c - 如何在Win32中安装/卸载Windows服务？

我正在尝试创建一个Win32程序，该程序可以删除特定路径中的临时文件。

但是我实际上在代码中的安装/卸载功能上遇到了麻烦。

我正在使用Visual Studio 2012，当我启动调试过程以测试代码时，调试窗口将立即关闭。

也许问题不是来自VS 2012，而是我的代码？

这里是：

#include <Windows.h>
#include <stdio.h>

# define MY_SERVICE_NAME "DiskCleaner"
# define MY_SERVICE_DISPLAY_NAME "Nettoyeur de disque"

SERVICE_STATUS_HANDLE my_ServiceStatusHandle;
BOOL bRunning;
BOOL InstallMyService();
BOOL DeleteMyService();
void WINAPI ServiceCtrlHandler(DWORD Opcode);
void WINAPI ServiceMain(DWORD argc, LPTSTR *argv);

/* INSTALL THE SERVICE */
BOOL InstallMyService()
{
    char strDir[MAX_PATH];
    SC_HANDLE hSCManager;
    SC_HANDLE hService;
    LPCTSTR lpBinaryPathName;

    GetCurrentDirectory(MAX_PATH, strDir);
    strcat(strDir, "\\AutoClean.exe");

    hSCManager = OpenSCManager (NULL, NULL, SC_MANAGER_ALL_ACCESS);

    if (hSCManager == NULL)
        return (FALSE);

    lpBinaryPathName=strDir;

    hService = CreateService(
        hSCManager,                             MY_SERVICE_NAME,

    if (hService == NULL)
        return (FALSE);

    CloseServiceHandle(hService);
    return (TRUE);
}

/* DELETE THE SERVICE */
BOOL DeleteMyService()

    if (hSCManager == NULL)

    while (bRunning)
    {
        printf("\nOK just to test if this part works well before implementing my cleaning part\n");

    return (EXIT_SUCCESS);
}

最佳答案

在主要功能中，您会遇到以下错误：

if (strcmp(argv[1], "-i"))

if (strcmp(argv[1], "-d"))

此条件为FALSE，因此不会执行您的InstallMyService（）/ DeleteMyService（）。

同样，出于复杂性考虑，您忘记了关闭服务管理器句柄。
