"2009 CWE/SANS Top 25 Most Dangerous Programming Errors" list published!

2009-11-06T08:10:00Z

The 2009 CWE/SANS Top 25 Most Dangerous Programming Errors is a list of the most significant programming errors that can lead to serious software vulnerabilities. They occur frequently, are often easy to find, and easy to exploit. They are dangerous because they will frequently allow attackers to completely take over the software, steal data, or prevent the software from working at all. The list is the result of collaboration between the SANS Institute, MITRE, and many top software security experts...(read more)

Validate that file name before uploading a file to the SharePoint library!

2009-10-29T13:36:00Z

In a course of time I’ve seen many ways to validate a name of a file which is being uploaded to the SharePoint library. It’s somehow not that well known that there is a SPEncode class in Microsoft.SharePoint.Utilities namespace which can really help us to implement the file name validation which covers all of the cases which SharePoint does not like. Take a look at the SPEncode class. Hence, take a look at the whole Microsoft.SharePoint.Utilities namepace, there are some cool things there...(read more)

Microsoft Windays 09: MOSS 2007 and Enterprise Application Integration

2009-03-27T21:43:00Z

One of the important developers conferences in Europe, Microsoft Windays , is traditionally being held in a beautiful Croatian coast town of Opatija (April 20-24th 2009). It is primarily a developers and architects conference, although this year there is a business part too, called "Windays Business". Well, I'll be at a tech part :) My session this time is about MOSS 2007 and EAI. We can, without thinking twice over it, say that Enterprise Application Integration (EAI) has never had...(read more)

Develop and deploy a SharePoint Event Receiver from the scratch

2009-03-12T14:02:10Z

There are many information peaces on the internet how to build a decent working event receiver in SharePoint – mainly good, but still, only peaces. I’ll try to present here a complete and quick “how to” guide - from making decision which event we want to catch until the event deployment. What you will not find here is a description of developing event handlers using Windows SharePoint Services 3.0 Tools: Visual Studio 2008 Extensions – you cannot use them in x64 environments, and “Null reference...(read more)

Including duplicates in SharePoint search results

2009-02-11T10:02:10Z

If you have two very similar files, it can happen that the SharePoint search API recognize them as duplicate files. This all happens because of the the iFilter architecture on which the SharePoint Search relays on: from each file is first the pure text being extracted, and then, this text is indexed. Now, if two texts are very similar – SharePoint is going to consider them as duplicates. So, it can happen that you have a PowerPoint presentation and a Word document with a very similar content...(read more)

Cool Taskbar bug

After restarting a Windows 2003 Server, my Taskbar was duplicated. Just so. Killing Explorer.exe process and staring it again helped, but it was cool while it lasted…...(read more)

Working with user roles and permissions in SharePoint Object Model part 2

2008-06-13T14:27:00Z

In my previous post , I have explained how to work with user roles and permissions in SharePoint object model, how to access and create SPGroup objects (SharePoint groups) on the fly, and how to assign Permission Leves (a.k.a Role Definitions) to these SPGroup (or SPUser) objects. Ok, but, what if existing, predefined Permission levels (Full Control, Design, Manage Hierarchy, Approve, Contribute, Read, Restricted Read, Limited Access, View Only) are not enough? You can always create your own Premission...(read more)

Which Microsoft Office version can be used with WSS 3 and MOSS 2007?

2008-06-04T07:06:00Z

Yesterday, I was explaining the user-experience differences between Office 2003 and Office 2007 to a customer. What can be done with 2003, where do I definitely need 2007. And then came the question if the Office XP can be used. I didn't know, and sincerely, it has been some time since I last saw a Office XP installation. So I tried, and yes, it can. Not with all the nice-to-have features as with Office 2003 and especially Office 2007, but, it works. Microsoft describes integration between Office...(read more)

Working with user roles and permissions in SharePoint Object Model

2008-05-18T19:20:00Z

In this example, I'll create a SharePoint group using the Object Model, add few users in that group - which will be single users as well as the whole AD groups, create a folder inside the existing SharePoint Document library, break it's permissions inheritance to the parent Document Library, and create new permissions model adding to a single user full rights and to newly created SharePoint group read only rights. On the end, I'll check permissions for any given user if (s)he has rights...(read more)

Read the BDC data from MOSS Object Model

2008-04-16T21:51:00Z

So, what do you do the first when you want to create a rock-solid BDC system with your SharePoint? If your BDC is going to fetch it's data from the web service, you will of course first create the service, which must contain at least two methods: the IdEnumerator and SpecificFinder compliant methods (to simplify: IdEnumerator compliant method returns just a set of the "primary keys" for all the data your BDC system is offering, and SpecificFinder compliant method returns all the data...(read more)

MOSS, Sharepoint Object Model and CAML: Recursive search (search in subfolders) in document libraries and lists

2008-03-28T07:56:00Z

One of the nice features in SharePoint Object Model is querying lists and document libraries with CAML queries with GetItems method. One of the overloads of this method allows (a part of a) CAML query as parameter SPList.GetItem(SPQuery), meaning everything inside <Where>...</Where> element - basically - you don't pass the whole <Query> element, just it's <Where> child. You'll notice that when you execute such a query, all items which would match the criteria,...(read more)

Importing linked lists into existing MOSS 2007 site

2008-03-10T19:46:00Z

Picture this situation: you have two operational MOSS 2007 sites, possibly at two different MOSS servers. Now, you have to copy two SharePoint lists from one site to another, retaining all additional information like field names, descriptions, views... Well, it's easy: you'll save the lists as templates on the first site, download the templates, upload the templates onto another server (if we're talking about two different MOSS servers), create new lists from templates and voila - that's...(read more)
