In my MainWindow I have a UserControl called CamAccessLevel1. This will be one of a few different UserControls which will have more and more functionality to a device as the Level goes up.
Each of those functionalities are themselves a UserControl, so that I don't have to keep remaking them for each different "Level" that I make.
So... I have a UserControl in a UserControl in my Mainwindow. My first goal is to have a button in one of those sections send an event back to the MainWindow to close the application. This sections is called "ProgramControl", as it has functions that relate to the program itself.
I can't seem to set a datacontext within another datacontext -> There is an error in UIViewModel below...
Note that I have replaced my company name with [snip]
In my Mainwindow.xaml
<views:CamAccessLevel1 x:Name="UserInterface"/>
Mainwindow.xaml.cs
public partial class MainWindow : Window {
#region MyModel

I have a submit button, where users are clicking after entering text into textboxes and (hopefully) check boxes (for yes/no).
Here is my code, and when I run it and press submit, there is no action. It just continues to loo.
string ConnectionString = @"Data Source=.SQLEXPRESS;
AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True";
using (SqlConnection dataConnection = new SqlConnection(ConnectionString)) {
using (SqlCommand dataCommand = dataConnection.CreateCommand())
[Code] .....
Note: I took out the Checkboxes in the code to hopefully get a successful run, to no avail.

I want to set the rootpath of an executable application. This rootpath should be the same as the path of an item that I select from a ListBox. The code for selecting the item is as follows.
namespace Menu {
public partial class Form1 : Form {
private Button button;
private ListBox listBox1;
private string selecteditem;
[Code] ....
Now what I want is: Whatever I get the output as in the :
Console.Writeline(path + selecteditem),
I would want to set this as a rootpath for an application so as to do rest of the measurements or steps only in that path/folder. Is it possible to do something like this?

I am trying to get my service to install into services but it will not. When I go to the command line and run the InstallUtil.exe service.exe it fails miserably. This is what I get on my console:
The Install phase completed successfully, and the Commit phase is beginning.
See the contents of the log file for the C:publish codeImportImport. exe assembly's progress.
The file is located at C:publish codeImportImport.InstallLog.

No public installers with the RunInstallerAttribute.Yes attribute could be found in the C: publish codeImportImport.exe assembly.
Remove InstallState file because there are no installers.

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 am trying this without a head/start pointer which would generally hold the address of first node. I have 3 nodes here from which I am trying to delete last node, but its not happening. I might be wrong in my logic and this is my first linked list program.
#include <stdio.h>
#include <stdlib.h>
struct dll{
struct dll *prev;
int data;
struct dll *next;
[Code] ....
output::::
add of p1::0x9605008 add of p2::0x9605018 add of p3::0x9605028 add of p1->prev::(nil) add of p1->next::0x9605018 add of p2->prev::0x9605008 add of p2->next::0x9605028 add of p3->prev::0x9605018 add of p3->next::(nil)
no of nodes 3
enter the addresss of node to delete it
0x9605028
after deletion attempted
add of p1::0x9605028 add of p2::0x9605018 add of p3::0x9605028 add of p1->prev::0x9605018 add of p1->next::(nil) add of p2->prev::0x9605008 add of p2->next::0x9605028 add of p3->prev::0x9605018 add of p3->next::(nil)
no of nodes 3
In this example i am trying to delete the node 3 which is p3, by deleting its address 0x9605028. But after deletion the node count is still 3 and addresses are like unexpected!

So everything works perfectly, well not everything lol. Code compiles successfully without any errors but previous day does not calculate. In a sense that when it asks for number of previous days it returns a blank statement.
For example: Previous number day is: shows nothing

So I'm making my first program w/ C++ and its a game guessing game. I've learned how to use booleans, chars, strings, if/else, loops, and input. Anything past that I dont know. I've gotten my game to work properly except for the fact that when you guess incorrectly, the program closes. I want the program to go to the beginning of the program again so the user can restart. So far i've gotten the loop to beginning thing to work but not well. It'll only repeat twice before closing again and it'll say the user got the wrong answer even if it was correct. Here's my code
#include <iostream>
#include <string>
#include <random>
#include<ctime>
using namespace std;
int game(){
string playerName;
int guess;

I am need to compare 2 items from 2 separate drop down lists. These values are of int type. Say for example 2 drop down lists showing years. Now i need to find out these 2 years selected is greater or nearer to the current year.
I tried converting the values i receive from the drop down lists to int variables. But i am getting error then. I gave it like below.
int tmp = Convert.ToInt32(ddl_1.SelectedItem.Text);
this gives an error like this - Input string was not in correct format.
I need to know how to put an item from a drop down list to a variable of int data type.

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 grabbing data from three entities and want to grab a field value in each of the entites and place it in an arraylist. What I would like to do is loop through the arraylist for all the values and do something for each value only once. If the value in the array list is repeated, I want to not do anything for it and continue till the end. Basically, I loop through all the values do something for each value and skip over the repeated value if I already did something.
