CodeProject: ExifLibrary for .NET. Free source code and programming help
To extract Exif metadata from a JPEG/Exif image, create an instance of the ExifData class with the path to the image file. The ExifData class reads the APP1 section, and extracts all Exif tags and also the embedded thumbnail (if any). For ease of use, this Exif library converts Exif tags to either .NET native types or custom classes. Date fields are returned as DateTime structures, GPS coordinates are wrapped with custom GPSLatitudeLongitude classes, etc.
NCDevGuys' ramblings on connected bits.... : InfoPath : Retrieve and Send Data from/to a SharePoint 2007 Workflow
Yes, I know this title sounds a bit odd, and the real title should be ‘When you are using an InfoPath task edit form, how do you use InfoPath data connection bindings to both retrieve and send data to a SharePoint 2007 workflow?’
So one day I was building an InfoPath 2007 task edit form and I wanted to send data to this form from inside of my workflow by using something like:
taskProperties.ExtendedProperties[“txtProductDescription”] = “Product ABC”;
I implemented an ItemMetadata.xml file with an ‘ows_txtProductDescription’ field, added a secondary data connection for it in my InfoPath form and followed all the normal steps and when I opened the form when my task was created, the data was there as expected.
However, what I didn’t realize was that when I closed the form and completed the task and then re-opened the form just to look at my previous settings, the data was gone! The form appeared as if it were a new form with default settings. To make matters worse, inside of the workflow I discovered that I could not use the task After properties to get the data out of the txtProductDescription field, it was always null. And this is where my multi-day odyssey of searching for the answer began.
To make things simple here, I’m just going to start with a simple form that has no binding and show you how to set things up. I hate to admit it took me several days and talking to several people to figure this out, so I hope it helps you shorten your path to a solution also.
Technologies Used:
* Microsoft Office SharePoint Server 2007 Enterprise Edition, SP1
* InfoPath 2007 – Browser enabled forms
* Visual Studio 2008 SP1 / C#

Chaks' Corner | Using KeywordQuery to search in your SharePoint site
There are various ways that you can query the Search Service in your SharePoint site:
1) Using the Search Web Service
2) Using the SharePoint Object Model
There are yet again two ways you can use the Search, using the Object Model:
i) KeywordQuery
ii) FullTextSqlQuery
I think it is a good option to use Object Model when you want to customize the Search (mostly in your WCM websites), and KeywordQuery comes in very handy!
Using KeywordQuery to search is pretty simple! (provided you have set up your Search properly)

Item ID in display and edit forms « Path to SharePoint
A frequent request: have the ID displayed when viewing an individual item, in display form (DispForm.aspx) and edit form (EditForm.aspx). This is for example useful when a team uses the default SharePoint ID as identifier in an Issue Tracking list.
Note: the ID cannot be displayed in NewForm.aspx, simply because the ID doesn’t exist yet when you add a new item.

HowTo: Senden von Emails testen ohne Mailserver | Code-Inside Blog
mails mit .NET zu versenden ist recht einfach, wenn es allerdings darum geht, den generierten Emailtext zu testen, dann wird es manchmal etwas schwierig.
Vor allem wenn das Entwicklungssystem keinen Zugriff auf den richtigen Email-Server hat, geht es meist nur auf "gut Glück".
Es gibt allerdings einen einfachen Web.Config Eintrag der es erheblich vereinfacht - die PickupDirectoryLocation.
CodeProject: Blending HTML into Silverlight pages seamlessly. Free source code and programming help
The scenario that this article solves is the following: I am developing a simple image viewer page with a menu on the top-left. The menu is developed using Silverlight. By clicking the menu button, users can view a resizable image on the main page. In addition to showing an image, I also want the main page to be able to show an HTML content. Moreover, I want to use a Silverlight control to show the image or the HTML content.
There are two issues to be solved:
1. There is no existing HTML Silverlight control that can render an HTML page.
2. How to route the OnClick event from the Menu control to the Image control.
In the following sections, I will show you an idea of solving the above problems.
I assume readers are familiar with ASP.NET/C#, Silverlight, Visual Studio, JavaScript, and DHTML.
The wrong way to iterate through SharePoint SPList Items
There are multiple ways to iterate through the items of a SharePoint list by using the SharePoint Object Model. One approach - which I’ve seen before in a real life SharePoint Application - may work fine on the developers machine or on very tiny lists. But it is going to ruin your performance once executed on a list that exceeds a couple of hundred items.
Writing to the SharePoint Unified Logging Service – Windows Live
Writing to the SharePoint Unified Logging Service
SharePoint uses a logging service that makes entries in the log files located at Program Files\Common Files\Microsoft Shared\web server extensions\12\LOGS. Out-of-the-box, SharePoint logs almost everything to these files, and I have seen them get quite large. Therefore, you should "throttle" the log writing, which can be done in the "Diagnostic Logging" section of the Central Administration site.
Once you discover the log files, you'll want to be able to write to them from your own features. This is a pretty easy thing to do, because the SharePoint SDK has a complete sample with code you can reuse. I use this code regularly in my features, so I have packaged it into a class that you can download here. Simply add the class to your project and then you can write to the logs using something like the following code.
TraceProvider.RegisterTraceProvider();
TraceProvider.WriteTrace(TraceProvider.TagFromString("XXXX (must be 4 letter tag)"), TraceProvider.StringToSeverity("Exception or Information"), Guid.NewGuid(), "Method Name", "Assembly Name", "Project Name", "Message");
TraceProvider.UnregisterTraceProvider();
Once you start writing to the log files, you'll discover that there is no easy way to view them. SharePoint does not have a log viewer built into the Central Administration web site. I've written an additional feature for viewing logs that you can download from my CodePlex project.
Display site members from AD Groups « Bits of Sharepoint
I recently have to do this for a client. The web part is suppose to display a list of all users from the Sharepoint Security groups for every site. The out of the box webpart(Site Users) will display only the name of the AD group and not the members within it.
To get started, it is easier if you installed the Webpart templates for VS.NET
Created a solution using webpart template and you are ready to go.

Moldenco: SPSecurity.RunWithElevatedPrivileges to update SPRoleAssignment of an SPListItem
When you write custom code in Sharepoint webparts, your code will run with your credentials.
Not everybody has Full Control, so when a user has only read rights, the code will throw an access denied error when the code needs access to objects that are not in the scope of the user credentials.... (example: add the username in the ReadBy properties of an item).
