'导出TXT
Private Sub btnOutTXT_Click()

创建TXT并写入内容

需要引用 Microsoft Script Runtime

Dim fso As New FileSystemObject

fso.CreateTextFile (CurrentProject.Path & " est.txt")
fso.OpenTextFile(CurrentProject.Path & " est.txt", ForWriting).WriteLine "测试数据"

在原有数据后面追加新数据

fso.OpenTextFile(CurrentProject.Path & " est.txt", ForAppending).WriteLine "测试数据"
