the filename is not always passed as parameter in actual.
you have with yourself a list of programs associated with some specific file type in ur registry.the system checks for the file extension then starts a process associated with.but always passing it as parameter is not true. The operating system has its own architecture to call a program from its assembly.

Windows 将文件传递给程序的方式因应用程序而异。此行为由注册表控制。
对于 Excel，他们使用所谓的 DDE 来实现此目的。这就是为什么您在命令行上看不到任何内容。
How Windows passes the file to the program varies from one application to another. This behavior is controlled by the registry.
In the case of Excel they use what is called DDE for the purpose. That's why you see nothing on the command line.
文件名实际上并不总是作为参数传递。
您自己有一个与注册表中某些特定文件类型关联的程序列表。系统检查文件扩展名，然后启动与之关联的进程。但总是将其作为参数传递是不正确的。操作系统有自己的体系结构来从其程序集中调用程序。
