If you are writing your OWN module you can do something like the following - basically first we make sure there is a way to find the module if you are logged in as admin - and the page is in editmode.
In that specific case - allow the containcontrol to be visible.
Otherwise set the containercontrol to hidden.
Any code you want to run can be put in this module - it will still fire - regardless of if it gets displayed on the page.

protected void Page_Load(object sender, EventArgs e)
{
// set some variables - just to make it obvious what we are doing - could all be inline.
// basically do some test to see if the module should be visible for any reason
// usually some test for the current using being having admin rights to the page 
// and maybe if the page is in editmode

Bool isADMIN = ((PortalSettings.UserInfo != null &&PortalSettings.UserInfo.IsSuperUser) || TabPermissionController.CanAdminPage()) 

Bool isEDITMODE =  this.IsEditable;

if (isADMIN && isEDITMODE) 
{
//  this is the normal action for a page - let this happen in editmode for admins so that the module can be found
// on the page and removed or its settings edited
 ContainerControl.Visible = true;  // does not really need to be set here - just put in for explanation
}
else
{
// hide the module container and the module itself - nothing will be shown on the page
 ContainerControl.Visible = false;
}

//// do you hidden processing code here

}
