I have written a Windows service that allows me to remotely run and stop applications. These applications are run using CreateProcess, and this works for me because most of them only perform backend processing. Recently, I need to run applications that present GUI to the current log in user. How do I code in C++ to allow my service to locate the currently active desktop and run the GUI on it?
我已经写了一个Windows服务,允许我远程运行和停止应用程序。 这些应用程序使用CreateProcess运行,这对我来说很有用,因为它们大多数只执行后端处理。 最近,我需要运行向当前登录用户呈现GUI的应用程序。 如何在C ++中编写代码以允许我的服务找到当前活动的桌面并在其上运行GUI? Roger Lipscombe的回答是,使用WTSEnumerateSessions查找正确的桌面,然后使用CreateProcessAsUser在该桌面上启动应用程序(将STARTUPINFO结
We have a simple C++ program which send/simulate return key events to an active window using keybd_event. keybd_event(VK_RETURN, 0x1c, 0, 0); This works fine for all kind of windows apps. But we like to send the keyboard event to a 3rd party app like GTA (the game) - and this does not work. GTA does not receive the keyboard event. Why does GTA not receive the keyboard event? Is there a way
我们有一个简单的C ++程序,它使用keybd_event发送/模拟返回键事件到活动窗口。 keybd_event(VK_RETURN, 0x1c, 0, 0); 这适用于所有类型的Windows应用程序。 但我们喜欢将键盘事件发送给第三方应用程序,如GTA(游戏) - 这是行不通的。 GTA不会收到键盘事件。 为什么GTA没有收到键盘事件? 有没有办法让它使用keybd_event? 还是有任何其他解决方案将事件发送到所有类型的应用程序(使用通用Windows或C ++标准库)?
I have this code to listen to keyboard events of the active window: #include<X11/Xlib.h> #include<stdio.h> #include<stdlib.h> #include <iostream> #include <thread> using namespace std; #define IR_MODE 8192 #define SHIFT_MODE 16 #define US_MODE 0 static int ErrorHandler (Display *display, XErrorEvent *error) { cout<< "An error ocurred. We don't know any
我有这个代码来监听活动窗口的键盘事件: #include<X11/Xlib.h> #include<stdio.h> #include<stdlib.h> #include <iostream> #include <thread> using namespace std; #define IR_MODE 8192 #define SHIFT_MODE 16 #define US_MODE 0 static int ErrorHandler (Display *display, XErrorEvent *error) { cout<< "An error ocurred. We don't know anything."; return 0; }
I'm developing and app for Bada OS and i need use vectors and other standar structures from stl. But when i write: #include <vector> The Bada sdk throws me an error: unresolved inclusion: vector I'm looking for a solution on Internet and the solution always is include the stl's path on the configuration of the project (Bada IDE are derivated from Eclipse). But i don't
我正在开发和应用Bada OS,我需要使用向量和stl的其他标准结构。 但是当我写: #include <vector> 巴达sdk给我一个错误: unresolved inclusion: vector 我正在寻找Internet上的解决方案,并且解决方案始终是在项目配置中包含stl的路径(Bada IDE源自Eclipse)。 但我不知道该路径在哪里,我试图包括我发现的所有路径(在minGW,bada目录等),如果包含它,编译器不运行。 请帮帮我! (抱歉我的英文不好) &l
What is the correct zeromq message pattern to choose to implement server, which needs to handle 2 way communication between N-clients (client can issue requests and server can issue notification, which has to be reliable. Thus pub/sub in not going to work here)? What I did: server has REP to handle client requests, REQ to issue notification to client, SUB to get some events. client has REQ to i
什么是选择实现服务器的正确的zeromq消息模式,它需要处理N个客户端之间的双向通信(客户端可以发出请求并且服务器可以发出通知,这必须是可靠的,因此pub / sub不会工作这里)? 我做了什么:服务器有REP处理客户端请求,REQ发送通知给客户端,SUB获取一些事件。 客户端有REQ发送请求到服务器,REP接收来自服务器的通知,SUB获取一些事件然后:服务器通过REP和SUB套接字轮询到POOLIN客户端通过REP和SUB套接字轮询到POOLIN

这个问题在这里已经有了答案: 需要帮助mod 1000000007问题3答案 如何在C ++中计算A,B,C <= 10 ^ 18的(A * B)%C? 2个答案 在x86-64平台上对C(++)中的64位无符号参数计算(a * b)%m FAST? 4个答案 这里的基本思想是首先定义一个非溢出的addmod函数,它在算法中利用负数。 然后使用位操作定义timesmod 。 时间复杂度是O(N) ,其中N是使用的位数(在这种情况下是64)。 #include <iostream> using
I have recently been exploring C++ some after using C# exclusively for quite awhile. I'm using Visual Studio 2013 and the one thing that is bugging me to death is the inability to commit an Intellisense suggestion by pressing the space bar. I have tried to edit the commit character list in Options -> Text Editor -> C/C++ -> Advanced to accept the space bar but so far I've had n
我最近在使用C#之后一直在探索C ++。 我使用的是Visual Studio 2013,唯一让我烦恼的是无法通过按空格键来提交Intellisense建议。 我试图在选项 - >文本编辑器 - > C / C ++ - >高级中编辑提交字符列表来接受空格键,但到目前为止我没有运气。 来自C#这是非常加重。 有谁知道是否有可能做出这样的改变? 我知道我可以使用Tab或Enter,但在我看来,使用Space更加流畅。 任何信息将不胜感激。 更新:空间似乎
What are the C++ rules for calling the superclass constructor from a subclass one? For example, I know in Java, you must do it as the first line of the subclass constructor (and if you don't, an implicit call to a no-arg super constructor is assumed - giving you a compile error if that's missing). Base class constructors are automatically called for you if they have no argument. If y
从子类调用超类构造函数的C ++规则是什么? 例如,我知道在Java中,您必须将其作为子类构造函数的第一行(如果您不这样做,则假定隐式调用no-arg超级构造函数 - 如果缺少它,会给您一个编译错误) 。 如果没有参数,基类构造函数会自动调用。 如果要使用参数调用超类构造函数,则必须使用子类的构造函数初始化列表。 与Java不同,C ++支持多重继承(无论好坏),所以基类必须按名称引用,而不是“super()”。 class SuperC
In my C++ code I use templates a lot.. that might be an understatement. The end result is that the type names take more than 4096 characters and watching the GCC output is painful to say the least. In several debugging packages like GDB or Valgrind one can request that C++ types not be demangled. Is there a similar way to force G++ to output only mangled type names, cutting on all the unecess
在我的C ++代码中,我使用了很多模板..这可能是轻描淡写。 最终的结果是类型名称需要超过4096个字符,并且至少可以说看GCC输出是痛苦的。 在像GDB或Valgrind这样的几个调试软件包中,可以要求C ++类型不要被取消。 有没有类似的方法来强制G ++ 只输出破损的类型名称,切割所有不必要的输出? 澄清 由于我给出的第一个答案,我发现问题并不清楚。 考虑下面的MWE: template <typename T> class A { public:

以下代码: #include<iostream> #include<regex> using namespace std; int main(int argc, char *argv[]) { regex reg("/"); string s = "Split/Values/Separated/By/Slashes"; sregex_token_iterator it{std::begin(s), std::end(s), reg, -1}; sregex_token_iterator end; while(it != end) { cout << *it++ << endl; } return 0; } 应输出: Split
