I am a beginner of c#.. i have try to made a windows notepad and face some issues. I want to add find string from open file... and also want to replace it with a new string... Is there any simple and easy solution to this problem??
View 7 Replies I'm undertaking a project at the moment which requires me to hook into a custom c++ application from a Java applet via JNI. The c++ application needs to communicate with MS Word and potentially other office programmes in order to highlight text and offer find/replace functionality programatically. The idea is that when the applet is launched, it will communicate with the C++ methods to hook into an open MS Word document and highlight all words that start with the letter 't' for example.
I'm concentrating on the C++ side of things first . Even some basic access to an open word document would give me a great start!
I have to develop a C program that reads a very complex txt file (output of a calculation code, so full of mixed text and numerical tables), search for a specific table in it and individuate/print or replace a specific value with assigned position in the table.

But it just keeps the textbox empty.
I am new to C, but I recently completed an exercise from a book that finds a string in another string, removes the string, and replaces it with another string.
Code:

bool replaceString (char source[], char s1[], char s2[])

Is there a way to replace 3 char's in a string. For example i have a string containing
s = "The school is called 7x8"
I want to replace the "7x8" with "LSU". But the "x" can be any letter or number.
Is there a way to do that ?
I have an open file dialog that opend the xml file and store the path to the textbox, it returns the path correctly but when i need to store that xml file into the database it tells me that there is an error next to '' because when i try to debug it it gives me "C:\Student Results\FC2015.xml" this results then it breaks. here is my code:
This code returns xml path to textbox
OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "XML Files (*.xml)|*.xml";
ofd.FilterIndex = 0;

I'm having a bit of problem. I've set the string 'Absent' to all student in a file. However, I want to replace 'Absent' with 'present' when the correct ID assigned to a student is entered. In other words, 'Absent' will only change to 'Present' for a specific person at a time. I'm not sure how to implement this

To replace a string in my file with another. The file contents look like the following:
abc 123 0
"abc"= The username
"123"= Their password
"0"= The amount in their bank
I want to change their bank amount.
But, it isn't working, nor is it even giving me an error code.
// When the user logs out, make changes to their bank
string strNew = std::to_string(player.bank); // String representation of the revised player bank

and so on..
no i want to find the 44,495 in this textfile.. calculate a new value like 44,495 x 2 + 5
and write the same file as
Pizza 23232

"C++ is a general-purpose programming language." I have to find the word "C++" and replace it with "Java" and then capitalize all letters.

I'm creating simple console application using Code::Blocks to allow me to pass parameters from other application to replace string within text/registry file before execute the registry merge. Passing parameters to console already success. Now I only have problem with reading file. Example of first line in the registry file is as below.
Windows Registry Editor Version 5.00
However when read into string and output to console using 'cout', it will be show as below with spaces in between.
W i n d o w s R e g i s t r y E d i t o r V e r s i o n 5 . 0 0
Below is my code.
ifstream f("install.reg");
string s((istreambuf_iterator<char>(f)), istreambuf_iterator<char>());
cout << s;
I should state that I am recently new to C programming. I have dabbled with Python in the past, but nothing formal. I am taking a C programming class, but it is an introductory course. As such, the instructor is moving extremely slow through the material.
With this program, I am trying to search a given text file (line-by-line) for user-submitted data. I then want to be able to store which line that data was found on. The program runs, but it always results in "Sorry, couldn't find a match." Even if it shouldn't.
Code:
#include <stdio.h>
#include <conio.h>
#include <string.h>
#include <stdlib.h>
}

I should probably explain my overall goal with this program.I would like to write a program that will calculate the molecular weight of a compound. I expect the user entered molecular compound to be something like this: CH3COOH (An equivalent entry could be C2H4O2)Also, it needs to be case sensitive because the chemical formulas are case sensitive.
The output will be "The molecular weight of CH3COOH is xxx.xxxxx grams".I have two text files as well. One contains a list of all chemical symbols, and the second is a list of all atomic weights in the same order as the first. I want to place the user inputted data into an array, then search for each element of that array in the chemical symbol text file. It will show which line it was found on, then I can use that line to grab the atomic weight from the second text file.
i have a work to do that consists on a given char pointer to a chain and a also given char pointer to a string. i have to search that chain in the string, and return the position where the beginning of the two it's equal. but only if they are equal.
example: string is "abcd" and the chain is "bc". want to find the chain, and if it exists, the position return will be 2. in the work it says that we should use sprintf() too. here is my code, which is incomplet yet.
Code:
char* pos(char* C,char* S){
char *str = S;
char *chain = C;
int i, j, temp;
int lengthStr = strlength(C);
int lengthChain = strlength(S);
}
[code]....
my doubt is how to use sprintf() and where. if i have to use malloc() and free(),
other examples:
pos(AGA,CTGCA)
return:
0
pos(AGA, ATAGATA)
return:
3
pos(AGA AGATAGA)
return
1 5
I'm trying to use the biSearch function to search for a keyword in the dictionary.

printf("%s=%s
",DictEntries[mid].key,keyword);

I am working on a project which is a fairly simply BAC calculator. I am attempting to grab data from a text file, which contains state abbreviation, maximum BAC before aggravated, and minimum license suspension. The text file looks like
#include <iostream>
#include <fstream>
#include <string>
#include <cmath>
#include <stdio.h>
#include <ctype.h>
#include <iomanip>
#include <algorithm>
#include <cstdlib>
#include <sstream>
using namespace std;
float MALE_RATE = 0.68, FEMALE_RATE = 0.55, LEGAL_LIMIT = 0.08;
//percent of body weight which holds alcohol
[Code] ....
The code I am struggling with is the getline and stringstream which is near the bottom.
The output I am getting is
The maximum BAC before aggrevated DUI in AL is .15
The minimum penalty in AL is 90 day suspension of license
I get that for every state I type. I know it is reading the first line, but something in my code does not allow it to read the other lines
i'm doing a validation exercise program. Just a question, how do i search an inputted string for a certain character?
For example:
Hello.World
I wanna determine and find out the where the '.' sign is.
I'm doing an if-else conditions, i need to determine where the character is located and make sure it doesn't repeat.
Code:
#include<stdio.h>
#include<string.h>
#define MAX 25
int main(void)
{
int ch;
[Code]....
i think that cause this program to be error.because when i using the reference from internet, the program was executed for sure.This code what i mean
Code:
#include <stdio.h>
#include <string.h>
#define MAX 10
int main () {
int ch;
char str[] ="This is a simple string";
char str1[MAX];
char str2[MAX];
[Code]....
and rather than that i didnt have anymore idea to make that replacing string.
So basically here I have a menu in my C program and if I were to select option 2, I would enter a string up to 30 characters and it would output each block of 16 bytes should be shown which contains a character in the requested string. However, when I compile and run the program and search for the string, nothing happens. what I may be doing wrong?
Code:
else if (select == 2){
printf("Enter a string of up to 30 characters: ");
scanf("%s", &userstr);
//Compares both user's string and file string
for (i = 0; i < size; i++){
if (strcmp (buffer, userstr) !=0){

I need to search for a string in an array of objects, this is what I have but it does not seem to work, it always gives me the second string in the array instead of the one that i search for.
void binarySearch(Student S[], string name) {
int first = 0;
int last = 9;
int middle;
int position = -1;
bool found = false;
[Code]...
I understand that the strrchr function is supposed to search for a string from the reverse. Unfortunately, mine isn't doing that.
#include <stdio.h>
#include <conio.h>
int main() {
char userinput[100] = "null";
char searchchar;
char *s;
char try_Again;

I need it to search a dynamic array which I build from an input file. When it finds the user-input string, I want it to store the line number, and continue searching, and record all lines that contain the user-input string.
Here is a link to my complete main.cpp, header file, and implementation file. The function I am having trouble with is "Bagger::lineSearch"

How would you search in a vector array from a user input string?
ex: user input : "Hello"
output: search vector array and find the line that has the string "Hello" and output the array "Hello" is on?
