MFC 文件操作出现 an unnamed file contains a n ivvalid path 实在没钱了 求救

图片说明
其中m _ ppp 是哪个编辑框的cstring变量
以下是哪个按钮的clicked函数

```void CFileDlg::OnButton1()
{
// TODO: Add your control notification handler code here
char writeBuffer[500];

char readBuffer[500];

LONGLONG lOff = 0;

CFile file(m_ppp, CFile::modeCreate | CFile::modeReadWrite);   


memset(writeBuffer, 'c', sizeof(writeBuffer));   

file.Write(writeBuffer, sizeof(writeBuffer));   

while (true)   
{   

    file.Seek(lOff, CFile::begin);   

    int nRet = file.Read(readBuffer + lOff, 100);   

    lOff += nRet;   

    if (nRet < 100)   
        break;   
}   


file.Close();

}

提示是路径有问题,windows下用e:\12.txt 或e:/12.txt,试试

将通道嵌入结构

<div class="post-text" itemprop="text"> <p>How do I embed a channel in a struct in <a href="http://en.wikipedia.org/wiki/Go_%28programming_language%29" rel="nofollow">Go</a>?</p> <p>Why the inconsistency between the map syntax:</p> <pre><code>var m map[string]int </code></pre> <p>and channel,</p> <pre><code>var m chan int </code></pre> <p>?</p> <p>To clarify, in Go it is possible to embed a type in another type. The embedder type gains access to all the methods defined on the embedded type, but it is also possible to refer to the embedded type explicitly by the name of its type. Therefore, the inconsistency between the map type declaration and channel type declaration is confusing for someone who would like to refer to an embedded channel type.</p> </div>

一种在Go中对结构片段进行排序的灵活而优雅的方法[关闭]

<div class="post-text" itemprop="text"> <p>Let us say that we have a fairly complicated <code>struct</code> with numerous fields, that I need to sort in several places according to different criteria, e.g.</p> <pre><code>type MySuperType struct { x0, x1, x2, x3 xType // possibly even more fields } // sort 1: ascending x0, then descending x1, then more stuff // sort 2: if x4==0 then applyCriteria2a else applyCriteria2b func f1(mySuperSlice []MySuperType) { // sort 'myList' according sort #1 // do something with the sorted list } func f2(mySuperSlice []MySuperType) { // sort 'myList' according sort #2 // do something with the sorted list } func f3(mySuperSlice []MySuperType) { // sort 'myList' according sort #1, note: we use sort #1 again! // do something with the sorted list } </code></pre> <p><strong>Proposed solution 1:</strong><br> Create a new type (alias of <code>[]MySuperType</code>) that implements <code>sort.Interface</code> for each sorting criteria required.<br> Problems: (i) there is some duplicated code, as the functions <code>Len</code> and <code>Swap</code> are going to be identical (ii) there is going to be a bunch of new types lying around that do not help with the overall readability of the program --- these new types don't really represent anything, plus the only thing that really matters is the <code>Less</code> function.</p> <p><strong>Proposed solution 2:</strong><br> Use <code>sort.Slice</code><br> It would be the perfect solution (see <a href="https://stackoverflow.com/a/42872183/3923424">this answer</a>), but from my understanding, the sorting function has to be specified inline (I get an error <code>invalid receiver type []T ([]T is an unnamed type)</code> when I tried to define it elsewhere, which means that I need to define an alias for <code>[]T</code> and we are back to solution 1).<br> Now, the problem with defining the function inline is that (i) given the complexity of <code>MySuperType</code>, the function can be very long and (ii) the functions are going to be duplicated in several place (e.g. in <code>f1</code> and <code>f3</code> in my example above) -- much more annoying that in solution 1 as the sorting functions can be long and complex.<br> <sub>Note: (i) would not be that much of an issue if we did not have (ii) actually</sub></p> <p><strong>Question:</strong><br> Given my current understanding and knowledge of Go, I would use solution 1.<br> But does anyone knows a different approach that elegantly solves this problem or suggestions to improve the drawbacks listed above?</p> </div>

So I just passed []Sentence as an argument and solve the problem that I need to.

嵌入式新手求教,在IAR下对两个工程合并,编译出现未知错误。。

我是嵌入式刚开学的新手 在我们嵌入式课程上面,我们通过IAR对NXP LPC2478进行开发和编译学习。。 课程中收到了一些实验例程,其中就包括LCD 和 SD卡读取的相关例子。。 在学习中,我希望把SD卡读写和LCD显示整合在一起,能实现读取SD卡中数据显示在LCD屏幕的功能。。 在两个工程合并中,我用LCD的例子为基础,依次添加SD卡中相关的.c文件和.h文件。。。在添加SD卡的例子过程中,出现的未知错误,添加mmc.c的时候编译出错,出错提示如下 Error[Pa055]: expected a type attribute C:\Program Files\IAR Systems\Embedded Workbench 5.4 Evaluation\arm\inc\NXP\iolpc2460.h 2734 Error[Pe079]: expected a type specifier C:\Program Files\IAR Systems\Embedded Workbench 5.4 Evaluation\arm\inc\NXP\iolpc2460.h 2734 Error[Pe040]: expected an identifier C:\Program Files\IAR Systems\Embedded Workbench 5.4 Evaluation\arm\inc\NXP\iolpc2460.h 2734 Error[Pe168]: a function type is not allowed here C:\Program Files\IAR Systems\Embedded Workbench 5.4 Evaluation\arm\inc\NXP\iolpc2460.h 2734 Error[Pe147]: declaration is incompatible with "union <unnamed> volatile _A_<error>" (declared at line 4079) C:\Program Files\IAR Systems\Embedded Workbench 5.4 Evaluation\arm\inc\NXP\iolpc2460.h 4080 等这几类错误,一共一百多个错误,查找的源头是 Embedded Workbench 5.4 Evaluation\arm\inc\NXP\iolpc2460.h 在添加各个.c时编译时没有问题的,但是在main函数 #include “mmc.h” 时 就是会出现错误。 我在整合时看到,SD卡的例子用的头文件时<nxp/iolpc2468.h> 而 LCD则用的是另外的头文件“LPC23XX.h”,“LPC2468.h” 所以在此希望高人能帮助下我,谢谢。。

PHP - 尝试从带有附件的脚本发送电子邮件,但它不附加Hi

<div class="post-text" itemprop="text"> <p>I have a file that I am creating on the fly like this:</p> <pre><code>// Create and save the string on the file system $str = "Business Plan: Some more text"; $fp = fopen("alex.txt", 'w+'); fwrite($fp, $str); // email with the attachment $to = 'alex.genadinik@gmail.com'; $subject = 'Your business plan attached'; //create a boundary string. It must be unique //so we use the MD5 algorithm to generate a random hash $random_hash = md5(date('r', time())); //define the headers we want passed. Note that they are separated with $headers = "From: BusinessPlanApp@example.com"; //add boundary string and mime type specification $headers .= " Content-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\""; //read the atachment file contents into a string, //encode it with MIME base64, //and split it into smaller chunks $attachment = chunk_split(base64_encode(file_get_contents('alex.txt'))); $contents = "some contents of the email"; mail($to, $subject, $contents, $headers); </code></pre> <p>And the file is saving to the file system AND an email is getting sent to me with the right body and subject.</p> <p>The only thing going wrong is the attachment is unnamed file of zero bytes. Any idea why that might happen? Is it a permissions issue? Or something in my email?</p> <p>Thanks!</p> </div>

再不跳槽,应届毕业生拿的都比我多了!

跳槽几乎是每个人职业生涯的一部分,很多HR说“三年两跳”已经是一个跳槽频繁与否的阈值了,可为什么市面上有很多程序员不到一年就跳槽呢?他们不担心影响履历吗? PayScale之前发布的**《员工最短任期公司排行榜》中,两家码农大厂Amazon和Google**,以1年和1.1年的员工任期中位数分列第二、第四名。 PayScale:员工最短任期公司排行榜 意外的是,任期中位数极小的这两家公司,薪资...

华为初面+综合面试(Java技术面)附上面试题

华为面试整体流程大致分为笔试,性格测试,面试,综合面试,回学校等结果。笔试来说,华为的难度较中等,选择题难度和网易腾讯差不多。最后的代码题,相比下来就简单很多,一共3道题目,前2题很容易就AC,题目已经记不太清楚,不过难度确实不大。最后一题最后提交的代码过了75%的样例,一直没有发现剩下的25%可能存在什么坑。 笔试部分太久远,我就不怎么回忆了。直接将面试。 面试 如果说腾讯的面试是挥金如土...

上班一个月,后悔当初着急入职的选择了

最近有个老铁,告诉我说,上班一个月,后悔当初着急入职现在公司了。他之前在美图做手机研发,今年美图那边今年也有一波组织优化调整,他是其中一个,在协商离职后,当时捉急找工作上班,因为有房贷供着,不能没有收入来源。所以匆忙选了一家公司,实际上是一个大型外包公司,主要派遣给其他手机厂商做外包项目。**当时承诺待遇还不错,所以就立马入职去上班了。但是后面入职后,发现薪酬待遇这块并不是HR所说那样,那个HR自...

副业收入是我做程序媛的3倍,工作外的B面人生是怎样的?

提到“程序员”,多数人脑海里首先想到的大约是:为人木讷、薪水超高、工作枯燥…… 然而,当离开工作岗位,撕去层层标签,脱下“程序员”这身外套,有的人生动又有趣,马上展现出了完全不同的A/B面人生! 不论是简单的爱好,还是正经的副业,他们都干得同样出色。偶尔,还能和程序员的特质结合,产生奇妙的“化学反应”。 @Charlotte:平日素颜示人,周末美妆博主 大家都以为程序媛也个个不修边幅,但我们也许...

离职半年了,老东家又发 offer,回不回?

有小伙伴问松哥这个问题,他在上海某公司,在离职了几个月后,前公司的领导联系到他,希望他能够返聘回去,他很纠结要不要回去? 俗话说好马不吃回头草,但是这个小伙伴既然感到纠结了,我觉得至少说明了两个问题:1.曾经的公司还不错;2.现在的日子也不是很如意。否则应该就不会纠结了。 老实说,松哥之前也有过类似的经历,今天就来和小伙伴们聊聊回头草到底吃不吃。 首先一个基本观点,就是离职了也没必要和老东家弄的苦...

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...

Java岗开发3年,公司临时抽查算法,离职后这几题我记一辈子

前几天我们公司做了一件蠢事,非常非常愚蠢的事情。我原以为从学校出来之后,除了找工作有测试外,不会有任何与考试有关的事儿。 但是,天有不测风云,公司技术总监、人事总监两位大佬突然降临到我们事业线,叫上我老大,给我们组织了一场别开生面的“考试”。 那是一个风和日丽的下午,我翘着二郎腿,左手端着一杯卡布奇诺,右手抓着我的罗技鼠标,滚动着轮轴,穿梭在头条热点之间。 “淡黄的长裙~蓬松的头发...
