Recently in a WEB project, you need to call OCX to connect the card reader. Originally do not want to use OCX technology, because the ActiveX technology is produced by Microsoft, so that the entire system can only use IE browser (other browsers can be in the form of plug-ins to support OCX calls). But trying a lot of ways to invoke client DLL discovery is not going to make sense. Finally helpless under, only then intends to study the OCX technology. Online all say that the ActiveX technology is

Pdf. js tutorial The charm of the pdf. js framework is implemented for HTML5, without any local support, and the browser compatibility is also good. There is only one requirement: the browser supports HTML5! (However, for earlier versions of IE, we can only mourn !) It is said that IE9 and above are OK, because I use IE11 locally, so I only tested it on IE11 and

"explorer", URL, null, sw_show); return L ""; };Then we compile the project, and a file named ACExtensionDemo.dll is generated, and the file is copied to the extensions in the installation directory.So we can invoke the extension method we just wrote in the script, and here we use the method called extern "C" __declspec (dllexport) wchar* Sum (WCHAR *params) as an example to illustrate this.The script should write like thisThe object that constructs the extension method, where the function is

will delete all attributes whose subscript is greater than or equal to the new length. Another point is how the length value of the array comes from. It is correct to add one of the largest numeric index values, but if the empty slot is also counted, the length value is the number of elements in the array. The above figure explains: From the values, we can see that an array a, a [0], and a [10] have been assigned values. At this time, the length of a is 11, there are nine empty slots in the mi

state of the thread and restores its control over the CPU to continue execution. This I/O pattern is the usual synchronous I/O (synchronous I/O). asynchronous I/O: When a thread encounters an I/O operation, it does not block the completion of the I/O operation or the return of the data, but simply sends the I/O request to the operating system and proceeds to the next statement. When the operating system completes an I/O operation, the thread that notifies the I/O operation as an event
