  • VS2010 final does only link project on "rebuild all", not on "build changed"

    - by Sam
    I've just migrated a solution containing c++ and c# projects from VS2008 to VS2010 and got a strange problem. When I select "rebuild all", everything compiles and links as I would expect it to do. Then I change some c++ source file (just add a space), build the project, I get several thousands of linking errors like these: GDlgPackerListe.obj : error LNK2028: Nicht aufgelöstes Token (0A0000C7) ""public: bool __thiscall LList::Add(class LBString const &)" (?Add@LList@@$$FQAE_NABVLBString@@@Z)", auf das in Funktion ""public: virtual void __thiscall LRcPackerListe::HookRunReport(class LFortschritt &)" (?HookRunReport@LRcPackerListe@@$$FUAEXAAVLFortschritt@@@Z)" verwiesen wird.

When I hit "rebuild all" it recompiles and links without any errors or even warnings and produces a working exe. I'm using Visual Studio 2010 final (german edition). Whats going on here? Or, more important: how do I get the linker to work correctly??

  • creating new instance fails PHP

    - by as3isolib
    I am relatively new to PHP and having some decent success however I am running into this issue: If I try to create a new instance of the class GenericEntryVO, I get a 500 error with little to no helpful error information. However, if I use a generic object as the result, I get no errors. I'd like to be able to cast this object as a GenericEntryVO as I am using AMFPHP to communicate serialize data with a Flex client. I've read a few different ways to create constructors in PHP but the typical 'public function Foo()' for a class Foo was recommended for PHP 5.4.4 //in my EntryService.php class public function getEntryByID($id) { $link = mysqli_connect("localhost", "root", "root", "BabyTrackingAppDB"); if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT * FROM Entries WHERE id = '$id' LIMIT 1"; if ($result = mysqli_query($link, $query)) { // $entry = new GenericEntryVO(); this is where the problem lies! while ($row = mysqli_fetch_row($result)) { $entry->id = $row[0]; $entry->entryType = $row[1]; $entry->title = $row[2]; $entry->description = $row[3]; $entry->value = $row[4]; $entry->created = $row[5]; $entry->updated = $row[6]; } } mysqli_free_result($result); mysqli_close($link); return $entry; } //my GenericEntryVO.php class <?php class GenericEntryVO { public function __construct() { } public $id; public $title; public $entryType; public $description; public $value; public $created; public $updated; // public $properties; } ?>

  • Is this text wrapping technique possible in CSS and jQuery?

    - by alex
    I have built a sliding text thing for a website. http://www.solomonadventures.com/~new/adventure-tours/seafari-tours/ The background contains the menu (on the right hand side), and when it originally loads, I have placed an element to make the text look like it is wrapping around the menu. Now, I have a sliding text thing I was asked to implement. The buttons to use it are currently in the top left corner. My question is, when I slide the content down, am I able to somehow make the text still wrap around it? This is all I have thought of so far (all with trade offs) Make the text appear beneath the menu - no need to wrap Make the text as narrow to the beginning of the menu - no need to wrap Manually place placeholders in the text that make it line break so it appears to wrap - not elegant (site uses a CMS too) Is there any jQuery selector I could write that would allow me to select the paragraph from top (once slid to the top) or the top most text node (so I could do an after() to place a new placeholder element to force it to wrap?) Any other solutions? Many thanks.

  • Programmatically create properties - Out of a database table

    - by Kosta
    I already googled around to find a solution for my need, with no success. Let's say I've a table that looks like this: ID |KeyId |Name |Description 1 |153 |Currency |XXXXXXXX 2 |68 |Signature |YYYYYYYY 3 |983 |Contact |ZZZZZZZZ . Now I want to access theses values not by a collection, because I cannot remember all the values, let's say for the name. So this is not what I want: Values.Where(v = v.Name == "Currency").Select(v = v.KeyId); The table content changes rarely but still it is not a nice solution having a struct with all "Names" and getting the KeyId like this. struct Values { public static int Currency { get { return GetKeyId("Currency"); } } } I'm looking for a solution that creates me automatically properties out of this table. So that I can access the KeyId with intellisense. As you have for Resources in ASP.NET. There the class is automatically updated as soon as you add a new entry in the RESX file. For example: Values.Currency , this gives me back the corresponding KeyId. Thanks for reply

  • In MySql Stored Procedure updating more than one time

    - by Both FM
    In MySql UPDATE `inventoryentry` SET `Status` = 1 WHERE `InventoryID`=92 AND `ItemID`=28; It successfully update only one row , where inventoryID = 92 and itemID=28 , the following message displayed. 1 row(s) affected when I put this on stored procedure, as follow CREATE DEFINER=`root`@`localhost` PROCEDURE `Sample`(IN itemId INT, IN itemQnty DOUBLE, IN invID INT) BEGIN DECLARE crntQnty DOUBLE; DECLARE nwQnty DOUBLE; SET crntQnty=(SELECT `QuantityOnHand` FROM `item` WHERE id=itemId); SET nwQnty=itemQnty+crntQnty; UPDATE `item` SET `QuantityOnHand`=nwQnty WHERE `Id`=itemId; UPDATE `inventoryentry` SET `Status` = 1 WHERE `InventoryID`=invID AND `ItemID`=itemId; END$$ calling stored procedures CALL Sample(28,10,92) It update all the status = 1 in inventoryentry against InventoryID (i.e. 92) ignoring ItemID, instead of updating only one row. The following message displayed! 5 row(s) affected Why Stored procedure ignoring itemID in update statement ? or Why Stored procedure updating more than one time? But without Stored procedure it working fine.

  • How to make a Stored Procedure that takes in XML and uses that xml as an Update + call this stored p

    - by chobo2
    Hi I am using ms sql server 2005 and I want to do a mass update. I am thinking that I might be able to do it with sending an xml document to a stored procedure. So I seen many examples on how to do it for insert CREATE PROCEDURE [dbo].[spTEST_InsertXMLTEST_TEST](@UpdatedProdData XML) AS INSERT INTO dbo.UserTable(CreateDate) SELECT @UpdatedProdData.value('(/ArrayOfUserTable/UserTable/CreateDate)[1]', 'DATETIME') But I am not sure how it would look like for an update. I am also unsure how do I pass in the xml through ado.net? Do I pass it as a string through a parameter or what? I know sqlDataApater has a batch update method but I am using linq to sql. So I rather keep using it. So if this works I would be able to grab all records with linq to sql and have them as objects. Then manipulate the objects and use xml seralization. Finally I could just use ado.net simple to send the xml to the server. This might be slower then the sqlDataAdapter but I am willing to take that hit if I can keep using objects.

  • Is it possible to install into Program Files with limited privileges?

    - by Marek
    I have an application that will be deployed as MSI package (authored in WiX). I am deciding whether to specify elevated or limited privileges as required for the installer. The application does not include anything requiring elevated privileges besides the default install location, which is under Program Files. Now the problem: If I specify elevated privileges, then the user is prompted by UAC for administrator password during the installation. This is not required and prevents non-admin users from installing. If I specify limited privileges, then the user is presented with a dialog to select install location with Program Files being default. In case they do not change the install location (95 % of end users probably won't), then the installer will fail with a message that they should contact the Administrator or run the application as administrator. If they launch the installer as Administrator then they can install into Program Files without problem - but most of the users won't probably know how to launch an installer as administrator. I can potentially set the default install location to e.g. C:\Company name\Program\, but this seems nonstandard to me and majority of users will not probably like this (they are probably used to installing into Program Files). How do you solve this problem with installing applications under limited user accounts?

  • MySQL query against pseudo-key-value pair data in WordPress custom query

    - by andrevr
    I'm writing a custom WordPress query to use some of the data which the Woothemes Diarise theme creates. Diarise is an event planner theme with calendar blah, blah... and uses custom fields to store the event start and end dates in WP custom fields in the *wp_postmeta* table, which implements a key-value store. So for each post in the "event" category, there are 2 records in *wp_postmeta*, named *event_start_date* and *event_end_date* that I'm interested in. The task is to compare a tourist's arrival and departure dates with the start and end dates of events, yielding a what's on list of events available. We thought we'd killed it with a grand flash of logic, that goes like this: Disregard any event that ends before the tourist arrives, and any that begin after the departure date. I wrote this query: SELECT wposts.* FROM wp_posts wposts LEFT JOIN wp_postmeta wpostmeta ON wposts.ID = wpostmeta.post_id LEFT JOIN wp_term_relationships ON (wposts.ID = wp_term_relationships.object_id) LEFT JOIN wp_term_taxonomy ON (wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id) WHERE wp_term_taxonomy.taxonomy = 'category' AND wp_term_taxonomy.term_id IN(3,4) AND ( wpostmeta.meta_key = 'event_start_date' AND NOT ( concat(subst(wpostmeta.meta_value,7,4),'-',subst(wpostmeta.meta_value,4,2),'-',subst(wpostmeta.meta_value,1,2) > '2010-07-31' ) ) AND ( wpostmeta.meta_key = 'event_end_date' AND NOT ( concat(subst(wpostmeta.meta_value,7,4),'-',subst(wpostmeta.meta_value,4,2),'-',subst(wpostmeta.meta_value,1,2) < '2010-05-01' ) ) ) ORDER BY wpostmeta.meta_value ASC And, of course it returns no records. The problem I believe is in the dual reference to wpostmeta.meta_key, but how to get around that?

  • node.js: looping, email each matching row from query but it it emails the same user by # number of matches?

    - by udonsoup16
    I have a node.js email server that works fine however I noticed a problem. If the query string found 4 rows, it would send four emails but only to the first result instead of to each found email address. var querystring1 = 'SELECT `date_created`,`first_name`,`last_name`,`email` FROM `users` WHERE TIMESTAMPDIFF(SECOND,date_created, NOW()) <=298 AND `email`!="" LIMIT 0,5'; connection.query(querystring1, function (err, row) { if (err) throw err; for (var i in row) { // Email content; change text to html to have html emails. row[i].column name will pull relevant database info var sendit = { to: row[i].email, from: '******@******', subject: 'Hi ' + row[i].first_name + ', Thanks for joining ******!', html: {path:__dirname + '/templates/welcome.html'} }; // Send emails transporter.sendMail(sendit,function(error,response){ if (error) { console.log(error); }else{ console.log("Message sent1: " + row[i].first_name);} transporter.close();} ) }}); .... How do I have it loop through each found row and send a custom email using row data individual row data?

  • Can one connection get details of another? Or, how can I get the most detailed pending transaction

    - by bob-the-destroyer
    Is there a Mysql statement which provides full details of any other open connection or user? For this particular case, on myisam tables specifically. Looking at Mysql's SHOW TABLE STATUS documentation, it's missing some very important information for my purpose. For example: remote odbc connection one is inserting several thousand records, which due to a slow connection speed can take up to an hour. Tcp connection two, using PHP on the server's localhost, is running select queries with aggregate functions on that data. Before allowing connection two to run those queries, I'd like connection two to first check to make sure there's no pending inserts on any other connection on those specific tables so it can instead wait until all data is available. If the table is currently being written to, I'd like to spit back to the user of connection two an approximation of how much longer to wait based on the number of pending inserts. Ideally by table, I'd like to get back using a query the timestamp when connection one began the write, total inserts left to be done, and total inserts already completed. Instead of insert counts, even knowing number of bytes written and left to write would work just fine here. Obviously since connection two is a tcp connection via a PHP script, all I can really use in that script is some sort of query. I suppose if I have to, since it is on localhost, I can exec() it if the only way is by a mysql command line option that outputs this info, but I'd rather not. I suppose I could simply update a custom-made transaction log before and after this massive insert task which the PHP script can check, but hopefully there's already a built-in Mysql feature I can take advantage of.

  • T-SQL: Dynamic Query by Selected Column in ASP.NET GridView

    - by jp2code
    I'm trying to modify a stored procedure used in an ASP.NET page. By default, the stored procedure returns all of the data, which can be overwhelming for employees in the plant. I want to add a drop down menu item for the column name and a text box for a value to allow our employees to search the data for their specific items. What I would like to add is the ability to pass in a Column Name and Column Value to search, similar to the following: DECLARE @colName nVarChar(50), @colValue nVarChar(50) SET @colName='EmployeeID' SET @colValue='007135' SELECT Column1, Column2, Column3, Column4, Column5, Column6, Column7 FROM viewNum1 WHERE ((@colName IS NULL) OR (@colValue IS NULL) OR ('['+@colName+']'=@colValue)) If all values passed in (@colValue and @colName), all records return; however, if I try specifying that @colName=EmployeeID and @colValue='007135' (a value that does exist in the database), no records are returned. Next is the problem that I am running an old SQL Server 2000 database that does not allow the stored procedure to access the table column names, and the whole technique looks prone to SQL Injection. Finally, I don't see how to bind my GridView control to this and still have the ability to display all records. How would I write such a filtering stored procedure?

  • Linq to xml, retreaving generic interface-based list

    - by Rita
    I have an xml document that looks like this <Elements> <Element> <DisplayName /> <Type /> </Element> </Elements> I have an interface, interface IElement { string DisplayName {get;} } and a couple of derived classes: public class AElement: IElement public class BElement: IElement What I want to do, is to write the most efficient query to iterate through the xml and create a list of IElement, containing AElement or BElement, based on the 'Type' property in the xml. So far I have this: IEnumerable<AElement> elements = from xmlElement in XElement.Load(path).Elements("Element") where xmlElement.Element("type").Value == "AElement" select new AElement(xmlElement.Element("DisplayName").Value); return elements.Cast<IElement>().ToList(); But this is only for AElement, is there a way to add BElement in the same query, and also make it generic IEnumerable? Or would I have to run this query once for each derived type?

  • Playframework sends 2 queries for fetched query

    - by MRu
    I currently have problems with the JPA at the play framework 1.2.4. I need to have a UserOptions model in a separate database and want to join it lazyly cause its only needed in one query. In this query I want to load the options eagerly and by searching I found out that can only be done by using a join query. If I use eager instead oder lazy, everything would be fine by using User.findById() and the options and the user is found in one query. But play sends two queries when I use a 'left join fetch' query. So heres the query: User.find(" SELECT user FROM User user LEFT JOIN FETCH user.options options WHERE user.id = ? ", Long.parseLong(id)).first(); And here the models: @Entity public class User extends Model { @OneToOne(mappedBy = "user", fetch = FetchType.LAZY) public UserOptions options; // ... } @Entity public class UserOptions extends Model { @OneToOne(fetch = FetchType.LAZY) public User user; } The question is why play sends two query for the fetch query? Thanks in advance

  • How is this Perl code selecting two different elements from an array?

    - by Mike
    I have inherited some code from a guy whose favorite past time was to shorten every line to its absolute minimum (and sometimes only to make it look cool). His code is hard to understand but I managed to understand (and rewrite) most of it. Now I have stumbled on a piece of code which, no matter how hard I try, I cannot understand. my @heads = grep {s/\.txt$//} OSA::Fast::IO::Ls->ls($SysKey,'fo','osr/tiparlo',qr{^\d+\.txt$}) || (); my @selected_heads = (); for my $i (0..1) { $selected_heads[$i] = int rand scalar @heads; for my $j (0..@heads-1) { last if (!grep $j eq $_, @selected_heads[0..$i-1]); $selected_heads[$i] = ($selected_heads[$i] + 1) % @heads; #WTF? } my $head_nr = sprintf "%04d", $i; OSA::Fast::IO::Cp->cp($SysKey,'',"osr/tiparlo/$heads[$selected_heads[$i]].txt","$recdir/heads/$head_nr.txt"); OSA::Fast::IO::Cp->cp($SysKey,'',"osr/tiparlo/$heads[$selected_heads[$i]].cache","$recdir/heads/$head_nr.cache"); } From what I can understand, this is supposed to be some kind of randomizer, but I never saw a more complex way to achieve randomness. Or are my assumptions wrong? At least, that's what this code is supposed to do. Select 2 random files and copy them. === NOTES === The OSA Framework is a Framework of our own. They are named after their UNIX counterparts and do some basic testing so that the application does not need to bother with that.

  • Unobstrusive pseudo-classes and attribute selectors emulation in IE

    - by Álvaro G. Vicario
    I'm trying to emulate some pseudo-classes and attribute selectors in Internet Explorer 6 and 7, such as :focus, :hover or [type=text]. So far, I've managed to add a class name to the affected elements: $("input, textarea, select") .hover(function(){ $(this).addClass("hover"); }, function(){ $(this).removeClass("hover"); }) .focus(function(){ $(this).addClass("focus"); }) .blur(function(){ $(this).removeClass("focus"); }); $("input[type=text]").each(function(){ $(this).addClass("text"); }); However, I'm still forced to duplicate selector in my style sheets: textarea:focus, textarea.focus{ } And, to make things worse, IE6 seems to ignore all the selectors when it finds an attribute: input[type=text], input.text{ /* IE6 ignores this */ } And, of course, IE6 ignores selectors with multiple classes: input.text.focus{ /* IE6 ignores this */ } So I'm likely to end up with this mess: input[type=text]{ /* Rules here */ } input.text{ /* Same rules again */ } input[type=text]:focus{ } input.text_and_focus{ } input.text_and_hover{ } input.text_and_focus_and_hover{ } My question: is there any way to read the rules or computed style defined for a CSS selector and apply it to certain elements, so I only need to maintain one set of standard CSS?

  • Best method to search hierarchical data

    - by WDuffy
    I'm looking at building a facility which allows querying for data with hierarchical filtering. I have a few ideas how I'm going to go about it but was wondering if there are any recommendations or suggestions that might be more efficient. As an example imagine that a user is searching for a job. The job areas would be as follows. 1: Scotland 2: --- West Central 3: ------ Glasgow 4: ------ Etc 5: --- North East 6: ------ Ayrshire 7: ------ Etc A user can search specific (i.e. Glasgow) or in a larger area (i.e. Scotland). The two approaches I am considering are: keep a note of children in the database for each record (i.e. cat 1 would have 2, 3, 4 in its children field) and query against that record with a SELECT * FROM Jobs WHERE Category IN Areas.childrenField. Use a recursive function to find all results who have a relation to the selected area. The problems I see from both are: Holding this data in the db will mean having to keep track of all changes to structure. Recursion is slow and inefficent. Any ideas, suggestion or recommendations on the best approach? I'm using C# ASP.NET with MSSQL 2005 DB.

    - by jpavlov
    I am working at gaining an understanding at how to interface stored procedures with applications. My example is simple, but it doesn't display my columns and rows in the command prompt, instead it display System.Data.SqlClient.SqlDataReader. How do I display the rows from my stored procudure? ----Stored Proc-- ALTER PROCEDURE dbo.SelectID AS SELECT * FROM tb_User; ----- Below is the code: using System; using System.Data.SqlClient; using System.IO; namespace ExecuteStoredProc { class Program { static void Main(string[] args) { SqlConnection cnnUserMan; SqlCommand cmmUser; //SqlDataReader drdUser; //Instantiate and open the connection cnnUserMan = new SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename=c:\\Program Files\\Microsoft SQL Server\\MSSQL10.SQLEXPRESS\\MSSQL\\DATA\\UserDB.mdf; Integrated Security=True;Connect Timeout=30;User Instance=True"); cnnUserMan.Open(); //Instantiate and initialize command cmmUser = new SqlCommand("SelectID", cnnUserMan); cmmUser.CommandType = System.Data.CommandType.StoredProcedure; //drdUser = cmmUser.ExecuteReader(); Console.WriteLine(cmmUser.ExecuteReader()); Console.ReadLine(); } } } Thanks.

  • Refining Search Results [PHP/MySQL]

    - by Dae
    I'm creating a set of search panes that allow users to tweak their results set after submitting a query. We pull commonly occurring values in certain fields from the results and display them in order of their popularity - you've all seen this sort of thing on eBay. So, if a lot of rows in our results were created in 2009, we'll be able to click "2009" and see only rows created in that year. What in your opinion is the most efficient way of applying these filters? My working solution was to discard entries from the results that didn't match the extra arguments, like: while($row = mysql_fetch_assoc($query)) { foreach($_GET as $key => $val) { if($val !== $row[$key]) { continue 2; } } // Output... } This method should hopefully only query the database once in effect, as adding filters doesn't change the query - MySQL can cache and reuse one data set. On the downside it makes pagination a bit of a headache. The obvious alternative would be to build any additional criteria into the initial query, something like: $sql = "SELECT * FROM tbl MATCH (title, description) AGAINST ('$search_term')"; foreach($_GET as $key => $var) { $sql .= " AND ".$key." = ".$var; } Are there good reasons to do this instead? Or are there better options altogether? Maybe a temporary table? Any thoughts much appreciated!

  • DELETE causing a redirect loop?

    - by robocode
    I have an express app with a postgres backend where a user can add/delete recipes, and each time they do so they get an updated list of recipes. Adding a recipe is fine, but when I delete one it seems to get stuck in a redirect loop. In app.js I have router.get('/delete/:d', delRec.deleteRecipe); which calls the following code exports.deleteRecipe = function(req, res){ pg.connect(conString, function(err, client) { client.query('DELETE FROM recipes WHERE recipe_name = ', [req.params.d], function(err, result) { if(err) { return console.error('error running query', err); } else if (result) { pg.end(); console.log('deleting'); } }); }); res.redirect('recipes'); }; If I try delete a recipe, console.log('deleting') produces deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting The recipes route is below (sorry that it's so convoluted) router.get('/recipes', function(req, res) { pg.connect(conString, function(err, client) { if(err) { return console.error('could not connect to postgres', err); } client.query('SELECT * FROM recipes', function(err, result) { if(err) { return console.error('error running query', err); } recipes = result.rows; for(var d in recipes) { if (recipes.hasOwnProperty(d)) { recipeList[d] = recipes[d].recipe_name; } } res.render('recipes', {recipes: recipes, recipeList: recipeList}); }); }); });
