Limit Version History

[camusa]

I was told that there is a registry key that can be changed to limit the amount of versions that are kept when version history is enabled on a document library in windows sharepoint services. Does anybody know which one?

TIA,

Chris

I dont know about a reg key but in the SDK there is an example where an eventhandler is created for this task:
Ms Windows SharePoint Services\Programming Tasks/Programming with the Object Model\Handeling Document Library events

This is the eventhandler mentioned there:

private int maxVersions = 5;

void IListEventSink.OnEvent(Microsoft.SharePoint.SPListEvent listEvent)
{
    /* TODO: ***** PROVIDE YOUR IMPLEMENTATION HERE ****
    Get the credentials (User_Alias, Domain, Password) that this event sink instance should run as
    and initialize the wic object by calling the CreateIdentity method*/

    WindowsImpersonationContext wic = CreateIdentity(User_Alias, Domain, Password).Impersonate();

    if ((listEvent.Type == SPListEventType.Update) ||
        (listEvent.Type == SPListEventType.CheckIn))
    {
        SPWeb site = listEvent.Site.OpenWeb();
        SPFile file = site.GetFile(listEvent.UrlAfter);
        int nDocVersions = file.Versions.Count;

        while ((maxVersions > 0) && (nDocVersions > (maxVersions - 1)))
        {
            file.Versions.Delete(0);
            nDocVersions = file.Versions.Count;
        }
    }

    wic.Undo();
}
