添加应用启动（注册表） [英] Add Application to Startup (Registry)

问题描述

我想加我的软件，注册表，我已经找到了codeS，我可以使用，但不完整的工作code C / C ++是新的给我，并不能在创建它的一些作品我自己的。但这里的基本思想是：检查的注册表项设置如果不创建它。

I'm trying to add my software to registry, I have found some pieces of the codes I can use but not full working code C/C++ is new to me and can't create it on my own. But here is the basic idea: Check if reg key set if not create it.

我可以用这个code，让我的程序位置：

I was able to get my program location using this code:

TCHAR szPath[MAX_PATH];
GetModuleFileName(NULL,szPath,MAX_PATH);

，并能创建的关键是：（不知道这是正确的方式）

And was able to create the key with: (Not sure if it's the right way)

HKEY newValue;
RegOpenKey(HKEY_CURRENT_USER,"Software\\Microsoft\\Windows\\CurrentVersion\\Run",&newValue);
RegSetValueEx(newValue,"myprogram",0,REG_SZ,(LPBYTE)szPath,sizeof(szPath));
RegCloseKey(newValue);
return 0;

现在缺少的，一个小的检查，如果关键已不存在...

What is missing, A small check if the key isn't already there...

感谢您！

推荐答案

下面是一些code，它有可能你想要做什么。呼叫 RegisterProgram 为您的EXE自注册本身会自动被启动时，该函数调用用户登录 GetModuleFileName 然后调用 RegisterMyProgramForStartup 另一个名为辅助函数，它的写入注册表。

Here's some code that likely does what you want. Call RegisterProgram for your EXE to self-register itself for automatically being started when the user logs in. This function calls GetModuleFileName and then invokes another helper function called RegisterMyProgramForStartup that does the writing to the registry.

呼叫 IsMyProgramRegisteredForStartup（L文件my_program）来检测是否登记确实存在，并显示有效。

Call IsMyProgramRegisteredForStartup(L"My_Program") to detect if the registration actually exists and appears valid.

一个快速的注意。检查，看看是否存在的关键实际上再次写出来之前，对性能的影响是微不足道的。你可以只调用RegisterProgram盲目，如果它已经存在，它将覆盖的关键。检测如果注册存在用于初始化你的UI复选框启用或禁用自动启动是有用的。 （你是给你的用户一个选择，不是因为我恨自动安装自己没有给我一个选择自动运行的应用程序。）

One quick note. The performance impact of checking to see if the key exists before actually writing it out again is negligible. You could just call RegisterProgram blindly and it will overwrite the key if it already exists. Detecting if the registration exists is useful for initializing your UI checkbox that enables or disables auto-start. (You are giving your users a choice, right? Because I hate apps that automatically install themselves to run automatically without giving me a choice.)

BOOL IsMyProgramRegisteredForStartup(PCWSTR pszAppName)
{
    HKEY hKey = NULL;
    LONG lResult = 0;
    BOOL fSuccess = TRUE;
    DWORD dwRegType = REG_SZ;
    wchar_t szPathToExe[MAX_PATH]  = {};
    DWORD dwSize = sizeof(szPathToExe);

    lResult = RegOpenKeyExW(HKEY_CURRENT_USER, L"Software\\Microsoft\\Windows\\CurrentVersion\\Run", 0, KEY_READ, &hKey);

    fSuccess = (lResult == 0);

    if (fSuccess)
    {
        lResult = RegGetValueW(hKey, NULL, pszAppName, RRF_RT_REG_SZ, &dwRegType, szPathToExe, &dwSize);
        fSuccess = (lResult == 0);
    }

    if (fSuccess)
    {
        fSuccess = (wcslen(szPathToExe) > 0) ? TRUE : FALSE;
    }

    if (hKey != NULL)
    {
        RegCloseKey(hKey);
        hKey = NULL;
    }

    return fSuccess;
}

BOOL RegisterMyProgramForStartup(PCWSTR pszAppName, PCWSTR pathToExe, PCWSTR args)
{
    HKEY hKey = NULL;
    LONG lResult = 0;
    BOOL fSuccess = TRUE;
    DWORD dwSize;

    const size_t count = MAX_PATH*2;
    wchar_t szValue[count] = {};


    wcscpy_s(szValue, count, L"\"");
    wcscat_s(szValue, count, pathToExe);
    wcscat_s(szValue, count, L"\" ");

    if (args != NULL)
    {
        // caller should make sure "args" is quoted if any single argument has a space
        // e.g. (L"-name \"Mark Voidale\"");
        wcscat_s(szValue, count, args);
    }

    lResult = RegCreateKeyExW(HKEY_CURRENT_USER, L"Software\\Microsoft\\Windows\\CurrentVersion\\Run", 0, NULL, 0, (KEY_WRITE | KEY_READ), NULL, &hKey, NULL);

    fSuccess = (lResult == 0);

    if (fSuccess)
    {
        dwSize = (wcslen(szValue)+1)*2;
        lResult = RegSetValueExW(hKey, pszAppName, 0, REG_SZ, (BYTE*)szValue, dwSize);
        fSuccess = (lResult == 0);
    }

    if (hKey != NULL)
    {
        RegCloseKey(hKey);
        hKey = NULL;
    }

    return fSuccess;
}

void RegisterProgram()
{
    wchar_t szPathToExe[MAX_PATH];

    GetModuleFileNameW(NULL, szPathToExe, MAX_PATH);
    RegisterMyProgramForStartup(L"My_Program", szPathToExe, L"-foobar");
}

int _tmain(int argc, _TCHAR* argv[])
{
    RegisterProgram();
    IsMyProgramRegisteredForStartup(L"My_Program");
    return 0;
}
