how to delete exe file MAINICON

Question

How can I delete the MAINICON resource entry in exe file(s)? Instead of changing the main icon of a given exe file, I want to delete the main icon, thus, it takes the default windows exe icon. I already know that this API function UpdateResource can change the MAINICON ( actually can change any resource) but how to delete resource?

Thanks,

UpdateResource can add, modify and delete a resource.

If lpData is NULL and cbData is 0, the specified resource is deleted from the file indicated by hUpdate.
