  • Using nawk, how to print the first names for all those in the 916 area code? [closed]

  • How to jump back to the first character in *nix command line?

    - by clami219
    When writing a long command in the *nix command line and having to go back to the first character, in order to add something at the beginning (for instance a nohup, when you realize the process will be a long one, or a sudo, when you realize you need root permissions) it can take a long time for the cursor to make its way back to the first character... Is there a short cut that allows you to jump straight there? I'm using a mac, so Home is not an option

  • How to find first non-repetitive character from a string?

    - by masato-san
    I've spent half day trying to figure out this and finally I got working solution. However, I feel like this can be done in simpler way. I think this code is not really readable. Problem: Find first non-repetitive character from a string. $string = "abbcabz" In this case, the function should output "c". The reason I use concatenation instead of $input[index_to_remove] = '' in order to remove character from a given string is because if I do that, it actually just leave empty cell so that my return value $input[0] does not not return the character I want to return. For instance, $str = "abc"; $str[0] = ''; echo $str; This will output "bc" But actually if I test, var_dump($str); it will give me: string(3) "bc" Here is my intention: Given: input while first char exists in substring of input { get index_to_remove input = chars left of index_to_remove . chars right of index_to_remove if dupe of first char is not found from substring remove first char from input } return first char of input Code: function find_first_non_repetitive2($input) { while(strpos(substr($input, 1), $input[0]) !== false) { $index_to_remove = strpos(substr($input,1), $input[0]) + 1; $input = substr($input, 0, $index_to_remove) . substr($input, $index_to_remove + 1); if(strpos(substr($input, 1), $input[0]) == false) { $input = substr($input, 1); } } return $input[0]; }

  • How can I create a JTable where the first column is always in the JScrollPane viewport?

    - by voodoogiant
    What's the best way to set up a table in a JScrollPane such that the first column is always on the screen in the same position regardless of horizontal scrolling and overlaps columns that pass underneath? When the scrollbar is at the farthest left, the columns look normal, but as the user scrolls to the right, the secondary columns (2 and on) move underneath the first until the last column appears on the far right of the viewport? I found a sample taken from Eckstein's "Java Swing" book that sort of does this, but it doesn't allow resizing of the first column. I was thinking of some scheme where one JPanel held a horizontal struct and a table holding the secondary columns and another JPanel which floated over them (fixed regardless of scrolling). The struct would be to keep the viewport range constant as the first column floated around. Ideally I could do it with two tables using the same model, but I'm not sure if the whole idea is a naive solution.

  • Apache keeps resetting while testing on localhost...

  • How do I decrease first load time in ASP.net MVC 2?

    - by Bill
    I have an ASP.net MVC 2 application that runs well locally. However when I move the files to my production server, I get a first time lag of about 30 seconds, I assume this is a first compile. After that the application works fine. Then after about 20-30 minutes of non use, the applications takes another 30 seconds or so to load. I did try to precompile the code, but there is still a lag during the first load. Are there any trick to getting the application to work faster on the first load? I am using ASP.net 3.5, IIS 6 , visual studio 2010, MVC 2. Thanks

  • How do you make an added row from QueryAddRow() the first row of the result from a query?

    - by JS
    I am outputting a query but need to specify the first row of the result. I am adding the row with QueryAddRow() and setting the values with QuerySetCell(). I can create the row fine, I can add the content to that row fine. If I leave the argument for the row number off of QuerySetCell() then it all works great as the last result of the query when output. However, I need it to be first row of the query but when I try to set the row attribute with the QuerySetCell it just overwrites the first returned row from my query (i.e. my QueryAddRow() replaces the first record from my query). What I currently have is setting a variable from recordCount and arranging the output but there has to be a really simple way to do this that I am just not getting. This code sets the row value to 1 but overwrites the first returned row from the query. <cfquery name="qxLookup" datasource="#application.datasource#"> SELECT xID, xName, execution FROM table </cfquery> <cfset QueryAddRow(qxLookup)/> <cfset QuerySetCell(qxLookup, "xID","0",1)/> <cfset QuerySetCell(qxLookup, "xName","Delete",1)/> <cfset QuerySetCell(qxLookup, "execution", "Select this to delete",1)/> <cfoutput query="qxLookup"> <tr> <td> <a href="##" onclick="javascript:ColdFusion.navigate('xSelect/x.cfm?xNameVar=#url.xNameVar#&xID=#qxLookup.xID#&xName=#URLEncodedFormat(qxLookup.xName)#', '#xNameVar#');ColdFusion.Window.hide('#url.window#')">#qxLookup.xName#</a> </td> <td>#qxLookup.execution#</td> </tr> </cfoutput> </table> Thanks for any help.

  • How to get jQuery to find the first list-item, rather than all list-items?

    - by ricebowl
    I'm trying to implement a basic jQuery infinite carousel. As much for the learning process as for anything else (as a rule I'm not a fan of re-inventing wheels, but...I have to learn somehow, might as well start with the basics). I've managed to get the list to animate left happily enough, but I'm stuck when it comes to selecting the first element of the list. I've tried to use: $('ul#services > li:first'); $('ul#services > li:first-child'); $('ul#services > li').eq([0]); (xhtml below), In each case a console.log(first) (the var name used) returns all of the list-items. Am I doing something blatantly, and obviously, wrong? The eventual plan is to clone the first li, append it to the parent ul, remove the li from the list and allow the list to scroll infinitely. It's just a list of services rather than links so I'm not -at the moment- planning to have scroll or left/right functionality. Current xhtml: <div class="wrapper"> <ul id="services"> <!-- closing the `</li>` tags on the following line is to remove whitespace in the horizontal list, doesn't seem to make a difference to the jQuery from my own testing. --> <li>one</li ><li>two</li ><li>three</li ><li>four</li ><li>five</li ><li>six</li ><li>seven</li ><li>eight</li ><li>nine</li ><li>ten</li> </ul> </div>

  • PHP export to text file - Only saving first line.

    - by wertz8090
    I'm trying to export some extracted $_POST information into a text file, however my code is only capturing the first variable and ignoring the rest. I'm saving the information to the text file in this manner: $values = "First Name: $fName\r\n"; $values .= "Last Name: $lName\r\n"; $values .= "Address: $address\r\n"; etc. This is the code I use to write to the text file: $fp = @fopen("person.data", "w") or die("Couldn't open person.data for writing!"); $numBytes = @fwrite($fp, $values) or die("Couldn't write values to file!"); @fclose($fp); Any ideas on why it would only save the first $values ($fName) variable but not the rest of them? It actually saves the first part of the $values string for all of them (so I see Last Name:, Address:, etc. on separate lines in the text file) but the called variables $lName and $address do not appear.

  • How to add values accordingly of the first indices of a dictionary of tuples of a list of strings? Python 3x

    - by TheStruggler
    I'm stuck on how to formulate this problem properly and the following is: What if we had the following values: {('A','B','C','D'):3, ('A','C','B','D'):2, ('B','D','C','A'):4, ('D','C','B','A'):3, ('C','B','A','D'):1, ('C','D','A','B'):1} When we sum up the first place values: [5,4,2,3] (5 people picked for A first, 4 people picked for B first, and so on like A = 5, B = 4, C = 2, D = 3) The maximum values for any alphabet is 5, which isn't a majority (5/14 is less than half), where 14 is the sum of total values. So we remove the alphabet with the fewest first place picks. Which in this case is C. I want to return a dictionary where {'A':5, 'B':4, 'C':2, 'D':3} without importing anything. This is my work: def popular(letter): '''(dict of {tuple of (str, str, str, str): int}) -> dict of {str:int} ''' my_dictionary = {} counter = 0 for (alphabet, picks) in letter.items(): if (alphabet[0]): my_dictionary[alphabet[0]] = picks else: my_dictionary[alphabet[0]] = counter return my_dictionary This returns duplicate of keys which I cannot get rid of. Thanks.

  • Can I have an android activity run only on the first time an application is opened?

    - by The Trav
    OK, so I'm playing around with an android app. The 90% use case is that users want to go straight to the primary list screen to find what they're looking for. That's what I want as my default screen. The first time a user loads the app however, some configuration is required before their list screen is of any value to them. So my question, is how I can go about displaying the configuration activity the first time the app is opened up, and then the list screen for future openings. I also want to put a demo button on the configuration screen, so I suppose more than just detecting that it's the first time, I specifically want to detect whether the user has performed certain configurations within the first screen.

  • Parse an XML file

    - by karan@dotnet
    The following code shows a simple method of parsing through an XML file/string. We can get the parent name, child name, attributes etc from the XML. The namespace System.Xml would be the only additional namespace that we would be using. string myXMl = "<Employees>" + "<Employee ID='1' Name='John Mayer'" + "Address='12th Street'" + "City='New York' Zip='10004'>" + "</Employee>" + "</Employees>"; XmlDocument xDoc = new XmlDocument();xDoc.LoadXml(myXMl);XmlNodeList xNodeList = xDoc.SelectNodes("Employees/child::node()");foreach (XmlNode xNode in xNodeList){ if (xNode.Name == "Employee") { string ID = xNode.Attributes["ID"].Value; //Outputs: 1 string Name = xNode.Attributes["Name"].Value;//Outputs: John Mayer string Address = xNode.Attributes["Address"].Value;//Outputs: 12th Street string City = xNode.Attributes["City"].Value;//Outputs: New York string Zip = xNode.Attributes["Zip"].Value; //Outputs: 10004 }} Lets look at another XML: string myXMl = "<root>" + "<parent1>..some data</parent1>" + "<parent2>" + "<Child1 id='1' name='Adam'>data1</Child1>" + "<Child2 id='2' name='Stanley'>data2</Child2>" + "</parent2>" + "</root>"; XmlDocument xDoc = new XmlDocument();xDoc.LoadXml(myXMl);XmlNodeList xNodeList = xDoc.SelectNodes("root/child::node()"); //Traverse the entire XML nodes.foreach (XmlNode xNode in xNodeList) { //Looks for any particular nodes if (xNode.Name == "parent1") { //some traversing.... } if (xNode.Name == "parent2") { //If the parent node has child nodes then //traverse the child nodes foreach (XmlNode xNode1 in xNode.ChildNodes) { string childNodeName = xNode1.Name; //Ouputs: Child1 string childNodeData = xNode1.InnerText; //Outputs: data1 //Loop through each attribute of the child nodes foreach (XmlAttribute xAtt in xNode1.Attributes) { string attrName = xAtt.Name; //Outputs: id string attrValue = xAtt.Value; //Outputs: 1 } } }}

  • Where do I define a group policy that will set a users desktop background color to green the first time they log in?

    - by Tyler
    Servers: W2k8 R2 x64 Desktops: Win7 Pro x64 Our current group policy uses a custom ADM file to define certain properties of the desktop (Background Image (centered), Background Color is green (00 74 00)). This policy works for us, but the down-side is that policies defined in our custom ADM are only applied after a GPUpdate /Force is applied. We would like these desktop theme settings to be applied the first time the user logs onto the computer. I've been working on a new policy that forces the computer to wait for the network when the user logs on to handle folder redirection. The reason for writing the new policy was to resolve the issue that a user needs to run GPupdate /Force the first time they log in, so it doesn't make sense for me to implement the new policy if there is still something that requires GPUpdate /Force to get the user in the state that we want them. I've moved the setting for background image out into Admin Templates- Desktop- Desktop- "Desktop Wallpaper" so this is now being set properly when the user first logs in. Now I'm left with a black background until I force a group policy update. I have tried to play around with setting a default "Theme" and had limited success; this was not reliable enough to call a solution. I suppose I could set the background color with a script? Any thoughts? It feels like I'm missing something obvious, or that this should be much easier than it is.

The issue i am facing is if i have a filter on parent child dimension then drill through table does not show filtered data instead it shows all the data for that dimension. Here is an example. <Dimension type="StandardDimension" name="page_type_d" caption="Page Type"> <Hierarchy name="page_type_h" hasAll="true" allMemberName="all_page_types" allMemberCaption="All Page Types" primaryKey="id"> <Table name="npg_page_type_view" alias="pt"> </Table> <Level name="Page Type" column="id" nameColumn="display_name" parentColumn="parent_id" nullParentValue="0" type="Integer" uniqueMembers="true" levelType="Regular" hideMemberIf="Never" caption="Page Type"> <Closure parentColumn="parent_id" childColumn="page_type_id"> <Table name="dim_page_types_closure"> </Table> </Closure> </Level> </Hierarchy> Now suppose i have 4 rows in npg_page_type_view table id display_name parent_id 19 HTML 100 20 PDF 100 21 XML 0 100 Total 0 Now suppose in my fact table i have following records id count 19 2 20 3 21 1 Following is my analysis view. Total (HTML and PDF) - 5 HTML - 2 PDF - 3 XML - 1 Now if i add filter(say Total) on this analysis view using OLAP cube. Then my analysis view shows the following. Total (HTML and PDF) - 5 Upto this point everything works fine. Now if i click on 5 (to view drill through table) It shows me data against all page type i.e. HTML, PDF, XML but as per filter it should show only HTML and PDF. Is it an exciting issue or am i doing something wrong here? Please help me.

  • How do you deserialize a collection with child collections?

    - by Stuart Helwig
    I have a collection of custom entity objects one property of which is an ArrayList of byte arrays. The custom entity is serializable and the collection property is marked with the following attributes: [XmlArray("Images"), XmlArrayItem("Image",typeof(byte[]))] So I serialize a collection of these custom entities and pass them to a web service, as a string. The web service receives the string and byte array in tact, The following code then attempts to deserialize the collection - back into custom entities for processing... XmlSerializer ser = new XmlSerializer(typeof(List<myCustomEntity>)); StringReader reader = new StringReader(xmlStringPassedToWS); List<myCustomEntity> entities = (List<myCustomEntity>)ser.Deserialize(reader); foreach (myCustomEntity e in entities) { // ...do some stuff... foreach (myChildCollection c in entities.ChildCollection { // .. do some more stuff.... } } I've checked the XML resulting from the initial serialization and it does contain byte array - the child collection, as does the StringReader built above. After the deserialization process, the resulting collection of custom entites is fine, except that each object in the collection does not contain any items in its child collection. (i.e. it doesn't get to "...do some more stuff..." above. Can someone please explain what I am doing wrong? Is it possible to serialize ArrayLists within a generic collection of custom entities?

  • WPF: Setting DataContext of a UserControl with Binding not working in XAML

    - by Grant Crofton
    Hi, I'm trying to get my first WPF app working using MVVM, and I've hit a little binding problem. The setup is that I have a view & viewModel which holds User details (the parent), and to try and keep things simple I've put a section of that view into a separate view & viewModel (the child). The child view is defined as a UserControl. The issue I'm having is how to set the DataContext of the child view (the UserControl). My parent ViewModel has a property which exposes the child ViewModel, like so: class ParentViewModel: INotifyPropertyChanged { public ChildViewModel childViewModel { get; set; } //... } In the XAML for my parent view (which has it's DataContext set to the ParentViewModel), I try to set the DataContext of the child view as follows: <views:ChildView x:Name="ChildView" DataContext="{Binding childViewModel}"/> However, this doesn't work. The DataContext of the child view is set to the same DataContext as the parent view (i.e. the ParentViewModel), as if I wasn't setting it at all. I also tried setting the DataContext in the child view itself, which also doesn't work: <UserControl x:Class="DietRecorder.Client.View.ChildView" DataContext="childViewModel" I have found a couple of ways around this. In the child view, I can bind everything by including the ChildViewModel in the path: <SomeControl Visibility="{Binding Path=childViewModel.IsVisible}"> but I don't want the child view to have this level of awareness of the hierarchy. Setting the DataContext in code also works - however, I have to do this after showing the parent view, otherwise the DataContext just gets overwritten when I call Show(): parentView.Show(); parentView.ChildView.DataContext = parentViewModel.childViewModel; This code also makes me feel uneasy, what with the LOD violation and all. It's just the DataContext that seems to be the problem - I can bind other things in the child, for example I tried binding the FontSize to an int property just to test it: <views:ChildView x:Name="ChildView" FontSize="{Binding Path=someVal}"/> And that works fine. But I'm sure binding the DataContext should work - I've seen similar examples of this kind of thing. Have I missed something obvious here? Is there a reason this won't work? Is there a spelling mistake somewhere? (I renamed things for your benefit so you won't be able to help me there anyway). Any thoughts welcome. Thanks, Grant

  • ASP.NET MVC 2: Updating a Linq-To-Sql Entity with an EntitySet

    - by Simon
    I have a Linq to Sql Entity which has an EntitySet. In my View I display the Entity with it's properties plus an editable list for the child entites. The user can dynamically add and delete those child entities. The DefaultModelBinder works fine so far, it correctly binds the child entites. Now my problem is that I just can't get Linq To Sql to delete the deleted child entities, it will happily add new ones but not delete the deleted ones. I have enabled cascade deleting in the foreign key relationship, and the Linq To Sql designer added the "DeleteOnNull=true" attribute to the foreign key relationships. If I manually delete a child entity like this: myObject.Childs.Remove(child); context.SubmitChanges(); This will delete the child record from the DB. But I can't get it to work for a model binded object. I tried the following: // this does nothing public ActionResult Update(int id, MyObject obj) // obj now has 4 child entities { var obj2 = _repository.GetObj(id); // obj2 has 6 child entities if(TryUpdateModel(obj2)) //it sucessfully updates obj2 and its childs { _repository.SubmitChanges(); // nothing happens, records stay in DB } else ..... return RedirectToAction("List"); } and this throws an InvalidOperationException, I have a german OS so I'm not exactly sure what the error message is in english, but it says something along the lines of that the entity needs a Version (Timestamp row?) or no update check policies. I have set UpdateCheck="Never" to every column except the primary key column. public ActionResult Update(MyObject obj) { _repository.MyObjectTable.Attach(obj, true); _repository.SubmitChanges(); // never gets here, exception at attach } I've read alot about similar "problems" with Linq To Sql, but it seems most of those "problems" are actually by design. So am I right in my assumption that this doesn't work like I expect it to work? Do I really have to manually iterate through the child entities and delete, update and insert them manually? For such a simple object this may work, but I plan to create more complex objects with nested EntitySets and so on. This is just a test to see what works and what not. So far I'm disappointed with Linq To Sql (maybe I just don't get it). Would be the Entity Framework or NHibernate a better choice for this scenario? Or would I run into the same problem?

  • One-to-one Mapping issue with NHibernate/Fluent: Foreign Key not updateing

    - by Trevor
    Summary: Parent and Child class. One to one relationship between the Parent and Child. Parent has a FK property which references the primary key of the Child. Code as follows: public class NHTestParent { public virtual Guid NHTestParentId { get; set; } public virtual Guid ChildId { get { return ChildRef.NHTestChildId; } set { } } public virtual string ParentName { get; set; } protected NHTestChild _childRef; public virtual NHTestChild ChildRef { get { if (_childRef == null) _childRef = new NHTestChild(); return _childRef; } set { _childRef = value; } } } public class NHTestChild { public virtual Guid NHTestChildId { get; set; } public virtual string ChildName { get; set; } } With the following Fluent mappings: Parent Mapping Id(x => x.NHTestParentId); Map(x => x.ParentName); Map(x => x.ChildId); References(x => x.ChildRef, "ChildId").Cascade.All(); Child Mapping: Id(x => x.NHTestChildId); Map(x => x.ChildName); If I do something like (pseudo code) ... HTestParent parent = new NHTestParent(); parent.ParentName = "Parent 1"; parent.ChildRef.ChildName = "Child 1"; nhibernateSession.SaveOrUpdate(aParent); Commit; ... I get an error: "Invalid index 3 for this SqlParameterCollection with Count=3" If I change the parent 'References' line as follows (i.e. provide the name of the child property I'm pointing at): References(x => x.ChildRef, "ChildId").PropertyRef("NHTestChildId").Cascade.All(); I get the error: "Unable to resolve property: NHTestChildId" So, I tried the 'HasOne()' reference setting, as follows: HasOne<NHTestChild>(x => x.ChildRef).ForeignKey("ChildId").Cascade.All().Fetch.Join(); This results in the save working, but the load fails to find the child. If I inspect the SQL Nhibernate produces I can see that NHibernate is assuming the Primary key of the parent is the link to the child (i.e. load join condition is "parent.NHTestParentId = child.NHTestChildId). The 'ForeignKey' specified appears to be ignored. I can set any value and no error occurs - the join just always fails and no child is returned. I've tried a number of slight variations on the above. It seems like it should be a simple thing to achieve. Any ideas?

  • Moving items from one tableView to another tableView with extra's

    - by Totumus Maximus
    Let's say I have 2 UITableViews next to eachother on an ipad in landscape-mode. Now I want to move multiple items from one tableView to the other. They are allowed to be inserted on the bottom of the other tableView. Both have multiSelection activated. Now the movement itself is no problem with normal cells. But in my program each cell has an object which contains the consolidationState of the cell. There are 4 states a cell can have: Basic, Holding, Parent, Child. Basic = an ordinary cell. Holding = a cell which contains multiple childs but which wont be shown in this state. Parent = a cell which contains multiple childs and are shown directly below this cell. Child = a cell created by the Parent cell. The object in each cell also has some array which contains its children. The object also holds a quantityValue, which is displayed on the cell itself. Now the movement gets tricky. Holding and Parent cells can't move at all. Basic cells can move freely. Child cells can move freely but based on how many Child cells are left in the Parent. The parent will change or be deleted all together. If a Parent cell has more then 1 Child cell left it will stay a Parent cell. Else the Parent has no or 1 Child cell left and is useless. It will then be deleted. The items that are moved will always be of the same state. They will all be Basic cells. This is how I programmed the movement: *First I determine which of the tableViews is the sender and which is the receiver. *Second I ask all indexPathsForSelectedRows and sort them from highest row to lowest. *Then I build the data to be transferred. This I do by looping through the selectedRows and ask their object from the sender's listOfItems. *When I saved all the data I need I delete all the items from the sender TableView. This is why I sorted the selectedRows so I can start at the highest indexPath.row and delete without screwing up the other indexPaths. *When I loop through the selectedRows I check whether I found a cell with state Basic or Child. *If its a Basic cell I do nothing and just delete the cell. (this works fine with all Basic Cells) *If its a Child cell I go and check it's Parent cell immidiately. Since all Child cells are directly below the Parent cell and no other the the Parent's Childs are below that Parent I can safely get the path of the selected Childcell and move upwards and find it's Parent cell. When this Parent cell is found (this will always happen, no exceptions) it has to change accordingly. *The Parent cell will either be deleted or the object inside will have its quantity and children reduced. *After the Parent cell has changed accordingly the Child cell is deleted similarly like the Basic cells *After the deletion of the cells the receiver tableView will build new indexPaths so the movedObjects will have a place to go. *I then insert the objects into the listOfItems of the receiver TableView. The code works in the following ways: Only Basic cells are moved. Basic cells and just 1 child for each parent is moved. A single Basic/Child cell is moved. The code doesn't work when: I select more then 1 or all childs of some parent cell. The problem happens somewhere into updating the parent cells. I'm staring blindly at the code now so maybe a fresh look will help fix things. Any help will be appreciated. Here is the method that should do the movement: -(void)moveSelectedItems { UITableView *senderTableView = //retrieves the table with the data here. UITableView *receiverTableView = //retrieves the table which gets the data here. NSArray *selectedRows = senderTableView.indexPathsForSelectedRows; //sort selected rows from lowest indexPath.row to highest selectedRows = [selectedRows sortedArrayUsingSelector:@selector(compare:)]; //build up target rows (all objects to be moved) NSMutableArray *targetRows = [[NSMutableArray alloc] init]; for (int i = 0; i<selectedRows.count; i++) { NSIndexPath *path = [selectedRows objectAtIndex:i]; [targetRows addObject:[senderTableView.listOfItems objectAtIndex:path.row]]; } //delete rows at active for (int i = selectedRows.count-1; i >= 0; i--) { NSIndexPath *path = [selectedRows objectAtIndex:i]; //check what item you are deleting. act upon the status. Parent- and HoldingCells cant be selected so only check for basic and childs MyCellObject *item = [senderTableView.listOfItems objectAtIndex:path.row]; if (item.consolidatedState == ConsolidationTypeChild) { for (int j = path.row; j >= 0; j--) { MyCellObject *consolidatedItem = [senderTableView.listOfItems objectAtIndex:j]; if (consolidatedItem.consolidatedState == ConsolidationTypeParent) { //copy the consolidated item but with 1 less quantity MyCellObject *newItem = [consolidatedItem copyWithOneLessQuantity]; //creates a copy of the object with 1 less quantity. if (newItem.quantity > 1) { newItem.consolidatedState = ConsolidationTypeParent; [senderTableView.listOfItems replaceObjectAtIndex:j withObject:newItem]; } else if (newItem.quantity == 1) { newItem.consolidatedState = ConsolidationTypeBasic; [senderTableView.listOfItems removeObjectAtIndex:j]; MyCellObject *child = [senderTableView.listOfItems objectAtIndex:j+1]; child.consolidatedState = ConsolidationTypeBasic; [senderTableView.listOfItems replaceObjectAtIndex:j+1 withObject:child]; } else { [senderTableView.listOfItems removeObject:consolidatedItem]; } [senderTableView reloadData]; } } } [senderTableView.listOfItems removeObjectAtIndex:path.row]; } [senderTableView deleteRowsAtIndexPaths:selectedRows withRowAnimation:UITableViewRowAnimationTop]; //make new indexpaths for row animation NSMutableArray *newRows = [[NSMutableArray alloc] init]; for (int i = 0; i < targetRows.count; i++) { NSIndexPath *newPath = [NSIndexPath indexPathForRow:i+receiverTableView.listOfItems.count inSection:0]; [newRows addObject:newPath]; DLog(@"%i", i); //scroll to newest items [receiverTableView setContentOffset:CGPointMake(0, fmaxf(receiverTableView.contentSize.height - recieverTableView.frame.size.height, 0.0)) animated:YES]; } //add rows at target for (int i = 0; i < targetRows.count; i++) { MyCellObject *insertedItem = [targetRows objectAtIndex:i]; //all moved items will be brought into the standard (basic) consolidationType insertedItem.consolidatedState = ConsolidationTypeBasic; [receiverTableView.ListOfItems insertObject:insertedItem atIndex:receiverTableView.ListOfItems.count]; } [receiverTableView insertRowsAtIndexPaths:newRows withRowAnimation:UITableViewRowAnimationNone]; } If anyone has some fresh ideas of why the movement is bugging out let me know. If you feel like you need some extra information I'll be happy to add it. Again the problem is in the movement of ChildCells and updating the ParentCells properly. I could use some fresh looks and outsider ideas on this. Thanks in advance. *updated based on comments

  • Calling "Base-Getter" in Overriding Getter of Property

    - by scherand
    I have a base class "Parent" like this: using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication1 { class Parent { private int parentVirtualInt = -1; public virtual int VirtualProperty { get { return parentVirtualInt; } set { if(parentVirtualInt != value) { parentVirtualInt = value; } } } } } and a child class like this: using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication1 { class Child : Parent { public override int VirtualProperty { get { if(base.VirtualProperty > 0) { throw new ApplicationException("Dummy Ex"); } return base.VirtualProperty; } set { if(base.VirtualProperty != value) { base.VirtualProperty = value; } } } } } Note that the getter in Child is calling the getter of Parent (or at least this is what I intend). I now use the "Child" class by instantiating it, assigning a value (let's say 4) to its VirtualProperty and then reading the property again. Child c = new Child(); c.VirtualProperty = 4; Console.Out.WriteLine("Child.VirtualProperty: " + c.VirtualProperty); When I run this, I obviously get an ApplicationException saying "Dummy Ex". But if I set a breakpoint on the line if(base.VirtualProperty > 0) in Child and check the value of base.VirtualProperty (by hovering the mouse over it) before the exception can be thrown (I assume(d)), I already get the Exception. From this I convey that the statement base.VirtualProperty in the "Child-Getter calls itself"; kind of. What I would like to achieve is the same behavior I get when I change the definition of parentVirutalInt (in Parent) to protected and use base.parentVirtualInt in the Getter of Child instead of base.VirtualProperty. And I don't yet see why this is not working. Can anybody shed some light on this? I feel that overridden properties behave differently than overridden methods? By the way: I am doing something very similar with subclassing a class I do not have any control over (this is the main reason why my "workaround" is not an option). Kind regards
