  • C# How to download files from FTP Server

    - by user3696888
    I'm trying to download a file (all kinds of files, exe dll txt etc.). And when I try to run it an error comes up on: using (FileStream ws = new FileStream(destination, FileMode.Create)) This is the error message: Access to the path 'C:\Riot Games\League of Legends\RADS\solutions \lol_game_client_sln\releases\0.0.1.41\deploy'(which is my destination, where I want to save it) is denied. Here is my code void download(string url, string destination) { FtpWebRequest request = (FtpWebRequest)WebRequest.Create(url); request.Method = WebRequestMethods.Ftp.DownloadFile; request.Credentials = new NetworkCredential("user", "password"); request.UseBinary = true; using (FtpWebResponse response = (FtpWebResponse)request.GetResponse()) { using (Stream rs = response.GetResponseStream()) { using (FileStream ws = new FileStream(destination, FileMode.Create)) { byte[] buffer = new byte[2048]; int bytesRead = rs.Read(buffer, 0, buffer.Length); while (bytesRead > 0) { ws.Write(buffer, 0, bytesRead); bytesRead = rs.Read(buffer, 0, buffer.Length); } } } }

    - by hudi
    in my wicket application I have 3 checkbox in form: add(new CheckBox("1").setOutputMarkupId(true)); add(new CheckBox("2").setOutputMarkupId(true)); add(new CheckBox("3").setOutputMarkupId(true)); form also contain behavior which unselect checboxes add(new AjaxEventBehavior("onclick") { private static final long serialVersionUID = 1L; @Override protected void onEvent(AjaxRequestTarget target) { List<Component> components = new ArrayList<Component>(); if (target.getLastFocusedElementId() != null) { if (target.getLastFocusedElementId().equals("1")) { components.add(get("2")); components.add(get("3")); } else if (target.getLastFocusedElementId().equals("2")) { components.add(get("1")); } else if (target.getLastFocusedElementId().equals("3")) { components.add(get("1")); } for (Component component : components) { component.setDefaultModelObject(null); target.add(component); } } } }); this works good on mozilla browser but in chrome this doesnt work. How I can improve to work this on chrome too ? UPDATE problem is in: target.getLastFocusedElementId() in mozilla this return what I want but in chrome it always return null but I dont know wh UPDATE 2 google chrome has bug in focus element: http://code.google.com/p/chromium/issues/detail?id=1383&can=1&q=window.focus%20type%3aBug&colspec=ID%20Stars%20Pri%20Area%20Type%20Status%20Summary%20Modified%20Owner so I need to do this in other way

  • Android onClickListener options and help on creating a non-static array adapter

    - by CoderInTraining
    I am trying to make an application that gets data dynamically and displays it in a listView. Here is my code that I have with static data. There are a couple of things I want to try and do and can't figure out how. MainActivity.java package text.example.project; import java.util.ArrayList; import java.util.Arrays; import java.util.Collections; import android.app.ListActivity; import android.os.Bundle; import android.view.View; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.TextView; import android.widget.Toast; public class MainActivity extends ListActivity { //declarations private boolean isItem; private ArrayAdapter<String> item1Adapter; private ArrayAdapter<String> item2Adapter; private ArrayAdapter<String> item3Adapter; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Collections.sort(ITEM1); Collections.sort(ITEM2); Collections.sort(ITEM3); item1Adapter = new ArrayAdapter<String>(this, R.layout.list_item, ITEM1); item2Adapter = new ArrayAdapter<String>(this, R.layout.list_item, ITEM2); item3Adapter = new ArrayAdapter<String>(this, R.layout.list_item, ITEM3); setListAdapter(item1Adapter); isItem = true; ListView lv = getListView(); lv.setTextFilterEnabled(true); lv.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // When clicked, show a toast with the TextView text if (isItem) { //ITEM1.add("another\n\t" + Calendar.getInstance().getTime()); Collections.sort(ITEM1); item2Adapter.notifyDataSetChanged(); setListAdapter(item2Adapter); isItem = false; } else { item1Adapter.notifyDataSetChanged(); setListAdapter(item1Adapter); isItem = true; } Toast.makeText(getApplicationContext(), ((TextView) view).getText(), Toast.LENGTH_SHORT).show(); } }); } // need to turn dynamic static ArrayList<String> ITEM1 = new ArrayList<String> (Arrays.asList( "ITEM1-1", "ITEM1-2" )); static ArrayList<String> ITEM2 = new ArrayList<String> (Arrays.asList( "ITEM2-1", "ITEM2-2" )); static ArrayList<String> ITEM3 = new ArrayList<String> (Arrays.asList("ITEM3-1", "ITEM3-2")); } list_item.xml <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:textSize="16sp" > </TextView> What I want to do is first pull from a dynamic source. I need to do what is almost exactly like this tutorial... http://androiddevelopement.blogspot.in/2011/06/android-xml-parsing-tutorial-using.html ... however, I can't get the tutorial to work... I also would like to know how I can make the list item clicks so that if I click on "ITEM1-1" it goes to the menu "ITEM2-1" and "ITEM2-2". and if "ITEM1-2" is clicked, then it goes to the menu with "ITEM3-1" and "ITEM3-2"... I am totally a noob at this whole android development thing. So any suggestions would be great!

  • Which is more efficient/faster when calling a cached image?

    - by andufo
    Hi, i made an image resizer in php. When an image is resized, it caches a new jpg file with the new dimensions. Next time you call the exact img.php?file=hello.jpg&size=400 it checks if the new jpg has already been created. If it has NOT been created yet, it creates the file and then prints the output (cool). If it ALREADY exists, no new file needs to be generated and instead, it just calls the already cached file. My question is regarding the second scenario. Which of these is faster? redirecting: header('Location: cache/hello_400.jpg');die(); grabbing data and printing the cached file: $data = file_get_contents('cache/hello_400.jpg'); header('Content-type: '.$mime); header('Content-Length: '.strlen($data)); echo $data; Any other ways to improve this?

  • Updating Textures on Runtime in OpenSceneGraph

    - by Abhishek Bansal
    I am working on a project in which i am required to capture frames from external device video and render them on openSceneGraph Node. I am also using GLSL shaders. But i dont know how to update textures on runtime. For other uniforms we need to make callbacks but do we also need to make callbacks for samplers in glsl and openSceneGraph ? My code looks like this. All i am getting right now is a black window. osg::ref_ptr<osg::Geometry> pictureQuad = osg::createTexturedQuadGeometry(osg::Vec3(0.0f,0.0f,0.0f), osg::Vec3(_deviceNameToImageFrameMap[deviceName].frame->s(),0.0f,0.0f), osg::Vec3(0.0f,0.0f,_deviceNameToImageFrameMap[deviceName].frame->t()), 0.0f, 1.0f,_deviceNameToImageFrameMap[deviceName].frame->s(), _deviceNameToImageFrameMap[deviceName].frame->t()); //creating texture and setting up parameters for video frame osg::ref_ptr<osg::TextureRectangle> myTex= new osg::TextureRectangle(_deviceNameToImageFrameMap[deviceName].frame.get()); myTex->setFilter(osg::Texture::MIN_FILTER,osg::Texture::LINEAR); myTex->setFilter(osg::Texture::MAG_FILTER,osg::Texture::LINEAR); myTex->setWrap(osg::Texture::WRAP_S, osg::Texture::CLAMP_TO_EDGE); myTex->setWrap(osg::Texture::WRAP_T, osg::Texture::CLAMP_TO_EDGE); _videoSourceNameToNodeMap[sourceName].geode = new osg::Geode(); _videoSourceNameToNodeMap[sourceName].geode->setDataVariance(osg::Object::DYNAMIC); _videoSourceNameToNodeMap[sourceName].geode->addDrawable(pictureQuad.get()); //apply texture to node _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->setTextureAttributeAndModes(0, myTex.get(), osg::StateAttribute::ON); _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->setMode(GL_DEPTH_TEST, osg::StateAttribute::OFF); _videoSourceNameToNodeMap[sourceName].geode->setDataVariance(osg::Object::DYNAMIC); //Set uniform sampler osg::Uniform* srcFrame = new osg::Uniform( osg::Uniform::SAMPLER_2D, "srcFrame" ); srcFrame->set(0); //Set Uniform Alpha osg::Uniform* alpha = new osg::Uniform( osg::Uniform::FLOAT, "alpha" ); alpha->set(.5f); alpha->setUpdateCallback(new ExampleCallback()); //Enable blending _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->setMode( GL_BLEND, osg::StateAttribute::ON); //Adding blend function to node osg::BlendFunc *bf = new osg::BlendFunc(); bf->setFunction(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->setAttributeAndModes(bf); //apply shader to quad _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->setAttributeAndModes(program, osg::StateAttribute::ON); //add Uniform to shader _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->addUniform( srcFrame ); _videoSourceNameToNodeMap[sourceName].geode->getOrCreateStateSet()->addUniform( alpha );

  • Comet with multiple channels

    - by mark_dj
    Hello, I am writing an web app which needs to subscribe to multiple channels via javascript. I am using Atmosphere and Jersey as backend. However the jQuery plugin they work with only supports 1 channel. I've start buidling my own implementation. Now it works oke, but when i try to subscribe to 2 channels only 1 channel gets notified. Is the XMLHttpRequest blocking the rest of the XMLHttpRequests? Here's my code: function AtmosphereComet(url) { this.Connected = new signals.Signal(); this.Disconnected = new signals.Signal(); this.NewMessage = new signals.Signal(); var xhr = null; var self = this; var gotWelcomeMessage = false; var readPosition; var url = url; var onIncomingXhr = function() { if (xhr.readyState == 3) { if (xhr.status==200) // Received a message { var message = xhr.responseText; console.log(message); if(!gotWelcomeMessage && message.indexOf("") -1) { gotWelcomeMessage = true; self.Connected.dispatch(sprintf("Connected to %s", url)); } else { self.NewMessage.dispatch(message.substr(readPosition)); } readPosition = this.responseText.length; } } else if (this.readyState == 4) { self.disconnect(); } } var getXhr = function() { if ( window.location.protocol !== "file:" ) { try { return new window.XMLHttpRequest(); } catch(xhrError) {} } try { return new window.ActiveXObject("Microsoft.XMLHTTP"); } catch(activeError) {} } this.connect = function() { xhr = getXhr(); xhr.onreadystatechange = onIncomingXhr; xhr.open("GET", url, true); xhr.send(null); } this.disconnect = function() { xhr.onreadystatechange = null; xhr.abort(); } this.send = function(message) { } } And the test code: var connection1 = AtmosphereConnection("http://192.168.1.145:9999/botenveiling/b/product/status/2", AtmosphereComet); var connection2 = AtmosphereConnection("http://192.168.1.145:9999/botenveiling/b/product/status/1", AtmosphereComet); var output = function(msg) { alert(output); }; connection1.NewMessage.add(output); connection2.NewMessage.add(output); connection1.connect(); In AtmosphereConnection I instantiate the given AtmosphereComet with "new". I iterate over the object to check if it has to methods: "send", "connect", "disconnect". The reason for this is that i can switch the implementation later on when i complete the websocket implementation :) However I think the problem rests with the XmlHttpRequest object, or am i mistaken? P.S.: signals.Signal is a js observer/notifier library: http://millermedeiros.github.com/js-signals/ Testing: Firefox 3.6.1.3

  • EditText items in a scrolling list lose their changes when scrolled off the screen

    - by ianww
    I have a long scrolling list of EditText items created by a SimpleCursorAdapter and prepopulated with values from an SQLite database. I make this by: cursor = db.rawQuery("SELECT _id, criterion, localweight, globalweight FROM " + dbTableName + " ORDER BY criterion", null); startManagingCursor(cursor); mAdapter = new SimpleCursorAdapter(this, R.layout.weight_edit_items, cursor, new String[]{"criterion","localweight","globalweight"}, new int[]{R.id.criterion_edit, R.id.localweight_edit, R.id.globalweight_edit}); this.setListAdapter(mAdapter); The scrolling list is several emulator screens long. The items display OK - scrolling through them shows that each has the correct value from the database. I can make an edit change to any of the EditTexts and the new text is accepted and displayed in the box. But...if I then scroll the list far enough to take the edited item off the screen, when I scroll back to look at it again its value has returned to what it was before I made the changes, ie. my edits have been lost. In trying to sort this out, I've done a getText to look at what's in the EditText after I've done my edits (and before a scroll) and getText returns the original text, even though the EditText is displaying my new text. It seems that the EditText has only accepted my edits superficially and they haven't been bound to the EditText, meaning they get dropped when scrolled off the screen. Can anyone please tell me what's going on here and what I need to do to force the EditText to retain its edits? Thanks Ian

  • Unable to read data from the transport connection: the connection was closed

    - by webdreamer
    The exception is Remoting Exception - Authentication Failure. The detailed message says "Unable to read data from the transport connection: the connection was closed." I'm having trouble with creating two simple servers that can comunicate as remote objects in C#. ServerInfo is just a class I created that holds the IP and Port and can give back the address. It works fine, as I used it before, and I've debugged it. Also the server is starting just fine, no exception is thrown, and the channel is registered without problems. I'm using Forms to do the interfaces, and call some of the methods on the server, but didn't find any problems in passing the parameters from the FormsApplication to the server when debugging. All seems fine in that chapter. public ChordServerProgram() { RemotingServices.Marshal(this, "PADIBook"); nodeInt = 0; } public void startServer() { try { serverChannel = new TcpChannel(serverInfo.Port); ChannelServices.RegisterChannel(serverChannel, true); } catch (Exception e) { Console.WriteLine(e.ToString()); } } I run two instances of this program. Then startNode is called on one of the instances of the application. The port is fine, the address generated is fine as well. As you can see, I'm using the IP for localhost, since this server is just for testing purposes. public void startNode(String portStr) { IPAddress address = IPAddress.Parse("127.0.0.1"); Int32 port = Int32.Parse(portStr); serverInfo = new ServerInfo(address, port); startServer(); //node = new ChordNode(serverInfo,this); } Then, in the other istance, through the interface again, I call another startNode method, giving it a seed server to get information from. This is where it goes wrong. When it calls the method on the seedServer proxy it just got, a RemotingException is thrown, due to an authentication failure. (The parameter I'll want to get is the node, I'm just using the int to make sure the ChordNode class has nothing to do with this error.) public void startNode(String portStr, String seedStr) { IPAddress address = IPAddress.Parse("127.0.0.1"); Int32 port = Int32.Parse(portStr); serverInfo = new ServerInfo(address, port); IPAddress addressSeed = IPAddress.Parse("127.0.0.1"); Int32 portSeed = Int32.Parse(seedStr); ServerInfo seedInfo = new ServerInfo(addressSeed, portSeed); startServer(); ChordServerProgram seedServer = (ChordServerProgram)Activator.GetObject(typeof(ChordServerProgram), seedInfo.GetFullAddress()); // node = new ChordNode(serverInfo,this); int seedNode = seedServer.nodeInt; // node.chordJoin(seedNode.self); }

  • Problems with mod_rewrite and 301 redirects from one dynamic url to another

    - by user349891
    Hey all, I'm having all kinds of problems with a bunch of apache redirects just now and could really use some help! I'm wating to put in a 301 redirect for a load of urls from a client's old site to their new site in the following format; Old - page.php?pageNum_rs_all=0&totalRows_rs_all=112 New - page/sub?foo=bar The values in the query sting for the old site don't in any way tie up to any ids or references on the new site, I only want to match that specific request and redirect to the new page. It feels like I've tried just about every combination of rewriterule I can find online but still nothing seems to be working. This is running on Apache 2.2. The rule I started with (and keep going back to) is; RewriteRule ^/page.php\?pageNum_rs_all=0&totalRows_rs_all=112 /page/sub?foo=bar [R=301,L,NE] Any help would be greatly appreciated! c.

  • How to Get Dictionary<int, string> from Linq to XML Anonymous Object?

    - by DaveDev
    Currently I'm getting a list of HeaderColumns from the following XML snippet: <HeaderColumns> <column performanceId="12" text="Over last month %" /> <column performanceId="13" text="Over last 3 months %" /> <column performanceId="16" text="1 Year %" /> <column performanceId="18" text="3 Years % p.a." /> <column performanceId="20" text="5 Years % p.a." /> <column performanceId="22" text="10 Years % p.a." /> </HeaderColumns> from which I create an object as follows: (admitedly similar to an earlier question!) var performancePanels = new { Panels = (from panel in doc.Elements("PerformancePanel") select new { HeaderColumns = (from column in panel.Elements("HeaderColumns").Elements("column") select new { PerformanceId = (int)column.Attribute("performanceId"), Text = (string)column.Attribute("text") }).ToList(), }).ToList() }; I'd like if HeaderColumns was a Dictionary() so later I extract the values from the anonymous object like follows: Dictionary<int, string> myHeaders = new Dictionary<int, string>(); foreach (var column in performancePanels.Panels[0].HeaderColumns) { myHeaders.Add(column.PerformanceId, column.Text); } I thought I could achieve this with the Linq to XML with something similar to this HeaderColumns = (from column in panel.Elements("HeaderColumns").Elements("column") select new Dictionary<int, string>() { (int)column.Attribute("performanceId"), (string)column.Attribute("text") }).ToDictionary<int,string>(), but this doesn't work because ToDictionary() needs a Func parameter and I don't know what that is / how to implement it, and the code's probably wrong anyway! Could somebody please suggest how I can achieve the result I need? Thanks.

  • object construct a class of objects in java

    - by Mgccl
    There is a super class, A, and there are many subclasses, B,C,D... people can write more subclasses. Each of the class have the method dostuff(), each is different in some way. I want an object that constructs any object that belong to A or any of it's subclass. For example I can pass the name of the subclass, or a object of that class, and it will construct another object of the class. Of course I can write A construct(A var){ stuff = var.dostuff(); domorestuff(stuff) return new A(stuff); } B construct(B var){ stuff = var.dostuff(); domorestuff(stuff) return new B(stuff); } C construct(C var){ stuff = var.dostuff(); domorestuff(stuff) return new C(stuff); } but this is not efficient. I have to write a few new lines every time I make a new subclass. It seems I can't use generics either. Because I can't use dostuff() on objects not in any of the subclass of A. What should I do in this situation?

  • How to proceed jpeg Image file size after read--rotate-write operations in Java?

    - by zamska
    Im trying to read a JPEG image as BufferedImage, rotate and save it as another jpeg image from file system. But there is a problem : after these operations I cannot proceed same file size. Here the code //read Image BufferedImage img = ImageIO.read(new File(path)); //rotate Image BufferedImage rotatedImage = new BufferedImage(image.getHeight(), image.getWidth(), BufferedImage.TYPE_3BYTE_BGR); Graphics2D g2d = (Graphics2D) rotatedImage.getGraphics(); g2d.rotate(Math.toRadians(PhotoConstants.ROTATE_LEFT)); int height=-rotatedImage.getHeight(null); g2d.drawImage(image, height, 0, null); g2d.dispose(); //Write Image Iterator iter = ImageIO.getImageWritersByFormatName("jpeg"); ImageWriter writer = (ImageWriter)iter.next(); // instantiate an ImageWriteParam object with default compression options ImageWriteParam iwp = writer.getDefaultWriteParam(); try { FileImageOutputStream output = null; iwp.setCompressionMode(ImageWriteParam.MODE_EXPLICIT); iwp.setCompressionQuality(0.98f); // an integer between 0 and 1 // 1 specifies minimum compression and maximum quality File file = new File(path); output = new FileImageOutputStream(file); writer.setOutput(output); IIOImage iioImage = new IIOImage(image, null, null); writer.write(null, iioImage, iwp); output.flush(); output.close(); writer.dispose(); Is it possible to access compressionQuality parameter of original jpeg image in the beginning. when I set 1 to compression quality, the image gets bigger size. Otherwise I set 0.9 or less the image gets smaller size. How can i proceed the image size after these operations? Thank you,

  • Variable scope and the 'using' statement in .NET

    - by pete the pagan-gerbil
    If a variable is at class level (ie, private MyDataAccessClass _dataAccess;, can it be used as part of a using statement within the methods of that class to dispose of it correctly? Is it wise to use this method, or is it better to always declare a new variable with a using statement (ie, using (MyDataAccessClass dataAccess = new MyDataAccessClass()) instead of using (_dataAccess = new MyDataAccessClass()))?

  • How to Refresh / Reload a KML layer in OpenLayers. Dynamic KML Layer.

    - by Ozaki
    TLDR See my answer below on how to refresh the layer. So far I have tried action function as follows: function RefreshKMLData(layer) { layer.loaded = false; layer.setVisibility(true); layer.redraw({ force: true }); } set interval of the function: window.setInterval(RefreshKMLData, 5000, KMLLAYER); the layer itself: var KMLLAYER = new OpenLayers.Layer.Vector("MYKMLLAYER", { projection: new OpenLayers.Projection("EPSG:4326"), strategies: [new OpenLayers.Strategy.Fixed()], protocol: new OpenLayers.Protocol.HTTP({ url: MYKMLURL, format: new OpenLayers.Format.KML({ extractStyles: true, extractAttributes: true }) }) }); the url for KMLLAYER with Math random so it doesnt cache: var MYKMLURL = var currentanchorpositionurl = 'http://' + host + '/data?_salt=' + Math.random(); I would have thought that this would Refresh the layer. As by setting its loaded to false unloads it. Visibility to true reloads it and with the Math random shouldn't allow it to cache? So has anyone done this before or know how I can get this to work? TLDR See my answer below on how to refresh the layer.

  • how to call the method in thread with aruguments and return some value

    - by ratty
    i like to call the method in thread with aruguments and return some value here example class Program { static void Main() { Stopwatch stop = new Stopwatch(); stop.Start(); Thread FirstThread = new Thread(new ThreadStart(Fun1)); Thread SecondThread = new Thread(new ThreadStart(Fun2)); FirstThread.Start(); SecondThread.Start(); } public static void Fun1() { for (int i = 1; i <= 1000; i++) { Console.WriteLine("Fun1 writes:{0}", i); } } public static void Fun2() { for (int i = 1000; i >= 6; i--) { Console.WriteLine("Fun2 writes:{0}", i); } } } i know this above example run successfully but if method fun1 like this public int fun1(int i) { for (int n = i; n >= i+10; n++) { Console.WriteLine("Fun2 writes:{0}", i); } } then how can i call this in thread. Is it possible .Any body Help for me

  • non contiguous String object C#.net

    - by Kazoom
    By what i understand String and StringBuilder objects both allocate contiguous memory underneath. My program runs for days buffering several output in a String object. This sometimes cause outofmemoryexception which i think is because of non availability of contiguous memory. my string size can go upto 100MBs and i m concatenating new string frequently this causes new string object being allocated. i can reduce new string object creation by using Stringbuilder but that would not solve my problem entirely Is there an alternative to a contiguous string object?

  • Why this java application print "true"?

    - by user292084
    This is my first Class Hello.java public class Hello { String name = ""; } This is my second Class Test1.java public class Test1 { public static void main(String[] args) { Hello h = new Hello(); Test1 t = new Test1(); t.build(h); System.out.println((h.name)); } void build(Hello h){ h.name = "me"; } } When I run Test1.java, it prints "me". I think I understand, because of "reference transfer". This is my third Class Test2.java public class Test2 { public static void main(String[] args) { Hello h = null; Test2 t = new Test2(); t.build(h); System.out.println(((h == null))); } void build(Hello h){ h = new Hello(); } } When I run Test2.java, it prints "true", why ? Is it "reference transfer" no longer? I am confused.

  • Custom View Engine in ASP.NET MVC 2 does not work with Areas

    - by mare
    I used the code below so far with ASP.NET MVC v1 and v2 but when I added an Area today to my application, the controller for the area couldn't find any views in my Areas/Views/controllerView folder. It issued the very well known exception that it searched those 4 standard folders but it did not look under Areas.. How can I change the code so that it will work with Areas? Maybe an example of custom view engine under ASP.NET MVC 2 with Areas support? The information about it on the net is very scarse.. Here's the code: public class PendingViewEngine : VirtualPathProviderViewEngine { public PendingViewEngine() { // This is where we tell MVC where to look for our files. /* {0} = view name or master page name * {1} = controller name */ MasterLocationFormats = new[] {"~/Views/Shared/{0}.master", "~/Views/{0}.master"}; ViewLocationFormats = new[] { "~/Views/{1}/{0}.aspx", "~/Views/Shared/{0}.aspx", "~/Views/Shared/{0}.ascx", "~/Views/{1}/{0}.ascx" }; PartialViewLocationFormats = new[] {"~/Views/{1}/{0}.ascx", "~/Views/Shared/{0}.ascx"}; } protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath) { return new WebFormView(partialPath, ""); } protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath) { return new WebFormView(viewPath, masterPath); } }
