C# :: Creating Multiple Labels In Foreach Loop
Apr 29, 2015
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 know that where I have the intIndex++ line is wrong. It's just going to stop at the last index and call it good, but I don't know how to make it stop at the matching name. The only examples I can ever seem to find use the foreach loop to print out a value, and I'm clearly just not understanding this enough to make it work for me.
Instructions are:
--Declare a variable to store the result of the search, int intIndex;
--Use an if statement with the Contains method to check if the name in the search box is in the queue.
--If Contains is true, initialize intIndex to zero and use a foreach to walk through queue, else display a message that the name is not in the list.
--If a match is found use intIndex to select the matching entry in listbox and display a message indicating the name was found. Be sure to increment intIndex each time through the loop.
private void btnSearchByName_Click(object sender, EventArgs e) {
//delcare int variable to use as the index for the list box
int intIndex;
//If Contains is true
if (cstrName.Contains(txtSearchName.Text))

I'm new to C#. I'm trying to create a program to audit some of our processors. As you will see below, I have two foreach loops that allow me access to errorOrders(returns <<UserName, #of errors>>) and totalOrders (returns <<UserName, #of totalOrders>>).
However, the problem i'm running into now is that it seems to constantly loop through these two ForEach loops. When i run it, the 'count' on both errorOrders & totalOrders is 38. The program loops through all 38 users just fine, but then it continues to loop through users again...re-doing the process that it just finished.
I'm looking to see if there is another way I could set this section up so that it only loops through users once. I was thinking about trying to create a 'Boolean flag' that would force the program out of the ForEach loop after it has run through all the users...but i'm sure there are other ways to handle this.
foreach (KeyValuePair<string, int> error in errorOrders)
{
foreach (KeyValuePair<string, int> total in totalOrders)
{
[Code]....
I know i should probably seperate these two foreach loops instead of having them nested..however, the problem that arises once i do that is my errPercentage can not be calculated if i do.

I am trying to create n number of files (n being an integer), by passing the name through a character array (and obviously changing its value at each iteration). But the problem is that the program compiles and executes but not a single file is created.
Here is my code snippet.
void file_phipsi(int m)
{
int a=0,n=0;
char *str1;

I have a class that loads the contents of a XML file into their respective object types and stores those objects in a list. Each object has its own list of objects with properties the program will later modify.
The problem I am currently having is that after looping through the objects and modifying the necessary properties the modifications do not persist. This leads me to believe I am modifying a copy of the object rather than the object I think I am modifying. I am not sure why this is happening as I believe I should be modifying the object that is referenced in the collection.
What I have tried, I started using LINQ to get the object I am looking to modify. After a little more research I don't think this can work properly due to the LINQ query returning a new object(copy of the object). Currently I am using nested foreach loops which still are not behaving the way I expect as the properties I am setting are not making their way back to the original object.
The PopulateLogSheet() in the following class is where the problem loop is.
class ChillerCheckCollection {
public List<Chiller> chillers = new List<Chiller>();
public void LoadChillers(string filePath) {
var availableChillers = (from chiller in Xdocument.Load(filePath).Descendants("chiller")
select new Chiller
[Code] ....
And here are the other classes referenced in the above class.
class Chiller {
public IEnumerable<LogSheet> chillerLogSheet = new List<LogSheet>();
public int chillerID;

I thought I'd display my fun use of the new C++11 auto keyword to create a compile time foreach. It only works for STL collections, or anything that implements the STL collection iterator methods begin(), end() that return a STL iterator.
// Standard Template Library foreach
// element = iterator name
// collection = STL data collection variable
#define stl_foreach(element, collection)
for(auto element = collection.begin(), __end__ = collection.end();
element != __end__; element++)
}

for (int j = 0; j < nodesinx; j++)

T[j][n+1] = T[j][n] + 0.16 * (T[j][n] - 1[n] - 2[T[j][n] + T[j] + 1[n] ; //equation
n= n + 0.1 ;
cout<< "temperature" << T[j][n+1] << endl;

I am creating a binary search program that lets the user input up to 10 integers and then the program displays the array and sorts it. When the user is prompted to select an integer, if the integer is in the array, the program responds with the array subscript part. I can get the loop to work once and maximum twice, but then it wont search for the array or say value not found even though the number in in the array. I tried making the values NULL but that only lets me go through it one more time.
Here is my code:
#include <iostream>
using namespace std;
//Functions
void printArray(int);
void selection(int);
int binarySearch(int,int,int);

From the example given below, I would like to Generate a matrix who stores a generated array for each iteration. I have an understanding of inputting single elements to a matrix but how can I input an array to a matrix. let's say I would like to input and array of 4 elements that should be stored as a single row of the generated matrix and do this for an infinite while{true} loop.

I have this if block that is supposed to be creating a pipe then forking and I would like to combine the while loop below it with it. How would I do that?
p = pipe(pipe1);
if (p < 0) {
printf("pipe error");
exit(0);
} else {

My address book will be simple, and the thing's that I'm expecting to use in it are :
Pointers, Linked Lists
Malloc
Structs
Typedefs
Makefile, header file
Putting functions into different program files
I have started the program trying to create a struct, and getting it working with a couple of entries before going onto user input and splitting it up.
Code:
#include <stdio.h>
#include <stdlib.h>
int main(void) {
// Struct type address book. Just a name, a number and a pointer
[Code] .....
I'm a bit lost at this point... My knee jerk thought is to create a for loop, and cycle through the list.
I'm not sure how this would apply to this though? Without using the familiar type of print loop such as :
Code:
for (i = 0; ;i++) {
printf("%i
", array[i];
}
I'm thinking that I need to create a temporary struct that can be used to assign the value of the next struct in the list, and then somehow print from that....
I'll try and write the logic out :
while temp != NULL (The last node value is assigned NULL to show us where the end of the list is)
create a temporary pointer that can be used to keep track of where we are in the list.
print out the current entry name and number
then assign the temp pointer value to the * next of the current struct. So if we are in entry1 the *next should be the address of entry 2.
Print out entry 2 name and number, assign entry 2 next to the temp value.

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 am currently having problems creating a loop that will allow my user to choose to return to the beginning of the program or quit.
#include <iostream>
using namespace std;
int main() {
int j;
do {float a;
cout << "+----Welcome to Basic Operations----+
| Select Your Operation |
[Code] .....
I have not yet finished designing the interface for a couple of the operations, but right now i am hung up on trying to return to the beginning. I believe it is because the j was defined inside do and isn't carried out of the do statement for while.

I am trying to create a loop to call in the entries from the text file named Set. The entries of Set.txtare :
1 2 3
2 4 5
and so on .. (64 such combinations)[/CODE]
It basically means the first combination for testing is 1 2 3 and next has to be 2 4 5 and so i have 64 such entries defined in set
My test files are located in D://data// and are named tst_data1 to tst_data64.
I created a loop for test set but its incorrect
Code:
// loop for test samples
char basefilename[] = "D://data//";
char , testFilen[160], numiChar[10];
for (int i=1; i<=64; i++) {
strcpy(basefilenme, "D://data//");
strcat(testfilename, Set[]);
[Code] .....
How can i call the Set .txt and how to define it.

I am writing a program for grading a multiple choice test. The test data is pulled in from another file. My problem is that its only pulling in the first line of data and running an infinite loop without reading the next line of the data file.
My code is as follows:
PrintPurpose ( );
cout << student << " ";
cout << answers << " ";
inData >> key;

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?
