To acquire (lock) a Mutex, call the WaitOne method, inherited from the WaitHandle class. Presumably this remarkably unspecific name hasn t been supplemented with a more mnemonic method like Acquire or Open because Microsoft wanted to remind you that the call may not return immediately, that WaitOne will block until you have acquired the lock, and also to remind you that you can pass the Mutex to WaitHandle.WaitAll or WaitHandle.WaitAny. Or perhaps it s just an unthinking reflection of the Windows API. In any case, you acquire a Mutex by waiting for it, and you release (unlock) a Mutex by calling the ReleaseMutex instance method.

Very few people get it absolutely right at the design stage. Most of us amend our code as requirements change or as we gain a deeper understanding of the nature of the problem we are addressing. As we amend our code, it can easily drift beyond our control. A method is added here, and a new class there, and gradually our system begins to decay. As you have seen already, your code can point the way to its own improvement. These pointers in code are sometimes referred to as code smells that is, features in code that may suggest particular fixes or at least call you to look again at your design. In this section, I distill some of the points already made into four signs that you should watch out for as you code.

C# : Adding Text Annotation + Signature to a PDF Document

An event is either set (signaled) or reset (not signaled) A thread that waits on a signaled event passes right on through, without blocking Conversely, a thread that waits on an unsignaled event will block until some other thread sets the event to the signaled state Events may either reset automatically, after a single thread has passed through, or they may require manual reset An auto reset event will only let one thread through at a time: each thread that passes through resets the signal, so that any threads that wait (or are waiting) on the event block (or stay blocked) until you set the signal again Conversely, setting a manual reset event will unblock all threads that may be waiting for the event, and subsequent waits will not block until you call the Reset method to reset the event to the unsignaled state In 1.

Providing a static spreadsheet for users to view in the browser may have its place, but overall, most users want to change data in a spreadsheet, re-sort the data, or even filter the data to better serve their needs. After all, spreadsheets are all about what-if analysis and making business decisions after evaluating data. While you cannot provide total access to all the features users might normally use directly within Excel, you can at least provide users with the option to change values associated with specific cells while viewing the spreadsheet. Besides, if they really need to have total control over the design of the spreadsheet and change the formatting, structure, or even the formulas used by the spreadsheet, they can always click the Open in Excel option mentioned earlier and

Duplication is one of the great evils in code. If you get a strange sense of d j vu as you write a routine, chances are you have a problem. Take a look at the instances of repetition in your system. Perhaps they belong together. Duplication generally means tight coupling. If you change something fundamental about one routine, will the similar routines need amendment If this is the case, they probably belong in the same class.

x, there are two types of event wait classes that descend directly from WaitHandle: the (SystemThreading) AutoResetEvent and the ManualResetEvent Both classes are still supported in 20, but they now descend from the new (SystemThreading) EventWaitHandle class, which descends directly from WaitHandle EventWaitHandle is not an abstract class: you can create an EventWaitHandle as either a manual reset event or as an auto-reset event, by passing the appropriate EventResetMode enum to the EventWaitHandle constructor Neither AutoResetEvent nor ManualResetEvent can be used across processes you have to use the EventWaitHandle As with mutexes, the EventWaitHandle can be anonymous, and used entirely within a process, but you will usually use the overloads that take a name and that can be accessed from other processes The EventWaitHandle constructor has overloads that can either wrap an existing named OS event or can create and wrap a new named OS event.
