There is NuGet Package called PropertyChanged.Fody It mange all that

https://github.com/Fody/PropertyChanged

That's why Main Navigation work

I'm sorry about that. Uploaded

ViewModels are in it own project and it is in the project

HoursTrans.ViewMoudels

thnx a lot volatile field works fine

Um. i manged the code i didn't type every thing. there is a method that add the list when the form load I'm sure that at less there is 5 object in the list before i click the button.

the problem is not at list objects the problem is after is start any one of states (ex. DataWorkState.RunWork,...) ican't change it again even if i Suspend the thread and resume it. like the thread is looked in the first state it start with

i find way to do it

const uint WM_KEYDOWN = 0x100;
const uint WM_KEYUP = 0x101;
const int KeyDown = 0x0001;
const int KeyUp = 0x0002;
const byte VK_SPACE = 0x20;
const byte SpaceSC = 39;



private void button1_Click(object sender, EventArgs e)
{
Process p = (Process)comboBox1.SelectedItem;
keybd_event(VK_SPACE, 0, Key_Down , 0);
Thread.Sleep(50);
PostMessage(p.MainWindowHandle, WM_KEYDOWN, (IntPtr)Keys.D1, IntPtr.Zero);
PostMessage(p.MainWindowHandle, WM_KEYUP, (IntPtr)Keys.D1, IntPtr.Zero);
keybd_event(VK_SPACE, 0, Key_Up, 0);
}

but the code keep repeat the key pressing without stop

how to fix this

i use debugger in the first it show nothing just as normal method start and finished
no repeat or something

my last did is that

using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Threading;
using System.Windows.Forms;

namespace KeysWithModefier
{
    public class Class2
    {
        private Process _p;

        [DllImport("user32.dll", SetLastError = true)]
        static extern void keybd_event(byte bVk, byte bScan, uint dwFlags, int dwExtraInfo);

        [DllImport("user32.dll")]
        public static extern IntPtr PostMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

        const uint WM_KEYDOWN = 0x100;
        const uint WM_KEYUP = 0x101;
        const uint Key_Down = 0x0001;
        const uint Key_Up = 0x0002;

        public Class2(Process p)
        {
            _p = p;
        }

        public void SendKeyWithModefir(Keys ModKey, Keys PressKey)
        {
            keybd_event((byte)ModKey, 0, 0, 0);
            Thread.Sleep(50); ;
            PostMessage(_p.MainWindowHandle, WM_KEYDOWN, (IntPtr)(PressKey), (IntPtr)(0));
            PostMessage(_p.MainWindowHandle, WM_KEYUP, (IntPtr)(PressKey), (IntPtr)(0));
            keybd_event((byte)ModKey, 0, Key_Up, 0);
        }

        ~Class2()
        {
            GC.Collect();
        }
    }
}

                catch { }
            }
        }
    }
}

but it also same the keys keep pressing tell i close the app i ideas how to make this class like app closed with out close it?

when i remove the line :

keybd_event(VK_SPACE, 0, Key_Up, 0);

the app stop repeat the code put the space didn't release i didn't now why

i try to use third part dll inputsimulator & inputsimulator plus

InputSimulator sss = new InputSimulator();
Process p = (Process)comboBox1.SelectedItem;            sss.Keyboard.KeyDown(VirtualKeyCode.SPACE);            Thread.Sleep(50);            PostMessage(p.MainWindowHandle, WM_KEYDOWN, (IntPtr)Keys.D1, IntPtr.Zero);            PostMessage(p.MainWindowHandle, WM_KEYUP, (IntPtr)Keys.D1, IntPtr.Zero);            sss.Keyboard.KeyUp(VirtualKeyCode.SPACE);

same error keep repeat the pressing

const uint Key_Down = 0x0001;
const uint Key_Up = 0x0002;
const byte VK_SPACE = 0x20;
const byte SpaceSC = 39;




private void button1_Click(object sender, EventArgs e)
{

i try all that and more but same error and msdn say the the key down value is
KEYEVENTF_EXTENDEDKEY
0x0001
as my Key_Down i didn't get the error in my code why it keep repeat all the pressing

const uint WM_KEYDOWN = 0x100;
const uint WM_KEYUP = 0x101;
const int KeyDown = 0x0001;
const int KeyUp = 0x0002;
const byte VK_SPACE = 0x20;
const byte SpaceSC = 39;


private void button1_Click(object sender, EventArgs e)
{
Process p = (Process)comboBox1.SelectedItem;
keybd_event(VK_SPACE, SpaceSC, KeyDown, 0);
Thread.Sleep(50);
PostMessage(p.MainWindowHandle, WM_KEYDOWN, (IntPtr)Keys.D1, IntPtr.Zero);
PostMessage(p.MainWindowHandle, WM_KEYUP, (IntPtr)Keys.D1, IntPtr.Zero);
keybd_event(VK_SPACE, SpaceSC, KeyUp, 0);
}

code u please point to the wrong values in this code because it keep repeat the keys

if u mean {Note This function has been superseded. Use SendInput instead.}

i try SendInput and the same error the application keep repeat the keys

i try to create key presser for game

one of game commands is (Space + number)

i try to simulate this with code

but when i do that the result with code is just as i press the number only not as i press (Space + number)

yes but it didn't do the effect as when i press them manual

i try it but not work i need it to press (Space + 1)

i add it and the same error
