• Fixing merge conflicts?

  - by user291701

  I have two remote branches, "grape" and "master". I'm currently on "grape". Now I switch to "master": git checkout master Now I want to pull all changes from "grape" into "master" - is this the way to do it?: git merge origin grape It's my understanding that git will then pull all the current state of the remote branch "grape" into my local copy of "master". It will try to auto-merge for me. If there are conflicts, the files in conflict will have some conflict text actually injected into the file. I then have to go into those files, and delete the chunk I don't want (essentially telling git how to merge these files). For each file in conflict, do I add and commit the changes again?: git add problemfile1.txt git commit -m "Fixed merge conflict." git add problemfile2.txt git commit -m "Fixed another merge conflict." ... after I've fixed all the merge conflicts like above, do I just push to "master" again to finish up the process?: git push origin master or is there something else we need to do when we get into this conflict state? Thank you

• What is the subject of Rspecs its method

  - by Steve Weet

  When you use the its method in rspec like follows its(:code) { should eql(0)} what is 'its' referring to. I have the following spec that works fine describe AdminlwController do shared_examples_for "valid status" do it { should be_an_instance_of(Api::SoapStatus) } it "should have a code of 0" do subject.code.should eql(0) end it "should have an empty errors array" do subject.errors.should be_an(Array) subject.errors.should be_empty end #its(:code) { should eql(0)} end describe "Countries API Reply" do before :each do co1 = Factory(:country) co2 = Factory(:country) @result = invoke :GetCountryList, "empty_auth" end subject { @result } it { should be_an_instance_of(Api::GetCountryListReply) } describe "Country List" do subject {@result.country_list} it { should be_an_instance_of(Array) } it { should have(2).items } it "should have countries in the list" do subject.each {|c| c.should be_an_instance_of(Api::Country)} end end describe "result status" do subject { @result.status } it_should_behave_like "valid status" end end However if I then uncomment the line with its(:code) then I get the following output AdminlwController Countries API Reply - should be an instance of Api::GetCountryListReply AdminlwController Countries API Reply Country List - should be an instance of Array - should have 2 items - should have countries in the list AdminlwController Countries API Reply result status - should be an instance of Api::SoapStatus - should have a code of 0 - should have an empty errors array AdminlwController Countries API Reply result status code - should be empty (FAILED - 1) 1) NoMethodError in 'AdminlwController Countries API Reply result status code should be empty' undefined method code for <AdminlwController:0x40fc4dc> /Users/steveweet/romad_current/romad/spec/controllers/adminlw_controller_spec.rb:29: Finished in 0.741599 seconds 8 examples, 1 failure It seems as if "its" is referring to the subject of the whole test, namely AdminLwController rather than the current subject. Am I doing something wrong or is this an Rspec oddity?

• How to build a control programatically?

  - by W_K

  I have custom control written in Java. For the sake of simplicity lets assume that it looks like this: public class HelloworldControl extends UIComponentBase { @Override public void decode(FacesContext context) { String cid = this.getClientId(context); ... super.decode(context); } @Override public void encodeBegin(FacesContext context) throws IOException { ResponseWriter writer = context.getResponseWriter(); writer.writeText("Hello world!", this); // I want a view!! } @Override public void encodeEnd(FacesContext context) throws IOException { ResponseWriter writer = context.getResponseWriter(); ... } public void restoreState(FacesContext context, Object state) { Object values[] = (Object[]) state; ... super.restoreState(context, values[0]); } public Object saveState(FacesContext context) { Object values[] = ... } } I would like to add programatically child control to it. For example I would like a child view control to render a view just under the Hellow world text. How can i do this? What is the standard procedure to build dynamically a control? To put it simply - I want programatically build a hierarchy of standard components and I want to attach it to my control.

• ListView setOnItemClickListener in ListFragment not working

  - by Siddarth Kaki

  I am developing an app that uses ActionBar tabs to display a list of options through ListFragment. The list (and ListFragment) display without a problem, but the ListView's setOnItemClickListener doesn't seems to work, as nothing happens when an item in the list is clicked. Here's the code for the ListFragment class: package XXX.XXX; public class AboutFrag extends SherlockListFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.aboutfrag, container, false); ListView lv = (ListView) view.findViewById(android.R.id.list); String[] items = new String[] {"About 1", "About 2", "About 3"}; lv.setAdapter(new ArrayAdapter<String>(getActivity(), R.layout.list_item, items)); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { switch (position) { case 0: Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://google.com")); startActivityForResult(browserIntent, 0); break; case 1: Intent browserIntent2 = new Intent(Intent.ACTION_VIEW, Uri.parse("http://wikipedia.org")); startActivityForResult(browserIntent2, 0); break; case 2: Intent browserIntent3 = new Intent(Intent.ACTION_VIEW, Uri.parse("http:/android.com"); startActivityForResult(browserIntent3, 0); break; } } }); return view; } } I'm assuming it does not work because the class returns the view object, so the FragmentActivity can't run the listener code, so does anyone know how to make this work? By the way, I am using ActionBarSherlock. Thanks in advance!!!

• jQuery tokeninput plugin + passing id to another tokeninput url

  - by Elson Solano

  I am using a jquery plugin called jQuery Tokeninput http://loopj.com/jquery-tokeninput/ and I am having a logic issue. var country_id = ""; jQuery("#demo-input-prevent-duplicates").tokenInput(host+"/forms/campaign_location.php?action=country", { theme: "facebook", hintText: "Enter a Country...", placeholder: "Enter a Country...", preventDuplicates: true, onAdd: function(item) { country_id = item.id; }, onDelete: function(){ hideElements(); }, tokenDelimiter: "|", }); My question here is how would I pass the value of country_id to the parameter of the below code. I'm not seeing how to do this one on the jquery tokeninput documentation. jQuery("#targ_state").tokenInput(host+"/forms/campaign_location.php?action=stateorprovince&cid="+country_id, { theme: "facebook", preventDuplicates: true, hintText: "Enter a State or Province...", placeholder: "Enter a State or Province..." }); If you'll look on this part of the code, I am passing the country_id that was generated above on the "onAdd". This doesn't work though. jQuery("#targ_state").tokenInput(host+"/forms/campaign_location.php?action=stateorprovince&cid="+country_id .... How would I do that one? Your help would be greatly appreciated and of course, rewarded! Thanks! :-)

• Problem with inheritance and List<>

  - by Jagd

  I have an abstract class called Grouping. I have a subclass called GroupingNNA. public class GroupingNNA : Grouping { // blah blah blah } I have a List that contains items of type GroupingNNA, but is actually declared to contain items of type Grouping. List<Grouping> lstGroupings = new List<Grouping>(); lstGroupings.Add( new GroupingNNA { fName = "Joe" }); lstGroupings.Add( new GroupingNNA { fName = "Jane" }); The Problem: The following LINQ query blows up on me because of the fact that lstGroupings is declared as List< Grouping and fName is a property of GroupingNNA, not Grouping. var results = from g in lstGroupings where r.fName == "Jane" select r; Oh, and this is a compiler error, not a runtime error. Thanks in advance for any help on this one! More Info: Here is the actual method that won't compile. The OfType() fixed the LINQ query, but the compiler doesn't like the fact that I'm trying to return the anonymous type as a List< Grouping. private List<Grouping> ApplyFilterSens(List<Grouping> lstGroupings, string fSens) { // This works now! Thanks @Lasse var filtered = from r in lstGroupings.OfType<GroupingNNA>() where r.QASensitivity == fSens select r; if (filtered != null) { **// Compiler doesn't like this now** return filtered.ToList<Grouping>(); } else return new List<Grouping>(); }

• Quickly or concisely determine the longest string per column in a row-based data collection

  - by ccornet

  Judging from the failure of my last inquiry, I need to calculate and preset the widths of a set of columns in a table that is being made into an Excel file. Unfortunately, the string data is stored in a row-based format, but the widths must be calculated in a column-based format. The data for the spreadsheets are generated from the following two collections: var dictFiles = l.Items.Cast<SPListItem>().GroupBy(foo => foo.GetSafeSPValue("Category")).ToDictionary(bar => bar.Key); StringDictionary dictCols = GetColumnsForItem(l.Title); Where l is an SPList whose title determines which columns are used. Each SPListItem corresponds to a row of data, which are sorted into separate worksheets based on Category (hence the dictionary). The second line is just a simple StringDictionary that has the column name (A, B, C, etc.) as a key and the corresponding SPListItme field display name as the corresponding value. So for each Category, I enumerate through dictFiles[somekey] to get all the rows in that sheet, and get the particular cell data using SPListItem.Fields[dictCols[colName]]. What I am asking is, is there a quick or concise method, for any one dictFiles[somekey], to retrieve a readout of the longest string in each column provided by dictCols? If it is impossible to get both quickness and conciseness, I can settle for either (since I always have the O(n*m) route of just enumerating the collection and updating an array whenever strCurrent.Length strLongest.Length). For example, if the goal table was the following... Item# Field1 Field2 Field3 1 Oarfish Atmosphere Pretty 2 Raven Radiation Adorable 3 Sunflower Flowers Cute I'd like a function which could cleanly take the collection of items 1, 2, and 3 and output in the correct order... Sunflower, Atmosphere, Adorable Using .NET 3.5 and C# 3.0.

• Enforce link in Team foundation server bug work item for duplicates

  - by Tewr

  We have just started out with Team Foundation Server 2008 / Visual Studio Team System and we are pleased to find how we can export and modify work items to our needs. However, this last thing that would make the setup perfect for us has proved somewhat difficult: We have exported the Bug work item type and have made modifications to it to appear differently to different groups of users. We do, however, see a potential problem in non-developers reporting bugs which turn out to be duplicates. We would like to enforce that users who close a ticket with resolved reason:duplicate also creates a link to the bug which is perceived as the first bug report. I have looked at System.RelatedLinkCount, and put the rule <FIELD type="Integer" name="RelatedLinkCount" refname="System.RelatedLinkCount"> <WHEN field="Microsoft.VSTS.Common.ResolvedReason" value="duplicate"> <PROHIBITEDVALUES> <LISTITEM value="0" /> </PROHIBITEDVALUES> </WHEN> </FIELD> However, when I try to put anything in that scope, the importer tells me that System.RelatedLinkCount does not accept the rule, no matter what I put, but the rule above shows what I am trying to do (even though the most preferable rule would also check that the bug that I link to is not a duplicate as well, though this is overkill :P) Has anyone else tried to enforce rules like this in work items? Is there another approach to solving the same issue? I am thankful for any thoughts on the matter.

• Angular JS pagination after data loaded

  - by Federico Bucchi

  do you have any example of Angular JS elements pagination loaded from I file? I found this example: http://jsfiddle.net/SAWsA/11/ Now, instead of having this: $scope.items = [ {"id":"1","name":"name 1","description":"description 1","field3":"field3 1","field4":"field4 1","field5 ":"field5 1"}, {"id":"2","name":"name 2","description":"description 1","field3":"field3 2","field4":"field4 2","field5 ":"field5 2"}, {"id":"3","name":"name 3","description":"description 1","field3":"field3 3","field4":"field4 3","field5 ":"field5 3"}, {"id":"4","name":"name 4","description":"description 1","field3":"field3 4","field4":"field4 4","field5 ":"field5 4"}, {"id":"5","name":"name 5","description":"description 1","field3":"field3 5","field4":"field4 5","field5 ":"field5 5"}, {"id":"6","name":"name 6","description":"description 1","field3":"field3 6","field4":"field4 6","field5 ":"field5 6"}, {"id":"7","name":"name 7","description":"description 1","field3":"field3 7","field4":"field4 7","field5 ":"field5 7"}, {"id":"8","name":"name 8","description":"description 1","field3":"field3 8","field4":"field4 8","field5 ":"field5 8"}, {"id":"9","name":"name 9","description":"description 1","field3":"field3 9","field4":"field4 9","field5 ":"field5 9"}, {"id":"10","name":"name 10","description":"description 1","field3":"field3 10","field4":"field4 10","field5 ":"field5 10"}, {"id":"11","name":"name 11","description":"description 1","field3":"field3 11","field4":"field4 11","field5 ":"field5 11"}, {"id":"12","name":"name 12","description":"description 1","field3":"field3 12","field4":"field4 12","field5 ":"field5 12"}, {"id":"13","name":"name 13","description":"description 1","field3":"field3 13","field4":"field4 13","field5 ":"field5 13"}, {"id":"14","name":"name 14","description":"description 1","field3":"field3 14","field4":"field4 14","field5 ":"field5 14"}, {"id":"15","name":"name 15","description":"description 1","field3":"field3 15","field4":"field4 15","field5 ":"field5 15"}, {"id":"16","name":"name 16","description":"description 1","field3":"field3 16","field4":"field4 16","field5 ":"field5 16"}, {"id":"17","name":"name 17","description":"description 1","field3":"field3 17","field4":"field4 17","field5 ":"field5 17"}, {"id":"18","name":"name 18","description":"description 1","field3":"field3 18","field4":"field4 18","field5 ":"field5 18"}, {"id":"19","name":"name 19","description":"description 1","field3":"field3 19","field4":"field4 19","field5 ":"field5 19"}, {"id":"20","name":"name 20","description":"description 1","field3":"field3 20","field4":"field4 20","field5 ":"field5 20"} ]; I have to use something generated by: $http.get('/json/mocks/apps/applications.json') .then(function (result) { $scope.items = result.data.applications; }); How would you create the pagination waiting for the data loaded from $http.get?

• select2: "text is undefined" when getting json using ajax

  - by user3046715

  I'm having an issue when getting json results back to select2. My json does not return a result that has a "text" field so need to format the result so that select2 accepts "Name". This code works if the text field in the json is set to "text" but in this case, I cannot change the formatting of the json result (code outside my control). $("#e1").select2({ formatNoMatches: function(term) {return term +" does not match any items." }, ajax: { // instead of writing the function to execute the request we use Select2's convenient helper url: "localhost:1111/Items.json", dataType: 'jsonp', cache: true, quietMillis: 200, data: function (term, page) { return { q: term, // search term p: page, s: 15 }; }, results: function (data, page) { // parse the results into the format expected by Select2. var numPages = Math.ceil(data.total / 15); return {results: data.Data, numPages: numPages}; } } }); I have looked into the documentation and found some statements you can put into the results such as text: 'Name', but I am still getting "text is undefined". Thanks for any help.

• tk: how to invoke it just to display something, and return to the main program?

  - by max

  Sorry for the noob question but I really don't understand this. I'm using python / tkinter and I want to display something (say, a canvas with a few shapes on it), and keep it displayed until the program quits. I understand that no widgets would be displayed until I call tkinter.tk.mainloop(). However, if I call tkinter.tk.mainloop(), I won't be able to do anything else until the user closes the main window. I don't need to monitor any user input events, just display some stuff. What's a good way to do this without giving up control to mainloop? EDIT: Is this sample code reasonable: class App(tk.Tk): def __init__(self, sim): self.sim = sim # link to the simulation instance self.loop() def loop(): self.redraw() # update all the GUI to reflect new simulation state sim.next_step() # advance simulation another step self.after(0, self.loop) def redraw(): # get whatever we need from self.sim, and put it on the screen EDIT2 (added after_idle): class App(tk.Tk): def __init__(self, sim): self.sim = sim # link to the simulation instance self.after_idle(self.preloop) def preloop(): self.after(0, self.loop) def loop(): self.redraw() # update all the GUI to reflect new simulation state sim.next_step() # advance simulation another step self.after_idle(self.preloop) def redraw(): # get whatever we need from self.sim, and put it on the screen

• A generic C++ library that provides QtConcurrent functionality?

  - by Lucas

  QtConcurrent is awesome. I'll let the Qt docs speak for themselves: QtConcurrent includes functional programming style APIs for parallel list processing, including a MapReduce and FilterReduce implementation for shared-memory (non-distributed) systems, and classes for managing asynchronous computations in GUI applications. For instance, you give QtConcurrent::map() an iterable sequence and a function that accepts items of the type stored in the sequence, and that function is applied to all the items in the collection. This is done in a multi-threaded manner, with a thread pool equal to the number of logical CPU's on the system. There are plenty of other function in QtConcurrent, like filter(), filteredReduced() etc. The standard CompSci map/reduce functions and the like. I'm totally in love with this, but I'm starting work on an OSS project that will not be using the Qt framework. It's a library, and I don't want to force others to depend on such a large framework like Qt. I'm trying to keep external dependencies to a minimum (it's the decent thing to do). I'm looking for a generic C++ framework that provides me with the same/similar high-level primitives that QtConcurrent does. AFAIK boost has nothing like this (I may be wrong though). boost::thread is very low-level compared to what I'm looking for. I know C# has something very similar with their Parallel Extensions so I know this isn't a Qt-only idea. What do you suggest I use?

• How to optimize paging for large in memory database

  - by snakefoot

  I have an application where the entire database is implemented in memory using a stl-map for each table in the database. Each item in the stl-map is a complex object with references to other items in the other stl-maps. The application works with a large amount of data, so it uses more than 500 MByte RAM. Clients are able to contact the application and get a filtered version of the entire database. This is done by running through the entire database, and finding items relevant for the client. When the application have been running for an hour or so, then Windows 2003 SP2 starts to page out parts of the RAM for the application (Eventhough there is 16 GByte RAM on the machine). After the application have been partly paged out then a client logon takes a long time (10 mins) because it now generates a page fault for each pointer lookup in the stl-map. I can see it is possible to tell Windows to lock memory in RAM, but this is generally only recommended for device drivers, and only for "small" amounts of memory. I guess a poor mans solution could be to loop through the entire memory database, and thus tell Windows we are still interested in keeping the datamodel in RAM. I guess another poor mans solution could be to disable the pagefile completely on Windows. I guess the expensive solution would be a SQL database, and then rewrite the entire application to use a database layer. Then hopefully the database system will have implemented means to for fast access. Are there other more elegant solutions ?

• Need a VB Script to check if service exist

  I want to write a VBS script which will check if specific service is installed/exist or not locally.

• Is there a design pattern that expresses objects (an their operations) in various states?

  - by darren

  Hi I have a design question about the evolution of an object (and its state) after some sequence of methods complete. I'm having trouble articulating what I mean so I may need to clean up the question based on feedback. Consider an object called Classifier. It has the following methods: void initialise() void populateTrainingSet(TrainingSet t) void pupulateTestingSet(TestingSet t) void train() void test() Result predict(Instance i) My problem is that these methods need to be called in a certain order. Futher, some methods are invalid until a previous method is called, and some methods are invalid after a method has been called. For example, it would be invalid to call predict() before test() was called, and it would be invalid to call train() after test() was called. My approach so far has been to maintain a private enum that represents the current stateof the object: private static enum STATE{ NEW, TRAINED, TESTED, READY}; But this seems a bit cloogy. Is there a design pattern for such a problem type? Maybe something related to the template method.

• How to find all initializations of instance variables in a Java package?

  - by Hank Gay

  I'm in the midst of converting a legacy app to Spring. As part of the transition, we're converting our service classes from an "instantiate new ones whenever you need one" style to a Springleton style, so I need a way to make sure they don't have any state. I'm comfortable on the *nix command-line, and I have access to IntelliJ (this strikes me as a good fit for Structural Search and Replace, if I could figure out how to use it), and I could track down an Eclipse install, if that would help. I just want to make absolutely sure I've found all the possible problems. UPDATE: Sorry for the confusion. I don't have a problem finding places where the old constructor was being called. What I'm looking for is a "bullet-proof" why to search all 100+ service classes for any sort of internal state. The most obvious one I could think of (and the only one I've really found so far) is cases where we use memoization in the classes, so they have instance variables that get initialized internally instead of via Spring. This means that when the same Springleton gets used for different requests, data can leak between them. Thanks.

• Images from url to listview

  - by Andres

  I have a listview which I show video results from YouTube. Everything works fine but one thing I noticed is that the way it works seems to be a bit slow and it might be due to my code. Are there any suggestions on how I can make this better? Maybe loading the images directly from the url instead of using a webclient? I am adding the listview items in a loop from video feeds returned from a query using the YouTube API. The piece of code which I think is slowing it down is this: Feed<Video> videoFeed = request.Get<Video>(query); int i = 0; foreach (Video entry in videoFeed.Entries) { string[] info = printVideoEntry(entry).Split(','); WebClient wc = new WebClient(); wc.DownloadFile(@"http://img.youtube.com/vi/" + info[0].ToString() + "/hqdefault.jpg", info[0].ToString() + ".jpg"); string[] row1 = { "", info[0].ToString(), info[1].ToString() }; ListViewItem item = new ListViewItem(row1, i); YoutubeList.Items.Add(item); imageListSmall.Images.Add(Bitmap.FromFile(info[0].ToString() + @".jpg")); imageListLarge.Images.Add(Bitmap.FromFile(info[0].ToString() + @".jpg")); } public static string printVideoEntry(Video video) { return video.VideoId + "," + video.Title; } As you can see I use a Webclient which downloads the images so then I can use them as image in my listview. It works but what I'm concerned about is speed..any suggestions? maybe a different control all together?

• Check a list of packages to install with apt-get

  - by Joel

  I am writing a post-install script for Ubuntu in Perl (same script as seen here). One of the steps is to install a list of packages. The problem is that if apt-get install fails in some of many different ways for any one of the packages the script dies badly. I would like to prevent that from happening. This happens because of the ways that apt-get install fails for packages that it doesn't like. For example when I try to install a nonsense word (i.e. typed in the wrong package name) $ sudo apt-get install oblihbyvl Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package oblihbyvl but if instead the package name has been obsoleted (installing handbrake from ppa) $ sudo apt-get install handbrake Reading package lists... Done Building dependency tree Reading state information... Done Package handbrake is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'handbrake' has no installation candidate $ apt-cache search handbrake handbrake-cli - versatile DVD ripper and video transcoder - command line handbrake-gtk - versatile DVD ripper and video transcoder - GTK GUI I have tried parsing the results of apt-cache and apt-get -s install to try to catch all possibilities before doing the install, but I seem to keep finding new ways to allow failures to continue to the actual install system command. My question is, is there some facility either in Perl (e.g. a module, though I would like to avoid installing modules if possible as this is supposed to be the first thing run after a new install of Ubuntu) or apt-* or dpkg that would let me be sure that the packages are all available to be installed before installing and if not fail gracefully in some way that lets the user decide what to do?

• Unable to diligently close the excel process running in memory

  - by NewAutoUser

  I have developed a VB.Net code for retrieving data from excel file .I load this data in one form and update it back in excel after making necessary modifications in data. This complete flow works fine but most of the times I have observed that even if I close the form; the already loaded excel process does not get closed properly. I tried all possible ways to close it but could not be able to resolve the issue. Find below code which I am using for connecting to excel and let me know if any other approach I may need to follow to resolve this issue. Note: I do not want to kill the excel process as it will kill other instances of the excel Dim connectionString As String connectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & ExcelFilePath & "; Extended Properties=excel 8.0; Persist Security Info=False" excelSheetConnection = New ADODB.Connection If excelSheetConnection.State = 1 Then excelSheetConnection.Close() excelSheetConnection.Open(connectionString) objRsExcelSheet = New ADODB.Recordset If objRsExcelSheet.State = 1 Then objRsExcelSheet.Close() Try If TestID = "" Then objRsExcelSheet.Open("Select * from [" & ActiveSheet & "$]", excelSheetConnection, 1, 1) Else objRsExcelSheet.Open("Select Test_ID,Test_Description,Expected_Result,Type,UI_Element,Action,Data,Risk from [" & ActiveSheet & "$] WHERE TEST_Id LIKE '" & TestID & ".%'", excelSheetConnection, 1, 1) End If getExcelData = objRsExcelSheet Catch errObj As System.Runtime.InteropServices.COMException MsgBox(errObj.Message, , errObj.Source) Return Nothing End Try excelSheetConnection = Nothing objRsExcelSheet = Nothing

• populate drop-down values dynamically using Ajax

  - by abhishek

  Hi, I have 3 drop-downs. 1st drop-down contains some values when the page loads. I need to populate 2 nd drop-down based on the value selected in 1st dropdown. Similarly, I need to populate 3 nd drop-down based on the value selected in 1st and 2nd dropdown. Initially I tried like this. <h:selectOneMenu value="#{stu.country}" > <f:selectItems value="#{bean.allCountries}" /> <a4j:support event="onchange" action="#{bean.retrieveStates(stu.country)}" reRender="states_dropDown"></a4j:support> </h:selectOneMenu> //ly, for 2nd drop-down <h:selectOneMenu id="states_dropDown" value="#{stu.state}" > <f:selectItems value="#{bean.allStates}" /> <a4j:support event="onchange" action="#{bean.retrieveCities(stu.country,stu.state)}" reRender="City_dropDown"></a4j:support> </h:selectOneMenu> Some times this code works fine. But some times it doesn't invoke managed bean method. Can you please help??

• Dynamically disable custom (VBA) Excel context menu buttons?

  - by Lopsided

  The Scenario Hi guys, I am about to add a few custom controls to the cell context menu in my Excel workbook using the instructions found on this MSDN page. The only problem I am having is that I need the items to only be enabled for a specific column/range of cells. I've looked around, and I've been unable to find any steps for this--there are some for VSTO development (written in C#), but that is not what I need. I plan to write this using the VBA IDE built into Office, and perhaps a bit of XML using the Custom UI Editor. The Question So basically, I'm looking for a way to run a function at the time the context menu is called (i.e., upon right-click) that validates the selection to make sure it is in the appropriate column. If it isn't, I would like my custom buttons to be greyed out. P.S. Please don't think I am asking you to write my code. Creating these buttons should be very simple, as I have created many before (albeit they were all Ribbon items), and I hope it is okay to ask for some quick assistance on this very specific issue. Thank you in advance!

• WPF Single Selection Across Multiple ItemsControls

  - by gregsdennis

  Part of my app has a month-view calendar interface, but I'm having trouble with item selection. The interface is set up so that each of the days in the view contains a ListBox of items, much like the month view in Outlook. The problem I'm experiencing is that I need to maintain a single item selection across all of the ListBoxes. Below is a sample window that should adequately describe my situation. I need to maintain a single selection between both ListBoxes. <Window x:Class="StackOverflow.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition /> </Grid.ColumnDefinitions> <ListBox ItemsSource="{Binding Numbers}" SelectedItem="{Binding SelectedObject"/> <ListBox Grid.Column="1" ItemsSource="{Binding Dates}" SelectedItem="{Binding SelectedObject"/> </Grid> </Window> In this primitive example, I would expect that when the SelectedObject property of my view model gets set to an item that's not in one ListBox, the selection would be removed in that ListBox, but that doesn't happen. I understand that I can simply name each ListBox, and hook into the SelectionChanged event. I'd prefer to not have to do that with an entire month-view calendar. There has to be a better way. In a previous iteration of the app, I was able to create a SelectionManager static class with an attached property that was used to maintain selection. However, I can't use this now as the classes I'm using for my items are not DependencyObjects, and I'd really prefer not to have to create DependencyObject wrapper classes as this will considerably complicate my architecture. Thanks.

• Loop elements with Jquery and call Omniture s.tl() function to track

  - by ilovewebdev

  Hi, i have a page with a list of items. Each item has a print now link (a.printMe) to print each item. At the end of the list, there's a print all link (a.printAll) to print all items. I want to track number of times an item was printed. If a.printAll link is clicked, then i will send all the item's tracking value to Omniture. I added tracking string into individual item's a.printMe href attribute and track with the following functions: $('a.printMe').click(function() { var value = $(this).attr('href'); track(value); }); $('a.printAll').click(function() { $('a.printMe').each(function() { this.click(); }); // works in IE only. IE 6-8 }); function track(value) { var s = s_gi('account'); s.prop10 = value; s.linkTrackVars = 'prop10'; s.tl(true, 'o'); } The problem is only the last item (in the list) has its value sent to Omniture when i clicked on a.printAll. I finally got the above to work in IE but not Firefox. Anyone encounter this before?

• Stuck in implementing Pagination in Android

  - by user443141

  I am implementing pagination for ListView in Android . I am extending the BaseAdapater class for customising the ListView. Already I have the code working fine for the Customised ListView. Below is the new requirement. 1I am fetching 6 items from server & displaying them . Now when the user scrolls to the 6th item(end of list) , I need to call the server to fetch the next 6 items & update the Listview I have overriden the methods ipublic void onScroll(AbsListView view, int firstVisibleItem,int visibleItemCount, int totalItemCount) iipublic void onScrollStateChanged(AbsListView view, int scrollState) In the first response from the server, I get the total no of pages from the server & for each time I call the server , I get the current page value . Kindly provide me the steps/sample code on how to check the last item of the list & update the list . The code should be iterative since I may need to call multiple times & fetch from server. Warm Regards, CB
