SPListItemVersion and Dates

It seems SPListItemVersion objects are not displaying dates in the correct timezone. I had to convert the date to a DateTime object and the use the ToLocalTime method to get the correct date out.

Outlook 2007 and HTML email

Well, this can seem to be a little of topic :)

I was generating HTML e-mails that are sent via SharePoint (SendEmail method). But the e-mail wouldn´t render correctly in Outlook 2007. The e-mail was just cut off in Outlook 2007. I ran the HTML that was generated in validators and making sure that all tags was closed but nothing seemed to make me come closer to the solution.

Finnaly I stumbled across the solution! The problem was that I created a long string without linebreaks (\r\n)!

So my guess is that Outlook 2007 reads the HTML into a pre-definied string buffer and the parses it for output and in this case the HTML I sent was to long for this buffer.

Unable to break role inheritance

A customer had a problem to break the inheritance from the parent web. The error message on the first page was "500 Internal server error" and when breaking the inheritance from Site Settings was:

“Cannot complete this action.
Please try again. at Microsoft.SharePoint.Library.SPRequestInternalClass.ResetSecurityScope(String bstrUrl, UInt32 dwObjectType, String bstrObjUrl, Guid guidDoc, Boolean bUnique, Boolean bCopyRoleAssignments, Guid& pguidScopeId, Int32& piError)
at Microsoft.SharePoint.Library.SPRequest.ResetSecurityScope(String bstrUrl, UInt32 dwObjectType, String bstrObjUrl, Guid guidDoc, Boolean bUnique, Boolean bCopyRoleAssignments, Guid& pguidScopeId, Int32& piError) “

Inspired by this solution I just broke the inheritance of the permission levels and inherited it again to fix the issue of not being able to break the role inheritance.

Fast recap:
Browse to http:////_layouts/role.asxp
Break the inheritance
Enable the inheritance again

Another surprise in SharePoint

I have a list with versioning enabled and a "Multiple line of text" field that can not be updated via the UI. The field is also configured to append text to the current text.

When updating the field and using SPItem.SystemUpdate(false) (in code) the field don´t get a new entry (as it does when editing a field of this type via the UI). Nope, it simply overwrites the current text and updates the field.

One solution to this is to concatenate the old value with the new, with the drawback that the datestamp will always stay the same until a new version of the item is created.
I removed the append option and did the appending of the field myself instead.

"Copy to GAC" problem with WSPBuilder

See this thread for a solution to the problem. It seems that all application pools needs to be running for it to work.

"The given key was not present in the dictionary"

Error message when activating a feature with field definition included. Could not display any site columns via the site either. Fired up SPM and browsing the Fields collection and got an error message about a field type not correctly installed.

It turned out I had misspelled "Number" to lowercase "number" in my field definition file. Amend the line and upgraded the solution and the problem was resolved

WSPBuilder: Unicode characters

Got this error message from WSPBuilder when building a new WSP file:
"The filename of the CAB file must not contain Unicode characters!"

I had some some swedish characters in my projectfolder name. I removed it and updated the SLN file with the new path. Problem solved.

File attachment and Infopath 2003 SP1

We have been working on a small project using Infopath 2003 and MOSS to create a faster way to input information in a list. Among the challenges (which was quite a few despite it was software from MS on both "sides") faced was how to enable uploading a file while submitting information to a list.

Infopath 2003 provides a File Attachment Control which enables the end-user to select and attach a file to the form. Infopath automatically encodes the file in Base64 and adds a dynamic header in the front of the file. So we wanted to use the "AddAttachment" web service available to post the file, one of the parameters is a Base64 encoded string. Great! Well, the header added by Infopath is also included in the encoding. We only have Jscript or VBScript to use in Infopath 2003 if we don´t want to start to deploy extra code on the clients (which I try to prefer to stay away from) and the support for decoding/encoding files in those languages are not to great.



So our solution is to extract the filename from the header (code below) and the attach a list item event receiver for "ItemAttachmentAdded" which decode the file, removes the header and saves the file again serverside.



Here is the code for extracting the filename from an Infopath Base64 encoded attachment:



dim node

Set node = XDocument.DOM.documentElement.selectSingleNode("/my:myFields/my:FileAttchmentControl")



If(node.text <> "") Then


'typecast the node to base64 as Infopath doesn't do this in node definition

node.DataType = "bin.base64"

'convert base64 node value to binary and store in nodeValue byte array

nodeValue = node.nodeTypedValue



dim convertByteArrayToHexString

convertByteArrayToHexString = ""

For intCounter = 1 to LenB(nodeValue)

convertByteArrayToHexString = convertByteArrayToHexString & Right("0" & Hex(AscB(MidB(nodeValue, intCounter, 1))), 2)

If(intCounter = 100) Then 'Assuming that the header is no longer that 100 bytes
exit for
end if

Next

dim filenameBuffer
dim filename
filename = ""
filenameBuffer = 0

'The length of the filenamebuffer is stored on pos 20-24 (byte), which means 41.47 in Hex and 1 as startpos for Arrays

filenameBuffer = getFilenameBuffer(convertByteArrayToHexString,41,47)



'Read the filename from position (49 to filenamebuffer * unicode - "\n") as end char

filename = getFileName(convertByteArrayToHexString,49,filenameBuffer*4 + 49 - 2)

Function getFilenameBuffer(data,startLoop,stopLoop)
dim k

dim filenameBuffer

for k = startLoop to stopLoop step 2

dim y1
dim y2
dim y3

y1 = Mid(data,k,2)
y2 = CLng("&h" & y1)
y3 = y3 + Int(y2)

filenameBuffer = y3

next

getFilenameBuffer = filenameBuffer

End Function

Function getFileName(data,startLoop, stopLoop)
dim k

dim filename

for k = startLoop to stopLoop step 4

dim h1
dim h2
dim h3

h1 = Mid(data,k,2)
h2 = CLng("&h" & h1)
h3 = Chr(h2)

if(h3 <> "") then
filename = filename & Cstr(h3)
end if

next

getFileName = filename
End Function

Additional user information import with BDC

Been working on an secondary connection to a SQL Server database that will be used to add more information to the user profile properties. Solution includes the BDC application but foremost setting the correct access permission for the account accessing the BDC application.

I use "RevertToSelf" in the ADF which makes the access to the BDC run with the account for the service "Office SharePoint Search Server".

So the account needs "Execute" permissions for the BDC application and all entities, DBDataReader to the SQL Server (or any other read permission) and finally "Manager User Profiles" under "Personalization Permissions". When troupbleshooting this the ULS is yor friend.

Make sure that no other accounts gets permission to the application in BDC, you want to avoid to expose the BDC application to the built-in web parts.

Moving to WSPBuilder

Attended the first Sweden SharePoint User Group Malmö meeting (phew, that was long) yesterday. Karsten was there and talked about his tools WSPBuilder and SPM2007.

We have been using STSDev for sometime now, but it feels like the development have stalled and other participants also noted that you need to fix bugs in the tool to make it work in different situations. So we have decided to switch to WSPBuilder instead for coming projects. Hopefully it cuts down the time developers needs to write code in the OM.

Response to "JQuery for Everyone: Total Calculated Columns"

Finally there is somekind of light-weight workaround for Calculated Columns and Totals using jQuery and the beloved CEWP. Find the original post here: http://www.endusersharepoint.com/?p=1106 (great work by the way :) ).

I have made an extension to this, so instead of just calculating the last column one can add any column for a total sum.
I use the sortable element ID to find the cellIndex for all rows that needs to be calculated (diidSortMean = a calculated column with the namne "Mean"). I use IE Dev Toolbar for that purpose.

The script currently calculates a total for three columns, but can easily modified in the CalcGroup function. My list is also expanded as default, will do more testing in the weekend.

If you find bugs, please leave a comment.

Getting picky in CAML - Good

I have code in Excel that uses XMLHTTP to call SharePoints web services. The code contains a CAML query where I had a field reference to a Choice field , , this column has been converted to a Text (Single line of text) column and the query didn´t return any items anymore when running against MOSS 2007 instead of Wss 2.0. Then I updated the field reference to and the query returned items again.

Sad

Patrick Tisseghem has suddenly passed away and left a big hole in the Sharepoint community. He was one of the first bloggers I found before the release of MOSS 2007 and I was fortune to once meet him during a training session. My thoughts goes out to his family.

STSADM and SharePoint Designer operations failed

I was getting error messages (cannot delete folder "WEBNAME") for deleteweb operation for stsadm and when opening the web in SharePoint Designer (SD) I got "There is no web "/XXX/YYY". Couldn´t delete documents but the web was browsable in SD (error code 16388). I finally tried to attach to the database in Visual Studio and got an error message about full transaction logs on the database server. In this case we configured "simple mode" instead and all operations completed sucessfully.

So know your DBA and have them close :)
