  • How do I open a FolderBrowserDialog at the selected folder?

    - by ProfK
    I have a FolderBrowserDialog, displayed with code shown below. However, it keeps opening with 'Computer', i.e. the root of the folder tree, selected. How do I get it to open on the selected folder? var folderBrowser = new FolderBrowserDialog(); folderBrowser.Description = "Select Chase 6 Installation Folder"; folderBrowser.RootFolder = Environment.SpecialFolder.MyComputer; folderBrowser.ShowNewFolderButton = false; if (Directory.Exists(Properties.Settings.Default.defaultChasePath)) { string x = Properties.Settings.Default.defaultChasePath; folderBrowser.SelectedPath = x; } if (folderBrowser.ShowDialog(this) == DialogResult.OK) { chasePathtext.Text = folderBrowser.SelectedPath; }

  • How to parse invalid HTML with Perl?

    - by bodacydo
    I maintain a database of articles with HTML formatting. Unfortunately the editors who wrote articles didn't know proper HTML, so they often have written stuff like: <div class="highlight"><html><head></head><body><p>Note that ...</p></html></div> I tried using HTML::TreeBuilder to parse this HTML but after parsing it and dumping the resulting tree, all the elements between <div class="highlight">...</div> are gone. I'm left with just <div class="highlight"></div>. The editors often have also done things like: <div class="article"><style>@font-face { font-family: "Cambria"; }</style>Article starts here</div> Parsing this with HTML::TreeBuilder results in empty <div class="article"></div> again. Any ideas how to approach this broken HTML and actually make sense out of it?

  • What is the equivalent of OnRender in Silverlight?

    - by John Weldon
    I'm working on porting an app from WPF to Silverlight. The app uses custom types derived from FrameworkElement (in WPF) to describe shapes, and text to be rendered on a Canvas. The WPF app root node overrides OnRender() to iterate through a collection of 'child' nodes, calling Render on each child node to build the Visual Tree. Silverlight doesn't expose OnRender, but there are hints that the same effect can be achieved using ControlTemplate. Is this the way to go, and are there any good examples of using this method available? I've done some googling (binging?) and found nothing really conclusive.

  • Using WPFPerf to profile a WPF 4.0 application doesn't show me any information

    - by Adrian
    I am trying to use WPFPerf to profile a WPF 4.0 application (I have the latest WPFPerf that should work on WPF 4.0 aps). I start the tool Visual Profiler from WPFPerf, I start my aplication, but after that nothing happens and the element tree from the Visual Profiler is empty. No other error message is shown. Can anyone tell me what am I not doint right? As an additional information, when I try to analize my .exe assembly or any other assembly from my application, I get a BadFormatException saying that the assembly was build with a newer version of .NET. From the download page http://go.microsoft.com/fwlink/?LinkID=191420 I see that this version of WPFPerf should be ok for my app

  • UITableView backgroundColor always gray on iPad

    - by rjobidon
    Hi, When I set the backgroundColor for my UITableView it works fine on iPhone (device and simulator) but NOT on the iPad simulator. Instead I get a light gray background for any color I set including groupTableViewBackgroundColor. Steps to reproduce: Create a new navigation-based project. Open RootViewController.xib and set the table view style to "Grouped". Add this responder to the RootViewController:- (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor blackColor]; } Select Simulator SDK 3.2, build and run. You will get a black background (device and simulator). Select your target in the project tree. Click on Project : Upgrade Current Target for iPad. Build and run. You will get a light gray background. Revert the table view style to Plain and you will get a black background. Thanks for your help!

  • Complex reporting on subversion (possibly Export Subversion log into database for reporting)

    - by James A. N. Stauffer
    What is the best way to do complex reporting on subversion logs like the following for each file? file, directory, last revision date, previous revision date(where revision date is at least 30 older than last), days diff(between revision dates) Since Subversion allows on revision to change multiple files I assume svn log needs to be run against each file individually. Ideas (that don't seem very good): Shell scripting to produce a csv file to be imported to a DB. The following is a start but doesn't show the filename: find . -name "." -print | xargs -l svn log -l 2 Shell scripting to produce XML and then use XSLT to create CSV to import to a DB. It might use a similar command to above but would still have some of the same limitation. Write a program to just parse the log on the whole directory tree, make one insert to DB per revision/file combination, and then query the DB.

  • How to retrieve all the records from a Berkeley DB in Ruby

    - by Federico Builes
    I'd like to be able to get all the key-values stored in a Berkeley DB using the Ruby bindings from http://github.com/mattbauer/bdb/tree/master but I'm not sure how to proceed. Any pointers will be appreciated. UPDATE Here's a small script that loops over the keys and prints them. Based on Pax' answer: require 'rubygems' require 'bdb' env = Bdb::Env.new(0) env.open('foo', Bdb::DB_CREATE,0) db = env.db db.open(nil, 'db1.db', nil, Bdb::Db::BTREE, Bdb::DB_CREATE,0) db.put(nil, 'key', 'value', 0) db.put(nil, 'key1', 'value1', 0) db.put(nil, 'key2', 'value2', 0) dbc = db.cursor(nil,0) key,val = dbc.get(nil,nil,Bdb::DB_FIRST) while key p key,val key,val = dbc.get(nil,nil,Bdb::DB_NEXT) end dbc.close db.close(0) env.close

  • JMeter to grab full querystring into a variable for future use

    - by jfbauer
    Someone provided me the regex to parse out a query string: (?<=\?)[^?]+$ I am trying to use that in JMeter with no luck (although I am successful in pulling out individual query string parameter values based on various example postings on the web). I created a regular expression extractor called "Grab QueryString". I selected the URL response field to check. For the reference name, I typed "myQueryString". For the regular expression, I entered your text. For template, I entered $1$ Match no = 1 Default Value = ERROR Unfortunately, "myQueryString" is getting populated with ERROR and not the URL query string as hoped when I try and use it as a parameter in a future GET. Thus, I see this in the "View Results Tree": https:/www.website.com/folder/page.aspx?ERROR Instead of: https:/www.website.com/folder/page.aspx?jfhjHSDjgdjhsjhsdhjSJHWed Did I do something wrong? Anyone have any suggestions?

  • intercept RelativeSource FindAncestor

    - by Pradeep
    I have a WPF application which runs as a excel plugin, it has its visual tree like so Excel ElementHost WPF UserControl WPF ribbon bar control Now any controls sitting on the WPF ribbon bar control are not enabled when the plugin is loaded within excel. See error below System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Window', AncestorLevel='1''. BindingExpression:Path=IsActive; DataItem=null; target element is 'Ribbon' (Name=''); target property is 'NoTarget' (type 'Object') If I nest the ribbon bar control in a standalone Window(outside excel) it works fine. Is there a way to intercept the FindAncestor call for a Window and wire it to something else.? Note that I cannot change the above binding as it isn't my control.

  • What is the "standard" JQuery treeview that most people use? It seems the most popular plugin isn't

    - by Pete Alvin
    I've chosen JQuery as my JavaScript library but now I'm a bit frustrated by the JQuery plugin site... the site kinda sucks... the plugin area isn't designed very well and I can only find a few treeviews. The one with the most votes (link text) isn't supported anymore. Can someone please point me to an industrial strength treeview? Desired Features: 1. stable 2. async / ajax would be nice 3. drag and drop nodes would be nice I've been delighted so far with JQueryUI--nice design. But, how come it doesn't come with a standard tree view? Pete

  • Text mining with PHP

    - by garyc40
    Hi, I'm doing a project for a college class I'm taking. I'm using PHP to build a simple web app that classify tweets as "positive" (or happy) and "negative" (or sad) based on a set of dictionaries. The algorithm I'm thinking of right now is Naive Bayes classifier or decision tree. However, I can't find any PHP library that helps me do some serious language processing. Python has NLTK (http://www.nltk.org). Is there anything like that for PHP? I'm planning to use WEKA as the back end of the web app (by calling Weka in command line from within PHP), but it doesn't seem that efficient. Do you have any idea what I should use for this project? Or should I just switch to Python? Thanks

  • How to Animate a Gradient on a Path to visualize data flow in WPF/WCF app

    - by John
    I have an interesting project where several "nodes" on a cnavas are connected via a Path similiar to a mindmap tree. The path is used to visualize the connection state between two nodes. Red means the nodes are disconnected, green means they're connected. The next step would be to illustrate data flow (from A to B or B to A) using that path and an animation. Basically I would want to start the animation with the data transfer and stop it when the transfer is complete. Does anyone know how this could be done in WPF?

  • Antlr question: cannot get Antlr tool to compile simple file from ANTLRWorks

    - by Don Henton
    Here is the grammar file: grammar fred; test : 'fred'; Here is the batch file to launch the tool: SET JAVA_HOME=C:\Program Files\Java\jdk1.6.0_24 SET PATH=%PATH%;%JAVA_HOME%\bin SET ANTLR_HOME=c:/users/don/workspace/antlrAssign/lib/ java -cp %ANTLR_HOME%/antlr-3.3-complete.jar antlr.Tool fred.g Here's the result: ANTLR Parser Generator Version 2.7.7 (20060906) 1989-2005 fred.g:1:1: unexpected token: grammar error: Token stream error reading grammar(s): fred.g:3:19: expecting ''', found 'r' fred.g:1:1: rule grammar trapped: fred.g:1:1: unexpected token: grammar TokenStreamException: expecting ''', found 'r' Prior postings refer to "org.antlr.Tool" but the 3.3 jar has it located as above. The idea was to create a debug version of a tree parser, and according to the documentation, you have to use the command line tool. Has anyone seen this before? Am I nuts? It's two lines long and its dying on the first word in the file. Of course this compiles in antlrworks. Any help appreciated, I can't afford any more adjustments to my medications.

  • Howto bind a RoutedCommand in a child?

    - by Wouter
    I am having trouble binding a Command that is generated up the UI tree to a control. The following example illustrates my point, the CommandBinding in Grid does not act on the InputBindings in Window. Maybe I do not understand the point of commands, but I would like to have a nice solution for child controls to act on user input on the Window (any control on the Window). <Window x:Class="SilverFit.Menu.Wpf.WpfWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Window.InputBindings> <KeyBinding Command="Close" Key="Escape"/> <MouseBinding Command="Close" MouseAction="RightClick" /> </Window.InputBindings> <Grid Name="grid"> <Grid.CommandBindings> <CommandBinding Command="Close" Executed="Close"/> </Grid.CommandBindings> </Grid> </Window>

  • Error when importing com.google, com.android.internal.Telephony, etc.

    - by psyhclo
    Hey, I've downloaded the android source code for CallLog, Contacts, Dialing in this link http://android.git.kernel.org/?p=platform/packages/apps/Contacts.git;a=tree But now, when I try to import this package on Eclipse, imports like: com.google, com.android.internal.Telephony, com.android.internal.R, com.google.android.collect, android.provider.ContactsContract.Intents.UI, android.provider.ContactsContract.SearchSnippetColumns, android.provider.ContactsContract.ProviderStatus, android.provider.ContactsContract.ContactCounts, android.content.IContentService, android.provider.ContactsContract.Intents.UI And many other imports, show errors saying it cannot be resolved. So my question is, why it shows this errors? Why I cant implement it without this errors? I use the Google APIs, I've created the project from an existing source code, but I dont know why this happens. Thanks.

  • z-Index overlay in google maps version 3

    - by fredrik
    Hi, I'm trying to get an overlay in google maps api v3 to appear above all markers. But it seems that the google api always put my overlay with lowest z-index priority. Only solution i've found is to iterate up through the DOM tree and manually set z-index to a higher value. Poor solution. I'm adding my a new div to my overlay with: onclick : function (e) { var index = $(e.target).index(), lngLatXYposition = $.view.overlay.getProjection().fromLatLngToDivPixel(this.getPosition()); icon = this.getIcon(), x = lngLatXYposition.x - icon.anchor.x, y = lngLatXYposition.y - icon.anchor.y $('<div>test</div>').css({ left: x, position: 'absolute', top: y + 'px', zIndex: 1000 }).appendTo('.overlay'); } I've tried every property I could think of while creating my overlay. zIndex, zPriority etc. I'm adding my overlay with: $.view.overlay = new GmapOverlay( { map: view.map.gmap }); And GmapOverlay inherits from new google.maps.OverlayView. Any ideas? ..fredrik

  • Sub-classing TreeView in C# WinForms for mouse over tool tips

    - by Matt
    Ok, this is a weird one. The expected behaviour for a TreeView control is that, if ShowNodeToolTips is set to false, then, when a label for a tree node exceeds the width of the control (or, more accurately, it's right hand edge is past the right hand edge of the client area), then a tooltip is shown above the node showing the full item's text. I'd like to disable that, because the above semantic doesn't always work, depending on what the treeview is contained within. So I have rolled my own, and got the tooltips to work (and line up better than the default one!) - but I would like to be able to disable the 'default' behaviour for situations where it would work natively. So, can anyone point me in the right direction as to which message to post to the TreeView in order to disable that behaviour? I have looked at the windows control reference, but couldn't find anything that looked like it might be the one. Thanks Matt

  • SQL server recursive query error.The maximum recursion 100 has been exhausted before statement completion

    - by ienax_ridens
    I have a recursive query that returns an error when I run it; in other databases (with more data) I have not the problem. In my case this query returns 2 colums (ID_PARENT and ID_CHILD) doing a recursion because my tree can have more than one level, bit I wanna have only "direct" parent. NOTE: I tried to put OPTION (MAXRECURSION 0) at the end of the query, but with no luck. The following query is only a part of the entire query, I tried to put OPTION only at the end of the "big query" having a continous running query, but no errors displayed. Error have in SQL Server: "The statement terminated.The maximum recursion 100 has been exhausted before statement completion" The query is the following: WITH q AS (SELECT ID_ITEM, ID_ITEM AS ID_ITEM_ANCESTOR FROM ITEMS_TABLE i JOIN ITEMS_TYPES_TABLE itt ON itt.ID_ITEM_TYPE = i.ID_ITEM_TYPE UNION ALL SELECT i.ID_ITEM, q.ID_ITEM_ANCESTOR FROM q JOIN ITEMS_TABLE i ON i.ID_ITEM_PADRE = q.ID_ITEM JOIN ITEMS_TYPES_TABLE itt ON itt.ID_ITEM_TYPE = i.ID_ITEM_TYPE) SELECT ID_ITEM AS ID_CHILD, ID_ITEM_ANCESTOR AS ID_PARENT FROM q I need a suggestion to re-write this query to avoid the error of recursion and see the data, that are few.

  • Common lisp error: "should be lambda expression"

    - by Zachary
    I just started learning Common Lisp a few days ago, and I'm trying to build a function that inserts a number into a tree. I'm getting an error, * - SYSTEM::%EXPAND-FORM: (CONS NIL LST) should be a lambda expression From googling around, it seems like this happens when you have too many sets of parenthesis, but after looking at this for an hour or so and changing things around, I can't figure out where I could be doing this. This is the code where it's happening: (defun insert (lst probe) (cond ((null lst) (cons probe lst)) ((equal (length lst) 1) (if (<= probe (first lst)) (cons probe lst) (append lst (list probe)))) ((equal (length lst) 2) ((cons nil lst) (append lst nil) (insertat nil lst 3) (cond ((<= probe (second lst)) (insert (first lst) probe)) ((> probe (fourth lst)) (insert (fifth lst) probe)) (t (insert (third lst) probe))))))) I'm pretty sure it's occurring after the ((equal (length lst) 2), where the idea is to insert an empty list into the existing list, then append an empty list onto the end, then insert an empty list into the middle.

  • Calling Entity Framework function import from code

    - by Mikey Cee
    So I have a stored procedure called Spr_EventLogCreate defined in my database. I have created a function import in my data model called LogEvent with no return type, and I can see this function in the Model Browser tree at MyModel.edmx MyModel EntityContainer Function Imports LogEvent. I thought I should then be able to call the function in my code as follows: var context = new MyModelEntities(); context.LogEvent(...); But the LogEvent() method is not present. I must be being really stupid here, but how do I call my imported function? Using VS 2008 and EF 3.5.

  • Opening a local file in Eclipse from the web

    - by Victor Nicollet
    Right now, when I notice a problem on a page on my PHP web site, I have to look at the URL, mentally deduce what file is responsible for displaying that page, then navigate the Eclipse PDT file tree to open that file. This is annoying and uses brain power that could have been applied to solving the issue instead. I would like my PHP web site to display on every page a link that I could click to automatically open the correct file in Eclipse. I can easily compute the complete absolute path for the file I need to open (for example, open C:/xampp/htdocs/controllers/Foo/Bar.php when visiting /foo/bar), and I can make sure that Eclipse is currently open with the correct project loaded, but I'm stuck on how I can have Firefox/Chrome/IE tell Eclipse to open that specific file.

  • Large svn external

    - by MPelletier
    I have a project which uses a large library residing in its own repository. Using: Tortoise-SVN, the server is running an enterprise edition of VisualSVN The project itself has the "standard" structure: trunk tags branches In each branch, tag, and trunk is the library, set as an external (svn:external property). If I get the entire tree, I get the library several times, which is just getting too ridiculously repetitive. Is there a recommended structure for this? Or perhaps a way not to get all externals (because other externals are much smaller, easier to manipulate)?

  • [ext js] Renderer for ColumnTree?

    Hello! I'm trying to add a custom renderer to a ColumnTree in Ext JS. Since it appears(?) that this isn't supported, does anyone know of any workaround to use a renderer? Here's a snippet of code - let's just say (hypothetically) that I have a renderer I'd like to use for the documentsVersion tab below - does anyone have any ideas? return new Ext.tree.ColumnTree({ autoHeight: false, rootVisible: showRoot, autoScroll: false, id: (!treeId)? window.mainTreeId: treeId, loader: (!loader)?window.docTreeLoader:loader, columns: [{ header:"${documentsTitle}", width: windowWidth * 0.40 }, { header:"${documentsVersion}", width: windowWidth * 0.10, dataIndex:'version' }, Thanks!

Configuration of the build tree fails. I am using the cmake-gui since I have never tried to compile using cmake it's possible it could be something in there.
