[challenging task] Read/Unread functionality. How?

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :SharePoint
Hi all, I have faced an interesting challenge recenlty and would like to know how would you solve the following one. So the original task is the following: There is a web part which should show items* from different SiteCollections and probably even Web Applications. We would like to add read/unread functionality (for example, if user have not read the news yet, link in this web part should be highlited. It is like in an Outlook). It should be pointed out that this solution should work under heavy load. * Item could be from the list/library or external list How you see an logical and physical architecture? Wait for you variants :)

Task assignment to user without read access in 2007 results in no email to assignee, no warning to a

It appears (from observation and searching) that SP 2007 will not send a task assignment email when the assignee does not have read access for the assigned task and there is no warning when assigning a task to someone who will be unable to read it. I have not been able to find any mentions of attempting to address this quirk by either an item event listener or a workflow that would either prevent the assignment or task the originating user to fix the issue by either changing the assignment or having them added to the appropriate group.  I could see one done badly causing a cascade of tasks. The approaches that I've thought about are: Attempt to block assignment by hooking ItemAdding and ItemUpdating on the task content type.  In ItemUpdating, you could use SPListItem.DoesUserHavePermissions since the SPListItem should be there, but you'd may have check the list since I don't think SPListItem is available at that time.  I could see this causing problems when the assignment is via workflow or something that doesn't like other code interfering with its task creation. Hooking ItemAdded and ItemUpdated to assign a new task to the assigning user to either change the assignment or have the assignee added to the users with access to the site. Define a workflow which could be enabled for a list that would check if any new or modified task is assigned to users with

Scripts not read when in head tag


I just upgraded to VS2010 if that matters.  I'm learning JQuery and noticed that scripts don't work if they're in the head tag.  Also, I need the script tag with type="text/javascript" in the head (with nothing else) in order for the JQuery scripts in the body to work.

Very bizzare, any suggestions?

With a separate script tag in the <body> with my JQuery script, this works

<head runat="server">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" />
<script type="text/javascript">

This doesn't:

<head runat="server">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" />

Read Excel file from Web Application (C#)



I have a web app where user uploads a file.

File is saved in server locally and I want to read some data from it.

Currently my development  server has office 2003.

So do I need office 2007 in order to be able to  read an excel from office 2007 ?

What are other requirements  ?

I tried a test, using

Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook wrkBook; // = new Microsoft.Office.Interop.Excel.Workbook();

wrkBook = excelApp.Workbooks.Open(@"C:\www\excel_files\b.xls", ....);

But When trying to open the file I get the error:

Exception from HRESULT: 0x800A03EC

So I'm wondering what I'm missing.
