Monitoring application calls to DLL

走远了吗. 提交于 2019-11-26 12:23:48
问题 In short: I want to monitor selected calls from an application to a DLL. We have an old VB6 application for which we lost the source code (the company wasn\'t using source control back then..). This application uses a 3rd party DLL. I want to use this DLL in a new C++ application. Unfortunately the DLL API is only partially documented, so I don\'t know how to call some functions. I do have the functions signature. Since the VB6 application uses this DLL, I want to see how it calls several

问题 How can i monitor requests on WKWebview? I\'v tried using NSURLprotocol (canInitWithRequest) but it won\'t monitor ajax requests (XHR), only navigation requests(document requests) 回答1: Finally I solved it Since I don't have control over the web view content, I injected to the WKWebview a java script that include a jQuery AJAX request listener. When the listener catches a request it sends the native app the request body in the method: webkit.messageHandlers.callbackHandler.postMessage(data);

问题 What\'s a monitor referred to in concurrent programming in Java? When I read that \"every object has associated a monitor\" what does it meaning? Is it a special object? 回答1: A monitor is mechanism to control concurrent access to an object. This allows you to do: Thread 1: public void a() { synchronized(someObject) { // do something (1) } } Thread 2: public void b() { synchronized(someObject) { // do something else (2) } } This prevents Threads 1 and 2 accessing the monitored (synchronized)

问题 For mastering of some technology you have to know how it\'s made at one abstraction level lower. In case of multithreading programming, it will be good to know about synchronization primitives. Here is the question, how implemented Lock (Monitor) in .NET? I\'m intrested in such points: - does it utilize OS objects?; - does it require user mode or kernel mode?; - what is overhead for threads that are waiting for lock?; - in what cases threads queue that awaiting for the lock could be violated?

问题 Is there any way to start/lunch a program through Process in another screen? Someone asked that here but there was no answer. Note: it is not a form in my app, I\'m asking about running an external program in another screen! 回答1: Since the window is not yours, you can only move it by invoking the Windows API. You will have to do this: Launch the process. Use FindWindow to retrieve the handle to the window. If the window doesn’t exist yet, the process hasn’t created it yet; sleep for 500ms and
