Prevent Form Activation/deactivation C#

[kvarnerexpress 0]

Is there a way to prevent the activation/deactivation of a form? I have tried intercepting the WM_ACTIVATE message but I was not able to successfully cancel it. The scenario that this is needed for is a parent form creates multiple child forms each hosting a axWebbrowser. I would like to have it so that the only way that a form can be activated is if a user clicks that form. In the case of the browser when it refreshes I do not want it to activate the form it's on unless it's already active. If I need to clarify anything or provide more information please let me know. Thanks
