No. Yes. If the class implements IDisposable, then you need the "using" statement. If it doesn't, you don't using statements instead. Hopefully not a big deal. Exactly. Look at the documentation. Every .NET class has on the first doc page for that class a complete description of all classes it inherits and interfaces it implements. If the class implements IDisposable, it will say so there. Alternatively, you could always just look for the Dispose() or IDisposable.Dispose() interface in the class methods. Generally speaking it should. However, I can't rule out the possibility of a class that requires explicit closing for best results. A Close() method may have other semantics than

Exception handling could any one send me the best practices of exception handling in cs code and also in stored procedures for 4 + years .net developer range for a real time examples, this link may help you: http: / / www.codeproject.com / KB / exception / RealTimeDebugger.aspx Thanks A well-designed set of error handling code blocks can make a example, you can programmatically check for a condition that is likely to occur without using exception handling. In other situations, using exception handling to catch an error condition is appropriate. The following example uses an if statement check whether a connection is closed. You can use this method instead of throwing an exception if the connection is not closed. A few basic design concepts will make your program most common "bad code" that you can introduce in your projects, when it comes to exception handling. Don't throw new Exception() Please, don't do it. Exception is a too broad class, and it's hard

crashing at this line below and throwing this kind of error (The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))) newChartObject = chartObjects.Add(0, 100, 300, 300); The first thing I is all my code for this function, I wanted to throw this code in a class of its own, a class design to handle the creation of the excel chart but out of desperation decided to move it back to my class where I handle the creation of the excel doc, thinking that would work but it swith back workSheet_range = getWorkSheet(1).get_Range("B4", "B100"); newChartObject = chartObjects.Add(0, 100, 300, 300); <- -- -- -- - Exception thrown here newChartObject.Chart.ChartWizard(workSheet_range, Excel.XlChartType.xlLine, 1, Excel.XlRowCol.xlColumns, misValue, misValue, misValue, misValue, misValue, misValue, misValue); } - -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Here is my code for my class Create Excel doc using System; using System.Windows.Forms; using System.Collections.Generic; using System Linq; using System.Text; using System.Reflection; using Excel = Microsoft.Office.Interop.Excel; namespace securities_Research { class CreateExcelDoc { private Excel._Application app = null; / / Creates the excel doc private Excel._Workbook workbook = null
