由 纵然是瞬间 提交于 2019-12-10 10:24:36
问题 On Windows, all disk I/O ultimately happens via Win32 API calls like CreateFile , SetFilePointer , etc. Now, is it possible to intercept these disk I/O Win32 calls and hook in your own code, at run time, for all dynamically-linked Windows applications? That is, applications that get their CreateFile functionality via a Windows DLL instead of a static, C library. Some constraints that I have are: No source code: I won't have the source code for the processes I'd like to intercept. Thread

With jQuery, How Do I Intercept Hyperlink Click Events Temporarily?

由 北城余情 提交于 2019-12-10 01:52:37
问题 This question refers to affiliate marketing, but really is a generic question about intercepting hyperlinks before they go off to another site, where you can log visitor activity to a database. My affiliate marketing client had a really good question. Imagine a scenario where you have products pulled back from Amazon over its API, given a seed keyword. Now imagine a visitor clicks one of those products to view it on Amazon. The URL for that product might look like this (and this is just a

注意：proxy-target-class="true" 这是决定是走jdk代理还是spring cglib代理的。高版本的（貌似）可以忽略。 1.在spring 相关配置文件中假如如下配置： <!-- 日志时间打印 --> <aop:config proxy-target-class="true"> <!-- 这里拦截 service 包中的所有方法 --> <aop:advisor id="methodTimeLog" advice-ref="methodTimeAdvice" pointcut="execution(* *..service..*(..))"/> </aop:config> <bean id="methodTimeAdvice" class="com.ra.fire.utils.MethodTimeAdvice"> </bean> 2.实现spring aopalliance-1.0.jar 包中的的 MethodInterceptor 接口，实现类如下： package com.ra.fire.utils; import org.aopalliance.intercept.MethodInterceptor; import org.aopalliance.intercept.MethodInvocation; import org.apache

问题 i need to block any screen capture software on the computer from taking screen shots. Since all of them are work on standard API-functions, i think i could monitor and block them. I need to use C#. All i have found is how to monitor and block them in a certain program (screen capture program). They are looking for a function in the program, then they change it address on mine function address. But how can i do it, if i haven't any certain programs? I need to block anyone which tries to take a

How to use predict with multinom() with intercept in R?

由 早过忘川 提交于 2019-12-06 13:22:46
I have run the multinom() function in R, but when I try to predict on a new sample, it keeps giving an error. this is the code: library(nnet) dta=data.frame(replicate(10,runif(10))) names(dta)=c('y',paste0('x',1:9)) res4 <- multinom(y ~ as.matrix(dta[2:10]) , data=dta) #make new data to predict nd<-0.1*dta[1,2:10] pred<-predict(res4, newdata=nd) and this is the error: Error in predict.multinom(res4, newdata = nd) : NAs are not allowed in subscripted assignments I think it has to do with the intercept being included in the analysis, but not in the new prediction input.

We're building a chrome extension on top of an existing system, to help with a few tasks. It's AJAX intense and it would be far more efficient than scraping html and triggering events to intercept some of the AJAX responses. Example: Frome chrome console, networks tab, you see the beautiful JSON: How can a Chrome Extension get to that JSON ? I've tried WebRequest but it
