH
    Table_1 D_ID Integer Deposit_amt integer Table_2 Total_ID Total_amt integer Is it possible to write a select statement to find all the rows in Table_1 whose Deposit_amt sum to the Total_amt in Table_2. There are multiple rows in both tables. Say the first row in Table_2 has a Total_amt=100. I would want to know that in Table_1 the rows with D_ID 2, 6, 12 summed = 100, the rows D_ID 2, 3, 42 summed = 100, etc. Help appreciated. Let me know if I need to clarify. I am asking this question as someone as part of their job has a list of transactions and a list of totals, she needs to find the possible list of transactions that could have created the total. I agree this sounds dangerous as finding a combination of transactions that sums to a total does not guarantee that they created the total. I wasn't aware it is an np-complete problem.

  • error C2065: 'AfxBeginThread' : undeclared identifier

    - by bdhar
    I have a simple ATL Service in which I have included the following statement. AfxBeginThread(WorkerThread, this, THREAD_PRIORITY_NORMAL, 0, 0); But the compiler complains that error C2065: 'AfxBeginThread' : undeclared identifier But in MSDN i found that AfxBeginThread is found in AFXWIN.H If I include AFXWIN.H, the compiler complains that fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h> What am I missing here? Thanks. PS: I am using Visual Studio 6.0 Enterprise Edition in Windows XP SP2.

  • How to explain to a developer that adding extra if - else if conditions is not a good way to "improv

    - by Lilit
    Recently I've bumped into the following C++ code: if (a) { f(); } else if (b) { f(); } else if (c) { f(); } Where a, b and c are all different conditions, and they are not very short. I tried to change the code to: if (a || b || c) { f(); } But the author opposed saying that my change will decrease readability of the code. I had two arguments: 1) You should not increase readability by replacing one branching statement with three (though I really doubt that it's possible to make code more readable by using else if instead of ||). 2) It's not the fastest code, and no compiler will optimize this. But my arguments did not convince him. What would you tell a programmer writing such a code? Do you think complex condition is an excuse for using else if instead of OR?

  • SQL query help - merge a value to all rows in a column

    - by Tommy
    I'm trying to migrate a site from a joomla system to a drupal. The problem is that drupal needs filename and sourcepath in the same row, but joomla only has filename. I'm looking for a way to add sourcepath before the filename in all the rows in that column. I'm figuring it's the UPDATE statement that I should use, but I can't figure out how to construct the query. There's a person with a similar problem here, but I don't find the answers in that thread helpful to my problem: http://www.daniweb.com/forums/showth...t+value&page=2 Any suggestions?

  • 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....

  • Single C++/CLI method to wrap many type specific C functions

    - by T33C
    I am wrapping a C library using C++/CLI so that the C library can be used easily from C# in a C#'ish way. Some of the functions in this library are for putting a value into a container. There are no generics in C so there exists a function per type CLIB_SetBool(BOOL value), CLIB_SetInt(int value), CLIB_SetString(char* string) and so on. To make it easier to use from C#, I have created a single Set function which takes a System::Object. I have two related questions: With my method how would you use a switch statement on the type of System::Object to call the correct CLIB_Setxxxx function. [typeid is only for unmanaged code and I can't seem to use GetType.] Is there a better way to wrap these functions like using a Generic? [I started using template specialisation but then realised that C# doesn't see templates.] Thanks.

  • strange behavior while including a class in php

    - by user1864539
    I'm experiencing a strange behavior with PHP. Basically I want to require a class within a PHP script. I know it is straight forward and I did it before but when I do so, it change the behavior of my jquery (1.8.3) ajax response. I'm running a wamp setup and my PHP version is 5.4.6. Here is a sample as for my index.html head (omitting the jquery js include) <script> $(document).ready(function(){ $('#submit').click(function(){ var action = $('#form').attr('action'); var form_data = { fname: $('#fname').val(), lname: $('#lname').val(), phone: $('#phone').val(), email: $('#email').val(), is_ajax: 1 }; $.ajax({ type: $('#form').attr('method'), url: action, data: form_data, success: function(response){ switch(response){ case 'ok': var msg = 'data saved'; break; case 'ko': var msg = 'Oops something wrong happen'; break; default: var msg = 'misc:<br/>'+response; break; } $('#message').html(msg); } }); return false; }); }); </script> body <div id="message"></div> <form id="form" action="handler.php" method="post"> <p> <input type="text" name="fname" id="fname" placeholder="fname"> <input type="text" name="lname" id="lname" placeholder="lname"> </p> <p> <input type="text" name="phone" id="phone" placeholder="phone"> <input type="text" name="email" id="email" placeholder="email"> </p> <input type="submit" name="submit" value="submit" id="submit"> </form> And as for the handler.php file: <?php require('class/Container.php'); $filename = 'xml/memory.xml'; $is_ajax = $_REQUEST['is_ajax']; if(isset($is_ajax) && $is_ajax){ $fname = $_REQUEST['fname']; $lname = $_REQUEST['lname']; $phone = $_REQUEST['phone']; $email = $_REQUEST['email']; $obj = new Container; $obj->insertData('fname',$fname); $obj->insertData('lname',$lname); $obj->insertData('phone',$phone); $obj->insertData('email',$email); $tmp = $obj->give(); $result = $tmp['_obj']; /* Push data inside array */ $array = array(); foreach($result as $key => $value){ array_push($array,$key,$value); } $xml = simplexml_load_file($filename); // check if there is any data in if(count($xml->elements->data) == 0){ // if not, create the structure $xml->elements->addChild('data',''); } // proceed now that we do have the structure if(count($xml->elements->data) == 1){ foreach($result as $key => $value){ $xml->elements->data->addChild($key,$value); } $xml->saveXML($filename); echo 'ok'; }else{ echo 'ko'; } } ? The Container class: <?php class Container{ private $_obj; public function __construct(){ $this->_obj = array(); } public function addData($data = array()){ if(!empty($data)){ $oldData = $this->_obj; $data = array_merge($oldData,$data); $this->_obj = $data; } } public function removeData($key){ if(!empty($key)){ $oldData = $this->_obj; unset($oldData[$key]); $this->_obj = $oldData; } } public function outputData(){ return $this->_obj; } public function give(){ return get_object_vars($this); } public function insertData($key,$value){ $this->_obj[$key] = $value; } } ? The strange thing is that my result always fall under the default switch statement and the ajax response fit both present statement. I noticed then if I just paste the Container class on the top of the handler.php file, everything works properly but it kind of defeat what I try to achieve. I tried different way to include the Container class but it seem to be than the issue is specific to this current scenario. I'm still learning PHP and my guess is that I'm missing something really basic. I also search on stackoverflow regarding the issue I'm experiencing as well as PHP.net, without success. Regards,

  • Joining two select queries and ordering results

    - by user1
    Basically I'm just unsure as to why this query is failing to execute: (SELECT replies.reply_post, replies.reply_content, replies.reply_date AS d, members.username FROM (replies) AS a INNER JOIN members ON replies.reply_by = members.id) UNION (SELECT posts.post_id, posts.post_title, posts.post_date AS d, members.username FROM (posts) as b WHERE posts.post_set = 0 INNER JOIN members ON posts.post_by = members.id) ORDER BY d DESC LIMIT 5 I'm getting this error: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'a INNER JOIN members ON replies.re' at line 2 All I'm trying to do is select the 5 most recent rows (dates) from these two tables. I've tried Join, union etc and I've seen numerous queries where people have put another query after the FROM statement and that just makes no logical sense to me as to how that works? Am I safe to say that you can join the same table from two different but joined queries? Or am I taking completely the wrong approach, because frankly I can't seem see how this query is failing despite reading the error message. (The two queries on there own work fine)

  • Please help me understand this PHP script.Noob here

    - by NissGTR
    I'm learning PHP,MySQL and came across this function today function get_director($director_id) { global $db; $query = 'SELECT people_fullname FROM people WHERE people_id = ' . $director_id; $result = mysql_query($query, $db) or die(mysql_error($db)); $row = mysql_fetch_assoc($result); extract($row); return $people_fullname; } I understand what functions are and I've created a few while learning PHP.But this one is a bit more complicated.I can't understand the WHERE people_id = ' . $director_id I'm new to MySQL.I guess the single quote ends the MySQL statement?And then it is concatenated with the argument? Please help me out.

  • How does lock(syncRoot) make sense on a static method?

    - by Rising Star
    The following code is excerpted from the (Windows Identity Foundation SDK) template that MS uses to create a new Security Token Service Web Site. public static CustomSecurityTokenServiceConfiguration Current { get { HttpApplicationState httpAppState = HttpContext.Current.Application; CustomSecurityTokenServiceConfiguration customConfiguration = httpAppState.Get( CustomSecurityTokenServiceConfigurationKey ) as CustomSecurityTokenServiceConfiguration; if ( customConfiguration == null ) { lock ( syncRoot ) { customConfiguration = httpAppState.Get( CustomSecurityTokenServiceConfigurationKey ) as CustomSecurityTokenServiceConfiguration; if ( customConfiguration == null ) { customConfiguration = new CustomSecurityTokenServiceConfiguration(); httpAppState.Add( CustomSecurityTokenServiceConfigurationKey, customConfiguration ); } } } return customConfiguration; } } I'm relatively new to multi-threaded programming. I assume that the reason for the lock statement is to make this code thread-safe in the event that two web requests arrive at the web site at the same time. However, I would have thought that using lock (syncRoot) would not make sense because syncRoot refers to the current instance that this method is operating on... but this is a static method? How does this make sense?

  • Any valid use of goto in PHP?

    - by nikic
    I know, there are other questions about the goto statement introduced in PHP 5.3. But I couldn't find any decent answer in there, all were of the type "last resort", "xkcd", "evil", "bad", "EVIL!!!". But no valid example. Only statements that there aren't any uses. Or statements that there are some rare use cases (again, without examples). So, the question is: "Which are the valid uses of goto in PHP". Answers for "Is goto evil" are not welcome and will get downvoted. Thanks :) Or does somebody have a link to an RFC where the decision is explained - I couldn't find one.

  • Will I have legal issues if I attach this 'free' font using @font-face?

    - by janoChen
    *(I'm not sure if StackOverflow is the best place to ask this. But previously, I asked a similar question and it was well received).* I just found this awesome free font (Aller). It is free but it has the following written in the license file: Use by more than 25 Users, or equivalent Website Visitors, is a breach of this Free Licence Agreement, and instead requires a commercial licence. This is what I understand: If it is used in a company with more than 25 employees then it requires commercial license? If the website gets more than 25 visits per month it requires commercial license? Not sure if I got it wrong, but it doesn't make too much sense to me (specially the second statement. I want to use it in my personal portfolio were I provide web design services. Do I need a commercial license?

  • 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.

  • Insert consecutive numbers

    - by Markus
    Hi. I have a table A (Acons, A1, A2, A3) in which I should insert information from another table B with columns (B1, B2, B3). The Acons is a column in which should contain some consecutive numbers (it is not an identity and I cannot make it identity). I know xmin - starting the from number the sequence has to be computed. How can I insert the rows into the table A, using a single Insert statement? I tried like the following, but it didn't work: DECLARE @i AS INT; SET @i = xmin; INSERT INTO A(Acons, A1, A2, A3) SELECT @i = (Bcons = (@i + 1)), B1, B2, B3 FROM B Unfortunatelly, the above solution does not work;

  • 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?

  • 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

  • Anyway to get a value similar to @@ROWCOUNT when TOP is used?

    - by cfeduke
    If I have a SQL statement such as: SELECT TOP 5 * FROM Person WHERE Name LIKE 'Sm%' ORDER BY ID DESC PRINT @@ROWCOUNT -- shows '5' Is there anyway to get a value like @@ROWCOUNT that is the actual count of all of the rows that match the query without re-issuing the query again sans the TOP 5? The actual problem is a much more complex and intensive query that performs beautifully since we can use TOP n or SET ROWCOUNT n but then we cannot get a total count which is required to display paging information in the UI correctly. Presently we have to re-issue the query with a @Count = COUNT(ID) instead of *.

  • Generating Fibonacci series in F#

    - by photo_tom
    I'm just starting to learn F# using VS2010 and below is my first attempt at generating the Fibonacci series. What I'm trying to do is to build a list of all numbers less than 400. let fabList = let l = [1;2;] let mutable a = 1 let mutable b = 2 while l.Tail < 400 do let c = a + b l.Add(c) let a = b let b = c My first problem is that on the last statement, I'm getting an error message "Incomplete structured construct at or before this point in expression" on the last line. I don't understand what I'm doing wrong here. While this seems to be an obvious way to build the list in a fairly efficient way (from a c++/C# programmer), from what little I know of f#, this doesn't seem to feel to be the right way to do the program. Am I correct in this feeling?

  • 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.
