我正在调试一个程序并想使用 windbg 在 Secur32!ImpersonateSecurityContext 设置一个断点。我的高级 Windows 调试 一书告诉我，我应该能够使用此命令 bp Secur32!ImpersonateSecurityContext 设置断点。不幸的是，它对我来说失败了。
我确实检查了我的符号路径，我相信它是正确的。如果我在 windbg 中运行 x Secur32!*，我也会得到一些符号。

我在那里找不到符号 Secur32!ImpersonateSecurityContext。所以，我认为这就是我无法设置断点的原因。 MSDN确实声称 ImpersonateSecurityContext 位于 Secur32.dll 中。我不敢相信微软故意去掉这个符号，因为它是一个非常受欢迎的功能，许多程序都在使用它。我一定是遗漏了一些简单的东西。
有什么想法吗？
最佳答案
不要无助。您已经有了这些工具。
如果您已经在调试调用 ImpersonateSecurityContext 的程序，请找到对 ImpersonateSecurityContext 的调用并查看调用 的目标> 说明是。
如果您没有调用 ImpersonateSecurityContext 的程序，那么就去做一个吧。
#include <windows.h>
#include <security.h>
int __cdecl main(int, char **)
{
ImpersonateSecurityContext(NULL);
return 0;
}
编译此程序，在 ImpersonateSecurityContext 调用上设置断点，然后运行它。当断点命中时，单步查看它会将您带到哪里。这就是 ImpersonateSecurityContext 所在的位置。
关于windows - 在 Secur32!ImpersonateSecurityContext 处设置断点，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/8003107/
我有一个Ruby程序，它使用rubyzip压缩XML文件的目录树。gem。我的问题是文件开始变得很重，我想提高压缩级别，因为压缩时间不是问题。我在rubyzipdocumentation中找不到一种为创建的ZIP文件指定压缩级别的方法。有人知道如何更改此设置吗？是否有另一个允许指定压缩级别的Ruby库？ 最佳答案 这是我通过查看rubyzip内部创建的代码。level=Zlib::BEST_COMPRESSIONZip::ZipOutputStream.open(zip_file)do|zip|Dir.glob("**/*")d
我需要在客户计算机上运行Ruby应用程序。通常需要几天才能完成(复制大备份文件)。问题是如果启用sleep，它会中断应用程序。否则，计算机将持续运行数周，直到我下次访问为止。有什么方法可以防止执行期间休眠并让Windows在执行后休眠吗？欢迎任何疯狂的想法;-) 最佳答案 Here建议使用SetThreadExecutionStateWinAPI函数，使应用程序能够通知系统它正在使用中，从而防止系统在应用程序运行时进入休眠状态或关闭显示。像这样的东西:require'Win32API'ES_AWAYMODE_REQUIRED=0x0

我正在查看instance_variable_set的文档并看到给出的示例代码是这样做的:obj.instance_variable_set(:@instnc_var,"valuefortheinstancevariable")然后允许您在类的任何实例方法中以@instnc_var的形式访问该变量。我想知道为什么在@instnc_var之前需要一个冒号:。冒号有什么作用？ 最佳答案 我的第一直觉是告诉你不要使用instance_variable_set除非你真的知道你用它做什么。它本质上是一种元编程工具或绕过实例变量可见性的黑客攻击
我想设置一个默认日期，例如实际日期，我该如何设置？还有如何在组合框中设置默认值顺便问一下，date_field_tag和date_field之间有什么区别？ 最佳答案 试试这个:将默认日期作为第二个参数传递。youcorrectlysetthedefaultvalueofcomboboxasshowninyourquestion. 关于ruby-on-rails-date_field_tag，如何设置默认日期？[rails上的ruby]，我们在StackOverflow上找到一个类似的问
这似乎非常适得其反，因为太多的gem会在window上破裂。我一直在处理很多mysql和ruby-mysqlgem问题(gem本身发生段错误，一个名为UnixSocket的类显然在Windows机器上不能正常工作，等等)。我只是在浪费时间吗？我应该转向不同的脚本语言吗？ 最佳答案 我在Windows上使用Ruby的经验很少，但是当我开始使用Ruby时，我是在Windows上，我的总体印象是它不是Windows原生系统。因此，在主要使用Windows多年之后，开始使用Ruby促使我切换回原来的系统Unix，这次是Linux。Rub

我在Rails应用程序中使用CarrierWave/Fog将视频上传到AmazonS3。有没有办法判断上传的进度，让我可以显示上传进度如何？ 最佳答案 CarrierWave和Fog本身没有这种功能；你需要一个前端uploader来显示进度。当我不得不解决这个问题时，我使用了jQueryfileupload因为我的堆栈中已经有jQuery。甚至还有apostonCarrierWaveintegration因此您只需按照那里的说明操作即可获得适用于您的应用的进度条。 关于ruby-on-r
之前在培训新生的时候，windows环境下配置opencv环境一直教的都是网上主流的vsstudio配置属性表，但是这个似乎对新生来说难度略高(虽然个人觉得完全是他们自己的问题)，加之暑假之后对cmake实在是爱不释手，且这样配置确实十分简单(其实都不需要配置)，故斗胆妄言vscode下配置CV之法。其实极为简单，图比较多所以很长。如果你看此文还配不好，你应该思考一下是不是自己的问题。闲话少说，直接开始。0.CMkae简介有的人到大二了都不知道cmake是什么，我不说是谁。CMake是一个开源免费并且跨平台的构建工具，可以用简单的语句来描述所有平台的编译过程。它能够根据当前所在平台输出对应的m
