I have 2 buttons on my Form.
My question is if button1 can activate button2 in any way.
Is it possible to write any code inside button1 that will execute/activate the code inside button2 ?

Short answer: yes — a button can cause another button’s action to run, but the best approach depends on whether the goal is to "simulate a user click", "reuse the same logic" or simply "enable/activate" the other control.

’s refactor advice is the most robust: move shared work out of the Click handler into a purpose-named method or (better) into a non-UI class so both handlers call the same routine. That makes the behavior testable and avoids duplicating logic or tightly coupling UI handlers to each other.

To simulate a user click (so all Click subscribers run), WinForms provides a built-in method:

// triggers Click as if the user clicked the button
button2->PerformClick();

If the intent is simply to make the other button usable, change its properties:

button2->Enabled = true;
button2->Visible = true;
button2->Focus();   // or Select()

Cautions and edge cases: calling a handler method directly executes only that method (it won’t raise the Click event to other subscribers), so it’s less faithful than PerformClick. Also, UI controls must be touched on the UI thread — from a background thread use Invoke/BeginInvoke (or a helper method that checks InvokeRequired) before calling PerformClick or changing properties.

Summary: prefer extracting business logic out of event handlers; use PerformClick only when simulating a real click is desired; and always be mindful of threading and side effects when one control triggers another.

If the code is run from more than one event, you should refactor it into a method:

void button1_Click(Object^ sender, EventArgs^ e)
{
  // Stuff for button 1

  Button2Stuff();
}

void button2_Click(Object^ sender, EventArgs^ e)
{
  Button2Stuff();
}

void Button2Stuff()
{
  // Stuff for button 2
}

You can also fire an event handler directly since it's just another method:

void button1_Click(Object^ sender, EventArgs^ e)
{
  // Stuff for button 1

  button2_Click(this, EventArgs::Empty);
}

void button2_Click(Object^ sender, EventArgs^ e)
{
  // Stuff for button 2
}
