Can a timer be started as a thread and execute with KeyDown?

When I press the Up arrow key, a picturebox1 has to go up and down the form vertically (jumping). At the same time, I would like the timer tick event to continue to move another picturebox2 from right to left on the form by 1 pixel for each tick event.

Initially, these 2 events cant be dealt with concurrently by vb, so I used the Application.DoEvent() method recommended by some replies I have received in the forums.

It works partially. Pictuerbox2 can move while the up arrow key is being pressed but it moves jerkily. Besides, when the arrow key is being released, picturebox1 continues to jump when it is supposed to stop.

So can I start a new thread which can execute when these 2 events occur?
If so, could you provide a simple example?

Hi,

You can use the KeyDown event and execute then your code;
VB Code:
Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
        
        If e.KeyCode = Keys.Up Then
            ' execute here your code to change the location of your TextBox
      else
          Timer1.Enable = False                      
          End If
        
    End Sub
Hope it helps,
