  • ValidationProperty not returning entered value for textbox

    - by nat
    hi I have a custom control, (relevant code at the bottom) it consists of some text/links and a hidden textbox (rather than a hidden input). when rendered, the user via another dialog and some JS sets the value of the textbox to an integer and clicks submit on the form. i am trying to assure that the user has entered a number (via the JS) and that the textbox is not still set to its default of "0" the requiredfieldvalidator works just fine, if i dont change the value it spots it on the client and fills the validation summary on the page with the appropriate message. unfortunately when i do fill the textbox, the validator also rejests the post as the controls textbox text value is still set to "0", even though on the form it has changed. clearly i am doing something wrong.. but cant work out what it is? could someone enlighten me please, this is driving me potty if i step through the code, when the get of the mediaidtext is hit,the findcontrol finds the textbox, but the value is still set to "0" many thanks code below nat [ValidationProperty("MediaIdText")] public class MediaLibraryFileControl: CompositeControl { private int mediaId = 0; public int MediaId { get { return mediaId; } set { mediaId = value; } } public string MediaIdText { get { string txt = "0"; Control ctrl = this.FindControl(this.UniqueID+ "_hidden"); try { txt = ((TextBox)ctrl).Text; MediaId = Convert.ToInt32(txt); } catch { MediaId = 0; } return txt; } } protected override void CreateChildControls() { this.Controls.Add(new LiteralControl("<span>")); this.Controls.Add(new LiteralControl("<span id=\"" + TextControlName + "\">" + getMediaDetails() + "</span>")); TextBox tb = new TextBox(); tb.Text = this.MediaId.ToString(); tb.ID = this.UniqueID + "_hidden"; tb.CssClass = "hidden"; this.Controls.Add(tb); if (Select == true) { this.Controls.Add(new LiteralControl(string.Format("&nbsp;[<a href=\"javascript:{0}(this,'{1}','{2}')\" class=\"select\">{3}</a>]", dialog, this.UniqueID, this.categoryId, "select"))); this.Controls.Add(new LiteralControl(string.Format("&nbsp;[<a href=\"javascript:{0}(this,'{1}')\" class=\"select\">{2}</a>]", clearDialog, this.ID, "clear"))); } this.Controls.Add(new LiteralControl("</span>")); } protected virtual string getMediaDetails() { //... return String.Empty; } } this is the code adding the validationcontrol the editcontrol is the instance of the control above public override Control RenderValidationControl(Control editControl) { Control ctrl = new PlaceHolder(); RequiredFieldValidator req = new RequiredFieldValidator(); req.ID = editControl.ClientID + "_validator"; req.ControlToValidate = editControl.ID; req.Display = ValidatorDisplay.None; req.InitialValue = "0"; req.EnableClientScript = false; req.ErrorMessage = "control cannot be blank"; ctrl.Controls.Add(req); return ctrl; }

  • Servlet response wrapper has encoding problem

    - by John O
    A servlet response wrapper is being used in a Servlet Filter. The idea is that the response is manipulated, with a 'nonce' value being injected into forms, as part of defence against CSRF attacks. The web app is using UTF-8 everywhere. When the Servlet Filter is absent, no problems. When the filter is added, encoding issues occur. (It seems as if the response is reverting to 8859-1.) The guts of the code : final class CsrfResponseWrapper extends AbstractResponseWrapper { ... byte[] modifyResponse(byte[] aInputResponse){ ... String originalInput = new String(aInputResponse, encoding); String modifiedResult = addHiddenParamToPostedForms(originalInput); result = modifiedResult.getBytes(encoding); ... } ... } As I understand it, the transition between byte-land and String-land should specify an encoding. That is done here, as you can see, in two places. The value of the 'encoding' variable is 'UTF-8'; the alteration of the String itself is standard string manipulation (with a regex), and never specifies an encoding (addHiddenParamToPostedForms). Where am I in error about the encoding? EDIT: Here is the base class (sorry it's rather long): package hirondelle.web4j.security; import javax.servlet.ServletOutputStream; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpServletResponseWrapper; import java.io.ByteArrayOutputStream; import java.io.IOException; import java.io.PrintWriter; /** Abstract Base Class for altering response content.

  • How to manipulate data after its retrieved via remote database

    - by bMon
    So I've used code examples from all over the net and got my app to accurately call a .php file on my server, retrieve the JSON data, then parse the data, and print it. The problem is that its just printing to the screen for sake of the tutorial I was following, but now I need to use that data in other places and need help figuring out that process. The ultimate goal is to return my db query with map coordinates, then plot them on a google map. I have another app in which I manually plot points on a map, so I'll be integrating this app with that once I can get my head around how to correctly manipulate the data returned. public class Remote extends Activity { /** Called when the activity is first created. */ TextView txt; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Create a crude view - this should really be set via the layout resources // but since its an example saves declaring them in the XML. LinearLayout rootLayout = new LinearLayout(getApplicationContext()); txt = new TextView(getApplicationContext()); rootLayout.addView(txt); setContentView(rootLayout); // Set the text and call the connect function. txt.setText("Connecting..."); //call the method to run the data retreival txt.setText(getServerData(KEY_121)); } public static final String KEY_121 = "http://example.com/mydbcall.php"; private String getServerData(String returnString) { InputStream is = null; String result = ""; //the year data to send //ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); //nameValuePairs.add(new BasicNameValuePair("year","1970")); try{ HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(KEY_121); HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); is = entity.getContent(); }catch(Exception e){ Log.e("log_tag", "Error in http connection "+e.toString()); } //convert response to string try{ BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } is.close(); result=sb.toString(); }catch(Exception e){ Log.e("log_tag", "Error converting result "+e.toString()); } //parse json data try{ JSONArray jArray = new JSONArray(result); for(int i=0;i<jArray.length();i++){ JSONObject json_data = jArray.getJSONObject(i); Log.i("log_tag","longitude: "+json_data.getDouble("longitude")+ ", latitude: "+json_data.getDouble("latitude") ); //Get an output to the screen returnString += "\n\t" + jArray.getJSONObject(i); } }catch(JSONException e){ Log.e("log_tag", "Error parsing data "+e.toString()); } return returnString; } } So the code: returnString += "\n\t" + jArray.getJSONObject(i); is what is currently printing to the screen. What I have to figure out is how to get the data into something I can reference in other spots in the program, and access the individual elements ie: double longitude = jArray.getJSONObject(3).longitude; or something to that effect.. I figure the class getServerData will have to return a Array type or something? Any help is appreciated, thanks.

  • Logcat error: "addView(View, LayoutParams) is not supported in AdapterView" in a ListView

    - by HacKreatorz
    I'm doing an aplication for Android and something I need is that it shows a list of all files and directories in the SD Card and it has to be able to move through the different directories. I found a good tutorial in anddev: http://bit.ly/h4GyFC I modified a few things so the aplication moves in the SD Card and not in Android root Directories but the rest is mostly the same. This is my xml file for the activity: <?xml version="1.0" encoding="utf-8"?> <ListView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@id/android:list" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" /> </ListView> And this is the code for the Activity: import hackreatorz.cifrador.R; import java.io.File; import java.util.ArrayList; import android.app.ListActivity; import android.content.res.Configuration; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.Toast; public class ArchivosSD extends ListActivity { private ArrayList<String> directoryEntries = new ArrayList<String>(); private File currentDirectory = new File("/sdcard/"); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); browseToSD(); } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); } private void browseToSD() { browseTo(new File("/sdcard/")); } private void upOneLevel() { if(this.currentDirectory.getParent() != null) this.browseTo(this.currentDirectory.getParentFile()); } private void browseTo(final File directory) { if (directory.isDirectory()) { this.currentDirectory = directory; fill(directory.listFiles()); } else { Toast.makeText(ArchivosSD.this, this.directoryEntries.get(this.getSelectedItemPosition()), Toast.LENGTH_SHORT).show(); } } private void fill(File[] files) { this.directoryEntries.clear(); this.directoryEntries.add(getString(R.string.current_dir)); if(this.currentDirectory.getParent() != null) this.directoryEntries.add(getString(R.string.up_one_level)); int currentPathStringLength = (int) this.currentDirectory.getAbsoluteFile().length(); for (File file : files) { this.directoryEntries.add(file.getAbsolutePath().substring(currentPathStringLength)); } setListAdapter(new ArrayAdapter<String>(this, R.layout.archivos_sd, this.directoryEntries)); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { int selectionRowID = (int) this.getSelectedItemPosition(); String selectedFileString = this.directoryEntries.get(selectionRowID); if (selectedFileString.equals(".")) { this.browseToSD(); } else if(selectedFileString.equals("..")) { this.upOneLevel(); } else { File clickedFile = null; clickedFile = new File(this.currentDirectory.getAbsolutePath() + this.directoryEntries.get(selectionRowID)); if(clickedFile != null) this.browseTo(clickedFile); } } } I don't get any errores in Eclipse, but I get a Force Close when running the aplication on my phone and when I look at Logcat I see the following: 01-01 23:30:29.858: ERROR/AndroidRuntime(14911): FATAL EXCEPTION: main *01-01 23:30:29.858: ERROR/AndroidRuntime(14911): java.lang.UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView* I don't have a clue what to do, I've looked up in Google and I didn't find anything and I did the same at stackoverflow. This is my first aplication in Java and for Android so I'm a real n00b and if the answer was there, I didn't understand it so I would really apreciate if you could explain what I should do to fix this error and why. Thanks for everything in advanced.

  • C# ambiguity in Func + extension methods + lambdas

    - by Hobbes
    I've been trying to make my way through this article: http://blogs.msdn.com/wesdyer/archive/2008/01/11/the-marvels-of-monads.aspx ... And something on page 1 made me uncomfortable. In particular, I was trying to wrap my head around the Compose<() function, and I wrote an example for myself. Consider the following two Func's: Func<double, double> addTenth = x => x + 0.10; Func<double, string> toPercentString = x => (x * 100.0).ToString() + "%"; No problem! It's easy to understand what these two do. Now, following the example from the article, you can write a generic extension method to compose these functions, like so: public static class ExtensionMethods { public static Func<TInput, TLastOutput> Compose<TInput, TFirstOutput, TLastOutput>( this Func<TFirstOutput, TLastOutput> toPercentString, Func<TInput, TFirstOutput> addTenth) { return input => toPercentString(addTenth(input)); } } Fine. So now you can say: string x = toPercentString.Compose<double, double, string>(addTenth)(0.4); And you get the string "50%" So far, so good. But there's something ambiguous here. Let's say you write another extension method, so now you have two functions: public static class ExtensionMethods { public static Func<TInput, TLastOutput> Compose<TInput, TFirstOutput, TLastOutput>( this Func<TFirstOutput, TLastOutput> toPercentString, Func<TInput, TFirstOutput> addTenth) { return input => toPercentString(addTenth(input)); } public static Func<double, string> Compose<TInput, TFirstOutput, TLastOutput>(this Func<double, string> toPercentString, Func<double, double> addTenth) { return input => toPercentString(addTenth(input + 99999)); } } Herein is the ambiguity. Don't these two function have overlapping signatures? Yes. Does this even compile? Yes. Which one get's called? The second one (which clearly gives you the "wrong" result) gets called. If you comment out either function, it still compiles, but you get different results. It seems like nitpicking, but there's something that deeply offends my sensibilities here, and I can't put my finger on it. Does it have to do with extension methods? Does it have to do with lambdas? Or does it have to do with how Func< allows you to parameterize the return type? I'm not sure. I'm guessing that this is all addressed somewhere in the spec, but I don't even know what to Google to find this. Help!

  • How to generalize a method call in Java (to avoid code duplication)

    - by dln385
    I have a process that needs to call a method and return its value. However, there are several different methods that this process may need to call, depending on the situation. If I could pass the method and its arguments to the process (like in Python), then this would be no problem. However, I don't know of any way to do this in Java. Here's a concrete example. (This example uses Apache ZooKeeper, but you don't need to know anything about ZooKeeper to understand the example.) The ZooKeeper object has several methods that will fail if the network goes down. In this case, I always want to retry the method. To make this easy, I made a "BetterZooKeeper" class that inherits the ZooKeeper class, and all of its methods automatically retry on failure. This is what the code looked like: public class BetterZooKeeper extends ZooKeeper { private void waitForReconnect() { // logic } @Override public Stat exists(String path, Watcher watcher) { while (true) { try { return super.exists(path, watcher); } catch (KeeperException e) { // We will retry. } waitForReconnect(); } } @Override public byte[] getData(String path, boolean watch, Stat stat) { while (true) { try { return super.getData(path, watch, stat); } catch (KeeperException e) { // We will retry. } waitForReconnect(); } } @Override public void delete(String path, int version) { while (true) { try { super.delete(path, version); return; } catch (KeeperException e) { // We will retry. } waitForReconnect(); } } } (In the actual program there is much more logic and many more methods that I took out of the example for simplicity.) We can see that I'm using the same retry logic, but the arguments, method call, and return type are all different for each of the methods. Here's what I did to eliminate the duplication of code: public class BetterZooKeeper extends ZooKeeper { private void waitForReconnect() { // logic } @Override public Stat exists(final String path, final Watcher watcher) { return new RetryableZooKeeperAction<Stat>() { @Override public Stat action() { return BetterZooKeeper.super.exists(path, watcher); } }.run(); } @Override public byte[] getData(final String path, final boolean watch, final Stat stat) { return new RetryableZooKeeperAction<byte[]>() { @Override public byte[] action() { return BetterZooKeeper.super.getData(path, watch, stat); } }.run(); } @Override public void delete(final String path, final int version) { new RetryableZooKeeperAction<Object>() { @Override public Object action() { BetterZooKeeper.super.delete(path, version); return null; } }.run(); return; } private abstract class RetryableZooKeeperAction<T> { public abstract T action(); public final T run() { while (true) { try { return action(); } catch (KeeperException e) { // We will retry. } waitForReconnect(); } } } } The RetryableZooKeeperAction is parameterized with the return type of the function. The run() method holds the retry logic, and the action() method is a placeholder for whichever ZooKeeper method needs to be run. Each of the public methods of BetterZooKeeper instantiates an anonymous inner class that is a subclass of the RetryableZooKeeperAction inner class, and it overrides the action() method. The local variables are (strangely enough) implicitly passed to the action() method, which is possible because they are final. In the end, this approach does work and it does eliminate the duplication of the retry logic. However, it has two major drawbacks: (1) it creates a new object every time a method is called, and (2) it's ugly and hardly readable. Also I had to workaround the 'delete' method which has a void return value. So, here is my question: is there a better way to do this in Java? This can't be a totally uncommon task, and other languages (like Python) make it easier by allowing methods to be passed. I suspect there might be a way to do this through reflection, but I haven't been able to wrap my head around it.

  • C# : Console.Read() does not get the "right" input

    - by Daemonfire3002nd
    Hi there, I have the following code: The actual problem is the "non-quoted" code. I want to get the player amount (max = 4), but when I ask via Console.Read() and I enter any Int from 1 to 4 I get as value: 48 + Console.Read(). They only thing how I can get the "real" input is using Console.ReadLine(), but this does not give me an Integer, no it returns a string, and actually do not know how to convert String (Numbers) to Integers in C#, because I am new, and because I only found ToString() and not ToNumber. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace eve_calc_tool { class Program { int players; int units; int active_units; int inactive_units; int finished_units; int lastDiceNumber = 0; bool game_state; public static void Main(string[] args) { int count_game = 0; //Console.Title = "Mensch ärger dich nicht"; //Console.WriteLine("\tNeues Spiel wird"); //Console.WriteLine("\t...geladen"); //System.Threading.Thread.Sleep(5000); //Console.Clear(); //Console.WriteLine("Neues Spiel wird gestartet, bitte haben sie etwas Geduld"); //Console.Title = "Spiel " + count_game.ToString(); //Console.Clear(); //string prevText = "Anzahl der Spieler: "; //Console.WriteLine(prevText); string read = Console.ReadLine(); /*Program game = new Program(); game.players = read; game.setPlayers(game.players); if (game.players > 0 && 5 > game.players) { game.firstRound(); }*/ string readagain = read; Console.ReadLine(); } /* bool setPlayers(int amount) { players = amount; if (players > 0) { return true; } else { return false; } } bool createGame() { inactive_units = units = getPlayers() * 4; active_units = 0; finished_units = 0; game_state = true; if (game_state == true) { return true; } else { return false; } } int getPlayers() { return players; } private static readonly Random random = new Random(); private static readonly object syncLock = new object(); public static int RandomNumber(int min, int max) { lock (syncLock) { // synchronize return random.Next(min, max); } } int rollDice() { lastDiceNumber = RandomNumber(1,6); return lastDiceNumber; } int firstRound() { int[] results = new int[getPlayers()]; for (int i = 0; i < getPlayers(); i++) { results[i] = rollDice(); } Array.Sort(results); return results[3]; } */ } }

    in my search form, if the user types 'good', it displays all the results which contain the keyword 'good'. however if the user types in 'good sweetest', it displays no results because there is no record with the two words appearing together; BUT appearing in an entry at different places. for example, the record says: A good action is an ever-remaining store and a pure yield the user types in 'good', it will show up this record, but if the user types in 'good' + 'pure', it will not show anything. or if the record contains the keyword 'good-deeds' and if the user types in 'good deeds' without the hyphen, it will not show anything. what i would like is that if the user types in 'good' + 'pure' or 'good deeds' it should records containing these keywords highlighting them. search.php code: $search_result = ""; $search_result = $_POST["q"]; $search_result = trim($search_result); //Check if the string is empty if ($search_result == "") { echo "<p class='error'>Search Error.

  • QUiLoader and ignored dynamic properties

    - by Googie
    I'm loading the .ui file, where one of the widgets (QComboBox) has a dynamic property (http://qt-project.org/doc/qt-5/properties.html#dynamic-properties). The UI file looks like this: <?xml version="1.0" encoding="UTF-8"?> <ui version="4.0"> <class>PopulateScriptConfig</class> <widget class="QWidget" name="PopulateScriptConfig"> <property name="geometry"> <rect> <x>0</x> <y>0</y> <width>400</width> <height>300</height> </rect> </property> <property name="windowTitle"> <string>Form</string> </property> <layout class="QVBoxLayout" name="verticalLayout"> <item> <widget class="QGroupBox" name="langGroup"> <property name="title"> <string>Language</string> </property> <layout class="QVBoxLayout" name="verticalLayout_3"> <item> <widget class="QComboBox" name="langCombo"> <property name="ScriptingLangCombo" stdset="0"> <bool>true</bool> </property> </widget> </item> </layout> </widget> </item> <item> <widget class="QGroupBox" name="codeGroup"> <property name="title"> <string>Implementation</string> </property> <layout class="QVBoxLayout" name="verticalLayout_2"> <item> <widget class="QPlainTextEdit" name="codeEdit"/> </item> </layout> </widget> </item> </layout> </widget> <resources/> <connections/> </ui> The important part is: <widget class="QComboBox" name="langCombo"> <property name="ScriptingLangCombo" stdset="0"> <bool>true</bool> </property> </widget> I'm loading the file with QUiLoader::load(). Note, that I have extended the QUiLoader class, but only to access createWidget() method, where I can query each widget like this: QWidget* UiLoader::createWidget(const QString& className, QWidget* parent, const QString& name) { QWidget* w = QUiLoader::createWidget(className, parent, name); qDebug() << w->dynamicPropertyNames(); return w; } As a result I see empty list displayed, so it seems like the dynamic property is completly ignored. Any ideas? P.S. I've made sure that I load correct file. 3 times.

  • Java: Object Array assignment in for loop

    - by Hackster
    I am trying to use Dijkstra's algorithm to find the shortest path from a specific vertex (v0) to the rest of them. That is solved and works well with this code from this link below: http://en.literateprograms.org/index.php?title=Special:DownloadCode/Dijkstra%27s_algorithm_(Java)&oldid=15444 I am having trouble with assigning the Edge array in a for loop from the user input, as opposed to hard-coding it like it is here. Any help assigning a new edge to Edge[] adjacencies from each vertex? Keeping in mind it could be 1 or multiple edges. class Vertex implements Comparable<Vertex> { public final String name; public Edge[] adjacencies; public double minDistance = Double.POSITIVE_INFINITY; public Vertex previous; public Vertex(String argName) { name = argName; } public String toString() { return name; } public int compareTo(Vertex other){ return Double.compare(minDistance, other.minDistance); } } class Edge{ public final Vertex target; public final double weight; public Edge(Vertex argTarget, double argWeight){ target = argTarget; weight = argWeight; } } public static void main(String[] args) { Vertex v[] = new Vertex[3]; Vertex v[0] = new Vertex("Harrisburg"); Vertex v[1] = new Vertex("Baltimore"); Vertex v[2] = new Vertex("Washington"); v0.adjacencies = new Edge[]{ new Edge(v[1], 1), new Edge(v[2], 3) }; v1.adjacencies = new Edge[]{ new Edge(v[0], 1), new Edge(v[2], 1),}; v2.adjacencies = new Edge[]{ new Edge(v[0], 3), new Edge(v[1], 1) }; Vertex[] vertices = { v0, v1, v2}; /*Three vertices with weight: V0 connects (V1,1),(V2,3) V1 connects (V0,1),(V2,1) V2 connects (V1,1),(V2,3) */ computePaths(v0); for (Vertex v : vertices){ System.out.println("Distance to " + v + ": " + v.minDistance); List<Vertex> path = getShortestPathTo(v); System.out.println("Path: " + path); } } } The above code works well in finding the shortest path from v0 to all the other vertices. The problem occurs when assigning the new edge[] to edge[] adjacencies. For example this does not produce the correct output: for (int i = 0; i < total_vertices; i++){ s = br.readLine(); char[] line = s.toCharArray(); for (int j = 0; j < line.length; j++){ if(j % 4 == 0 ){ //Input: vertex weight vertex weight: 1 1 2 3 int vert = Integer.parseInt(String.valueOf(line[j])); int w = Integer.parseInt(String.valueOf(line[j+2])); v[i].adjacencies = new Edge[] {new Edge(v[vert], w)}; } } } As opposed to this: v0.adjacencies = new Edge[]{ new Edge(v[1], 1), new Edge(v[2], 3) }; How can I take the user input and make an Edge[], to pass it to adjacencies? The problem is it could be 0 edges or many. Any help would be much appreciated Thanks!

  • HTTP client - HTTP 405 error "Method not allowed". I send a HTTP Post but for some reason HTTP Get i

    - by Shino88
    Hey I am using apache library. I have created a class which sends a post request to a servlet. I have set up the parameters for the client and i have created a HTTP post object to be sent but for some reason when i excute the request i get a reposnse that says the get method is not supported(which is true cause i have only made a dopost method in my servlet). It seems that a get request is being sent but i dont know why. The post method worked before but i started gettng http error 417 "Expectation Failed" which i fixed by adding paramenters. below is my class with the post method. P.s i am developing for android. public class HTTPrequestHelper { private final ResponseHandler<String> responseHandler; private static final String CLASSTAG = HTTPrequestHelper.class.getSimpleName(); private static final DefaultHttpClient client; static{ HttpParams params = new BasicHttpParams(); params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); params.setParameter(CoreProtocolPNames.HTTP_CONTENT_CHARSET, HTTP.UTF_8); ///params.setParameter(CoreProtocolPNames.USER_AGENT, "Android-x"); params.setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 15000); params.setParameter(CoreConnectionPNames.STALE_CONNECTION_CHECK, false); SchemeRegistry schemeRegistry = new SchemeRegistry(); schemeRegistry.register( new Scheme("http", PlainSocketFactory.getSocketFactory(), 80)); schemeRegistry.register( new Scheme("https", SSLSocketFactory.getSocketFactory(), 443)); ThreadSafeClientConnManager cm = new ThreadSafeClientConnManager(params, schemeRegistry); client = new DefaultHttpClient(cm,params); } public HTTPrequestHelper(ResponseHandler<String> responseHandler) { this.responseHandler = responseHandler; } public void performrequest(String url, String para) { HttpPost post = new HttpPost(url); StringEntity parameters; try { parameters = new StringEntity(para); post.setEntity(parameters); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } BasicHttpResponse errorResponse = new BasicHttpResponse( new ProtocolVersion("HTTP_ERROR", 1, 1), 500, "ERROR"); try { client.execute(post, this.responseHandler); } catch (Exception e) { errorResponse.setReasonPhrase(e.getMessage()); try { this.responseHandler.handleResponse(errorResponse); } catch (Exception ex) { Log.e( "ouch", "!!! IOException " + ex.getMessage() ); } } } I tried added the allow header to the request but that did not work as well but im not sure if i was doing right. below is the code. client.addRequestInterceptor(new HttpRequestInterceptor() { @Override public void process(HttpRequest request, HttpContext context) throws HttpException, IOException { //request.addHeader("Allow", "POST"); } });

  • asp.net mvc2 - controller for master page and code organization

    - by ile
    I've just finished my first ASP.NET MVC (2) CMS. Next step is to build website that will show data from CMS's database. This is website design: #1 (Red box) - displays article categories. ViewModel: public class CategoriesDisplay { public CategoriesDisplay() { } public int CategoryID { set; get; } public string CategoryTitle { set; get; } } #2 (Brown box) - displays last x articles; skips those from green box #3. Viewmodel: public class ArticleDisplay { public ArticleDisplay() { } public int CategoryID { set; get; } public string CategoryTitle { set; get; } public int ArticleID { set; get; } public string ArticleTitle { set; get; } public string URLArticleTitle { set; get; } public DateTime ArticleDate; public string ArticleContent { set; get; } } #3 (green box) - Displays last x articles. Uses the same ViewModel as brown box #2 #4 (blue box) - Displays list of upcoming events. Uses dataContext.Model.Event as ViewModel Boxes #1, #2 and #4 will repeat all over the site and they are part of Master Page. So, my question is: what is the best way to transfer this data from Model to Controller and finally to View pages? Should I make a controller for master page and ViewModel class that will wrap all this classes together OR Should I create partial Views for every of these boxes and make each of them inherit appropriate class (if it is even possible that it works this way?) OR Should I put this repeated code in all controllers and all additional data transfer via ViewData, which would be probably the worse way :) OR There is maybe a better and more simple way but I don't know/see it? Thanks in advance, Ile EDIT: If your answer is #1, then please explain how to make a controller for master page! EDIT 2: In this tutorial is described how to pass data to master page using abstract class: http://www.asp.net/LEARN/mvc/tutorial-13-cs.aspx In "Listing 5 – Controllers\MoviesController.cs", data is retrieved directly from database using LINQ, not from repository. So, I wonder if this is just in this tutorial, or there is some trick here and repository can't/shouldn't be used?

  • C# MP3 Player using winmm.dll

    - by JoeBeez
    I'm trying to bash together a (very) rough MP3 player during my lunch hour, and so far I've got it to play the files, and I'm working on a way of building a list of filenames to enable random songs, but I think I've just hit a snag. Is there a way of knowing when the currently playing MP3 has finished? An event or some such? As it stands I don't think I'd be able to have playlists etc unless this was possible due to it stopping after every playback. I've attatched the whole source below, feel free to pick it apart and give me any feedback you may have, cheers. using System; using System.IO; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Runtime.InteropServices; namespace X { public partial class Form1 : Form { List<string> Names = new List<string>(); StreamReader reader = File.OpenText(@"C:\X.txt"); string line; OpenFileDialog ofd = new OpenFileDialog(); StringBuilder buffer = new StringBuilder(128); string CommandString; [DllImport("winmm.dll")] private static extern long mciSendString(string lpstrCommand, StringBuilder lpstrReturnString, int uReturnLength, int hwndCallback); public Form1() { InitializeComponent(); while ((line = reader.ReadLine()) != null) { if (line.Trim() != "") { Names.Add(line.Trim()); } } } private void btnplay_Click(object sender, EventArgs e) { if (ofd.FileName == "") { if (ofd.ShowDialog() == DialogResult.OK) { ofd.Filter = "MP3 Files|*.mp3"; CommandString = "open " + "\"" + ofd.FileName + "\"" + " type MPEGVideo alias Mp3File"; mciSendString(CommandString, null, 0, 0); CommandString = "play Mp3File"; mciSendString(CommandString, null, 0, 0); } } else { CommandString = "play Mp3File"; mciSendString(CommandString, null, 0, 0); } } private void btnpause_Click(object sender, EventArgs e) { CommandString = "pause mp3file"; mciSendString(CommandString, null, 0, 0); } private void btnbrowse_Click(object sender, EventArgs e) { ofd.Filter = "Mp3 files |*.mp3"; if (ofd.ShowDialog() == DialogResult.OK) { txtpath.Text = ofd.FileName; CommandString = "close Mp3File"; mciSendString(CommandString, null, 0, 0); CommandString = "open " + "\"" + ofd.FileName + "\"" + " type MPEGVideo alias Mp3File"; mciSendString(CommandString, null, 0, 0); } } } }

  • Why does my layout repeats in device but looks fine on emulator when an image is added in a Relative Layout?

    - by Honey H
    let me try to explain clearly with what I want here. I have a RelativeLayout that contains a header image and the content below it. Now, when i have a header image and a list view below it, the page fits the screen in the device properly, the layout does not repeat. But when I place an image below the header image, the layout repeats in the device. Meaning i could see 2 header images in the device. Some page, I could see half of the header image that is not supposed to be there (repeated header image). However, in emulator, all the pages looks fine and fit the screen nicely. I tried changing to LinearLayout, RelativeLayout inside LinearLayout, Relative Layout, it gave me the same outcome. I hope someone could tell me why this happened. Thanks. Attached is my layout. <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:background="@drawable/bg" > <ImageView android:id="@+id/header" android:contentDescription="@string/image" android:src= "@drawable/header" android:layout_width="fill_parent" android:layout_height="wrap_content" android:adjustViewBounds="true" android:scaleType="centerCrop"/> <RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:orientation="vertical" > <ImageView android:id="@+id/journal" android:layout_width="150dp" android:layout_height="150dp" android:layout_alignTop="@+id/kick" android:adjustViewBounds="true" android:contentDescription="@string/image" android:padding="10dp" android:src="@drawable/favourite_journal" /> <ImageView android:id="@+id/kick" android:layout_width="150dp" android:layout_height="150dp" android:layout_toRightOf="@+id/journal" android:layout_below="@+id/header" android:adjustViewBounds="true" android:contentDescription="@string/image" android:padding="10dp" android:src="@drawable/favourite_kick" /> <ImageView android:id="@+id/labour" android:layout_width="150dp" android:layout_height="150dp" android:layout_below="@+id/journal" android:layout_alignLeft="@+id/journal" android:adjustViewBounds="true" android:contentDescription="@string/image" android:padding="10dp" android:src="@drawable/favourite_labour" /> <ImageView android:id="@+id/share" android:layout_width="150dp" android:layout_height="150dp" android:layout_below="@+id/kick" android:layout_alignLeft="@+id/kick" android:adjustViewBounds="true" android:contentDescription="@string/image" android:padding="10dp" android:src="@drawable/favourite_share" /> </RelativeLayout> </RelativeLayout>

  • JSF a4j:commandButton not working when 'disabled' is set

    - by Jon
    Hello, When I include a 'disabled' attribute on an a4j:commandButton, the button's action is not performed. Taking the 'disabled' attribute out causes it to work properly. I am not doing any special validation (that I'm aware of) and am not seeing any validation error messages. Here is part of my page: <t:dataTable id="myTable" var="region" value="#{MyPageBackingBean.regions}" width="100%"> ... <a4j:commandButton value="Update" action="#{region.doUpdate}" oncomplete="alert('done');" disabled="#{!empty region && region.messageEmpty}" immediate="true"/> ... </t:dataTable> Any ideas? Thanks! Edit: I tried setting preserveDataModel="true" on the t:dataTable to no avail. I also made a test having an a4j:commandButton and text box with no data table, but the backing bean action is still not being fired: <h:form> <a4j:region> <a4j:outputPanel id="testregion"> <h:messages id="messages"/> <a4j:status> <f:facet name="start"> <h:graphicImage value="/images/progress_indicator.gif"/> </f:facet> </a4j:status> <h:inputTextarea rows="5" value="#{MyPageBackingBean.myValue}" style="width:100%; border: 1px solid #99CCFF;"> <a4j:support event="onkeyup" reRender="testregion" eventsQueue="messageModificationQueue" ignoreDupResponses="true" requestDelay="500"/> </h:inputTextarea> <a4j:commandButton id="doDelete" value="Delete" action="#{MyPageBackingBean.dummy}" reRender="testregion" disabled="#{empty MyPageBackingBean.myValue}"/> <h:outputText value="#{MyPageBackingBean.myValue}"/> </a4j:outputPanel> </a4j:region> </h:form> Here is the new backing bean code used for testing: private String m_myValue = null; public String getMyValue() { return m_myValue; } public void setMyValue(String value) { m_myValue = value; } private String mystr2 = null; public String dummy() { mystr2 = "hello"; return null; } Thanks!

  • SSRS 2005 giving me "Invalid URI: The format of the URI could not be determined" when trying to cust

    - by Brian
    Hello, I'm getting the error "Invalid URI: The format of the URI could not be determined" when customizing it. I've made several changes to the configuration files and UI, but I keep getting this error. It isn't logging it too in the event log nor the log files, which makes it very annoying to debug. So how do I figure out where the error is coming from? Is it with the URL that's pointing to the ReportServer2005.asmx file, or something else? Updated: The specific error being logged is: aspnet_wp!library!9!3/11/2010-15:52:49:: i INFO: Initializing WatsonDumpOnExceptions to default value of 'Microsoft.ReportingServices.Diagnostics.Utilities.InternalCatalogException,Microsoft.ReportingServices.Modeling.InternalModelingException' because it was not specified in Configuration file. aspnet_wp!library!9!3/11/2010-15:52:49:: i INFO: Initializing WatsonDumpExcludeIfContainsExceptions to default value of 'System.Data.SqlClient.SqlException,System.Threading.ThreadAbortException' because it was not specified in Configuration file. aspnet_wp!library!9!3/11/2010-15:52:49:: i INFO: Initializing SecureConnectionLevel to default value of '1' because it was not specified in Configuration file. aspnet_wp!library!9!3/11/2010-15:52:49:: i INFO: Initializing DisplayErrorLink to 'True' as specified in Configuration file. aspnet_wp!library!9!3/11/2010-15:52:49:: i INFO: Initializing WebServiceUseFileShareStorage to default value of 'False' because it was not specified in Configuration file. aspnet_wp!ui!9!3/11/2010-15:52:52:: e ERROR: Invalid URI: The format of the URI could not be determined. aspnet_wp!ui!9!3/11/2010-15:52:53:: e ERROR: HTTP status code -- 500 -------Details-------- System.UriFormatException: Invalid URI: The format of the URI could not be determined. at Microsoft.SqlServer.ReportingServices2005.RSConnection.GetSecureMethods() at Microsoft.ReportingServices.UI.Global.RSWebServiceWrapper.GetSecureMethods() at Microsoft.SqlServer.ReportingServices2005.RSConnection.IsSecureMethod(String methodname) at Microsoft.SqlServer.ReportingServices2005.RSConnection.ValidateConnection() at Microsoft.ReportingServices.UI.Global.SecureAllAPI() at Microsoft.ReportingServices.UI.ReportingPage.EnsureHttpsLevel(HttpsLevel level) at Microsoft.ReportingServices.UI.ReportingPage.ReportingPage_Init(Object sender, EventArgs args) at System.EventHandler.Invoke(Object sender, EventArgs e) at System.Web.UI.Control.OnInit(EventArgs e) at System.Web.UI.Page.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) aspnet_wp!ui!9!3/11/2010-15:52:53:: e ERROR: Exception in ShowErrorPage: System.Threading.ThreadAbortException: Thread was being aborted. at System.Threading.Thread.AbortInternal() at System.Threading.Thread.Abort(Object stateInfo) at System.Web.HttpResponse.End() at System.Web.HttpServerUtility.Transfer(String path, Boolean preserveForm) at Microsoft.ReportingServices.UI.ReportingPage.ShowErrorPage(String errMsg) at at System.Threading.Thread.AbortInternal() at System.Threading.Thread.Abort(Object stateInfo) at System.Web.HttpResponse.End() at System.Web.HttpServerUtility.Transfer(String path, Boolean preserveForm) at Microsoft.ReportingServices.UI.ReportingPage.ShowErrorPage(String errMsg) Thanks.
