  • How to highlight ListView item on touch?

    - by AndroidNoob
    I have a simple ListView and I want each of it items to be highlighted on user's touch. I thought this should happen by default but it isn't. Can you advice? ListView xml: <ListView android:id="@+id/list_view" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:divider="#206600" android:dividerHeight="2dp" android:smoothScrollbar="true" android:background="#ffffff" > </ListView> And code of my Adapter: private class MyAdapter extends ArrayAdapter<Task> { private LayoutInflater mInflater; public MyAdapter(Context context, int resource, List<Task> list) { super(context, resource, list); mInflater = LayoutInflater.from(context); } @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { v = mInflater.inflate(R.layout.list_item, null); } Task task = taskList.get(position); /* Setup views from your layout using data in Object here */ return v; }

  • Mutually exclusive regular expressions

    - by CaptnCraig
    If I have a list of regular expressions, is there an easy way to determine that no two of them will both return a match for the same string? That is, the list is valid if and only if for all strings a maximum of one item in the list will match the entire string. It seems like this will be very hard (maybe impossible?) to prove definitively, but I can't seem to find any work on the subject. The reason I ask is that I am working on a tokenizer that accepts regexes, and I would like to ensure only one token at a time can match the head of the input.

  • a nicer way to create structs in a loop

    - by sandra
    Hi guys, I haven't coded in C++ in ages. And recently, I'm trying to work on something involving structs. Like this typedef struct{ int x; int y; } Point; Then in a loop, I'm trying to create new structs and put pointers to them them in a list. Point* p; int i, j; while (condition){ // compute values for i and j with some function... p = new Point; p* = {i, j}; //initialize my struct. list.append(p); //append this pointer to my list. } Now, my question is it possible to simplify this? I mean, the pointer variable *p outside of the loop and calling p = new Point inside the loop. Isn't there a better/nicer syntax for this?

  • Assign multiple css classes to a table element in Rails

    - by Eric K
    I'm trying to style a table row using both cycle and a helper, like shown: <tr class= <%= cycle("list-line-odd #{row_class(item)}", "list-line-even #{row_class(item)}")%> > However, when I do this, the resulting HTML is: <tr class = "list-line-odd" lowest-price> with the return from the helper method not enclosed in the quotes, and therefore not recognized. Here's the helper I'm using: def row_class(item) if item.highest_price > 0 and item.lowest_price > 0 and item.highest_price != item.lowest_price if item.current_price >= item.highest_price "highest-price" elsif item.current_price <= item.lowest_price "lowest-price" end end end I must be missing something obvious, but I just can't figure out how to wrap both the result of cycle and the helper method return in the same set of quotes. Any help would be greatly appreciated!

  • Inserting new argument to table through search form of another table

    - by owca
    In my database I have a form for searching products (fields : id, name, manufacturer_id[set to display manufacturer's name], category_id, price). I would like to have the ability of adding manufacturers through this form. So I've created vba script but it does not work. Still when I enter new name it gives me prompt to "Select element from the list". What am I doing wrong ? Private Sub manufacturer_id_NotInTheList(NewData As String, Response As Integer) Dim strSQL As String, strInfo As String strInfo = "Manufacturer " & NewData & " is not on the list." & vbCrLf & "Add?" If MsgBox(strInfo, vbYesNo + vbQuestion, "Element not on the list") = vbYes Then strSQL = "INSERT INTO manufacturer (name, country, id_distributor) VALUES ('" & NewData & "','Undefined', '0');" DoCmd.SetWarnings (False) DoCmd.RunSQL strSQL Response = acDataErrAdded Else Response = acDataErrContinue NewData = "" Me.manufacturer_id.Text = "" End If End Sub

  • Drools rule to filter element with a numeric property below a percentage of the total

    - by Mario
    Hello, I have just started using Drools on a small project and now I need to write a rule a bit complex and I don't really know what's the best way to do it. I am applying this rule to a list of objects of the same type (this class have a property called numberOfExecutions). I need to check for each element of the list if the numberOfExecutions of that element is bigger than 5% of the total numberOfExecutions (the sum of numberOfExecutions of all the elements in the list). I could not think of a nice way to implement this in drools so far, do you have a suggestion?

  • Fake sent email appear in my sent items folder

    - by Mike
    I have an email listed as being sent by my outlook account that I did not send. In order to figure out who it was sent to, I forwarded it to the same address (hotmail account) and received a reply that there was no such address. I've tried looking up that address and it does not appear to exist. Can someone fake an email and have it appear in my outlook sent items folder as being sent by me? How can I tell who did this?

  • WPF Binding not updating when binded object is updated

    - by Chris Klepeis
    I'm trying to bind to a custom control like so: <my:GanttChartTaskListView Name="ganttChartTaskListView1" ItemsSource="{Binding Source={x:Static local:TaskCollection.taskList}}" /> In my WPF Window constructor I add add an item to my taskList, when it loads I can see that item in my custom control, however, when I subsequently add items it does not update. I tried setting Mode=TwoWay, however, then it says the "Path" is required and I'm not familiar with binding like that (this is new to me). Here is my TaskCollection class: namespace ProjectManager { public static class TaskCollection { private static List<TaskItem> _taskList = new List<TaskItem>(); public static List<TaskItem> taskList { get {return _taskList; } set { _taskList = value; } } } } Any ideas? Is there a better / easier way to do this?

  • File types and locations (if any) to exclude from AntiVirus scanning?

    - by CAD bloke
    Should I add any file types to my anti-virus's file type exclusion list? If so, which types? Should I add any locations (specifically for Windows 7) to an exclusion list? If so, which locations? Google found me a few references like http://support.microsoft.com/kb/822158 http://support.microsoft.com/kb/943556 and some site purporting to conduct expert sex changes but haven't found anything particularly confidence-inspiring.

  • Build multiple executables with small changes in objects

    - by Morgoth
    Consider the following Makefile COMP = compiler OBJECTS = file1 \ file2 \ file3 \ file4 \ file5_suffix \ file6 \ file7 \ file8 \ file9_suffix \ file10 all: $(OBJECTS) $(COMP) $(OBJECTS) -o bin/executable_suffix Is there an easy way to compile multiple executables for different values of suffix? For example, the equivalent of COMP = compiler OBJECTS1 = file1 \ file2 \ file3 \ file4 \ file5_s1 \ file6 \ file7 \ file8 \ file9_s1 \ file10 OBJECTS2 = file1 \ file2 \ file3 \ file4 \ file5_s2 \ file6 \ file7 \ file8 \ file9_s2 \ file10 all: $(OBJECTS1) $(OBJECTS2) $(COMP) $(OBJECTS1) -o bin/executable_s1 $(COMP) $(OBJECTS2) -o bin/executable_s2 but without redefining the whole list of objects? In the real life case I am dealing with, there might be 50+ objects and a dozen binaries to build, with only small changes between the object list each time, so it would be nice not to have to list all the objects each time.

  • SSRS 2005 Keep textbox and textfield together when page break occurs

    - by EKet
    Problem I don't have a details row or anything. I have simply a body and I dragged on textboxes for labeling textfields from my dataset. The problem is when one of the fields has too much data for the current page, it "page-breaks" at the start of the field leaving the textbox (label for the field) behind on the previous page. What I've tried Put the data field and the textbox label a) inside a rectangle - didn't work b) inside a list and the list inside a rectangle - didn't work c) inside a list with keep together property set to TRUE or FALSE - didn't work Question How would I group the textbox and the textfield so that regardless of where the pagebreak happens it includes its label?

  • Jquery autosuggest google maps - Load on selection

    - by user1738522
    At the moment, the Google map code works like this: When you start typing in the input box it loads a list of suggestions. Then when you click on one of these options from the list, it puts it into the input box. However, THEN you still have to click find to load up the result. I want to have it so when you click on an option from the autosuggest list, it automatically loads the result, without having to click "find" afterwards. This is the code I am working with. I hope I explained this question correctly. http://jsfiddle.net/BxG9H/

  • Sharing state/changes across ViewModels

    - by joshperry
    I have an App which has a Tasks tab and a Projects tab. I decided to make a separate ViewModel for each of the tabs, TasksViewModel and ProjectsViewModel. The Tasks tab has a new task area with an associated project pulldown and the Projects tab (obviously) has a list of projects. What I'd like is for the pulldown on the Tasks tab to share the same collection as the Projects tab list so that any time I add or remove a project on the Projects tab the list on the Tasks tab is up to date automatically. This worked well with a single ViewModel but it was beginning to become quite unruly. Should I not have split into two ViewModels? Is there a common method of sharing data like this? Perhaps pass the same ObservableCollection<Project> into each of the ViewModels? Perhaps some type of notification back to the TasksViewModel along the lines of ICollectionChanged. Appreciate any insight/input!

  • Dijit Combobox filter autocomplete

    - by Apps
    I'm using dijit combobox for populating a JSON List. Also I'm using ItemFileReadStore for getting the JSON data from the server. Once the data is downloaded, when I click on the combobox it shows all the data. But I don't want the user to see all the data. The user should see the list only when he types something. I tried using queryExpr parameter-${0}*. But at that time the list is not populated.Can someone please help me to fix it? Any help will be greatly appreciated Thanks, Apps

  • Facebook Open Graph - Grab how many times a page has been liked?

    - by DoMx
    I have a site that allows users to create a saying and then users "like" those sayings on Facebook. http://www.likeylikey.net/ I got a friend to throw up this simple code in less than 2 hours so it's basic. He knows little to nothing regarding the Open Graph API. Basically, I want to know how I can programmatically store how many times a page has been liked so I can list a "Top 10, most liked pages" list. Right now the index shows a list of all created pages and now I just wish to show the 10 most liked but I need a way of pulling that information from Facebook. Is this possible?

  • How to expose a control collection to a property grid at design time

    I have a custom control that with a property that is a collection of custom object. This custom object hava a reference to some component/controls. When at design time I tray to add an item to the collection and select the object, VS tells me that the control is not serializable.

  • Sorting in Matlab

    - by smichak
    Hi, I would like to sort elements in a comma-separated list. The elements in the list are structs and I would like the list to be sorted according to one of the fields in the struct. For example, given the following code: L = {struct('obs', [1 2 3 4], 'n', 4), struct('obs', [6 7 5 3], 'n', 2)}; I would want to have a way to sort L by the field 'n'. Matlab's sort function only works on matrices or arrays and on lists of strings (not even lists of numbers). Any ideas on how that may be achieved? Thanks, Micha
