  • Keeping track of leading zeros with BitSet in Java

    - by Ryan
    So, according to this question there are two ways to look at the size of a BitSet. size(), which is legacy and not really useful. I agree with this. The size is 64 after doing: BitSet b = new BitSet(8); length(), which returns the index of the highest set bit. In the above example, length() will return 0. This is somewhat useful, but doesn't accurately reflect the number of bits the BitSet is supposed to be representing in the event you have leading zeros. The information I'm dealing with rarely(if ever) falls evenly into 8-bit bytes, and the leading 0s are just as important to me as the 1s. I have some data fields that are 333 bits long, some that are 20, etc. Is there a better way to deal with bit-level details in Java that will keep track of leading zeros? Otherwise, I'm going to have to 'roll my own', so to speak. To which I have a few ideas already, but I'd prefer not to reinvent the wheel if possible.

  • MSBuild - setting a reference path

    - by Ryan
    I have several assemblies my project is dependant upon. These are stored in the Project's directory under the "Dependencies" folder. So something like this. Solution - Project - Dependancies FunkyAssembly.dll - bin - Debug - Release SomeCode.cs I've referenced FunkyAssembly.dll using Browse and in project.csproj I see <Reference Include="FunkyAssembly"> <HintPath>Dependancies\FunkyAssembly.dll</HintPath> </Reference> So far so good - except after a release build FunkyAssembly.dll is copied to the Release directory (not a problem in itself) but then future debug builds will reference this copy rather than the copy in Dependencies. You can see this if you at Path in the reference properties. This means that if Dependencies\FunkyAssembly.dll is updated the build won't pick it up as its referencing the old copy in bin/Release. Any way to FORCE the damn thing to pick up Dependencies\FunkyAssembly.dll rather than HINT?

  • Jquery getJSON populate select menu question...

    - by Scott
    I am populating a select menu with getJSON. I am wondering if there's a way that I can use jQuery's .each function to bring in these values? Surely there must be an easier way to accomplish this...maybe? PHP file: <?php $queryMonth = "SELECT monthID, month FROM months"; $result = $db->query($queryMonth); while($rowMonth = $db->fetch_assoc($result)) : $data[] = $rowMonth; endwhile; echo json_encode($data); ?> The jQuery: $.getJSON('selectMenus.php', function(data){ $("select.month").append("<option value=" + data[0].monthID + ">" + data[0].month + "</option>"); $("select.month").append("<option value=" + data[1].monthID + ">" + data[1].month + "</option>"); $("select.month").append("<option value=" + data[2].monthID + ">" + data[2].month + "</option>"); $("select.month").append("<option value=" + data[3].monthID + ">" + data[3].month + "</option>"); $("select.month").append("<option value=" + data[4].monthID + ">" + data[4].month + "</option>"); $("select.month").append("<option value=" + data[5].monthID + ">" + data[5].month + "</option>"); $("select.month").append("<option value=" + data[6].monthID + ">" + data[6].month + "</option>"); $("select.month").append("<option value=" + data[7].monthID + ">" + data[7].month + "</option>"); $("select.month").append("<option value=" + data[8].monthID + ">" + data[8].month + "</option>"); $("select.month").append("<option value=" + data[9].monthID + ">" + data[9].month + "</option>"); $("select.month").append("<option value=" + data[10].monthID + ">" + data[10].month + "</option>"); $("select.month").append("<option value=" + data[11].monthID + ">" + data[11].month + "</option>"); }); my json output looks like this: [{"monthID":"1","month":"January"},{"monthID":"2","month":"February"},{"monthID":"3","month":"March"},{"monthID":"4","month":"April"},{"monthID":"5","month":"May"},{"monthID":"6","month":"June"},{"monthID":"7","month":"July"},{"monthID":"8","month":"August"},{"monthID":"9","month":"Septemeber"},{"monthID":"10","month":"October"},{"monthID":"11","month":"November"},{"monthID":"12","month":"December"}]

  • Regular expression in BASH

    - by Ryan
    Hello everyone, I was hoping someone could answer my quick question as I am going nuts! I have recently started learning regular expressions in my Java programming however am a little confused how to get certain features to work correctly directly in BASH. For example, the following code is not working as I think it should. echo 2222 | grep '2\{2\}' I am expecting it to return: 22 I have tried variations of it including: echo 2222 | grep '2{2}' echo 2222 | grep -P '2\{2\}' echo 2222 | grep -E '2\{2\}' However I am completely out of ideas. I'm sure this is a simple parameter / syntax fix and would love some help! P.S I've done tons of googling and every reference I find does not work in BASH; regex's can run on so many different platforms and engines =/

  • Are there any command line tools for controllable XML formatting?

    - by Scott Stafford
    Hi - I am searching for a command-line tool (or XSLT technique, or C# code that can be made into a command-line tool, etc) for Windows that will do XML pretty-printing. Specifically, I want one that has the ability to put attributes one-to-a-line, something like: <Node> <ChildNode value1='5' value2='6' value3='happy' /> </Node> It doesn't have to be EXACTLY like that, but I want to use it for an XML file that has nodes with dozens of attributes and spreading them across multiple lines makes them easier to read, edit, and text-diff.

  • Coding solution to WAR installation error (Websphere Portal 6.0) ?

    - by Scott Leis
    I have a Websphere Portal application containing several portlets for which I'm currently working on some changes. A week ago, the WAR file produced by Rational Application Developer could be installed on the Portal server with no problems. Yesterday I made some seemingly minor changes to two JSP files and their associated "pagecode" Java files, and attempting to update the WAR on the server (using the Portal Administration web interface) now produces an error message. The WAR upload works, and the system shows me the correct list of portlets in the WAR file, but clicking "Finish" gives me a page with the error message "EJPAQ1319E: Cannot install the selected WAR file. View Details". Clicking the "View Details" link gives me a page with the following text: EJPAQ1319E: Cannot install the selected WAR file. com.ibm.portal.WpsException: EJPAQ1319E: Cannot install the selected WAR file. at com.ibm.wps.portlets.portletmanager.actions.DoInstallWebModuleAction.installPortletFromFormFile(DoInstallWebModuleAction.java:633) at com.ibm.wps.portlets.portletmanager.actions.DoInstallWebModuleAction.doExecute(DoInstallWebModuleAction.java:159) at com.ibm.wps.portlets.adminstruts.actions.BaseAction.execute(BaseAction.java:64) at com.ibm.wps.portlets.struts.WpsRequestProcessor.processActionPerform(WpsRequestProcessor.java:338) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:274) at com.ibm.wps.portlets.struts.WpsStrutsPortlet.processActionPerformed(WpsStrutsPortlet.java:1947) at com.ibm.wps.portlets.struts.WpsStrutsPortlet.actionPerformed(WpsStrutsPortlet.java:1637) at com.ibm.wps.portlets.adminstruts.WpsAdminStrutsPortlet.actionPerformed(WpsAdminStrutsPortlet.java:261) at com.ibm.wps.pe.pc.legacy.SPIPortletInterceptorImpl.handleEvents(SPIPortletInterceptorImpl.java:323) EJPPE0020E: It is not allowed to install a JSR 168 compliant over a 4.x portlet application. com.ibm.wps.command.applications.AppWarFileException: EJPPE0020E: It is not allowed to install a JSR 168 compliant over a 4.x portlet application.

Explanation: A portlet application containing legacy portlets can only be updated with another portlet application that contains legacy portlets. The same is true for standard portlet applications. User Response: Modify the portlet.xml of the application such that it matches the original API type, standard or legacy and try again. However, the "portlet.xml" file has not changed in about a month, and I've done several WAR updates for this application in that time with no problems. The problem seems to be caused by the code changes I did yesterday, but I have no clue why a few lines of code would do this. Any ideas?

  • Binding Source suspends itself when I don't want it to.

    - by Scott Chamberlain
    I have two data tables set up in a Master-Details configuration with a relation "Ticket_CallSegments" between them. I also have two Binding Sources and a Data Grid View configured like this (Init Code) // // dgvTickets // this.dgvTickets.AllowUserToAddRows = false; this.dgvTickets.AllowUserToDeleteRows = false; this.dgvTickets.AllowUserToResizeRows = false; this.dgvTickets.AutoGenerateColumns = false; this.dgvTickets.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize; this.dgvTickets.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] { this.cREATEDATEDataGridViewTextBoxColumn, this.contactFullNameDataGridViewTextBoxColumn, this.pARTIALNOTEDataGridViewTextBoxColumn}); this.dgvTickets.DataSource = this.ticketsDataSetBindingSource; this.dgvTickets.Dock = System.Windows.Forms.DockStyle.Fill; this.dgvTickets.Location = new System.Drawing.Point(0, 0); this.dgvTickets.MultiSelect = false; this.dgvTickets.Name = "dgvTickets"; this.dgvTickets.ReadOnly = true; this.dgvTickets.RowHeadersVisible = false; this.dgvTickets.SelectionMode = System.Windows.Forms.DataGridViewSelectionMode.FullRowSelect; this.dgvTickets.Size = new System.Drawing.Size(359, 600); this.dgvTickets.TabIndex = 0; // // ticketsDataSetBindingSource // this.ticketsDataSetBindingSource.DataMember = "Ticket"; this.ticketsDataSetBindingSource.DataSource = this.ticketsDataSet; this.ticketsDataSetBindingSource.CurrentChanged += new System.EventHandler(this.ticketsDataSetBindingSource_CurrentChanged); // // callSegementBindingSource // this.callSegementBindingSource.DataMember = "Ticket_CallSegments"; this.callSegementBindingSource.DataSource = this.ticketsDataSetBindingSource; this.callSegementBindingSource.Sort = "CreateDate"; //Function to update a rich text box. private void ticketsDataSetBindingSource_CurrentChanged(object sender, EventArgs e) { StringBuilder sb = new StringBuilder(); rtbTickets.Clear(); foreach (DataRowView drv in callSegementBindingSource) { TicketsDataSet.CallSegmentsRow row = (TicketsDataSet.CallSegmentsRow)drv.Row; sb.AppendLine("**********************************"); sb.AppendLine(String.Format("CreateDate: {1}, Created by: {0}", row.USERNAME, row.CREATEDATE)); sb.AppendLine("**********************************"); rtbTickets.SelectionFont = new Font("Arial", (float)11, FontStyle.Bold); rtbTickets.SelectedText = sb.ToString(); rtbTickets.SelectionFont = new Font("Arial", (float)11, FontStyle.Regular); rtbTickets.SelectedText = row.NOTES + "\n\n"; } } However when ticketsDataSetBindingSource_CurrentChanged gets called when I select a new row in my Data Grid View callSegementBindingSource.IsBindingSuspended is set to true and my text box does not update correctly (it seems to always pull from the same row in CallSegments). Can anyone see what I am doing wrong or tell me how to unsuspend the binding so it will pull the correct data?

  • Ignore certificate errors when requesting a URL in Java

    - by Ryan Elkins
    I'm trying to print a URL (without having a browser involved at all) but the URL is currently throwing the following: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I'm calling the URL using a JEditorPane's setPage method, which just takes a URL as a parameter. Assuming I can't change anything server side and I still need to get to this resource, how would I go about ignoring the certificate error (or something else that gets me to my goal)? Accessing this URL via a browser tells me the site is untrusted and asks me if I want to proceed.

  • Using Multiple File Handles for Single File

    - by Ryan Rosario
    I have an O(n^2) operation that requires me to read line i from a file, and then compare line i to every line in the file. This repeats for all i. I wrote the following code to do this with 2 file handles, but it does not yield the result I am looking for. I imagine this is a simple error on my part. IN1 = open("myfile.dat","r") IN2 = open("myfile.dat","r") for line1 in IN1: for line2 in IN2: print line1.strip(), line2.strip() IN1.close() IN2.close() The result: Hello Hello Hello World Hello This Hello is Hello an Hello Example Hello of Hello Using Hello Two Hello File Hello Pointers Hello to Hello Read Hello One Hello File The output should contain 15^2 lines.

  • How can I tell if a set of parens in perl code will act as grouping parens or form a list?

    - by Ryan Thompson
    In perl, parentheses are used for overriding precedence (as in most programming languages) as well as for creating lists. How can I tell if a particular pair of parens will be treated as a grouping construct or a one-element list? For example, I'm pretty sure this is a scalar and not a one-element list: (1 + 1) But what about more complex expressions? Is there an easy way to tell?

  • javax.sql.DataSource.getConnection() locks system

    - by Ryan Elkins
    I'm using the Apache Commons DBCP library for connection pooling in a desktop application. I've done this before and never had a problem but the latest application has started sometimes locking up on the call to getConnection() on my DataSource. The application just hangs after that call. I'm closing up my resources when I'm done with them. Is there any known reason why this might happen? I'm not even sure where to being troubleshooting this now that I've got it narrowed down to this method. It doesn't always hang - sometimes it happens fairly quickly, sometimes it takes a long time. Sometimes it doesn't happen at all, although lately I can get it to happen within a few minutes.

  • ng-grid get filtered column count after filtering

    - by Ryan Langton
    I'm using ng-grid with filtering. Any time the filter updates I want to get the filtered item count. I have been able to do this using the filteredRows property of ngGrid. However I'm getting the rows BEFORE the filtering occurs and I want them AFTER the filtering occurs. Here is a plunker to demonstrate the behavior: http://plnkr.co/edit/onyE9e?p=preview Here is the code where filtering is occuring: $scope.$watch('gridOptions.filterOptions.filterText2', function(searchText, oldsearchText) { if (searchText !== oldsearchText) { $scope.gridOptions.filterOptions.filterText = "name:" + searchText + "; "; $scope.recordCount = $scope.gridOptions.ngGrid.filteredRows.length; } });

  • Is anyone else experiencing weird debug + crash behavior with Silverlight?

    - by Scott Barnes
    I have noticed that after awhile of debug/tweakcode/debug etc that eventually Silverlight starts to crash all of my browsers (i.e. doesn't matter which i fire, they all just crash). If i then go to a site that has Silverlight, it works fine? so it has something to do with debugger + Silverlight not getting along? I then reboot and the problem goes away? Is anyone else experiencing this kind of weird behaviour? I have noticed though that if i put breakpoints on the code they all seem to halt, in that it appears that it can instantiate the said .xap etc ok, but just can't seem to render it to screen without a crash? (There's nothing in the log files and i've tried to attach a seperate VS2008 instance to both IE, Devenv and Blend etc trying to see if i can catch what's causing this to occur?)

  • Issues with mx:method, mx.rpc.remoting.mxml.RemoteObject, and sub-classing mx.rpc.remoting.mxml.Remo

    - by Ryan Wilson
    I am looking to subclass RemoteObject. Instead of: <mx:RemoteObject ... > <mx:method ... /> <mx:method ... /> </mx:RemoteObject> I want to do something like: <remoting:CustomRemoteObject ...> <mx:method ... /> <mx:method ... /> </remoting:CustomRemoteObject> where CustomRemoteObject extends mx.rpc.remoting.mxml.RemoteObject like so: package remoting { import mx.rpc.remoting.mxml.RemoteObject; public class CustomRemoteObject extends RemoteObject { public function CustomRemoteObject(destination:String=null) { super(destination); } } } However, when doing so and declaring a CustomRemoteObject in MXML as above, the flex compiler shows the error: Could not resolve <mx:method> to a component implementation At first I thought it had something to do with CustomRemoteObject failing to do something, despite that (or since) it had no change except as to the name. So, I copied the source from mx.rpc.remoting.mxml.RemoteObject into CustomRemoteObject and modified it so the only difference was a refactoring of the class and package name. But still, the same error. Unlike many MXML components, I cannot cmd+click <mx:method> in FlashBuilder to open the source. Likewise, I have not found a reference in mx.rpc.remoting.mxml.RemoteObject, mx.rpc.remoting.RemoteObject, or mx.rpc.remoting.AbstractService, and have been unsuccessful in find its source online. Which leads me to the questions in the title: What exactly is <mx:method>? (yes, I know it's a declaration of a RemoteObject method, and I know how to use it, but it's peculiar in regard to other components) Why did my attempt at subclassing RemoteObject fail, despite it effectually being a rename? Perhaps the root, why can mx.rpc.remoting.mxml.RemoteObject as an MXML declaration accept <mx:method> child tags, yet the source of said class cannot when refactored in name only?

  • MS Access Interop - How to set print filename?

    - by Ryan
    Hi all, I'm using Delphi 2009 and the MS Access Interop COM API. I'm trying to figure out two things, but one is more important than the other right now. I need to know how to set the file name when sending the print job to the spooler. Right now it's defaulting to the Access DB's name, which can be something different than the file's name. I need to just ensure that when this is printed it enters the print spool using the same filename as the actual file itself - not the DB's name. My printer spool is actually a virtual print driver that converts documents to an image. That's my main issue. The second issue is how to specify which printer to use. This is less important at the moment because I'm just using the default printer for now. It would be nice if I could specify the printer to use, though. Does anyone know either of these two issues? Thank you in advance. I'll go ahead and paste my code: unit Converter.Handlers.Office.Access; interface uses sysutils, variants, Converter.Printer, Office_TLB, Access_TLB, UDC_TLB; procedure ToTiff(p_Printer: PrinterDriver; p_InputFile, p_OutputFile: String); implementation procedure ToTiff(p_Printer: PrinterDriver; p_InputFile, p_OutputFile: String); var AccessApp : AccessApplication; begin AccessApp := CoAccessApplication.Create; AccessApp.Visible := False; try AccessApp.OpenCurrentDatabase(p_InputFile, True, ''); AccessApp.RunCommand(acCmdQuickPrint); AccessApp.CloseCurrentDatabase; finally AccessApp.Quit(acQuitSaveNone); end; end; end.

  • How to Bind a selected Item in a Listbox to a ItemsControl and ItemTemplate in WPF and C#

    - by Scott
    All, LowDown: I am trying to create a Document Viewer in WPF. The layout is this: Left side is a full list box. On the right side is a Collection or an Items control. Inside the items control will be a collection of the "selected documents" in the list box. So A user can select multiple items in the list box and for each new item they select, they can add the item to the collection on the right. I want the collection to look like a image gallery that shows up in Google/Bing Image searches. Make sense? The problem I am having is I can't get the WPFPreviewer to bind correctly to the selected item in the list box under the itemscontrol. Side Note: The WPFPreviewer is something Micorosft puts out that allows us to preview documents. Other previewers can be built for all types of documents, but im going basic here until I get this working right. I have been successful in binding to the list box WITHOUT the items control here: <Window.Resources> <DataTemplate x:Key="listBoxTemplate"> <StackPanel Margin="3" > <DockPanel > <Image Source="{Binding IconURL}" Height="30"></Image> <TextBlock Text=" " /> <TextBlock x:Name="Title" Text="{Binding Title}" FontWeight="Bold" /> <TextBlock x:Name="URL" Visibility="Collapsed" Text="{Binding Url}"/> </DockPanel> </StackPanel> </DataTemplate> </Window.Resources><Grid Background="Cyan"> <ListBox HorizontalAlignment="Left" ItemTemplate="{StaticResource listBoxTemplate}" Width="200" AllowDrop="True" x:Name="lbDocuments" ItemsSource="{Binding Path=DocumentElements,ElementName=winDocument}" DragEnter="documentListBox_DragEnter" /> <l:WPFPreviewHandler Content="{Binding ElementName=lbDocuments, Path=SelectedItem.Url}"/> </Grid> Though, once I add in the ItemsControl, I can't get it to work anymore: <Window.Resources> <DataTemplate x:Key="listBoxTemplate"> <StackPanel Margin="3" > <DockPanel > <Image Source="{Binding IconURL}" Height="30"></Image> <TextBlock Text=" " /> <TextBlock x:Name="Title" Text="{Binding Title}" FontWeight="Bold" /> <TextBlock x:Name="URL" Visibility="Collapsed" Text="{Binding Url}"/> </DockPanel> </StackPanel> </DataTemplate> </Window.Resources> <Grid> <ListBox HorizontalAlignment="Left" ItemTemplate="{StaticResource listBoxTemplate}" Width="200" AllowDrop="True" x:Name="lbDocuments" ItemsSource="{Binding Path=DocumentElements,ElementName=winDocument}" DragEnter="documentListBox_DragEnter" /> <ItemsControl x:Name="DocumentViewer" ItemsSource="{Binding ElementName=lbDocuments, Path=SelectedItem.Url}" > <ItemsControl.ItemTemplate> <DataTemplate> <Grid Background="Cyan"> <l:WPFPreviewHandler Content="{Binding Url}"/> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </Grid> Can someone please help me out with trying to bind to the ItemsControl if I select one or even multiple items in the listbox.

  • Thinking Sphinx - sorting by a string attribute gets out of sync when changes are made

    - by Scott Brown
    I have a "restaurants" table with a "name" column. I've defined the following index: indexes "REPLACE(UPPER(restaurants.name), 'THE ', '')", :as => :restaurant_name, :sortable => true ... because I want to sort the restaurant names without respect to the prefix "The ". My problem is that whenever one of these records is updated (in any way) the new record jumps to the top of the sort order. If another record is updated, it also jumps ahead of the rest. I end up with two lists: a list of restaurants that have been updated since the last re-indexing and a list of those that haven't. Each respective list is in alphabetical order, but I don't understand why the overall list is getting segregated this way. I do have a delayed delta index set up, and I assume the issue is related to this.

  • Is it possible to have mspec & NUnit tests in a single project

    - by Mike Scott
    I've got a unit test project using NUnit. When I add the mspec (machine.specifications) assembly to the references, both ReSharper and TestDriven.Net stop running the NUnit tests and only run the mspec tests. Is there a way or setting that allows both NUnit & mspec tests to co-exist and run in the same project using R# & TD.Net test runners?

  • How do I stop myself from redesigning my Silverlight screens? Is there a theme that looks like Sket

    - by Dan Ryan
    Whilst working in Silverlight I am always fighting the urge to work on the screen design rather than coding the behaviour (which is what I should be doing). My cunning plan is to find a theme that looks something like MS SketchFlow or Balsamiq which will remind me of the draft nature of the screens whilst being somewhat prettier than the default look & feel of Silverlight. Does anyone know of such a theme? Alternatively can anyone give advise on how they overcame there design addiction :) Thanks, Dan

I have 3 entities, with a relationship as such Entity A <-- Entity B <<-- Entity C I have an NSFetchedResults controller and I'm trying to filter the results of Entity A using the following predicate. [NSPredicate predicateWithFormat:@"NONE entityB.entityC == %@", self.entityC]; When I try and run the app, the output shows no results. I can alter the predicate slightly to: [NSPredicate predicateWithFormat:@"ANY entityB.entityC == %@", self.entityC]; And it shows me only the results that I want it to filter out. Why is this happening?

  • How do I insert an input's value into a separate form?

    - by ryan
    I'm making a tool for my university that allows students to create a list of classes by doing the following: Searching by course title for their course via an autocomplete input field. Adding that course to a separate form that upon being submitted creates a course list. I am trying to link the autocomplete and the course list form with an 'add to course list' button that inserts a hidden input field into the course list form which can subsequently be submitted by a 'create course list' button. My question is this: How do I take the value of the autocomplete input and insert it into the course list form without using AJAX? So far I have something like the following: <%= text_field_with_auto_complete :course, :title, :size => 40 %> <%= link_to_function "Add to Course List" do |page| page.insert_html :top, :course_list, hidden_field(:courses, :course, {:value => "$('course_title').value"}) %> <% form_for(@course_list) do |f|%> <div id="course_list">Insert selected courses here.</div> <% end %>
