The annoying, "The site is not valid. The 'Pages' document library is missing" error when trying to set the DefaultPage property for a website.

The DefaultPage property points to a page in the PagesList, so the PagesList must be set to a valid document library before the DefaultPage property can be set.

Here's how to do this:


SPWeb newSite = mySite.Webs.Add(subsiteUrl, subsiteTitle, subsiteDescription, 1033, currentTemplate, true, false);
newSite.Update();
SPFile welcomePage = newSite.Folders[pagesFolder].Files[defaultPage];
PublishingWeb pubWeb = PublishingWeb.GetPublishingWeb(newSite);
pubWeb.PagesListId = newSite.Folders[pagesFolder].DocumentLibrary.ID;
pubWeb.Update();
pubWeb.DefaultPage = welcomePage;
pubWeb.Update();

Writing to Trace Log

Here’s some sample code for writing to the trace log.

using Microsoft.SharePoint.Administration;
private void WriteTraceLog(string logEntry)
{
SPDiagnosticsService diagnosticsService = SPDiagnosticsService.Local; SPDiagnosticsCategory cat = diagnosticsService.Areas["SharePoint Foundation"].Categories["Unknown"];
diagnosticsService.WriteTrace(1, cat, TraceSeverity.Medium, logEntry, cat.Name, cat.Area.Name);

}

The logfile’s here: C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\LOGS(SP creates a new logfile every 30 minutes.)

Administrators can use the LogLocation property of the SPDiagnosticsService class to specify the location of the trace log to which to write.The actual registry key that specifies the location of the trace log is called LogDir and is located at the following location:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0\WSS]

However, you should never edit this value directly.

(This usually defaults to: C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\LOGS)
