• What do C# Table Adapters actually return?

  - by Raven Dreamer

  I'm working on an application that manipulates SQL tables in a windows form application. Up until now, I've only been using the pre-generated Fill queries, and self-made update and delete queries (which return nothing). I am interested in storing the value of a single value from a single column (an 'nchar(15)' name), and though I have easily written the SQL code to return that value to the application, I have no idea what it will be returned as. SELECT [Contact First Name] FROM ContactSkillSet WHERE [Contact ID] = @CurrentID Can the result be stored directly as a string? Do I need to cast it? Invoke a toString method?

• @ symbol for strings in jQuery

  - by anilca

  if (confirm('<%=Ns1.Ns2.MyClass.GetResourceText("DeleteConfirmationMessage")%>')) { /* something to do...*/ } I have a jQuery expression as above. But the return value of GetResourceText method is a very long string. So my page renders the function like below: if (confirm(' Are you sure lablabla? If you delete this lablabla... lablabla... ')) { Because of this my jQuery functions do not work. Is there a symbol for jQuery like @ that we use in C#?

• Two phase Construction in C++

  - by tommieb75

  I have as part of assignment to look into a development kit that uses the "two-phase" construction for C++ classes: // Include Header class someFubar{ public: someFubar(); bool Construction(void); ~someFubar(); private: fooObject _fooObj; } In the source // someFubar.cpp someFubar::someFubar : _fooObj(null){ } bool someFubar::Construction(void){ bool rv = false; this->_fooObj = new fooObject(); if (this->_fooObj != null) rv = true; return rv; } someFubar::~someFubar(){ if (this->_fooObj != null) delete this->_fooObj; } Why would this "two-phase" be used and what benefits are there? Why not just instantiate the object initialization within the actual constructor?

• Application Role and access second database

  - by lszk

  I have written a script to create an audit trails to my database in a second one db. So far I had no problems during tests on my dev machine from SQL Server Management Studio. Problems started to occurs when I first tried to test my triggers from my application by modyfing data in it. Using profiler I found out, that my audit trails db is not visible in sys.databases, so here lies the problem. The application using an Application Role, so as I found on MSDN, that's why I can't get access to other db on the server. I'm not a DBA. I have no experience with properly settings the security stuff, so please guide me, how can I set the setting for guest account (according to MSDN) to get access to this db? I need to have a record for this database in sys.databases and I need to be able to insert data in this database in all tables. No select, update or delete I need.

• Visual Studio adds a circular reference when I drag and drop a user control from the Toolbox

  - by JoelFan

  I have a user control C that is defined inside project P. C is present as a ".NET Framework Component" in my Visual Studio Toolbox. I open a form F (also defined inside project P) and drop C onto F. Once I do that drop, Visual Studio adds a reference under P pointing to P's own DLL. This is unnecessary and causes tons of build errors like The call is ambiguous between the following methods or properties... after which it lists the exact same method twice. If I go into References and delete the added reference, it builds correctly. Can I prevent VS from adding this unnecessary reference?

• Export SQL Binary/BLOB Data?

  - by davemackey

  Recently a software application we utilize upgraded from ASP to ASP.NET. In the process they abandoned the old web-based product and rewrote the entire UI, using new DB tables. The old DB tables still exist in the database and contain legacy files in binary or blob formats. I'm wondering if there is an easy way to export all these legacy files from the database to the filesystem (NTFS)? Then we could delete these old unused tables and save a few GB of space in the DB backups, etc.

• TFS: how to change custom field allowed values

  - by Budda

  I have my custom field of string type with predefined set of values: "1 - Cool", "2 - Good", "3 - Average",... Now it is necessary to remove "2 - Good" value and rename "3 - Average" into "2 - Average". I see easy solution: just delete 2 existing "2 - Good" and "3 - Average" and create the new "2 - Average". Question: Q1: What will happens with issues that contain values to be deleted? Probably, system won't accept such work item change? Q2: What is a good approach to do what I need? Thanks a lot! Any thoughts are welcome!

• 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"; ?>

• Eclipse plugin to measure programmer performance/stats

  - by trenki

  Does anyone know of an Eclipse plugin that can give me some stats about my behavior/usage of the Eclipse IDE? There are quite a few things I would like to know: How often/when do I invoke the "Build All" command (through Ctrl+B) How often does compilation fail/succeed (+ number of errors/warnings) How often do I hit Backspace? (I do that way to often; If pressing that key would give a nasty sound I would in time learn to type correctly in the first place) How many characters/lines of code that I typed do I delete (possibly quite immediately) How (effective/efficient/...) is my Mouse/Keyboard/IDE usage? (Kinda like measuring APM in StarCraft; this could be fun) If there is no such Eclipse plugin around, how complex and time consuming would It be to write a plugin that can accomplish the above?

• Lua not producing table of functions (IO API)

  - by ArtOfCode

  I'm working on a basic project in Lua. I've been trying to get data from files using the IO API (as defined here), but when I open a file and give it a handle, it doesn't seem to return a table of functions. The (erroneous bit of) code: local unread = fs.list("email/"..from.."/") local send = "" for _,file in ipairs(unread) do local handle = io.open(file,"r") local text = handle:read("*a") send = send .. text .. "\n" handle.close() fs.delete(file) end The fs you see on the first line is a professional filesystem wrapper round the IO API, not my work and perfectly error-free, so that's not the problem. However, when I try to read the file (handle:read()), it throws "attempt to index nil". Tracing it, it turns out that handle itself is nil. Any ideas?

• Java ME Runnable object takes up memory although not made an instance yet

  - by user1646684

  I am facing a strange problem with memory in Java ME. here is a part of my code: int variable=1; while (true) { if (variable==2) { display = Display.getDisplay(this); MyCanvas mc = new MyCanvas(this); // MyCanvas is a runnable object mcT = new Thread(mc); // new thread for MyCanvas mc.repaint(); display.setCurrent(mc); mcT.start(); // run thread } if (variable==1) { // Do some other stuff } } The problem is that although still the variable is set to 1, so it does not come through the if (variable==2) condition the program consumes 300kB more memory than when I delete the code after condition if (variable==2). As far as I know the code should by executed and the objects shall be created only when I set variable to value 2. But it consumes the memory also when the code after condition "if (variable==2)" is not executed. Why does this happen?

• Displaying Data from a Join in Codeigniter

  - by Brad

  I am using a simple join to pull data from two databases. This is the join in the model function com_control(){ $this->db->select('*'); $this->db->from('comments'); $this->db->join('posts', 'comments.entry_id = posts.id'); $query = $this->db->get(); return $query->result; } My desired method of display is going to be in a table so I am starting out to use like this foreach($comm_control as $row){ $this->table->add_row( $row->entry_id, $row->comments.id, $row->comment, $row->title ); }//end of foreach My problem is the display of data from comments.id. What is the proper format to add the comment.id into the table rows? I need the ID from both tables for display, edit and delete further on in the table. The only display I get at this time for "comment.id" is the word id. The Any help would be appreciated.

• Design cache mechanism

  - by Delashmate

  Hi All, I got assignment to write design for cache mechanism, This is my first time writing a design document, Our program display images for doctors, and we wan't to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

• Is there any difference in the implementation of these three validation methods?

  - by dontWatchMyProfile

  Core Data is calling these methods in certain situations: - (BOOL)validateForInsert:(NSError **)outError; - (BOOL)validateForUpdate:(NSError **)outError; - (BOOL)validateForDelete:(NSError **)outError; I wonder if they're doing anything different, or if they're essentially doing the exact same things. As far as I know, these methods call the -validateValue:forKey:error: method once for every property. The only difference I can imagine is in the .validateForDelete: method. I see no reason why to validate an object when it shall be deleted, except for applying delete rules, probably only in the case of the DENY rule.

• How do I return an object that is able to execute on the server?

  - by mafutrct

  Coming from a Java background, this is the way I'm thinking: The server provides an object to the client. This object should be able to execute on the server. Server: private string _S = "A"; public interface IFoo { void Bar(); } private class Foo : IFoo { void Bar() { _S = "B";} } public IFoo GetFoo() { return new Foo(); } Client: IFoo foo = serverChannel.GetFoo(); foo.Bar(); Remoting is legacy (everyone keeps pointing to WCF instead) and WCF does not support this at all basically ( http://stackoverflow.com/questions/2431510 ), so how should I implement this kind of behavior? Using 3rd party components is possible iff required. I searched on SO but found no similar question. If this has indeed been answered before, just let me know and I'll delete.

• Problem with Nulls and an UPDATE statement

  - by Dave

  UPDATE TableA SET Value = a.Value * b.AnotherValue FROM TableA AS a INNER JOIN TableB AS b WHERE (Condition is true); Here is the problem. The Value field for TableA does not allow nulls. If the calculation of a.Value * b.AnotherValue yields a null, an error is thrown. Now the question. Is there any way to tell the UPDATE to ignore the SET phase when the result of the calculation is a null and delete the record rather than updating it. This UPDATE is intended to update hundreds of records at a time but will fail if a single null is encountered. Also, please note that using the ISNULL() function and setting the Value to zero is not acceptable. I would like the record to be dropped if a null is encountered. Many thanks in advance for any help rendered.

• Where does Eclipse save the list of files to open on startup?

  - by Grundlefleck

  Question: where does Eclipse store the list of files it opens on startup? Background: Having installed a plugin into Eclipse which promptly crashed, my Eclipse workspace is in a bit of a state. When started, the building workspace task pauses indefinitely at 20%. Before I uninstall the plugin I want to give it another chance. I have a feeling that the reason Eclipse is pausing is because of a file which was opened when it crashed, which it tries to reopen on startup. If I can stop this file from opening on startup there's a chance I may be able to coax the plugin to behave. The problem is I have no idea where that list of files is persisted between runs of Eclipse. ...a second before I posted this question, I realised I could just delete the file causing the problem (duh). However, the search has frustrated me enough to want to find the answer.

• How to insert the recently inserteddata of a table to others DB's Table? See description...

  - by Parth

  I am using MySQL DB and I have created a PHP script for the following, now i need the idea for the below asked question.... please help... I have a table called audit trail whose structure is: id, trackid, table, operation, newvalue, oldvalue, field, changedone I have created triggers for insert/update/delete for every table of same DB, now whenever there is change in ny DB the triggers get activated and updates the Audit trail table accordingly.. I am tracking these changes so that i can use these changes to be done on production DB which is of same structure as of this test DB. Also when the admin finds that he does not need the changes recently he did for production DB then he can rollback it using the Old Data it stored in Ausittrail table of test db. Now here in audit trail table structure, there will be an insert for every single field change like-wise if a table has 4 fields then the change in that tavle will insert 4 rows in audit trail.. Coming to the question now, How can i find the latest change done from the Audit table so that I can insert these changes in Production DB.

• C#, Manage concurrency in database access

  - by Goul

  Hi there, I have written a while ago an application used by multiple users to handle trades creation. I haven't done development for some time now and can't remember how I managed the concurrency between the users and so would have liked your advices in term of design. The application was as follow: - One heavy client per user - A single database - Access to the database for each user to insert/update/delete trades - A grid in the application reflecting the trades table. That grid being updated each time someone changes a deal. My questions: 1- Do you confirm I shouldn't care about the connection to the database for each application. Considering that there is a singleton in each, I would expect on connexion per client with no issue. 2- How preventing the concurrency of the accesses? I guess I should lock when modifying the data, however don't remember how to. 3- How to have the grid automatically updated whenever the database is (by another user for example)? Thank you in advance for your help!

• g++ library search failure

  - by Frederick

  I have a directory structure as below: / | +--- /lib | libsomething.a | libsomething.so | +----/obj anObjFile.o When I run the following command from within the obj directory: g++ -L../lib -lsomething anObjFile.o I get undefined reference errors. Apparently gcc is failing to locate libsomething.a. But now if I delete libsomething.so and then rerun the command, linking succeeds. As per gcc documentation -lsomething should expand to libsomething.a. Then why is presence of libsomething.so causing the library search to fail? Also, how can I resolve this problem? I'm on Linux Mint 12 with gcc version 4.6.1.

• How to make a staging table in ms sql 2005?

  - by chobo2

  Hi I heard about doing staging tables and I am wondering how you actually do it. I want to do a sqlbulk copy into a staging table. Then then update the real table. I heard in mssql 2008 that you can use something called merge but I am using ms sql 2005 so I heard I have to use a update inner join? I am not sure how that would look like(I am guessing best way would be to write it in SP). Also the staging table needs to be able to handle concurrent updates. I was thinking of putting another column in the staged as GUID so that way I know which records belong to which group and when it is time to delete the records from the staged table I can just use that. So can anyone show me any examples or tutorials on how to do it? Also how fast is this way? Say if your updating 50,000 records how long would that take(a guesstimate is fine)

• How come $(this) is undefined after ajax call

  - by JohnnyQ

  I am doing an ajax request when an anchor tag is clicked with an ID set to href. Btw, this anchor tag is dynamically created. <a href="983" class="commentDeleteLink">delete</a> When the anchor tag is clicked the following code is executed: $('.commentDeleteLink').live('click', function(event) { event.preventDefault(); var result = confirm('Proceed?'); if ( result ) { $.ajax({ url: window.config.AJAX_REQUEST, type: "POST", data: { action : 'DELCOMMENT', comment : $('#commentText').val(), comment_id : $(this).attr('href') }, success: function(result) { alert($(this).attr('href')); //$(this).fadeOut(slow); } }); } }); When I tried to display $(this).attr('href') it says it's "undefined". What I really want to do is fadeOut the anchor tag but when I investigated the value of $(this) it is "undefined". What could be wrong with the snippet above?

• C++ convert formatted string to a stream

  - by Roey

  Hi All, I'm using VS2008 C++. As I understand it there is no way to pass something like this in a C++ stream : (without using external libraries) "number " << i <------ when i is an integer. So I was looking for a better way to do this, and I all I could come up with is create a string using : char fullstring = new char[10]; sprintf(fullString, "number %d", i); .... pass fullstring to the stream ..... delete[] fullString; I know it's stupid, but is there a better way of doing this?
