• Versioning code in two separate projects concurently with subverison

  - by Matt1776

  I have a need to create a library of Object Oriented PHP code that will see much reuse and aspires to be highly flexible and modular. Because of its independent nature I would like it to exist as its own SVN project. I would like to be able to create a new web project, save it in SVN as its own separate project, and include within it the library project code as well. During this process, while coding the web application code and making commits, I may need to add a class to the library. I would like to be able to do so and commit those changes back to the libraries project code. In light of all this I could manage the code in two ways Commit the changes to the library back to a branch of its original base project code and make the branch name relevant to the web project I was using it with Commit the changes to the library back to the original code, growing it in size regardless of any specific references that might exist. I have two questions How can I include this library project code into a new project yet not break the subversion functionality, i.e. allowing me to make changes to each project individually? How I can keep the code synchronized? If I choose the first method of managing the library code I may want to grab changes from another branch and pull it in for use in another.

• BASIC Menu-driven program repeates twice after successful completion of first task.

  - by Zazu

  Hello, Im using Plato3 to write C programs. Im creating a menu-driven program but want to test out the basic concept of getting it to work #include<stdio.h> #include<ctype.h> int function1(); main(){ char s; do{ puts("\n choose the following"); puts("(P)rint\n"); puts("(Q)uit\n"); scanf("%c",&s); s=toupper(s); switch (s){ case 'P' : function1(); break; case 'Q' : return -1; break; } }while (function1()==0); } int function1(){ printf("Hello World"); return 0; } The problem is that once function1() returns the value 0, the whole program is echoed ... why ? Example : Running the program gives this : Hello WorldHellow World choose the following (P)rint (Q)uit Hello World choose the following (P)rint (Q)uit -- Any idea why ? Please help, thanks !!!!

• xmldocument and nested schemas

  - by Stuart

  Using c# and .net 3.5 I'm trying to validate an xml document against a schema that has includes. The schemas and there includes are as below Schema1.xsd - include another.xsd another.xsd - include base.xsd When i try to add the Schema1.xsd to the XmlDocument i get the following error. Type 'YesNoType' is not declared or is not a simple type. I believe i'm getting this error because the base.xsd file is not being included when i load the Schema1.xsd schema. I'm trying to use the XmlSchemaSet class and I'm setting the XmlResolver uri to the location of the schemas. NOTE : All schemas live under the same directory E:\Dev\Main\XmlSchemas Here is the code string schemaPath = "E:\\Dev\\Main\\XmlSchemas"; XmlDocument xmlDocSchema = new XmlDocument(); XmlSchemaSet s = new XmlSchemaSet(); XmlUrlResolver resolver = new XmlUrlResolver(); Uri baseUri = new Uri(schemaPath); resolver.ResolveUri(null, schemaPath); s.XmlResolver = resolver; s.Add(null, XmlReader.Create(new System.IO.StreamReader(schemaPath + "\\Schema1.xsd"), new XmlReaderSettings { ValidationType = ValidationType.Schema, XmlResolver = resolver }, new Uri(schemaPath).ToString())); xmlDocSchema.Schemas.Add(s); ValidationEventHandler valEventHandler = new ValidationEventHandler (ValidateNinoDobEvent); try { xmlDocSchema.LoadXml(xml); xmlDocSchema.Validate(valEventHandler); } catch (XmlSchemaValidationException xmlValidationError) { // need to interogate the Validation Exception, for possible further // processing. string message = xmlValidationError.Message; return false; } Can anyone point me in the right direction regarding validating an xmldocument against a schema with nested includes.

• What's an effective way to move data from one open browser tab to another?

  - by slk

  I am looking for a quick way to grab some data off of one Web page and throw it into another. I don't have access to the query string in the URL of the second page, so passing the data that way is not an option. Right now, I am using a Greasemonkey user script in tandem with a JS bookmarklet trigger: javascript:doIt(); // ==UserScript== // @include public_site // @include internal_site // ==/UserScript== if (document.location.host.match(internal_site)) { var datum1 = GM_getValue("d1"); var datum2 = GM_getValue("d2"); } unsafeWindow.doIt = function() { if(document.location.host.match(public_site)) { var d1 = innerHTML of page element 1; var d2 = innerHTML of page element 2; //Next two lines use setTimeout to bypass GM_setValue restriction window.setTimeout(function() {GM_setValue("d1", d1);}, 0); window.setTimeout(function() {GM_setValue("d2", d2);}, 0); } else if(document.location.host.match(internal_site)) { document.getElementById("field1").value = datum1; document.getElementById("field2").value = datum2; } } While I am open to another method, I would prefer to stay with this basic model if possible, as this is just a small fraction of the code in doIt() which is used on several other pages, mostly to automate date-based form fills; people really like their "magic button." The above code works, but there's an interruption to the workflow: In order for the user to know which page on the public site to grab data from, the internal page has to be opened first. Then, once the GM cookie is set from the public page, the internal page has to be reloaded to get the proper information into the internal page variables. I'm wondering if there's any way to GM_getValue() at bookmarklet-clicktime to prevent the need for a refresh. Thanks!

• Recursive templates: compilation error under g++

  - by Johannes

  Hi, I am trying to use templates recursively to define (at compile-time) a d-tuple of doubles. The code below compiles fine with Visual Studio 2010, but g++ fails and complains that it "cannot call constructor 'point<1::point' directly". Could anyone please shed some light on what is going on here? Many thanks, Jo #include <iostream> #include <utility> using namespace std; template <const int N> class point { private: pair<double, point<N-1> > coordPointPair; public: point() { coordPointPair.first = 0; coordPointPair.second.point<N-1>::point(); } }; template<> class point<1> { private: double coord; public: point() { coord= 0; } }; int main() { point<5> myPoint; return 0; }

• Is there a Scala version of .irbrc or another way to define some default libraries for REPL use?

  - by Tom Morris

  I've written a little library that uses implicits to add functionality that one only needs when using the REPL in Scala. Ruby has libraries like this - for things like pretty printing, firing up text editors (like the interactive_editor gem which invokes Vim from irb - see this post), debuggers and the like. The library I am trying to write adds some methods to java.lang.Class and java.lang.reflect classes using the 'pimp my library' implicit conversion process to help you go and find documentation (initially, with Google, then later possibly with a JavaDoc/ScalaDoc viewer, and maybe the StackOverflow API eventually!). It's an itch-scratching library: I spend so much time copying and pasting classnames into Google that I figured I may as well automate the process. It is the sort of functionality that developers will want to add to their system for use only in the REPL - they shouldn't really be adding it to projects (partly because it may not be something that their fellow developers want, but also because if you are doing some exploratory development, it may be with just a Scala REPL that's not being invoked by an IDE or build tool). In my case, I want to include a few classes and set up some implicits - include a .jar on the CLASSPATH and import it, basically. In Ruby, this is the sort of thing that you'd add to your .irbrc file. Other REPLs have similar ways of setting options and importing libraries. Is there a similar file or way of doing this for the Scala REPL?

• Core jQuery event modification problem

  - by DSKVR

  I am attempting to overwrite a core jQuery event, in this case the keydown event. My intention is to preventDefault() functionality of Left(37), Up(38), Right(39) and Down(40) to maintain the consistency of hot keys in my web application. I am using the solution provided here for the conditional charCode preventDefault problem. For some reason, my function overwrite is simply not firing, and I cannot put my finger on the problem. I am afraid that over the past 30 minutes this issue has resulted in some hair loss. Anybody have the remedy? /* Modify Keydown Event to prevent default PageDown and PageUp functionality */ (function(){ var charCodes = new Array(37,38,39,40); var original = jQuery.fn.keydown; jQuery.fn.keydown = function(e){ var key=e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0; alert('now why is my keydown mod not firing?'); if($.inArray(key,charCodes)) { alert('is one of them, do not scroll page'); e.preventDefault(); return false; } original.apply( this, arguments ); } })();

• How to treat Base* pointer as Derived<T>* pointer?

  - by dehmann

  I would like to store pointers to a Base class in a vector, but then use them as function arguments where they act as a specific class, see here: #include <iostream> #include <vector> class Base {}; template<class T> class Derived : public Base {}; void Foo(Derived<int>* d) { std::cerr << "Processing int" << std::endl; } void Foo(Derived<double>* d) { std::cerr << "Processing double" << std::endl; } int main() { std::vector<Base*> vec; vec.push_back(new Derived<int>()); vec.push_back(new Derived<double>()); Foo(vec[0]); Foo(vec[1]); delete vec[0]; delete vec[1]; return 0; } This doesn't compile: error: call of overloaded 'Foo(Base*&)' is ambiguous Is it possible to make it work? I need to process the elements of the vector differently, according to their int, double, etc. types.

• Problem with "moveable-only types" in VC++ 2010

  - by Luc Touraille

  I recently installed Visual Studio 2010 Professional RC to try it out and test the few C++0x features that are implemented in VC++ 2010. I instantiated a std::vector of std::unique_ptr, without any problems. However, when I try to populate it by passing temporaries to push_back, the compiler complains that the copy constructor of unique_ptr is private. I tried inserting an lvalue by moving it, and it works just fine. #include <utility> #include <vector> int main() { typedef std::unique_ptr<int> int_ptr; int_ptr pi(new int(1)); std::vector<int_ptr> vec; vec.push_back(std::move(pi)); // OK vec.push_back(int_ptr(new int(2)); // compiler error } As it turns out, the problem is neither unique_ptr nor vector::push_back but the way VC++ resolves overloads when dealing with rvalues, as demonstrated by the following code: struct MoveOnly { MoveOnly() {} MoveOnly(MoveOnly && other) {} private: MoveOnly(const MoveOnly & other); }; void acceptRValue(MoveOnly && mo) {} int main() { acceptRValue(MoveOnly()); // Compiler error } The compiler complains that the copy constructor is not accessible. If I make it public, the program compiles (even though the copy constructor is not defined). Did I misunderstand something about rvalue references, or is it a (possibly known) bug in VC++ 2010 implementation of this feature?

• Decimal To Octal Converter, last digit issue

  - by Srishan Supertramp

  I tried making a C program to convert a user entered decimal number to octal. I wrote the C code with my own logic without any research of how other users try to do it. It works fine for the number 601 and some other numbers but for most numbers it returns the octal equivalent with the last digit being 1 less than it should be. For 75 it returns 112 instead of 113. I realize using printf with %o gets the job done but it's kind of defeating the purpose of learning to program. Here's my code: #include <stdio.h> #include <math.h> /* converting decimal to octal */ int main() { int n,x,y,p,s; printf("Enter a decimal number "); scanf("%d",&x); s=0;p=0; while (x!=0) { y=x%8; s=s+y*pow(10,p); x=(x-y)/8; p=p+1; } printf("the octal equivalent is: %d\n",s); getch(); return 0; }

• I want tell the VC++ Compiler to compile all code. Can it be done?

  - by KGB

  I am using VS2005 VC++ for unmanaged C++. I have VSTS and am trying to use the code coverage tool to accomplish two things with regards to unit tests: See how much of my referenced code under test is getting executed See how many methods of my code under test (if any) are not unit tested at all Setting up the VSTS code coverage tool (see the link text) and accomplishing task #1 was straightforward. However #2 has been a surprising challenge for me. Here is my test code. class CodeCoverageTarget { public: std::string ThisMethodRuns() { return "Running"; } std::string ThisMethodDoesNotRun() { return "Not Running"; } }; #include <iostream> #include "CodeCoverageTarget.h" using namespace std; int main() { CodeCoverageTarget cct; cout<<cct.ThisMethodRuns()<<endl; } When both methods are defined within the class as above the compiler automatically eliminates the ThisMethodDoesNotRun() from the obj file. If I move it's definition outside the class then it is included in the obj file and the code coverage tool shows it has not been exercised at all. Under most circumstances I want the compiler to do this elimination for me but for the code coverage tool it defeats a significant portion of the value (e.g. finding untested methods). I have tried a number of things to tell the compiler to stop being smart for me and compile everything but I am stumped. It would be nice if the code coverage tool compensated for this (I suppose by scanning the source and matching it up with the linker output) but I didn't find anything to suggest it has a special mode to be turned on. Am I totally missing something simple here or is this not possible with the VC++ compiler + VSTS code coverage tool? Thanks in advance, KGB

• Ideas Needed for a Base Code System

  - by Tegan Snyder

  I've developed a PHP web application that is currently in need of a strategic restructuring. Currently when we setup new clients we give them the entire code base on a subdomain of our main domain and create a new table for them in the database. This results in each client having the entire codebase, meaning when we make bug changes, fixes we have to go back and apply them independently across all clients and this is a pain. What I'd like to create is a base code server that holds all the core PHP files. base.domain.com Then all of our clients (client.domain.com) will only need a few files: config.php would have the database connection information. index.php - displays the login box if session non-existant, otherwise it loads baseline code via remote includes to base.domain.com. My question is does my logic seem feasible? How do other people handle similar situations by having a base code? Also.... Is it even possbile to remotely include PHP files from base.domain.com and include them in client.domain.com? Thanks, Tegan

• Simple average calculation

  - by sasquatch90

  I'm trying to write program calculating average of given numbers stored in an array. Amount of numbers should be not more than 100, and user should input them until a !int variable is given : #include <iostream> #include <conio.h> using namespace std; double average(int tab[], int i){ int sum=0; for(int j=0; j<i; ++j){ sum+=tab[j]; } return (double)sum/i; } int main() { int tab[100]; int n=0; int number=0; do { if(n < 100){ cout << "Give " << n+1 << " number : "; cin >> number; tab[n]=number; number=0; ++n; } else{ break; } } while( !isdigit(number) ); cout << average(tab, n) << endl; getch(); return 0; } Why after giving char, it prints me 'Give n number:' for all empty cells of my array ? It should end and use only given numbers.

• LNK2019 Against CArray Add, GetAt, GetSize, all includes are present

  - by David J

  I'm having some issues trying to Compile a DLL, but I just can't see where this linking error is coming from. My LNK2019 is: Exports.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: int __thiscall CArray<struct HWND__ *,struct HWND__ *>::Add(struct HWND__ *)" (__imp_?Add@? $CArray@PAUHWND__@@PAU1@@@QAEHPAUHWND__@@@Z) referenced in function "int __stdcall _Disable(struct HWND__ *,long)" (?_Disable@@YGHPAUHWND__@@J@Z) Disable(...) is... static BOOL CALLBACK _Disable(HWND hwnd, LPARAM lParam) { CArray<HWND, HWND>* pArr = (CHWndArray*)lParam; if(::IsWindowEnabled(hwnd) && ::IsWindowVisible(hwnd)) { pArr->Add(hwnd); ::Enable(hwnd, FALSE); } } This is the first function in Exports.cpp; right above it is #include <afxtempl.h> I have the Windows 7.1 SDK installed (and have tried reinstalling both that and VS2010). The exact same project compiles perfectly fine on other machines, so it can't be the code itself.. I've spent countless errors researching, which led to desperate attempts of just changing random values in the solution file, including different Windows headers, etc. My last resort is getting to be just reinstalling the OS completely (assuming it's actually a problem with the Windows SDK being incorrect or something). Any suggestions at all would be a huge help. EDIT: I've added /showIncludes on the cpp giving issues, and I do see afxtempl.h being included. It's being included multiple times due to other headers including it, but it is there (and it is from the same directory every time): 1> Note: including file: C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\atlmfc\include\afxtempl.h

• C++ Constructor With Parameters Won't Initialize, Errors C2059 and C2228

  - by Some Girl

  I'm a C# programmer trying to muddle through C++ to create a Windows Forms Application. I have a Windows Form that makes use of a user-created class. Basically I'm trying to use a constructor that takes parameters, but my form won't let me initialize the object with parameter. Here's the code, hopefully somebody can explain the problem to me because I'm completely baffled... Here's my header file: BankAcct.h public ref class BankAcct { private: int money; public: BankAcct(); BankAcct(int); void Deposit(int); void GetBalance(int&); }; And my definition file: BankAcct.cpp #include "StdAfx.h" #include "BankAcct.h" BankAcct::BankAcct() { money = 0; } BankAcct::BankAcct(int startAmt) { money = startAmt; } void BankAcct::Deposit(int depAmt) { money += depAmt; } void BankAcct::GetBalance(int& balance) { balance = money; } And finally my main form. Won't copy the whole thing, of course, but I'm trying to declare the new bank account object, and start it with a balance of say $50. private: BankAcct myAccount(50); //does not work! WHY?? //private: //BankAcct myAccount; //works then in the form constructor my code is this: public: frmBank(void) { InitializeComponent(); int bal; myAccount.GetBalance(bal); lblBankBalance->Text += Convert::ToString(bal); } I've included the BankAcct.h file at the top of my frmBank.h, what else am I doing wrong here? It works great if I use the default constructor (the one that starts the bank balance at zero). I get the following error messages: error C2059: syntax error: 'constant' and error C2228: left of '.GetBalance' must have class/struct/union Thank you for any and all help on this one!!

• How can I get swig to wrap a linked list-type structure?

  - by bk

  Here's what I take to be a pretty standard header for a list. Because the struct points to itself, we need this two-part declaration. Call it listicle.h: typedef struct _listicle listicle; struct _listicle{ int i; listicle *next; }; I'm trying to get swig to wrap this, so that the Python user can make use of the listicle struct. Here's what I have in listicle.i right now: %module listicle %{ #include "listicle.h" %} %include listicle.h %rename(listicle) _listicle; %extend listicle { listicle() {return malloc (sizeof(listicle));} } As you can tell by my being here asking, it doesn't work. All the various combinations I've tried each fail in their own special way. [This one: %extend defined for an undeclared class listicle. Change it to %extend _listicle (and fix the constructor) and loading in Python gives type object '_listicle' has no attribute '_listicle_swigregister'. And so on.] Suggestions?
