Option Explicit
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

Private Sub Command1_Click()

上面的代码打开不了文档
如果要打开word文档，需要安装Imports Microsoft.Office.Interop

Imports Microsoft.Office.Interop

Module Module1
    Sub Main()
        ' 创建Word应用程序实例
        Dim wordApp As New Word.Application()
        ' 设置为可见
        wordApp.Visible = True

        ' 打开指定的Word文档
        Dim doc As Word.Document = wordApp.Documents.Open("C:\\Users\\zhour\\Documents\\点击.docx")

        ' 在此处添加代码以处理文档


    End Sub


End Module
