How can I send key in Delphi

To send a key press in Delphi, you can use the Windows API function SendInput. SendInput allows you to simulate input events, including key press and release events, in the operating system.

Here is an example of how you can use SendInput to send a key press in Delphi:

uses
  Windows;

procedure SendKeyPress(Key: Word);
var
  Inputs: array[0..0] of TInput;
begin
  Inputs[0].Itype := INPUT_KEYBOARD;
  Inputs[0].ki.wVk := Key;
  Inputs[0].ki.dwFlags := 0;
  SendInput(1, Inputs[0], SizeOf(Inputs[0]));
end;

uses

Windows;

procedure SendKeyPress(Key: Word);

var

Inputs: array[0..0] of TInput;

begin

Inputs[0].Itype := INPUT_KEYBOARD;

Inputs[0].ki.wVk := Key;

Inputs[0].ki.dwFlags := 0;

SendInput(1, Inputs[0], SizeOf(Inputs[0]));

end;

This function takes a key code as an argument and sends a key press event for that key. To send a key release event, you can set the dwFlags field of the TInput.ki record to KEYEVENTF_KEYUP.

To use this function, you can call it with the key code of the key that you want to send. For example, to send the A key, you can call SendKeyPress(VK_A).
