What does the SPWeb.ParserEnabled property do?

nishandv — Sat, 07 Jun 2008 01:57:31 GMT

When we set SPWeb.ParserEnabled to false, it disables the document parser (there will not be any property demotion and promotion), it means that the file properties and the WSS properties will not be in sync. So when you search for a custom file property value, the search result won't return you the file.

How to hide subsite's GlobalNavigation nodes/tabs through SharePoint API?

nishandv — Tue, 11 Sep 2007 01:29:48 GMT

When we create a site either through UI or OM, it will not come as a tab unless you check the option ‘Site Actions-->Site Setting-->Navigation-->Show subsites to true’.

On checking the option results in displaying all the subsites as ‘Tabs’. If you want to hide some of them programmatically, you need to change the ‘__GlobalNavigationExcludes’ property from the property bag of SPWeb object.

Consider I have a site with 10 subsites, I enabled the option Site Actions--> Site Settings-->Navigation--> Show subsites to 'true, I can see now 10 addtional tabs, If I say SPWeb.Navigation.GlobalNodes.Count wont return a value approx equal to 10.

SPSite site = new SPSite("http://nishandv3:100/Sites/DevSite/");

SPWeb web = site.OpenWeb();

string strGlobalNavigationExcludes = web.AllProperties["__GlobalNavigationExcludes"].ToString();

web.AllProperties["__GlobalNavigationExcludes"] = strGlobalNavigationExcludes + "{569F3E30-F9AF-44d5-A52C-47670FC3FEAC}";

// 569F3E30-F9AF-44d5-A52C-47670FC3FEAC" is the GUID of the web you want to hide from the navigation.

web.Update();

Hope this helps!

How to update Content Types through the Object Model?

nishandv — Mon, 21 May 2007 02:34:39 GMT

When we add a field to the site content type SharePoint doesn't push-down those changes to the document library and the list level. The below code sample is for push-down all the changes to document libarary and the list level.The sample code from WSS 3.0 SDK doesn't seem to be working :)

SPField field = spWeb.Fields[“YourNewField”]; //you can pick one from the site column collection for create a new one.

SPFieldLink fieldLink = new SPFieldLink(field);

SPContentType contentType = spWeb.ContentTypes[“Site Level Content Type”];

contentType.FieldLinks.Add(fieldLink);

contentType.Update(true);

How to create an XMLFormView control in custom aspx page within SharePoint?

nishandv — Mon, 21 May 2007 00:44:09 GMT

Adding “XmlFormView” control to a custom aspx page that provisioned within SharePoint throws an exception “Session state cannot be enabled here.”

XmlFormView control requires session state to be enabled.

To enable the session, open the web application’s web.config file,

1. Under <httpmodules> enable the session module
<add name="Session" type="System.Web.SessionState.SessionStateModule"/>
2. Set the <page> tag attribute enableSessionState="true"
3. Add a Safe control entry for the XmlFormView control
<SafeControl Assembly="Microsoft.Office.InfoPath.Server, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" Namespace="Microsoft.Office.InfoPath.Server.Controls" TypeName="*" Safe="True" />

4. In aspx page the control tag looks like :- <cc1:XmlFormView ID="XmlFormView1" XsnLocation="~sitecollection/FormServerTemplates/Userfeedback.xsn" runat="server" Height="250px" Width="100%"/>

Note: If you are gonna write some code within your custom aspx page then you need to write add the node <PageParserPath> in your web.config file of your web application

UserProfileManager object creating fails when we try to create an instance from a SharePoint workflow application.

nishandv — Mon, 21 May 2007 00:18:16 GMT

A work-around to this issue is, execute the code under admin privileges(impersonate the user), you can either follow the Win API impersonation or using the SPSecurity.RunWithElevatedPrivilages() method.

You would get errors like,

'Microsoft.SharePoint.SPException'
base {System.ApplicationException}: {"Cannot complete this action.\n\nPlease try again."}
ErrorCode: -2147467259
UserProfileChangeJobSchedule: 'new UserProfileManager(context,false).UserProfileChangeJobSchedule' threw an exception of type 'Microsoft.SharePoint.SPException'

SPSecurity.RunWithElevatedPrivilages(delegate()

{

ServerContext context = ServerContext.GetContext("SharedServices2");

UserProfileManager manager = new UserProfileManager(context);

});

"User cannot be found." error when creating an FBA site programmatically through Windows application or a console application.

nishandv — Mon, 21 May 2007 00:04:19 GMT

When we create an FBA site through console app or a windows app, we need to have the membership provider and the role provider information within App.Config file. It would be with the same structure as we have in the web.config file of SharePoint WebApplication.

App.Config for your Windows/Console application should be like this.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<sectionGroup name="SharePoint">
<section name="PeoplePickerWildcards" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
</sectionGroup>
</configSections>

Debugging Workflows

nishandv — Sat, 19 May 2007 00:07:00 GMT

It would be very painful to debugg the workflow, VS provides help to some extend, however for details log information you have to change the web.config for your web application in which the workflow is running under.

Open your web.config,

Add the below nodes,

...................................

<system.diagnostics>
<switches>
<add name="System.Workflow LogToFile" value="1" />
<add name="System.Workflow.Runtime" value="All" />
<add name="System.Workflow.Runtime.Hosting" value="All" />
<add name="System.Workflow.Runtime.Tracking" value="All" />
<add name="System.Workflow.Activities" value="All" />
<add name="System.Workflow.Activities.Rules" value="All" />
</switches>
</system.diagnostics>
</configuration>

The log file created under C:\WINNT\system32\inetsrv
