.NET ToolTip control doesn't expose Handle property. 
Then we should use InvokeMember to retrieve that property

The following function returns the handle:

 Public Shared Function GetToolTipHandle(ByVal ctrlToolTip As ToolTip) As IntPtr
 
        Dim obj As Object
        Dim hwnd As IntPtr
        Try
            hwnd = IntPtr.Zero
            obj = GetType(ToolTip).InvokeMember("Handle", Reflection.BindingFlags.NonPublic Or Reflection.BindingFlags.Instance Or Reflection.BindingFlags.GetProperty, Nothing, ctrlToolTip, Nothing)
            hwnd = CType(obj, IntPtr)
        Catch ex As Exception
 
        End Try
        Return hwnd
 
 End Function

How to use the function in your program:

 Dim hwnd as IntPtr = GetToolTipHandle(ToolTip1)

To convert the pointer to numeric(integer) use like this:

 hwnd.toInt32()
