• Compiling 32-bit Program on VS 2008

  - by gordonwd

  I've been developing on VC++ 2003 on an XP PC but am now on Windows 7 and bought a cheap legal copy of VS 2008 to continue work on the same project. My product has to continue to run on customers' XP systems, so I'm strictly interested in a 32-bit executable. The first issue I ran into was the PRJ0003 error "spawning cl.exe". I had to add the path to this file to the VC++ Directories settings (it appears in both a bin\amd64 and bin\x86_amd64 directory, but I don't think it matters output-wise which I use?). The issue I now have (not counting a tedious cleanup to convert strcpy to strcpy_s, etc.) is that I'm not clear on whether I'm generating a 32-bit or 64-bit exe out of this. My project properties are set to a target of "Win32", so I assume that all is well. Is this correct? I have read some discussions about this, but it's never quite clear if they are talking about whether the compiler itself is running x64 vs. x86, or whether the compiled code is x64 vs. x86, and how this is differentiated. So am I doing the right thing to generate a 32-bit, Win32, x-86 program?

• jQuery $.each()-problem

  - by Volmar

  Hi, im making a wordpress plugin and i have a function where i import images, this is done with a $.each()-loop that calls a .load()-function every iteration. The load-function page the load-function calls is downloading the image and returns a number. The number is imported into a span-element. The source and destination Arrays is being imported from LI-elemnts of a hidden ULs. this way the user sees a counter counting from zero up to the total number of images being imported. You can se my jQuery code below: jQuery(document).ready(function($) { $('#mrc_imp_img').click(function(){ var dstA = []; var srcA = []; $("#mrc_dst li").each(function() { dstA.push($(this).text()) }); $("#mrc_src li").each(function() { srcA.push($(this).text()) }); $.each(srcA, function (i,v) { $('#mrc_imgimport span.fc').load('/wp-content/plugins/myplugin/imp.php?num='+i+'&dst='+dstA[i]+'&src='+srcA[i]); }); }); }); This works pretty good but sometimes it looks like the load function isn't updating the DOM as fast as it should because sometimes the numbers that the span is updated with is lower than the previous and almost everytime a lower number is replacing the last number in the end. How can i prevent this from happening and how can i make it hide '#mrc_imp_img' when the $.each-loop is ready?

• Ordering by number of rows?

  - by Rob

  Alright, so I have a table outputting data from a MySQL table in a while loop. Well one of the columns it outputs isn't stored statically in the table, instead it's the sum of how many times it appears in a different MySQL table. Sorry I'm not sure this is easy to understand. Here's my code: $query="SELECT * FROM list WHERE added='$addedby' ORDER BY time DESC"; $result=mysql_query($query); while($row=mysql_fetch_array($result, MYSQL_ASSOC)){ $loghwid = $row['hwid']; $sql="SELECT * FROM logs WHERE hwid='$loghwid' AND time < now() + interval 1 hour"; $query = mysql_query($sql) OR DIE(mysql_error()); $boots = mysql_num_rows($query); //Display the table } The above is the code displaying the table. As you can see it's grabbing data from two different MySQL tables. However I want to be able to ORDER BY $boots DESC. But as its a counting of a completely different table, I have no idea of how to go about doing that. I would appreciate any help, thank you.

• Grouping by date, with 0 when count() yields no lines

  - by SCO

  I'm using Postgresql 9 and I'm fighting with counting and grouping when no lines are counted. Let's assume the following schema : create table views { date_event timestamp with time zone ; event_id integer; } Let's imagine the following content : 2012-01-01 00:00:05 2 2012-01-01 01:00:05 5 2012-01-01 03:00:05 8 2012-01-01 03:00:15 20 I want to group by hour, and count the number of lines. I wish I could retrieve the following : 2012-01-01 00:00:00 1 2012-01-01 01:00:00 1 2012-01-01 02:00:00 0 2012-01-01 03:00:00 2 2012-01-01 04:00:00 0 2012-01-01 05:00:00 0 . . 2012-01-07 23:00:00 0 I mean that for each time range slot, I count the number of lines in my table whose date correspond, otherwise, I return a line with a count at zero. The following will definitely not work (will yeld only lines with counted lines 0). SELECT extract ( hour from date_event ),count(*) FROM views where date_event > '2012-01-01' and date_event <'2012-01-07' GROUP BY extract ( hour from date_event ); Please note I might also need to group by minute, or by hour, or by day, or by month, or by year (multiple queries is possible of course). I can only use plain old sql, and since my views table can be very big (100M records), I try to keep performance in mind. How can this be achieved ? Thank you !

• I am looking for a svn helper program

  - by uzay95

  I didn't remember the name of this program. But i can remember how it works. Program is working on tray. When we double click on it it is showing its main window. :) I could add some criterias to make automatic commit(and maybe update). For ex: if a file changes or if files to be deleted, you can commit. The best part of this program is: "it is FREE" I don't remember exactly but i think it has M name in its name (but i don't remember). I think this program written by an Italian man. And its web site was very simple (and i think its fonts were green)

• EntityFramework 4.0: can you return different types depending on data in the database?

  - by user200341

  I have a Media table in the database. I also have an IMedia interface. I have two different media types that implements the same interface: 1) AudioMedia 2) PictureMedia What I wonder here, is if I can use EntityFramework (I'm using an EDMX file but I have my models in a separate library, with automatic code generation turned off), and depending on the data in the database, select what type to get (AutioMedia or PictureMedia). Since they are both implementing the same interface (could be changed to an abstract class if needed I suppose), I'm thinking that somewhere along the way you could specify what class it should be. I should perhaps point out that I have a class that inherits from ObjectContext to access the objects. Perhaps there is something that that can be done?

• Proper chart scaling in Reporting Services 2005

  - by lastas

  I'm developing a simple bar-chart in Reporting Services 2005 with a stored procedure as data-source. The values in this graph can be both positive and negative, and can span a very big range, and hence I cannot specify any non-dynamic scale that will work for all scenarios. The problem I'm facing is that the automatic scaling pretty much sucks. I get no line to show where the zero-point is, and the y-scale labels are from top to bottom: 8818 -191181 -391181 etc etc... So my question is, what is the best approach to make the scale more adapted to human reading? Is there any guide out there? Does reporting services 2008 handle this better? Also, moving away from Reporting Services is not really an option. I realize how to put values and expression in the max, min, and the gridline interval fields, although its more of a question what expressions I should put there.

• How to get a variable name as a string in Python?

  - by e-satis

  I would like to be able to get the name of a variable as a string but I don't know if Python has that much introspection capabilities. Something like: >>> print(my_var.__name__) 'my_var' I want to do that because I have a bunch of vars I'd like to turn into a dictionary like : bar=True foo=False >>> my_dict=dict(bar=bar, foo=foo) >>> print mydict >>> print my_dict {'foo': False, 'bar': True} But I'd like something more automatic than that. Python have locals() and vars(), so I guess there is a way.

• Speed of Synchronization vs Normal

  - by Swaranga Sarma

  I have a class which is written for a single thread with no methods being synchronized. class MyClass implements MyInterface{ //interface implementation methods, not synchronized } But we also needed a synchronized version of the class. So we made a wrapper class that implements the same interface but has a constructor that takes an instance of MyClass. Any call to the methods of the synchronized class are delegated to the instance of MyClass. Here is my synchronized class.. class SynchronizedMyClass implements MyInterface{ //the constructor public SynchronizedMyClass(MyInterface i/*this is actually an instance of MyClass*/) //interface implementation methods; all synchronized; all delegated to the MyInterface instance } After all this I ran numerous amounts of test runs with both the classes. The tests involve reading log files and counting URLs in each line. The problem is that the synchronized version of the class is consistently taking less time for the parsing. I am using only one thread for the teste, so there is no chance of deadlocks, race around condition etc etc. Each log file contains more than 5 million lines which means calling the methods more than 5 million times. Can anyone explain why synchronized versiuon of the class migt be taking less time than the normal one?

• Question about custom events

  - by Malfist

  I'm making custom events for C# and sometimes it isn't working. This is how I'm making the event happen: private bool isDoorOpen; public bool IsDoorOpen { get { return isDoorOpen;} private set { isDoorOpen = value; DoorsChangeState(this, null);} } And these are the event declarations: //events public delegate void ChangedEventHandler(Elevator sender, EventArgs e); public event ChangedEventHandler PositionChanged; public event ChangedEventHandler DirectionChanged; public event ChangedEventHandler BreaksChangeState; public event ChangedEventHandler DoorsChangeState; This works as long as there are methods attached to the events, but if there isn't, it throws a null ref exception. What am I doing wrong?

• Cross version line matching.

  - by BCS

  I'm considering how to do automatic bug tracking and as part of that I'm wondering what is available to match source code line numbers (or more accurate numbers mapped from instruction pointers via something like addr2line) in one version of a program to the same line in another. (Assume everything is in some kind of source control and is available to my code) The simplest approach would be to use a diff tool/lib on the files and do some math on the line number spans, however this has some limitations: It doesn't handle cross file motion. It might not play well with lines that get changed It doesn't look at the information available in the intermediate versions. It provides no way to manually patch up lines when the diff tool gets things wrong. It's kinda clunky Before I start diving into developing something better: What already exists to do this? What features do similar system have that I've not thought of?

• xml parsing takes extra spaces.

  - by SDK

  I have been trying to write/parse xml file in python. The tags are very simple <main> <data> abcdef </data> </main> I have written this xml using xml document writer from xml.dom.minidom. How-ever when i try to parse this and try to fetch data-text value, i get 'abcdef' with spaces/carriage return/newline characters in beg and end. Does parsing does not take of indenting spaces? Following is the parsing snippet (ref from net) dom = parseString(data) clipTag = dom.getElementsByTagName('clipdata')[0].toxml() clipData=clipTag.replace('<clipdata>','').replace('</clipdata>','') Kindly suggest.

• Oracle checking existence before deletion in a trigger

  I have analyzed a hibernate generated oracle database and discovered that a delete of a row from a single table will spawn the firing of 1200+ triggers in order to delete the related rows in child tables. The triggers are all auto-generated the same - an automatic delete of a child row without checking for existence first. As it is impossible to predict which child tables will actually have related rows, I think a viable solution to preventing the firing of the cascaded delete down a deeply branched completely empty limb, would be to check for the existence of a related row before attempting to delete. In other dbms', I could simply state " if exists....." before deleting. Is there a comparable way to do this in oracle?

• Extracting friends' E-Mail addresses from Facebook (Skype?)

  - by chephy

  I am currently in the process of migrating away from Facebook (privacy concerns, mostly). For obvious reasons, I want to save away the email addresses from my friends' profile pages. However, this turned out to be a rather hard task, because the Facebook API doesn't let you access any mail addresses. However, I just tried the automatic contact import feature of Skype, and it seems to be able to retrieve the email addresses of my friends from Facebook. Does anyone know how it's done so I could replicate it?

• "And" condition in C#/LINQ Query

  - by user1213055

  partial void PrintDocLetter1_CanExecute(ref bool result) { if (this.PatientsMasterItem.DoctorsMasterItem != null) { var Doctor = PatientsMasterItem.DoctorsMasterItem; var PatientList = Doctor.PatientsMasterItem; var Letters = PatientsMasterItem.LettersSentItem; if ((PatientList.Count() > 1) && (Letters.Any(i => i.LetterType == "DoctorLetter1"))) { result = false; } else { result = true; } } } I think something is wrong with my second condition. I'm trying to find two things. 1) Doctors with more than 1 patient. 2) Among those patients whether a lettertype called "DoctorLetter1" has been sent or not. The above code is working good for that particular record but not working other patients with same doctors where patient1 has already been sent with DoctorLetter1.

  Hi!, I have setup svnserve server (1.6.5,plain, without apache) on Fedora. The users, who has accounts in same machine want to checkout a working copy.

As svnbook also says "Clients contact an svnserve server by using URLs that begin with the svn://" So, my question is, which method user will use to create their working copy? Thankyou. Banani

• Sort a DataGridView by DisplayMember

  - by Dave

  Hi, I have a DataGridView that is bound to a DataTable. In this table there are some foreign keys. I am then using the CellFormatting event to get the corresponding text from another database table for each foreign key. I want to sort the DataGridView when the user clicks the header. Automatic sorting works but is not correct as it is Sorting on the ValueMember (ForeignKey ID) and not on the DisplayMember (the text). I tried using the SortCompare event but then I read that it does not work on DataGridViews that use the DataSource property. How can this be done? Thanks

• set countdown correctly, as3

  - by VideoDnd

  How can I set my countdown correctly? I'm counting from 33,000.00 to zero. It works in a fashion, but the minus operator appears in the textfield. //Countdown from 33,000.00 to zero var timer:Timer = new Timer(10); var count:int = -3300000; var fcount:int = 0; timer.addEventListener(TimerEvent.TIMER, incrementCounter); timer.start(); function incrementCounter(event:TimerEvent) { count++; fcount=int(count); mytext.text = formatCount(fcount); } function formatCount(i:int):String { var fraction:int = i % 100; var whole:int = i / 100; return ("0000000" + whole).substr(-7, 7) + "." + (fraction < 10 ?

• I am getting duplicates in UITableView, cellForRowAtIndexPath

  - by Martol1ni

  I am getting duplicates of my array, and wrongly displayed cells in this method: Here I am initializing the array, and adding it to the tableView: NSArray *sectionsArray = [NSArray arrayWithObjects: @"Location", @"Front Post", @"Front Fixing", @"Front Footplate", @"Rear Post", @"Read Fixing", @"Rear Footplate", @"Horizontal Bracing", @"Diagonal Bracing", @"Front Beam", @"Front Lock", @"Rear Beam", @"Rear Lock", @"Guard", @"Accessories", @"Comments", @"Off load ref", @"Loc Empty", @"Loc Affected", nil]; [_tableArray setObject:sectionsArray atIndexedSubscript:2]; [_tableView reloadData]; For some weird reason there are always the 4th object that is messed up, and is either duplicated, or do not have the views from IB. Here is the cellForRowAtIndexPath: method: - (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell; if (indexPath.section == 2) { cell = [tableView dequeueReusableCellWithIdentifier:@"EntryCell"]; cell.tag = indexPath.row; UILabel *label = (UILabel *)[cell viewWithTag:3]; [label setText:[[_tableArray objectAtIndex:2] objectAtIndex:indexPath.row]]; } return cell; } I have logged the string [[_tableArray objectAtIndex:2] objectAtIndex:indexPath.row], and it logs the right string.

• Is there a tool that automatically saves incremental changes to files while coding?

  - by Bob.

  One of my favorite features of Google docs is the fact that it's constantly automatically saving versions of my document as I work. This means that even if I forget to save at a certain point before making a critical change there's a good chance that a save point has been created automatically. At the very least, I can return the document to a state prior to the mistaken change and continue working from that point. Is there a tool with an equivalent feature for a Ruby coder running on Mac OS (or UNIX)? For example, a tool that will do an automatic Git check-in every couple of minutes to my local repository for the files I'm working on. Maybe I'm paranoid, but this small bit of insurance could put my mind at ease during my day-to-day work.

• Which MySQL Datatype to use for storing boolean values from/to PHP?

  - by Beat

  Since MySQL doesn't seem to have any 'boolean' datatype, which datatype do you 'abuse' for storing true/false information in MySQL? Especially in the context of writing and reading from/to a PHP-Script. Over time I have used and seen several approaches: tinyint, varchar fields containing the values 0/1, varchar fields containing the strings '0'/'1' or 'true'/'false' and finally enum Fields containing the two options 'true'/'false'. None of the above seems optimal, I tend to prefer the tinyint 0/1 variant, since automatic type conversion in PHP gives me boolean values rather simply. So which datatype do you use, is there a type designed for boolean values which I have overlooked? Do you see any advantages/disadvantages by using one type or another?
