  • Baffled by differences between WPF BitmapEncoders

    - by DanM
    I wrote a little utility class that saves BitmapSource objects to image files. The image files can be either bmp, jpeg, or png. Here is the code: public class BitmapProcessor { public void SaveAsBmp(BitmapSource bitmapSource, string path) { Save(bitmapSource, path, new BmpBitmapEncoder()); } public void SaveAsJpg(BitmapSource bitmapSource, string path) { Save(bitmapSource, path, new JpegBitmapEncoder()); } public void SaveAsPng(BitmapSource bitmapSource, string path) { Save(bitmapSource, path, new PngBitmapEncoder()); } private void Save(BitmapSource bitmapSource, string path, BitmapEncoder encoder) { using (var stream = new FileStream(path, FileMode.Create)) { encoder.Frames.Add(BitmapFrame.Create(bitmapSource)); encoder.Save(stream); } } } Each of the three Save methods work, but I get unexpected results with bmp and jpeg. Png is the only format that produces an exact reproduction of what I see if I show the BitmapSource on screen using a WPF Image control. Here are the results: BMP - too dark JPEG - too saturated PNG - correct Why am I getting completely different results for different file types? I should note that the BitmapSource in my example uses an alpha value of 0.1 (which is why it appears very desaturated), but it should be possible to show the resulting colors in any image format. I know if I take a screen capture using something like HyperSnap, it will look correct regardless of what file type I save to. Here's a HyperSnap screen capture saved as a bmp: As you can see, this isn't a problem, so there's definitely something strange about WPF's image encoders. Do I have a setting wrong? Am I missing something?

  • WebClient Lost my Session

    - by kamiar3001
    Hi folks I have a problem first of all look at my web service method : [WebMethod(), ScriptMethod(ResponseFormat = ResponseFormat.Json)] public string GetPageContent(string VirtualPath) { WebClient client = new WebClient(); string content=string.Empty; client.Encoding = System.Text.Encoding.UTF8; try { if (VirtualPath.IndexOf("______") > 0) content = client.DownloadString(HttpContext.Current.Request.UrlReferrer.AbsoluteUri.Replace("Main.aspx", VirtualPath.Replace("__", "."))); else content = client.DownloadString(HttpContext.Current.Request.UrlReferrer.AbsoluteUri.Replace("Main.aspx", VirtualPath)); } catch { content = "Not Found"; } return content; } As you can see my web service method read and buffer page from it's localhost it works and I use it to add some ajax functionality to my web site it works fine but my problem is Client.DownloadString(..) lost all session because my sessions are all null which are related to this page for more description. at page-load in the page which I want to load from my web service I set session : HttpContext.Current.Session[E_ShopData.Constants.SessionKey_ItemList] = result; but when I click a button in the page this session is null I mean it can't transfer session. How I can solve this problem ? my web service is handled by some jquery code like following : $.ajax({ type: "Post", url: "Services/NewE_ShopServices.asmx" + "/" + "GetPageContent", data: "{" + "VirtualPath" + ":" + mp + "}", contentType: "application/json; charset=utf-8", dataType: "json", complete: hideBlocker, success: LoadAjaxSucceeded, async: true, cache: false, error: AjaxFailed });

  • JDO, GAE: Load object group by child's key

    - by tiex
    I have owned one-to-many relationship between two objects: @PersistenceCapable(identityType = IdentityType.APPLICATION) public class AccessInfo { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private com.google.appengine.api.datastore.Key keyInternal; ... @Persistent private PollInfo currentState; public AccessInfo(){} public AccessInfo(String key, String voter, PollInfo currentState) { this.voter = voter; this.currentState = currentState; setKey(key); // this key is unique in whole systme } public void setKey(String key) { this.keyInternal = KeyFactory.createKey( AccessInfo.class.getSimpleName(), key); } public String getKey() { return this.keyInternal.getName(); } and @PersistenceCapable(identityType = IdentityType.APPLICATION) public class PollInfo { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key key; @Persistent(mappedBy = "currentState") private List<AccessInfo> accesses; ... I created an instance of class PollInfo and make it persistence. It is ok. But then I want to load this group by AccessInfo key, and I am getting exception NucleusObjectNotFoundException. Is it possible to load a group by child's key?

  • Getting input and output from a jar file run from java class?

    - by Jack L.
    Hi, I have a jar file that runs this code: public class InputOutput { /** * @param args * @throws IOException */ public static void main(String[] args) throws IOException { boolean cont = true; BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); while (cont) { System.out.print("Input something: "); String temp = in.readLine(); if (temp.equals("end")) { cont = false; System.out.println("Terminated."); } else System.out.println(temp); } } } I want to program another java class that executes this jar file and can get the input and send output to it. Is it possible? The current code I have is this but it is not working: public class JarTest { /** * Test input and output of jar files * @author Jack */ public static void main(String[] args) { try { Process io = Runtime.getRuntime().exec("java -jar InputOutput.jar"); BufferedReader in = new BufferedReader(new InputStreamReader(io.getInputStream())); OutputStreamWriter out = new OutputStreamWriter(io.getOutputStream()); boolean cont = true; BufferedReader consolein = new BufferedReader(new InputStreamReader(System.in)); while (cont) { String temp = consolein.readLine(); out.write(temp); System.out.println(in.readLine()); } } catch (IOException e) { e.printStackTrace(); } } } Thanks for your help

  • UriMapper Problem

    - by jsop
    I have the following xaml (nonessential markup removed in the interest of brevity): <navigation:Frame x:Name="ContentFrame" > <navigation:Frame.UriMapper> <uriMapper:UriMapper> <uriMapper:UriMapping Uri="/{pageName}" MappedUri="/Views/{pageName}.xaml"/> <uriMapper:UriMapping Uri="/FMChart/{metricID}/{orgID}" MappedUri="/Views/FMChart.xaml?metricID={metricID}&orgID={orgID}"/> </navigation:Frame.UriMapper> </navigation:Frame.UriMapper> </navigation:Frame> I'm creating the HyperLinkButton objects dynamically (in code), like so: int metricID = 1; int orgID = 1; HyperlinkButton button = new HyperlinkButton(); button.Name = Guid.NewGuid().ToString(); button.TargetName = "ContentFrame"; // this string doesn't work string url = string.Format("/FMChart/{0}/{1}", metricID, orgID); button.NavigateUri = new Uri(url, UriKind.Relative); When I click the bbutton, the browser renders a blank page, and eventually presents me with a REALLY long stack trace (InvalidOperation exception). If I take the parameters out of th indicated line: string url = "/FMChart"; ...it works as expected (brings up the desired page). I've also tried the following strings: /FMChart/{0}&{1} /FMChart/{0}& amp;{1} What am I doing wrong?

  • Native functions throw UnsatisfiedLinkError in custom view, despite working in main activity

    - by Mark Ingram
    For some reason I can only call native functions from my main activity and not any custom views that I've created. Here is an example file (I followed a tutorial, but renamed the classes http://mindtherobot.com/blog/452/android-beginners-ndk-setup-step-by-step/) See the usage of the native function "getNewString". package com.example.native; import android.app.Activity; import android.app.AlertDialog; import android.content.Context; import android.graphics.Bitmap; import android.graphics.Canvas; import android.os.Bundle; import android.view.View; public class NativeTestActivity extends Activity { static { System.loadLibrary("nativeTest"); } private native String getNewString(); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.setContentView(new BitmapView(this)); String hello = getNewString(); // This line works fine new AlertDialog.Builder(this).setMessage(hello).show(); } } class BitmapView extends View { static { System.loadLibrary("nativeTest"); } private native String getNewString(); public BitmapView(Context context) { super(context); String hello = getNewString(); // This line throws the UnsatisfiedLinkError new AlertDialog.Builder(this.getContext()).setMessage(hello).show(); } } How can I call native functions in my custom views? I've built the application as an Android 2.2 app. I'm running the application on my HTC Desire. I have the latest SDK (9) and latest NDK (r5).

    Hi, I'm trying to get the html content of a page using silverlight. Webresponse and request classes don't work in silverlight. I did some googling and I found something. This is what i tried: public partial class MainPage : UserControl { string result; WebClient client; public MainPage() { InitializeComponent(); this.result = string.Empty; this.client = new WebClient(); this.client.DownloadStringCompleted += ClientDownloadStringCompleted; } private void btn1_Click(object sender, RoutedEventArgs e) { string url = "http://www.nu.nl/feeds/rss/algemeen.rss"; this.client.DownloadStringAsync(new Uri(url, UriKind.Absolute)); if (this.result != string.Empty && this.result != null) { this.txbSummery.Text = this.result; } } private void ClientDownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { this.result = e.Result; //handle the response. } } It gives me a runtime error after pressing the button: Microsoft JScript runtime error: Unhandled Error in Silverlight Application An exception occurred during the operation, making the result invalid.

    I am trying to programmaticly fill in a microsoft word form.

How do I get past this limitation? If I open the word doc in word I can type in more than 255 chars without a problem. Does anyone know how to input more characters via c# code? object fileName = strFileName; object readOnly = false; object isVisible = true; object missing = System.Reflection.Missing.Value; //open doc _oDoc = _oWordApplic.Documents.Open(ref fileName, ref missing, ref readOnly, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref isVisible, ref missing, ref missing, ref missing, ref missing); _oDoc.Activate(); //write string _oDoc.FormFields[oBookMark].Result = value; //save and close oDoc.SaveAs(ref fileName, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing); _oWordApplic.Application.Quit(ref missing, ref missing, ref missing);

  • WebService Stubs WSDL Axis2

    - by tt0686
    Good afternoon in my timezone. I have a wsdl file with the following snippet of code: <schema targetNamespace="http://util.cgd.pt" xmlns="http://www.w3.org/2001/XMLSchema"> <import namespace="http://schemas.xmlsoap.org/soap/encoding/" /> <complexType name="Attribute"> <sequence> <element name="fieldType" nillable="true" type="xsd:string" /> <element name="dataType" nillable="true" type="xsd:string" /> <element name="name" nillable="true" type="xsd:string" /> <element name="value" nillable="true" type="xsd:string" /> </sequence> </complexType> <complexType name="ArrayOffAttribute"> <complexContent> <restriction base="soapenc:Array"> <attribute ref="soapenc:arrayType" wsdl:arrayType="tns3:Attribute[]" /> </restriction> </complexContent> </complexType> When i use jax-rpc or Axis1 to generate the stubs the type Attribute is generated, but when i use Axis2 the type Attribute is not generated and a new type is created ArrayOffAttribute, this new type extends the axis2.databinding.types.soapencoding.Array and permits to add elements through the array.addObject(object), my question is, i am migrating one Java EE application from webservices using jax-rpc to start using Axis2, and the methods are using the Attribute type to fullfill attributes fields, now in Axis2 and do not have attribute type , what should i use in the ArrayOffAttribute.addObject(?) ? Could be something wrong with Axis2 ? i am stop here :( Thanks in advance Best regards

  • Multiple elements with the same name with SimpleXML and Java

    - by LouieGeetoo
    I'm trying to use SimpleXML to parse an XML document (an ItemLookupResponse for a book from the Amazon Product Advertising API) which contains the following element: <ItemAttributes> <Author>Shane Conder</Author> <Author>Lauren Darcey</Author> <Manufacturer>Pearson Educacion</Manufacturer> <ProductGroup>Book</ProductGroup> <Title>Android Wireless Application Development: Barnes & Noble Special Edition</Title> </ItemAttributes> My problem is that I don't know how to deal with the multiple possible Author elements. Here's what I have right now for the corresponding POJO (Plain Old Java Object), keeping in mind that it's not handling the case of multiple Authors: @Element public class ItemAttributes { @Element public String Author; @Element public String Manufacturer; @Element public String Title; } (I don't care about the ProductGroup, so it's not in the class -- I'm just setting SimpleXML's strict mode to off to allow for that.) I couldn't find an example in the documentation that corresponded with such a case. Using an ElementList with (inline=true) seemed along the right lines, but I didn't see how to do it for String (as opposed to a separate Author class, which I have no need for and don't see how it would even work). Here's a similar question and answer, but for PHP: php - simpleXML how to access a specific element with the same name as others? I don't know what the Java equivalent would be to the accepted answer. Thanks in advance.

  • Andriod Spinner not displaying list items.

    I think I am going crazy right now. I am trying to create a spinner populated by a datatable but for some reason the dropdown list items text is not being displayed. I have looked all over and have seen other posts with people having this same problem. Can anyone help?? speciesList = (Spinner) findViewById(R.id.speciesList); spinnerCursor = nsfdb.fetchAllSpecies(); startManagingCursor(spinnerCursor); //String []cArrayList = new String[]{"dog", "cat", "horse", "other"}; String[] from = new String[]{"species"}; int[] to = new int[]{R.id.text1}; SimpleCursorAdapter locations = new SimpleCursorAdapter(this, R.layout.loc_row, spinnerCursor, from, to); locations.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); speciesList.setAdapter(locations); The spinner gets created just fine and is populated with 4 items but whenever I click on the spinner I see 4 items with no text and just radiobuttons. If I select any of them I am getting the correct selected item value but there is just no data displayed.

  • Binding a ListBox's SelectedItem in the presence of BindingNavigator

    - by Reinderien
    Hello. I'm trying to bind a ListBox's SelectedItem data to a property. The following code is an example: using System; using System.Collections.Generic; using System.Windows.Forms; namespace BindingFailure { static class Program { class OuterObject { public string selected { get; set; } public List<string> strings { get; set; } } public static void Main() { List<OuterObject> objs = new List<OuterObject>() { new OuterObject(), new OuterObject() }; objs[0].strings = new List<string> { "one", "two", "three" }; objs[1].strings = new List<string> { "four", "five", "six" }; Form form = new Form(); BindingSource obs = new BindingSource(objs, null), ibs = new BindingSource(obs, "strings"); BindingNavigator nav = new BindingNavigator(obs); ListBox lbox = new ListBox(); lbox.DataSource = ibs; lbox.DataBindings.Add(new Binding("SelectedItem", obs, "selected")); form.Controls.Add(nav); form.Controls.Add(lbox); lbox.Location = new System.Drawing.Point(30, 30); Application.Run(form); } } } If you just select an item, move forward, select an item and then exit, it works as expected. But if you switch back and forth between the two outer objects with the navigator, the selected item seems to be overwritten with an incorrect value. Ideas on how to fix this? Thanks in advance.

  • ListView Parsing Persian xml

    - by Namikaze Minato
    I used a tutorial about listview parsing xm from internet and using LasyAdapter shows the items in listview. When I add persian characters in xml (into one of childnodes) the result is some boxes in listview (after showing the text in listview). The format of xml is UTF-8, too. I used typeface too (but didn't work). Besides when I type Pwesian into the application it shows alright but it can't show Persiann content parsed from xml. Thanks in advance. I updated the post with original XMLparser (which was the problem). public String getXmlFromUrl(String url) { String xml = null; try { // defaultHttpClient DefaultHttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(url); HttpResponse httpResponse = httpClient.execute(httpPost); HttpEntity httpEntity = httpResponse.getEntity(); xml = EntityUtils.toString(httpEntity); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } // return XML return xml; } public Document getDomElement(String xml) { Document doc = null; DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); try { DocumentBuilder db = dbf.newDocumentBuilder(); InputSource is = new InputSource(); is.setCharacterStream(new StringReader(xml)); doc = db.parse(is); } catch (ParserConfigurationException e) { Log.e("Error: ", e.getMessage()); return null; } catch (SAXException e) { Log.e("Error: ", e.getMessage()); return null; } catch (IOException e) { Log.e("Error: ", e.getMessage()); return null; } return doc; }

  • boost::asio::async_resolve Problem

    - by Moo-Juice
    Hi All, I'm in the process of constructing a Socket class that uses boost::asio. To start with, I made a connect method that took a host and a port and resolved it to an IP address. This worked well, so I decided to look in to async_resolve. However, my callback always gets an error code of 995 (using the same destination host/port as when it worked synchronously). code: Function that starts the resolution: // resolve a host asynchronously template<typename ResolveHandler> void resolveHost(const String& _host, Port _port, ResolveHandler _handler) const { boost::asio::ip::tcp::endpoint ret; boost::asio::ip::tcp::resolver::query query(_host, boost::lexical_cast<std::string>(_port)); boost::asio::ip::tcp::resolver r(m_IOService); r.async_resolve(query, _handler); }; // eo resolveHost Code that calls this function: void Socket::connect(const String& _host, Port _port) { // Anon function for resolution of the host-name and asynchronous calling of the above auto anonResolve = [this](const boost::system::error_code& _errorCode, boost::asio::ip::tcp::resolver_iterator _epIt) { // raise event onResolve.raise(SocketResolveEventArgs(*this, !_errorCode ? (*_epIt).host_name() : String(""), _errorCode)); // perform connect, calling back to anonymous function if(!_errorCode) connect(*_epIt); }; // Resolve the host calling back to anonymous function Root::instance().resolveHost(_host, _port, anonResolve); }; // eo connect The message() function of the error_code is: The I/O operation has been aborted because of either a thread exit or an application request And my main.cpp looks like this: int _tmain(int argc, _TCHAR* argv[]) { morse::Root root; TextSocket s; s.connect("somehost.com", 1234); while(true) { root.performIO(); // calls io_service::run_one() } return 0; } Thanks in advance!

  • JPA - Entity design problem

    - by Yatendra Goel
    I am developing a Java Desktop Application and using JPA for persistence. I have a problem mentioned below: I have two entities: Country City Country has the following attribute: CountryName (PK) City has the following attribute: CityName Now as there can be two cities with same name in two different countries, the primaryKey for City table in the datbase is a composite primary key composed of CityName and CountryName. Now my question is How to implement the primary key of the City as an Entity in Java @Entity public class Country implements Serializable { private String countryName; @Id public String getCountryName() { return this.countryName; } } @Entity public class City implements Serializable { private CityPK cityPK; private Country country; @EmbeddedId public CityPK getCityPK() { return this.cityPK; } } @Embeddable public class CityPK implements Serializable { public String cityName; public String countryName; } Now as we know that the relationship from Country to City is OneToMany and to show this relationship in the above code, I have added a country variable in City class. But then we have duplicate data(countryName) stored in two places in the City class: one in the country object and other in the cityPK object. But on the other hand, both are necessary: countryName in cityPK object is necessary because we implement composite primary keys in this way. countryName in country object is necessary because it is the standard way of showing relashionship between objects. How to get around this problem?

  • openssl crypto library - base64 conversion

    - by Hassan Syed
    I'm using openssl BIO objects to convert a binary string into a base64 string. The code is as follows: void ToBase64(std::string & s_in) { BIO * b_s = BIO_new( BIO_s_mem() ); BIO * b64_f = BIO_new( BIO_f_base64() ); b_s = BIO_push( b64_f , b_s); std::cout << "IN::" << s_in.length(); BIO_write(b_s, s_in.c_str(), s_in.length()); char * pp; int sz = BIO_get_mem_data(b_s, &pp); std::cout << "OUT::" << sz << endl; s_in.assign(pp,sz); //std::cout << sz << " " << std::string(pp,sz) << std::endl; BIO_free (b64_f); // TODO ret error potential BIO_free (b_s); // } The in length is either 64 or 72. However the output is always 65, which is incorrect it should be much larger than that. The documentation isn't the best in the world, AFAIK the bio_s_mem object is supposed to grow dynamically. What am I doing wrong ?

  • How can I tell whether a webpart that has been deployed to a site is a native webpart that ships wit

    - by program247365
    I have a SharePoint 2007 MOSS instance, and I'm on a fact-finding mission. There have been multiple developers, developing multiple webparts and deploying them (using VS2005/2008 SharePoint Extensions). I thought maybe I could look at the fields in the "Web Part Gallery" list in my site, and look by "Modified by", but it looks like a developer's name is on some of the out-of-the-box webparts somehow, and on ones I know are custom developed, they say "System Account" - so looking at that field in this list is a no go. I thought then maybe I could look at the "Group" to which each webpart was assigned but it looks like they were arbitrarily assigned to many different groups inconsistently - so using that piece of information is a no go. Here is my code I have for just looping through and getting the names of all the webparts. Is there any property I can access on the list items of webparts that would tell me whether it's a custom developed webpart? Any way to distinguish the custom webparts from the out-of-the-box ones? Is there another way to do this? #region Misc Site Collection Methods public static List<string> GetAllWebParts(string connectedSPInstanceUrl) { List<string> lstWebParts = new List<string>(); try { using (SPSite site = new SPSite(connectedSPInstanceUrl)) { using (SPWeb web = site.OpenWeb()) { SPList list = web.Lists["Web Part Gallery"]; foreach (SPListItem item in list.Items) { lstWebParts.Add(item.Name); } } } } catch (Exception ex) { lstWebParts.Add("Error"); lstWebParts.Add("Message: " + ex.Message); lstWebParts.Add("Inner Exception: " + ex.InnerException.ToString()); lstWebParts.Add("Stack Trace: " + ex.StackTrace); } return lstWebParts; } #endregion

  • How to retrieve a numbered sequence range from a List of filenames?

    - by glenneroo
    I would like to automatically parse the entire numbered sequence range of a List<FileData> of filenames (sans extensions) by checking which part of the filename changes. Here is an example (file extension already removed): First filename: IMG_0000 Last filename: IMG_1000 Numbered Range I need: 0000 to 1000 Except I need to deal with every possible type of file naming convention such as: 0000 ... 9999 20080312_0000 ... 20080312_9999 IMG_0000 - Copy ... IMG_9999 - Copy 8er_green3_00001 .. 8er_green3_09999 etc. I need the entire 0-padded range e.g. 0001 not just 1 The sequence number is 0-padded e.g. 0001 The sequence number can be located anywhere e.g. IMG_0000 - Copy The range can start and end with anything i.e. doesn't have to start with 1 and end with 9999 Whenever I get something working for 8 random test cases, the 9th test breaks everything and I end up re-starting from scratch. I've currently been comparing only the first and last filenames (as opposed to iterating through all filenames): void FindRange(List<FileData> files, out string startRange, out string endRange) { string firstFile = files.First().ShortName; string lastFile = files.Last().ShortName; ... } Does anyone have any clever ideas?
