创建快捷方式

注册表的方式会有权限问题，直接在启动目录下面创建快捷方式比较方便。

string appPath = w2s(getAppPath()) + "videoHelper.exe";
CreatLink2startupFolder(appPath,"videoHelper");

deleteLinkFromStarupFolder("videoHelper.lnk");

/*
	If the function succeeds, the return value is nonzero.
	If the function fails, the return value is zero (0).
*/
BOOL deleteLinkFromStarupFolder(string linkName)
{
	CHAR szStartPath[MAX_PATH] = { 0 };
	SHGetSpecialFolderPathA(NULL, szStartPath, CSIDL_STARTUP, 0);
	string path = &szStartPath[0];
	path += "\\" + linkName;
	return DeleteFileA(path.c_str());
}

bool CreatLink2startupFolder(string appPath, string linkName)
{
	string appName = "\\" + linkName + ".lnk";
	HRESULT hr = CoInitialize(NULL);
	if (SUCCEEDED(hr))
	{
		IShellLink *pisl;
		hr = CoCreateInstance(CLSID_ShellLink, NULL,
			CLSCTX_INPROC_SERVER, IID_IShellLink, (void**)&pisl);
		if (SUCCEEDED(hr))
		{
			IPersistFile* pIPF;

			//这里是我们要创建快捷方式的原始文件地址  
			pisl->SetPath(s2w(appPath).c_str());
			hr = pisl->QueryInterface(IID_IPersistFile, (void**)&pIPF);
			if (SUCCEEDED(hr))
			{
				//这里是我们要创建快捷方式的目标地址  
				CHAR szStartPath[MAX_PATH] = { 0 };
				SHGetSpecialFolderPathA(NULL, szStartPath, CSIDL_STARTUP, 0);
				strcat_s(szStartPath,MAX_PATH, appName.c_str());

				USES_CONVERSION;
				LPCOLESTR lpOleStr = A2COLE(szStartPath);
				pIPF->Save(lpOleStr, FALSE);
				pIPF->Release();
			}
			pisl->Release();
		}
		CoUninitialize();
	}

	return true;
