• DNS-Based Environment Determination

  - by zvolkov

  Found the following here. The questions is: where can I find more details on how exactly implement this on Windows? Any guide or how-to anybody? Or maybe you can provide your invaluable suggestions? Specifically, how do I make so that "all QA servers would first resolve entries in qa.example.com first and then if that lookup failed they would try example.com" (I'm a dev, not a DNS specialist, but our IT Support has refused to help on this:() Use DNS Based Environment Determination for your servers. Do this by initially splitting your top level domain into a number of sub domains depending on their function, and then creating DNS Service Names in each of the sub domains pointing to the relevant server for that service. Based on the list above we would then have: * clientdb.prod.example.com for Production * clientdb.perf.example.com for Performance Testing * clientdb.qa.example.com for QA * clientdb.dev.example.com for Development Servers then resolve entries in their relevant sub domain by function. That is, all QA servers would first resolve entries in qa.example.com first and then if that lookup failed they would try example.com. This allows you to have a single configuration entry for your client database hostname (clientdb) that would resolve correctly in all environments. This technique has the added advantage of still having global services defined in a common top level domain. Here's one related (but not equivalent) SO question: http://stackoverflow.com/questions/774490/dns-resolving-based-on-client-ip This seems to be related to Providing "split horizon" DNS service. Reading that, I see that I will probably need separate DNS Server for each environment. Is this true or does Windows support some form of "tagging" the records to be visible depending on the requestor's IP? Also, cross-posted on ServerFault

• How to get checked items in a WPF ListBox?

  - by Joan Venge

  I have a WPF ListBox where I have checkboxes, but what's the way to get the list of items that are checked? The ListBox is data binded to a Dictionary<T>. Here is the XAML: <Window x:Class="WpfApplication.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid Margin="10"> <ListBox ItemsSource="{DynamicResource Nodes}" Grid.IsSharedSizeScope="True" x:Name="MyList"> <ListBox.ItemTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition SharedSizeGroup="Key" /> <ColumnDefinition SharedSizeGroup="Name" /> <ColumnDefinition SharedSizeGroup="Id" /> </Grid.ColumnDefinitions> <CheckBox Name="NodeItem" Click="OnItemChecked"> <StackPanel Orientation="Horizontal"> <TextBlock Margin="2" Text="{Binding Value.Name}" Grid.Column="1"/> <TextBlock Margin="2" Text="-" Grid.Column="2"/> <TextBlock Margin="2" Text="{Binding Value.Id}" Grid.Column="3"/> </StackPanel> </CheckBox> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Grid> </Window>

• Retrieve click() handler in jQuery for later use

  - by Xiong Chiamiov

  I'm using the jQuery tablesorter plugin to sort a table, which assigns .click() handlers to the <th>s in the table. Since my table has alternating colors for each column, I've built a simple fix_table_colors(identifier) function that does as it should when I call it manually using Firebug. I would like, however, to have that automatically called after a sort. To do this, I decided to retrieve the .click() handler from the <th>s, and assign a new handler that simply calls the previous handler, followed by fix_table_colors(). (This SO question is similar, but uses standard onClick() attributes, which won't work here.) From the accepted answer to this question, I have created the following code: $(document).ready(function() { $("table.torrents").tablesorter({ debug: true, headers: { 1: { sorter: 'name' }, 2: { sorter: 'peers' }, 3: { sorter: 'filesize' }, 4: { sorter: 'filesize' }, 5: { sorter: 'filesize' }, 6: { sorter: 'ratio' } } }); $('table.torrents thead th').each(function() { var th = $(this); var clickHandler = th.data('events').click[0]; th.click(function() { clickHandler(); fix_table_colors('table.torrents'); }); }); }); While this is conceptually correct, clickHandler doesn't appear to actually be a function, and so I cannot call it. With a bit more digging in Firebug, I found that click[3] appears to hold the function I'm looking for (and click[10] my new one). I get an 'e is undefined' error on line 2 of tablesorter.min.js when using that, though. Am I even going down the right path? I have a feeling that with what I've found so far, I can make this work, but it's going to be much uglier than I would expect it needs to be.

• PHP readfile() and large downloads

  - by Nirmal

  While setting up an online file management system, and now I have hit a block. I am trying to push the file to the client using this modified version of readfile: function readfile_chunked($filename,$retbytes=true) { $chunksize = 1*(1024*1024); // how many bytes per chunk $buffer = ''; $cnt =0; // $handle = fopen($filename, 'rb'); $handle = fopen($filename, 'rb'); if ($handle === false) { return false; } while (!feof($handle)) { $buffer = fread($handle, $chunksize); echo $buffer; ob_flush(); flush(); if ($retbytes) { $cnt += strlen($buffer); } } $status = fclose($handle); if ($retbytes && $status) { return $cnt; // return num. bytes delivered like readfile() does. } return $status; } But when I try to download a 13 MB file, it's just breaking at 4 MB. What would be the issue here? It's definitely not the time limit of any kind because I am working on a local network and speed is not an issue. The memory limit in PHP is set to 300 MB. Thank you for any help.

• How can I load a Class contained in a website from a DLL referenced by that website???

  - by Morgeh

  Ok so this is alittle bit obscure and I'm not sure its the best way of doing what I'm trying to do but here goes. Basically I have a Presentation Layer Dll in my web site which handles the Model View Presenter classes. The presentation layer also handles login for my website and then calls off to a web service. Currently whenever the presentation layer calls to a model it verifies the users details and if they are invalid it calls to a loginHandler which redirects the user to the login page. However I cannot dynamically load a new istance of the Login Page in my website from within my Presentation layer. I've tried to use reflection to dynamically load the class but Since the method call is in the presentation assembly it is only looking within that assembly while the page I want to load is in the website. heres the reflection code that loads the View: public ILoginView LoadView() { string viewName = ConfigurationManager.AppSettings["LoginView"].ToString(); Type type = Type.GetType(viewName, true); object newInstance = Activator.CreateInstance(type); return newInstance as ILoginView; } Anyone got any suggestions on how to search within the website assembly? Ideal I don't want to tie this implementation into the website specifically as the presentation layer is also used in a WPF application.

• Handling events from user control containing a WPF textbox

  - by Tom

  I've been successful in putting a WPF textbox into an existing windows form using ElementHost and a user control. It looks like the following: Public Class MyUserControl Private _elementHost as ElementHost = New ElementHost Private _wpfTextbox as System.Windows.Controls.Textbox = New System.Windows.Controls.Textbox Public Sub New() Me.Controls.Add(_elementHost) _elementHost.Dock = DockStyle.Fill _elementHost.Child = _wpfTextbox _wpfTextbox.SpellCheck.IsEnabled = True End Sub End Class Now, when I put this user control onto a windows form, it accepts keyboard input and the form itself can get text from the textbox. However, when I try to handle keypress (or keydown, keyup) events from the user control, nothing happens. I've looked into this problem and did a bit of research but now I'm a little confused as to what I really need to be looking at. The following are the topics that I am somewhat confused about. HwndSource Relaxed delegates WPF routed events If I am interpreting everything correctly, input from WPF textboxes are handled differently compared to regular form textboxes. It seems like both aren't compatible with each other but there must be some way to "pass" keys from one to another? I'd appreciate any help.

• JTree events seem misordered

  - by MeBigFatGuy

  It appears to me that tree selection events should happen after focus events, but this doesn't seem to be the case. Assume you have a JTree and a JTextField, where the JTextField is populated by what is selected in the tree. When the user changes the text field, on focus lost, you update the tree from the text field. however, the tree selection is changed before the focus is lost on the text field. this is incorrect, right? Any ideas? Here is some sample code: import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.event.*; public class Focus extends JFrame { public static void main(String[] args) { Focus f = new Focus(); f.setLocationRelativeTo(null); f.setVisible(true); } public Focus() { Container cp = getContentPane(); cp.setLayout(new BorderLayout()); final JTextArea ta = new JTextArea(5, 10); cp.add(new JScrollPane(ta), BorderLayout.SOUTH); JSplitPane sp = new JSplitPane(); cp.add(sp, BorderLayout.CENTER); JTree t = new JTree(); t.addTreeSelectionListener(new TreeSelectionListener() { public void valueChanged(TreeSelectionEvent tse) { ta.append("Tree Selection changed\n"); } }); t.addFocusListener(new FocusListener() { public void focusGained(FocusEvent fe) { ta.append("Tree focus gained\n"); } public void focusLost(FocusEvent fe) { ta.append("Tree focus lost\n"); } }); sp.setLeftComponent(new JScrollPane(t)); JTextField f = new JTextField(10); sp.setRightComponent(f); pack(); f.addFocusListener(new FocusListener() { public void focusGained(FocusEvent fe) { ta.append("Text field focus gained\n"); } public void focusLost(FocusEvent fe) { ta.append("Text field focus lost\n"); } }); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }

• Issue with getting 2 chars from string using indexer

  - by Learner

  I am facing an issue in reading char values. See my program below. I want to evaluate an infix expression. As you can see I want to read '10' , '*', '20' and then use them...but if I use string indexer s[0] will be '1' and not '10' and hence I am not able to get the expected result. Can you guys suggest me something? Code is in c# class Program { static void Main(string[] args) { string infix = "10*2+20-20+3"; float result = EvaluateInfix(infix); Console.WriteLine(result); Console.ReadKey(); } public static float EvaluateInfix(string s) { Stack<float> operand = new Stack<float>(); Stack<char> operator1 = new Stack<char>(); int len = s.Length; for (int i = 0; i < len; i++) { if (isOperator(s[i])) // I am having an issue here as s[i] gives each character and I want the number 10 operator1.Push(s[i]); else { operand.Push(s[i]); if (operand.Count == 2) Compute(operand, operator1); } } return operand.Pop(); } public static void Compute(Stack<float> operand, Stack<char> operator1) { float operand1 = operand.Pop(); float operand2 = operand.Pop(); char op = operator1.Pop(); if (op == '+') operand.Push(operand1 + operand2); else if(op=='-') operand.Push(operand1 - operand2); else if(op=='*') operand.Push(operand1 * operand2); else if(op=='/') operand.Push(operand1 / operand2); } public static bool isOperator(char c) { bool result = false; if (c == '+' || c == '-' || c == '*' || c == '/') result = true; return result; } } }

• Unit Testing in the real world

  - by Malfist

  I manage a rather large application (50k+ lines of code) by myself, and it manages some rather critical business actions. To describe the program simple, I would say it's a fancy UI with the ability to display and change data from the database, and it's managing around 1,000 rental units, and about 3k tenants and all the finances. When I make changes, because it's so large of a code base, I sometimes break something somewhere else. I typically test it by going though the stuff I changed at the functional level (i.e. I run the program and work through the UI), but I can't test for every situation. That is why I want to get started with unit testing. However, this isn't a true, three tier program with a database tier, a business tier, and a UI tier. A lot of the business logic is performed in the UI classes, and many things are done on events. To complicate things, everything is database driven, and I've not seen (so far) good suggestions on how to unit test database interactions. How would be a good way to get started with unit testing for this application. Keep in mind. I've never done unit testing or TDD before. Should I rewrite it to remove the business logic from the UI classes (a lot of work)? Or is there a better way?

• Setting EditText imeOptions to actionNext has no effect

  - by Katedral Pillon

  I have a fairly complex (not really) xml layout file. One of the views is a LinearLayout (v1) with two children: an EditText(v2) and another LinearLayout(v3). The child LinearLayout in turn has an EditText(v4) and an ImageView(v5). For EditText v2 I have imeOptions as android:imeOptions="actionNext" But when I run the app, the keyboard's return does not check to next and I want it to change to next. How do I fix this problem? Also, when user clicks next, I want focus to go to EditText v4. I do I do this? For those who really need to see some code: <LinearLayout android:id="@+id/do_txt_view" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/col6" android:orientation="vertical" android:visibility="gone" > <EditText android:id="@+id/gm_title" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_margin="5dp" android:background="@drawable/coldo_text" android:hint="@string/enter_title" android:maxLines="1" android:imeOptions="actionNext" android:padding="5dp" android:textColor="pigc7" android:textSize="ads2" /> <LinearLayout android:layout_width="match_parent" android:layout_height="100dp" android:orientation="horizontal" > <EditText android:id="@+id/rev_text" android:layout_width="0dp" android:layout_height="match_parent" android:layout_gravity="center_vertical" android:layout_margin="5dp" android:layout_weight="1" android:background="@drawable/coldo_text" android:hint="@string/enter_msg" android:maxLines="2" android:padding="5dp" android:textColor="pigc7" android:textSize="ads2" /> <ImageView android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="center_vertical" android:background="@drawable/colbtn_r” android:clickable="true" android:onClick=“clickAct” android:paddingLeft="5dp" android:paddingRight="5dp" android:src="@drawable/abcat” /> </LinearLayout> </LinearLayout>

• Swing - how to mix JTextField and JTextAreas and have same visual appearance?

  - by I82Much

  I am using miglayout to create a form in which there are JTextFields (short input answers) as well as JTextAreas (Longer answers). The problem is twofold. The border placed around a Scrollpane wrapped text area does not match that of a Text Field. The width and placement of the textarea/textfield differ, causing them not to line up correctly. Source code: package test2; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTextArea; import javax.swing.JTextField; import net.miginfocom.swing.MigLayout; public class Test extends JPanel { private static final int NUM_CHARACTERS_WIDTH = 20; private static final int NUM_ROWS = 5; public Test() { setLayout(new MigLayout( "wrap 2", // Align text labels on the so their right edge meets left edge of the text fields "[right][left]" )); add(new JLabel("Text field:")); add(new JTextField(NUM_CHARACTERS_WIDTH)); add(new JLabel("No scrollpane text area:")); add(new JTextArea(NUM_ROWS, NUM_CHARACTERS_WIDTH)); add(new JLabel("Scrollpane text area:")); add(new JScrollPane(new JTextArea(NUM_ROWS, NUM_CHARACTERS_WIDTH))); add(new JLabel("Text field:")); add(new JTextField(NUM_CHARACTERS_WIDTH)); } public static void main(String[] args) { JFrame frame = new JFrame(""); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel panel = new Test(); frame.add(panel); frame.pack(); frame.setVisible(true); } } What's the preferred way to mix and match jtextfield and jtextareas, while still maintaining visual harmony? I notice now that the text field has a blue highlight around it when focus is in it, as opposed to the text area... another source of visual discontinuity.

• php string versus boolean speed test

  - by ae

  I'm looking at trying to optimise a particular function in a php app and foolishly assumed that a boolean lookup in a 'if' statement would be quicker than a string compare. But to check it I put together a short test (see below). To my surprise, the string lookup was quicker. Is there anything wrong with my test (I'm wired on too much coffee so I'm suspicious of my own code)? If not, I would be interested in any comments people have around string versus boolean lookups in php. The result for the first test (boolean lookup) was 0.168 The result for the second test (string lookup) was 0.005 <?php $how_many = 1000000; $counter1 = 0; $counter2 = 0; $abc = array('boolean_lookup'=>TRUE, 'string_lookup'=>'something_else'); $start = microtime(); for($i = 0; $i < $how_many; $i++) { if($abc['boolean_lookup']) { $counter1++; } } echo ($start - microtime()); echo '<hr>'; $start = microtime(); for($i = 0; $i < $how_many; $i++) { if($abc['string_lookup'] == 'something_else') { $counter2++; } } echo ($start - microtime());

• flash as3 document class and event listeners

  - by Lee

  I think i have this document class concept entirly wrong now, i was wondering if someone mind explaining it.. I assumed that the above class would be instantiated within the first frame on scene one of a movie. I also assumed that when changing scenes the state of the class would remain constant so any event listeners would still be running.. Scene 1: I have a movieclip named ui_mc, that has a button in for muting sound. Scene 2: I have the same movie clip with the same button. Now the eventListener picks it up in the first scene, however it does not in the second. I am wondering for every scene do the event listeners need to be resetup? If that is the case if their an event listener to listen for the change in scene, so i can set them back up again lol.. Thanks in advance.. package { import flash.display.MovieClip; import flash.events.MouseEvent; import flash.media.Sound; import flash.media.SoundChannel; public class game extends MovieClip { public var snd_state:Boolean = true; public function game() { ui_setup(); } public function ui_setup():void { ui_mc.toggleMute_mc.addEventListener(MouseEvent.CLICK, snd_toggle); } private function snd_toggle(event:MouseEvent):void { // 0 = No Sound, 1 = Full Sound trace("Toggle"); } } }

• R plot- SGAM plot counts vs. time - how do I get dates on the x-axis?

  - by Nate

  I'd like to plot this vs. time, with the actual dates (years actually, 1997,1998...2010). The dates are in a raw format, ala SAS, days since 1960 (hence as.date conversion). If I convert the dates using as.date to variable x, and do the GAM plot, I get an error. It works fine with the raw day numbers. But I want the plot to display the years (data are not equally spaced). structure(list(site = c(928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L), date = c(13493L, 13534L, 13566L, 13611L, 13723L, 13752L, 13804L, 13837L, 13927L, 14028L, 14082L, 14122L, 14150L, 14182L, 14199L, 16198L, 16279L, 16607L, 16945L, 17545L, 17650L, 17743L, 17868L, 17941L, 18017L, 18092L), y = c(7L, 7L, 17L, 18L, 17L, 17L, 10L, 3L, 17L, 24L, 11L, 5L, 5L, 3L, 5L, 14L, 2L, 9L, 9L, 4L, 7L, 6L, 1L, 0L, 5L, 0L)), .Names = c("site", "date", "y"), class = "data.frame", row.names = c(NA, -26L)) sgam1 <- gam(sites$y ~ s(sites$date)) sgam <- predict(sgam1, se=TRUE) plot(sites$date,sites$y,xaxt="n", xlab='Time', ylab='Counts') x<-as.Date(sites$date, origin="1960-01-01") axis(1, at=1:26,labels=x) lines(sites$date,sgam$fit, lty = 1) lines(sites$date,sgam$fit + 1.96* sgam$se, lty = 2) lines(sites$date,sgam$fit - 1.96* sgam$se, lty = 2) ggplot2 has a solution (it doesn't mind the as.date thing) but it gives me other problems...

  I have the following schema: <?xml version="1.0"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:tipos="http://www.ginfes.com.br/tipos_v03.xsd" targetNamespace="http://www.ginfes.com.br/servico_consultar_situacao_lote_rps_resposta_v03.xsd" xmlns="http://www.ginfes.com.br/servico_consultar_situacao_lote_rps_resposta_v03.xsd" attributeFormDefault="unqualified" elementFormDefault="qualified"> <xsd:import schemaLocation="tipos_v03.xsd" namespace="http://www.ginfes.com.br/tipos_v03.xsd" /> <xsd:element name="ConsultarSituacaoLoteRpsResposta"> <xsd:complexType> <xsd:choice> <xsd:sequence> <xsd:element name="NumeroLote" type="tipos:tsNumeroLote" minOccurs="1" maxOccurs="1"/> <xsd:element name="Situacao" type="tipos:tsSituacaoLoteRps" minOccurs="1" maxOccurs="1"/> </xsd:sequence> <xsd:element ref="tipos:ListaMensagemRetorno" minOccurs="1" maxOccurs="1"/> </xsd:choice> </xsd:complexType> </xsd:element> </xsd:schema> and the following class: [System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "2.0.50727.3038")] [System.SerializableAttribute()] [System.Diagnostics.DebuggerStepThroughAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://www.ginfes.com.br/servico_consultar_situacao_lote_rps_envio_v03.xsd")] [System.Xml.Serialization.XmlRootAttribute(Namespace = "http://www.ginfes.com.br/servico_consultar_situacao_lote_rps_envio_v03.xsd", IsNullable = false)] public partial class ConsultarSituacaoLoteRpsEnvio { [System.Xml.Serialization.XmlElementAttribute(Order = 0)] public tcIdentificacaoPrestador Prestador { get; set; } [System.Xml.Serialization.XmlElementAttribute(Order = 1)] public string Protocolo { get; set; } } Use the following code to deserialize the object: XmlSerializer respSerializer = new XmlSerializer(typeof(ConsultarSituacaoLoteRpsResposta)); StringReader reader = new StringReader(resp); ConsultarSituacaoLoteRpsResposta respModel = (ConsultarSituacaoLoteRpsResposta)respSerializer.Deserialize(reader); does not occur any error but the properties of objects are null, anyone know what is happening?

• zend_captcha always fails isValid()

  - by Grant Collins

  Hi, I've got an issue with Zend_Captcha always returning false when the page is submitted and the captcha's isValid() method is being called. It's driving my nuts because this as far as I am concerned should work. I start by declaring this at the top of the action function of the controller $captcha = new Zend_Captcha_Image('captcha', array( 'captcha' => array( 'name' => 'graduatesignupcaptcha', 'wordlen' => 6, 'font' => $this->config->captcha->font, 'imgDir' => $baseUrl.'/images/captcha/', 'imgUrl' => $this->config->webserver->name.'/images/captcha/', ) ) ); $captcha->setHeight(80) ->setTimeout(300); I do usual form validation and that all works, however it is when I come to validate that the value entered into form for the captcha it always returns false. //next we check the captcha text to ensure that the form is a person not a script $captchaText = $form->getElement('captchainput')->getValue(); $captchaId = $form->getElement('captchaid')->getValue(); //$captchaSession = new Zend_Session_Namespace('Zend_Form_Captcha_'.$captchaId); $captchaArray = array( 'id' => $captchaId, 'input' => $captchaText ); if(!$captcha->isValid($captchaArray)){ $log->log(implode(",",$captcha->getErrors()), Zend_Log::DEBUG); $form->getElement('captchainput')->setErrors(array('messages' => 'Bad security code')); $formFailed = true; } I've check to ensure that the id that I am getting and storing as a hidden element in my form match the image that is being generated but no matter what I do this always fails. Am I missing something simple here?? Or is there a better way of dealing with this?? Thanks,

• JS encodeURIComponent result different from the one created by FORM

  - by Marco Demaio

  I thought values entered in forms are properly encoded by browsers. But this simple test shows it's not true: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head> <meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> <title></title> </head><body> <form id="test" action="test_get_vs_encodeuri.html" method="GET" onsubmit="alert(encodeURIComponent(this.one.value));"> <input name="one" type="text" value="Euro-€"> <input type="submit" value="SUBMIT"> </form> </body></html> When hitting submit button: encodeURICompenent encodes input value into "Euro-%E2%82%AC" while browser into the GET query writes only a simple "Euro-%80" Could somone explain? Or is encodeURIComponent doing unnecessary conversions?

  - by sergiogx

  Im having trouble with a stored procedure, I can't commit after I execute it. Its showing this error "[System.Data.Odbc.OdbcException] = {"ERROR [HY000] [MySQL][ODBC 5.1 Driver]Commands out of sync; you can't run this command now"}" The SP by itself works fine. does anyone have idea of what might be happening? .net code: [WebMethod()] [SoapHeader("sesion")] public Boolean aceptarTasaCero(int idMunicipio, double valor) { Boolean resultado = false; OdbcConnection cxn = new OdbcConnection(); cxn.ConnectionString = ConfigurationManager.ConnectionStrings["mysqlConnection"].ConnectionString; cxn.Open(); OdbcCommand cmd = new OdbcCommand("call aceptarTasaCero(?,?)", cxn); cmd.Parameters.Add("idMunicipio", OdbcType.Int).Value = idMunicipio; cmd.Parameters.Add("valor", OdbcType.Double).Value = valor; cmd.Transaction = cxn.BeginTransaction(); try { OdbcDataReader dr = cmd.ExecuteReader(); if (dr.Read()) { resultado = Convert.ToBoolean(dr[0]); } cmd.Transaction.Commit(); } catch (Exception ex) { ExBi.log(ex, sesion.idUsuario); cmd.Transaction.Rollback(); } finally { cxn.Close(); } return resultado; } and this is the code for the stored procedure DELIMITER $$ DROP PROCEDURE IF EXISTS `aceptartasacero` $$ CREATE DEFINER=`database`@`%` PROCEDURE `aceptartasacero`(pidMun INTEGER, pvalor double) BEGIN declare vExito BOOLEAN; INSERT INTO tasacero(anio,valor,idmunicipios) VALUES(YEAR(curdate()),pValor,pidMun); set vExito = true; select vExito; END $$ DELIMITER ; thanks.

• Help me re-center a ModalPopup within an iframe when the iframe's parent window scrolls

  - by Cory Larson

  I have a web page with an iframe in it (I don't like it, but that's the way it has to be). It's not a cross-domain iframe so there's nothing to worry about there. I have written a jQuery extension that does the centering of a ModalPopup (which is called from an overridden AjaxControlToolkit.ModalPopupBehavior._layout method) based on the width and height of the iframe's parent, so that it looks centered even though the iframe is not in the center of the page. It's a lot of tricky stuff, especially since the web page I added the iframe to runs in quirks mode. Now, I've also overridden AjaxControlToolkit.ModalPopupBehavior._attachPopup, so that when the parent window resizes or scrolls, the ModalPopup inside of the iframe recenter's itself relative to the new size of the parent window. However, the same code that attaches the popup to the parent window's resize event does NOT work for the parent window's scroll event. See the code below, and the comments: AjaxControlToolkit.ModalPopupBehavior.prototype._attachPopup = function() { /// <summary> /// Attach the event handlers for the popup to the PARENT window /// </summary> if (this._DropShadow && !this._dropShadowBehavior) { this._dropShadowBehavior = $create(AjaxControlToolkit.DropShadowBehavior, {}, null, null, this._popupElement); } if (this._dragHandleElement && !this._dragBehavior) { this._dragBehavior = $create(AjaxControlToolkit.FloatingBehavior, {"handle" : this._dragHandleElement}, null, null, this._foregroundElement); } $addHandler(parent.window, 'resize', this._resizeHandler); // <== This WORKS $addHandler(parent.window, 'scroll', this._scrollHandler); // <== This DOES NOT work this._windowHandlersAttached = true; } Can anybody explain to me why the resize event works while the scroll event doesn't? Any suggestions or alternatives out there to help me out? I am working with jQuery, so if I can use something besides the $addHandler method from MS that'd be fine. Be aware that I also have to override the _detachPopup function to remove the handler, so I need to take that into account. Thanks!
