C# :: Extending The Width Of The Labels To Specific Value?
Jun 3, 2014
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 wrote a version of find_all() which searches through containers for matches and returns another container that holds iterators pointing to each match. When I compared what I wrote to what the authors of Professional C++ wrote, I found the two find_all() functions to be very different.Here they are:
//Mine
template<typename Iterator, typename Predicate>
std::list<Iterator> find_all
(Iterator front, Iterator back, const Predicate& match) {
std::list<Iterator> toreturn;
for(; front != back; ++front) if(*front == match) toreturn.push_back(front);

I'm trying to write an object oriented application framework. The programs can be console or GUI based, but I'm having some difficulty providing a consistent interface for outputting structures. The structures will be displayed by a variable description and its value. So, for a RECT structure the output on console would look like the following.
Code:
left 0
top 0
right 100
bottom 200
The numbers should be aligned next to their description. In console mode, white space must be appended to each description. In GUI, this extra process will not be necessary (some other processing might be, but it will be different).
The right way to display data in C++ is of course using a stream and defining the appropriate operator<<.
Code:
std::ostream& operator<<(std::ostream& strm, const RECT& r)
{
strm << "left" << r.left << "top" << r.top << "right" << r.right << "bottom" << r.bottom;
return strm;
}
Note that endl and the spacing has been omitted. This is because GUI output will also be implemented as a stream and they do not require a carriage return or padding. Should I define a StructStream object?
After I use the structstream object to store the output as a stream how should the output be written to the screen. Should I call cout from within the stream object. Should I have two buffers, one which borrows cout.rdbuf()? Should I call printf? Should I open another standard out file and use write? Should I convert the buffer to a string which will be display by cout or a winout? what I should do?

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'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) {

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.

I'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.
Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;

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?

I 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 am currently debugging this function. I am trying to make this function's width specifier align like a printf() routine. Here 's the code:
v Code:

bu_log(const char *fmt, ...) {
va_list ap;
struct bu_vls output = BU_VLS_INIT_ZERO;
if (UNLIKELY(!fmt || strlen(fmt) == 0)) {
bu_vls_free(&output);

Basically when I type in different widths and heights for the col and rows, the buttons that make up the width get cut off. Something is messed up but I'm not sure what!
InitializeComponent();
int _col = int.Parse(cols);
int _row = int.Parse(rows);
int width = groupBox1.Width;
int height = groupBox1.Height;
int bW = width / _col;
int bH = height / _row;

The problem says:
Define functions n(), s(), e(), w(), center(), ne(), se(), sw() and nw(). Each takes a Rectangle argument and returns a Point. These functions define connection points on and in the rectangle. For example, nw® is the northwest (top-left corner) of a rectangle called r.
I wrote below code for that:
#include <Simple_window.h>
Point n(const Graph_lib::Rectangle& r);
Point s(const Graph_lib::Rectangle& r);
Point e(const Graph_lib::Rectangle& r);
Point w(const Graph_lib::Rectangle& r);
Point ne(const Graph_lib::Rectangle& r);
Point se(const Graph_lib::Rectangle& r);
[Code]...
As you see, this just mark the top-left corner of the rectangle r. In other functions I need the specifications of that rectangle, for example its height and width. How to use these specs in those functions?

I am drawing two circle (inner circle and outer circle) using DrawElipse method. I have created two pen object named OuterPen and InnerPen and creating Outer Circle using OuterPen and Inner Circle using InnerPen. Problem that I am facing is that when I increase the size of outer pen lets say 10px then it overlaps the inner circle and inner circle is hide. How can I increase the size of OuterPen outwards and not inwards so that it don't overlap the inner circle?

I have this
Code:
#include <stdio.h>
int main() {
float number1, number2;
printf("Enter two numbers separated by a comma ");
scanf("%f,%f", &number1, &number2);
[Code] ....
When it prints the values, it prints them as I want. the problem is, what happens when someone puts in values with different width and precision? Here I had to write in the width and precision to display the values that are specified in the book. but what happens when someone puts in something that doesn't have those width/precision?
I end up with a lot of zeros after the number. initially I got 24.000000 (zeros are not accurate amount) I needed to show just 24. (with the decimal)
So I included %2.0f which gave me 24 (without the decimal point) what if some one put in 24.556. I got 25 as a result.
Does the width mean how many numbers in total including the decimal point and that is a minimum?

I have to output a series of data, I have to control the width of parts of my data. like following:
double a[] = {1.0, 2.0, 3.0};
double b[] = {1.5, 2.5, 3.5};
ofsteam myfile("result.txt");
for(int i=0; i<3; i++) {
myfile.width(5);
myfile << i+1 << " : " << a[i] << " - " << b[i] << end;
}
I only want to fix the width of a[i], b[i], but let the rest to be output normally.
how I can make it?

I derived a class from CRecentFileList in order to set the number of displayed chars for MRU.
The problem is that if I open the app with 256 set for this number (it is read from .ini file) the display is correct. But after I change it to 10 for e.g., File menu width remains unchanged altghough MRU are correctly displayed on 10 (or at least file name lenghts) chars.
how can I tell to the menu to shrink to actual width?

How to read and write an arbitrary number of bits from/to a file stream.
For instance, how to repeatedly read 9 bits from a file, then change to 10 bits, then 11 bits, and so on?
Obviously one way is by doing a lot of bit shifting, and masking. But honestly, I'm too dumb to get it right. Then I thought about using std::bitset and std::vector<bool>.

I m trying to load a png image by giving the dimension of my own.
CImage Image;
Image.Load (L"D:ImagesPNG_ImagesImage7.png");
But here what happens is that I m not able to give my own dimensions.My code requires constant changing of dimensions of the image.
I tried using libpng.lib in my code.But I dono the keywords for loading the png image after including the lib.
I m using Visual Studio 2010. I m developing in vc++.
How do I load and change the height and width of a png image?

I have created a program to calculate different measurements for a cylinder. Anyways, the end user has to input 3 variables.
Enter the lower radius: 6
Enter the upper radius: 5
Enter slant height: 2.236
The numbers are what "End User" would input. But I need to make it look like this when said "End User inputs the numbers.
Enter the lower radius: 6
Enter the upper radius: 5
Enter slant height: 2.236
Here is what I have for it, but I don't know what to put where.
printf("
Enter the lower radius: ");
scanf("%f", &lower_rad);
printf("Enter the upper radius: ");
scanf("%f", &upper_rad);
printf("Enter slant height: ");
scanf("%f", &slant_h);

How would I make it so that I can have someone input the length, width and height for all 3 boxes and then have it output the sum and average volume? Here's an example of what I would like:
INPUT - Enter Box 1 (Length, Width, Height): 10.1 11.2 3.3
INPUT – Enter Box 2 (Length, Width, Height): 5.5 6.6 7.7
INPUT – Enter Box 3 (Length, Width, Height): 4.0 5.0 8.0
OUTPUT – The sum of the volume is 812.806
OUTPUT – The average volume is 270.935
Here's my original code:
#include <iostream>
using namespace std;
double box(double length, double width, double height); // use double data
int main() {
double sum;
sum = box(10.1, 11.2, 3.3) + box(5.5, 6.6, 7.7) + box(4.0, 5.0, 8.0);
