Operation is not valid due to the current state of the object by adding SPFolder or SPListItem

nstorandt — Mon, 29 Mar 2010 13:43:00 GMT

hey guys,

The error described above is one of the common errors which we get when developing with SharePoint Object model.

In my case the Error came up because of SPFolder "Update" using the "RunWithElevatePrivilege" method as below:

SPSecurity.RunWithElevatedPrivileges(delegate{
using (SPSite site = new SPSite("http://mySiteUrl"))
{
using (SPWeb web = site.OpenWeb())
{

SPFolder newFolder = web.Lists[listName].RootFolder.SubFolders.Add(folderUrl);

newFolder.Update();

web.Update();

}
}

});

To resolve this issue you must update your Item or Folder outside of the ElevatedPrivileges Construct as below:

SPSite site = null; SPWeb web = null

SPSecurity.RunWithElevatedPrivileges(delegate(){

site = new SPSite(m_SharePointSiteURL);

web = site.OpenWeb(m_SharePointWebName); });

SPFolder newFolder = web.Lists[listName].RootFolder.SubFolders.Add(folderUrl);

newFolder.Update();

web.Update();

if (web != null) web.Dispose();

if (site != null) site.Dispose();

cheers

SPList has no default URL Property

nstorandt — Fri, 09 Oct 2009 14:20:00 GMT

Hey guys,

if you working with SPList object be aware of this. If you create a List over C# you only submit a name. But if the name of the List is too long then the url will be truncated.

So you need access to a URL Property to get the right reference to the list!

There are several methods:

1. Access Url over RootFolder property

list = elevatedWeb.Lists[listname];

listUrl = list.RootFolder.Url;

2. Access Url over Forms Property

SPList list = elevatedWeb.Lists[listname];

listUrl = list.Forms["PAGETYPE.PAGE_EDITFORM"].ServerRelativeUrl

3. Write Extenstion Methods for SharePoint

Another Method is to extend the SPList object by writing Extensions Methods. This is described here, many thanks to Adam Buenz

Creating a SlideLibrary in C#

nstorandt — Thu, 20 Aug 2009 12:06:00 GMT

Hey guys,

this is just a short tip for you if you are working with SlideLibraries.

The SlideLibrary is not a ordinary List or Doc Library for MOSS. Its not included in the SPListTemplateType Enumeration. So how could we add such a list. First of all you have to know that the SlideLibrary was published as a Feature in MOSS. So we need to identify the FeatureID for this.

To do this go to the following path:

12hives\TEMPLATE\FEATURES\SlideLibrary

Open the Feature.xml and Copy the Id.

In your project add the following code:

Hey guys,

I have to write a little a tool which copies the files from one library to another. But the requirement was to copy the versions also.

MOSS Set Advanced Permission - Object Reference not set

nstorandt — Wed, 08 Jul 2009 09:16:00 GMT

Hey guys,

I had an strange behaviour in one of our customers portals.

Today the customer told me, that when he try to access the Advanced Permission Page of a Site in SharePoint he get an error:

Object reference not set to an instance of an object.   at Microsoft.SharePoint.SPSite.get_IISAllowsAnonymous()
   at Microsoft.SharePoint.ApplicationPages.UserRoles.InitPage()
   at Microsoft.SharePoint.ApplicationPages.CBaseAclPage.OnLoad(EventArgs e)
   at System.Web.UI.Control.LoadRecursive()
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

After some research I found a blog post which will describe the behaviour and how to fix it.

Many Thanks to Dan Lewis who has spent time on this error!!

There are several resolutions for this error described in the post above.

In my case the Authentication Provider of the WebApp was completly deleted.

So I have to extend the WebApp with a new Authentication Provider.

MOSS: Fields disappear when Print Previewing or Printing in Word 2007

nstorandt — Wed, 06 May 2009 08:30:00 GMT

Hey guys,

today I have a really strange issue.

A customer reported that when he opens a document (ReadOnly) from a SharePoint Doc Library and try to print it, the fields in the Word Document disappear directly after pressing printing or print preview. I try to print the same doc in Win 2003 and here it works fine, so it must be an Word 2007 issue.

After some searching I found a hotfix from MS. I Installed it on my test enviroment and after applying this hotfix the printing works as expected in Word 2007.

hope this helps someone

Adding Custom Folder ContentType Item to a Doc Library

nstorandt — Tue, 05 May 2009 10:07:00 GMT

Hey Guys,
Today I ran into an really stupid error. I have an Doc Library in a SharePoint Site, I create folders programmatically. Now I had the requirement to add MetaTags to that Library. After I added custom Columns to that Library my Code to Create a Folder in that Library won't work anymore, because the SPFolder.Item Object has been null.

After a while of searching I found this post, and the explanation why this happens!?

So how could I add a Folder to a Library with MetaTags!?
First of all create a new ContentType of Type Folder and insert all required MetaTags (see my post Create Folder with MetaTags)
After you have done this, you must change the code for creation of the Folder.

SPDocumentLibrary doclib = (SPDocumentLibrary)(m_SharePointWeb.GetListsOfType(SPBaseType.DocumentLibrary)[libraryName]);
string url = ((SPFolder)(doclib.RootFolder)).ServerRelativeUrl.ToString();
SPFolder folder = web.GetFolder(url);

web.AllowUnsafeUpdates = true;

SPListItem newItem = doclib.Items.Add(
doclib.RootFolder.ServerRelativeUrl,
SPFileSystemObjectType.Folder,
null);
newItem["Title"] = folderName;
newItem["Name"] = folderName;
newItem["ContentType"] = folderType;

newItem.Update();

doclib.RootFolder.Update();
web.Update();

MOSS Set Max Upload Size on IIS 7

nstorandt — Fri, 24 Apr 2009 14:50:00 GMT

Hey guys,

I ran through a new problem with MOSS and IIS 7.

If you configure your Max Upload Size in the Web Application Generell Settings, this has no affect for the upload size.

If you try to set this to e.g. 200 MB and then try to upload a file which has a size of e.g. 100 MB, you get a HTTP Error 404.13 - Not Found

To resolve this issue try the following:

This setting made the change for all Web Sites.

%windir%\system32\inetsrv\appcmd set config -section:requestFiltering -requestLimits.maxAllowedContentLength:1000000

or if you only want to set it for your app:

%windir%\system32\inetsrv\appcmd set config "Default Web Site/<your app>" -section:requestFiltering -requestLimits.maxAllowedContentLength:1000000

Attention: The maxAllowedContentLength unit is Byte!!!

MOSS How To: Change List/Site Template language

nstorandt — Wed, 18 Mar 2009 13:37:00 GMT

hey guys,

It's not a secret that sharepoint can't handle different language templates, so what if you have e.g. a english template which you want to use on a german system!?

Here is a workaround for you:

The first thing what you have to do is to save the template on your local computer.
Then rename the template.stp into template.cab
Extract all files of the *.cab file
In the extracted folder you will find an manifest.xml open it with an editor e.g. notepad, textpad
replace the current language id with the german one (1031) search the manifest file for the following strings
- <Language>1033</Language>
- <Locale>1033</Locale>
- 1033\STS\
- Layouts\1033\
- /_layouts/1033/

If it is an site template then you need to replace the following also
1. en-us with e.g. de-de
Save the manifest file with your changes
The next step is to create a new *.cab file with the changes you made
To do this use the CABARC.exe, you can find an download here
Open the command prompt and use the following statement:
- CABARC.EXE N "[TemplateFilePath].cab" [FolderIncludingTheManifestFile]"\\*.*\
Rename the generated *.cab file into *.stp
Upload the new template into an german enviroment
And try to create the List or Site with the new template

Hope it helps someone.

MOSS How To: Change Calendar Item appearance

nstorandt — Tue, 17 Mar 2009 10:14:00 GMT

Hey guys,

today i will show you how you can modify the calendar view to display e.g. start and end time of an event.

The default style is this:

To display also the end time of an event or meeting you have to create at first a new column of type calculated (calculation based on other columns).

Enter a name e.g. Item Titel, as data type of the calculation choose date & time.

And here is the formula which you can enter:

=Title&" , "&TEXT([Start Time];"hh:mm")&" - "&TEXT([End Time];"hh:mm")

After you have sucessfully created this column you have to modify the Calendar View.

So go back to the Calendar and click modify this view. You will see an area called 'Calendar Columns', there you can specify which column should be shown

to the user in the Views Month, Week and Day. Here you have to choose your newly created Column, in my case 'Item Title'.

Click Ok and have a look at the result:

The Calculated Column has more advantages as some of think, I will write more about the formulas and constants that can be used by this column type in further posts.

cheers
