C/C++ :: Implementing Parallel Gaussian Elimination Using Message Passing
Nov 6, 2014I'm implementing parallel gaussian elimination using message passing. However, there is a problem with allocations and I don't get the correct answer. The matrix A is decomposed into smaller matrices (ie subA) and used into a buffer.
int n = 2; // for matrix size 1024 (additionally 2048 and 4096 was calculated)
#define MAXN 2
volatile float **a, *b, x[MAXN];
// generate a and b randomly; x is set to 0
void generateMatrix() {

C# :: Using Timer To Refresh Interface - Keep Getting Error Message
Feb 3, 2015I've been using a timer to refresh the listview on my application, but after half a second, I get the error message at first try/catch method in RefreshPlot() in PlotComponent.cs:
Quote An exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in Marketplace.exe but was not handled in user code
Additional information: There is already an open DataReader associated with this Connection which must be closed first.
Visual C++ :: Implementing Real Time Graph To Application?
Nov 15, 2013I was assigned a project to implement a real time graph to an application which continuously outputs data numerically through the GUI. The application that was created to do this is written in C.
I have to turn those numerical numbers into a graphical display that is periodically updated to appear as real time.
My adviser suggested using NTgraph [URL] ...... I had no clue how to implement this to my code and was finally able to understand that the .OCX needs to be registered as a COM and then imported to the application using visual studios. However, I get an error when I try importing it since it is in C (Visual Studios 8) and not an MFC application.
So my question is if it would be possible to implement the ActiveX control to my application even though it is not an MFC application and how to go about it.
C++ :: Write Interactive Text Based Menu Interface (using A Loop)
Sep 27, 2013Write an interactive text based menu interface (using a loop) that will allow the user to
Enter a task or assignment Display all of the tasks that are in the file Find a task by Course Quit For each task, you need to keep track of:
Course Name that it is for (e.g., CS162)
Description of the assignment (e.g., Finish Lab 2)
Due date (e.g., 9/26/2009)
Allow the program to keep looping until user wants to quit. When the program starts, it should load the tasks from external file ("tasks.txt") into memory. When user enters the three items of a task, the program needs to read them in, save them in memory and eventually write them to the external data file ("tasks.txt"). The file format could look like: (The ';' is used as a delimiter or field seperator.)
Some Implementation Requirements:
Write at least four functions WITH arguments for this assignment. Use struct named Task to model task Use array of structs to model the collection of tasks. Hint: In this assignment, the description and course name may have multiple words in it. Therefore, you now SHOULD read using the 3 argument version of get. Watch out. When using the 3 argument version of get you need to make sure to remove the delimiter or newline. Therefore, anytime you read (even a confirmation message), make sure to eat the newline! Make sure to have a delimiter written between each item in the file – like a newline. This will be important when you read the information back from the file.
This is my code so far:
#include <iostream>
int main()
{
char cname[25],desc[20];

Visual C++ :: Passing Message Using Active Directory?
Jan 29, 2015I have a DLL developed using pure VC++ (all unmanaged code that doesn't use .NET framework). This DLL will be deployed in different client PCs within a network and will act like an agent.
Now I have establish a communication between this DLL and a WCF web service, that will be deployed in a server PC. The Service will first get a list of PCs either name or IP Address within a network using LDAP (Active Directory) and once, we get the PCs, I have to establish a communication between the web service and the agents that reside in these client PCs,
How can I accomplish this?
Visual C++ :: Debugging Access Write From Error Message

C :: Program Finding Max Of Graph
Oct 29, 2013this is my first year programming, and in my class, each week we have to write a program. last week we wrote a program in c that made random value point and made a graph of the random points that continued on forever. this week, we have to use statistical functions to find the sum, mean, max, and min of the graph. below is the code i have so far.
Code:
#include <stdlib.h>
#include <strings.h>
#include <stdio.h>
#include <stdbool.h>
#include "SwinGame.h"
[code]....
so, as you can see from the code, the parts i need are finding/ coming up with a function to find the max min sum and mean of the functions.

C++ :: GLSL Heightmap Coloring (OpenGL)
Aug 27, 2013I recently made a heightmap, it uses a triangle strip /row, and I try to figure out how can i color the triangles one by one. So, for example I have a color array of 9:
[0.0f,0.2f,0.6f //a triangles first vertex
0.0f,0.4f,0.3f //second vertex
0.0f,0.7f,0.2f] //third vertex
And I want to use it to color all triangles with it. My heightmap coords are in a vector:
vector<GLfloat> hmapcrds [x1,h1,z1; x2,h2,z2;...]
Like this:
c1 c2 c3 c4 c5 //row 1
c6 c7 c8 c9 c10 //row 2 coordinates
index array:c6->c1->c7->c2 ...cn->c(n-rwosize)->c(n+1)->cn->c(n-rwosize+1)
I draw my elements with a VAO and drawelements/row; (i tried drawrange but didnt work)
...
glGenVertexArrays(1,&VertArrObj);
glBindBuffer(GL_ELEMENT_ARRAY_BUFFER,indexBuffer);
glBufferData(GL_ELEMENT_ARRAY_BUFFER,sizeof(GLuint)*v_heightIndexes.sie(),&v_heightIndexes[0],GL_STATIC_DRAW);
glBindBuffer(GL_ARRAY_BUFFER,vertexBuffer);
[Code] ....
I think it want to index my color array too, so how can i do that it only reads the 3 colors from my array, the repeat it /vertex/triangle till the end of drawing.
The shaders work fine, i changed the map to a triangle so it applied these colors, but with the map "I see only darkness before me".
with my working shader without color "in" - height coloring: [URL] ....
(I also want to do texturing per triangle.)
C++ :: Parabolic Shot Program - Calculate And Graph Time Vs Distance
Nov 13, 2013It is supposed to calculate and graph time vs. distance. The problem I have is graphing, if I put too small values for Vi, which is the initial velocity, it just graphs one or two points, because t is too small. I already tried to adjust t with 'if(t<10) t=t*10; if (t>100) t=t/10;', But it seems not to solve my problem.
Other truble I have is that, as the graph is parabola, core values are very close together, and when plotted, these values are in the same line on the screen.
Here is my code:
#include<stdio.h>
#include<conio.h>
#include<math.h>
void main() {
float x, y, hmax, t, amax, vi, v, a, b, g, ang; /*x= x coordinate, y= y coordinate, hmax= maximum height,

C/C++ :: Implementing Program That Sends And Receives Raw Ethernet Frames
Apr 15, 2013I am fairly new to the topic of the ethernet and the data link layer and I am trying to write a C program which allows the sending and receiving of ethernet frames.
I am trying to have my program send the ethernet frame to myself, so the program will have the same source and destination mac addresses.
The program that I'm using is a modified version of the code from [URL] ....
I keep having trouble with the recvfrom() function, it seems to just be blocking and the program doesn't terminate. From the code, I am trying send the ethernet frame and have the recvfrom() function be able to retrieve the frame and store it in a buffer. But because recvfrom() function is just blocking, it seems to me that the sendto() function was not able to successfully send the frame.
Here is my code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/socket.h> /* Must precede if*.h */
#include <linux/if.h>
#include <linux/if_ether.h>
[Code] ....
This is on a linux machine ....
C :: Program Terminates Without Message
Jan 15, 2014I'm trying to parallelize bottom's up merge sort algorithm. Firstly, i must have working procedural code.
I rember I had my code working last week but I made some changes ( probably to arguments passed to sort function ), i run my program several times without rebuilding it so i though it's still working.
Now i came back to my code and my program terminates without any message which confuses me. I debbuged merge function and it seems to work well, at the end i have sorted array.
fprintf doesn't print any value to my stdout.

View 4 Replies View RelatedC/C++ :: Writing A Program Which Includes Encoding And Decoding A Message?
Oct 31, 2014I am writing a porgram which includes encoding and decoding a message.Now I am doing the encoding part.
The goal is to encode a message using similar approach as Caesar Cipher. But instead of alphabets, I am going to use the entire ASCII code of total 128 codes to be the base.
And it is not a simple shifting, it is a rotation. This means if you want to shift 4 units from char <DEL>, it will come back to the first code in ASCII Code which is at dec 0 char <NUL> and starts the shifting again. It won't jump if the limit of ASCII Code is reached.
Here we've got 7 different malls' names and I am going to encode them with a shift n. I think n is free to set, so here I just set it as 5. This is also called the key.
I have written something and I think it should work, but after all it doesn't. And I don't get what is wrong.
Here is my program:
#include <iostream>
using namespace std;
const int NUMBER_OF_MALLS = 7;
const int MALL_NAME_LENGTH = 13;
const int NAME_SIZE = MALL_NAME_LENGTH + 1;
void encode(int key, char plain[], int length, char encoded[]) {
for (int i = 0; i < MALL_NAME_LENGTH; i++)
[code].....
Note that I am not going to use other libraries, just <iostream>.

Visual C++ :: Program To Auto Login Website - Waiting With Message Loop
Aug 25, 2013I am writing a program to auto login in a web site. Before making next attempt I have to wait for some time like some 10 seconds(it is configurable). But during waiting UI should not freeze. I wrote code something like this. Here event m_hEvent[1]) will be set by another thread after 10 seconds.The problem is UI still freezes some times!
while(1)
{
//m_hEvent[1] will be set by another thread after 10 seconds
dwRet = MsgWaitForMultipleObjects(1, &m_hEvent[1], FALSE, dwMilliseconds, QS_ALLINPUT);

C# :: Static In Interface
Jul 1, 2014I have the following scenario: I plan to have an xml configuration file.I have a trader that lunch few strategies, each have different configurations. I plan to have all configuration reside in the same file as different nodes.
Now I want that each strategy will hard code the name of node it will loop up for its parameters. Since those paramters are requered for the init and I use DI (configuration are passed in the constructor) I want to make it static.
So this would be something like.
public class Strategy: Base_strategy{
public const string _conf_name = "XXX";
public static string get_conf_name(){
[Code]....
Since other people will code strategies, I want each strategy to implement this static function. I wanted to do this in an interface so that anyone coding new strategy,implementing the base strategy will have to code this static function as part of the contract.
