Visual C++ :: Create A Program That Perform Same Calculation For Every Oscillation
Jan 17, 2014
I am reading from a text file and want to create a program that will perform the same calculation for every oscillation.
The text file I'm reading from is attached to this post. A3.txt
The program that I've written is as follows:
Code:
#include <iostream>
#include <fstream>
using namespace std;
int main() {
ifstream inFile ("AP1.txt");
ofstream results_file ("APDuration.txt");
[Code]...
Where I'm having trouble is in having the inFile.seekg function iterate to the next series of values.
Here is what the data file looks like in a graph:
In a nutshell, my program will read the duration of each action potential from a point called "dVmax" (where the upstroke is at its maximum upward rate of change) to the point of 90% repolarization (on the downstroke where 90% of the total wave amplitude is subtracted from the volts at peak amplitude).
If you would like to test my program on one action potential, here is one action potential : AP1.txt
I am really unsure how to keep within the boundries and still perform the function I need. My code functions normal when I have both categories 'buy' and 'sell' in the queue which is my main goal and I should be clocked out on this function BUT, If the queue is missing all 'sell' data, it segment faults.
I don't want to change any of the functionality, just get rid of the segment fault error. It appears b < buydat.size() and buydat[b+1] are in conflict. The purpose of the algorithm is capture the record sets in groups of 7 from data coming in from the www as strings. In that group/set, I pattern match for the string 'Buy' and if true, insert record into vector for processing. I also need the price (y = 3)
How do I capture buydat[2] and buydat[3] in groups of 7 without a segment fault?
is it better to reuse an existing variable or create a new variable for the following situation:
/* Is this faster: */ glm::mat4 newViewModelMatrix = (*existingViewMatrix) * (*existingModelMatrix); /* Or is this faster? */ glm::mat4 existingViewModelMatrix; /* declared in class header - initial value assigned in class constructor */ existingViewModelMatrix = (*existingViewMatrix) * (*existingModelMatrix);
My assignment is : Please use C type strings ( array representation of strings). Write a program that will ask the user to enter a string. It will then regard that string as a worked-on string and allow the user to perform the following editing functions on it:
s – search i – insert a – append d – delete a – append d – delete r – replace e – exit s – search
This option will allow the user to search for a specified string in the worked-on string. If the string is
found, it will display the starting index (position) of the searched string in the worked-on string.
here is what i have so far.
#include <iostream> #include <cstring> using namespace std; int main() { char a_string[80];
I am basically trying to make a program for a calculator. I am struggling with how to do the sine calculation. this calculation will take place at line 158.
#include <iostream> #include <cmath> using namespace std; int main() {
I'm working on a payroll program and I'm having problems that are causing calculation errors.
My input file is 1234FredJones4025.00 2345 TerrySmith6010.00
The errors I get are from the regular pay, over time pay, gross pay, tax amount and net pay calculations. They all look similar to this (6e+002). I believe they are occurring because regular pay isn't calculating correctly and the rest depend on that for their calculations. However, I can't see why regular pay isn't calculating correctly.
#include <fstream> #include <iostream> #include <iomanip> using namespace std; class payroll{ ifstream fin; char employeeid[100];

I want to set a value to a specific element in a web site. Perform a click on an element that is image. Get the result <span> text into string variable...
trying to understand operator overloading, and i wrote some code just to define a "-" operator to do a simple subtraction. SO, i wrote a program that can perform a subtraction between two objects and put the result in the third object. now I Just cant show the result on the console. And also can anyone define the meaning of [b1.x], like I want to know am I assigning the value to the "b1"object or the x variable? This is a very concept that I need to understand.
#include<iostream> using namespace std; struct Ok { int x; int y; };
Ok operator-(const Ok& a , const Ok& b)
{ Ok result; result = (a - b); return result; } int main()

I am having some column say "Response" column in my Datatable.Now I want to fetch this particular column value and compare this value with the maximum response how to fetch and compare it in C#.net .. This is my code.
for (int i = 0; i < DataFilter.Rows.Count; i++) { DataRow dr = DataFilter.Rows[i]; DataView dv2 = new DataView(); dv2 = DataFilter.DefaultView;
how to use template parameters to perform arithmetic operations on objects.
I feel that it would best to demonstrate my issue rather than try and explain it.
Sample:
// Fundamental object structure template<int T> struct myInt { myInt() { value = T; };
[Code]....
What I don't know is how to get a hold of the T variable to add them through the 'add' structure. Also, might any of this have to do with sequence wrappers?
seq_c<T,c1,c2,... cn> is essentially what I'm thinking of. Where T in this case is the type and c to the nth c are the values.
Following is the code for inserting elements in a tree and then retrieving them back using inorder traversal technique elements are getting inserted just fine,but the code doesn't displays the elements of the tree while performing inorder traversal..
I am trying to create a OCX from a C++ dll., Here's the scenario I have a C++ dll and this dll needs to be called in VB.net program my boss want's me to create an OCX out of this.
C++ dll and use it in a VB.net class library, apparently I have created an OCX but it requires a form but the VB.net program is a class library.
How can I create a dialog as a DLL ? I have a SDI MFC app (CView is based on CFormView) and from a button I want to load a modal dialog, but that dialog must be developed as DLL ... I didn't find something that fit my needs on internet ... P.S. I have only VC6 !
how to create, initialize, and maintain a memory device context that works as a local buffer for images? The idea is to maintain some large images in local DCs and bitmaps, and only bitblt them to screen in OnDraw().
What I did so far was was to define CDC and CBitmap objects as members of my View class, and then tried to initialize them with the sequence that begins at "// Initialize buffer". I placed that sequence in either OnInitialUpdate, or PreCreateWindow, or OnPrepareDC, or the view constructor, to no avail. The code always crashes in OnDraw, and I've noticed that the m_hDC member of myDevice is zero at that point.
Obviously, the initialization is wrong and MFC does (too many) things in the background which I'm not aware of.... My question was where can I read about that?
Code: class CMyView : public CScrollView { // ... CDC myDevice; CBitmap bmp; CBitmap *oldbmp;
How can I create MS Word 'print layout' like interface. The attached picture says it all. Basically I want a shaded area around my document just like word so it gives a feel of the 'page'.
I was hoping I can override some function somewhere and along that lines tried playing around with below but that didn't work.
Code: BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs) { if( !CFrameWndEx::PreCreateWindow(cs) ) return FALSE; // TODO: Modify the Window class or styles here by modifying // the CREATESTRUCT cs cs.cx = 250; // just playing around with size cs.cy = 250; return TRUE; }
How can I implement the paradigm demonstrated by the code below to run on WinXP?
I want to fork a process or create a thread that shares global variables with the parent process/thread.
The child process/thread monitors the progress of the parent process/thread.
I cannot find documentation for a fork function per se, a Unix term. It might be called something different for WinXP.
I would be happy to use threads instead. But I'm rusty even with Unix application threads; and I know nothing of WinXP application threads.
So any turnkey implementation that demonstrates the simplest use of process or thread functions for my purpose demonstrated below.
In either case, do "forked" processes and threads share global address space in WinXP, as they do in Unix?
I would prefer to avoid the overhead of IPC mechanisms. The "overhead" includes my own relearning curve.
The GUI screwed up my indentation. I would try to correct it. But the proper indentation appears when I edit the posting. I suppose I need to insert real tabs. Haven't figured out how (yet).
Not even real tabs work; and I cannot get the "paste as text" button to behave as I expect. What is the trick for posting indented text in this GUI?
#include "stdafx.h" #include <stdlib.h> #include <Windows.h> long curCount; int isRunning; int _tmain(int argc, char* argv[]) { curCount = 0; isRunning = 1;
I am wokring on a project that has used an MFC DLL in conjunction with Outlook to send and archive mail. I need to be able to create folders for integration from an older mail system. I have looked online to see if there are examples in C++ (since I have to modify the existing C++ dll to include the funcitonality). I realize it is much simpler using VBA or C#, but I am limited with my choice. I essentially want to use the MFC type lib for Outlook 14 and use the CMAPIFolder,CFolders create folders in the Inbox.
here is a sample of the code: //I have included the necessary header files COleVariant covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR); //start outlook if (!olApp.CreateDispatch(_T("Outlook.Application"), &e))
