In visual studio I have a program that currently takes 5 pictures everytime you click the button. I want the program to take those 5 pictures then change the Aperture setting and take 1 last picture.
There isn't really relevant code, so this is for someone who already understands the SDK.
I've already looked around quite a bit for how to handle this, but I'm rather inexperienced with coding in general.
Thanks!
maybe useful code

I want to access the latest checkstates and the latest set date value using a function called GetProfileFilter. Now my problem is I'm not able to fetch the latest values when either the checkbox.Checkstate is changed or the datetimepicker is changed.I'm setting the values based on whether the checkboxes are set and I intend to use the IBitWise value elsewhere.Note that at form load all the checkboxes are checked.In the form class I have nothing more than a few variable and the event handlers for buttons and checkboxes and date time pickers.Open to all suggestions!!
class Profile{
public bool GetProfileFilter()
{
if (frmInactive.btnApplyWasClicked == true || frmInactive.btnCancelWasClicked == false)

I am trying to auto check every new item in my checkedboxlist I have a button that does that it will auto select all, but we don't want it that way to be controlled by a button. we want it so for every new item we get automatically will get checked.
This is my button that auto select all if there are new 20 items this will auto select all and then submit those new items
Here is the code it works but is not I want I want to auto select for every new items coming in, because I have another process that will keep adding new items to the checkedboxlist, also the lst_BarcodeScanEvents is the checkedboxlist name
private void btn_SelectALLScans_Click(object sender, EventArgs e)
{
for (var i = 0; i < lst_BarcodeScanEvents.Items.Count; i++)
{
lst_BarcodeScanEvents.SetItemChecked(i, true);
}
}
I checked other sources like google and stackoverflow but I could not find anything to my request here.
Here is the main class where I have the logic of buttons, checkedlistbox and more. and the button method btn_ConnectT_Click calls the methods from the second class

Here is the second class where I use a telnet port 23 that scan barcodes where and puts it to the checkedlistbox, now the main emethods here that inserts the data to the checkedlistbox is the method serversocket and the readwrite method
using System;
using System.Collections.Generic;
using System.Net.Sockets;
using System.Text;
using System.Threading;
using System.Windows.Forms;
namespace BarcodeReceivingApp.Functionality
{

private int _port;
private BarcodeReceivingForm _form;
private bool _isExiting = false;
public TelnetConnection(string hostname, int port)
{
this._hostname = hostname;
this._port = port;
}
public void ServerSocket(string ip, int port, BarcodeReceivingForm f)
{
this._form = f;
try
{
_client = new TcpClient(ip, port);
}
catch (SocketException)
{
MessageBox.Show(#"Failed to connect to server");
return;
}
_networkStream = _client.GetStream();
_readWriteThread = new Thread(ReadWrite);
//_readWriteThread = new Thread(() => ReadWrite(f));
_readWriteThread.Start();
}
public void Exit()
{
_isExiting = true;
}
public void ReadWrite()
{
do
{
var received = Read();
if (received == null)
break;
if (_form.lst_BarcodeScanEvents.InvokeRequired)
{
var received1 = received;
_form.lst_BarcodeScanEvents.Invoke(new MethodInvoker(delegate
{
_form.lst_BarcodeScanEvents.AddItem(received1 + Environment.NewLine);
}));
}
} while (!_isExiting);
//var material = received.Substring(10, 5);
//_form.label5.Text += string.Join(Environment.NewLine, material);
CloseConnection();
}
public List<string> GetBarcodeList()
{
var readData = new List<string>();
foreach (string list in _form.lst_BarcodeScanEvents.Items)
{
readData.Add(list);
MessageBox.Show(list);
}
return readData;
}
public string Read()
{
var data = new byte[1024];
var received = "";
var size = _networkStream.Read(data, 0, data.Length);
if (size == 0)
return null;
received = Encoding.ASCII.GetString(data, 0, size);
return received;
}
public void CloseConnection()
{
MessageBox.Show(#"Closed Connection",#"Important Message");
_networkStream.Close();
_client.Close();
}
}
}
so now like I said before for every new items it gets inserted to the checkedlistbox I want it to be auto selected everytime it adds a new data to the checkedlistbox.
The problem, usually simple, of setting the Checked state of a newly added Item of a CheckedListBox, was somewhat complicated because of the nature of the Listbox in question.
The CheckedListBox is a Custom Control with custom events and properties.
It's actually a relatively common customization (one implementation can be see in this MSDN Forum post:
Have ListBox an event when addid or removing Items?) but it might complicate the interpretation of the events.
The Custom Control, when adding a new Item to the List (from a class other than the Form that hosts the Control), raises the custom ItemAdded event
private void [CheckedListBox]_ItemAdded(object sender, ListBoxItemEventArgs e)
The Index of the Item added is referenced by the e.Index property of the custom ListBoxItemEventArgs object.
With the code provided, it can be determined that this event handler is the natural place where the Checked state of the new Item can be set:
private void lst_BarcodeScanEvents_ItemAdded(object sender, ListBoxItemEventArgs e)
{
lst_BarcodeScanEvents.SetItemChecked(e.Index, true);
}
For that I suggest to create an event that you subscribe after you InitializeComponent() of your form like so :
public Form1()
{
InitializeComponent();
lst_BarcodeScanEvents.ControlAdded += new ControlEventHandler(AddedNewSelect);
}
private void AddedNewSelect(object sender, ControlEventArgs e)
{
lst_BarcodeScanEvents.SetItemChecked(e.Control.TabIndex, true);
}
first of all i want you to know that i know that there a lot of results for this question, but i have searched far and wide still haven't come up with a solution for my problem.
i have tried to do the following:
1.constructor
2.objects
3.properties
4.delegates
but none of my implementation of them really did worked as wanted (in this "solution" i have used properties
when i press "back" on the "pop up" screen i dont in the main screen the value i choose from in the "pop up" screen
basically, it's something like, i have main screen and a "pop up"

I have a project that wants
A method that returns the current count.
A Constructor that sets the count to zero.
I have the first few down but need help with the return count to 0 and then the constructor. I need to do this by adding a counter class but I'm confused about the way to add it.
Can some one help me out?
