C# :: Searching Through A RichtextBox For Specific Words And Display It?
Dec 28, 2014
I am building a c# application that would be able to search for specific words and display the frequency of each match and their respective values.All these is done by uploading a file into a rich texbox then read through it ,I have it uploading a file and read it and count the words but I cant get to search all the words at the same time in the richtextbox say I have RE3409RT,RE6789GH,DG7654YU,I want to go through all these codes and give how many times each occurs is working and when I specifically declare it say string srch="RE3409RT";
Find below is my code so far.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
[code].......

I need to create code based upon the following pseudo code:
dictionary=vector
file containing words to search for=external file
While there more words to search, for search the dictionary if the entire dictionary is searched and the word is not found, return the word, search the dictionary for the next element (and so on)
I cannot for the life of me figure out the sequence of loops to do this. The following code returns all of the words instead of just the ones not found in the dictionary, but it's all I've got after countless changes:
#include <iostream>
#include <fstream>
#include <vector>
#include <string>
using namespace std;
int main() {
string dictword;
ifstream dictionary;
[Code] ....
And it returns every word in the external file.

So a user inputs an artist name, and then if the input matches one of the nodes containing the artist names i need to return that. but then also if the input does not match any of the nodes, I need to insert a new one. This is to be written in C. Also my structure that this function goes off of is shown below as well.
Code:
artistNodePtr findOrInsertArtist( artistNodePtr *sPtr, char *artistID ) {
artistNodePtr newNodePtr;
temp = sPtr
if(temp->artistName_p == artistID){

I am having a problem printing out the results for my code, It is supposed to print out the largest and smallest value in the array, but keeps giving me a value not entered and I don't know why.
//This program lets the user enter 10 numbers and then display the highest and lowest number.
#include <iostream>
#include<stdio.h>
using namespace std;
int main() {
const int NUM_ENTERED = 9;

It's my understanding that there are three ways to go about updating a control on a form from a class.
A) Instance the form, eg: Form1 Frm = new Form1();
The problems I have run into with this is that while writing text to a richtextbox using the instance Frm, the richtextbox never updates on the form.
B) Passing the object to the class.
This method seems less used and can be very problematic. Haven't looked into it thoroughly.
C) Exposing the objects using classes within the Form.
While making methods public they still do now show as available for use when calling from classes, unless I instance them but then I run into problem A. I've considered making the methods static so no instancing is required but when doing so the object(in this case richtextbox) becomes invalid due to itself being instanced by the automatically generated code when adding the object.
I know there is another way to pass values then force the object to update but that won't necessarily work with a richtextbox as you have the option to deal with color and font variations.
I imagine I'm missing something pretty simple here but I can't find any resources online about how to handle objects with more complex data than just straight text.
Example of problem A
//called from a class
Form1 Chat = new Form1();
Chat.BeginChat();
Chat.AddChat(Color.Lime, "Testing");
Chat.EndChat();

I want to load a file to rich text box component. I have this line:
richTextBox1->LoadFile("StudentaiRez.txt", RichTextBoxStreamType->PlainText);
But I get an error when I try to pass second parameter. It says : type name is not allowed.
I probably write it wrong, but I can't remember the correct way. In examples I only see that instead of -> dot is used, but it doesn't work either.

I am creating a simple log parser (loads a text file and filters out unnecessary information, but has the option to show the full log) and I'm running into an issue with fairly large log sizes (50+mgs). I have seen a few recommendations from a stream to memory manged files and even alternate 3rd party controls.
I foresee a few issues with any of the non-third party solutions (which I would prefer to avoid third-party add-ins) such as the scroll bar not correctly reporting the relative length or position of the complete text in the box (when displaying only a portion of the file at a time) and in the stream solution where you read on scroll (as necessary) have not only the same issues, but how do you resume reading in the middle of the file? This also all assumes I would be periodically clearing the RichTextBox to keep the memory usage down to avoid an OutOfMemoryException (which I have been running into.)

I know this is more simple than I am making it out to be. I have a solar panel hooked up to an 8-Bit ADC and linked into my Microprocessor. I am trying to take the Binary readout from the ADC and convert it to a decimal number to be displayed on the boards LCD display. I am wiring the ADC to PORTA on my Motorola Freescale Board. This is for a final project for my electronic systems class due on Monday...

My .csv file is like:
Bone,origin,deep/superficial,location, action.
with list of 38 bones.
This is my main.cpp:
#include <iostream>
#include <fstream>
#include <sstream>
#include <vector>
#include <cstdlib>
#include "Action.h"
#include "Action.cpp"
[Code] .....
For action, if user enters action, it will output the bones involved with that action.
For strengthening, if user enters location, it will output bones involved with that location.
For dagnostic, if user enters bone, it will output location of bone and whether bone is deep/superficial.
How I could search in csv file for these.

WPF window I'm working on. I have a window that has a textbox to enter a name to search a database table for, and when the search button is clicked, the ID for that username will be returned to a separate textbox. The code I've written atm doesn't seem to be working, but it looks fine to me. Here's what I've got;
private void btn_SearchUsers_Click(object sender, RoutedEventArgs e)
{
if (!string.IsNullOrWhiteSpace(txtb_SearchName.Text))
{
SqlConnection sqlCon = new SqlConnection(conStr);
[Code] .....
So, I have the value entered into the textbox to be searched for stored in a variable, I'm selecting the ID from the table when the name in the variable is found, storing the result in a DataTable, and then in my foreach loop, if I find the name (the name column being index 1 in the table), I set set the ID result textbox to equal the ID for that name (the ID column being index 0 in the table). I think the foreach part is what's throwing me off. Maybe the column stuff? My Users table is like;
ID Name
1 John
2 Roger
3 Mike

I am trying to write a program to search a library file with the name of a book or author and return the books that match the searched string in some way. For instance, if I search "Develop" it should display Game Development Essentials(Novak) and Developing Games in Java(Brackeen) and tell me that 2 records were found. Currently, it shows all the records regardless of what i search for, even if it is jibberish. Am I missing something in my functions? should I include the code that accesses these functions?
//If the user chooses A or a
int showBooksByAuthor (int count, string name)
{
char choice;
int index = 0;
}

I have a multimap with over 300k entries defined like so: std::multimap<std::string, std::string> filedata;
Using the following code and std::multimap::equal_range, I am able to successfully search for a word in the multimap and get needed data:
// Data with strings.
data = std::vector<std::string>();
// Get iterators to matched pairs.
std::pair <std::multimap<std::string, std::string>::iterator, std::multimap<std::string, std::string>::iterator> dat = filedata.equal_range(word);
// Go through each matched pair and get needed info.
for (std::multimap<std::string, std::string>::iterator iter = dat.first; iter != dat.second; iter++) {
data.push_back(iter->second);
}
Now, I would like to search the multimap using regular expressions (EX: std::regex("[a-z][a-e]h")). What is the fastest way to do this? Example code may look like:
std::pair <std::multimap<std::string, std::string>::iterator, std::multimap<std::string, std::string>::iterator> dat = filedata.equal_range_with_regex(std::regex("" + word + ""));. Pseudo-code / algorithms will be enough.
