C++ :: Kronecker (direct) Vector Product
Feb 19, 2013How to code the Kronecker/direct product of two vectors??
The direct product of the vectors a and b is given as the matrix below (note "x" refers to x with a circle around it and is the symbol for a Kronecker product):
(a1, a2,..., an) "x" (b1, b2,...,bn) = [a1b1, a1b2,..., a1bn]
[a2b1, a2b2,..., a2bn]
[ . . . . ]
[ . . . . ]
[ . . . . ]
[anb1, anb2,..., anbn]
The way I have coded the rest of the program is such that the matrix shown here is represented by a vector of length equivalent to the number of elements in the matrix. So I want the Kronecker product to give me a vector of length n^2 (where n is the number of elements in each initial vector).
C++ :: Shared Library Throws Exception But Not Caught
Jan 10, 2013A test program of mine loads a shared library (.so file). A function call in the shared library throws an exception that I am trying to catch in the main function of my test program. (I know that exception is being thrown for sure, I wrote the library to do that.)
However in the main program, the exception is not being caught. The flow of program goes past the catch block like no error has occurred. I am using g++ and I load the shared file using -l option. Only trying to load the program statically I got the following error:
/usr/bin/ld: cannot find -lmy-shared-library
collect2: ld returned 1 exit status
Why the exception is not getting caught.

C++ :: Smart Array Class - Constructor Throws Wrong Exception
Jan 24, 2014Writing a smart array class for my C++ class. I'm running into a problem where the constructor apparently throws the wrong exception. Compiled on G++ with C++11 extensions enabled.
Code:
// headers
#include <iostream>
#include <utility>
#include <cctype>
// stuff we need from namespace std
using std::cout;
using std::cin;
[Code] .....
When I try to check the error-handling code, when I enter a size less then two, Array's ctor throws InvalidSize, and gets caught, all good. But when I enter a letter, the ctor also seems to throw InvalidSize!

Visual C++ :: Prevent DLL From Being Loaded / Injected
Dec 12, 2012If you're writing a .dll you can prevent that dll from getting loaded into some processes by returning false from the dllmain.
I'm looking for a way to do it the other ay around. I have an exe, and I want to prevent a certain hook dll from getting loaded/injected into my exe.
A customer is running some software which loads a hook dll into our exe, and this is subsequently preventing our application from running as intended. Both our software as well as the third party app is required, and there is no way to get the third party dll changed. (no longer supported).
C++ :: User Input Loaded Into Array Of Elements
Mar 19, 2014I am compiling using Microsoft Visual C++ and I am trying to create a program that ask's the user for 10 numbers, and these numbers will have to be loaded into a one dimensional array of 10 elements. I read up online as well as my book and looked at sample programs, then created mine which was similar to the sample programs I looked at, but the sample ones compile , while I get C2059 and C2061 Syntax Errors. I am new to programming so I understand it could be one small thing but I after looking over it I am completely clueless.
Heres my program:

C :: Displaying A String Loaded From A Text File
Jan 19, 2014I'm working on a program that can load all words from a dictionary "English2.txt" (it's attached to the post), then put every word into a 2-dimensional matrix (every line is reserved for one word) and display them. After loading every word into a matrix, when I try to display first 8 words with printf, I can't do it without '' at the end of a line. Otherwise only the 8th word is displayed... What's more, when I try to read the length of the first word with strlen, it says, that it has 4 characters (in fact there are only 3 and it's the word "AAA"). What could be the reason for that?
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdint.h>
int main()
{
FILE *fp;
char buffer[32];
[Code]...
C++ :: Dynamically Loaded Library - DLL Call Sometimes Works
Apr 22, 2013I have a question about a dynamically loaded library I am using. I have called it SqlWrite, it is for connecting and writing to a Microsoft SQL server DB. I have a function in it that is defined as:
extern "C" {
__declspec(dllexport) RETCODE __cdecl SqlExecS(SQLHANDLESTR* h, LPCSTR Statement) {
RETCODE RetCode;
std::string input = Statement;
std::wostringstream conv;
conv << input.c_str();
std::wstring wCmd(conv.str());
[Code] ....
I then load it in another MSVC project as:
#ifdef WIN32//C:UsersaDocumentsVisual Studio 2012ProjectsGetPageSourceDebugGetPageSource.dll
#pragma message("WIN32 is defined")
#ifdef _DEBUG
SetErrorMode(0);
[Code] ....
As you can see, inside the prototyped function "SqlExecSP", I cout (or, rather, wcout for wide characters) the sql statement i am running, and the return code of the sql statement. a sql return code of "0" is equivalent to "SQL_SUCCESS". Then, I cout " got player again " after executon of SqlExecSP alias SqlExecS.
This usually works, and gives me following sample output:
exec SELECT [PlayerID], [FirstName], [LastName], [TeamID] FROM [soccer].[dbo].[Players] WHERE LastName = 'Abdellaoue' AND FirstName = 'Mohammed' retcode 0
RETURNING FROM EXECSP NOW!!!
got player again
However, sometimes, the program crashes somewhere between outputting "RETURNING FROM EXECSP NOW!!!" and outputting " got player again ", i.e. the output is then:
exec SELECT [PlayerID], [FirstName], [LastName], [TeamID] FROM [soccer].[dbo].[Players] WHERE LastName = 'Abdellaoue' AND FirstName = 'Mohammed' retcode 0
RETURNING FROM EXECSP NOW!!!
As you can see, it doesn't output the next line " got player again ", because it somehow crashes in between.
However,t he only line that should be executed between this, as far as I can understand, is the actual return of the DLL function SqlExecS, prototyped as SqlExecSP in my calling code, i.e. the only line that should be executed in between is:
return RetCode;
However, somehow, this fails, even though RetCode is "0", as I can see at the end of the output
exec SELECT [PlayerID], [FirstName], [LastName], [TeamID] FROM [soccer].[dbo].[Players] WHERE LastName = 'Abdellaoue' AND FirstName = 'Mohammed' retcode 0
Now, why sometimes this crashes, and sometimes this works. I.e, I can sometimes call this function x times, and it doesnt fail, outputting " got player again " right after the calls, and sometimes, it fails somewhere in between, at call x, y, or z, i.e. sometimes i can execute it ten times successfully and sometimes i can't, even though the return code is still 0, and it just fails somewhere in between. I am not sure if it has to do with the call being a call to a dynamically loaded DLL function, but I can't see where else the error is.
Why this can be failing, and at different, seemingly random times?

View 2 Replies View RelatedC++ :: Calling Dynamically Loaded Function From DLL Destruction Error?
Apr 18, 2013I have two projects (Projects A and B). Project A is a dll project, defining a function called "regex".
Project B dynamically loads this DLL, and calls Project A's "regex" function via LoadLibrary/GetProcAddress.
Regex takes a pointer to an std::vector (std::vector<std::cmatch>).
When debugging ProjectB, I can see that, within the code from ProjectA (in the "regex" call), a loop that loops through the elements of the vector outputs all the elements in the vector to console as expected. But the loop in ProjectB ( which executes after ProjectA), which also loops through the vector, and, is supposed to output the elements of the vector, outputs empty strings, not, as I would expect, the same strings (which contain results), as in the loop in Project A.
How is this happening. Does this have anything to do with it being a DLL, and, maybe, somehow values/memory addresses (or something similar) of the vector/its elements being destructed across the Projects/Dlls?
Output and Code See Below:
Output Loop in A:
Un
Un
Output Loop in B: (empty) (i.e. none)
Project A DLL Header (interface.h):
#include "stdafx.h"
#include <vector>
#include <regex>
extern "C" {__declspec(dllexport) int __cdecl regex(std::string target,std::string rgx, std::vector<std::cmatch*>* matches);}

C++ :: Game Editor - How To Make A Rectangle Selection Tool
Dec 20, 2014I'm working with a game editor program, where the player can create their own maps. Right know I'm working with collisions, and since it's unpredictable where the player place the objects like trees, houses and cars...etc have I an idea with making a rectangle selection tool. Where the player can drag a collision box around the object, so the sprite stops when it hits the box. The problem is that I dont know how to make a tool like that. so my question is how do I create a tool like that (see picture under for more information)?
btw I'm using the SDL framework
