C# :: Add Data Grid View Column To Listbox Using For Loop

I need to take a single column and all the rows in the column from a datagridview to a listbox using a for loop. My code is giving me no errors just not showing any data in the listbox.

// TODO: This line of code loads data into the 'enrollmentsDataSet.Enrollments' table. You can move, or remove it, as needed.
this.enrollmentsTableAdapter.Fill(this.enrollmentsDataSet.Enrollments);

i m working on a simple project, i want to populate my text boxes and comboBoxes through DataGridView, means when i double click on cell content then the text boxes are populated.my question is that if i have to populate comboBox with the specific value then what i have to do then because comboBox.selectedItem is an object but my class property is a string..
e.g
combobox shows 30 days in it and my class is Code: class account
{
public string day{set;get}
[Code]....
but that does not happen because "comboBox.selectedItem" is an object so if i have to do that what i have to do then?

I don't really have an issue with the math behind this, rather it's more with the code structure itself. Basically, every row is right, except for the last row. The last row (year) needs to be depreciated by the value at the beginning of the last row (year).

Basically I wanna make my textbox to contain only positive numbers. I was able to do that via masking and regex. I should let you know that the column is bound to a variable which is an int. Therefore, the user always have to type an int (no letters or characters). Like I said, I have been able to prevent user from typing anything but numbers.
Now to the problem:When the user leaves the cell blank and chooses to get out of that cell, they'd get "Input string was not in correct format" next to that cell.
-My approach is: whenever there is nothing in the cell, just replace it with 0. I have code that I thought will do that, but it wont. Seems like the cell was not null, because the if clause won't execute. This is the code:
private void gridView1_CellValueChanged(object sender, DevExpress.XtraGrid.Views.Base.CellValueChangedEventArgs e) {
GridView view = sender as GridView;
if ((view.GetRowCellValue(e.RowHandle, colPriority).ToString() == "") ) {
list.ElementAt(this.gridView1.FocusedRowHandle).priority = 0;
}
}
-Another approach is to change the display or the error message to like "Please enter a number." I have tried doing this but no luck. When I try this concept with the code below, it pops me a dialog box say "Do you wanna change the value?". I dont want it to pop up a dialog box. Also, i was looking for a message that I tried to give it. Looks like it doesn't even get in the if clause because I have checked. And its because its not null? I dont know. This is the code:
private void gridView1_ValidateRow(object sender, DevExpress.XtraGrid.Views.Base.ValidateRowEventArgs e) {
GridView view = sender as GridView;
GridColumn priority = view.Columns["Priority"];
if (view.GetRowCellValue(e.RowHandle, colPriority) == null) {
e.Valid = false;
//Set errors with specific descriptions for the columns
view.SetColumnError(colPriority, "Incorrect Value");
}
}
PS:I have checked that both of these methods get executed, so it isn't like they don't. I used some console.write stuff to check this.

I have a lstYourHand that has two cards in it, I loop through the listbox to get the values of both cards. I take the string value of the listbox item (strCardVal) and use a switch to give it an integer value (intCardVal). For some reason, when I run the code, the message Box at the end gives me the value 0 as a result, it does not register me giving it a value in the switch statement. My code is below:
Int32 intCardVal = 0;
String strCardVal;
Int32 intLoopCounter1;
for (intLoopCounter1 = 0; intLoopCounter1 == 1; intLoopCounter1++) {
strCardVal = lstYourHand.SelectedItem.ToString();

I'm trying to extract data from a grid, it's a Dev Express grid. I have got an object which if I hover over it in debug mode shows me the data I'm after. In the code below if I hover over "row" I can drill down through "Row" and then "ItemArray" and I can see the data I want in an array but I can't find how to get at it.
private void gridShowUsers_Click(object sender, EventArgs e)

Object row = gridView1.GetFocusedRow();
string [] rowarray = new string [50];

I am trying to complete this program and as far as I am aware, the only thing not working correctly is populating the listview with my data. I've been stressing over this for a few days and achieving no success. I have to load data from two text files (incidents.txt and technicians.txt), then use a query to populate a listview with all incidents that have been closed. Also, I have to use LINQ for this assignment, so I cannot change anything that would alter my use of that. I'm thinking that perhaps the problem is with my code in form1.cs?Included are all my classes,txt files, etc.

why filtering don't work??
This is code for load data into dataGridView
private void Izvestaj_Load(object sender, EventArgs e) {
connection.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:UsersTomyDesktopzadatak2zadatak2fedek_OldVersion(2002-2003).mdb;User Id=admin;Password=;";
dt = new DataTable();
OleDbDataAdapter sda = new OleDbDataAdapter("SELECT korisnici.korisnik,dogadjaji.dogadjaj,Tomislav.Datum
[Code] .....
And this is code for filtering by typing into textbox, when type nothing happening
private void textBox3_TextChanged(object sender, EventArgs e) {
DataView DW2 = new DataView(dt);
DW2.RowFilter = string.Format("dogadjaji.dogadjaj LIKE '%{0}%'", textBox3.Text);
dataGridView1.DataSource = DW2;
[Code] .....
And this is by filtering on dataPickers, range of date, and show me what happens on that dates, but show me exception when click button
private void button1_Click(object sender, EventArgs e) {
if(dateTimePicker1.Value>dateTimePicker2.Value) {
MessageBox.Show("Takav opseg nije moguc. Datum Od mora biti veci od datuma Do.", "Opseg datuma", MessageBoxButtons.OK, MessageBoxIcon.Error);

I'm working on an app which monitors user selected data sets from various devices, and I'd like to display the data in a CListCtrl. This would be very convenient, but I'm just a little concerned about (1) just how fast can a CListCtrl be populated, and (2) how can i reduce or eliminate screen flicker. To be specific...
1. There will likely be upwards of 100 rows of data, maybe more (probably 5 or 6 columns), and I'm going to have to refresh it all as quickly as possible, perhaps as fast as once per second. I can play games and only refresh a visible rectangle, but how responsive the control would be, having all that data deleted and refreshed continually?
2. You can see why I'd be worried about screen flicker, and I thought I'd likely have to make two identical overlapped controls so I could double buffer as I would with a graphic animation, switching the visibility of one or another control after its updated to give the appearance of sudden complete updates. BUT... I see there is an extended style you can set called "LVS_EX_DOUBLEBUFFER"

I've found that with streamwriter(sw) the data isn't displayed with the written to document until you either leave scope or use sw.close I'd prefer to keep sw open as I will be writing to the file in and out, sometimes very frequently, but would also prefer the data to be viewed in real time. Is there an efficient way of going about this?

I have a program which generates lots of data points in 2D (x and y co-ordinates). Perhaps 1,000,000+ of these points. These are floating point numbers. The values all fall within a specific range -R/2 and +R/2.
I want to impose an 'imaginary' grid. Such that I can collect the number of each of these points falling within a specific grid location. The actual 'grid' size is variable.
Should I try and collate this data from my C++ program and then post-process it in some other s/w like matlab?

Okay so i have everything right accept transfering the selectedindex from listbox in form1 to listbox in form2. I am using the below string item to hold the selected line of the list box, with the intent of recalling and then adding it into the form2 listbox. I get a not implemented error and i can't figure out why. I know the information is moving with the variable item, it just doesn't get printed out to the new listbox.
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
string item = listBox1.SelectedItem.ToString();
Form2 form2 = new Form2();
form2.Show(item.ToString());

I have a program I have been working on where the user selects a date and enters the number of days to be viewed in the Calendar.cshtml view. This input renders another view (Update.cshtml) that contains two date picker boxes, one that should contain the selected date and the second one that should contain the calculated date. I am having an issue getting the date selected in the first view to populate to the first date block on the second view as the default and getting the calculated date to populate the second date block in the Update.cshtml view. In addition given the two dates, I would like to generate a calendar, which is why I chose the date picker approach and setting static dates.
Here is my code:
**CalendarController:**
using System.Web.Mvc;
using VanickCalendarApp.Models;
using System;
namespace VanickCalendarApp.Controllers {
public class CalendarController : Controller {

I have loop that want to call abee1 , abee2 one each time and copy myarray into it . It means that I reach the name of abee1 to abee2 in the loop for doing this. I made the name of each one by using strings ( abee1 , abee2) in the loop. In the last I want to copy the myarray into the abee1/2 using pointer.

I have a working lab project with a loop error. Code posted in second post. Here's the requirements:
*
- program has to be able to handle file failure
- must loop (prefer to use a while loop here), read in the data, calculates values, etc. and then output the results.
*
The input data file includes
1. a 1 or a 0 indicating that there is a set of employee data following
2. the hourly rate of the employee
3. the humber of hours worked
4. the number of dependents
5. a 1 or a 0 indicating whether the employee is full time (1=full time).
Problem: At first I wouldn't loop back... so I moved the curly brace above the return0;
