我想向 Windows 注册表的 Run
键添加一个值,以便我的程序在启动时运行。我编写了以下代码。它编译并链接成功。当我调试该项目时,它没有给出任何错误。但是,我的 key 没有添加到注册表中。
int wmain(int argc, wchar_t* argv[])
{
HKEY key_handle;
std::wstring start_name = L"MyApplication";
std::wstring exe_path = L"C:\\Users\\user\\AppData\\Roaming\\Microsoft\\Windows\\MyApp.exe";
LONG result = RegOpenKeyEx(HKEY_CURRENT_USER, L"SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", 0, KEY_WRITE, &key_handle);
if (ERROR_SUCCESS == result)
{
result = RegSetValueEx(key_handle, start_name.c_str(),
0,
REG_SZ,
(unsigned char*)exe_path.c_str(),
exe_path.length() * sizeof(wchar_t));
if (result != ERROR_SUCCESS)
{
printf("Error setting key %d\n", GetLastError());
}
}
else
{
printf("Error opening key %d\n", GetLastError());
}
RegCloseKey(key_handle);
return 0;
}
最佳答案
您应该首先在那里创建一个键并为其设置一个值。使用以下代码片段向运行注册表添加一个键和一个值。它是用 C++ 和类编写的。
#include <Windows.h>
#include <iostream>
class startup_management
{
private:
HKEY m_handle_key = NULL;
LONG m_result = 0;
BOOL m_status = TRUE;
DWORD m_registry_type = REG_SZ;
wchar_t m_executable_path[MAX_PATH] = {};
DWORD m_size = sizeof(m_executable_path);
BOOL m_success = TRUE;
public:
BOOL check(PCWSTR arg_application_name)
{
m_result = RegOpenKeyExW(HKEY_CURRENT_USER, L"Software\\Microsoft\\Windows\\CurrentVersion\\Run", 0, KEY_READ, &m_handle_key);
m_status = (m_result == 0);
if (m_status)
{
m_result = RegGetValueW(m_handle_key, NULL, arg_application_name, RRF_RT_REG_SZ, &m_registry_type, m_executable_path, &m_size);
m_status = (m_result == 0);
}
if (m_status)
{
m_status = (wcslen(m_executable_path) > 0) ? TRUE : FALSE;
}
if (m_handle_key != NULL)
{
RegCloseKey(m_handle_key);
m_handle_key = NULL;
}
return m_status;
}
BOOL add(PCWSTR arg_application_name, PCWSTR arg_path_executable, PCWSTR arg_argument_to_exe)
{
const size_t count = MAX_PATH * 2;
wchar_t registry_value[count] = {};
wcscpy_s(registry_value, count, L"\"");
wcscat_s(registry_value, count, arg_path_executable);
wcscat_s(registry_value, count, L"\" ");
if (arg_argument_to_exe != NULL)
{
wcscat_s(registry_value, count, arg_argument_to_exe);
}
m_result = RegCreateKeyExW(HKEY_CURRENT_USER, L"Software\\Microsoft\\Windows\\CurrentVersion\\Run", 0, NULL, 0, (KEY_WRITE | KEY_READ), NULL, &m_handle_key, NULL);
m_success = (m_result == 0);
if (m_success)
{
m_size = (wcslen(registry_value) + 1) * 2;
m_result = RegSetValueExW(m_handle_key, arg_application_name, 0, REG_SZ, (BYTE*)registry_value, m_size);
m_success = (m_result == 0);
}
if (m_handle_key != NULL)
{
RegCloseKey(m_handle_key);
m_handle_key = NULL;
}
return m_success;
}
};
int wmain(int argc, wchar_t* argv[])
{
startup_management o_startup;
wchar_t executable_path[MAX_PATH];
GetModuleFileNameW(NULL, executable_path, MAX_PATH);
o_startup.add(L"Milad", executable_path, L"-foobar");
return 0;
}
然后检查以下路径:
Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
