Library to send mouse and key Inputs

I have a project where i need to send Mouse and Key Inputs on a Global level from my WindowsForms application.
I need somethig like https://www.nuget.org/packages/H.InputSimulator#readme-tab, the only problem ive got with this library is that once i send the key i cant get it to be held down, a crucial point of the project is that i need to simulate the held down key for a small amount of time (for example if i hold the key down for 2 seconds i get: lllllllllllllllllllllllllllllll). Does anyone know a library that is able to do that or know a way to do that with the given library?

i cant get the key to be held down, do you know what i have done wrong?

InputSimulator inputSimulator = new InputSimulator();

private void button1_Click(object sender, EventArgs e)
{
    this.ActiveControl = textBox1;

    inputSimulator.Keyboard.Sleep(2000)
        .KeyDown(VirtualKeyCode.VK_D)
        .Sleep(2000)
        .KeyUp(VirtualKeyCode.VK_D);

    MessageBox.Show("Done");
}

InputSimulator inputSimulator = new InputSimulator();

private void button1_Click(object sender, EventArgs e)
{
    this.ActiveControl = textBox1;

    inputSimulator.Keyboard.Sleep(2000)
        .KeyDown(VirtualKeyCode.VK_D)
        .Sleep(2000)
        .KeyUp(VirtualKeyCode.VK_D);

    MessageBox.Show("Done");
}

Try to use async method and call KeyDown then await Task.Delay(2000) and then KeyUp

RohesKätzchenOP•2/14/24, 7:43 PM

 private async void HoldDown()
 {
     this.ActiveControl = textBox1;

     inputSimulator.Keyboard.Sleep(2000).KeyDown(VirtualKeyCode.VK_D);
     await Task.Delay(2000);
     inputSimulator.Keyboard.KeyUp(VirtualKeyCode.VK_D);
 }

 private async void HoldDown()
 {
     this.ActiveControl = textBox1;

     inputSimulator.Keyboard.Sleep(2000).KeyDown(VirtualKeyCode.VK_D);
     await Task.Delay(2000);
     inputSimulator.Keyboard.KeyUp(VirtualKeyCode.VK_D);
 }

i tried doing it like this but this also doesnt work

i just noticed that whenn i try it in a game for example minecraft the key actually gets held down so i can walk, but when i try it in a text Programm it only gets a single input

InputSimulator inputSimulator = new InputSimulator(); private void button1_Click(object sender, EventArgs e) { this.ActiveControl = textBox1; inputSimulator.Keyboard.Sleep(2000) .KeyDown(VirtualKeyCode.VK_D) .Sleep(2000) .KeyUp(VirtualKeyCode.VK_D); MessageBox.Show("Done"); }

private async void HoldDown() { this.ActiveControl = textBox1; inputSimulator.Keyboard.Sleep(2000).KeyDown(VirtualKeyCode.VK_D); await Task.Delay(2000); inputSimulator.Keyboard.KeyUp(VirtualKeyCode.VK_D); }
