C++ and Scripting.Dictionary from scrrun.dll

- by MaxFX

Hello. I have some trouble with Scripting.Dictionary in C++. I'm trying to use interface IDictionary via smart pointer but methods of creating object don't work and I can't understand why. CoInitialize(NULL); IDictionaryPtr dict; dict.CreateInstance(__uuidof(Dictionary)); _variant_t num1 = 1; _variant_t num2 = 2; dict->Add(&num1, &num2); long i; dict->get_Count(&i); cout << i << "\n"; But method Add does not work and cout of elements in dictionary is always 0. How correct to use Scripting.Dictionary in that case. PS.: I'm getting Scripting interfaces by #import "scrrun.dll"

Does the WCF framework support the XSD IDREF restriction?

- by Gerard

A nice feature in XSD is the IDREF restriction, e.g.: <xs:restriction base="xs:IDREF"> <xs:pattern value="[0-9a-zA-Z\-]+"/> </xs:restriction> I used this restriction with great benefit in a Java JAXWS-project. An object serialized in a SOAP XML datamodel can hold a reference (pointer) to another object in the same SOAP message. I want to try the same approach in a C# WCF-project, can it be done? On the web site Data Contract Schema Reference I can see e.g. Id ignored, Ref forbidden, but I am not sure whether I understand what that means.

setting value to the instance of primitive types

- by Samreen

I have a function which performs some operation i.e. fetches some data from database. The generic it takes is primitive type always i.e. int, char, bool, string etc. I can easily create its instance. But I can't set the value that I have fetched from database to this instance. public T PerformOperation<T>() { object instance = (T)Activator.CreateInstance(typeof(T)); object result=FetchData(); instance = (T)result; //It gives error on this statement } The function is called as: int result = PerformOperation<int>(); Is there some way of casting the object Type to any generic type which is always primitive?

3 hash functions to best hash sliding window strings for a bloom filter with minimum collisions

- by Duaa

Hi all: I need 3 hash functions to hash strings of a sliding window moving over a text, to be used later to search within a bloom vector. I'm using C# in my programming I read something about rolling hash functions and cyclic polynomials, they are used for sliding window applications. But really, I did not find any codes, they are just descriptions So please, if anyone have any idea about 3 best C# hash functions to use with sliding window strings of fixed size (5-char), that consume less time and have minimum number of collisions, either they are rolling hash functions or others, please help me with some C# codes or links to hash functions names Duaa

What is a practical, real world example of the Linked List?

- by JStims

I understand the definition of a Linked List, but how can it be represented and related to a common concept or item? For example, inheritance in OOP can be related to automobiles. All (most) automobiles in real life are the essentially same thing; an automobile has an Engine, you can start() it, you can make the car go(), stop() and so on. An automobile would typically have a maximum passenger capacity but it would differ between a Bus and a SportsCar, which are both automobiles. Is there some real life, intuitive example of the plain ole' singly Linked List like we have with inheritance? The typical textbook Linked List example shows a node with an integer and a pointer to the next, and it just doesn't seem very useful. Your input is appreciated.

Pass a Delphi class to a C++ function/method that expects a class with __thiscall methods.

- by Alan G.

I have some MSVC++ compiled DLL's for which I have created COM-like (lite) interfaces (abstract Delphi classes). Some of those classes have methods that need pointers to objects. These C++ methods are declared with the __thiscall calling convention (which I cannot change), which is just like __stdcall, except a this pointer is passed on the ECX register. I create the class instance in Delphi, then pass it on to the C++ method. I can set breakpoints in Delphi and see it hitting the exposed __stdcall methods in my Delphi class, but soon I get a STATUS_STACK_BUFFER_OVERRUN and the app has to exit. Is it possible to emulate/deal with __thiscall on the Delphi side of things? If I pass an object instantiated by the C++ system then all is good, and that object's methods are called (as would be expected), but this is useless - I need to pass Delphi objects. Edit 2010-04-19 18:12 This is what happens in more detail: The first method called (setLabel) exits with no error (though its a stub method). The second method called (init), enters then dies when it attempts to read the vol parameter. C++ Side #define SHAPES_EXPORT __declspec(dllexport) // just to show the value class SHAPES_EXPORT CBox { public: virtual ~CBox() {} virtual void init(double volume) = 0; virtual void grow(double amount) = 0; virtual void shrink(double amount) = 0; virtual void setID(int ID = 0) = 0; virtual void setLabel(const char* text) = 0; }; Delphi Side IBox = class public procedure destroyBox; virtual; stdcall; abstract; procedure init(vol: Double); virtual; stdcall; abstract; procedure grow(amount: Double); virtual; stdcall; abstract; procedure shrink(amount: Double); virtual; stdcall; abstract; procedure setID(val: Integer); virtual; stdcall; abstract; procedure setLabel(text: PChar); virtual; stdcall; abstract; end; TMyBox = class(IBox) protected FVolume: Double; FID: Integer; FLabel: String; // public constructor Create; destructor Destroy; override; // BEGIN Virtual Method implementation procedure destroyBox; override; stdcall; // empty - Dont need/want C++ to manage my Delphi objects, just call their methods procedure init(vol: Double); override; stdcall; // FVolume := vol; procedure grow(amount: Double); override; stdcall; // Inc(FVolume, amount); procedure shrink(amount: Double); override; stdcall; // Dec(FVolume, amount); procedure setID(val: Integer); override; stdcall; // FID := val; procedure setLabel(text: PChar); override; stdcall; // Stub method; empty. // END Virtual Method implementation property Volume: Double read FVolume; property ID: Integer read FID; property Label: String read FLabel; end; I would have half expected using stdcall alone to work, but something is messing up, not sure what, perhaps something to do with the ECX register being used? Help would be greatly appreciated. Edit 2010-04-19 17:42 Could it be that the ECX register needs to be preserved on entry and restored once the function exits? Is the this pointer required by C++? I'm probably just reaching at the moment based on some intense Google searches. I found something related, but it seems to be dealing with the reverse of this issue.

Alternative to c++ static virtual methods

- by Jaime Pardos

In C++ is not possible to declare a static virtual function, neither cast a non-static function to a C style function pointer. Now, I have a plain ol' C SDK that uses function pointers heavily. I have to fill a structure with several function pointers. I was planning to use an abstract class with a bunch of static pure virtual methods, and redefine them in derived classes and fill the structure with them. It wasn't until then that I realized that static virtual are not allowed in C++. Is there any good alternative? The best I can think of is defining some pure virtual methods GetFuncA(), GetFuncB(),... and some static members FuncA()/FuncB() in each derived class, which would be returned by the GetFuncX(). Then a function in the abstract class would call those functions to get the pointers and fill the structure.

generic async loading method for page web scripts?

- by boomhauer

The google analytics code went to an async load model some time back. I've noticed that a lot of the other scripts I use on many sites are causing slow load times - specifically the addthis script and the facebook like button. I'm noticing that the slow load times of these scripts is causing the google bot to calc my page loadtimes as being much slower than previously. I'd like to know if there is a standard/generic way of causing these scripts to load async as well, or perhaps a pointer to someone who has done the work for this already. Seems this would be a popular thing to do, but not much luck searching around.

How to terminate process using VBScript

- by Mark

Hi, I have this VBScript code to terminate one process Const strComputer = "." Dim objWMIService, colProcessList Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2") Set colProcessList = objWMIService.ExecQuery("SELECT * FROM Win32_Process WHERE Name = 'Process.exe'") For Each objProcess in colProcessList objProcess.Terminate() Next it works fine with some processes, but when it comes to any process runs under SYSTEM, it can't stop it. Is there is anything I need to add to kill the process under SYSTEM? Thanks

Place an object on top of stack in ILGenerator

- by KiNGPiN

I have to pass a function an instance of an object, so obviously all the information to be taken as argument is to be loaded onto the evaluation stack Here is the code that i am looking for someClass SomeObject = new someClass(); il.Emit(OpCodes.LoadObject, SomeObject); il.Emit(OpCodes.CallVirt, MethodInfo Function); public void Function(Object obj) { Type type = typeof(obj); //do something w.r.t to the type } I dont require any information stored in the class just the type and i cannot use any of the primitive types to take my decision on Last i read that i can use a pointer to load the type using some opcodes ... but i am completely lost here, any help or pointers to the right direction would be great :)

ShellExecute not working from IDE but works otherwise.

- by Altar

I want to create and then open a txt file using the ShellExecute command. I have used this code for years with Delphi 7 and it worked: function Executa(CONST ExeName, Parameters: string): Boolean; begin if Parameters= '' then Result:= ShellExecute(0, 'open', PChar(ExeName), NIL , nil, SW_SHOWNORMAL)> 32 else Result:= ShellExecute(0, 'open', PChar(ExeName), PChar(Parameters), nil, SW_SHOWNORMAL)> 32; end; Now, I switch to Windows 7 (don't like it; they stuck it on my throat with my new laptop) 64 bit and the code is not working anymore when it runs from IDE. Delhi shows the CPU window with the caption "CPU-Process unknown (2352)". I close the CU windows and everything works fine until I close the application, when Delphi shows the CPU window one more time. If I run the app from outside IDE, it works fine. Looks like the debugger has something to say to me, but I don't know what.

Strange beep when using cout

- by Unknown

Hello everyone, today when I was working on some code of mine I came across a beeping sound when printing a buffer to the screen. Here's the mysterious character that produces the beep: '' I don't know if you can see it, but my computer beeps when I try to print it like this: cout<<(char)7<<endl; Another point of interest is that the 'beep' doesn't originate from my on board beeper, but from my headphone/speaker Is this just my computer or there something wrong with the cout function? EDIT: But then why does printing this character produce the beep sound? does that mean that I could send other such characters through the cout function to produce different effects?

how does fgets internally works?

- by Registered User

Well it is a basic question but I seem confused enough. #include<stdio.h> int main() { char a[100]; printf("Enter a string\n"); scanf("%s",a); } Basically the above is what I want to achieve. If I enter a string James Bond then I want that to be stored in array a. But the problem is because of presence of a blank space in between only James word is stored. So how can I solve this one. UPDATE After the replies given below I understand fgets() would be a better choice. I want to know internal working of fgets as why is it able to store the string with space where as scanf is not able to do the same.

How can I tell NetBeans to use the latest available version of a JAR for a library?

- by Freiheit

I have a Netbeans project with a library defined which includes several JARs. These JARs are versioned like lib\blah\com.blah.wibble.jar_0.6.1.201004161543 . These are nightly builds from another project so that version changes often. I know I can point NetBeans at the specific JARs with the version name, but this means that every time I get a new version I have to update the NetBeans library. I can also strip the version name from the JARs, but this makes it hard to track down bugs. "What version of the blah JARs?" is usually the second thing we ask when we find a bug. Is it possible to tell Netbeans to use included com.blah.wibble.jar_[??????] where ???? is some sort of automatic pointer to use the latest available version?

Implement the Combine function using templates

any idea on how to do it for template? thanks Implement the Combine function using templates. The Combine fn applies a function of two arguments cumulatively to the items of an STL container, from begin() to end(), so as to reduce the sequence to a single value. For example, Combine(<list containing 6,3,1,9,7>, std::plus<int>()) should calculate ((((6+3)+1)+9)+7). class NotEnoughElements {}; template <typename Container, typename Function> typename Container::value_type Combine(const Container& c, Function fn) throw (NotEnoughElements) { your code goes here }

NSData to display as a string

- by topace

Hello all, this is my first post. I am building an iPhone app and stuck with the following: unsigned char hashedChars[32]; CC_SHA256([inputString UTF8String], [inputString lengthOfBytesUsingEncoding:NSASCIIStringEncoding], hashedChars); NSData *hashedData = [NSData dataWithBytes:hashedChars length:32]; NSLog(@"hashedData = %@", hashedData); The log is showing like: hashedData = <abcdefgh abcdefgh abcdefgh abcdefgh abcdefgh abcdefgh abcdefgh abcdefgh> But what I need is to convert hashedData into NSString that looks like: NSString *someString = @"abcdefghabcdefghabcdefghabcdefghabcdefghabcdefghabcdefghabcdefgh"; So basically the string needs to be like hashedData except I don't want the angle brackets and spaces in between. Any help is much appreciated.

But it gets bad if you try to put breakpoint into the event. Why? I mean event is not run in the same thread that the windows hook is. That means that It shouldn't block HookCallback. It does however... I would really like to know why is this happening. My theory is that Visual Studio when breaking execution temporarily stops all threads and that means that HookCallback is blocked... Is there any book or valuable resource that would explain concepts behind all of this threading?

Hi all, could someone explain me what's the idea behind using Auto-Implemented Properties c#? public class Customer { public int ID { get; set; } public string Name { get; set; } } I get the motivation to use properties for private field, so we can determine how one can access a private field. But here - it's just like defining the field to be public from the first place. no? Is there a difference between defining a field to be "public const" or define it to have a get-only property ? Thanks Elad

BULK INSERT with inconsitant number of columns

- by aceinthehole

I am trying to load a large amount data in SQL server from a flat file using BULK INSERT. However, my file has varying number of column, for instance the first row contains 14 and the second contains 4. That is OK, I just want to make a table with the max number of columns and load the file into it with nulls for the missing columns. I can play with it from that point. But it seems that SQL Server when reaching the end of the line and having more columns to fill for that same row in the destination table, just moves on to the next line and attempts to put the data on that line to the wrong column of the table. Is there a way to get the behavior that I am looking for? Is there a table hint that I can use the specify this? Has anyone run into this before? Here is the code BULK INSERT #t FROM '<path to file>' WITH ( DATAFILETYPE = 'char', KEEPNULLS, FIELDTERMINATOR = '#' )

It's my code lyricsDownloader.cpp #include "lyricsDownloader.h" #include <curl/curl.h> #include <cstring> #include <iostream> #define DEBUG 1 ///////////////////////////////////////////////////////////////////////////// size_t lyricsDownloader::write_data_to_var(char *ptr, size_t size, size_t nmemb, void *userdata) // this function is a static member function { ostringstream * stream = (ostringstream*) userdata; size_t count = size * nmemb; stream->write(ptr, count); return count; } string AZLyricsDownloader::toProviderCode() const { /*this creates an url*/ } CURLcode AZLyricsDownloader::download() { CURL * handle; CURLcode err; ostringstream buff; handle = curl_easy_init(); if (! handle) return static_cast<CURLcode>(-1); // set verbose if debug on curl_easy_setopt( handle, CURLOPT_VERBOSE, DEBUG ); curl_easy_setopt( handle, CURLOPT_URL, toProviderCode().c_str() ); // set the download url to the generated one curl_easy_setopt(handle, CURLOPT_WRITEDATA, &buff); curl_easy_setopt(handle, CURLOPT_WRITEFUNCTION, &AZLyricsDownloader::write_data_to_var); err = curl_easy_perform(handle); // The segfault should be somewhere here - after calling the function but before it ends cerr << "cleanup\n"; curl_easy_cleanup(handle); // copy the contents to text variable lyrics = buff.str(); return err; } main.cpp #include <QString> #include <QTextEdit> #include <iostream> #include "lyricsDownloader.h" int main(int argc, char *argv[]) { AZLyricsDownloader dl(argv[1], argv[2]); dl.perform(); QTextEdit qtexted(QString::fromStdString(dl.lyrics)); cout << qPrintable(qtexted.toPlainText()); return 0; } When running ./maelyrica Anthrax Madhouse I'm getting this logged from curl * About to connect() to azlyrics.com port 80 (#0) * Trying 174.142.163.250... * connected * Connected to azlyrics.com (174.142.163.250) port 80 (#0) > GET /lyrics/anthrax/madhouse.html HTTP/1.1 Host: azlyrics.com Accept: */* < HTTP/1.1 301 Moved Permanently < Server: nginx/1.0.12 < Date: Thu, 05 Jul 2012 16:59:21 GMT < Content-Type: text/html < Content-Length: 185 < Connection: keep-alive < Location: http://www.azlyrics.com/lyrics/anthrax/madhouse.html < Segmentation fault Strangely, the file is there.

drupal bootstrap script: how to get list of all nodes of type x?

- by groovehunter

hi. I create a custom import and export, at the moment as an external script (via bootstrap), i plan to create a module in a more generic fashion lateron. I am building a frontend for nagios and for our host management and nagios configuration btw. Maybe it might become useful for other environments (networkmanagement) Now i need to know how to get list of all nodes of type x? I want to avoid direct SQL. A suggestion i got was to make an rss and parse it but i acess the drupal db a dozen times to extract various nodes, so it feels strange to do a web request for one thing So what i am looking for as newbie drupal dev is just a pointer to basic search module api for this task TIA florian

Gruber URL Regex tweak to capture "domain.com"

- by mootymoots

I found an updated version of John Gruber's regex for url matching in this post by user GianPac, which states it's been adapted to recognize url without protocol or the www part: (?i)\b((?:[a-z][\w-]+:(?:/{1,3}|[a-z0-9%])|www\d{0,3}[.]|[a-z0-9.-]+[.][a-z]{2,4}/?)(?:[^\s()<]+|(([^\s()<]+|(([^\s()<]+)))))(?:(([^\s()<]+|(([^\s()<]+))))|[^\s`!()[]{};:'\".,<?«»“”‘’])) Whilst this works in most cases, I found it does not match "google.com". It does match "google.comm" and "google.co.uk", so this must be a small oversight. The trouble is, I literally hate regex. It's the bane of my life. I just want to try and tweak this one more time to allow for "google.com" - can anyone throw me a pointer? I (think) it's something to do with this part of the code: +[.][a-z]{2,4}/?) ?
