程序更新

前提：更新程序使用NSIS打包后下载更新包

此处阻塞等待静默包安装覆盖原安装路径下的文件。

SHELLEXECUTEINFOA ShExecInfo = {0};

ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFOA);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = pszPath;
ShExecInfo.lpParameters = "";
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL;
ShellExecuteExA(&ShExecInfo);

WaitForSingleObject(ShExecInfo.hProcess,INFINITE);

等静默安装完成后更新界面提示
