  • Adding a imageview to child elements in a expandable list query

    - by Thomas Millin
    I am looking to find out how to assign an image to a imageview in each child of an expandable list. If anyone has any information or links to find out how to do this I would be most appreciative. expListAdapter = new SimpleExpandableListAdapter( main.this, createGroupList(), R.layout.parentnode, new String[] { "day", "number" }, new int[] { R.id.TextView01, R.id.TextView02 }, createChildList(), R.layout.child_row, new String[] { "image", "childName", "date"}, new int[] { R.id.ImageView01, R.id.childname, R.id.date } ); setListAdapter( expListAdapter ); is what my adapter looks like at the moment, I have very little experience in customising adapters so I do not know where to start. Any help would be great :D

  • How do you overide a class that is called by another class with parent::method

    - by dan.codes
    I am trying to extend Mage_Catalog_Block_Product_View I have it setup in my local directory as its own module and everything works fine, I wasn't getting the results that I wanted. I then saw that another class extended that class as well. The method I am trying to override is the protected function _prepareLayout() This is the function class Mage_Review_Block_Product_View extends Mage_Catalog_Block_Product_View protected function _prepareLayout() { $this-&gt;getLayout()-&gt;createBlock('catalog/breadcrumbs'); $headBlock = $this-&gt;getLayout()-&gt;getBlock('head'); if ($headBlock) { $title = $this-&gt;getProduct()-&gt;getMetaTitle(); if ($title) { $headBlock-&gt;setTitle($title); } $keyword = $this-&gt;getProduct()-&gt;getMetaKeyword(); $currentCategory = Mage::registry('current_category'); if ($keyword) { $headBlock-&gt;setKeywords($keyword); } elseif($currentCategory) { $headBlock-&gt;setKeywords($this-&gt;getProduct()-&gt;getName()); } $description = $this-&gt;getProduct()-&gt;getMetaDescription(); if ($description) { $headBlock-&gt;setDescription( ($description) ); } else { $headBlock-&gt;setDescription( $this-&gt;getProduct()-&gt;getDescription() ); } } return parent::_prepareLayout(); } I am trying to modify it just a bit with the following, keep in mind I know there is a title prefix and suffix but I needed it only for the product page and also I needed to add text to the description. class MyCompany_Catalog_Block_Product_View extends Mage_Catalog_Block_Product_View protected function _prepareLayout() { $storeId = Mage::app()-&gt;getStore()-&gt;getId(); $this-&gt;getLayout()-&gt;createBlock('catalog/breadcrumbs'); $headBlock = $this-&gt;getLayout()-&gt;getBlock('head'); if ($headBlock) { $title = $this-&gt;getProduct()-&gt;getMetaTitle(); if ($title) { if($storeId == 2){ $title = "Pool Supplies Fast - " .$title; $headBlock-&gt;setTitle($title); } $headBlock-&gt;setTitle($title); }else{ $path = Mage::helper('catalog')-&gt;getBreadcrumbPath(); foreach ($path as $name =&gt; $breadcrumb) { $title[] = $breadcrumb['label']; } $newTitle = "Pool Supplies Fast - " . join($this-&gt;getTitleSeparator(), array_reverse($title)); $headBlock-&gt;setTitle($newTitle); } $keyword = $this-&gt;getProduct()-&gt;getMetaKeyword(); $currentCategory = Mage::registry('current_category'); if ($keyword) { $headBlock-&gt;setKeywords($keyword); } elseif($currentCategory) { $headBlock-&gt;setKeywords($this-&gt;getProduct()-&gt;getName()); } $description = $this-&gt;getProduct()-&gt;getMetaDescription(); if ($description) { if($storeId == 2){ $description = "Pool Supplies Fast - ". $this-&gt;getProduct()-&gt;getName() . " - " . $description; $headBlock-&gt;setDescription( ($description) ); }else{ $headBlock-&gt;setDescription( ($description) ); } } else { if($storeId == 2){ $description = "Pool Supplies Fast: ". $this-&gt;getProduct()-&gt;getName() . " - " . $this-&gt;getProduct()-&gt;getDescription(); $headBlock-&gt;setDescription( ($description) ); }else{ $headBlock-&gt;setDescription( $this-&gt;getProduct()-&gt;getDescription() ); } } } return Mage_Catalog_Block_Product_Abstract::_prepareLayout(); } This executs fine but then I notice that the following class Mage_Review_Block_Product_View_List extends which extends Mage_Review_Block_Product_View and that extends Mage_Catalog_Block_Product_View as well. Inside this class they call the _prepareLayout as well and call the parent with parent::_prepareLayout() class Mage_Review_Block_Product_View_List extends Mage_Review_Block_Product_View protected function _prepareLayout() { parent::_prepareLayout(); if ($toolbar = $this-&gt;getLayout()-&gt;getBlock('product_review_list.toolbar')) { $toolbar-&gt;setCollection($this-&gt;getReviewsCollection()); $this-&gt;setChild('toolbar', $toolbar); } return $this; } So obviously this just calls the same class I am extending and runs the function I am overiding but it doesn't get to my class because it is not in my class hierarchy and since it gets called after my class all the stuff in the parent class override what I have set. I'm not sure about the best way to extend this type of class and method, there has to be a good way to do this, I keep finding I am running into issues when trying to overide these prepare methods that are derived from the abstract classes, there seems to be so many classes overriding them and calling parent::method. What is the best way to override these functions?

  • Inserting variables into a query string - it won't work!

    - by Jonesy
    Basically i have a query string that when i hardcode in the catalogue value its fine. when I try adding it via a variable it just doesn't pick it up. This works: Dim WaspConnection As New SqlConnection("Data Source=JURA;Initial Catalog=WaspTrackAsset_NROI;User id=" & ConfigurationManager.AppSettings("WASPDBUserName") & ";Password='" & ConfigurationManager.AppSettings("WASPDBPassword").ToString & "';") This doesn't: Public Sub GetWASPAcr() connection.Open() Dim dt As New DataTable() Dim username As String = HttpContext.Current.User.Identity.Name Dim sqlCmd As New SqlCommand("SELECT WASPDatabase FROM dbo.aspnet_Users WHERE UserName = '" & username & "'", connection) Dim sqlDa As New SqlDataAdapter(sqlCmd) sqlDa.Fill(dt) If dt.Rows.Count > 0 Then For i As Integer = 0 To dt.Rows.Count - 1 If dt.Rows(i)("WASPDatabase") Is DBNull.Value Then WASP = "" Else WASP = "WaspTrackAsset_" + dt.Rows(i)("WASPDatabase") End If Next End If connection.Close() End Sub Dim WaspConnection As New SqlConnection("Data Source=JURA;Initial Catalog=" & WASP & ";User id=" & ConfigurationManager.AppSettings("WASPDBUserName") & ";Password='" & ConfigurationManager.AppSettings("WASPDBPassword").ToString & "';") When I debug the catalog is empty in the query string but the WASP variable holds the value "WaspTrackAsset_NROI" Any idea's why? Cheers, jonesy

    I have a test class that I'm trying to run from a main method with the folowing code : Result r = org.junit.runner.JUnitCore.runClasses(TestReader.class); when I examine the Result object I can see that 5 tests have been run but nothing is printed on the screen. Should I do something else to get an output ?

  • Platform configuration for projects in VS 2010

    - by Thomas Wanner
    I have a third-party project type in Visual Studio which for some reason only supports the .NET Platform configuration for the build, for all other (standard C#) projects in the solution I only have AnyCPU. Unfortunately, ever since upgrading to VS 2010 it produces following error when built : Error 39 The OutputPath property is not set for project 'ReferencedBusinessProject.csproj'. Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Configuration='Debug' Platform='.NET'. This error may also appear if some other project is trying to follow a project-to-project reference to this project, this project has been unloaded or is not included in the solution, and the referencing project does not build using the same or an equivalent Configuration or Platform. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets 483 10 CustomTypeProject It's pretty much descriptive in what is missing but I haven't found any way to fix it so far. Do you have any idea how this can be resolved or what can be the problem ?

  • "svn: Delta source ended unexpectedly" and proxy server

    - by Vladimir Bezugliy
    I cannot checkout working copy if I use proxy server. SVN starting to checkout files but, checkout several files but then stops and shows following error: svn: Delta source ended unexpectedly I can checkout working copy if I work without proxy server. But I constantly have problems if I work via proxy. Is this problem with proxy server or with svn? UPDATED: I tried to access other svn repositories located on different servers via proxy and it seems to me that I have problem only with one svn server. Other svn servers are accessible via proxy server.

  • Parallel Computing in .Net 4.0

    - by kaleidoscope
    Technorati Tags: Ram,Parallel Computing in .Net 4.0 Parallel computing is the simultaneous use of multiple compute resources to solve a computational problem: To be run using multiple CPUs A problem is broken into discrete parts that can be solved concurrently Each part is further broken down to a series of instructions Instructions from each part execute simultaneously on different CPUs Parallel Extensions in .NET 4.0 provides a set of libraries and tools to achieve the above mentioned objectives. This supports two paradigms of parallel computing Data Parallelism – This refers to dividing the data across multiple processors for parallel execution.e.g we are processing an array of 1000 elements we can distribute the data between two processors say 500 each. This is supported by the Parallel LINQ (PLINQ) in .NET 4.0 Task Parallelism – This breaks down the program into multiple tasks which can be parallelized and are executed on different processors. This is supported by Task Parallel Library (TPL) in .NET 4.0 A high level view is shown below:

  • Getting TF215097 error after modifying a build process template in TFS Team Build 2010

    - by Jakob Ehn
    When embracing Team Build 2010, you typically want to define several different build process templates for different scenarios. Common examples here are CI builds, QA builds and release builds. For example, in a contiuous build you often have no interest in publishing to the symbol store, you might or might not want to associate changesets and work items etc. The build server is often heavily occupied as it is, so you don’t want to have it doing more that necessary. Try to define a set of build process templates that are used across your company. In previous versions of TFS Team Build, there was no easy way to do this. But in TFS 2010 it is very easy so there is no excuse to not do it! :-)   I ran into a scenario today where I had an existing build definition that was based on our release build process template. In this template, we have defined several different build process parameters that control the release build. These are placed into its own sectionin the Build Process Parameters editor. This is done using the ProcessParameterMetadataCollection element, I will explain how this works in a future post.   I won’t go into details on these parametes, the issue for this blog post is what happens when you modify a build process template so that it is no longer compatible with the build definition, i.e. a breaking change. In this case, I removed a parameter that was no longer necessary. After merging the new build process template to one of the projects and queued a new release build, I got this error:   TF215097: An error occurred while initializing a build for build definition <Build Definition Name>: The values provided for the root activity's arguments did not satisfy the root activity's requirements: 'DynamicActivity': The following keys from the input dictionary do not map to arguments and must be removed: <Parameter Name>.  Please note that argument names are case sensitive. Parameter name: rootArgumentValues <Parameter Name> was the parameter that I removed so it was pretty easy to understand why the error had occurred. However, it is not entirely obvious how to fix the problem. When open the build definition everything looks OK, the removed build process parameter is not there, and I can open the build process template without any validation warnings. The problem here is that all settings specific to a particular build definition is stored in the TFS database. In TFS 2005, everything that was related to a build was stored in TFS source control in files (TFSBuild.proj, WorkspaceMapping.xml..). In TFS 2008, many of these settings were moved into the database. Still, lots of things were stored in TFSBuild.proj, such as the solution and configuration to build, wether to execute tests or not. In TFS 2010, all settings for a build definition is stored in the database. If we look inside the database we can see what this looks like. The table tbl_BuildDefinition contains all information for a build definition. One of the columns is called ProcessParameters and contains a serialized representation of a Dictionary that is the underlying object where these settings are stoded. Here is an example:   <Dictionary x:TypeArguments="x:String, x:Object" xmlns="clr-namespace:System.Collections.Generic;assembly=mscorlib" xmlns:mtbwa="clr-namespace:Microsoft.TeamFoundation.Build.Workflow.Activities;assembly=Microsoft.TeamFoundation.Build.Workflow" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <mtbwa:BuildSettings x:Key="BuildSettings" ProjectsToBuild="$/PathToProject.sln"> <mtbwa:BuildSettings.PlatformConfigurations> <mtbwa:PlatformConfigurationList Capacity="4"> <mtbwa:PlatformConfiguration Configuration="Release" Platform="Any CPU" /> </mtbwa:PlatformConfigurationList> </mtbwa:BuildSettings.PlatformConfigurations> </mtbwa:BuildSettings> <mtbwa:AgentSettings x:Key="AgentSettings" Tags="Agent1" /> <x:Boolean x:Key="DisableTests">True</x:Boolean> <x:String x:Key="ReleaseRepositorySolution">ERP</x:String> <x:Int32 x:Key="Major">2</x:Int32> <x:Int32 x:Key="Minor">3</x:Int32> </Dictionary> Here we can see that it is really only the non-default values that are persisted into the databasen. So, the problem in my case was that I removed one of the parameteres from the build process template, but the parameter and its value still existed in the build definition database. The solution to the problem is to refresh the build definition and save it. In the process tab, there is a Refresh button that will reload the build definition and the process template and synchronize them:   After refreshing the build definition and saving it, the build was running successfully again.

  • Installing mysql-server with python ssh connection

    - by mrbox
    I'm writing a script in Python, which is connecting to server via ssh, then installing some packages. But there is problem with dialogue box, where i can type in a root password- i don't know how to send data there. Once I tried to do this, my apt(using Debian Lenny) gone crazy. Here is some info: - Debian Lenny - Using PySSH with easier interface, code looks like this: clientSSH = SSHClient( self.ip, 'root', self.rootPassword, None ) clientSSH.login() clientSSH.run_command('apt-get install mysql-server mysql-client php5') clientSSH.run_command('Y') #I Don't know how send root passwd here clientSSH.logout()

  • Client/server application RPC connection gets disconnected very frequently

    - by Chris Thompson
    I have a client/server application that uses RPC for the client to communicate with the server. Fairly regularly, I get an event in the Application log that the RPC connection was disconnected: Client callback failed ((0x80010108) ) I have the Windows Firewall disabled on both machines. I've even run the client on a second computer with a clean Windows XP install without any group policies. This has been going on for a long time and no one has been able to figure out why it's happening. The same client/server app works fine at other client locations. Any thoughts?

  • What can cause peaks in pagetables in /proc/meminfo ?

    - by Fuzzy76
    I have a gameserver running Debian Lenny on a VPS host. Even when experiencing a fairly low load, the players start experiencing major lag (ping times rise from 50 ms to 150-500 ms) in bursts of 3 - 10 seconds. I have installed Munin server monitoring, but when looking at the graphs it looks like the server has plenty of CPU, RAM and bandwidth available. The only weird thing I noticed is some peaks in the memory graph attributed to "page_tables" which maps to PageTables in /proc/meminfo but I can't find any good information on what this might mean. Any ideas what might be causing this? If you need any more graps, just let me know. The interrupts/second count is at roughly 400-600 during this period (nearly all from eth0). The drop in committed was caused by me trying to lower the allocated memory for the server from 512MB to 256MB, but that didn't seem to help.

  • Jquery dynamic dropdown event not firing

    - by kevin
    Hi i am trying to create dropdownlists dynamically and populating the contents via an ajax call, this sort of works in the sense that the drop down is created and populated as required but its 'change' event does not fire. I am posting the code below, if anyone can spot something obvious, can you please let me know regards $(document).ready(function () { $("#positions select").change(function (e) { alert("in"); var id = $("#category_id").val(); $.getJSON("/Category/GetSubCategories/" + id, function (data) { if (data.length > 0) { alert(data.length); var position = document.getElementById('positions'); var tr = position.insertRow(7); var td1 = tr.insertCell(-1); var td = tr.insertCell(-1); var sel = document.createElement("select"); sel.name = 'sel'; sel.id = 'sel'; sel.setAttribute('class', 'category'); td.appendChild(sel); $.each(data, function (GetSubCatergories, category) { $('#sel').append($("<option></option>"). attr("value", category.category_id). text(category.name)); }); } }); }); });

  • What is the best approach towards styling GWT applications?

    - by Ashwin
    General approach in GWT is to use Panels and then apply custom CSS themes to get a customized look. While I can achieve a certain extent of personalization of my GWT app through CSS tinkering, I was wondering how others generally approach styling. Some of the suggestions I came across the web were to manage layout with plain HTML, through use of HTMLPanel's. This way one can straightaway use the HTML mock-up within the application without having to code all the layout. So what in your opinion is the best and least painful way to approach layout and custom styling of GWT application?

  • XML structure question

    - by Andrew Jahn
    I have a basic XML object that I'm working with. I can't figure out how to access the parts of it. EX:<br> <pre><code> < FacetsData> < Collection name="CDDLALL" type="Group"> < SubCollection name="CDDLALL" type="Row"> < Column name="DPDP_ID">D0230< /Column> < Column name="Count">9< /Column> < /SubCollection> < SubCollection name="CDDLALL" type="Row"> < Column name="DPDP_ID">D1110< /Column> < Column name="Count">9< /Column> < /SubCollection> < /Collection> < /FacetsData> (PS: I can't get this damn xml to format so people can read it) What I need to do is check each DPDP_ID and if its value is D0230 then I leave the Count alone, all else I change the Count to 1. What I have so far: node = doc.DocumentElement; nodeList = node.SelectNodes("/FacetsData/Collection/SubCollection"); for (int x = 0; x < nodeList.Count; x++) { if (nodeList[x].HasChildNodes) { for (int i = 0; i < nodeList[x].ChildNodes.Count; i++) { //This part I can't figure out how to get the name="" part of the xml //MessageBox.Show(oNodeList[x].ChildNodes[i].InnerText); get the "D0230","1" //part but not the "DPDP_ID","Count" part. } } }

    Lotus Notes 8.5 - yuck! User is trying to move an email from the Inbox into a subfolder and is using the menu option (not dragging & dropping) the email simply fails to move. It just appears again in the inbox. Drag and drop has the same effect! I have checked that it is a failure to move and not just a copy/delete issue. I am not a Notes adminstrator, being more of a MS Exchange administrator by career path and have no idea what to be looking for.

  • Declaring a string array in class header file - compiler thinks string is variable name?

    - by Dave
    Hey everybody, I need a bit of a hand with declaring a string array in my class header file in C++. atm it looks like this: //Maze.h #include <string> class Maze { GLfloat mazeSize, mazeX, mazeY, mazeZ; string* mazeLayout; public: Maze ( ); void render(); }; and the constructor looks like this: //Maze.cpp #include <GL/gl.h> #include "Maze.h" #include <iostream> #include <fstream> Maze::Maze( ) { cin >> mazeSize; mazeLayout = new string[mazeSize]; mazeX = 2/mazeSize; mazeY = 0.25; mazeZ = 2/mazeSize; } I'm getting a compiler error that says: In file included from model-view.cpp:11: Maze.h:14: error: ISO C++ forbids declaration of ‘string’ with no type Maze.h:14: error: expected ‘;’ before ‘*’ token and the only sense that makes to me is that for some reason it thinks I want string as a variable name not as a type declaration. If anybody could help me out that would be fantastic, been looking this up for a while and its giving me the shits lol. Cheers guys

  • Custom validatior in ASP.net

    - by DJPB
    Hi there. I'm working on an ASP.NET/C# app. I have 2 text boxes and I need to validate if the input text for both of them are not both null ex: if(string.IsNullOrEmpty(TextBox1.Text) && string.IsNullOrEmpty(TextBox2.Text) ) //FAIL!!! else // OK! that is, at least one txtBox has values I was planning on using a custom validator but it seems that the validation function only gets called when something is written on the textBox i'm using has the 'control to validate'. Now, that doesn't work for me since I want to show an error message when both text boxes are empty. Is there a way to make the validation function to be called with, for example a postback? Or is there any other better approach to this case than the custom validator? tks
