Sep 19, 2016 · Create a WinForm barcode reader on Windows with webcam and C#. ... Read bitmap and display results on TextBox: private void ... The logic behind the calculation of the grouping factor here is a bit tricky . You calculate a row number (rn) based on the order of mnth, partitioned by sgn (trend) . This means that, for each trend, you can have multiple consecutive groups, naturally with gaps between them . Now try to think of the way the mnth value increments within a particular trend versus how rn increments . Both continue to increment by one unit as long as you re still in the same consecutive group . Once you have a gap, mnth increments by more than one unit, whereas rn keeps incrementing by one . You can conclude that if you subtract rn months from mnth, the result for each consecutive group will be constant and unique . As I mentioned, the logic here is tricky and can be hard to grasp . To better understand it, I suggest that you pull SalesGrp s query aside and play with it . For example, return the row number itself (as opposed to using it in a calculation), and so on . Finally, create the SalesTrends view to group the data by sgn and grp, returning the ranges of consecutive months with the same trend . distinguishing barcode scanners from the keyboard in winforms capturing Barcode scan using C# | .Net Trails

In fact, you can think of CTEs as inline views that exist only in the scope of the outer query . If you think about it, other than allowing a modular development approach, you have no real reason to create the intermediate views in the solution . Instead, you should just create the final one SalesTrends which will be defined by a CTE developed using a modular approach . Run the following code to alter the SalesTrends view, implementing it with multiple CTEs defined in the same WITH statement instead of defining multiple views: Iterates over all <th>Easy Actions</th> quote elements in </tr> the document <xsl:for-each select="//quote"> <tr> <td><xsl:value-of select="@symbol"/></td> ALTER VIEW dbo.SalesTrends AS WITH SalesRN AS ( SELECT mnth, qty, ROW_NUMBER() OVER(ORDER BY mnth) AS rn FROM dbo.Sales ), SalesTrendSgn AS ( SELECT Cur.mnth, Cur.qty, SIGN(Cur.qty - Prv.qty) AS sgn FROM SalesRN AS Cur LEFT OUTER JOIN SalesRN AS Prv ON Cur.rn = Prv.rn + 1 ), SalesGrp AS ( SELECT mnth, sgn, DATEADD(month, -1 * ROW_NUMBER() OVER(PARTITION BY sgn ORDER BY mnth), mnth) AS grp FROM SalesTrendSgn ) SELECT CONVERT(VARCHAR(6), MIN(mnth), 112) AS start_range, CONVERT(VARCHAR(6), MAX(mnth), 112) AS end_range, CASE sgn WHEN -1 THEN 'down' WHEN 0 THEN 'same' WHEN 1 THEN 'up' ELSE 'unknown' END AS trend FROM SalesGrp GROUP BY sgn, grp; GO CREATE TABLE dbo.T1 ( keycol INT NOT NULL PRIMARY KEY, datacol VARCHAR(10) NOT NULL ); winforms textbox barcode scanner Bar Code Scan windows forms - MSDN - Microsoft
