HTH

Ivo Stoykov

this.your_control_ID.ctrlClick();
 
to your control attach ctrlClick() to onClick event.

try this for moving

you cannot "how to click the mouse pointer". Click the mouse pointer means that your code is reacting to an event, i.e. mouse click. It is not necessary to do physically the click with the mouse.
You have to

  1. add an onClick event (i.e. double click on the button and VS will create one for you), then 
  2. in your code somewhere call the method (Sub) created in previous item 
for instance, if in item 1 you've clicked a button you'll get Button_Click ...
if your button ID is Button1 you could call it
Me.Button1.Button_Click(Me.Button1, new EventArgs())

HTH
Ivo Stoykov

to center it over a button
 
Windows.Forms.Cursor.Position = New System.Drawing.Point(Button1.Location.X + (button1.width /2) , Button1.Location.Y + (button1.height /2) )
 
if you need a visible move use a loop (for ... next)

You can use following windows APIs for your purpose.

GetCursorPos - Retrieves the cursor's position, in screen coordinates.

GetAsyncKeyState - determines whether a key is up or down at the time the function is called, and whether the key was pressed after a previous call to GetAsyncKeyState.

SendInput - synthesizes keystrokes, mouse motions, and button clicks.

You could do:

Public Class Form1
 
    Private Const MOUSEEVENTF_LEFTDOWN As Integer = &H2
    Private Const MOUSEEVENTF_LEFTUP As Integer = &H4
 
    Private Const MOUSEEVENTF_RIGHTDOWN As Integer = &H8
    Private Const MOUSEEVENTF_RIGHTUP As Integer = &H10
 
    Private Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Integer, _
      ByVal dx As Integer, ByVal dy As Integer, ByVal cButtons As Integer, _
      ByVal dwExtraInfo As Integer)
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ClickAt(600, 400, True, False)
    End Sub
 
    Private Sub ClickAt(ByVal x As Integer, ByVal y As Integer, ByVal LeftClick As Boolean, ByVal RestorePosition As Boolean)
        Dim pt As Point = Cursor.Position
        Cursor.Position = New Point(x, y)
        If LeftClick Then
            mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0)
            mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0)
        Else
            mouse_event(MOUSEEVENTF_RIGHTDOWN, 0, 0, 0, 0)
            mouse_event(MOUSEEVENTF_RIGHTUP, 0, 0, 0, 0)
        End If
