Interval of 1 Second:

Thread.Sleep(1000);

To an unfocused window:

Import and use PostMessage/SendMessage API.

Here it goes:

Code:
public const Int32 VK_RCONTROL = 0xA3;
public const Int32 VK_LEFT = 0x25;
public const Int32 VK_UP = 0x26;
public const Int32 VK_RIGHT = 0x27;
public const Int32 VK_DOWN = 0x28;


if (checkBox7.Checked == true)
            {
                SendMessage(this.Handle, VK_RCONTROL, VK_LEFT, 0);
                SendMessage(this.Handle, VK_RCONTROL, VK_UP, 0);
                SendMessage(this.Handle, VK_RCONTROL, VK_RIGHT, 0);
                SendMessage(this.Handle, VK_RCONTROL, VK_DOWN, 0);
                Thread.Sleep(1000);
            }


Code:

You want to send WM_KEYDOWN.

And how did you define your import for SendMessage (I recommend PostMessage cause you don't really need the return).

Code:
//C# Signature for the SendMessage() API
        [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
        static extern IntPtr SendMessage(IntPtr hWnd, Int32 Msg, IntPtr wParam, IntPtr lParam);


So what should i do if i want to send CTRL + Left Arrow?

the error says that you can't set IntPtr as const try replace them with int
then at the import line switch wParam & lParam to long / int whatever i guess it could be it

I did

Code:


        public const int VK_RCONTROL = 0xA3;
        public const int VK_LEFT = 0x25;
        public const int VK_UP = 0x26;
        public const int VK_RIGHT = 0x27;
        public const int VK_DOWN = 0x28;

        [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
        static extern IntPtr SendMessage(IntPtr hWnd, Int32 Msg, long wParam, int lParam);


And the result is:

Code:
(292,17): error CS1502: The best overloaded method match for 'tibian.Form1.SendMessage(System.IntPtr, int, long, int)' has some invalid arguments
(292,64): error CS1503: Argument '4': cannot convert from 'System.IntPtr' to 'int'

^ You are passing an IntPtr as the 4th argument.. but the function is expecting an int, update the definition.

SendMessage() will not return until the message has been processed, consider using PostMessage(). Instead of defining the virtual key codes for each key, try using the System.Windows.Forms.Keys enum.

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

const uint WM_KEYDOWN = 0x100;

Code:
PostMessage(hWnd, WM_KEYDOWN, (int)Keys.A, 0);

Code:
PostMessage(hWnd, WM_KEYDOWN, (int)Keys.A, 0);

Was great!

But the thing i dont get is: How do i tell it to hold down CTRL while pressing a key?

I searched on Msdn but couldn't fint out how to do that.

You can try fiddling with AttachThreadInput & SetKeyboardState. I've created an example below that will send Ctrl+F to Notepad (note: the find dialogue won't open if there is no text),

Code:
[DllImport("user32.dll")]
static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);

[DllImport("kernel32.dll")]
static extern uint GetCurrentThreadId();

[DllImport("user32.dll")]
static extern uint GetWindowThreadProcessId(IntPtr hWnd, IntPtr lpdwProcessId);

[DllImport("user32.dll")]
static extern bool AttachThreadInput(uint idAttach, uint idAttachTo, bool fAttach);

[DllImport("user32.dll")]
static extern bool GetKeyboardState(byte[] lpKeyState);

[DllImport("user32.dll")]
static extern bool SetKeyboardState(byte[] lpKeyState);

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

const uint WM_KEYDOWN = 0x100;

Code:
public void SendCTRLxKey() // Ctrl+F to Notepad
{
    Process[] processes = Process.GetProcessesByName("notepad");

    if (processes.Length > 0)
    {
        IntPtr hWnd = FindWindowEx(processes[0].MainWindowHandle, IntPtr.Zero, "Edit", null);

        uint curThreadId = GetCurrentThreadId();
        uint winThreadId = GetWindowThreadProcessId(hWnd, IntPtr.Zero);

        AttachThreadInput(curThreadId, winThreadId, true);
        this.Focus();

        byte[] kbState = new byte[256];
        GetKeyboardState(kbState);

        kbState[(int)Keys.ControlKey] |= 0x80;
        SetKeyboardState(kbState);

        PostMessage(hWnd, WM_KEYDOWN, (int)Keys.F, 0);
        Thread.Sleep(20);

        kbState[(int)Keys.ControlKey] &= 0x00;
        SetKeyboardState(kbState);

        AttachThreadInput(curThreadId, winThreadId, false);
    }
}

Results might vary from window to window. I've only sent the key down message for F, you may wish to add the key up and Ctrl key down/up messages also.

Here's how I did it.

make a timer.

Set the timer interval in the properties.

In the form
Code:
Timer1.Enabled = true;


In the timer code
Code:
SendKeys.Send("Hello World!");


OR in the timer you could put....


Code:
SendKeys.Send ("({enter})");


Or any other key...
