Clear Cache within module event handler

How could I clear the cache in my module's event handler? I know the core does this in one and only one place in the whole application:
Taken from HostSettings.ascx.vb
        Public Sub cmdCache_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdCache.Click

            ' clear entire cache
            DataCache.ClearHostCache(True)

            Response.Redirect(Request.RawUrl, True)

        End Sub

When I try to insert DataCache.ClearHostCache(True) in my module's update event handler, the error appears:
'ClearHostCache' is not a member of 'DotNetNuke.UI.Utilities.DataCache'.
How can I call this function from within my module? I tried to import all namespaces that were imported in HostSettings.ascs.vb but the error remains. These include:

DotNetNuke.Common.Utilities.DataCache

DotNetNuke.UI.Utilities.DataCache

I need to clear the cache because I am dynamically altering tables in my database manually. By doing so, the updates bypass the web application and will only be reflected once the cache is cleared. I want to clear the cache from within the event handler to avoid having the user to do this through Host.Advanced Settings.Other Settings.Clear Cache.

Please Help!

Maybe it's getting confused, have you tried using the line like:-

DotNetNuke.Common.Utilities.DataCache.ClearHostCache(True)

This would make sure, you are using the correct class.

Glad to hear it, clashing class names can sometimes be a problem, the best way to know exactly what class you are calling is to right click in visual studion on the name of the class and selecting "go to definition".
