I am trying to add labels to the data. I have data in a file divided by space:
1 2 3 4 5 6
7 8 9 10 11 12
I need it to look like this:
label_1: 1 2 3 4 5
label_2: 6
label_1: 7 8 9 10 11
label_2: 12
How can this be done?
I have a file that can range from 100 rows to 10000+ that is comma delimited with 8 columns. The first 32 rows (also comma delimited) will always be ignored (geographical header information). I will be wanting the data from column2 and column3.
For this I believe I would need (2) For Loops as such:
for(i=0;i<2;++i) {
getline("do something here");
}
and
for (i=0;i<3;++i) {
getline("do something here")
}
Also would using a vector or array with dynamic storage be the better way to tackle this problem? Where to start from after accessing the file.
Given an array of angles A = [0 30 60 90 120 150 180 210 240 270 300 330 360]
Write a program that will generate the data set of angles automatically and provide three columns; sin(angle), cos(angle), tan(angle). Make this program as compact and readable as possible.
I am trying to make a table class that will be able to have multiple columns of data. I want it to have something to hold data (I was using a 2D vector for only one data type) in it, somewhat like a pair, but for any number of data types. The class is a template to make it generalized.
I have looked a little at variadic templates, but I don't know how to declare the vectors for each data types then.
Basically for homework, we gotta make an array of payroll objects, using the general format I've made below...
I'm having trouble. The .dat file we are given to test looks like this:
40.0 10.00
38.5 9.50
16.0 7.50
42.5 8.25
22.5 9.50
40.0 8.00
38.0 8.00
40.0 9.00
44.0 11.75
When I execute the program, it shows the first column of objects, but will always replace the 2nd column values with a 0.
It's definitely NOT reading that column, and using the constructor to set it to zero. I don't know why it's not reading that column though...
(TL;DR.... Currently it reads "Employee #1: 40, 0" rather than "Employee #1: 40, 10.00"... etc)
Here's my code.... (not 100% done yet just testing datafile output atm)
#include <iostream>
#include <fstream>
using namespace std;
class Payroll {
private:
double payRate; // holds an employee hourly pay rate
[code]....
I want it to read the other column without giving me zero />
I'm dynamically creating some labels. This code creates them OK.
panel1.Controls.Clear();
for (int i = 0; i < 5; i++) {
Label label = new Label();
label.Top = (30 * i) + 20;
[Code] ....
Now, after I'm done with them, I'd like to delete them but my code below skips each of the two forloops, so nothing happens. The labels are still on my form. When I debug into this code, I stop on the first forloop and then I step but the flow never goes into the forloop. It jumps to the next forloop where the same thing happens.
List<Label> itemsToRemove = new List<Label>();
foreach (Label label in Controls.OfType<Label>()) {
if (label.Tag != null) {
[code]....
How you can touch a datagridview and it would insert the name it has for a product into a label or textbox.... As I have looked all over and I can't really find a proper way it is mentioned or maybe I am not applying it correctly.
View 4 Replies View RelatedI'm attempting to write a program that displays an array of labels; however, I can't seen to make the labels appear in the form. I've set some of the properties, but still not luck.

The program is when a person clicks a button this button updates 2 separate listbox one tracks the total rolls the other displays the total amounts of frequency afterwards adjusting labels as a scaling measurement.
The problem I am having is right at the end where I am trying to adjust the width of the label this is what I have. It is highlighting the word "Items" for each label and says that Non-Invokable member 'System.Windows.Forms.ListBox.Items' Cannot be used like a method L2 is a label. Additionally I have added in the information for one of my loops below the line I am having trouble with this loop is created to determine how many lines are in the listbox of rolls and I have no trouble with this just thought id add it for additional information I dont think I need to add the rest of the code but I can if needed.
L2.Width = int.Parse(lstfrequency.Items(0).ToString());
TL = 0;
for (I = 0; I <= 10; I++)
{
TL += int.Parse(lstfrequency.Items[I].ToString());
}
lstfrequency.Items.Add(TL);
I have a WPF grid made out of labels with two rows, Apples and Oranges currently without any information. Let's say I want to populate the grid to look like the picture below.
I was wondering what's the best way to populate the labels with a list or array? I was thinking about using a list and passing values into the list
E.g.
List <string> ApplesList = new List<string>();
ApplesList.Add("Red");
ApplesList.Add("Delicious"):
List<string> OrangesList = new List<string>();
OrangesList.Add("Orange");
etc...
But I was wondering it make sense to use a list. Or should I just use an array or 2D array?
Sometimes I wonder when would be best to use a list, array, or 2D array.
Is there such thing as passing a winforms label by reference? For example, can I create a pointer label and pass the address to a function? I've looked online but couldn't find anything. Perhaps that's a sign?
View 1 Replies View RelatedI am attempting to create multiple labels in a for each loop for each tag text (using htmlagility pack). My current code only creates one and doesn't change the first value (Which is AAE). I am using the labels to later input all the label.text into a database after the initial loop has finished (not shown).
foreach (var tag in tdTags) {
MessageBox.Show(tag.InnerHtml);
Label label = new Label();
label.Name = "contentName" + tag.InnerHtml;
label.Text = tag.InnerHtml;

I have this code it sums the rows now I need it so it would sum all the columns in the output and put it in row 8 of the outcome. How would I go about doing that?
Code:
#include Code: "stdio.h"
#include "stdafx.h"
int main(void) {
int number[8][7];
}

I have this code down except I'm very confused how to make the output come out in 3 columns.
#include<iostream>
#include<fstream>
using namespace std;
int main() {
int i, j, n, flag = 0, prime_number = 0, temp;
cout << "Enter first prime numbers that will be used or -1 to end:" << endl;
[Code] ......
My output right now is:
Enter first prime numbers that will be used or -1 to end: 20
Twin Prime Number : (3,5)
Twin Prime Number : (5,7)
Twin Prime Number : (11,13)
Twin Prime Number : (17,19)
But what I want is:
1. {3;5} 2.{5,7} 3.{11,13}
4. {17,19}
how to make the it all work later...but in the mean time how can i get this to display this? Note it has to be made using as a console program. The "Description" and "Cost/ib" collums will be referenced through use of a header file. all else is done by user input and calculations.
View 2 Replies View RelatedI'm working with arrays and I get them column by column and need to print them. I as there a way to print in columns?
For example: I produce an array of A, B and C from a loop and then need to print them in one column and the go to the next column ....
so in the end I shall have an output like this:
A E
B F
C G
D h
... ...
My arrays are too long (over 50K) so I cant just store the arrays and then print them. I need to produce each column array, print them and delete it and go to the next column.
I have a basic question regarding 2d vectors. The following code makes a 2d vector and fills it with a matrix of integers. The vector tempVector3 gets added as a new row to the matrix. But what if I wanted to add the tempVector3 as a new column instead. How would this be done in the simplest way?
#include<iostream>
#include<vector>
int main(){
std::vector<std::vector<int>> numbers;
std::vector<int> tempVector1;
tempVector1.push_back(2);

I'm having trouble trying to get my loop program to display multiples of 4 in rows and columns. My objective is to print multiples of 4 that are less than 100 in a 4 by 4 format.
So far when I write the code I get 4 8 12 16 20 .... 96 all on the same line.
This is what I expect the code to look like if done correctly.
4 8 12 16
20 24 28 32
36 40 44 48
52 56 60 64
68 72 76 80
84 88 92 96
This is code that I have so far.

Ok so I'm working with a windows form in C# and sql server database. I'm trying to do something like what is in the image below using a datagridview. My question is how do I 1) ensure only 1 checkbox is checked per row 2) do math that 'links' a checkbox column with another column, and add the totals. I understand that asp.net and web forms would be easier but we have not reached that point in the course yet. Would this be on the right track:
foreach (DataGridViewRow row in dataGridView.Rows)
{
if ((bool)(row.Cells["Checkbox"]).Value || (CheckState)row.Cells["Checkbox"].Value == CheckState.Checked)
{
// Do something
}
}
Attached image(s)
My output right now is:
Enter first prime numbers that will be used or -1 to end: 20
Twin Prime Number : (3,5)
Twin Prime Number : (5,7)
Twin Prime Number : (11,13)
Twin Prime Number : (17,19)
But what I want is:
1. {3;5} 2.{5,7} 3.{11,13}
4. {17,19}
else if (i - prime_number == 2)
{
cout << "{" << prime_number << ";" << i << "}" << endl << endl;
prime_number = i;
}
So I made a text file which goes like this
word word word word
word word word word word word word
word word word word word
word word word word
(word is actually word I just didnt type them)
Now i figured out how to get the rows to work
#include <iostream>
#include <fstream>
#include <istream>
#include <stdio.h>
int main()
{
FILE* fp;
int countLines = 1;
int i;
[Code]...
I cant figure out column to work... Is it the same method cause im getting confused a lot!
How i draw such a thing in .TXT file using file handling. This output must be in columns and rows and in well arranged form.

How can I read just the first column of this from a text file?
ORG 100
LOAD X
ADD Y
STORE Z
HALT
X, DEC 49
Y, DEC -80

I have
while (! sourceCode.eof() )
{
getline(sourceCode,symbolValue,'

Here's my code for adding the rows and columns. My problem is that my program displays an incorrect output.
main() {
int a[20][20],r,c,y,x,sum=0,rn,cn,cs=0,rs=0;
cout<<"Enter number of columns : ";
cin>>cn;
[Code] .....
This should be the output
Enter number of columns: 4
Enter number of rows: 3
Enter twelve numbers: 9 2 3 4 2 3 1 2 5 6 7 8
The numbers are:
9234
2312
5678
Sum of number 1 column is: 16
Sum of number 2 column is: 11
Sum of number 3 column is: 11
Sum of number 4 column is: 14
Sum of number 1 row is: 18
Sum of number 2 row is: 8
Sum of number 3 row is: 26
