我在实践过程中碰到下面这个问题:点击按钮后找开我设定的记事本文件.试了很多次都不成功.方法1\ dim retval as long
retval = shell ("start d:\评测.txt") 提示说找不到这个文件方法2\ Shell "NotePad.EXE d:\评测.txt", vbNormalfucus
能运行,但运行后这个文件并没有打开 方法3\ RichTextBox1.LoadFile "f:\d.txt", rtfText
提示说找不到对象,
我是VB的一只菜鸟,请大家帮忙!多谢!!

'说明
' 查找与指定文件关联在一起的程序的文件名
'返回值
'Long,非零表示成功,零表示失败。会设置GetLastError
'参数表
'参数 类型及说明
'hwnd Long,指定一个窗口的句柄,有时候,windows程序有必要在创建自己的主窗口前显示一个消息框
'lpOperation String,指定字串“open”来打开lpFlie文档,或指定“Print”来打印它
'lpFile String,想用关联程序打印或打开一个程序名或文件名
'lpParameters String,如lpszFlie是可执行文件,则这个字串包含传递给执行程序的参数
