  • C#, Open Folder and Select multiple files

    - by Vytas999
    Hello, in C# I want to open explorer and in this explorer window must be selected some files. I do this like that: string fPath = newShabonFilePath; string arg = @"/select, "; int cnt = filePathes.Count; foreach (string s in filePathes) { if(cnt == 1) arg = arg + s; else { arg = arg + s + ","; } cnt--; } System.Diagnostics.Process.Start("explorer.exe", arg); But only the last file of "arg" is selected. How to make that all files of arg would be selected, when explorer window is opened..?

  • Asynchronous Html.ImageGetter for setting multiple images in a TextView

    - by thedude19
    I'm writing an application that takes HTML pages and parses them to display on the screen. Specifically, this application pulls HTML from a message board and lists posts made by users. The problem is that a lot of the content in posts are pictures in <img> tags, so I need to write a Html.ImageGetter to handle the downloading of the images. My textView.setText() method will look like this: myTextView.setText(Html.fromHtml(myText, new ImageGetter() { @Override public Drawable getDrawable(String source) { Drawable d; // Need to async download image here return d; } }, null)); Doing this synchronously is trivial, but is there a suggested way to do this asynchronously so that it doesn't lock up my UI thread? I would also like to eventually build in caching of these images, but I imagine that would be pretty simple once the async downloading was there.

  • Prolog: permutations check and multiple answers

    - by Adrian
    Continuing to learn prolog, I'm trying to write a permutation(L1, L2) predicate. It should return true, only if L1 can be made up of all elements in L2. My code so far is the following: permutation([], []). permutation([H|T], L2) :- remove(L2, H, R), permutation(T, R). Assuming that the predicate remove(L1, X, R) functions correctly, and it removes X from L1, I do not get correct results: ?- permutation([1],[1]). true ; false. ?- permutation([1, 2],[1]). true ; false. ?- permutation([1, 2],[1, 2]). true ; false. ?- permutation([1],[1, 2]). false. What am I missing. Subquestion: What happens when the remove predicate returns two answers? My implementation returns the new, correct list, and then after pressing ; it returns the original list. Which answer does permutation predicate use? ?- remove([1,2,3], 3, R). R = [1, 2] ; R = [1, 2, 3].

  • Wordpress SQL Select Multiple Meta Values / Meta Keys / Custom Fields

    - by Wes
    I am trying to modify a wordpress / MySQL function to display a little more information. I'm currently running the following query that selects the post, joins the 'postmeta' and gets the info where the meta_key = _liked function most_liked_posts($numberOf, $before, $after, $show_count) { global $wpdb; $request = "SELECT ID, post_title, meta_value FROM $wpdb->posts, $wpdb->postmeta"; $request .= " WHERE $wpdb->posts.ID = $wpdb->postmeta.post_id"; $request .= " AND post_status='publish' AND post_type='post' AND meta_key='_liked' "; $request .= " ORDER BY $wpdb->postmeta.meta_value+0 DESC LIMIT $numberOf"; $posts = $wpdb->get_results($request); foreach ($posts as $post) { $post_title = stripslashes($post->post_title); $permalink = get_permalink($post->ID); $post_count = $post->meta_value; echo $before.'<a href="' . $permalink . '" title="' . $post_title.'" rel="nofollow">' . $post_title . '</a>'; echo $show_count == '1' ? ' ('.$post_count.')' : ''; echo $after; } } The important part being: $post_count = $post->meta_value; But now I want to also grab a value that is attached to each post called wbphoto How do I specify that $post_count = _liked and $photo = wbphoto ? Here is a screen cap of my Phpmyadmin

  • Chaining multiple MapReduce jobs in Hadoop.

    - by Niels Basjes
    In many real-life situations where you apply MapReduce, the final algorithms end up being several MapReduce steps. I.e. Map1 , Reduce1 , Map2 , Reduce2 , etc. So you have the output from the last reduce that is needed as the input for the next map. The intermediate data is something you (in general) do not want to keep once the pipeline has been successfully completed. Also because this intermediate data is in general some data structure (like a 'map' or a 'set') you don't want to put too much effort in writing and reading these key-value pairs. What is the recommended way of doing that in Hadoop? Is there a (simple) example that shows how to handle this intermediate data in the correct way, including the cleanup afterward? Thanks.

  • ibatis isNotEmpty with multiple variables

    - by hibernate
    Suppose I have a massive table called inactiveUsers and a search form. I want to conditionally join the inactiveUsers table if any user related characteristic is chosen (address, name, phoneNumber, etc...). Is there any way to do this without the following: <isNotEmpty property="address">JOIN inactiveUsers</isNotEmpty> <isNotEmpty property="phoneNumber">JOIN inactiveUsers</isNotEmpty> <isNotEmpty property="name">JOIN inactiveUsers</isNotEmpty> and so on for another 10-20 isNotEmpty clauses. I would like to do something like: <isAnyNotEmpty properties="address, phoneNumber, name, ....">JOIN inactiveUsers</isNotEmpty> Is this possible with ibatis? If so, how?

  • Multiple JOIN and SELECT Statements from eight tables

    - by user1486004
    I am trying to make an SQL statement that takes eight different numbers and searches eight different tables from one database for the corresponding value. I keep getting invalid syntax, but I can't figure out why. Here is my code: SELECT cable_length.ID, drawing.ID, optional.ID, output_type.ID, pressure_range.ID, pressure_type.ID, series.ID, termination.ID FROM ( SELECT value AS cable_length FROM A1 WHERE A1.id = %s JOIN SELECT value AS drawing FROM A2 WHERE A2.id = %s, JOIN SELECT value AS optional FROM A3 WHERE A3.id = %s, JOIN SELECT value AS output_type FROM A4 WHERE A4.id = %s, JOIN SELECT value AS pressure_range FROM A5 WHERE A5.id = %s, JOIN SELECT value AS pressure_type FROM A6 WHERE A6.id = %s, JOIN SELECT value AS series FROM A7 WHERE A7.id = %s, JOIN SELECT value AS termination FROM A8 WHERE A8.id = %s ); The %s will be changed to numbers only. The column name in each database is "ID" and "Value". I want to search by "ID" and return "Value". Any help is greatly appreciated.

  • Transactions in codeigniter with multiple tables.

    - by Ethan
    Hey SO, I'm new to transactions in general, but especially with CodeIgniter. I'm using InnoDB and everything, but my transactions aren't rolling back when I want them to. Here's my code (slightly simplified). $dog_db = $this->load->database('dog', true); $dog_db->trans_begin(); $dog_id = $this->dogs->insert($new_dog); //Gets primary key of insert if(!$dog_id) { $dog_db->trans_rollback(); throw new Exception('We have had an error trying to add this dog. Please go back and try again.'); } $new_review['dog_id'] = $dog_id; $new_review['user_id'] = $user_id; $new_review['date_added'] = time(); if(!$this->reviews->insert($new_review)) //If the insert fails { $dog_db->trans_rollback(); throw new Exception('We have had an error trying to add this dog. Please go back and try again.'); } //ADD DESCRIPTION $new_description['description'] = $add_dog['description']; $new_description['dog_id'] = $dog_id; $new_description['user_id'] = $user_id; $new_description['date_added'] = time(); if(!$this->descriptions->insert($new_description)) { $dog_db->trans_rollback(); throw new Exception('We have had an error trying to add this dog. Please go back and try again.'); } $booze_db->trans_rollback(); //THIS IS JUST TO SEE IF IT WORKS throw new Exception('We have had an error trying to add this dog. Please go back and try again.'); $booze_db->trans_commit(); } catch(Exception $e) { echo $e->getMessage(); } I'm not getting any error messages, but it's not rolling back either. It should roll back at that final trans_rollback right before the commit. My models are all on the "dog" database, so I think that the transaction would carry into the models' functions. Maybe you just can't use models like this. Any help would be greatly appreciated! Thanks!

  • Looping to provide multiple lines in linechart (django-googlecharts)

    - by mighty_bombero
    Hi, I'm trying to generate some charts using django-googlecharts. This works fine for rather static data but in one case I would like to render a different number of lines, based on a variable. I tried this: {% chart %} {% for line in line_data %} {% chart-data line %} {% endfor %} {% chart-size "390x200" %} {% chart-type "line" %} {% chart-labels days %} {% endchart %} Line data is a list containing lists. The template code fails with "Caught an exception while rendering: max() arg is an empty sequence". I guess the problem is that I try to loop over templatetags. What approach could be used here? Or am I completely missing something? Is this doable using inclusion tags? Thanks for your help.

  • newline-ignoring diff / diff across multiple lines / reflow-ignoring diff

    - by Adam
    Does anybody know of a diff-like tool that can show me the changes between two text files, but ignore changes in whitespace including newlines? Here's an example: the quick brown fox jumped over the lazy bear. the quick brown fox jumped over the lazy bear. the quick brown fox jumped over the lazy bear. the quick brown fox jumped over the lazy bear. quick brown fox jumped over the lazy bear. the quick brown fox jumped over the lazy bear. the quick brown fox jumped over the lazy bear. the quick brown fox jumped over the lazy bear. All I did was delete one word and reflow it, but "diff -b" detects a change on every line (as it should; I'm not saying this is a bug in diff). But for large LaTeX files this is a major problem; change one word in a long paragraph and the diff you get back is basically useless. By the way, I'm aware that this requires way more computational power than the usual lines-are-atomic diff. I'm only doing this on small human-generated files and am happy to wait a long time if I have to.

  • AbcPDF renders the same page multiple times

    - by Steven
    I need to retrieve several pages and output this in a PDF document. I have the following page structure: Page 1 Sub 1 Sub 2 Sub 3 On page one, I have a link which executes the below code. What it does, is to retrieve child pages (one level) and put them in a page collection. Then I loop trough the page collection and retrieve each sub pages URL. This works. I've tested and seen that it retrieves 3 different URL's. The problem is that my PDF gets three pages of Page 1. It does not render Sub 1 to 3. Why isn't docID = document.AddImageUrl(pageLink) retrieving the pages? Websupergoo refers to a caching problem which may occur. But their solution did not help me. Any good suggestions anyone? protected void linkBtnCreateMultipagePDF_Click(object sender, EventArgs e) { string baseURL = Request.Url.ToString(); PageDataCollection pdc = GetChildren(CurrentPageLink); //Create PDF document Doc document = new Doc(); document.Rect.Inset(10, 20); int docID; string pageLink = string.Empty; foreach (PageData pd in pdc) { //This lops goes through the different pages and retrieves that pages URL pageLink = baseURL + pd.LinkURL; document.Page = document.AddPage(); // But for some reason, the same page is added here. docID = document.AddImageUrl(pageLink); //Chain pages together while (true) { if (!document.Chainable(docID)) break; document.Page = document.AddPage(); docID = document.AddImageToChain(docID); } } //Flatten file for (int i = 1; i <= document.PageCount; i++) { document.PageNumber = i; document.Flatten(); } byte[] theData = document.GetData(); Response.Clear(); Response.ContentType = "application/pdf"; Response.AddHeader("content-disposition", "inline; filename=MyPDF.PDF"); Response.AddHeader("content-length", theData.Length.ToString()); Response.BinaryWrite(theData); Response.End(); }

  • Preloading multiple comboboxes/listbox itemssource with enumerated values using WCF RIA Services

    - by Dale Halliwell
    I would like to be able to load several RIA entitysets in a single call without chaining/nesting several small LoadOperations together so that they load sequentially. I have several pages that have a number of comboboxes on them. These comboboxes are populated with static values from a database (for example status values). Right now I preload these values in my VM by one method that strings together a series of LoadOperations for each type that I want to load. For example: public void LoadEnums() { context.Load(context.GetMyStatusValues1Query()).Completed += (s, e) => { this.StatusValues1 = context.StatusValues1; context.Load(context.GetMyStatusValues2()).Completed += (s1, e1) => { this.StatusValues2 = context.StatusValues2; context.Load(context.GetMyStatusValues3Query()).Completed += (s2, e2) => { this.StatusValues3 = context.StatusValues3; (....and so on) }; }; }; }; While this works fine, it seems a bit nasty. Also, I would like to know when the last loadoperation completes so that I can load whatever entity I want to work on after this, so that these enumerated values resolve properly in form elements like comboboxes and listboxes. (I think) I can't do this easily above without creating a delegate and calling that on the completion of the last loadoperation. So my question is: does anyone out there know a better pattern to use, ideally where I can load all my static entitysets in a single LoadOperation?

  • ext-js chart, multiple series on same chart

    - by user121196
    Ext-js Chart, I have a line graph, and I wish to add a single line(eg. average line) to the graph. The only way I can think of to emulate this line is to do the following: add an extra field with identical value to all my data points if, but this seems to be a waste and plus I don't want to show the dots that comes with the line. is there anyway to add an average line to my existing chart?

  • Zoom on multiple areas in d3.js

    - by t2k32316
    I'm planning to have a geoJSON map inside my svg alongside other svg elements. I would like to be able to zoom (zoom+pan) in the map and keep the map in the same location with a bounding box. I can accomplish this by using a clipPath to keep the map within a rectangular area. The problem is that I also want to enable zooming and panning on my entire svg. If I do d3.select("svg").call(myzoom); this overrides any zoom I applied to my map. How can I apply zoom to both my entire svg and to my map? That is, I want to be able to zoom+pan on my map when my mouse is in the map's bounding box, and when the mouse is outside the bounding box, zoom+pan on the entire svg. Here's example code: http://bl.ocks.org/nuernber/aeaac0e8edcf7ca93ade. (how do I get around the cross domain issue to load the map?) <svg id="svg" width="640" height="480" xmlns="http://www.w3.org/2000/svg" version="1.1"> <defs> <clipPath id="rectClip"> <rect x="150" y="25" width="400" height="400" style="stroke: gray; fill: none;"/> </clipPath> </defs> <g id="outer_group"> <circle cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red" /> <g id="svg_map" style="clip-path: url(#rectClip);"> </g> </g> </svg><br/> <script type="text/javascript"> var svg = d3.select("#svg_map"); var mapGroup = svg.append("g"); var projection = d3.geo.mercator(); var path = d3.geo.path().projection(projection); var zoom = d3.behavior.zoom() .translate(projection.translate()) .scale(projection.scale()) .on("zoom", zoomed); mapGroup.call(zoom); var pan = d3.behavior.zoom() .on("zoom", panned); d3.select("svg").call(pan); mapGroup.attr("transform", "translate(200,0) scale(2,2)"); d3.json("ne_110m_admin_0_countries/ne_110m_admin_0_countries.geojson", function(collection) { mapGroup.selectAll("path").data(collection.features) .enter().append("path") .attr("d", path) .attr("id", function(d) { return d.properties.name.replace(/\s+/g, "")}) .style("fill", "gray").style("stroke", "white").style("stroke-width",1); } ); function panned() { var x = d3.event.translate[0]; var y = d3.event.translate[1]; d3.select("#outer_group").attr("transform", "translate("+x+","+y+") scale(" + d3.event.scale + ")"); } function zoomed() { previousScale = d3.event.scale; projection.translate(d3.event.translate).scale(d3.event.scale); translationOffset = d3.event.translate; mapGroup.selectAll("path").attr("d", path); } </script>

  • Multiple calls with Simple Modal OSX Style Dialog

    - by Brad Langdon
    I am using Simple Modal, the OSX style version. I have two calls to the modal and therefore two versions of content. When either of the buttons is clicked it selects only the first lot of content. There is nowhere to put a hook on the content like most modal windows as there is no javascript on the page to add parameters... only an external .js file which I don't want to touch for obvious reasons. Can anyone help me with this problem? Click here to view the page

  • Multiple update panels and multiple postbacks cause entire page to refresh...

    - by Matt
    I'm having the same problem I had yesterday... The solution Aristos provided helped solve the problem, but I have other places sending updatepanel postbacks causing the same problem. When an update panel is updated and another request for an update is called before it has a chance to render the first updates, the entire page refreshes instead of just the update panel. I used fiddler to see what was going on and here's what happens... If I wait for the request to return before doing another request I get this: 21443|updatePanel|dnn_ctr1107_CRM_SalesTool_LeadsUpdatePanel| But if I don't wait, I get this: 66|pageRedirect||http://mysite.com/salesdashboard.aspx| The code from the previous question is still the same except I added UpdateMode="Conditional" to the update panel. Any ideas? Or is the only solution to this making sure that 2+ updates for any number of update panels (as long as they're on the same page) never happen? Thanks, Matt

  • Upload multiple Images and Ping an address to upload them

    - by azz0r
    Hello! I am trying to allow administrators to upload 20-30 images in one go. I have tried jquery uploadify, SWFUpload and other various jquery scripts. However I have had many issues doing this. Uploadify worked fine, however it stopped working and after a day of debugging I couldn't figure out why (and by god, I tried to figure out why) So I have decided to try a java applet, however they all seem to cost quite abit of money. All I need is something to select some images, then each image upload pings and address where I can resize them in PHP, and done. Does anyone know a freeware solution thats easy to use?

  • Refactoring multiple interfaces to a common interface using MVVM, MEF and Silverlight4

    - by Brian
    I am just learning MVVM with MEF and already see the benefits but I am a little confused about some implementation details. The app I am building has several Models that do the same with with different entities (WCF RIA Services exposing a Entity framework object) and I would like to avoid implementing a similar interface/model for each view I need and the following is what I have come up with though it currently doesn't work. The common interface has a new completed event for each model that implements the base model, this was the easiest way I could implement a common class as the compiler did not like casting from a child to the base type. The code as it currently sits compiles and runs but the is a null IModel being passed into the [ImportingConstructor] for the FaqViewModel class. I have a common interface (simplified for posting) defined as follows, this should look familiar to those who have seen Shawn Wildermuth's RIAXboxGames sample. public interface IModel { void GetItemsAsync(); event EventHandler<EntityResultsArgs<faq>> GetFaqsComplete; } A base method that implements the interface public class ModelBase : IModel { public virtual void GetItemsAsync() { } public virtual event EventHandler<EntityResultsArgs<faq>> GetFaqsComplete; protected void PerformQuery<T>(EntityQuery<T> qry, EventHandler<EntityResultsArgs<T>> evt) where T : Entity { Context.Load(qry, r => { if (evt == null) return; try { if (r.HasError) { evt(this, new EntityResultsArgs<T>(r.Error)); } else if (r.Entities.Count() > 0) { evt(this, new EntityResultsArgs<T>(r.Entities)); } } catch (Exception ex) { evt(this, new EntityResultsArgs<T>(ex)); } }, null); } private DomainContext _domainContext; protected DomainContext Context { get { if (_domainContext == null) { _domainContext = new DomainContext(); _domainContext.PropertyChanged += DomainContext_PropertyChanged; } return _domainContext; } } void DomainContext_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e) { switch (e.PropertyName) { case "IsLoading": AppMessages.IsBusyMessage.Send(_domainContext.IsLoading); break; case "IsSubmitting": AppMessages.IsBusyMessage.Send(_domainContext.IsSubmitting); break; } } } A model that implements the base model [Export(ViewModelTypes.FaqViewModel, typeof(IModel))] public class FaqModel : ModelBase { public override void GetItemsAsync() { PerformQuery(Context.GetFaqsQuery(), GetFaqsComplete); } public override event EventHandler<EntityResultsArgs<faq>> GetFaqsComplete; } A view model [PartCreationPolicy(CreationPolicy.NonShared)] [Export(ViewModelTypes.FaqViewModel)] public class FaqViewModel : MyViewModelBase { private readonly IModel _model; [ImportingConstructor] public FaqViewModel(IModel model) { _model = model; _model.GetFaqsComplete += Model_GetFaqsComplete; _model.GetItemsAsync(); // Load FAQS on creation } private IEnumerable<faq> _faqs; public IEnumerable<faq> Faqs { get { return _faqs; } private set { if (value == _faqs) return; _faqs = value; RaisePropertyChanged("Faqs"); } } private faq _currentFaq; public faq CurrentFaq { get { return _currentFaq; } set { if (value == _currentFaq) return; _currentFaq = value; RaisePropertyChanged("CurrentFaq"); } } public void GetFaqsAsync() { _model.GetItemsAsync(); } void Model_GetFaqsComplete(object sender, EntityResultsArgs<faq> e) { if (e.Error != null) { ErrorMessage = e.Error.Message; } else { Faqs = e.Results; } } } And then finally the Silverlight view itself public partial class FrequentlyAskedQuestions { public FrequentlyAskedQuestions() { InitializeComponent(); if (!ViewModelBase.IsInDesignModeStatic) { // Use MEF To load the View Model CompositionInitializer.SatisfyImports(this); } } [Import(ViewModelTypes.FaqViewModel)] public object ViewModel { set { DataContext = value; } } }

  • Multiple skins in ASP.NET MVC using StringTemplate

    - by Jamie
    I am considering the StringTemplate view engine for my ASP.NET MVC application. This application will be built with one skin, but I then expect many more, often very similar skins to be developed for it. This is primiarly the reason for my choice of StringTemplate as the view engine, as there will be zero logic in the views. In my head, I envisaged having each skin in a directory under the 'Views' directory in the folder structure, then maintaining a data structure which maps hostnames to skin directories. An obvious disadvantage of this approach is that I will have to explicitly specify my view files - an alternative might be to hack the implementation of the View() method to change the /views/controller/action standard path and insert an extra layer. Is anyone aware of any examples of implementations along these lines using ASP.NET MVC and StringTemplate at present? Can anyone forsee any potential problems with my approach? Thanks in advance.

  • SQLPlus - spooling to multiple files from PL/SQL blocks

    - by FrustratedWithFormsDesigner
    I have a query that returns a lot of data into a CSV file. So much, in fact, that Excel can't open it - there are too many rows. Is there a way to control spool to spool to a new file everytime 65000 rows have been processed? Ideally, I'd like to have my output in files named in sequence, such as large_data_1.csv, large_data_2.csv, large_data_3.csv, etc... I could use dbms_output in a PL/SQL block to control how many rows are output, but then how would I switch files, as spool does not seem to be accessible from PL/SQL blocks? (Oracle 10g)

  • strange multiple files download - NSURLConnection

    - by Georg
    hi all, I encounter a problem by following your comment. I would like to download different file at same time with different delegate: .h: NSMutableData *fileData; .m: NSString *imgfile = [NSString stringWithFormat:@"http://xxxx/01.jpg"]; NSURL *fileURL1 = [NSURL URLWithString:imgfile]; NSString *audiofile = [NSString stringWithFormat:@"http://xxxx/01.mp3"]; NSURL *fileURL2 = [NSURL URLWithString:audiofile]; NSURLRequest *request1 = [NSURLRequest requestWithURL:fileURL1 cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10.0 ]; NSURLRequest *request2 = [NSURLRequest requestWithURL:fileURL2 cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10.0 ]; NSArray *connections = [[NSArray alloc] initWithObjects: [[NSURLConnection alloc] initWithRequest:request1 delegate:self ], [[NSURLConnection alloc] initWithRequest:request2 delegate:self ], nil]; - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { fileData = [[NSMutableData alloc] init]; } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [fileData appendData:data]; } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"Unable to fetch data"); } ok, the download process works, but, the file size of jpg and mp3 are incorrect, the only correct thing is the total file size (jpg+mp3), please could you have a look on the code, what is missing? Another question is, I put the file in a NSMutableArray, my question is, how to check which index of array is the correct file type (jpg and mp3)? because I need to save them to the device folder.
