I am creating a student management system (using classes) for my assignment and am stuck with designing UI. I made the classes but am not sure what the best control is to display items from a Dictionary<> object. Right now I am using the ListView because of the columns in details view...just want to know if there is a better, simpler control I could use if i want to display data (without using sql)...or is the good old "next" and "previous" option the simplest?
I am now making a Dictionary using C++. My goal is to search the word and display the definition of the searched word from the text file. I have a code but it is not working. How can I search a word and display the definition of the word from a text file?
I'm trying to use a listview component to show all the fonts on my system, and display each item (row) in the actual font design.
When I run the following code, nothing displays in the listview.
If I rem out line 4, then the list populates with all the fonts, but of course, in the default listview font.
I thought I read somewhere that each item in a listview can be set to a different font.
int i = 0; foreach (FontFamily oneFontFamily in FontFamily.Families) { listView1.Items[i].Font = new Font(oneFontFamily, 10); listView1.Items.Add(oneFontFamily.Name); i++; }
someList.Clear() and var keysToRemove = new List<string>(); foreach (var e in someList) { keysToRemove.Add(e.Key); } foreach (var key in keysToRemove) { someList.Remove(key); }
And keep getting the error: An item with the same key has already been added. I'm using VS 2012.
Anyway, I am working on a project and have compiled a dictionary text file of english language words. I want to use this dictionary for an autocomplete feature that I would like to add to the program.
I am having trouble finding anything about either 1) an autocomplete library I can #include into my code. 2) how to write my own.
I need it to be in either C or c#. If i can get the algorithm in C then I can just convert it to c#
how to see if what the user says is in the dictionary. I do not know what to put in ContainsKey() or after the information in console.writeline. I just want the user to type in the key then see if it is in the dictionary then print out the value if it is.
while ( Console.ReadLine() != "exit" ) { Console.WriteLine("Type in word"); if (clothingDictionary.ContainsKey()== true) { Console.WriteLine("key is {0}, value is {1}", );
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;
A friend of mine is taking classes currently and using open office. He asked if I could create a program that would spell check medical terminology. He said that he has a program that works with Microsoft word but it will not work with open office.
I am having trouble getting values of a dictionary to display in a label and radio button text after the dictionary key is randomly selected.
I first created a class called TheoryQuestions and created a new instance of the class for each dictionary entry. Each entry contains strings for Question, RadioButton Text(x4), and Correct Answer.
The random generator is actually selecting a random number as I can display the generated number in a label. The problem is that the dictionary string values held in the dictionary position represented by the random number are not being displayed.
Here is my TheoryQuestion Class
public class TheoryQuestion { bool BeenAsked = false; public string Question { get; set; }

Its probably some mistake I have made but I just can't see it.
There is no content when i search word in the dictionary.txt....this is my example of dictionary.txt...in the add case it is working,,only in search case...
I need to assign unique integer values to words in a dictionary that have the same alphabets, for example 'act' and 'cat' should have the same integer value. Would just adding the ascii values of the letters be sufficient?
I have a script that checks and compares two lists from an offline dictionary. Dictionary.txt which has a lot of words in it. input.txt will compare to dictionary.txt and print out anything that matches in CMD.
However, instead of using an offline dictionary is there anyway to make a code check an online dictionary? If so, would this process be slow or fast?
So I'm rewriting an old project of mine, and I'm trying to determine if there's truly any better way to map the data taken from a text file "dictionary" into the correct class fields for further processing. For example:
In each of these, I'd need the "value" (MY_FIRST_NAME, MY_LAST_NAME, etc) from the "keys" (FNAME, LNAME, etc) to be mapped to the proper class fields. Say, for example, I had this:
Class DataProcessing { public string Address; public string FirstName; public string LastName; public int TotalCalls; ... }
I would need DataProcessing.Address to be set to the value in the ADDR key/value pair. The same would be true for each other field. The problem is that based on the text file's source (which isn't under my control, and won't be changed anytime soon), the key/value pairs are not always in the same place...so a second file could have the data as such:
TOTCALLS=47 ADDR=123 SOMEWHERE LN, NOWHERESVILLE, TX 01234 LNAME=DARKPOETCC'S LAST NAME FNAME=DARKPOETCC'S FIRST NAME
Any smarter way to do this than looping through each line that was read in from the file, and determining where it belongs, such as (pseudo code follows):
IF FieldName == "TOTCALLS" THEN //Assign to TotalCalls field ELSEIF FieldName == "ADDR" THEN //Assign to Address field ELSEIF FieldName == (You get the picture...) //Do thing N_Field
Over the last few days, I've been trying to implement a spell checker in c++ that checks if the inputted word is in the dictionary file on my computer. However, as I'm nearing completion of the project, I keep running into more and more errors, some of which I do not understand. My program is complete, albeit, with some minor bad practices (I hard coded a few things just to get the program up and running.For some reason, everything works well until I output spelling suggestions. I type in "mses" (attempting to spell mess) and it returns some strange characters. It does definitely recognize that there are two permutations that match words in the dictionary (however they are both mess due to the algorithm implemented), and I don't understand why? I will work on removing the duplicates after.
// Spell Checker.cpp : Defines the entry point for the console application.//
It's compiling ok, and displays the first call to the printf function from main. However, after this I get the 'Segmentation fault (core dumped)' at the terminal, presumably from the call to the dictionarySort function.
I had a little look around and found it is something to do with non-existent or not available memory addressing, I think? Even so, I can't figure out what is causing the issue in my code.
I created class called students which suppose to store students names of in array but when I call the display function it display only the first name. but I want it to display names depending on the array size.
#include <iostream> #include <sstream> using namespace std; const int SIZE=5;
JSONNode::const_iterator iter = root.begin(); for (; iter!=root.end(); ++iter) { const JSONNode& arrayNode = *iter; std::string type = arrayNode["type"].as_string(); if(type == "node")
[code]......
But when i try to ptint id of second item std::cout<<"Item Id ->>>>>>>>>>>>>" << collection[2].GetId() << std::endl; it gets a blank value. but size of the collection is 82, get the correct value for the collection size.

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...
I do some research about getting the coordinates from the list items but without success. I would like to make that when i press down my mouse button that little blocks fall "out" my mouse and stack on top of eachother.
that first works. When i press the mouse button i draw squares and the fall to the bottom of the screen, but the stack part not.
here is my code:
using System; using System.Collections.Generic; using System.ComponentModel;
I'm working on creating a windows form with a listbox, textbox, and 2 buttons (add,remove). I need a way of removing every string matching the contents of the textbox from the listbox. Here's what I have:
for (int i=0;i<listBox1.Items.Count;i++) { //... listBox1.RemoveAt(i--) }
Seems to work, but I need a way to show a error message once the user clicks 'remove' and no items in the listbox match.
im new to programming and new to C, just started with arrays and im somewhat stucked, where i have a .txt file which contains items and prices. I want the items and the prices split into 2 different arrays
The .txt looks like that:
orange 0.89 banana 0.79 apple 0.59
I now want to split the items in a char items[100][100] and float prices[100]. how to split this, preferably with fscanf ?
