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).

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;

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 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.
private void frmProject6_Load(object sender, EventArgs e) {
// 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 have a listbox that retrieves a bunch of values. I'm able to selectAll, Select None and Select Individual items. I'm not able to search the ListBox and select based on String value.
I have tried creating a for and if loop, but it will only select a single item (first item) in my ListBox.
private void btnSelectCAD_Click(object sender, EventArgs e) {
// Find CAD Line Patterns that Begin with IMPORT:
string mySearchString = "IMPORT";
// Search Listbox starting from index -1:
int index = lstLinePatterns.FindString(mySearchString, -1);

I have created a Server that can handle multiple users with the select function. The server seems to be operating just fine on every new request of a client even on the case of termination connection. The problem appears on the client side. I am applying forking process to be able to hear and write at the same time while the user is typing a message to the rest of the clients. By doing so I discovered that when the client is initialized it send a blank message to the server. The server then send this blank message to all the clients. I have discovered a "trick" not to display the message on the client side but I really would like to know if there is an alternative solution instead of my solution. I mean why it dose not wait for the client to first start typing a message before to send it.
The communication that will apply on each new connection is:
Client Server
Connect() −− >
< −− Hello version
NICK nick −− >
< −− OK/ERROR text
MSG text −− >
< −− MSG nick text/ERROR text
Sample of the Server.c code:
#include <stdio.h> /* stderr, stdout */
#include <errno.h> /* errno.h - system error numbers */
#include <stdlib.h> /* memory allocation, process control etc. */

I want to display the content of my database in list view. The table has 5 columns however when I tried this code
string view = "Select * from cust_infor";
SqlCommand cmd = new SqlCommand(view,FL.clsconnection.opencon());
SqlDataReader dr = cmd.ExecuteReader();
listView1.Items.Clear();
while (dr.Read()) {
listView1.Items.Add(dr[0].ToString()).SubItems.Add(dr[1].ToString());
}
It limits the display to 2 columns. List view will only show the first 2 columns. The code above won't let me add more indexes or subitems. Only up to 2 columns.

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.

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 {

So I've got a button that has to use 2 textboxes to search for 2 columns in my database.
private void btnFilter_Click(object sender, EventArgs e) {
SQLiteDataAdapter adap = new SQLiteDataAdapter("select * from Test", GetConnection());
DataSet ds = new DataSet();
adap.Fill(ds);
dgvTable.DataSource = ds.Tables[0];
[Code] ....
My Current code for it.
The GetConnection(); and the CloseConnection(); Methods are just making a new connection and closing that connection, if needed I can post that code too later.
But basically, It only "filters" 1 textbox but if I say I want to search the Channel and the Log in which it is in, it doesn't search anything and returns all data in the database.

So I have an application that needs to send the current IP Address to a service. My problem is that I have a couple of machines that show two IPV4 addresses on the same NIC. Unfortunately the standard .net calls for the IP Address always appear to show the IP Addresses in numerically sorted order and it will be random as to which one of multiple IP Addresses my application uses.
Any way to force Windows 7 and XP to always put a specific IP address as the first one regardless of the numerical order?

I have a tcp client - server implementation running in the same program, on different background worker threads. There will be instances of this program on multiple computers so they can send and receive files between each other. I can send files sequentially between computers using network stream, but how would I send multiple files at the same time from computer A to B.
Sending multiple files over one connection ( socket ) is fine, but having multiple network streams sending data to a client, the client doesn't know which chunk of data is apart of which file ?

I'm having a bit of trouble with something. What I'm trying to do is create a new Access table by combining other already existing Tables.
For instance, let's consider Table1 (with columns A, B and C), Table2 (with columns A, D and E) and Table3 (with columns A, F and G), where Table1.A = Table2.A = Table3.A.
From these, I want to create a new table TableResult, with columns A, B, C, D, E, F and G, with all the data contained in them. There's one catch: I want the code to get the names of the other columns, apart from column A.
I've thought about using Union, but I need to actually create a new table by combining the previous tables.

222 | Nicole
333 | John
Now, I want all that under column Id which is 111, 222 and 333 will be save on my database once I click Save button I am trying the code below but it gives me an error saying "system.data.sqlclient.sqlparameter does not contain a definition for 'Values' and no extension method 'Values' accepting a first argument of type..." :
SqlConnection con = new SqlConnection("Data Source=GATE-PCSQLEXPRESS;Initial Catalog=dbProfile;Integrated Security=True");
SqlCommand cmdd = new SqlCommand("Insert into profile (Id, profile_id)VALUES(@id, @profile_id", con);
foreach (GridViewRow row in GridView1.Rows) {

I have the following code which allows me to add the pdf files if I give the exact name and path of the file. But I have multiple pdf files in a folder which I want to add to each cell in the first column. I am having trouble thinking of the logic to have a for loop for a folder which contains the pdf files.
private void button1_Click(object sender, EventArgs e) {
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
xlApp = new Excel.ApplicationClass();
xlWorkBook = xlApp.Workbooks.Add(true);
[Code] ...
But this is very very rough draft. I have say 20 files in the folder pdf with different names(Title). How can I add all the 20 pdf files in the excel sheet?

I have an EDI file whose structure is given below. This file has multiple records, each record contains a header (e.g EDI.DD.0000000001.20130809), then contents (i.e multiple paragraphs of text) and then footer (e.g End of Report/No EDI Activity). I have to read that entire file using regular expression using three groups.
I am using following regular expression to read the file.
(?<header>[A-Z]{3}.[A-Z]{2}.[0-9]{10}.[0-9]{8}) | (?<footer> (EndsofsReport|NosEDIsActivity)) |
(?<content>(?<=k<header>).*(?=k<footer>))
That expression reads the "header" and "footer" in respective groups properly but didn't pick the contents between header and footer in "contents" group.
I have changed the font of header and footer in below file to understand the format. I am using asp.net 3.5 framework.
