  • ImageView doesn't rescale Image to selected size

    - by Buni
    I'm using a ImageView with a fixed size for adding an icon to a menu. In my application, I use it a lot of times, but on this ImageView the Layout Params seem to not work. Unlike the others ImageViews, in this case, I'm using a template directly, but I think that's not the problem. <?xml version="1.0" encoding="utf-8"?> <ImageView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="1dp" android:layout_height="1dp" android:scaleType="fitCenter" android:src="@drawable/ic_menu_moreoverflow_normal_holo_dark" android:contentDescription="ICON" /> Its been used in code as follows. ImageView iview =(ImageView) View.inflate(context, R.layout.icon, null); Theoretically, It should resize automatically the image, however, the images continues with the original size, although the size was 1dp. Where is the problem? Thanks a lot!

  • Validate Canadian Postal Code Regex

    - by Alex Block
    I have a script written in JavaScript to Validate Canadian Postal Codes using Regex, however it does not seem to be working. Here is the script: If statement: if (myform.zip.value == "" || myform.zip.value == null || myform.zip.value == "Postal Code" || myform.zip.value.length < 12 ) { alert("Please fill in field Postal Code. You should only enter 7 characters"); myform.zip.focus(); return false; } Function: function okNumber(myform) { var regex = /^[ABCEGHJKLMNPRSTVXY]{1}\d{1}[A-Z]{1} *\d{1}[A-Z]{1}\d{1}$/; if (regex.test(myform.zip.value) == false) { alert("Input Valid Postal Code"); myform.zip.focus(); return false; } return true; }

  • ObservableCollection and CollectionChanged Event

    Why does the collectionchanged event not fire in the following code, yet I can see the new instance of InventoryBTO I add to the ObservableCollection? private ObservableCollection<InventoryBTO> _inventoryRecords; public ObservableCollection<InventoryBTO> InventoryRecords { get { return _inventoryRecords; } set { _inventoryRecords = value; } } private InventoryBTO _selectedRecord; public InventoryBTO SelectedRecord { get { return _selectedRecord; } set { if (_selectedRecord != value) { _selectedRecord = value; OnPropertyChanged(new PropertyChangedEventArgs("SelectedRecord")); } } } public InventoryViewModel() { if (_inventoryRecords == null) { InventoryRecords = new ObservableCollection<InventoryBTO>(); this.InventoryRecords.CollectionChanged += new NotifyCollectionChangedEventHandler(InventoryRecords_CollectionChanged); } _inventoryRecords = InventoryListBTO.GetAllInventoryRecords(); } void InventoryRecords_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e) { }

  • How to grab data from webpage in Chrome and output into Chrome extension popup?

    - by chimerical
    For a Google Chrome extension, none of the Javascript I write to manipulate the DOM of the extension popup.html seems to have any effect on the popup's DOM. I can manipulate the DOM of the current webpage in the browser just fine by using content_script.js, and I'm interested in grabbing data from the webpage and outputting it into the extension popup, like so (below: popup.html): <div id="extensionpopupcontent">Links</div> <a onclick="click()">Some Link</a> <script type="text/javascript"> function click() { chrome.tabs.executeScript(null, {file: "content_script.js"}); document.getElementById("extensionpopupcontent").innerHTML = variableDefinedInContentScript; window.close(); } </script> I tried using chrome.extension.sendRequest from the documentation at http://code.google.com/chrome/extensions/messaging.html, but I'm not sure how to properly use it in my case, specifically the greeting and the response. contentscript.js ================ chrome.extension.sendRequest({greeting: "hello"}, function(response) { console.log(response.farewell); });

  • ActionScript Clean Up

    - by TheDarkIn1978
    i want to deallocate a spriteClass from memory and remove it from the display list. when the spriteClass is instantiated, it creates some of it's own sprites with new tweens and tween events and add them as children. i understand that the tween events must be removed in order for the spritClass to become available for garbage collection, and only afterwards should i nullify the spriteClass, but should i also nullify and remove the spriteClass's sprite children and tweens as well, or does it not matter? essentially i'd like to know if by nullifying the spriteClass it automatically removes all of it's added children and new instantiations like tweens, sprites, rects, whatever, or am i responsible for removing them all and otherwise the spriteClass isn't truly null until i do so?

  • T-SQL out of order insert

    - by tearman
    Basically I have a User-Defined Table Type (for use as a table-valued variable) which I'm referencing in a stored procedure that effectively just calls two other stored procedures, then inserts those values into the table type. Id est INSERT INTO @tableValuedVariable (var1, var2, var3, var4, var5) EXEC [dbo].StoredProcedure1; INSERT INTO @tableValuedVariable (var1, var2, var5) EXEC [dbo].StoredProcedure2; You can probably already tell what I'm going to ask. Basically StoredProcedure2 only returns a few of the values the table is set to hold, and I'd like those other variables to just be null (as defined as default). Only SQL is complaining that I'm not specifying all the variables available to that table. The return datasets can be quite sizable so I'd like to avoid loops and such for obvious reasons. Thanks for any help.

  • SQL joins "going up" two tables

    - by blcArmadillo
    I'm trying to create a moderately complex query with joins: SELECT `history`.`id`, `parts`.`type_id`, `serialized_parts`.`serial`, `history_actions`.`action`, `history`.`date_added` FROM `history_actions`, `history` LEFT OUTER JOIN `parts` ON `parts`.`id` = `history`.`part_id` LEFT OUTER JOIN `serialized_parts` ON `serialized_parts`.`parts_id` = `history`.`part_id` WHERE `history_actions`.`id` = `history`.`action_id` AND `history`.`unit_id` = '1' ORDER BY `history`.`id` DESC I'd like to replace `parts`.`type_id` in the SELECT statement with `part_list`.`name` where the relationship I need to enforce between the two tables is `part_list`.`id` = `parts`.`type_id`. Also I have to use joins because in some cases `history`.`part_id` may be NULL which obviously isn't a valid part id. How would I modify the query to do this?

  • SQL for selecting only the last item from a versioned table

    - by Jeremy
    I have a table with the following structure: CREATE TABLE items ( id serial not null, title character varying(255), version_id integer DEFAULT 1, parent_id integer, CONSTRAINT items_pkey PRIMARY KEY (id) ) So the table contains rows that looks as so: id: 1, title: "Version 1", version_id: 1, parent_id: 1 id: 2, title: "Version 2", version_id: 2, parent_id: 1 id: 3, title: "Completely different record", version_id: 1, parent_id: 3 This is the SQL code I've got for selecting out all of the records with the most recent version ids: select * from items inner join ( select parent_id, max(version_id) as version_id from items group by parent_id) as vi on items.version_id = vi.version_id and items.parent_id = vi.parent_id Is there a way to write that SQL statement so that it doesn't use a subselect?

  • Change write-host output color based on foreach if elseif outcome in Powershell

    - by Emo
    I'm trying to change the color of write-host output based on the lastrunoutcome property of SQL Server jobs in Powershell....as in...if a job was successfull, the output of lastrunoutcome is "Success" in green....if failed, then "Failed" in red. I have the script working to get the desired job status...I just don't know how to change the colors. Here's what I have so far: # Check for failed SQL jobs on multiple servers [reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | out-null foreach ($svr in get-content "C:\serverlist2.txt") { $a = get-date $BegDate = (Get-Date $a.AddDays(-1) -f d) + " 12:00:00 AM" $BegDateTrans = [system.datetime]$BegDate write-host $svr $srv=New-Object "Microsoft.SqlServer.Management.Smo.Server" "$svr" $srv.jobserver.jobs | where-object {$_.lastrundate -ge $BegDateTrans -and $_.Name -notlike "????????-????-????-????-????????????"} | format-table name,lastrunoutcome,lastrundate -autosize foreach ($_.lastrunoutcome in $srv.jobserver.jobs) { if ($_.lastrunoutcome = 0) { -forgroundcolor red } else {} } } This seems to be the closest I've gotten...but it's giving me an error of ""LastRunOutcome" is a ReadOnly property." Any help would be greatly appreciated! Thanks! Emo

  • Is POSTing a Dictionary to an .NET MVC action possible?

    - by Brenton Alker
    I have a form which contains a series of fields like: <input type="text" name="User[123]" value="Alice" /> <input type="text" name="User[456]" value="Bob" /> ... Where the index of the User array (123 and 456) are ID's associated with the value. I'm trying to update these values in the controller. My thinking is that a Dictionary that maps ID to name would work, but creating the action like: public void Save(Dictionary<string, string> user) { // ... } results in the user parameter being null. So, is passing a Dictionary possible? or, is there another method to achieve this?

  • c# HTTPListener encoding issue

    - by Rob Griffin
    I have a Java application sending HTTP requests to a C# application. The C# app uses HTTPListener to listen for requests and respond. On the Java side I'm encoding the URL using UTF-8. When I send a \ character it gets encoded as %5C as expected but on the C# side it becomes a / character. The encoding for the request object is Windows-1252 which I think may be causing the problem. How do I set the default encoding to UTF-8? Currently I'm doing this to convert the encoding: foreach (string key in request.QueryString.Keys) { if (key != null) { byte[] sourceBytes =request.ContentEncoding.GetBytes(request.QueryString[key]); string value = Encoding.UTF8.GetString(sourceBytes)); } } This handles the non ASCII characters I'm also sending but doesn't fix the slash problem. Examining request.QueryString[key] in the debugger shows that the / is already there.

  • NHibernate ManyToMany Relationship Cascading AllDeleteOrphan StackOverflowException

    - by Chris
    I have two objects that have a ManyToMany relationship with one another through a mapping table. Though, when I try to save it, I get a stack overflow exception. The following is the code for the mappings: //EventMapping.cs HasManyToMany(x => x.Performers).Table("EventPerformer").Inverse().Cascade.AllDeleteOrphan().LazyLoad().ParentKeyColumn("EventId").ChildKeyColumn("PerformerId"); //PerformerMapping.cs HasManyToMany<Event>(x => x.Events).Table("EventPerformer").Inverse().Cascade.AllDeleteOrphan().LazyLoad().ParentKeyColumn("PerformerId").ChildKeyColumn("EventId"); When I change the performermapping.cs to Cascade.None() I get rid of the exception but then my Event Object doesn't have the performer I associate with it. //In a unit test, paraphrased event.Performers.Add(performer); //Event eventRepository.Save<Event>(event); eventResult = eventRepository.GetById<Event>(event.id); //Event eventResult.Performers[0]; //is null, should have performer in it How should I be writing this properly? Thanks

  • how subsonic SP should return a value

    - by android.sm
    Hi all, I'm very much new to SubSonic and need a little guidance. Here, I want to know how my SP should return a value. Currently, when I execute it I simply pass an Int and it returns me a string value. Here is code: SubSonic SP: public static StoredProcedure GetQuote(int? CategoryId) { StoredProcedure sp = new StoredProcedure("GetQuote", DataService.GetInstance("Quotes Provider"), "dbo"); sp.Command.AddParameter("@CategoryId", CategoryId, DbType.Int32, 0, 10); return sp; } My Code: public bool GetQuote(int category, out string quote) { bool val = false; quote = ""; try { StoredProcedure sp = SPs.GetQuote(category); if (sp != null) { sp.Execute(); val = true; } } catch (Exception err) { throw err; } return val; } Thanks all

  • How return 304 status with FileResult in ASP.NET MVC RC1

    - by Maysam
    As you may know we have got a new ActionResult called FileResult in RC1 version of ASP.NET MVC. Using that, your action methods can return image to browser dynamically. Something like this: public ActionResult DisplayPhoto(int id) { Photo photo = GetPhotoFromDatabase(id); return File(photo.Content, photo.ContentType); } In the HTML code, we can use something like this: <img src="http://mysite.com/controller/DisplayPhoto/657"> Since the image is returned dynamically, we need a way to cache the returned stream so that we don't need to read the image again from database. I guess we can do it with something like this, I'm not sure: Response.StatusCode = 304; This tells the browser that you already have the image in your cache. I just don't know what to return in my action method after setting StatusCode to 304. Should I return null or something?

I believe the error comes fro this line this.stage.loaderInfo since I changed the scope... How I am supposed to fix that?

  • DataTable C# Empty column type

    - by Dested
    I am trying build a DataTable one row at a time using the following code. foreach (var e in Project.ProjectElements[hi.FakeName].Root.Elements()) { index = 0; object[] obj=new object[count]; foreach (var holdingColumn in names) { string d = e.Attribute(holdingColumn.Key).Value; obj[index++] = d; } dt.Rows.Add(obj); } The problem is the DataTable has types tied to the columns. Sometimes im passing null (or an empty string) in that object index and it is telling me that it cant be converted properly to a DateTime (in this case). My question is what should I default this value to, or is there some way to have the DataTable ignore empty values.

  • Javascript cross-domain web request fails with Status=0?

    Yes, I know the following code does not work in IE. I know IE expects me to use XDomainRequest() instead. I don't care about that. This is firefox only.

Does anyone know why? var url = "http://newyork.craigslist.org"; var xdr = new XMLHttpRequest(); //Yes, I know IE expects XDomainRequest.

  • How to determine if an event is already subscribed

    - by Ram
    Hi, In my .NET application I am subscribing to events from another class. The subscription is conditional. I am subscribing to events when the control is visible and de-subscribing it when it become invisible. However in some conditions I do not want to de-subscribe the event even if the control is not visible as I want the result of an operation which is happening on background thread . Is there any way through which I can determine if a that class has already subscribed to that event. I know we can do it in the class which will raise that event by checking event with null but I don not know how to do it in a class which will subscribe to that event.
