before Except_handler3 restores the value of EBP from [ebx+10h], what is [ebx+10h]? You can first determine whether EBX is the ebx that is set when you enter Except_handler3, and it points to _exception_registration. _EXCEPTION_REGISTRATION+10H is _EXCEPTION_REGISTRATION!EBP, isn't it? This EBP is a function frame saved when entering the main function, so the variables in the main function can be obtained by offsets relative to EBP.As for the GetExceptionInformation () function, the XPointer ad

this property may be modified by someone. NBSp 8. The scopes associated to closures are active. 9. In a function, the number of arguments is obtained by arguments.length, and the number of parameters is obtained by the length property of the function. The difference between 10.call () and apply (), call () all arguments after the first parameter are the arguments to pass in, and apply places all the arguments to be passed in an array. 11.ECMASCRIPT5 has a bind method that binds a

uses the non-downward nature of the scope chain (the noun I take). ), that is, the following scopes can be accessed above, but the above cannot be accessed below. Of course, this is only a condition of the closure, the closure of the more important is the external function to hold the internal function of a nested function reference, because the closure is not the main discussion of this article (PS: When talking about encapsulation), so just look at the following example:1 function foo () {2 v

when the initial state of the file is basically ordered is low. In the beginning of the hill, the increment is larger, more groups, fewer records per group, so the direct insertion within the group is faster, and then the incremental di gradually reduced, the number of groups gradually decreased, and the number of records of the group gradually increased, but because already according to Di-1 as a distance row order, so that the file is closer to the orderly state, So the new trip sort proc

Pop (); The method may throw emptystackexception ... } In fact, an exception is often caused by another cause exception, because cause itself will have cause, and so on, forming a chain exception (Chained Exceptions).

Overloading of functions. the signature of a function includes the name of the function and its arguments, including the type of the parameter and the keyword (out/ref), excluding the return type of the function.5. Delegation. A type that stores references as functions. The life of a delegate is similar to a function, without a f

startprocesslocked to start the process of application A, Before startprocesslocked, however, it is possible to start provider in the same process, without having to put provider in another process. Originally ContentProvider can provide data to different clients in different processes, but if not necessary, ContentProvider is called within the same process to save more resources. So when Getcontentproviderimpl, this judgment is the Canrunhere function in Contentproviderrecord. The following co
