C++ 从已编译的应用程序创建windows服务
我想使用Microsoft Visual Studio 2015通过编译的C/C++代码创建服务。我编译了我的代码,并使用app executable中的C++ 从已编译的应用程序创建windows服务,c++,c,windows,service,C++,C,Windows,Service,我想使用Microsoft Visual Studio 2015通过编译的C/C++代码创建服务。我编译了我的代码,并使用app executable中的sc.exe创建了一个服务。我的代码由一个无休止的循环组成,它在时间间隔内将一个简单的字符串写入一个静态文件。创建服务并重新启动后,服务似乎会自动停止。直接运行时,可执行文件工作正常 代码如下: #include "stdafx.h" #include <string> #include <cstdio> #includ

创建了一个服务。我的代码由一个无休止的循环组成,它在时间间隔内将一个简单的字符串写入一个静态文件。创建服务并重新启动后,服务似乎会自动停止。直接运行时,可执行文件工作正常
代码如下:
#include "stdafx.h"
#include <string>
#include <cstdio>
#include <windows.h>
using namespace std;
void write_txt_file(string file_name, string input) {
/*
write a string to a specific txt file
*/
FILE *f = fopen(file_name.c_str(), "a+");
fprintf(f, "%s\n", input.c_str());
fclose(f);
}
int main(int argc, char** argv)
{
int i = 0;
while (true) {
write_txt_file("C:\\...\\Desktop\\out.txt", "Writing...#" + to_string(i));
Sleep(5000);
i++;
}
}
Windows服务不仅仅是您编写的简单可执行文件,还需要遵循特定的模式来与操作系统通信。你们可以在网站上找到所有必要的信息,此外,任何一个好的搜索引擎都会显示出无数的例子,比如 或者,您也可以使用windows服务包装器(您可以尝试——尽管需要说,我没有对其进行评估——或者搜索另一个合适的包装器)
旁注:为什么您的可执行文件停止执行?嗯,因为它没有遵循上面提到的模式,我。E没有适当地通知操作系统其状态(参见链接),因此被操作系统再次关闭(终止),因为它认为您的“服务”不可操作…Windows服务不仅仅是您编写的简单可执行文件,还需要遵循特定模式如何与操作系统通信。你们可以在网站上找到所有必要的信息,此外,任何一个好的搜索引擎都会显示出无数的例子,比如 或者,您也可以使用windows服务包装器(您可以尝试——尽管需要说,我没有对其进行评估——或者搜索另一个合适的包装器)
