问题 My goal is to to convert a .txt file on an FTP page to a simple String for easy manipulation. The specific .txt file is here: ftp://ftp.nasdaqtrader.com/SymbolDirectory/nasdaqlisted.txt.

问题 see test code: package main import "fmt" func main() { i := 10 closure1 := func() { fmt.Printf("closure, i: %d\n", i) i = 15 } closure1() fmt.Printf("in main, i: %d\n", i) closure2 := func(x int) { fmt.Printf("function call, pass parameter, i: %d\n", x) } i = 20 closure1() closure2(i) } I think the output of the closure2 should be 20, but the real result is 15, i do not know why???? anybody can help me , please see my comment in my code, thanks in advance. 回答1: The problem is that your first

问题 I'm having some trouble with figuring out a way of unsubscribing from some anonymous delegate events that i found in a pre-made helper file that helps allow movement of controls at run time. The reason i want to unsubscribe to these events is so that the control (in this case buttons) will become locked again and not able to be moved. Here is the method in the helper class: public static void Init(Control control) { Init(control, Direction.Any); } public static void Init(Control control,

问题 Is this allowed? : class A; void foo() { static A(); } I get signal 11 when I try to do it, but the following works fine: class A; void foo() { static A a; } Thank you. 回答1: Nope. There is no such thing as an "anonymous object" in C++. There is such a thing as defining an object to type A that is immediately discarded; what you've written is an expression that returns an A object that's never assigned to a variable, like the return code of printf usually is never assigned or used. In that

问题 I am trying to implement a simple websockets application that can send messages from one endpoint to a specified session established elsewhere. So far I have been able to use the annotation @SendToUser() in order for a client to subscribe to a channel (as discussed in this question: Spring Websockets @SendToUser without login?) However, I now want to create a separate endpoint that, when called, looks up a user associated with data passed into this endpoint and sends a message to that user

问题 In Xcode and Instruments I see UILabel (CALayer) using large amounts of virtual memory (Anonymous VM). I see about 235 KB of virtual memory per UILabel . I think this perhaps is a new issue with iOS 7.1 or 7.1.1. Is this expected? I created a simple program that creates 500 UILabels and Instruments shows 115MB of memory used. At about 1500 labels the application is terminated by the OS. for (int i = 0; i < 500; i++) { index = (int)[self.items count]; index++; frame = CGRectMake(10.0, 20, 300

问题 Craigslist has a nice feature where when you respond to a poster you respond to an email such as job-fepsd-1120347193@craigslist.org . The email is then in turn directed to the real email. I am looking for a couple pointers on how to do this with PHP. Thanks, Levi 回答1: This is usually done by piping an e-mail address (often, a catch-all address) to PHP. Here's a tutorial on doing it that should get you started in the right direction. 回答2: The most probable solution is that they do email
