In C# if I have a directory path and a relative file path with wildcard, "c:foobar" and "..blah*.cpp" , is there a simple way to get the list of absolute file paths, { "c:fooblaha.cpp", "c:fooblahb.cpp" } ? Background: there is a source tree that any directory can contain build definition file, which use relative path with wildcard to specify source files
在C#中,如果我有一个通配符的目录路径和相对文件路径, "c:foobar"和"..blah*.cpp" ,有没有一种简单的方法来获取绝对文件路径列表, { "c:fooblaha.cpp", "c:fooblahb.cpp" } ? 背景:有一个源代码树,任何目录都可以包含构建定义文件,它使用相对路径和通配符来指定源文件。 此处的任务是为每个构建定义文件生成所有源文件的绝对路径列表。 您可以先获取绝对路径,然后枚举匹配
How to utilize ftp? Is there a generic dll that I can use for an FTP client now that Mango has Sockets? You can download the Silverlight FTP client, you have to port the same for WP7. Try this.
如何利用ftp? 现在芒果有套接字,是否有一个通用的dll可以用于FTP客户端? 您可以下载Silverlight FTP客户端,您必须为WP7移植相同的端口。 尝试这个。
I want to copy some text files, that are written by another app, but I don't want to do anything to prevent the other app. from writing to these files. I am using File.Copy , from the System.IO namespace , C#, .Net Framework 2.0. I checked MSDN's documentation, but nothing is specifically stated about the method that File.Copy uses. Is it a wrapper to an unmanaged API call? Does F
我想复制一些文本文件,这是由另一个应用程序编写的,但我不想做任何事情来阻止其他应用程序。 从写入这些文件。 我正在使用System.IO namespace C#,.Net Framework 2.0中的File.Copy 。 我检查了MSDN的文档,但没有特别说明File.Copy使用的方法。 它是一个非托管API调用的包装? File.Copy以任何方式锁定或阻止正在复制的文件吗? 预先感谢有关这方面的任何信息。 您可以使用.Net Reflector(或其他反编译工具)
I have always used || (two pipes) in OR expressions, both in C# and PHP. Occasionally I see a single pipe used: | . What is the difference between those two usages? Are there any caveats when using one over the other or are they interchangeable? Just like the & and && operator, the double Operator is a "short-circuit" operator. For example: if(condition1 || conditi
我一直使用|| (两个管道)在OR表达式中,都在C#和PHP中。 有时我会看到使用单个管道: | 。 这两种用法有什么区别? 在使用其他产品时是否有任何注意事项,或者它们是否可以互换? 就像&和&&操作符一样,双操作符是一个“短路”操作符。 例如: if(condition1 || condition2 || condition3) 如果condition1为true,则不会检查条件2和3。 if(condition1 | condition2 | condition3) 这将检查条件2和3,
According to the documentation of the == operator in MSDN, For predefined value types, the equality operator (==) returns true if the values of its operands are equal, false otherwise. For reference types other than string, == returns true if its two operands refer to the same object. For the string type, == compares the values of the strings. User-defined value types can overload the == ope
根据MSDN中==运算符的文档, 对于预定义的值类型,如果操作数的值相等,则相等运算符(==)返回true,否则返回false。 对于字符串以外的引用类型,如果其两个操作数引用同一对象,则==会返回true。 对于字符串类型,==比较字符串的值。 用户定义的值类型可以重载==运算符(请参阅运算符)。 因此,用户定义的引用类型,尽管默认情况下==对于预定义和用户定义的引用类型的行为如上所述。 那么为什么这段代码片段无法编译
With WinForms, is there a way to be alerted to a control changing location with respect to the screen? Say you have a Form with a button on it, and you would like to know when the button is moved from its current pixel location on the screen. If the button is moved to a different location on its parent Form you could obviously use the LocationChanged event, but if the Form is moved by the user
使用WinForms,有没有办法提醒控件相对于屏幕的位置变化? 假设你有一个带有按钮的表单,并且你想知道该按钮何时从其当前像素位置移动到屏幕上。 如果将按钮移动到其父窗体上的其他位置,您显然可以使用LocationChanged事件,但如果窗体被用户移动,您如何知道该按钮已被视觉移动? 在这种简化的情况下,快速回答是监视表单的LocationChanged和SizeChanged事件,但是可以有任意数量的嵌套级别,因此监视链上的每个父级到主
Possible Duplicate: How do I write a short literal in C++? Is there a suffix for short int numerical constants in C? There are u , l , d , and f for unsigned, long, double and float, but I could not find any for short . I do some very low lever bit meddling and I need numerical constants with the size of 2 bytes. The system I work on guarantees that short int s are 2 bytes, so that is not
可能重复: 我如何在C ++中编写简短的文字? 在C中有short int数值常量的后缀吗? 有u , l , d和f表示无符号,长整数,双整数和浮点数,但我找不到任何简写 。 我做了一些非常低杠杆插手,我需要2个字节大小的数字常量。 我工作的系统保证short int是2个字节,所以这不是问题。 它是嵌入式的,所以请不要打扰有关可移植性的建议。 检查C标准,没有这样的前缀短裤。
I am trying to use Nokia N9 (meego) as a virtual Bluetooth mouse/keyboard. I am trying to use this small program as a starting point but I am running into problem: when I am running this program I get an error telling me that "Bind error (PSM 19): Permission denied". This is when a bluetooth socket is being bound to PSM 19. I get access denied when I run the program as a normal user
我正尝试将诺基亚N9(meego)用作虚拟蓝牙鼠标/键盘。 我试图用这个小程序作为出发点,但我遇到了问题:当我运行这个程序时,出现一个错误,告诉我“绑定错误(PSM 19):权限被拒绝”。 这是当蓝牙插座被绑定到PSM 19时。 当我以普通用户身份运行该程序时,也会以root身份运行时拒绝访问。 在互联网上搜索我发现低于0x1000的PSM(端口)被保留,而在其他蓝牙实现中,无法绑定到这些PSM是一个功能(例如jsr-82)。 我尝试
When understanding how primitive operators such as + , - , * and / are implemented in C, I found the following snippet from an interesting answer. // replaces the + operator int add(int x, int y) { while(x) { int t = (x & y) <<1; y ^= x; x = t; } return y; } Seems that this function demonstrates how + actually works in the background. However, it
当理解如何在C中实现+ , - , *和/等基本运算符时,我从一个有趣的答案中找到以下代码片段。 // replaces the + operator int add(int x, int y) { while(x) { int t = (x & y) <<1; y ^= x; x = t; } return y; } 似乎这个函数演示了+实际上在后台工作的方式。 但是,我理解它太困惑了。 我相信这样的操作是使用编译器生成的汇编指令很长一段时间完成的! 我的问题是: +
I've seen the word static used in different places in C code; is this like a static function/class in C# (where the implementation is shared across objects)? A static variable inside a function keeps its value between invocations. A static global variable or a function is "seen" only in the file it's declared in (1) is the more foreign topic if you're a newbie, so her
我已经在C代码的不同地方看到了static这个词; 这就像是C#中的静态函数/类(其中实现是跨对象共享的)? 函数内部的静态变量在调用之间保持其值。 静态全局变量或函数仅在其声明的文件中“可见” (1)如果你是一个新手,是更多的外国话题,所以这里是一个例子: #include <stdio.h> void foo() { int a = 10; static int sa = 10; a += 5; sa += 5; printf("a = %d, sa = %dn", a, sa); }
