• What is the best way to go about grouping rows by the same timestamp?

  - by Luke

  Hello all. I am looking for some advice. I have rows of data in the database that i want to group together. There is a timestamp involved. That column is called date. What is the best way to go about grouping rows by the same timestamp. EDITED..... <? $result = mysql_query("SELECT * FROM ".TBL_FIXTURES." ORDER BY date"); $current_week = null; while ($row = mysql_fetch_assoc($result)) { if ($row['date'] != $current_week) { $current_week = $row['date']; echo 'Week ' . $current_week .': '; } echo $row['home_user']; echo $row['home_team']; echo $row['away_user']; echo $row['away_team']; } ?> I have this code. What i am trying to do is organise each round of fixtures in a row with a title Week 1 - date. I want Week 1 and the date and all fixtures with that date displayed. Then move onto week 2 and the date and all fixtures again. This should be done for every fixture in the database, so if there are 6 rounds of fixtures, there will be 6 dates and therefore 6 blocks of fixtures.. Please help, thanks

• Memory leak in PHP with Symfony + Doctrine

  - by Nicklas Ansman

  I'm using PHP with the Symfony framework (with Doctrine as my ORM) to build a spider that crawls some sites. My problem is that the following code generates a memory leak: $q = $this -> createQuery('Product p'); if($store) { $q -> andWhere('p.store_id = ?', $store -> getId()) -> limit(1); } $q -> andWhere('p.name = ?', $name); $data = $q -> execute(); $q -> free(true); $data -> free(true); return NULL; This code is placed in a subclass of Doctrine_Table. If I comment out the execute part (and of course the $data - free(true)) the leak stops. This has led me to the conclusion that it's the Doctrine_Collection that's causing the leak. Any ideas on what I can do to fix this? I'd be happy to provide more info on the problem if you need it. Regards Nicklas

• Code Analysis Warning CA1004 with generic method

  - by Vaccano

  I have the following generic method: // Load an object from the disk public static T DeserializeObject<T>(String filename) where T : class { XmlSerializer xmlSerializer = new XmlSerializer(typeof(T)); try { TextReader textReader = new StreamReader(filename); var result = (T)xmlSerializer.Deserialize(textReader); textReader.Close(); return result; } catch (FileNotFoundException) { } return null; } When I compile I get the following warning: CA1004 : Microsoft.Design : Consider a design where 'MiscHelpers.DeserializeObject(string)' doesn't require explicit type parameter 'T' in any call to it. I have considered this and I don't know a way to do what it requests with out limiting the types that can be deserialized. I freely admit that I might be missing an easy way to fix this. But if I am not, then is my only recourse to suppress this warning? I have a clean project with no warnings or messages. I would like to keep it that way. I guess I am asking "why this is a warning?" At best this seems like it should be a message. And even that seems a bit much. Either it can or it can't be fixed. If it can't then you are just stuck with the warning with no recourse but suppressing it. Am I wrong?

• INSERT..ON DUPLICATE KEY UPDATE - but NOT using the duplicate key to compare.

  - by calumbrodie

  I am trying to solve a problem I have inherited with poor treatment of different data sources. I have a user table that contains BOTH good and evil users. create table `users`( `user_id` int(13) NOT NULL AUTO_INCREMENT , `email` varchar(255) , `name` varchar(255) , PRIMARY KEY (`user_id`) ); In this table the primary key is currently set to be user_id. I have another table ('users_evil') which contains ONLY the evil users (all the users from this table are included in the first table) - the user_id's on this table do NOT correspond to those in the first table. I want to have all my users in one table, and simply flag which are good and which are evil. What I want to do is alter the user table and add a column ('evil') which defaults to 0. I then want to dump the data from my 'users_evil') table and then run an INSERT..ON DUPLICATE KEY UPDATE with this data into the first table (setting 'evil'=1 where the emails match) The problem is that the 'PK' is set to the user_id and not the 'email'. Any suggestions, or even another strategy to successfully achive this. Can I run this statement but treat another column as PK only for the duration of the statement.

• How to access a variable outside a function in Javascript

Am I missing something here?

• xpath php attributes not working?

  - by Jared

  Getting this error Call to a member function attributes() on a non-object I have found multiple answers to this on SO, but none of them seem to solve my problem? Here is the XML: <Routes> <Route type="source" name="incoming"> </Route> <Routes> Here is the PHP: $doc = new SimpleXMLElement('routingConfig.xml', null, true); class traverseXML { function getData() { global $doc; $routeCount = count($doc -> xpath("Route")); //this value returns correctly $routeArr = array(); for ($i = 1; $i <= $routeCount; $i++) { $name = $doc -> Route[$i] -> attributes() -> name; array_push($routeArr, $name); } return $routeArr; } } $traverseXML = new traverseXML; var_dump($traverseXML -> getData()); I understand what the error means, but how is it a non-object? How do I return the name attribute of Routes/Route[1] ?

• How can I dynamically set the default namespace declaration of an XSLT transformation's output XML?

  - by Paralife

  I can do it, but not for the default namespace, using the <xsl:namespace>. If I try to do it for the default namespace: <xsl:namespace name="" select"myUri"/> it never works. It demands that I explicitly define the namespace of the element to be able to use the above null prefix declaration. The reason I want this is because I have a task to transform an input XML file to another output xml. The output XML has many elements and i dont want to have to explicitly set the namespace for every element. Thats why I want to set the default and never bother again. But the default must be computed from some data in the source XML. It does not change during the whole transformation, but it is dependent on input XML data. Any solution? EDIT 1: To sup up: I want to create a namespace dynamically and set it to be the default namespace of the output xml document. The uri of the namespace is derived from some data in the input XML. If I use <xsl:namespace> in my root output element, I cannot create a default namespace for it, only a prefixed one. And even with the prefixed one, it does not propagate to children.

• Java SOAP - Need help on Body and ChildElement manipulation

  - by techventure

  Hi guys I'm trying to write some code in java to learn more about coding with WSDL and SOAP. I've been able to build up a BodyElement for a given namespace. But when i come to adding the childElements I'm runnig intp problems. For example given :'<'to:checkAccount xmlns:to="http://foo" '<'to:id test' <'/to:id '<'to:password test '<'/to:password '<'to:checkAccount " I'm able to set the bodyElement(to:checkAccount), but when i try to add the childElements (to:id, to:password) , the childElement needs to have the "to" prefix otherwise it won't work. ie. sf = SOAPFactory.newInstance(); Name childName = sf.createName("id"); SOAPElement symbol = bodyElement.addChildElement(childName); this doesn't work since it doesn't have the "to" prefix to id and password. I cannot do Name childName = sf.createName("id","to",null); as it gives me an error saying wrong namespace... can someone tell me how i can add to:id and to:password to to:checkAccount ?

• How to clip and fill a canvas using an alpha mask

  - by Jay Koutavas

  I have some .png icons that are alpha masks. I need to render them as an drawable image using the Android SDK. On the iPhone, I use the following to get this result, converting the "image" alpha mask to the 'imageMasked' image using black as a fill: CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, thumbWidth, thumbHeight, 8, 4*thumbWidth, colorSpace, kCGImageAlphaPremultipliedFirst); CGRect frame = CGRectMake(0,0,thumbWidth,thumbHeight); CGContextClipToMask(context, frame, [image CGImage]); CGContextFillRect(context, frame); CGImageRef imageMasked = CGBitmapContextCreateImage(context); CGContextRelease(context); How do I accomplish the above in Android SDK? I've started to write the following: Drawable image = myPngImage; final int width = image.getMinimumWidth(); final int height = image.getMinimumHeight(); Bitmap imageMasked = Bitmap.createBitmap(width, height, Config.ARGB_8888); Canvas canvas = new Canvas(iconMasked); image.draw(canvas); ??? I'm not finding how to do the clipping on imageMasked using image.

• Does this copy the reference or the object?

  - by Water Cooler v2

  Sorry, I am being both thick and lazy, but mostly lazy. Actually, not even that. I am trying to save time so I can do more in less time as there's a lot to be done. Does this copy the reference or the actual object data? public class Foo { private NameValueCollection _nvc = null; public Foo( NameValueCollection nvc) { _nvc = nvc; } } public class Bar { public static void Main() { NameValueCollection toPass = new NameValueCollection(); new Foo( toPass ); // I believe this only copies the reference // so if I ever wanted to compare toPass and // Foo._nvc (assuming I got hold of the private // field using reflection), I would only have to // compare the references and wouldn't have to compare // each string (deep copy compare), right? } I think I know the answer for sure: it only copies the reference. But I am not even sure why I am asking this. I guess my only concern is, if, after instantiating Foo by calling its parameterized ctor with toPass, if I needed to make sure that the NVC I passed as toPass and the NVC private field _nvc had the exact same content, I would just need to compare their references, right?

• Namespace scoped aliases for generic types in C#

  - by TN

  Let's have a following example: public class X { } public class Y { } public class Z { } public delegate IDictionary<Y, IList<Z>> Bar(IList<X> x, int i); public interface IFoo { // ... Bar Bar { get; } } public class Foo : IFoo { // ... public Bar Bar { get { return null; //... } } } void Main() { IFoo foo; //= ... IEnumerable<IList<X>> source; //= ... var results = source.Select(foo.Bar); } The compiler says: The type arguments for method 'System.Linq.Enumerable.Select(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly. It's because, it cannot convert Bar to Func<IList<X>, int, IDictionary<Y, IList<Z>>>. It would be great if I could create type namespace scoped type aliases for generic types in C#. Then I would define Bar not as a delegate, but rather I would define it as an namespace scoped alias for Func<IList<X>, int, IDictionary<Y, IList<Z>>>. public alias Bar = Func<IList<X>, int, IDictionary<Y, IList<Z>>>; I could then also define namespace scoped alias for e.g. IDictionary<Y, IList<Z>>. And if used appropriately:), it will make the code more readable. Now I have inline the generic types and the real code is not well readable:( Have you find the same trouble:)? Is there any good reason why it is not in C# 3.0? Or there is no good reason, it's just matter of money and/or time? EDIT: I know that I can use using, but it is not namespace based - not so convenient for my case.

• JTable cells not rendering shapes properly

  - by Andrew

  I'm trying to render my JTable cells with a subclassed JPanel and the cells should appear as coloured rectangles with a circle drawn on them. When the table displays initially everything looks OK but then when a dialog or something is displayed over the cells when it is removed the cells that have been covered do not rendered properly and the circles are broken up etc. I then have to move the scroll bar or extend the window to get them to redraw properly. The paintComponent method of the component I'm using to render the cells is below: protected void paintComponent(Graphics g) { setOpaque(true); super.paintComponent(g); Graphics2D g2d = (Graphics2D) g; GradientPaint gradientPaint = new GradientPaint(new Point2D.Double(0, 0), Color.WHITE, new Point2D.Double(0, getHeight()), paintRatingColour); g2d.setPaint(gradientPaint); g2d.fillRect(0, 0, getWidth(), getHeight()); g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); g2d.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY); Rectangle clipBounds = g2d.getClipBounds(); int x = new Double(clipBounds.getWidth()).intValue() - 15; int y = (new Double(clipBounds.getHeight()).intValue() / 2) - 6; if (level != null) { g2d.setColor(iconColour); g2d.drawOval(x, y, width, height); g2d.fillOval(x, y, width, height); } }

• Full and Partial Matching of Sets

  - by jeffrey

  I have several sets of the same type [Y, M, D] and am trying to write a function to search these sets and return an array of the available sets that fit my parameters. ReturnedSets = return_matches(Y,M,D); I want the three parameters of the function return_matches to be optional. Which means any combination of values can be used to return the sets. For example, one could write - return_matches(13,null,2); - and the function would look for all sets that contain [13, anyValue, 2]; I'm writing this in PHP, to allow users to manage dated files on my website, but I'd like to be able to use this function again for other uses. Thanks! edit: (This, or variations of this, is all I can come up with so far... There is something extra that I don't understand, because this function ends up / would not work to return sets that contain y and d, but leaving m arbitrary. if(y == s[0]){ if(m == s[1]){ if(d == s[2]){ print "day match"; } } else {print "month match";} } else {print "year match";} } else {print "no match";}

• java + increasing performance and scalability

• Problem reading in file written with xdr using c

  - by Inga

  I am using Ubuntu 10.4 and have two (long) C programs, one that writes a file using XDR, and one that uses this file as input. However, the second program does not manage to read in the written file. Everything looks perfectly fine, it just does not work. More spesifically it fails at the last line added here with the error message xdr_string(), which indicates that it can not read in the first line of the input file. I do no see any obvious errors. The input file is written out, have a content and I can see the right strings using stings -a -n 2 "inputfile". Anyone have any idea what is going wrong? Relevant parts of program 1 (writer): /** * create compressed XDR output stream */ output_file=open_write_pipe(output_filename); xdrstdio_create(&xdrs, output_file, XDR_ENCODE); /** * print material name */ if( xdr_string(&xdrs, &name, _POSIX_NAME_MAX) == FALSE ) xdr_err("xdr_string()"); Relevant parts of program 2 (reader): /** * open data file */ input_file=open_data_file(input_filename, "r"); if( input_file == NULL ){ ERROR(input_filename); exit(EXIT_FAILURE); } /** * create input XDR stream */ xdrstdio_create(&xdrs, input_file, XDR_DECODE); /** * read material name */ if(xdr_string(&xdrs, &name, _POSIX_NAME_MAX) == FALSE) XDR_ERR("xdr_string()");

• Linq to Entities Joins

  - by Bob Avallone

  I have a question about joins when using Linq to Entities. According to the documentation the use on the join without a qualifier performs like a left outer join. However when I execute the code below, I get a count returned of zero. But if I comment out the three join lines I get a count of 1. That would indicate that the join are acting as inner join. I have two questions. One which is right inner or outer as the default? Second how do I do the other one i.e. inner or outer? The key words on inner and outer do not work. var nprs = (from n in db.FMCSA_NPR join u in db.FMCSA_USER on n.CREATED_BY equals u.ID join t in db.LKUP_NPR_TYPE on n.NPR_TYPE_ID equals t.ID join s in db.LKUP_AUDIT_STATUS on n.NPR_STATUS_ID equals s.ID where n.ROLE_ID == pRoleId && n.OWNER_ID == pOwnerId && n.NPR_STATUS_ID == pNPRStatusId && n.ACTIVE == pActive select n).ToList(); if (nprs.Count() == 0) return null;

• Create ImageButton programatically depending on local database records

  - by user2507920

  As i described in title, i have a local db in sqlite. I want to create ImageButton parametrically. How many times is local database loop executing? Please see code below : RelativeLayout outerRelativeLayout = (RelativeLayout)findViewById(R.id.relativeLayout2_making_dynamically); db.open(); Cursor c = db.getAllLocal_Job_Data(); if(c!=null){ if(c.moveToFirst()){ do { RelativeLayout innerRelativeLayout = new RelativeLayout(CalendarActivity.this); innerRelativeLayout.setGravity(Gravity.CENTER); ImageButton imgBtn = new ImageButton(CalendarActivity.this); imgBtn.setBackgroundResource(R.drawable.color_001); RelativeLayout.LayoutParams imageViewParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT); imgBtn.setLayoutParams(imageViewParams); // Adding the textView to the inner RelativeLayout as a child innerRelativeLayout.addView(imgBtn, new RelativeLayout.LayoutParams( ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); outerRelativeLayout.addView(innerRelativeLayout, new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); } while (c.moveToNext()); } } db.close(); But when i run the project, i can see only one button created there. I think there are many buttons but here image button is creating on last created image button. I think i should use android:layout_toRightOf with previous created button but i cant find how to place it here. I have tried some ideas but it did not change any thing. So please anybody has any idea to solve my problem then please share it with me.

• R Random Data Sets within loops

  - by jugossery

  Here is what I want to do: I have a time series data frame with let us say 100 time-series of length 600 - each in one column of the data frame. I want to pick up 4 of the time-series randomly and then assign them random weights that sum up to one (ie 0.1, 0.5, 0.3, 0.1). Using those I want to compute the mean of the sum of the 4 weighted time series variables (e.g. convex combination). I want to do this let us say 100k times and store each result in the form ts1.name, ts2.name, ts3.name, ts4.name, weight1, weight2, weight3, weight4, mean so that I get a 9*100k df. I tried some things already but R is very bad with loops and I know vector oriented solutions are better because of R design. Thanks Here is what I did and I know it is horrible The df is in the form v1,v2,v2.....v100 1,5,6,.......9 2,4,6,.......10 3,5,8,.......6 2,2,8,.......2 etc e=NULL for (x in 1:100000) { s=sample(1:100,4)#pick 4 variables randomly a=sample(seq(0,1,0.01),1) b=sample(seq(0,1-a,0.01),1) c=sample(seq(0,(1-a-b),0.01),1) d=1-a-b-c e=c(a,b,c,d)#4 random weights average=mean(timeseries.df[,s]%*%t(e)) e=rbind(e,s,average)#in the end i get the 9*100k df } The procedure runs way to slow. EDIT: Thanks for the help i had,i am not used to think R and i am not very used to translate every problem into a matrix algebra equation which is what you need in R. Then the problem becomes a little bit complex if i want to calculate the standard deviation. i need the covariance matrix and i am not sure i can if/how i can pick random elements for each sample from the original timeseries.df covariance matrix then compute the sample variance (t(sampleweights)%*%sample_cov.mat%*%sampleweights) to get in the end the ts.weighted_standard_dev matrix Last question what is the best way to proceed if i want to bootstrap the original df x times and then apply the same computations to test the robustness of my datas thanks

• Synfony2 validation changes invalid integer to 0

  - by Craig

  I've added validation to a form and found that in some cases it is losing the invalid data I am feeding it and saving 0s instead. The output at the bottom shows that if I post the latitude as 'zzzzzz' (clearly not a number nor between -90 and 90) the form is declared as valid and saved with the value 0 How can that happen given that I have declared the input must be a number?

• Validating a phone number in Android PreferenceScreen

  - by djechelon

  I have a PreferenceScreen in which the user is capable, if system can't autodetect it, to enter the device's phone number. I'm still learning this part of Android but I managed to understand a bit of PreferenceScreens by examples provided by Android SDK itself and a few tutorials. What I want is that the user can save the phone number only if null or valid, where by "valid" I mean running a generic validation logic (ie. an anonymous method that returns true or false, that can be reused in any possible situation*) or better, just to simplify things, ^(\+39)?3[0-9]{9}$ For now I have the following XML snip <EditTextPreference android:inputType="phone" android:key="@string/preference_phoneNo" android:selectAllOnFocus="true" android:singleLine="true" android:summary="@string/pref_phoneNumber_description" android:title="@string/pref_phoneNumber" /> and following code by courtesy of Eclipse New Activity wizard: private void setupSimplePreferencesScreen() { if (!isSimplePreferences(this)) { return; } addPreferencesFromResource(R.xml.pref_general); bindPreferenceSummaryToValue(findPreference(getString(R.string.preference_phoneNo))); } addPreferenceFromResource is supposed to load the XML node and add the preference to the screen, while binPreferenceSummaryToValue is supposed to make description text change when preference is updated. Just for sake of completeness for those who don't like code courtesy of the IDE, the second method is provided by Eclipse who also provides a private class in the code file that is /** * A preference value change listener that updates the preference's summary * to reflect its new value. */ In the general case, what should I do to perform validation logic before the preference gets saved when I click OK on the preference editor? Where is the validation logic to be put in a PreferenceScreen? *Aren't we all here to learn?

  I have the following function from some legacy code that I am maintaining. long getMaxStart(long start, long count, const myStruct *s1, ...) { long i1, maxstart; myStruct *s2; va_list marker; maxstart = start; /*BUGFIX: 003 */ /*(va_start(marker, count);*/ va_start(marker, s1); for (i1 = 1; i1 <= count; i1++) { s2 = va_arg(marker, myStruct *); /* <- s2 is assigned null here */ maxstart = MAX(maxstart, s2->firstvalid); /* <- SEGV here */ } va_end(marker); return (maxstart); } When the function is called with only one myStruct argument, it causes a SEGV. The code compiled and run without crashing on an XP, when I compiled it using VS2005. I have now moved the code to Ubuntu Karmic and I am having problems with the stricter compiler on Linux. Is anyone able to spot what is causing the parameter not to be read correctly in the var_arg() statement? I am compiling using gcc version 4.4.1

• progressbar not updating binding

  - by BoteRock

  I am trying to make a progress bar that updates when a property value changes I have followed other questions but i don't know what is wrong with it. This is XAML code: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" x:Class="WpfApplication1.MainWindow" Title="MainWindow"> <Grid Margin="0,0,-8,1"> <ProgressBar Value="{Binding Progreso, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:MainWindow}}}" Margin="105,95,207,350"/> <Button Content="Button" Click="Button_Click" Margin="218,232,333,217"/> </Grid> </Window> it is basically a progress bar with the binding and a button with a listener that increases Progreso by 10 this is the C# code: public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } public event PropertyChangedEventHandler PropertyChanged; protected void NotifyPropertyChanged(string sProp) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(sProp)); } } float progreso = 10; public float Progreso { get { return progreso; } set { progreso = value; NotifyPropertyChanged("Progreso"); } } private void Button_Click(object sender, RoutedEventArgs e) { this.Progreso = this.Progreso + 10; } } I tried to keep it simple but I couldn't get it to work, any help with this would be appreciated. edit: I've also tried UpdateSourceTrigger=PropertyChanged and that didn't work either

• Problem with configure script

  - by cube

  I am running into a problem with the ./configure script for ffmpeg. My linux environment uses busybox, which only allows for limited set of linux commands. One command which is used in the ffmpeg ./configure script is mktemp -u, the problem here is the busybox for linux does not recognize the -u switch as valid, so it complains about it and breaks the configure process. This is the relevant code in ./configure which uses the mktemp -u command: if ! check_cmd type mktemp; then # simple replacement for missing mktemp # NOT SAFE FOR GENERAL USE mktemp(){ echo "${2%XXX*}.${HOSTNAME}.${UID}.$$" } fi tmpfile(){ tmp=$(mktemp -u "${TMPDIR}/ffconf.XXXXXXXX")$2 && (set -C; exec > $tmp) 2>/dev/null || die "Unable to create temporary file in $TMPDIR." append TMPFILES $tmp eval $1=$tmp } I am not good with bash scripting at all, so I was wondering if anyone one had an idea on how I can force this configure script to not use mktemp -u and use the 'replacement' alternative option that is available in as per the snippet above. Thanks. btw... simply removing the -u switch does not work. Nor does replacing it with -t, or -p. I believe the mktemp has to be bypassed completely.
