• Unknown Exception on trying to initialize the web service stub created by Axis C++

  - by Harsha Reddy

  Hi, I am trying out the sample calculator program given in the folder of axis c++. I am mainly interested in the client side. So I used the wsdl to create the stubs and my main is pretty much the same as given in the sample. However on executing the call Calculator ws (endpoint) I get an unknown exception "First-chance exception at 0x7c0024b9 in CalculatorClient.exe: 0xC0000005: Access violation reading location 0x00000000. First-chance exception at 0x7c812afb in CalculatorClient.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000.. Unhandled exception at 0x7c0024b9 in CalculatorClient.exe: 0xC0000005: Access violation reading location 0x00000000." and the exception causing code is Calculator::Calculator(const char* pchEndpointUri, AXIS_PROTOCOL_TYPE eProtocol) :Stub(pchEndpointUri, eProtocol) { } I had earlier tried to run a a webservice using Axis C++ but had received the same error. At that time my web service was a java ws on WAS. Then I later tried the calculator client (but this time I did not have any server hosting the ws as I just wanted to check if the Client could initialize). Is the problem caused due to the web service not being hosted on Apache in C++ (though I highly doubt it). Any help would be appreciated. Thanks, Harsha

• Exception during iteration on collection and remove items from that collection

  - by Muhammad Kashif Nadeem

  I remove item from ArrayList in foreach loop and get follwing exception. Collection was modified; enumeration operation may not execute. How can I remove items in foreach Following is my code: /* * Need to remove all items from 'attachementsFielPath' which does not exist in names array. */ try { string attachmentFileNames = txtAttachment.Text.Trim(); // Textbox having file names. string[] names = attachmentFileNames.Split(new char[] { ';' }); int index = 0; // attachmentsFilePath is ArrayList holding full path of fiels user selected at any time. foreach (var fullFilePath in attachmentsFilePath) { bool isNeedToRemove = true; // Extract filename from full path. string fileName = fullFilePath.ToString().Substring(fullFilePath.ToString().LastIndexOf('\\') + 1); for (int i = 0; i < names.Length; i++) { // If filename found in array then no need to check remaining items. if (fileName.Equals(names[i].Trim())) { isNeedToRemove = false; break; } } // If file not found in names array, remove it. if (isNeedToRemove) { attachmentsFilePath.RemoveAt(index); isNeedToRemove = true; } index++; } } catch (Exception ex) { throw ex; }

• how to find the height of html content

  - by ganapati hegde

  Hi, I am trying to display 10 html pages as a single document,with 10 chapters. I am using Webkitgtk+ engine to render the HTML pages. I am getting the content of each html files and concatenating all of them to create a single 'char *content' and using webkit_web_view_load_html_string(WebKitWebView *web_view, const gchar *content, const gchar *base_uri); this function to load all the HTML files, as a document. Now i am trying to build a 'table of contents(toc)' for this document, which displays all the chapter names in order. My requirement is, when i click on a particular chapter in toc, the document should scroll to that point. For that i need to know height of each chapter ( height of each html file content). The point to be noted here is, the width of the document can changed and as HTML is reflowable, as width increases height decreases and vice-versa. So each time when height changes i need to find out the current height of each HTML page(or chapter) and hence calculate the distance to be scrolled. How can i find out the height of content of HTML page dynamically ? Thank you for the answer....

• Weird switch behavior in .NET 4

  - by RaYell

  I have a problem understanding what's causes the compilation error in the code below: static class Program { static void Main() { dynamic x = ""; var test = foo(x); if (test == "test") { Console.WriteLine(test); } switch (test) { case "test": Console.WriteLine(test); break; } } private static string foo(object item) { return "bar"; } } The error I get is in switch (test) line: A switch expression or case label must be a bool, char, string, integral, enum, or corresponding nullable type. Intellisence shows me that foo operation will be resolved on runtime, which is fine because I'm using a dynamic type as a param. However I don't understand how if condition compiles fine when switch doesn't. Code above is just simplified version of what I have in my application (VSTO) which appeared after migrating the app from VSTO3 to VSTO4 when one method in VSTO was changed to return dynamic type values instead of object. Can anyone give me an explanation what's the problem. I know how to resolve it but I'd like to understand what's happening.

• sqlite3 no insert is done after --> insert into --> SQLITE_DONE

  - by Fra

  Hi all, I'm trying to insert some data in a table using sqlite3 on an iphone... All the error codes I get from the various steps indicate that the operation should have been successful, but in fact, the table remains empty...I think I'm missing something... here the code: sqlite3 *database = nil; NSString *dbPath = [[[ NSBundle mainBundle ] resourcePath ] stringByAppendingPathComponent:@"placemarks.sql"]; if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK){ sqlite3_stmt *insert_statement = nil; //where int pk, varchar name,varchar description, blob picture static char *sql = "INSERT INTO placemarks (pk, name, description, picture) VALUES(99,'nnnooooo','dddooooo', '');"; if (sqlite3_prepare_v2(database, sql, -1, &insert_statement, NULL) != SQLITE_OK) { NSAssert1(0, @"Error: failed to prepare statement with message '%s'.", sqlite3_errmsg(database)); } int success = sqlite3_step(insert_statement); int finalized = sqlite3_finalize(insert_statement); NSLog(@"success: %i finalized: %i",success, finalized); NSAssert1(101, @"Error: failed to insert into the database with message '%s'.", sqlite3_errmsg(database)); sqlit3_step returns 101, so SQLITE_DONE, which should be ok.. If I execute the sql statement in the command line it works properly... anyone has an idea? could it be that there's a problem in writing the placemarks.sql because it's in the resources folder? rgds Fra

• string parsing to double fails in C++ (Xcode problem?)

  - by helixed

  Here's a fun one I've been trying to figure out. I have the following program: #include <iostream> #include <string> #include <sstream> using namespace std; int main(int argc, char *argv[]) { string s("5"); istringstream stream(s); double theValue; stream >> theValue; cout << theValue << endl; cout << stream.fail(); } The output is: 0 1 I don't understand why this is failing. Could somebody please tell me what I'm doing wrong? Thanks, helixed EDIT: Okay, sorry to turn this into a double post, but this looks like a problem specific to Xcode. If I compile this in g++, the code works without a problem. Does anybody have an idea why this is happening in Xcode, and how I could possibly fix it? Thanks again, helixed

• Why is Swing Parser's handleText not handling nested tags?

  - by Jim P

  I need to transform some HTML text that has nested tags to decorate 'matches' with a css attribute to highlight it (like firefox search). I can't just do a simple replace (think if user searched for "img" for example), so I'm trying to just do the replace within the body text (not on tag attributes). I have a pretty straightforward HTML parser that I think should do this: final Pattern pat = Pattern.compile(srch, Pattern.CASE_INSENSITIVE); Matcher m = pat.matcher(output); if (m.find()) { final StringBuffer ret = new StringBuffer(output.length()+100); lastPos=0; try { new ParserDelegator().parse(new StringReader(output.toString()), new HTMLEditorKit.ParserCallback () { public void handleText(char[] data, int pos) { ret.append(output.subSequence(lastPos, pos)); Matcher m = pat.matcher(new String(data)); ret.append(m.replaceAll("<span class=\"search\">$0</span>")); lastPos=pos+data.length; } }, false); ret.append(output.subSequence(lastPos, output.length())); return ret; } catch (Exception e) { return output; } } return output; My problem is, when I debug this, the handleText is getting called with text that includes tags! It's like it's only going one level deep. Anyone know why? Is there some simple thing I need to do to HTMLParser (haven't used it much) to enable 'proper' behavior of nested tags? PS - I figured it out myself - see answer below. Short answer is, it works fine if you pass it HTML, not pre-escaped HTML. Doh! Hope this helps someone else. <span>example with <a href="#">nested</a> <p>more nesting</p> </span> <!-- all this gets thrown together -->

• Simple Java calculator

  - by Kevin Duke

  Firstly this is not a homework question. I am practicing my knowledge on java. I figured a good way to do this is to write a simple program without help. Unfortunately, my compiler is telling me errors I don't know how to fix. Without changing much logic and code, could someone kindly point out where some of my errors are? Thanks import java.lang.*; import java.util.*; public class Calculator { private int solution; private int x; private int y; private char operators; public Calculator() { solution = 0; Scanner operators = new Scanner(System.in); Scanner operands = new Scanner(System.in); } public int addition(int x, int y) { return x + y; } public int subtraction(int x, int y) { return x - y; } public int multiplication(int x, int y) { return x * y; } public int division(int x, int y) { solution = x / y; return solution; } public void main (String[] args) { System.out.println("What operation?

• how i print the values from NSArray objects in CGContextShowTextAtpoint()?

  - by Rajendra Bhole

  Hi, I developing an application in which i want to print the values on a line interval, for that i used NSArray with multiple objects and those object i passing into CGContextShowTextAtPoint() method. The code is. CGContextMoveToPoint(ctx, 30.0, 200.0); CGContextAddLineToPoint(ctx, 30.0, 440.0); NSArray *hoursInDays = [[NSArray alloc] initWithObjects:@"0",@"1",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10",@"11",@"12", nil]; int intHoursInDays = 0; for(float y = 400.0; y >= 200.0; y-=18, intHoursInDays++) { CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextMoveToPoint(ctx, 28, y); CGContextAddLineToPoint(ctx, 32, y); CGContextSelectFont(ctx, "Helvetica", 12.0, kCGEncodingMacRoman); CGContextSetTextDrawingMode(ctx, kCGTextFill); CGContextSetRGBFillColor(ctx, 0, 255, 255, 1); CGAffineTransform xform = CGAffineTransformMake( 1.0, 0.0, 0.0, -1.0, 0.0, 0.0); CGContextSetTextMatrix(ctx, xform); NSString *arrayDataForYAxis = [hoursInDays objectAtIndex:intHoursInDays]; CGContextShowTextAtPoint(ctx, 10.0, y+20, [arrayDataForYAxis UTF8String], strlen((char *)arrayDataForYAxis)); CGContextStrokePath(ctx); } The above code is executed but it given me output is {oo, 1o,2o,...........11}, i want the output is {0,1,2,3...........11,12}. The above code given me one extra character "o" after single digit.I think the problem i meet near the parameters type casting of 5th parameter inside the method of CGContextShowTextAtpoint CGContextShowTextAtpoint(). How i resolve the problem of type casting for printing the objects of NSSArray in CGContextShowTextAtpoint() method??????????????

• Non-blocking TCP buffer issues.

  - by Poni

  Hi! I think I'm in a problem. I have two TCP apps connected to each other which use winsock I/O completion ports to send/receive data (non-blocking sockets). Everything works just fine until there's a data transfer burst. The sender starts sending incorrect/malformed data. I allocate the buffers I'm sending on the stack, and if I understand correctly, that's a wrong to do, because these buffers should remain as I sent them until I get the "write complete" notification from IOCP. Take this for example: void some_function() { char cBuff[1024]; // filling cBuff with some data WSASend(...); // sending cBuff, non-blocking mode // filling cBuff with other data WSASend(...); // again, sending cBuff // ..... and so forth! } If I understand correctly, each of these WSASend() calls should have its own unique buffer, and that buffer can be reused only when the send completes. Correct? Now, what strategies can I implement in order to maintain a big sack of such buffers, how should I handle them, how can I avoid performance penalty, etc'? And, if I am to use buffers that means I should copy the data to be sent from the source buffer to the temporary one, thus, I'd set SO_SNDBUF on each socket to zero, so the system will not re-copy what I already copied. Are you with me? Please let me know if I wasn't clear.

• jQuery and XHTML layout problems in ie7

  - by abysslogic

  Hi there, I am back again with more layout problems on my up and coming website. I am able to achieve the proper animation, positioning and results with my layout / splash on every modern browser (excluding ie7 or older). I have an image in the center of the page, that is text-align: center'd, and pushed to a vertical center by having a div (#SPLASH_HEAD) set to 50% on the top half of the page. The loading animation changes the height of #SPLASH_HEAD to 0px, to drag the image to the top (and then do other things). In ie7 (or compatability mode), it appears that there is an error in jquery-1.4.2.min.js, line 116 char 165 (which I dont think has anything to do with the actual jQuery file itself). The splash is not centered either vertically (#SPLASH_HEAD does not register at 50% of window height) and is not centered properly with margin-left. Also, none of the other elements are hidden properly (with .hide()) as ie7 does not appear to be loading all of my jQuery / javascript. heres a link: www.voidsync.com/test (it would be easier to view the source on there) thanks!

• PIC C - USB_CDC_GETC() and retrieving strings.

  - by Adam

  Hi all, I'm programming a PIC18F4455 Microcontroller using PIC C. I'm using the USB_CDC.h header file. I have a program on the computer sending a string such as "W250025". However, when I use usb_cdc_getc() to get the first char, it freezes. Sometimes the program sends only 'T', so I really want to just get the first character. Why does my code never execute past received=usb_cdc_getc(); when I send "W250025"? if (usb_cdc_kbhit()) { //printf(lcd_putc, "Check 3"); delay_ms(3000); printf(lcd_putc, "\f"); received = usb_cdc_getc(); printf(lcd_putc, "Received "); lcd_putc(received); delay_ms(3000); printf(lcd_putc, "\f"); if (received == 'W'){ //waveform disable_interrupts(INT_TIMER1); set_adc_channel(0); load_and_print_array(read_into_int(), read_into_int());} else if (received == 'T'){ //temperature set_adc_channel(1); enable_interrupts(INT_TIMER1);} }

• VERY simple C program won't compile with VC 64

  Here is a very simple C program: #include <stdio.h> int main (int argc, char *argv[]) { printf("sizeof(short) = %d\n",(int)sizeof(short)); printf("sizeof(int) = %d\n",(int)sizeof(int)); printf("sizeof(long) = %d\n",(int)sizeof(long)); printf("sizeof(long long) = %d\n",(int)sizeof(long long)); printf("sizeof(float) = %d\n",(int)sizeof(float)); printf("sizeof(double) = %d\n",(int)sizeof(double)); return 0; } While it compiles fine on Win32 (command line: cl main.c), it does not using the Win64 compiler ("c:\Program Files(x86)\Microsoft Visual Studio 9.0\VC\bin\amd64\cl.exe" main.c). Specifically, it sais "error LNK2019: unresolved external symbol printf referenced in function main". As far as I understand this, it can not link to printf, right? Obviously, I have Microsoft Visual C++ Compiler 2008 (Standard enu) x86 and x64 installed and am using the 64-bit flavor of Windows (7). What is the problem here?

• Convert function to read from string instead of file in C

  - by Dusty

  I've been tasked with updating a function which currently reads in a configuration file from disk and populates a structure: static int LoadFromFile(FILE *Stream, ConfigStructure *cs) { int tempInt; ... if ( fscanf( Stream, "Version: %d\n",&tempInt) != 1 ) { printf("Unable to read version number\n"); return 0; } cs->Version = tempInt; ... } to one which allows us to bypass writing the configuration to disk and instead pass it directly in memory, roughly equivalent to this: static int LoadFromString(char *Stream, ConfigStructure *cs) A few things to note: The current LoadFromFile function is incredibly dense and complex, reading dozens of versions of the config file in a backward compatible manner, which makes duplication of the overall logic quite a pain. The functions that generate the config file and those that read it originate in totally different parts of the old system and therefore don't share any data structures so I can't pass those directly. I could potentially write a wrapper, but again, it would need to handle any structure passed in in a backwards compatible manner. I'm tempted to just pass the file as is in as a string (as in the prototype above) and convert all the fscanf's to sscanf's but then I have to handle incrementing the pointer along (and potentially dealing with buffer overrun errors) manually. This has to remain in C, so no C++ functionality like streams can help here Am I missing a better option? Is there some way to create a FILE * that actually just points to a location in memory instead of on disk? Any pointers, suggestions or other help is greatly appreciated.

• Help me find an appropriate ruby/python parser generator

  - by Geo

  The first parser generator I've worked with was Parse::RecDescent, and the guides/tutorials available for it were great, but the most useful feature it has was it's debugging tools, specifically the tracing capabilities ( activated by setting $RD_TRACE to 1 ). I am looking for a parser generator that can help you debug it's rules. The thing is, it has to be written in python or in ruby, and have a verbose mode/trace mode or very helpful debugging techniques. Does anyone know such a parser generator ? EDIT: when I said debugging, I wasn't referring to debugging python or ruby. I was referring to debugging the parser generator, see what it's doing at every step, see every char it's reading, rules it's trying to match. Hope you get the point. BOUNTY EDIT: to win the bounty, please show a parser generator framework, and illustrate some of it's debugging features. I repeat, I'm not interested in pdb, but in parser's debugging framework. Also, please don't mention treetop. I'm not interested in it.

It is intended to spell check the word "and" using state to state transition. include include using namespace std; string in_str; int n; void spell_check() { int i; FILE *in_file; while (!EOF(in_file)) { fscanf(in_str); n = strlen(in_str); start(in_str,n); } } void start() { char next_char; int i = 0; if (n == 0) { cout<<"This is an empty string"; exit();//do something here to terminate the program } else{ next_char = in_str[i]; if(next_char == 'a') { i++; if(i >= n) error(); else state_A(i); } else error(); } } void state_A(int i) { if(in_str[i] == 'n') { i++; if(i void state_AN(int i) { if(in_str[i] == 'd') { if(i == n-1) cout<<" Your keyword spelling is correct"; else cout<<"Wrong keyword spelling"; } } int main() { spell_check(); return 0; }

• Trouble creating a Java policy server for a simple Flash app

  - by simonwulf

  I'm trying to create a simple Flash chat application for educational purposes, but I'm stuck trying to send a policy file from my Java server to the Flash app (after several hours of googling with little luck). The policy file request reaches the server that sends a harcoded policy xml back to the app, but the Flash app doesn't seem to react to it at all until it gives me a security sandbox error. I'm loading the policy file using the following code in the client: Security.loadPolicyFile("xmlsocket://myhostname:" + PORT); The server recognizes the request as "<policy-file-request/" and responds by sending the following xml string to the client: public static final String POLICY_XML = "<?xml version=\"1.0\"?>" + "<cross-domain-policy>" + "<allow-access-from domain=\"*\" to-ports=\"*\" />" + "</cross-domain-policy>"; The code used to send it looks like this: try { _dataOut.write(PolicyServer.POLICY_XML + (char)0x00); _dataOut.flush(); System.out.println("Policy sent to client: " + PolicyServer.POLICY_XML); } catch (Exception e) { trace(e); } Did I mess something up with the xml or is there something else I might have overlooked?

• 'strcpy' error and warning

  - by Leejo

  I'm getting a 'strcpy' error and warning for the following lines: _tcscpy(strCommandLine,_T("MyProgram.exe /param1")); _tcscpy(strApplicationName,_T("MyProgram.exe")); Not sure why I'm getting a 'strcpy' error or warning since I'm not using 'strcpy'. The only lines related to this is: LPCTSTR strApplicationName; LPTSTR strCommandLine; _tcscpy(strCommandLine,_T("MyProgram.exe /param1")); //warning is on this line _tcscpy(strApplicationName,_T("MyProgram.exe")); //error is on this line The output is: 1c:\documents and settings\X.X\my documents\sandbox\sample.cpp(52) : warning C4996: 'strcpy': This function or variable may be unsafe. Consider using strcpy_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details. 1 c:\program files\microsoft visual studio 8\vc\include\string.h(74) : see declaration of 'strcpy' 1c:\documents and settings\X.X\my documents\sandbox\sample.cpp(53) : error C2664: 'strcpy' : cannot convert parameter 1 from 'LPCTSTR' to 'char *' 1 Conversion loses qualifiers Any ideas on what this could means?

• Singleton with inheritance, Derived class is not able to get instantiated in parent?

  - by yesraaj

  Below code instantiates a derived singleton object based on environment variable. The compiler errors saying error C2512: 'Dotted' : no appropriate default constructor. I don't understand what the compiler is complaining about. #include <stdlib.h> #include <iostream> #include <string> using namespace std; class Dotted; class Singleton{ public: static Singleton instant(){ if (!instance_) { char * style = getenv("STYLE"); if (!style){ if (strcmp(style,"dotted")==0) { instance_ = new Dotted(); return *instance_; } } else{ instance_ = new Singleton(); return *instance_; } } return *instance_; } void print(){cout<<"Singleton";} ~Singleton(){}; protected: Singleton(){}; private: static Singleton * instance_; Singleton(const Singleton & ); void operator=(const Singleton & ); }; class Dotted:public Singleton{ public: void print(){cout<<"Dotted";} protected: Dotted(); }; Dotted::Dotted():Singleton(){} int main(){ Singleton::instant().print(); cin.get(); }

• Filtering Wikipedia's XML dump: error on some accents

  - by streetpc

  I'm trying to index Wikpedia dumps. My SAX parser make Article objects for the XML with only the fields I care about, then send it to my ArticleSink, which produces Lucene Documents. I want to filter special/meta pages like those prefixed with Category: or Wikipedia:, so I made an array of those prefixes and test the title of each page against this array in my ArticleSink, using article.getTitle.startsWith(prefix). In English, everything works fine, I get a Lucene index with all the pages except for the matching prefixes. In French, the prefixes with no accent also work (i.e. filter the corresponding pages), some of the accented prefixes don't work at all (like Catégorie:), and some work most of the time but fail on some pages (like Wikipédia:) but I cannot see any difference between the corresponding lines (in less). I can't really inspect all the differences in the file because of its size (5 GB), but it looks like a correct UTF-8 XML. If I take a portion of the file using grep or head, the accents are correct (even on the incriminated pages, the <title>Catégorie:something</title> is correctly displayed by grep). On the other hand, when I rectreate a wiki XML by tail/head-cutting the original file, the same page (here Catégorie:Rock par ville) gets filtered in the small file, not in the original… Any idea ? Alternatives I tried: Getting the file (commented lines were tried wihtout success): FileInputStream fis = new FileInputStream(new File(xmlFileName)); //ReaderInputStream ris = ReaderInputStream.forceEncodingInputStream(fis, "UTF-8" ); //(custom function opening the stream, reading it as UFT-8 into a Reader and returning another byte stream) //InputSource is = new InputSource( fis ); is.setEncoding("UTF-8"); parser.parse(fis, handler); Filtered prefixes: ignoredPrefix = new String[] {"Catégorie:", "Modèle:", "Wikipédia:", "Cat\uFFFDgorie:", "Mod\uFFFDle:", "Wikip\uFFFDdia:", //invalid char "Catégorie:", "Modèle:", "Wikipédia:", // UTF-8 as ISO-8859-1 "Image:", "Portail:", "Fichier:", "Aide:", "Projet:"}; // those last always work
