  • A little bit of Ajax goes a long way

    - by Holland
    ..except when you're having problems. My problem is this: I have a hierarchical list of categories stored in a database which I wish to output in a dropdown list. The hierarchy comes into place when the subcategories are to be displayed, which are dependent on a parent id (which equals out to the first seven or so main categories listed). My thoughts are relatively simple: when the user clicks the dynamically allocated list of main categories, they are clicking on an option tag. For each option tag, an id (i.e., the parent) is listed in the value attribute, as well as an argument which is sent to a Javascript function which then uses AJAX to get the data via PHP and sends it to my 'javascript.php' file. The file then does magic, and populates the subcategory list, which is dependent on the main category selected. I believe I have the idea down, it's just that I'm implementing the solution improperly, for some reason. Here's what I have so far: from javascript.php <script type="text/javascript" src=<?=JPATH_BASE.DS.'includes'.DS.'jquery.js';?>> var ajax = { ajax.sendAjaxData = function(method, url, dataTitle, ajaxData) { $.ajax({ type: 'post', url: "C:/wamp/www/patention/components/com_adsmanagar/views/edit/tmpl/javascript.php", data: { 'data' : ajaxData }, success: function(result){ // we have the response alert("Your request was successful." + result); }, error: function(e){ alert('Error: ' + e); } }); } ajax.printSubCategoriesOnClick = function(parent) { alert("hello world!"); ajax.sendAjaxData('post', 'javascript.php', 'data' parent); <?php $categories = $this->formData->getCategories($_POST['data']); ?> ajax.printSubCategories(<?=$categories;?>); } ajax.printSubCategories = function(categories) { var select = document.getElementById("subcategories"); for (var i = 0; i < categories.length; i++) { var opt = document.createElement("option"); opt.text = categories['name']; opt.value = categories['id']; } } } </script> the function used to populate the form data function populateCategories($parent, FormData $formData) { $categories = $formData->getCategories($parent); echo "<pre>"; print_r($categories); echo "</pre>"; foreach($categories as $section => $row){ ?> <option value=<?=$row['id'];?> onclick="ajax.printSubCategoriesOnClick(<?=$row['id']?>)"> <? echo $row['name']; ?> </option> <?php } } The problem is that when I try to do a print_r on my $_POST variable, nothing shows up. I also receive an "undefined index" error (which refers to the key I set for the data type). I'm thinking that for some reason, the data is being sent to my form.php file, or my default.php file which includes both the form.php and javascript.php files via a function. Is there something specific that I'm missing here? Just looking up basic AJAX syntax (via jQuery) hasn't helped out, unfortunately.

  • Windows 7 client can't connect to CentOS PPTP VPN

    - by Chris
    Have a Macintosh (10.8.2) that connects just fine to a CentOS 6.0 virtual private server (OpenVZ, with PPP added by the host) via PPTP. A Windows 7 Home Premium client (virtualized in Sun's Virtual Box), on the same computer, using the same Ethernet connection, cannot connect to the Linux VPN server. I have iptables disabled (for testing) on the Linux box. I have the Windows firewall turned off. /var/log/messages looks like this, for a Windows connection: Oct 12 18:44:30 production pptpd[1880]: CTRL: Client 66.104.246.168 control connection started Oct 12 18:44:30 production pptpd[1880]: CTRL: Starting call (launching pppd, opening GRE) Oct 12 18:44:30 production pppd[1881]: Plugin /usr/lib/pptpd/pptpd-logwtmp.so loaded.

  • Update twitter profile image using OAuth

    - by sjobe
    I'm trying to get twitter update_profile_image to work using OAuth. I was using curl with regular authentication and everything was working fine, but I switched to OAuth using this library, and now everything except update_profile_image works. I read something about twitter OAuth having problems with multipart data, but that was a while ago and the plugin is supposed to have dealt with that issue. My working regular authentication with curl code $url = 'http://api.twitter.com/1/account/update_profile_image.xml'; $uname = $_POST['username']; $pword = $_POST['password']; $img_path = 'xxx'; $userpwd = $uname . ':' . $pword; $img_post = array('image' => '@' . $img_path . ';type=image/jpeg', 'tile' => 'true'); $format = 'xml'; //alternative: json $message = 'Test update with a random num'.rand(); $opts = array(CURLOPT_URL => $url, CURLOPT_FOLLOWLOCATION => true, CURLOPT_RETURNTRANSFER => true, CURLOPT_HEADER => true, CURLOPT_POST => true, CURLOPT_POSTFIELDS => $img_post, CURLOPT_HTTPAUTH => CURLAUTH_ANY, CURLOPT_USERPWD => $userpwd, CURLOPT_HTTPHEADER => array('Expect:'), CURLINFO_HEADER_OUT => true); $ch = curl_init(); curl_setopt_array($ch, $opts); $response = curl_exec($ch); $err = curl_error($ch); $info = curl_getinfo($ch); curl_close($ch); My current OAuth code [I had to cut it down, so do not minor look for syntax errors] include 'EpiCurl.php'; include 'EpiOAuth.php'; include 'EpiTwitter.php'; include 'secret.php'; $twitterObj = new EpiTwitter($consumer_key, $consumer_secret); $twitterObj->setToken($_GET['oauth_token']); $token = $twitterObj->getAccessToken(); $twitterObj->setToken($token->oauth_token, $token->oauth_token_secret); try{ $img_path = 'xxx'; //$twitterObj->post_accountUpdate_profile_image(array('@image' => "@".$img_path)); $twitterObj->post('/account/update_profile_image.json', array('@image' => "@".$img_path)); $twitterObj->post_statusesUpdate(array('status' => 'This is my new status:'.rand())); //This works $twitterInfo= $twitterObj->get_accountVerify_credentials(); echo $twitterInfo->responseText; }catch(Exception $e){ echo $e->getMessage(); } I've been trying to figure this out for a while, ANY help would be greatly appreciated. I'm not in any way tied to this library, so feel free to recommend others.

  • Why C# doesn't implement indexed properties ?

    - by Thomas Levesque
    I know, I know... Eric Lippert's answer to this kind of question is usually something like "because it wasn't worth the cost of designing, implementing, testing and documenting it". But still, I'd like a better explanation... I was reading this blog post about new C# 4 features, and in the section about COM Interop, the following part caught my attention : By the way, this code uses one more new feature: indexed properties (take a closer look at those square brackets after Range.) But this feature is available only for COM interop; you cannot create your own indexed properties in C# 4.0. OK, but why ? I already knew and regretted that it wasn't possible to create indexed properties in C#, but this sentence made me think again about it. I can see several good reasons to implement it : the CLR supports it (for instance, PropertyInfo.GetValue has an index parameter), so it's a pity we can't take advantage of it in C# it is supported for COM interop, as shown in the article (using dynamic dispatch) it is implemented in VB.NET it is already possible to create indexers, i.e. to apply an index to the object itself, so it would probably be no big deal to extend the idea to properties, keeping the same syntax and just replacing this with a property name It would allow to write that kind of things : public class Foo { private string[] _values = new string[3]; public string Values[int index] { get { return _values[index]; } set { _values[index] = value; } } } Currently the only workaround that I know is to create an inner class (ValuesCollection for instance) that implements an indexer, and change the Values property so that it returns an instance of that inner class. This is very easy to do, but annoying... So perhaps the compiler could do it for us ! An option would be to generate an inner class that implements the indexer, and expose it through a public generic interface : // interface defined in the namespace System public interface IIndexer<TIndex, TValue> { TValue this[TIndex index] { get; set; } } public class Foo { private string[] _values = new string[3]; private class <>c__DisplayClass1 : IIndexer<int, string> { private Foo _foo; public <>c__DisplayClass1(Foo foo) { _foo = foo; } public string this[int index] { get { return _foo._values[index]; } set { _foo._values[index] = value; } } } private IIndexer<int, string> <>f__valuesIndexer; public IIndexer<int, string> Values { get { if (<>f__valuesIndexer == null) <>f__valuesIndexer = new <>c__DisplayClass1(this); return <>f__valuesIndexer; } } } But of course, in that case the property would actually return a IIndexer<int, string>, and wouldn't really be an indexed property... It would be better to generate a real CLR indexed property. What do you think ? Would you like to see this feature in C# ? If not, why ?

  • Configuring hibernate.reveng.xml to detect a sequence PK generator with hibernate3-maven-plugin and

    - by mmm
    Hi, is there a way to configure hibernate3-maven-plugin so that a sequence generator is detected for a primary-key? I'm using a bottom-up approach for hibernate configuration (which means letting hibernate-tools generate the hibernate configuration using a jdbc-connection for you via reverse-engineering on an existing database schema). I've read this, but also this already (those two can be unrelated, but can also leave a hint). My hibernate.reveng.xml is the following: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-reverse-engineering SYSTEM "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" > <hibernate-reverse-engineering> <table name="ORDERS"> <primary-key> <!-- setting up a specific id generator for a table --> <generator class="sequence"> <param name="sequence">ORDERS_ORDER_ID_seq</param> </generator> <key-column name="ORDER_ID"/> </primary-key> </table> </hibernate-reverse-engineering> And I'm expecting it to generate an Orders.hbm.xml file like this: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated 2010-06-06 18:55:42 by Hibernate Tools 3.2.2.GA --> <hibernate-mapping> <class name="some.package.Orders" table="orders" schema="public"> <id name="orderId" type="long"> <column name="order_id" /> <generator class="sequence"> <param name="sequence">ORDERS_ORDER_ID_seq</param> </generator> </id> ... </class> </hibernate-mapping> ...but receiving this instead: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated 2010-06-06 18:55:42 by Hibernate Tools 3.2.2.GA --> <hibernate-mapping> <class name="some.package.Orders" table="orders" schema="public"> <id name="orderId" type="long"> <column name="order_id" /> <generator class="assigned" /> </id> ... </class> </hibernate-mapping> I know my hibernate.reveng.xml is being read by hibernate3-maven-plugin, as I experience maven errors whenever syntax errors appear in the file, so pom.xml seems to be correct and hibernate.reveng.xml syntactically correct. Any clues?

  • Silverlight: how to modify the width of ListBox Items in response to user input?

    - by sympatric greg
    I have a simple Silverlight 3 UserControl whose width increases or decreases based on user input. The controls become more wide or more narrow as desired, except for the ListBox items. The ListBox Items grow horizontally to fit their content regardless of HorizontalContentAlignment being set to 'Stretch'. Should I be able to set a property on ListBox.ItemContainerStyle to tell it to widen/narrow with the parent ListBox? There needs to be no horizontal scrolling within this Listbox. Or is there a way to specify the ItemTemplate's StackPanel width that can be modified at runtime? I have bound this to a StaticResource, but do not understand whether I should be able to change the resource value. Can I create and bind to a DependencyProperty of the UserControl itself? I have not determined the syntax of this within the xaml. code: <UserControl x:Class="TheAssembly.GraphicViewer" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:userControls="clr-namespace:TheAssembly" xmlns:core="clr-namespace:System;assembly=mscorlib"> <UserControl.Resources> <userControls:DictionaryAttributeConverter x:Name="MyDictionaryAttributeConverter" /> <core:Double x:Key="ListItemWidth">155</core:Double> </UserControl.Resources> <Grid x:Name="LayoutRoot" Width="175" > <Border Style="{StaticResource DraggableWindowBorder}"> <StackPanel x:Name="RootStackPanel" Orientation="Vertical" HorizontalAlignment="Stretch"> <Border Background="Black" HorizontalAlignment="Stretch" Margin="0"> <TextBlock x:Name="Header" Foreground="White" FontSize="14" TextWrapping="Wrap" Margin="2,0,2,0" Height="25" HorizontalAlignment="Left" Text="{Binding HeaderText}"/> </Border> <TextBlock x:Name="Title" Style="{StaticResource GraphicViewerDetail}" FontSize="12" FontWeight="Medium" TextWrapping="Wrap" Text="{Binding Title}" Margin="3,0,0,0" HorizontalAlignment="Left"/> <ListBox x:Name="AttributeListBox" ItemsSource="{Binding Attributes}" BorderBrush="Red" HorizontalContentAlignment="Stretch" Foreground="AntiqueWhite" Background="Transparent" IsEnabled="False" HorizontalAlignment="Stretch" ScrollViewer.VerticalScrollBarVisibility="Visible" ScrollViewer.HorizontalScrollBarVisibility="Hidden"> <ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Setter Property="HorizontalAlignment" Value="Stretch"/> <Setter Property="HorizontalContentAlignment" Value="Stretch"/> <Setter Property="Margin" Value="0,-2,0,0"/> </Style> </ListBox.ItemContainerStyle> <ListBox.ItemTemplate> <DataTemplate> <StackPanel x:Name="ListBoxItemStackPanel" HorizontalAlignment="Stretch" Orientation="Vertical" > <TextBlock FontSize="10" Text="{Binding Key}" Foreground="White" FontWeight="Bold" HorizontalAlignment="Stretch" Margin="2,0,0,0" TextWrapping="Wrap"/> <TextBlock FontSize="10" Text="{Binding Value}" Foreground="White" Margin="6,-2,0,0" TextWrapping="Wrap" HorizontalAlignment="Stretch" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </StackPanel> </Border> </Grid>

  • Is possible to make mt.exe embed manifest files correctly in Visual Studio 2008?

    - by Sorin Sbarnea
    I found that mt.exe fails to correctly create and embed manifest files into executables when run inside a VCPROJ. For example the same executable load well on Windows 7 but failed to load on Windows XP. The manifest was embedded and correct. After I spend lots of hours searching for possible reasons and solution I modified the project settings to generate the manifest outside the exe file. Now it works on both systems. Here are the examples for debug builds. With embed disabled: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3"> <security> <requestedPrivileges> <requestedExecutionLevel level="asInvoker" uiAccess="false"></requestedExecutionLevel> </requestedPrivileges> </security> </trustInfo> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.VC90.DebugCRT" version="9.0.21022.8" processorArchitecture="x86" publicKeyToken="1fc8b3b9a1e18e3b"></assemblyIdentity> </dependentAssembly> </dependency> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.VC90.DebugMFC" version="9.0.21022.8" processorArchitecture="x86" publicKeyToken="1fc8b3b9a1e18e3b"></assemblyIdentity> </dependentAssembly> </dependency> </assembly> This is with embed enabled: <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3"> <security> <requestedPrivileges> <requestedExecutionLevel level="asInvoker" uiAccess="false" /> </requestedPrivileges> </security> </trustInfo> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.VC90.DebugCRT" version="9.0.21022.8" processorArchitecture="x86" publicKeyToken="1fc8b3b9a1e18e3b" /> </dependentAssembly> </dependency> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.VC90.DebugMFC" version="9.0.21022.8" processorArchitecture="x86" publicKeyToken="1fc8b3b9a1e18e3b" /> </dependentAssembly> </dependency> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="x86" publicKeyToken="6595b64144ccf1df" language="*" /> </dependentAssembly> </dependency> </assembly> If you compare them the second one adds common controls (I don't know from where) and also it is a small difference with the syntax of requestedExecutionLevel tag.

  • How to echo if field is not found?

    - by Fahad
    Hi I'm trying to figure out how to echo back if the value entered does not match when a database lookup is done. I'm using ajax to run the request and php to do the lookup ajax.js: function showResult(str) { if (str=="") { document.getElementById("description").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("description").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","getuser.php?voucher="+str,true); xmlhttp.send(null); } and getuser.php: <?php $q=$_GET["voucher"]; $con = mysql_connect('localhost', 'root', ''); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("test", $con); $sql="SELECT * FROM redemption WHERE voucher = '".$q."'"; $result = mysql_query($sql); echo "<table> <tr> <th>Name</th> <th>Product</th> <th>Address</th> <th>Status</th> </tr>"; while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['name'] . "</td>"; echo "<td>" . $row['product'] . "</td>"; echo "<td>" . $row['address'] ." ".$row['city'] ." ".$row['province'] ." ".$row['postal'] . "</td>"; echo "<td>" . $row['status'] . "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($con); ?> What I would like to do is that once the person enters an invalid or a voucher number that is not found I would like to return an error that "Voucher number is not found". There is also a column in the db that stores the status such as "redeemed" or "not redeemed". How could I check for both whether the voucher number exists and if it has already been redeemed? I assume it'd have to be a syntax such as $sql="SELECT * FROM redemption WHERE voucher = '".$q."'" AND status = 'not redeemed' and then use an else or case statement perhaps? Thanks in advance

  • Running 32 bit assembly code on a 64 bit Linux & 64 bit Processor : Explain the anomaly.

    - by claws
    Hello, I'm in an interesting problem.I forgot I'm using 64bit machine & OS and wrote a 32 bit assembly code. I don't know how to write 64 bit code. This is the x86 32-bit assembly code for Gnu Assembler (AT&T syntax) on Linux. //hello.S #include <asm/unistd.h> #include <syscall.h> #define STDOUT 1 .data hellostr: .ascii "hello wolrd\n"; helloend: .text .globl _start _start: movl $(SYS_write) , %eax //ssize_t write(int fd, const void *buf, size_t count); movl $(STDOUT) , %ebx movl $hellostr , %ecx movl $(helloend-hellostr) , %edx int $0x80 movl $(SYS_exit), %eax //void _exit(int status); xorl %ebx, %ebx int $0x80 ret Now, This code should run fine on a 32bit processor & 32 bit OS right? As we know 64 bit processors are backward compatible with 32 bit processors. So, that also wouldn't be a problem. The problem arises because of differences in system calls & call mechanism in 64-bit OS & 32-bit OS. I don't know why but they changed the system call numbers between 32-bit linux & 64-bit linux. asm/unistd_32.h defines: #define __NR_write 4 #define __NR_exit 1 asm/unistd_64.h defines: #define __NR_write 1 #define __NR_exit 60 Anyway using Macros instead of direct numbers is paid off. Its ensuring correct system call numbers. when I assemble & link & run the program. $cpp hello.S hello.s //pre-processor $as hello.s -o hello.o //assemble $ld hello.o // linker : converting relocatable to executable Its not printing helloworld. In gdb its showing: Program exited with code 01. I don't know how to debug in gdb. using tutorial I tried to debug it and execute instruction by instruction checking registers at each step. its always showing me "program exited with 01". It would be great if some on could show me how to debug this. (gdb) break _start Note: breakpoint -10 also set at pc 0x4000b0. Breakpoint 8 at 0x4000b0 (gdb) start Function "main" not defined.

This is its output: execve("./helloworld", ["./helloworld"], [/* 39 vars */]) = 0 write(0, NULL, 12 <unfinished ... exit status 1> Explain the parameters of write(0, NULL, 12) system call in the output of strace? What exactly is happening? I want to know the reason why exactly its exiting with exitstatus=1? Can some one please show me how to debug this program using gdb? Why did they change the system call numbers? Kindly change this program appropriately so that it can run correctly on this machine. EDIT: After reading Paul R's answer.

What exactly is happening in this case? Can someone please answer my questions and provide an x86-64 version of this code?

  • Python/numpy tricky slicing problem

    - by daver
    Hi stack overflow, I have a problem with some numpy stuff. I need a numpy array to behave in an unusual manner by returning a slice as a view of the data I have sliced, not a copy. So heres an example of what I want to do: Say we have a simple array like this: a = array([1, 0, 0, 0]) I would like to update consecutive entries in the array (moving left to right) with the previous entry from the array, using syntax like this: a[1:] = a[0:3] This would get the following result: a = array([1, 1, 1, 1]) Or something like this: a[1:] = 2*a[:3] # a = [1,2,4,8] To illustrate further I want the following kind of behaviour: for i in range(len(a)): if i == 0 or i+1 == len(a): continue a[i+1] = a[i] Except I want the speed of numpy. The default behavior of numpy is to take a copy of the slice, so what I actually get is this: a = array([1, 1, 0, 0]) I already have this array as a subclass of the ndarray, so I can make further changes to it if need be, I just need the slice on the right hand side to be continually updated as it updates the slice on the left hand side. Am I dreaming or is this magic possible? Update: This is all because I am trying to use Gauss-Seidel iteration to solve a linear algebra problem, more or less. It is a special case involving harmonic functions, I was trying to avoid going into this because its really not necessary and likely to confuse things further, but here goes. The algorithm is this: while not converged: for i in range(len(u[:,0])): for j in range(len(u[0,:])): # skip over boundary entries, i,j == 0 or len(u) u[i,j] = 0.25*(u[i-1,j] + u[i+1,j] + u[i, j-1] + u[i,j+1]) Right? But you can do this two ways, Jacobi involves updating each element with its neighbours without considering updates you have already made until the while loop cycles, to do it in loops you would copy the array then update one array from the copied array. However Gauss-Seidel uses information you have already updated for each of the i-1 and j-1 entries, thus no need for a copy, the loop should essentially 'know' since the array has been re-evaluated after each single element update. That is to say, every time we call up an entry like u[i-1,j] or u[i,j-1] the information calculated in the previous loop will be there. I want to replace this slow and ugly nested loop situation with one nice clean line of code using numpy slicing: u[1:-1,1:-1] = 0.25(u[:-2,1:-1] + u[2:,1:-1] + u[1:-1,:-2] + u[1:-1,2:]) But the result is Jacobi iteration because when you take a slice: u[:,-2,1:-1] you copy the data, thus the slice is not aware of any updates made. Now numpy still loops right? Its not parallel its just a faster way to loop that looks like a parallel operation in python. I want to exploit this behaviour by sort of hacking numpy to return a pointer instead of a copy when I take a slice. Right? Then every time numpy loops, that slice will 'update' or really just replicate whatever happened in the update. To do this I need slices on both sides of the array to be pointers. Anyway if there is some really really clever person out there that awesome, but I've pretty much resigned myself to believing the only answer is to loop in C.

  • "interface not found" in WCF Moniker without registration for excel

    - by tbischel
    I'm trying to connect excel to a WCF service, but I can't seem to get even a trivial case to work... I get an Invalid Syntax error when I try and create the proxy in excel. I've attached the visual studio debugger to excel, and get that the real error is "interface not found". I know the service works because the test client created by visual studio is ok... so the problem is in the VBA moniker string. I'm hoping to find one of two things: 1) a correction to my moniker string that will make this work, or 2) an existing sample project to download that has the source for both the host and client that does work. Here is the code for my VBA client: Dim addr As String addr = "service:mexAddress=net.tcp://localhost:7891/Test/WcfService1/Service1/mex, " addr = addr + "address=net.tcp://localhost:7891/Test/WcfService1/Service1/, " addr = addr + "contract=IService1, contractNamespace=http://tempuri.org, " addr = addr + "binding=NetTcpBinding_IService1, bindingNamespace=""http://tempuri.org""" MsgBox (addr) Dim service1 As Object Set service1 = GetObject(addr) MsgBox service1.Test(12) I have the following service: [ServiceContract] public interface IService1 { [OperationContract] string GetData(int value); } public class Service1 : IService1 { public string GetData(int value) { return string.Format("You entered: {0}", value); } } It has the following config file: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.web> <compilation debug="true" /> </system.web> <!-- When deploying the service library project, the content of the config file must be added to the host's app.config file.

  • How do I evaluate my skillset against the current market to see what needs improvement and where my

    - by baijajusav
    First of all, this question may be out of bounds for this site. If so, remove it. I say this because this site seems to be a place for more concrete questions that are not so relative in nature. And before I begin, for those of you whom just prefer a question and not this sort of dialog, here is my question: How can I assess my current skills as a programmer and decide where and what areas to improve upon? That said, here's what I'm asking/talking about, in essence. The market is always in constant flux. As programmers we're always having to learn new things, update our skills, push ourselves into that next project. There's not a very good litmus test that I know of for us to get an idea of where we stand as programmers. I came across this blog post by Jeff Atwood talking about why can't programmers code. Instinctively (and as the post goes on to state) I rushed through the program in about 4 minutes (most of that time was b/c I was hand writing it out. Still, this doesn't really answer the question of where do my skills need to be to succeed in today's world. I real blogs, listen to podcasts, try to keep up on the latest things coming out. It has only been in the past couple of months that I made a decision to pick a focus area for my learning as I can't learn everything and trying to do so is to spread myself too thin. I chose ASP.NET MVC & C#. I plan to stick with Microsoft technologies, not out of some sense of loyalty or stubbornness, but rather because they seem to stream together and have a unifying connection between them. With Windows Phone 7 coming out, it seems that now is the obvious time to pick up WPF and Silverlight as well. Still, if you asked me to code something apart from intellisense and the internet, I probably couldn't get the syntax right. I don't have libraries memorized or know precisely where the classes I use exist within the .Net framework, namely because I haven't had to pull that knowledge out of the air. In a way, I suppose Visual Studio has insulated me, which isn't a good thing, but, at the same time, I've still been able to be productive. I'm working on my own side project to try and help my learning. In doing so, I'm trying to make use of best practices and 3rd party frameworks where I can. I'm using automapper and EF 1.0. I know everyone in the .net community seems to cry foul at the sound of EF 1.0, but I can't say why because I've never used it. There's no lazy loading and that has proven rather annoying; however, aside from that, I haven't had that much of an issue. Granted this is probably because I'm not writing tests as I go (which I'm not doing because I don't know how to test EF in tests and don't really have a clue how to write tests for ASP.NET MVC 1.0). I'm also using a custom membership provider; granted, it's a barebone implementation, but I'm using it still. My thinking in all of this is, while I am neglecting a great many important technologies that are in the mainstream, I'll have a working project in the end. I can come back and add those things after I finish. Doing it all now and at once seems like too much. I know how I work and I don't think I'd ever get it done that way. I've elected to make this a community wiki as I think this question might fight better there. If a moderator disagrees with that choice or the decision to post this here, the just delete the question. I'm not trying to make undue work for anyone. I'm just a programmer trying to assess my where his skills are now and where I should be improving.

  • Disable antialiasing for a specific GDI device context

    - by Jacob Stanley
    I'm using a third party library to render an image to a GDI DC and I need to ensure that any text is rendered without any smoothing/antialiasing so that I can convert the image to a predefined palette with indexed colors. The third party library i'm using for rendering doesn't support this and just renders text as per the current windows settings for font rendering. They've also said that it's unlikely they'll add the ability to switch anti-aliasing off any time soon. The best work around I've found so far is to call the third party library in this way (error handling and prior settings checks ommitted for brevity): private static void SetFontSmoothing(bool enabled) { int pv = 0; SystemParametersInfo(Spi.SetFontSmoothing, enabled ? 1 : 0, ref pv, Spif.None); } // snip Graphics graphics = Graphics.FromImage(bitmap) IntPtr deviceContext = graphics.GetHdc(); SetFontSmoothing(false); thirdPartyComponent.Render(deviceContext); SetFontSmoothing(true); This obviously has a horrible effect on the operating system, other applications flicker from cleartype enabled to disabled and back every time I render the image. So the question is, does anyone know how I can alter the font rendering settings for a specific DC? Even if I could just make the changes process or thread specific instead of affecting the whole operating system, that would be a big step forward! (That would give me the option of farming this rendering out to a separate process- the results are written to disk after rendering anyway) EDIT: I'd like to add that I don't mind if the solution is more complex than just a few API calls. I'd even be happy with a solution that involved hooking system dlls if it was only about a days work. EDIT: Background Information The third-party library renders using a palette of about 70 colors. After the image (which is actually a map tile) is rendered to the DC, I convert each pixel from it's 32-bit color back to it's palette index and store the result as an 8bpp greyscale image. This is uploaded to the video card as a texture. During rendering, I re-apply the palette (also stored as a texture) with a pixel shader executing on the video card. This allows me to switch and fade between different palettes instantaneously instead of needing to regenerate all the required tiles. It takes between 10-60 seconds to generate and upload all the tiles for a typical view of the world. EDIT: Renamed GraphicsDevice to Graphics The class GraphicsDevice in the previous version of this question is actually System.Drawing.Graphics. I had renamed it (using GraphicsDevice = ...) because the code in question is in the namespace MyCompany.Graphics and the compiler wasn't able resolve it properly. EDIT: Success! I even managed to port the PatchIat function below to C# with the help of Marshal.GetFunctionPointerForDelegate. The .NET interop team really did a fantastic job! I'm now using the following syntax, where Patch is an extension method on System.Diagnostics.ProcessModule: module.Patch( "Gdi32.dll", "CreateFontIndirectA", (CreateFontIndirectA original) => font => { font->lfQuality = NONANTIALIASED_QUALITY; return original(font); }); private unsafe delegate IntPtr CreateFontIndirectA(LOGFONTA* lplf); private const int NONANTIALIASED_QUALITY = 3; [StructLayout(LayoutKind.Sequential)] private struct LOGFONTA { public int lfHeight; public int lfWidth; public int lfEscapement; public int lfOrientation; public int lfWeight; public byte lfItalic; public byte lfUnderline; public byte lfStrikeOut; public byte lfCharSet; public byte lfOutPrecision; public byte lfClipPrecision; public byte lfQuality; public byte lfPitchAndFamily; public unsafe fixed sbyte lfFaceName [32]; }

    i have a class which in which iam using a method to get information from a session array via a for loop the 2 for loops in each method are used 1.to count total amount of items , and 2. to add up the total price but neither seem to be returning anything. im using the total amount to check it against the mc_gross posted value from an IPN and if the values are equal i plan to commit the sale to a database as it has been verified. for the method where im looking to get the total price im getting 0.00 returned to me. i think ive got the syntax wrong here somehow here is my class for purchase the two methods iam having trouble with are the gettotalcost() and gettotalitems() shown below is my class. <?php class purchase { private $itemnames; // from session array private $amountofitems; // from session array private $itemcost; //session array private $saleid; //posted transaction id value to be used in sale and sale item tables private $orderdate; //get current date time to be entered as datetime in sale table private $lastname; //posted from ipn private $firstname; //posted from ipn private $emailadd; //uses sessionarray value public function __construct($saleid,$firstname,$lastname) { $this->itemnames = $_SESSION['itemnames']; $this->amountofitems =$_SESSION['quantity']; $this->itemcost =$_SESSION['price']; $this->saleid = $saleid; $this->firstname = $firstname; $this->lastname = $lastname; $this->emailadd = $SESSION['username']; mail($myemail, "session vardump ", echo var_dump($_SESSION), "From: [email protected]" ); mail($myemail, "session vardump ",count($_SESSION['itemnames']) , "From: [email protected]" ); } public function commit() { $databaseinst = database::getinstance(); $databaseinst->connect(); $numrows = $databaseinst->querydb($query); //to be completed } public function gettotalitems() { $numitems; $i; for($i=0; $i < count($this->amountofitems);$i++) { $numitems += (int) $this->amountofitems[$i]; } return $numitems; } public function gettotalcost() { $totalcost; $i; for($i=0; $i < count($this->amountofitems);$i++) { $numitems = (int) $this->amountofitems[$i]; $costofitem =doubleval($this->itemcost [$i]); $totalcost += $numitems * $costofitem; } return $totalcost; } } ?> and here is where i create an instance of the class and attempt to use it. include("purchase.php"); $purchase = new purchase($_POST['txn_id'],$_POST['first_name'],$_POST['last_name']); $fullamount = $purchase->gettotalcost(); $fullAmount = number_format($fullAmount, 2); $grossAmount = $_POST['mc_gross']; if ($fullAmount != $grossAmount) { $message = "Possible Price Jack attempt! the amount the customer payed is : " . $grossAmount . " which is not equal to the full amount. the price of the products combined is " . $fullAmount. " the transaction number for which is " . $_POST['txn_id'] . "\n\n\n$req"; mail("XXXXXXXXXXXX", "Price Jack attempt ", $message, "From: [email protected]" ); exit(); // exit } thanks for the help in advance! ive also added these lines to my constructor. the mail returns that there is nothing in the vardump uh oh! mail($myemailaddress, "session vardump ", var_dump($_SESSION), "From: [email protected]" ); also added session_start(); at the top of the constructor and it dont work! help

  • XPath expression with condition on multiple ancestors

    - by Rest Wing
    The application I am developing receives an XML structure similar to following: <Root> <Valid> <Child name="Child1" /> <Container> <Child name="Child2" /> </Container> <Container> <Container> <Child name="Child3"/> <Child name="Child4"/> </Container> </Container> <Wrapper> <Child name="Child5" /> </Wrapper> <Wrapper> <Container> <Child name="Child19" /> </Container> </Wrapper> <Container> <Wrapper> <Child name="Child6" /> </Wrapper> </Container> <Container> <Wrapper> <Container> <Child name="Child20" /> </Container> </Wrapper> </Container> </Valid> <Invalid> <Child name="Child7" /> <Container> <Child name="Child8" /> </Container> <Container> <Container> <Child name="Child9"/> <Child name="Child10"/> </Container> </Container> <Wrapper> <Child name="Child11" /> </Wrapper> <Container> <Wrapper> <Child name="Child12" /> </Wrapper> </Container> </Invalid> </Root> I need to get a list of of Child elements under following conditions: Child is n generation descendant of Valid ancestor. Child may be m generation descendant of Container ancestor which is o generation descendant of Valid ancestor. Valid ancestors for Child element are Container elements as m generation ancestors and Valid element as first generation ancestor. where m, n, o are natural numbers. I need to write following XPath expressions Valid/Child Valid/Container/Child Valid/Container/Container/Child Valid/Container/Container/Container/Child ... as a single XPath expression. For provided example, the XPath expression would return only Child elements having name attribute equal to Child1, Child2, Child3 and Child4. The closest I have come to solution is following expression. Valid/Child | Valid//*[self::Container]/Child However, this would select Child element with name attribute equal to Child19 and Child20. Does XPath syntax supports either optional occurrence of an element or setting condition similar to self in previous example to all ancestors between Child and Valid elements?

  • Anyone willing to help out a javascript n00b? :-)

    - by Splynx
    Since I am asking for a lot, and know it, the following is a wall of text for those who might show some interest and want to know a little before offering their help to me. First a little about my level of programming skills, and a little about what I ask for. Where I'm at: I am not totally new to Javascript, and have dabbled a little with PHP earlier - well have dabbled a lot with PHP in fact, but never got good at it because I program alone. And I have until now never used forums to get help etc. other that searching to see if anyone else had my problem before and what the solution was. So I am not a intuitive or talented programmer, I'm more of a very maticulate programmer and you would be surprised how far you can get with if else... (ok that's a joke hehe). My solutions are usually (I am guessing here) not the best ones - and slow I take it, and the code is usually too long and I have to look up most of the stuff I use (really a lot of it is not done in "freehand"). I have a LOT of experience with HTML and CSS, and have always done well formed markup, as well as I am really into x-browsing and always require that my work validates when it's done. I also worry about optimizing a lot, and work with sprites for images, minimize the number of http requests etc, using H1,H2 etc. where it is logically correct, as well as use the correct elements and not just div span or p it... So because I am a workhorse and very maticulate I can actually pull off some quite "advanced" features, but it's always the basics that bite me in the end. Not fully understanding the syntax and so on usually gives me problems. Have recently discovered jQuery - wich is a lot of fun.... But I want to use it for the DOM node manipulation/handling only. As I mentioned I worry about optimizing, and jQuery used for everything seems... well not optimal, it strikes me as doing it yourself when possible is faster than accesing another script that may take a whole lot of other considerations into perspective when handling your variables and objects (and I am just guessing here since I as explained know nothing). So thats where I'm at... As mentioned I just started with javascript for "real" so I do not have much to show, but at the end of my WOT you can see two unfinisheded scripts I have made so you can see where I'm at roughly - just check out the URL without the /feedback.html for the second example (I am only allowed to post 1 link since I am also a SO n00b) (and for those rushing over to a validation service, remember I wrote "when it's done"...) What I ask for: I am figuring this... I have a piece of code I am working on at the moment, and this little project has taught me a whole lot already, and I have "grown" a lot as a javascript programmer. If I add a whole lot of comments to the script, and explain what it is intended to do, will you then show me where: I am writing incorrect code - making mistakes Where/how my code could be more optimal Where I am just simply being a muppet The code I want to use as the background for the tuition is the one here http://projects.1000monkeys.dk/feedback.html Use firebug and have a quick look see...

  • Why does this valid Tkinter code crash when mixed with a bit of PyWin32?

    - by Erlog
    So I'm making a very small program for personal use in tkinter, and I've run into a really strange wall. I'm mixing tkinter with the pywin32 bindings because I really hate everything to do with the syntax and naming conventions of pywin32, and it feels like tkinter gets more done with far less code. The strangeness is happening in the transition between the pywin32 clipboard watching and my program's reaction to it in tkinter. My window and all its controls are being handled in tkinter. The pywin32 bindings are doing clipboard watching and clipboard access when the clipboard changes. From what I've gathered about the way the clipboard watching pieces of pywin32 work, you can make it work with anything you want as long as you provide pywin32 with the hwnd value of your window. I'm doing that part, and it works when the program first starts. It just doesn't seem to work when the clipboard changes. When the program launches, it grabs the clipboard and puts it into the search box and edit box just fine. When the clipboard is modified, the event I want to fire off is firing off...except that event that totally worked before when the program launched is now causing a weird hang instead of doing what it's supposed to do. I can print the clipboard contents to stdout all I want if the clipboard changes, but not put that same data into a tkinter widget. It only hangs like that if it starts to interact with any of my tkinter widgets after being fired off by a clipboard change notification. It feels like there's some pywin32 etiquette I've missed in adapting the clipboard-watching sample code I was using over to my tkinter-using program. Tkinter apparently doesn't like to produce stack traces or error messages, and I can't really even begin to know what to look for trying to debug it with pdb. Here's the code: #coding: utf-8 #Clipboard watching cribbed from ## {{{ http://code.activestate.com/recipes/355593/ (r1) import pdb from Tkinter import * import win32clipboard import win32api import win32gui import win32con import win32clipboard def force_unicode(object, encoding="utf-8"): if isinstance(object, basestring) and not isinstance(object, unicode): object = unicode(object, encoding) return object class Application(Frame): def __init__(self, master=None): self.master = master Frame.__init__(self, master) self.pack() self.createWidgets() self.hwnd = self.winfo_id() self.nextWnd = None self.first = True self.oldWndProc = win32gui.SetWindowLong(self.hwnd, win32con.GWL_WNDPROC, self.MyWndProc) try: self.nextWnd = win32clipboard.SetClipboardViewer(self.hwnd) except win32api.error: if win32api.GetLastError () == 0: # information that there is no other window in chain pass else: raise self.update_search_box() self.word_search() def word_search(self): #pdb.set_trace() term = self.searchbox.get() self.resultsbox.insert(END, term) def update_search_box(self): clipboardtext = "" if win32clipboard.IsClipboardFormatAvailable(win32clipboard.CF_TEXT): win32clipboard.OpenClipboard() clipboardtext = win32clipboard.GetClipboardData() win32clipboard.CloseClipboard() if clipboardtext != "": self.searchbox.delete(0,END) clipboardtext = force_unicode(clipboardtext) self.searchbox.insert(0, clipboardtext) def createWidgets(self): self.button = Button(self) self.button["text"] = "Search" self.button["command"] = self.word_search self.searchbox = Entry(self) self.resultsbox = Text(self) #Pack everything down here for "easy" layout changes later self.searchbox.pack() self.button.pack() self.resultsbox.pack() def MyWndProc (self, hWnd, msg, wParam, lParam): if msg == win32con.WM_CHANGECBCHAIN: self.OnChangeCBChain(msg, wParam, lParam) elif msg == win32con.WM_DRAWCLIPBOARD: self.OnDrawClipboard(msg, wParam, lParam) # Restore the old WndProc.

  • Why does jquery leak memory so badly?

    - by Thomas Lane
    This is kind of a follow-up to a question I posted last week: http://stackoverflow.com/questions/2429056/simple-jquery-ajax-call-leaks-memory-in-ie I love the jquery syntax and all of its nice features, but I've been having trouble with a page that automatically updates table cells via ajax calls leaking memory. So I created two simple test pages for experimenting. Both pages do an ajax call every .1 seconds. After each successful ajax call, a counter is incremented and the DOM is updated. The script stops after 1000 cycles. One uses jquery for both the ajax call and to update the DOM. The other uses the Yahoo API for the ajax and does a document.getElementById(...).innerHTML to update the DOM. The jquery version leaks memory badly. Running in drip (on XP Home with IE7), it starts at 9MB and finishes at about 48MB, with memory growing linearly the whole time. If I comment out the line that updates the DOM, it still finishes at 32MB, suggesting that even simple DOM updates leak a significant amount of memory. The non-jquery version starts and finishes at about 9MB, regardless of whether it updates the DOM. Does anyone have a good explanation of what is causing jquery to leak so badly? Am I missing something obvious? Is there a circular reference that I'm not aware of? Or does jquery just have some serious memory issues? Here is the source for the leaky (jquery) version: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); </script> <script type="text/javascript"> var counter = 0; leakTest(); function leakTest() { $.ajax({ url: '/html/delme.x', type: 'GET', success: incrementCounter }); } function incrementCounter(data) { if (counter<1000) { counter++; $('#counter').text(counter); setTimeout(leakTest,100); } else $('#counter').text('finished.'); } </script> </head> <body> <div>Why is memory usage going up?</div> <div id="counter"></div> </body> </html> And here is the non-leaky version: <html> <head> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/yahoo/yahoo-min.js"></script> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/event/event-min.js"></script> <script type="text/javascript" src="http://yui.yahooapis.com/2.8.0r4/build/connection/connection_core-min.js"></script> <script type="text/javascript"> var counter = 0; leakTest(); function leakTest() { YAHOO.util.Connect.asyncRequest('GET', '/html/delme.x', {success:incrementCounter}); } function incrementCounter(o) { if (counter<1000) { counter++; document.getElementById('counter').innerHTML = counter; setTimeout(leakTest,100); } else document.getElementById('counter').innerHTML = 'finished.' } </script> </head> <body> <div>Memory usage is stable, right?</div> <div id="counter"></div> </body> </html>
