I don't see much advantage in using it, except that it allows for shorter code. It doesn't support dynamic pivoting, and underneath the covers, it applies very similar logic to the one I presented in the last solution. So you probably won't even find noticeable performance differences. At any rate, here's how you would pivot the OpenSchema data using the PIVOT operator: SELECT objectid, attr1, attr2, attr3, attr4, attr5 FROM dbo.OpenSchema PIVOT(MAX(value) FOR attribute IN([attr1],[attr2],[attr3],[attr4],[attr5])) AS P; Before You Begin. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-2 how to extract image from pdf using pdfbox in java PDFBox: Extract Content From a PDF Using Java - DZone Java

There is a question on StackOverFlow.com asking if there was a way to replace an image in a PDF file. PDFOne can parse through all content elements in a ... The SimpleSpinLock implementation is very simple . If two threads call Enter at the same time, Interlocked.Exchange ensures that one thread changes m_resourceInUse from 0 to 1 and sees that m_resourceInUse was 0, and this thread then returns from Enter so that it can continue executing the code in the AccessResource method . The other thread will change m_resourceInUse from a 1 to a 1 . This thread will see that it did not change m_resourceInUse from a 0, and this thread will now start spinning continuously calling Exchange until the first thread calls Leave . When the first thread is done manipulating the fields of the SomeResource object, it calls Leave, which internally calls Thread.VolatileWrite and changes m_resourceInUse back to a 0 . This causes the spinning thread to then change m_resourceInUse from a 0 to a 1 and this thread now gets to return from Enter so that it can access SomeResource object s fields . There you have it . This is a simple implementation of a thread synchronization lock . The big potential problem with this lock is that it causes threads to spin when there is contention for the lock . This spinning wastes precious CPU time, preventing the CPU from doing other, more useful work . As a result, spin locks should only ever be used to guard regions of code that execute very quickly . And spin locks should not typically be used on single-CPU machines, as the thread that holds the lock can t quickly release it if the thread that wants the lock is spinning .
