.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()
