This method causes the thread to suspend itself until the specified amount of time has elapsed . Calling Sleep allows the thread to voluntarily give up the remainder of its time-slice . The system makes the thread not schedulable for approximately the amount of time specified . That s right if you tell the system you want to sleep for 100 milliseconds, you will sleep approximately that long, but possibly several seconds or even minutes more . Remember that Windows is not a real-time operating system . Your thread will probably wake up at the right time, but whether it does depends on what else is going on in the system . You can call Sleep and pass the value in System.Threading.Timeout.Infinite (defined as -1) for the millisecondsTimeout parameter . This tells the system to never schedule the thread, and it is not a useful thing to do . It is much better to have the thread exit and then recover its stack and kernel object . You can pass 0 to Sleep . This tells the system that the calling thread relinquishes the remainder of its current timeslice, and it forces the system to schedule another thread . However, the system can reschedule the thread that just called Sleep . This will happen if there are no more schedulable threads at the same priority or higher . extract images from pdf java - pdfbox: PDFBox: Extract Content From a PDF Using Java - DZone Java extract images from pdf java - pdfbox [Solved] Extract images from pdf using pdfbox - CodeProject

The input to the aggregate function must be a base column with no manipulationit cannot be an expression (for example: SUM(qty * price)). If you want to provide the aggregate function with an expression as input, create a derived table or CTE where you assign the expression with a column alias (qty * price AS value), and in the outer query use that column as input to PIVOT's aggregate function (SUM(value)). Also, you cannot rotate attributes from more than one column (the column that appears after the FOR keyword. If you need to pivot more that one column's attributes (say, empid and YEAR(orderdate)), you can use a similar approach to the previous suggestion; create a derived table or a CTE where you concatenate the values from all columns you want to rotate and assign the expression with a column alias (CAST(empid AS VARCHAR(10)) + '_' + CAST(YEAR(orderdate) AS CHAR(4)) AS empyear). Then, in the outer query, specify that column after PIVOT's FOR keyword (FOR empyear IN([1_2004], [1_2005], [1_2006], [2_2004], ...)). c# pdf viewer winforms: How to Display a PDF file in a Panel in a WinForms app. - MSDN ... write image to pdf in java Extracting Images from PDF Documents – Snowtide
