  • GWT: Wrong Key Codes generated with a French keyboard

    - by Flueras Bogdan
    On any french keyboard(AZERTY) the dot char '.' is generated with (Shift + ;) combination while the percent char '%' is generated with (Shift + ù) combination So when I type one of the above combinations in a GWT text area to write '.' or ' %', the key codes generated for these events are KEY_DELETE in the former case and KEY_LEFT in the latter. TextArea txtArea = new TextArea(); txtArea.addKeyPressHandler(new KeyPressHandler() { public void onKeyPress(KeyPressEvent event) { switch (charCode) { case KeyCodes.KEY_LEFT: { // key code 37 System.out.write("KEY LEFT"); break; } case KeyCodes.KEY_DELETE: { // key code 46 System.out.write("DELETE"); break; } } Workaround: get charCode and do a character match: charCode = event.getCharCode(); if (charCode == '.') {...} else if (charCode == '%') {...} Is this a GWT bug? And is there a more elegant way to handle this ?

  • insert or update on table violates foreign key constraint

    - by sprasad12
    Hi, I have two tables entitytype and project. Here are the create table statements: Create table project ( pname varchar(20) not null, primary key(pname) ); create table entitytype( entityname varchar(20) not null, toppos char(100), leftpos char(100), pname varchar(20) not null, primary key(entityname), foreign key(pname) references project(pname) on delete cascade on update cascade ); Now when i try to insert any values into entitytype table i am getting the following error: ERROR: insert or update on table "entitytype" violates foreign key constraint "entitytype_pname_fkey" Detail: Key (pname)=(494) is not present in table "project". Can someone please shed some light on what i am doing wrong. Any input will be of great help. Thank you.

  • Python objects as userdata in ctypes callback functions

    - by flight
    The C function myfunc operates on a larger chunk of data. The results are returned in chunks to a callback function: int myfunc(const char *data, int (*callback)(char *result, void *userdata), void *userdata); Using ctypes, it's no big deal to call myfunc from Python code, and to have the results being returned to a Python callback function. This callback work fine. myfunc = mylib.myfunc myfunc.restype = c_int myfuncFUNCTYPE = CFUNCTYPE(STRING, c_void_p) myfunc.argtypes = [POINTER(c_char), callbackFUNCTYPE, c_void_p] def mycb(result, userdata): print result return True input="A large chunk of data." myfunc(input, myfuncFUNCTYPE(mycb), 0) But, is there any way to give a Python object (say a list) as userdata to the callback function? In order to store away the result chunks, I'd like to do e.g.: def mycb(result, userdata): userdata.append(result) userdata=[] But I have no idea how to cast the Python list to a c_void_p, so that it can be used in the call to myfunc. My current workaround is to implement a linked list as a ctypes structure, which is quite cumbersome.

  • Haskell Parse Paragraph and em element with Parsec

    - by Martin
    I'm using Text.ParserCombinators.Parsec and Text.XHtml to parse an input like this: this is the beginning of the paragraph --this is an emphasized text-- and this is the end\n And my output should be: <p>this is the beginning of the paragraph <em>this is an emphasized text</em> and this is the end\n</p> This code parses and returns an emphasized element em = do{ ;count 2 (char '-') ; ;s <- manyTill anyChar (count 2 (char '-')) ;return (emphasize << s) } But I don't know how to get the paragraphs with emphasized items Any ideas? Thanks!!

  • Windows Service HTTPListener Memory Issue

    - by crawshaws
    Hi all, Im a complete novice to the "best practices" etc of writing in any code. I tend to just write it an if it works, why fix it. Well, this way of working is landing me in some hot water. I am writing a simple windows service to server a single webpage. (This service will be incorperated in to another project which monitors the services and some folders on a group of servers.) My problem is that whenever a request is recieved, the memory usage jumps up by a few K per request and keeps qoing up on every request. Now ive found that by putting GC.Collect in the mix it stops at a certain number but im sure its not meant to be used this way. I was wondering if i am missing something or not doing something i should to free up memory. Here is the code: Public Class SimpleWebService : Inherits ServiceBase 'Set the values for the different event log types. Public Const EVENT_ERROR As Integer = 1 Public Const EVENT_WARNING As Integer = 2 Public Const EVENT_INFORMATION As Integer = 4 Public listenerThread As Thread Dim HTTPListner As HttpListener Dim blnKeepAlive As Boolean = True Shared Sub Main() Dim ServicesToRun As ServiceBase() ServicesToRun = New ServiceBase() {New SimpleWebService()} ServiceBase.Run(ServicesToRun) End Sub Protected Overrides Sub OnStart(ByVal args As String()) If Not HttpListener.IsSupported Then CreateEventLogEntry("Windows XP SP2, Server 2003, or higher is required to " & "use the HttpListener class.") Me.Stop() End If Try listenerThread = New Thread(AddressOf ListenForConnections) listenerThread.Start() Catch ex As Exception CreateEventLogEntry(ex.Message) End Try End Sub Protected Overrides Sub OnStop() blnKeepAlive = False End Sub Private Sub CreateEventLogEntry(ByRef strEventContent As String) Dim sSource As String Dim sLog As String sSource = "Service1" sLog = "Application" If Not EventLog.SourceExists(sSource) Then EventLog.CreateEventSource(sSource, sLog) End If Dim ELog As New EventLog(sLog, ".", sSource) ELog.WriteEntry(strEventContent) End Sub Public Sub ListenForConnections() HTTPListner = New HttpListener HTTPListner.Prefixes.Add("http://*:1986/") HTTPListner.Start() Do While blnKeepAlive Dim ctx As HttpListenerContext = HTTPListner.GetContext() Dim HandlerThread As Thread = New Thread(AddressOf ProcessRequest) HandlerThread.Start(ctx) HandlerThread = Nothing Loop HTTPListner.Stop() End Sub Private Sub ProcessRequest(ByVal ctx As HttpListenerContext) Dim sb As StringBuilder = New StringBuilder sb.Append("<html><body><h1>Test My Service</h1>") sb.Append("</body></html>") Dim buffer() As Byte = Encoding.UTF8.GetBytes(sb.ToString) ctx.Response.ContentLength64 = buffer.Length ctx.Response.OutputStream.Write(buffer, 0, buffer.Length) ctx.Response.OutputStream.Close() ctx.Response.Close() sb = Nothing buffer = Nothing ctx = Nothing 'This line seems to keep the mem leak down 'System.GC.Collect() End Sub End Class Please feel free to critisise and tear the code apart but please BE KIND. I have admitted I dont tend to follow the best practice when it comes to coding.

  • Parse values from a text file in C

    - by Mohit Deshpande
    Say I have written to a text file in this format: key1/value1 key2/value2 akey/withavalue anotherkey/withanothervalue I have a linked list like: struct Node { char *key; char *value; struct Node *next; }; to hold the values. How would I read key1 and value1? I was thinking of putting line by line in a buffer and using strtok(buffer, '/'). Would that work? What other ways could work, maybe a bit faster or less prone to error? Please include a code sample if you can!

  • free() on stack memory

    - by vidicon
    I'm supporting some c code on Solaris, and I've seen something weird at least I think it is: char new_login[64]; ... strcpy(new_login, (char *)login); ... free(new_login); My understanding is that since the variable is a local array the memory comes from the stack and does not need to be freed, and moreover since no malloc/calloc/realloc was used the behaviour is undefined. This is a real-time system so I think it is a waste of cycles. Am I missing something obvious?

  • Serializing Python bytestrings to JSON, preserving ordinal character values

    - by Doctor J
    I have some binary data produced as base-256 bytestrings in Python (2.x). I need to read these into JavaScript, preserving the ordinal value of each byte (char) in the string. If you'll allow me to mix languages, I want to encode a string s in Python such that ord(s[i]) == s.charCodeAt(i) after I've read it back into JavaScript. The cleanest way to do this seems to be to serialize my Python strings to JSON. However, json.dump doesn't like my bytestrings, despite fiddling with the ensure_ascii and encoding parameters. Is there a way to encode bytestrings to Unicode strings that preserves ordinal character values? Otherwise I think I need to encode the characters above the ASCII range into JSON-style \u1234 escapes; but a codec like this does not seem to be among Python's codecs. Is there an easy way to serialize Python bytestrings to JSON, preserving char values, or do I need to write my own encoder?

  • Declaring data types in SQLite

    - by dan04
    I'm familiar with how type affinity works in SQLite: You can declare column types as anything you want, and all that matters is whether the type name contains "INT", "CHAR", "FLOA", etc. But is there a commonly-used convention on what type names to use? For example, if you have an integer column, is it better to distinguish between TINYINT, SMALLINT, MEDIUMINT, and BIGINT, or just declare everything as INTEGER? So far, I've been using the following: INTEGER REAL CHAR(n) -- for strings with a known fixed with VARCHAR(n) -- for strings with a known maximum width TEXT -- for all other strings BLOB BOOLEAN DATE -- string in "YYYY-MM-DD" format TIME -- string in "HH:MM:SS" format TIMESTAMP -- string in "YYYY-MM-DD HH:MM:SS" format (Note that the last three are contrary to the type affinity.)

  • Is this crash in libdispatch caused by Reachability?

    - by esilver
    Can anyone tell me if this crashing stack appears to be caused by Reachability? I am running apple's latest implementation of Reachability, downloadable at https://developer.apple.com/library/ios/samplecode/reachability/Introduction/Intro.html I have an app where ARC is not enabled by default (it is a legacy app) but I enable it on a per-file basis. I have enabled -fobjc-arc for Reachability.m When I look at these threads, my code is nowhere to be found. I see some activity happening because of a WebHTMLView (probably the ad network view code currently on screen; it's not mine). On Thread 10, I see a SCNetworkReachabilityDeallocate, then a dispatch_semaphore_wait_slow, and the crash happens on Thread 14 in libdispatch. Do you think this crash is being caused by that Reachability code, and have I erred in using -fobjc-arc with Reachability.m?

  • using WrapCompressedRTFStream in C#

  • Readline, the Input Record Separator and Ruby

    - by JustSmith
    In Ruby I'm looking to read data until I reach a delimiter or end of file. I found this is possible by redefining $/ or the $INPUT_RECORD_SEPARATOR to my delimiter. However with all the "features" in the Ruby language it seems hokey to change the value of a global to do this. Also, readline used to consume the delimiter while not it is included in what is returned. Is there any other way to "read until" while consuming the delimiter that doesn't involve getting the values char by char in a loop?

  • Linq help using "Contains"

    - by Kettenbach
    Good Morning All, I'm trying to use "Contains" to see if an object is within the collection. When I break I can see that the object is indeed part of the collection however "Contains" seems to be returning false indicating the item is not in the collection. Any idea what I'm doing wrong? if(HttpContext.Current.Session["AutoPayTypes"] != null) { var autopays = HttpContext.Current.Session["AutoPayTypes"] as List<PaymentTypeInfo>; char? coverageProductLine = null; if(entityProps.ContainsKey("CoverageProductLine")) { coverageProductLine = (char?)entityProps["CoverageProductLine"]; } var paymentTypeInfoRepository = new PaymentTypeInfoRepository(); var payType = paymentTypeInfoRepository.GetPaymentTypeInfo(paymentAdd.PayType, coverageProductLine); if (autopays != null && payType != null) paymentAdd.DaysPaid = autopays.Contains(payType) ? null : paymentAdd.DaysPaid; } If the object is not in the collection the "DaysPaid" needs to be null. Any ideas? Thanks, ~ck in San Diego

  • Convert "this" to a reference-to-pointer

    - by Austin Hyde
    Just stumbled onto this problem. (title says it all) Let's say I have a struct struct Foo { void bar () { do_baz(this); } void do_baz(Foo*& pFoo) { pFoo->p_sub_foo = new Foo; // for example } Foo* p_sub_foo; } GCC tells me that temp.cpp: In member function ‘void Foo::bar()’: temp.cpp:3: error: no matching function for call to ‘Foo::do_baz(Foo* const)’ temp.cpp:5: note: candidates are: void Foo::do_baz(Foo*&) So, how do I convert what is apparently a const Foo* to a Foo*&?

  • XML::LibXML Line Ending (whitespace) Problem.

    - by Gilbeg
    HI, I am parsing an XML file using LibXML in Perl. The problem that I have is the ending characters (whitespace) is treated as a text node. For instance, given an input like the following abc 123 The parser thinks that the number of child of node "books" is 3, they are: - text node (containing the char between and - element node of "book" - text node (containing the char between and Question is how do I tell LibXML to ignore whitespaces? I tried with no_blanks (that is $parser = XML::LibXML-new(no_blanks = 1) when construction the parser) but it seems that it has no effect. Thanks in advance

  • Using numeric_limits::max() in constant expressions

    - by FireAphis
    Hello, I would like to define inside a class a constant which value is the maximum possible int. Something like this: class A { ... static const int ERROR_VALUE = std::numeric_limits<int>::max(); ... } This declaration fails to compile with the following message: numeric.cpp:8: error: 'std::numeric_limits::max()' cannot appear in a constant-expression numeric.cpp:8: error: a function call cannot appear in a constant-expression I understand why this doesn't work, but two things look weird to me: It seems to me a natural decision to use the value in constant expressions. Why did the language designers decide to make max() a function thus not allowing this usage? The spec claims in 18.2.1 that For all members declared static const in the numeric_limits template, specializations shall define these values in such a way that they are usable as integral constant expressions. Doesn't it mean that I should be able to use it in my scenario and doesn't it contradict the error message? Thank you.

  • Inline & not-inline

    - by anon
    Suppose I have: struct Vec3 { double x; double y; double z; } ; inline double dot(const Vec3& lhs, const Vec3& rhs) { return lhs.x * rhs.x + lhs.y * rhs.y + lhs.z * rhs.z ; } Is it possible to have "dot" also exist in a non-inlined version, so that it can be in the *.so , so that when I dl open it I can call it? I.e. I want files that include the above header to use the inlined version, but I also want the function to exist in a *.so, so I can dl open it and call it dynamically.

  • Sys undefined for HTTPS url in IE8

    - by Dhana
    I just discovered a rather peculiar issue in IE8 for a HTTPS link. Every time the page tries to access the HTTPS link, it produces an error. This happens only in IE8 and nothing else. Any idea what's going on? I found some items that said that means the files were not loaded, hence the issue and tried some fixes recommended, but they haven't worked so far. This is a .NET site by the way. https://www.beckshoes.com/cart/cart.aspx Message: 'Sys' is undefined Line: 70 Char: 1 Code: 0 URI: https://www.beckshoes.com/cart/cart.aspx Message: 'Sys' is undefined Line: 319 Char: 1 Code: 0 URI: https://www.beckshoes.com/cart/cart.aspx

  • MySQL unique clustered constraint not constraining as expected

    - by igor
    I'm creating a table with: CREATE TABLE movies ( id INT AUTO_INCREMENT PRIMARY KEY, name CHAR(255) NOT NULL, year INT NOT NULL, inyear CHAR(10), CONSTRAINT UNIQUE CLUSTERED (name, year, inyear) ); (this is jdbc SQL) Which creates a MySQL table with a clustered index, "index kind" is "unique", and spans the three clustered columns: full size However, once I dump my data (without exceptions thrown), I see that the uniqueness constraint has failed: SELECT * FROM movies WHERE name = 'Flawless' AND year = 2007 AND inyear IS NULL; gives: id, name, year, inyear 162169, 'Flawless', 2007, NULL 162170, 'Flawless', 2007, NULL Does anyone know what I'm doing wrong here?
