  • Cannot delete an image file that is shown in a listview

    - by Enrico
    Hello all, In my listview I show thumbnails of small images in a certain folder. I setup the listview as follows: var imageList = new ImageList(); foreach (var fileInfo in dir.GetFiles()) { try { var image = Image.FromFile(fileInfo.FullName); imageList.Images.Add(image); } catch { Console.WriteLine("error"); } } listView.View = View.LargeIcon; imageList.ImageSize = new Size(64, 64); listView.LargeImageList = imageList; for (int j = 0; j < imageList.Images.Count; j++) { var item = new ListViewItem {ImageIndex = j, Text = "blabla"}; listView.Items.Add(item); } The user can rightclick on an image in the listview to remove it. I remove it from the listview and then I want to delete this image from the folder. Now I get the error that the file is in use. Of course this is logical since the imagelist is using the file. I tried to first remove the image from the imagelist, but I keep on having the file lock. Can somebody tell me what I am doing wrong? Thanks!

  • jqModal dialog - only displaying once

    - by James Inman
    I've got a jqModal dialog with the following code: $(document).ready( function() { $('td.item.active').click( function(e) { $(this).append( '<div class="new">&nbsp;</div>' ); $("#jqModal").jqm({ modal:true, onHide: function(e) { e.w.hide(); // Hide window e.o.remove(); // Remove overlay } }); $('#jqModal').jqmShow(); $('input#add_session').click( function(e) { e.preventDefault(); $('#jqModal').hide(); $('.jqmOverlay').remove(); }); }); }); The HTML used is as follows: <div id="jqModal" class="jqmWindow"> <form action="" method="post"> <ul> <li> <input id="add_session" name="commit" type="submit" value="Add Session" /> <input type="button" name="close" value="Close" id="close" class="jqmClose" /> </li> </ul> </form> </div> When I first click a <td>, the dialog launches without a problem. On the second click (or subsequent), the new class is added to the <div>, but the dialog doesn't launch.

  • GWT forced height HTMLPanel

    - by Nils
    Hello, I'm developing a GWT project, and I encountered a problematic cross-browsering problem. When using firefox, there are problems with the display of all the pages. I found the reason why : In UIBinder, each of my pages are wrapped by a "g:HTMLPanel" : at start and at the end of the xml file, to wrap the content of all the pages When doing this, the generated code of the panel goes like this : div style="width: 100%; height: 100%; .... The problem is that "height : 100%". If I remove it with firebug, the display is perfect. So my goal is to programatically remove that generated 100% height.. But no way to do it ! I tried everything : setHeight, setSize, working on the Element itself with getElement().methods()... I tried to do things like style.clear(), everything that could have a chance to work.. But in the generated code that "height: 100%" will ALWAYS be there. If I set it's height to "50%" or "50px" it has no effect at all. I even tried to give it an ID, then with pure javascript to change it's style, but no solution either.. Note : I'm sure that I'm working on the right element : adding a styleName, for example, works well. Any idea ? Your help would be really appreciated, I have no clue of how to remove this bit of generated code, and I've been looking for hours already :(:(:(:( Best regards, Nils

  • LINQ-To-SQL and Mapping Table Deletions

    - by Jake
    I have a many-to-many relationship between two tables, let's say Friends and Foods. If a friend likes a food I stick a row into the FriendsFoods table, like this: ID Friend Food 1 'Tom' 'Pizza' FriendsFoods has a Primary Key 'ID', and two non-null foreign keys 'Friend' and 'Food' to the 'Friends' and 'Foods' tables, respectively. Now suppose I have a Friend tom .NET object corresponding to 'Tom', and Tom no longer likes pizza (what is wrong with him?) FriendsFoods ff = tblFriendsFoods.Where(x => x.Friend.Name == 'Tom' && x.Food.Name == 'Pizza').Single(); tom.FriendsFoods.Remove(ff); pizza.FriendsFoods.Remove(ff); If I try to SubmitChanges() on the DataContext, I get an exception because it attempts to insert a null into the Friend and Food columns in the FriendsFoods table. I'm sure I can put together some kind of convoluted logic to track changes to the FriendsFoods table, intercept SubmitChanges() calls, etc to try and get this to work the way I want, but is there a nice, clean way to remove a Many-To-Many relationship with LINQ-To-SQL?

  • how to reuse the area in a container when any component is removed from it?

    - by vybhav
    hi! i hav a panel and i m trying to remove labels from it which were added to it during run-time. but when labels are removed succesfully i m not able to use the space,left by that label,again to add any label to it. thanks in anticipation of the solution. here is the relevant code snippet: to add label to the panel: JLabel jl = new JLabel(); jl.setOpaque(true); jl.setIcon(new ImageIcon("D:/Project/router2.jpg")); jl.setBounds(x, y,jl.getPreferredSize().width,jl.getPreferredSize().height); for(Component c :lcomponent) { flag=true; Rectangle r4=c.getBounds(); int x1=(int) r4.getX(); int y1=(int) r4.getY(); Rectangle r5 = new Rectangle(new Point(x1-60, y1-60),new Dimension(170,170)); if(r5.contains(p)){ //To ensure that two labels do not overlap or are too close flag = false; // to each other break; }} if(flag) { p2.add(jl); //p2 is a panel Component c2 = p2.getComponentAt(x,y); p2.repaint(); lcomponent.add(c2); //lcomponent is an ArrayList<Component> to store all the labels added to the panel } 2.to remove the label: p2.remove(); p2.repaint();

  • Hibernate triggering constraint violations using orphanRemoval

    - by ptomli
    I'm having trouble with a JPA/Hibernate (3.5.3) setup, where I have an entity, an "Account" class, which has a list of child entities, "Contact" instances. I'm trying to be able to add/remove instances of Contact into a List<Contact> property of Account. Adding a new instance into the set and calling saveOrUpdate(account) persists everything lovely. If I then choose to remove the contact from the list and again call saveOrUpdate, the SQL Hibernate seems to produce involves setting the account_id column to null, which violates a database constraint. What am I doing wrong? The code below is clearly a simplified abstract but I think it covers the problem as I'm seeing the same results in different code, which really is about this simple. SQL: CREATE TABLE account ( INT account_id ); CREATE TABLE contact ( INT contact_id, INT account_id REFERENCES account (account_id) ); Java: @Entity class Account { @Id @Column public Long id; @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true) @JoinColumn(name = "account_id") public List<Contact> contacts; } @Entity class Contact { @Id @Column public Long id; @ManyToOne(optional = false) @JoinColumn(name = "account_id", nullable = false) public Account account; } Account account = new Account(); Contact contact = new Contact(); account.contacts.add(contact); saveOrUpdate(account); // some time later, like another servlet request.... account.contacts.remove(contact); saveOrUpdate(account); Result: UPDATE contact SET account_id = null WHERE contact_id = ? Edit #1: It might be that this is actually a bug http://opensource.atlassian.com/projects/hibernate/browse/HHH-5091

  • Detecting a Dispose() from an exception inside using block

    - by Augusto Radtke
    I have the following code in my application: using (var database = new Database()) { var poll = // Some database query code. foreach (Question question in poll.Questions) { foreach (Answer answer in question.Answers) { database.Remove(answer); } // This is a sample line that simulate an error. throw new Exception("deu pau"); database.Remove(question); } database.Remove(poll); } This code triggers the Database class Dispose() method as usual, and this method automatically commits the transaction to the database, but this leaves my database in an inconsistent state as the answers are erased but the question and the poll are not. There is any way that I can detect in the Dispose() method that it being called because of an exception instead of regular end of the closing block, so I can automate the rollback? I don´t want to manually add a try ... catch block, my objective is to use the using block as a logical safe transaction manager, so it commits to the database if the execution was clean or rollbacks if any exception occured. Do you have some thoughts on that?

  • ASP.NET SQLMembership Provider not logging in

    - by cfdev9
    My web app uses the sql memebership provider. Running it locally all is well, deploying to a dev server it works fine too in firefox, but in IE8 something unexpected is happening. Once a user logs in they're supposed to be redirected to home.aspx. What's happening when I attempt to login is it appears to accept the login credentials but then doesn't redirect to home.aspx. Instead it just redirects me to the login page as though I had attempted to access home.aspx directly without being logged in. The url parameter ReturnUrl is appended, Login.aspx?ReturnUrl=%2fhome.aspx Why is this only happening with IE8? My local PC is IIS7 but the server is IIS6. Using the same web.config Full code behind public partial class Login : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { Session.Abandon(); FormsAuthentication.SignOut(); } } protected void btnSubmit_Click(object sender, EventArgs e) { if (Membership.ValidateUser(tbUsername.Text, tbPassword.Text)) { if (Request.QueryString["ReturnUrl"] != null) { FormsAuthentication.RedirectFromLoginPage(tbUsername.Text, false); } else { FormsAuthentication.SetAuthCookie(tbUsername.Text, false); Response.Redirect("~/Home.aspx"); } } } } Full web.config

  • How do I find the object with the oldest updated_at column in RJS?

    - by user284194
    Hello, I'm trying to remove the object with the oldest updated_at value when the rjs is executed. page.insert_html :top, :messages, :partial => @message page[@message].visual_effect :grow page[:message_form].reset Message.old_messages.each do |m| page.remove(m.id) end page.delay(1) do page.select('.message').last.visual_effect :fade end I'm using .last in there right now, but I have a periodically_call_remote in the view that continually updates and runs the rjs above. The line: page.select('.message').last.visual_effect :fade seems to only execute the first time because after the message that is "last" fades away there's nothing recognized as "last" anymore so I figure instead of calling .last I could find the object that has the oldest updated_at time stamp and just remove that instead. I'm thinking that I probably cannot do this using page.select since it only calls on css elements. And therefore I probably don't have access to the updated_at values in the Message model. Does anyone have a suggestion on how to accomplish removing the oldest message with rjs? The messages are already automatically removed in the model as new messages are created. But I want them to fade automatically when the RJS refreshes the element.

  • jQuery validate and tabs

    - by ntan
    Hi i am using jQuery validate for my form validation. The form is inside tabs.When i get an error i add an icon to the tab that error exist to be visual by the user So far so good. My problem is that after correct the error i can not remove the error in tab icon. I was assuming that validator is accessible via success but its not Assuming that the first tab (tab0) has 3 field for validation (field1,field2,field3) Here is the full code $("form#Form1") .validate({ invalidHandler: function(form, validator) { //TAB 0 if (validator.errorMap.field1 != "" && validator.errorMap.field2 != "" && validator.errorMap.field3 != "") { if ($("#tabs>ul>li").eq(0).find("img").length == 0) { $("#tabs>ul>li").eq(0).prepend("<img src=\"error.gif\">"); } } }, errorClass: "errorField", errorElement: "p", errorPlacement: function(error, element) { var parent = element.parent(); parent.addClass("error"); error.prependTo( parent ); }, //validator in not accessible via success //so my code its not working success: function(element,validator) { var parent = element.parent(); parent.removeClass("error"); $(parent).children("p.errorField").remove(); //TAB 0 if (validator.errorMap.field1 == "" && validator.errorMap.field2 == "" && validator.errorMap.field2 == "") { if ($("#tabs>ul>li").eq(0).find("img").length == 0) { $("#tabs>ul>li").eq(0).find("img").remove(); } } }, rules: { field1: { required: true }, field2: { required: true }, field3: { required: true } } }); Any suggestion is welcome.

  • Deleting objects with FK constraints in Spring/Hibernate

    - by maxdj
    This seems like such a simple scenario to me, yet I cannot for the life of my find a solution online or in print. I have several objects like so (trimmed down): @Entity public class Group extends BaseObject implements Identifiable<Long> { private Long id; private String name; private Set<HiringManager> managers = new HashSet<HiringManager>(); private List<JobOpening> jobs; @ManyToMany(fetch=FetchType.EAGER) @JoinTable( name="group_hiringManager", joinColumns=@JoinColumn(name="group_id"), inverseJoinColumns=@JoinColumn(name="hiringManager_id") ) public Set<HiringManager> getManagers() { return managers; } @OneToMany(mappedBy="group", fetch=FetchType.EAGER) public List<JobOpening> getJobs() { return jobs; } } @Entity public class JobOpening extends BaseObject implements Identifiable<Long> { private Long id; private String name; private Group group; @ManyToOne @JoinColumn(name="group_id", updatable=false, nullable=true) public Group getGroup() { return group; } } @Entity public class HiringManager extends User { @ManyToMany(mappedBy="managers", fetch=FetchType.EAGER) public Set<Group> getGroups() { return groups; } } Say I want to delete a Group object. Now there are dependencies on it in the JobOpening table and in the group_hiringManager table, which cause the delete function to fail. I don't want to cascade the delete, because the managers have other groups, and the jobopenings can be groupless. I have tried overriding the remove() function of my GroupManager to remove the dependencies, but it seems like no matter what I do they persist, and the delete fails! What is the right way to remove this object?

  • Problem with Railscast #197 - Nested Model Form Part 2

    - by sscirrus
    I'm trying to implement Ryan's Railscast #197 in a system with Questions, Answers, and (multiple choice) Options. http://railscasts.com/episodes/197-nested-model-form-part-2. I have successfully implemented the nesting among these forms/partials. The simpler 'check box' way to delete records works properly. The problem occurs when I try to add/delete records. I have copied the code exactly as it appears in his Railscast: #new.html.erb <%= javascript_include_tag :defaults, :cache => true %> <% f.fields_for :in_options do |builder| %> <%= render "option_fields", :f => builder %> <% end %> #_option_fields.html.erb partial <%= f.hidden_field :_destroy %> <%= link_to_function "remove", "remove_fields(this)" %> #application_helper.rb (exact same as #197) def link_to_remove_fields(name, f) f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)") end def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")) end #application.js (exact same as #197. I have an Event.addbehavior below this code.) function remove_fields(link) { $(link).previous("input[type=hidden]").value = "1"; $(link).up(".fields").hide(); } function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); } 2 problems: When I click on the 'remove' link it doesn't remove - it just shifts the page up or down. When I include link_to_add_fields "Add Answer", f, :answers, I get undefined method `klass' for nil:NilClass. Thanks everyone.

  • IE bug with TD's tables and whitespace?

    - by mark smith
    Hi there, I have a page that is using tables, in FF etc it works perfect, but in IE7 it causes issues, its basically where the four corners have a td and and img (its a rounded corner form) .. if i remove the whitespace from the document it fixes the issue.. What actually happens is that it messes up the tables.. it puts a thin white line between the upper tr that holds the 2 corners and the next tr I need to remove the the whitespace between the img and the TD, is there a better work around, as i have lots and not only that if i reformat the document the problem returns.. here is a simple example.. <table width="100%" height="418" border="0" cellpadding="0" cellspacing="0" bgcolor="#F04A23" style="margin: 0px; padding: 0px"> <tr> <td width="12" align="left" valign="top"> <img src="content/images/corner_left.gif" width="12" height="12" /> </td> as you can see there is white space between img and td... and i remove it so it looks like this <img src="content/images/corner_left.gif" width="12" height="12" /></td> the problem is gone, (notice the td and image are right next to each other) Any ideas, i tried setting all sorts of css, padding 0px, margins 0px etc ... Any ideas really appreciated

(simple replace all - "www." with "") Delete any sub-domains (delete the actual row completely, not just the subdomain from the url) Remove anything after the domain extension (i.e. website.com/blah/blahbah/ becomes just website.com (simple replace all - "/*" with "", then replace all "/" with "") So what I'm left with is just a spreadsheet of clean domains like "website.com". I think I've got 1, 2 and 4 sorted (as above), but I'm really struggling with 3. Any ideas? Can I do this with regexp / vba, and actually delete the row completely? Sample data: http://www.scholastic.com/kids/stacks/games/ http://imgworld.teamworkonline.com/ http://topfreegraphics.com/ http://www.workcircle.co.uk/ http://www.healthycanadians.gc.ca/index-eng.php http://gsociology.icaap.org/methods/soft.html Post 1, 2 and 4 would leave me with: scholastic.com imgworld.teamworkonline.com topfreegraphics.com workcircle.co.uk healthycanadians.gc.ca gsociology.icaap.org It's those pesky sub-domains I need to just delete completely, just delete the row. I've realised I can't just search for 2 x ".", because obviously plenty of domain extensions (i.e .co.uk) include that. Any help appreciated.

  • Problem accessing variable in a nested form partial

    - by brad
    I have a nested form in a rails view that is called like this <% f.fields_for :invoice_item_numbers do |item_no_form| %> <%= render 'invoice_item_number', :f => item_no_form %> <% end %> and the partial (_invoice_item_number.html.erb) looks like this <div class='invoice_item_numbers'> <% if f.object.new_record? %> <li><%= f.label :item_number %><%= f.text_field :item_number %> <%= link_to_function "remove", "$(this).parent().remove()", :class => 'remove_link' %></li> <% else %> <li class="inline"><%= f.label :item_number %><%= f.text_field :item_number %> </li><li class="inline"><%= f.label :description %><%= invoice_item_number.description %></li><li><%= f.label :amount %><%= f.text_field :amount %> <%= f.check_box '_destroy', :class => 'remove_checkbox' %> <%= f.label '_destroy', 'remove', :class => 'remove_label' %></li> <% end %> </div> This fails with the error message undefined method `description' for nil:NilClass Why does invoice_item_number return a nil object in this partial? It is obviously being defined somehow because if I change it to something else (e.g. item_number.description then the error message becomes undefined local variable or methoditem_number' for #instead. The invoice_item_number object that is being displayed by this partial is being used perfectly well by the form helpers as<%= f.text_field :item_number %and<% f.text_field :amount %both work perfectly well. I have tried a number of solutions such as using@invoice_item_number` and explicitly defining an object in the render method but these have not worked. Presumably there is a very simple answer to this.

  • jquery clone only once

    - by tsiger
    I have a series of divs like this: <div id="available-posts"> <div class="post" id="unique_id"> <a href="#" class="addme">Add</a> Some text </div> <div class="post" id="unique_id"> <a href="#" class="addme">Add</a> Some text </div> </div> The unique_id is a different number for each of the divs. Now i have a new empty div like this <div class="related-posts"></div> And i clone items in there. The thing is that i want to check if an item is already cloned. If it is i want to stop it from being cloned again. This is how i clone items: // clone it $('.addme').live('click', function() { $(this).parents('div.thepost').clone().fadeIn('normal').appendTo('#related-posts').find('a.addme').html('Remove').removeClass('addme').addClass('removeme'); return false; }); // remove it $('.removeme').live('click', function() { $(this).parents('div.thepost').fadeOut('normal', function() {$(this).remove(); }); return false; }); In other words i want the cloned list to contain only unique items. Not for example 2 clones of the same post. *edit: i am using live coz the first list (available posts) is populated through an AJAX call.

  • backbone.js removing template from DOM upon success

    - by timpone
    I'm writing a simple message board app to learn backbone. It's going ok (a lot of the use of this isn't making sense) but am a little stuck in terms of how I would remove a form / html from the dom. I have included most of the code but you can see about 4 lines up from the bottom, the part that isn't working. How would I remove this from the DOM? thx in advance var MbForm=Backbone.View.extend({ events: { 'click button.add-new-post': 'savePost' }, el: $('#detail'), template:_.template($('#post-add-edit-tmpl').html()), render: function(){ var compiled_template = this.template(); this.$el.html(compiled_template); return this; }, savePost: function(e){ //var self=this; //console.log("I want you to say Hello!"); data={ header: $('#post_header').val(), detail: $('#post_detail').val(), forum_id: $('#forum_id').val(), post_id: $('#post_id').val(), parent_id: $('#parent_id').val() }; this.model.save(data, { success: function(){ alert('this saved'); //$(this.el).html('this is what i want'); this.$el.remove();// <- this is the part that isn't working /* none of these worked - error Uncaught TypeError: Cannot call method 'unbind' of undefined this.$el.unbind(); this.$el.empty(); this.el.unbind(); this.el.empty(); */ //this.unbind(); //self.append('this is appended'); } });

  • stripping default.aspx and //www from the url

    - by b0x0rz
    the code to strip /Default.aspx and //www is not working (as expected): protected void Application_BeginRequest(object sender, EventArgs e) { HttpContext context = HttpContext.Current; string url = context.Request.RawUrl.ToString(); bool doRedirect = false; // remove > default.aspx if (url.EndsWith("/default.aspx", StringComparison.OrdinalIgnoreCase)) { url = url.Substring(0, url.Length - 12); doRedirect = true; } // remove > www if (url.Contains("//www")) { url = url.Replace("//www", "//"); doRedirect = true; } // redirect if necessary if (doRedirect) { context.Response.Redirect(url); } } it works usually, but when submitting a form (sign in for example) the code above INTERCEPTS the request and then does a redirect to the same page. example: try to arrive at page: ~/SignIn/Default.aspx the requests gets intercepted and fixed to: ~/SignIn/ fill the form, click sign in the current page url goes from: ~/SignIn/ to ~/SignIn/Default.aspx and gets fixed again, thus voiding the processing of the method SignIn (which would have redirected the browser to /SignIn/Success/) and the page is reloaded as ~/SignIn/ and no sign in was done. please help. not sure what / how to fix here. the main REQUIREMENT here is: remove /Default.aspx and //www from url's thnx

  • git-svn cannot create a branch to follow SVN branching

    - by Serhiy Yakovyn
    Hello everybody, I'm struggling with the following issue. When I continue fetching revisions from SVN with git svn fetch I'm getting the following error (removed https to be able to post question): *Found possible branch point: somecompany.com/product/trunk = somecompany.com/product/branches/deep/branches/product-001, 72666 Found branch parent: (refs/remotes/deep/branches/product-001) b685b7b92813885fdf 6b8e2663daf884bf504b14 Following parent with do_switch Successfully followed parent error: 'refs/remotes/deep' exists; cannot create 'refs/remotes/deep/branches/product-001' fatal: Cannot lock the ref 'refs/remotes/deep/branches/product-001'. update-ref -m r72667 refs/remotes/deep/branches/product-001 df51920e8f0a53f26507 c2679eb6a9dbad91e0d6: command returned error: 128* This happened because I was fetching revisions using the default filter for SVN branches: [svn-remote "svn"] url = https://somecompany.com/someproduct fetch = trunk:refs/remotes/trunk branches = branches/*:refs/remotes/* tags = tags/*:refs/remotes/tags/* Now, I have the line below added, but it's too late: branches = branches/deep/branches/*:refs/remotes/deep/branches/* I have tried to fix this by using git reset to remove all the commits. Actually I can see from the error message that git is trying right thing, but cannot because of the branch remotes/deep being existing. I have tried to search for 2 possible solutions: 1. Remove that branch (remotes/deep), but as it is tracked by git as a remote, I was not able to find any solution for that. 2. Remove the whole history related to that branch. No success too :( Does anybody know how to deal with my issue? Thank you in advance, Serhiy Y

  • R - removing rows and replacing values using conditions from multiple columns

    - by lecodesportif
    I want to filter out all values of var3 < 5 while keeping at least one occurrence of each value of var1. > foo <- data.frame(var1= c(1, 1, 2, 3, 3, 4, 4, 5), var2=c(9, 5, 13, 9, 12, 11, 13, 9), var3=c(6, 8, 3, 6, 4, 7, 2, 9)) > foo var1 var2 var3 1 1 9 6 2 1 5 8 3 2 13 3 4 3 9 6 5 3 12 4 6 4 11 7 7 4 13 2 8 5 9 9 subset(foo, (foo$var3>=5)) would remove row 3, 5 and 7 and I would have lost var1==2. I want to remove the row if there is another value of var1 that fulfills the condition foo$var3 = 5. See row 5. I want to keep the row, assiging NA to var2 and var3 if all occurrences of a value var1 do not fulfill the condition foo$var3 = 5. This is the result I expect: var1 var2 var3 1 1 9 6 2 1 5 8 3 2 NA NA 4 3 9 6 6 4 11 7 8 5 9 9 This is the closest I got: > foo$var3[ foo$var3 < 5 ] = NA > foo$var2[ is.na(foo$var3) ] = NA > foo var1 var2 var3 1 1 9 6 2 1 5 8 3 2 NA NA 4 3 9 6 5 3 NA NA 6 4 11 7 7 4 NA NA 8 5 9 9 So I guess I just need to know how to conditionally remove the row.
