View 1 RepliesI am reading datas from MSWord Document. I know how to read the file. the sample text in my MSword. C# code review checklist. My current client uses PSP extensively, so I've been putting together a checklist for reviewing C# code for use on our new project.
1.Are exceptions used to indicate error rather than returning status or error codes?
2.Are all classes and public methods commented with .NET style comments? Note that <summary> comments should discuss the "what" of public methods. Discussion of "how" should be in <remarks> blocks or in-line with the code in question?
3.Are method arguments validated and rejected with an exception if they are invalid?
4.Are Debug.Asserts used to verify assumptions about the functioning of the code? Comments like, "j will be positive" should be rewritten as Asserts.
5.Do classes that should not be instantiated have a private constructor?
6.Are classes declared as value types only infrequently used as method parameters, returned from methods or stored in Collections?
7.Are classes, methods and events that are specific to an assembly marked as internal?
8.Are singletons that may be accessed by multiple threads instantiated correctly?
9.Are methods that must be overriden by derived classes marked as abstract?
10.Are classes that should not be overriden marked as sealed?
11.Is "as" used for possibly incorrect downcasts?
12.Do classes override ToString instead of defining a Dump method for outputting the object's state?

View 3 RepliesI have a link here that works perfect for calling the postback close that I need to happen:
<a href="javascript:parent.__doPostBack('Close','')"><asp:Label ID="Label5" runat="server" Text="Close Me"></asp:Label></a>

I.e., when I have completed my tasks in the application code, call parent.doPostBack as my last function call, which closes the window in question.
