  • Android Reading from an Input stream efficiently

    - by RenegadeAndy
    Hey, I am making an HTTP get request to a website for an android application I am making. I am using a DefaultHttpClient and using HttpGet to issue the request. I get the entity response and from this obtain an InputStream object for getting the html of the page. I then cycle through the reply doing as follows: BufferedReader r = new BufferedReader(new InputStreamReader(inputStream)); String x = ""; x = r.readLine(); String total = ""; while(x!= null){ total += x; x = r.readLine(); } However this is horrendously slow. Is this inefficient? I'm not loading a big web page - www.cokezone.co.uk so the file size is not big. Is there a better way to do this? Thanks Andy

  • Adding a imageview to child elements in a expandable list query

    - by Thomas Millin
    I am looking to find out how to assign an image to a imageview in each child of an expandable list. If anyone has any information or links to find out how to do this I would be most appreciative. expListAdapter = new SimpleExpandableListAdapter( main.this, createGroupList(), R.layout.parentnode, new String[] { "day", "number" }, new int[] { R.id.TextView01, R.id.TextView02 }, createChildList(), R.layout.child_row, new String[] { "image", "childName", "date"}, new int[] { R.id.ImageView01, R.id.childname, R.id.date } ); setListAdapter( expListAdapter ); is what my adapter looks like at the moment, I have very little experience in customising adapters so I do not know where to start. Any help would be great :D

    - by dotnetdev
    Hi, How is it possible to resume code execution after an exception is thrown? For exampel, take the following code: namespace ConsoleApplication1 { class Test { public void s() { throw new NotSupportedException(); string @class = "" ; Console.WriteLine(@class); Console.ReadLine(); } } class Program { static void Main(string[] args) { try { new Test().s(); } catch (ArgumentException x) { } catch (Exception ex) { } } } } After catching the exception when stepping through, the program will stop running. How can I still carry on execution? Thanks

  • How to access a structure member in a function that get it as void* type?

    - by Ahmad
    I want to have a function that accepts different type of structures as argument. So, since I don't have a specific type, I have to use void*. Now question is: when I pass a structure to this function, how can I access a known member of this structure inside the function? Specifically, I know that all structures have str1 as a member and I want, for example, print it. Here is a sample code: struct { char* str1; float tt1; } var1 = {"This is me", 12}; struct { char* str1; int tt2; } var2 = {"This is you", 18}; void printStruct(void* str) { printf("\n the structure string is %s", ??); //can I put something in ?? to print the string? } main(....) { printStruct(&var1); printStruct(&var2); }

  • NHibernate Many to Many delete all my data in the table

    - by Daoming Yang
    I would love to thank @Stefan Steinegger and @David helped me out yesterday with many-to-many mapping. I have 3 tables which are "News", "Tags" and "News_Tags" with Many-To-Many relationship and the "News_Tags" is the link table. If I delete one of the news records, the following mappings will delete all my news records which have the same tags. One thing I need to notice, I only allowed unique tag stored in the "Tag" table. This mapping make sense for me, it will delete the tag and related News records, but how can I implement a tagging system with NHibernate? Can anyone give me some suggestion? Many thanks. Daoming. News Mapping: <class name="New" table="News" lazy="false"> <id name="NewID"> <generator class="identity" /> </id> <property name="Title" type="String"></property> <property name="Description" type="String"></property> <set name="TagsList" table="New_Tags" lazy="false" inverse="true" cascade="all"> <key column="NewID" /> <many-to-many class="Tag" column="TagID" /> </set> </class> Tag Mapping: <class name="Tag" table="Tags" lazy="false"> <id name="TagID"> <generator class="identity" /> </id> <property name="TagName" type="String"></property> <property name="DateCreated" type="DateTime"></property> <!--inverse="true" has been defined in the "News mapping"--> <set name="NewsList" table="New_Tags" lazy="false" cascade="all"> <key column="TagID" /> <many-to-many class="New" column="NewID" /> </set> </class>

Alright, I don't want to get picky here, but is my reader open or closed?

  • help Implementing Object Oriented ansi-C approach??

    - by No Money
    Hey there, I am an Intermediate programmer in Java and know some of the basics in C++. I recently started to scam over "C language" [please note that i emphasized on C language and want to stick with C as i found it to be a perfect tool, so no need for suggestions focusing on why should i move back to C++ or Java]. Moving on, I code an Object Oriented approach in C but kindda scramble with the pointers part. Please understand that I am just a noob trying to extend my knowledge beyond what i learned in High School. Here is my code..... #include <stdio.h> typedef struct per{ int privateint; char *privateString; struct per (*New) (); void (*deleteperOBJ) (struct t_person *); void (*setperNumber) ((struct*) t_person,int); void (*setperString) ((struct*) t_person,char *); void (*dumpperState) ((struct*) t_person); }t_person; void setperNumber(t_person *const per,int num){ if(per==NULL) return; per->privateint=num; } void setperString(t_person *const per,char *string){ if(per==NULL) return; per->privateString=string; } void dumpperState(t_person *const per){ if(per==NULL) return; printf("value of private int==%d\n", per->privateint); printf("value of private string==%s\n", per->privateString); } void deleteperOBJ(struct t_person *const per){ free((void*)t_person->per); t_person ->per = NULL; } main(){ t_person *const per = (struct*) malloc(sizeof(t_person)); per = t_person -> struct per -> New(); per -> setperNumber (t_person *per, 123); per -> setperString(t_person *per, "No money"); dumpperState(t_person *per); deleteperOBJ(t_person *per); } Just to warn you, this program has several errors and since I am a beginner I couldn't help except to post this thread as a question. I am looking forward for assistance. Thanks in advance.

  • Poor man's "lexer" for C#

    - by Paul Hollingsworth
    I'm trying to write a very simple parser in C#. I need a lexer -- something that lets me associate regular expressions with tokens, so it reads in regexs and gives me back symbols. It seems like I ought to be able to use Regex to do the actual heavy lifting, but I can't see an easy way to do it. For one thing, Regex only seems to work on strings, not streams (why is that!?!?). Basically, I want an implementation of the following interface: interface ILexer : IDisposable { /// <summary> /// Return true if there are more tokens to read /// </summary> bool HasMoreTokens { get; } /// <summary> /// The actual contents that matched the token /// </summary> string TokenContents { get; } /// <summary> /// The particular token in "tokenDefinitions" that was matched (e.g. "STRING", "NUMBER", "OPEN PARENS", "CLOSE PARENS" /// </summary> object Token { get; } /// <summary> /// Move to the next token /// </summary> void Next(); } interface ILexerFactory { /// <summary> /// Create a Lexer for converting a stream of characters into tokens /// </summary> /// <param name="reader">TextReader that supplies the underlying stream</param> /// <param name="tokenDefinitions">A dictionary from regular expressions to their "token identifers"</param> /// <returns>The lexer</returns> ILexer CreateLexer(TextReader reader, IDictionary<string, object> tokenDefinitions); } So, pluz send the codz... No, seriously, I am about to start writing an implementation of the above interface yet I find it hard to believe that there isn't some simple way of doing this in .NET (2.0) already. So, any suggestions for a simple way to do the above? (Also, I don't want any "code generators". Performance is not important for this thing and I don't want to introduce any complexity into the build process.)

  • Entity Framework 4.1 (Code First) audit column

    - by Ken Pespisa
    I'm using Entity Framework 4.1 with a Code-First approach on an ASP.NET MVC site Say I have an entity named Profile that keeps track of a user's favorite book, and I want to track when the user updates their favorite book. UPDATED: Using the class below as an example, I want to set the FavoriteBookLastUpdated property to the current date whenever the value of the FavoriteBook property changes. public class Profile { public int Id { get; set; } public string Name { get; set; } public string FavoriteBook { get; set; } public DateTime? FavoriteBookLastUpdated { get; set; } } Right now I just update that field, if appropriate, in the controller's Edit action before calling the DBContext's SaveChanges() method. Is there a way I can put that logic in my model somehow? I'd prefer not to use triggers on the database side.

  • HttpWebRequest possibly slowing website

    - by Steven Smith
    Using Visual studio 2012, C#.net 4.5 , SQL Server 2008, Feefo, Nopcommerce Hey guys I have Recently implemented a new review service into a current site we have. When the change went live the first day all worked fine. Since then though the sending of sales to Feefo hasnt been working, There are no logs either of anything going wrong. In the OrderProcessingService.cs in Nop Commerce's Service, i call a HttpWebrequest when an order has been confirmed as completed. Here is the code. var email = HttpUtility.UrlEncode(order.Customer.Email.ToString()); var name = HttpUtility.UrlEncode(order.Customer.GetFullName().ToString()); var description = HttpUtility.UrlEncode(productVariant.ProductVariant.Product.MetaDescription != null ? productVariant.ProductVariant.Product.MetaDescription.ToString() : "product"); var orderRef = HttpUtility.UrlEncode(order.Id.ToString()); var productLink = HttpUtility.UrlEncode(string.Format("myurl/p/{0}/{1}", productVariant.ProductVariant.ProductId, productVariant.ProductVariant.Name.Replace(" ", "-"))); string itemRef = ""; try { itemRef = HttpUtility.UrlEncode(productVariant.ProductVariant.ProductId.ToString()); } catch { itemRef = "0"; } var url = string.Format("feefo Url", login, password,email,name,description,orderRef,productLink,itemRef); var request = (HttpWebRequest)WebRequest.Create(url); request.KeepAlive = false; request.Timeout = 5000; request.Proxy = null; using (var response = (HttpWebResponse)request.GetResponse()) { if (response.StatusDescription == "OK") { var stream = response.GetResponseStream(); if(stream != null) { using (var reader = new StreamReader(stream)) { var content = reader.ReadToEnd(); } } } } So as you can see its a simple webrequest that is processed on an order, and all product variants are sent to feefo. Now: this hasnt been happening all week since the 15th (day of the implementation) the site has been grinding to a halt recently. The stream and reader in the the var content is there for debugging. Im wondering does the code redflag anything to you that could relate to the process of website? Also note i have run some SQL statements to see if there is any deadlocks or large escalations, so far seems fine, Logs have also been fine just the usual logging of Bots. Any help would be much appreciated! EDIT: also note that this code is in a method that is called and wrapped in A try catch UPDATE: well forget about the "not sending", thats because i was just told my code was rolled back last week

  • Trying to filter a ListView with runQueryOnBackgroundThread but nothing happens - what am I missing?

    - by Ian Leslie
    I have a list of countries in a database. I have created a select country activity that consists of a edit box for filtering and a list which displays the flag and country name. When the activity starts the list shows the entire list of countries sorted alphabetically - works fine. When the customer starts typing into the search box I want the list to be filtered based on their typing. My database query was previously working in an AutoCompleteView (I just want to switch to a separate text box and list) so I know my full query and my constraint query are working. What I did was add a TextWatcher to the EditText view and every time the text is changed I invoke the list's SimpleCursorAdapter runQueryOnBackgroundThread with the edit boxes text as the constraint. The trouble is the list is never updated. I have set breakpoints in the debugger and the TextWatcher does make the call to runQueryOnBackgroundThread and my FilterQueryProvider is called with the expected constraint. The database query goes fine and the cursor is returned. The cursor adapter has a filter query provider set (and a view binder to display the flag): SimpleCursorAdapter adapter = new SimpleCursorAdapter (this, R.layout.country_list_row, countryCursor, from, to); adapter.setFilterQueryProvider (new CountryFilterProvider ()); adapter.setViewBinder (new FlagViewBinder ()); The FitlerQueryProvider: private final class CountryFilterProvider implements FilterQueryProvider { @Override public Cursor runQuery (CharSequence constraint) { Cursor countryCursor = myDbHelper.getCountryList (constraint); startManagingCursor (countryCursor); return countryCursor; } } And the EditText has a TextWatcher: myCountrySearchText = (EditText)findViewById (R.id.entry); myCountrySearchText.setHint (R.string.country_hint); myCountrySearchText.addTextChangedListener (new TextWatcher() { @Override public void afterTextChanged (Editable s) { SimpleCursorAdapter filterAdapter = (SimpleCursorAdapter)myCountryList.getAdapter (); filterAdapter.runQueryOnBackgroundThread (s.toString ()); } @Override public void onTextChanged (CharSequence s, int start, int before, int count) { // no work to do } @Override public void beforeTextChanged (CharSequence s, int start, int count, int after) { // no work to do } }); The query for the database looks like this: public Cursor getCountryList (CharSequence constraint) { if (constraint == null || constraint.length () == 0) { // Return the full list of countries return myDataBase.query (DATABASE_COUNTRY_TABLE, new String[] { KEY_ROWID, KEY_COUNTRYNAME, KEY_COUNTRYCODE }, null, null, null, null, KEY_COUNTRYNAME); } else { // Return a list of countries who's name contains the passed in constraint return myDataBase.query (DATABASE_COUNTRY_TABLE, new String[] { KEY_ROWID, KEY_COUNTRYNAME, KEY_COUNTRYCODE }, "Country like '%" + constraint.toString () + "%'", null, null, null, "CASE WHEN Country like '" + constraint.toString () + "%' THEN 0 ELSE 1 END, Country"); } } It just seems like there is a missing link somewhere. Any help would be appreciated. Thanks, Ian

  • I have a question about URI templates in WCF Services

    I have a web service with following operation contract and my service is hosted at http://localhost:9002/Service.svc/ [OperationContract] [WebGet(UriTemplate = "/Files/{Filepath}")] Stream DownloadFile(string Filepath); This web service would let users download file, if the proper filepath is provided (assuming, I somehow find out that proper filepath). Now, I can access this service from a browser by typing, http://localhost:9002/Service.svc/Files/(Filepath} If {filepath} is some simple string, its not a problem, but I want to send the location of the file. Lets us say users want to download file C:\Test.mp3 on the server. But how can I pass C:\Test.mp3 as {Filepath}? I get an error when I type http://localhost:9002/Service.svc/Files/C:\Test.mp3 in the browser. I am new to web services and find that this community is the quickest way to get answers to my questions.
