• Getting req.params in order in Express JS

  - by Adam Terlson

  In Express, is there a way to get the arguments passed from the matching route in the order they are defined in the route? I want to be able to apply all the params from the route to another function. The catch is that those parameters are not known up front, so I cannot refer to each parameter by name explicitly. app.get(':first/:second/:third', function (req) { output.apply(this, req.mysteryOrderedArrayOfParams); // Does this exist? }); function output() { for(var i = 0; i < arguments.length; i++) { console.log(arguments[i]); } } Call on GET: "/foo/bar/baz" Desired Output (in this order): foo bar baz

• check compiler with break point

  - by KareemSaad

  When I tried to focus on compiler in code i made break point on code if (!IsPostBack) { using (SqlConnection Con = Connection.GetConnection()) { if (Request.QueryString["Category_Id"] != null && DDlProductFamily.SelectedIndex < 0) { SqlCommand Com = new SqlCommand("SelectAllCtageories_Front", Con); Com.CommandType = CommandType.StoredProcedure; Com.Parameters.Add(Parameter.NewInt("@Category_Id", Request.QueryString["Category_Id"])); SqlDataAdapter DA = new SqlDataAdapter(Com); DA.Fill(dt); DataList1.DataSource = dt; DataList1.DataBind(); } but I cannot check condition although I had the value of query string List item

• How to pass a const unsigned char * from c++ to c#

  - by tzup

  So I have a function in unmanaged c++ that gets called when some text happens to have "arrived": #using <MyParser.dll> ... void dump_body(const unsigned char *Body, int BodyLen) { // Need to pass the body to DumpBody, but as what type? ... lMyParser::Parser::DumpBody(???); } DumpBody is a function defined in a C# DLL that should take one parameter of type? Body holds an array of characters (text) of length BodyLen. There's obviously some marshalling to be done here but I have no idea how. Please help.

• Easy way to apply a function to an array

  - by alex

  I am aware of array_walk() and array_map(). However when using the former like so (on an old project) it failed array_walk($_POST, 'mysql_real_escape_string'); Warning: mysql_real_escape_string() expects parameter 2 to be resource, string given. So I went with this slightly more ugly version foreach($_POST as $key => $value) { $_POST[$key] = mysql_real_escape_string($value); } So why didn't the first way work? What is the best way to map values of an array to a function?

• How does the stream manipulators work?

  - by Narek

  It is well known that the user can define stream manipulators like this: ostream& tab(ostream & output) { return output<< '\t'; } And this can be used in main() like this: cout<<'a'<<tab<<'b'<<'c'<<endl; Please explain me how does this all work? If operator<< assumes as a second parameter a pointer to the function that takes and returns ostream &, then please explain my why it is necessary? What would be wrong if the function does not take and return ostream & but it was void instead of ostream &? Also it is interesting why “dec”, “hex” manipulators take effect until I don’t change between them, but user defined manipulators should be always used in order to take effect for each streaming?

• Can I use a single instance of a delegate to start multiple Asynchronous Requests?

  - by RobV

  Just wondered if someone could clarify the use of BeginInvoke on an instance of some delegate when you want to make multiple asynchronous calls since the MSDN documentation doesn't really cover/mention this at all. What I want to do is something like the following: MyDelegate d = new MyDelegate(this.TargetMethod); List<IAsyncResult> results = new List<IAsyncResult>(); //Start multiple asynchronous calls for (int i = 0; i < 4; i++) { results.Add(d.BeginInvoke(someParams, null, null)); } //Wait for all my calls to finish WaitHandle.WaitAll(results.Select(r => r.AsyncWaitHandle).ToArray()); //Process the Results The question is can I do this with one instance of the delegate or do I need an instance of the delegate for each individual call? Given that EndInvoke() takes an IAsyncResult as a parameter I would assume that the former is correct but I can't see anything in the documentation to indicate either way.

• How to create a 2D map of room by a few images/movie frames ?

  - by Nils

  I'd like to create a simple 2D map of a room by getting pictures (ceiling) of all directions (360° - e.g. movie frames), recognize the walls by edge detection, delete other unwanted objects, concat the images at the right position (cf. walls, panorama) and finally create the approximate 2D map (looking on it from above). Getting the scale would be another parameter, which might be useful. I have some own ideas at the moment, by using e.g. the Sobel algorithm, but it would be interesting if somebody out there knows some project or software (GPL,freeware prefered) doing this already, as I'm still looking for some examples, which might help me. Thanks.

• How to use php variables (arrays) in mysql select statements?

  - by davidconn

  Hi everybody, How do you use a php variable (array) inside a mysql select statement? I am designing an auction site and currently working on a page that lets people view a list of all the current bids for an item. I want to display 3 columns: amountbid - the amount each bidder has bid for the item (held in tblbid) bidderid - the id of each bidder who has bid (found in tbluser) total_positivity_feedback - how many users have left positive feedback for the bidder (calculated from tblfeedback) To find the 'amount' and the 'bidderid' columns i pass the essayid URL parameter from the previous page. This works fine. Despite this, i can't display the total_positivity_feedback column for the various users who have made each bid. My mysql query looks like this: select tblbid.bidderid, tblbid.amount, (select count(tblfeedback.feedbackid) from tblfeedback WHERE tblfeedback.writerid = "ARRAY VARIABLE GOES HERE") AS total_positivity_feedback FROM tblbid WHERE tblbid.essayid = $essayid_bids I assume that the only way to accomplish this is to make the variable contain the bidderid's of those people who bid for that particular essay? I can't seem to work out how to do this tho?!? Many thanks for your help

• need a virtual template member workaround

  - by yurib

  Hello, I need to write a program implementing the visitor design pattern. The problem is that the base visitor class is a template class. This means that BaseVisited::accept() takes a template class as a parameter and since it uses 'this' and i need 'this' to point to the correct runtime instance of the object, it also needs to be virtual. I'd like to know if there's any way around this problem. template <typename T> class BaseVisitor { public: BaseVisitor(); T visit(BaseVisited *visited); virtual ~BaseVisitor(); } class BaseVisited { BaseVisited(); template <typename T> virtual void accept(BaseVisitor<T> *visitor) { visitor->visit(this); }; // problem virtual ~BaseVisited(); }

• How to update (append to) an href in jquery?

  - by John Isaacks

  I have a list of links that all go to a google maps api. the links already have the daddr (destination) parameter in them as static. I am using Geo-Location to find the users position and I want to add the saddr (source address) to the links once I get the data. so basically I will need to add something like &saddr=50.1234567,-50.03452 at the tail end of all the links pointing to google maps All the links have a class called directions-link and from this page I have figured out how to change them: $("a.directions-link").attr("href", "http://www.google.com/"); However I only want to append my value to the end of the href without changing what the href already is. How can I do that? Thanks!!

• Why can't I enforce derived classes to have parameterless constructors?

  - by FrisbeeBen

  I am trying to do the following: public class foo<T> where T : bar, new() { public foo() { _t = new T(); } private T _t; } public abstract class bar { public abstract void someMethod(); // Some implementation } public class baz : bar { public overide someMethod(){//Implementation} } And I am attempting to use it as follows: foo<baz> fooObject = new foo<baz>(); And I get an error explaining that 'T' must be a non-abstract type with a public parameterless constructor in order to use it as parameter 'T' in the generic type or method. I fully understand why this must be, and also understand that I could pass a pre-initialized object of type 'T' in as a constructor argument to avoid having to 'new' it, but is there any way around this? any way to enforce classes that derive from 'bar' to supply parameterless constructors?

• Stored procedure for selecting multiple records

  - by padmavathi

  I need to select records say 2000 from a table with a matching timestamp from c# .net code. Eg: SELECT * FROM ITEMDATA_TABLE WHERE ITEMNAME='Item1' and TimeStamp='2010-04-26 17:15:05.667' The above query has to execute for 2000 items more for the same timestamp. for this we can use SELECT * FROM ITEMDATA_TABLE WHERE ITEMNAME in ('Item1','Item2','Item3','Item4',......) AND TimeStamp='2010-04-26 17:15:05.667' from SQL Server Management Studio. I have tried appending all Item names to one string variable and giving it as a parameter to the stored procedure,but it resulted into a wrong concatenation. How can I do this as a stored procedure executing from the .net code? Can anyone suggest me/correct me in doing this? Thanks & Regards Padma

• Define thread in C++

  - by Vsevywniy

  How do I start a thread using _beginthreadex(), making it execute void myFunction(wchar_t *param);? I try to use this: _beginthread(NULL, 0, myFunction, L"someParam", 0, &ThreadID); but there is compilation error: error C2664: 'beginthreadex' : cannot convert parameter 3 from 'void (_cdecl *)(wchar_t *)' to 'unsigned int (__stdcall *)(void *)'. How I can resolve this error? I seem able to do _beginthread((void(*)(void*))myFunction, 0 , (void *)L"someParam");. But for _beginthreadex() these casts don't seem to work. What do I need to do?

• Beginner C++ Question

  - by Donal Rafferty

  I have followed the code example here toupper c++ example And implemented it in my own code as follows void CharString::MakeUpper() { char* str[strlen(m_pString)]; int i=0; str[strlen(m_pString)]=m_pString; char* c; while (str[i]) { c=str[i]; putchar (toupper(c)); i++; } } But this gives me the following compiler error CharString.cpp: In member function 'void CharString::MakeUpper()': CharString.cpp:276: error: invalid conversion from 'char*' to 'int' CharString.cpp:276: error: initializing argument 1of 'int toupper(int)' CharString.cpp: In member function 'void CharString::MakeLower()': This is line 276 putchar (toupper(c)); I understand that toupper is looking for int as a parameter and returns an int also, is that the problem? If so how does the example work?

• Rails - Rendering a Partial without having to use "_" in front of the filename?

  - by bluedevil2k

  How do I render a partial without having to supply the "_" in front of the file name? Is there a parameter I can call to not use it? This problem popped up using RABL and Backbone - using RABL requires me to have a file in my views like "index.json.rabl". But, when I use embed the JSON right on the page load (as is usual with Backbone), I'm required to call the file "index.json.rabl". These 2 files are the exact same thing, just required to have different names. I'm looking to use just 1 file, "index.json.rabl" and force the render() function to look for that file name, without the "".

• Why is this consider bad practice? or is it? (ASP.Net)

  - by user318573

  Would this code be considered bad practice: <div id="sidebar"> <% =DisplayMeetings(12) %> </div> This is a snippet of code from the default.aspx of a small web app I have worked on. It works perfectly well, runs very fast, but as always, I am aware of the fact that just because it works, doesn't mean it is OK. Basically, the DisplayMeetings subroutine outputs a bunch of formatted HTML (an unordered list actually), with no formatting, just the requisite html, and then my CSS performs all the necessary formatting. The data for generating the list comes from an SQL server database (the parameter controls how many rows to return) and I am using stored procedures and datareader for fast access. This keeps my front-end extraordinary simple and clean, imho, and lets me do all the work in VB or C# in a separate module. I could of course use a databound repeater (and probably 6 or more other methods) of accomplishing the same thing, but are they any better? Other than loosing the design-time features of VS2010?

• calling a service layer method to my presentation layer

  - by Josepth Vodary

  Ok I feel really dumb asking this but I seem to be missing something really simple here. I have the following code in a class in my service layer - public Items getItems(String category, float amount, String color, String type) The code reads from a database and returns the results - I plan on placing it in a jframe. Nice and simple. But no matter how I call it from the jframe I get errors in eclipse that the code is wrong - either that their are illegal modifiers or such. So obviously I am calling it completely wrong, so my stupid question is how do you call that method into a jframe? For example - if I try to call it this way: public Items getItems(); I get told that getItems is an illegal parameter. If I call this.. Items getItems(); I am told its undefined

• Inferring type from method generics

  - by ng

  I am from a Java background and I am looking from the equivalent in c# for the following. public interface Reader { <T> T read(Class<? extends T> type); } Such that I can do the following, constraining the parameter and inferring the return type. Cat cat = reader.read(Cat.class); Dog dog = reader.read(Dog.class); I was hoping something like this would work in c# but I am not sure it will. public interface Reader { T Read<T>(); } And and do this. public class TypeReader : Reader { public T Read<T>() { Type type = T.GetType(); ... } } Is something like this even possible in c#?

• Send data over telnet without pressing enter

  - by Matt

  I've recently started messing around with Java sockets and telnet... I want the user to be able to connect to the server, just type a letter and have it sent to the server, without pressing enter to send it. I'm sure there's no way for the server to set this up, but maybe telnet has a parameter or something which could allow this? Maybe if I got the user to type stty cbreak or stty raw before running telnet, this would work? (UNIX only, I know!) If I can get telnet to do this then it saves me having to write a special client just for this feature...

• Problem with jQuery animation

  - by Daemon

  I have a problem with an animation in jQuery using ajax. On the click of an button (actually an tag), I call a ajax method, and have the following written inside the success parameter: success: function(msg) { $('.ContentsMainRight').children().fadeOut(500, function() { $('.ContentsMainRight').html(msg.d); $('.ContentsMainRight').children().fadeIn(1000); }); }, This have the following result. The contents of a div fade out over 500ms as it's supposed to. Then the html contents of the div are swapped, but then the last part did not work as I hoped. The html returned by the ajax method include some text inside a tag, and a image inside a tag. The result is that the text is automatically displayed instantly with no fadein, but the img that is put fades in over 1 second. Why is the text and image treated differently? -Daemon

• Namespacing technique in JavaScript, recommended? performant? issues to be aware of?

  - by Bjartr

  In a project I am working on I am structuring my code as follows MyLib = { AField:0, ASubNamespace:{ AnotherField:"value", AClass:function(param) { this.classField = param; this.classFunction = function(){ // stuff } } }, AnotherClass:function(param) { this.classField = param; this.classFunction = function(){ // stuff } } } and so on like that to do stuff like: var anInstance = new MyLib.ASubNamespace.AClass("A parameter."); Is this the right way to go about achieving namespacing? Are there performance hits, and if so, how drastic? Do performance degradations stack as I nest deeper? Are there any other issues I should be aware of when using this structure? I care about every little bit of performance because it's a library for realtime graphics, so I'm taking any overhead very seriously.
