Preventing Document Modification in Windows SharePoint

Windows SharePoint Services 3.0 provides a versioning capability that prevents documents from being overwritten by creating a version of the file each time a change is made to either the file or the metadata. However, there may be specific situations, such as archival or records-management scenarios, in which you want to let users modify metadata but not modify the file contents; that is, there is always only one version of the file. This Microsoft Office Visual How To shows how you can enable this in specific scenarios by using event handlers and handling short-term and long-term check-outs.
