2、往word文档写入文字,参考
Dim app As New MSWord.Application
try
Dim fileName = "d:\test.doc"
Dim doc = app.Documents.Open(fileName)
app.ActiveWindow.Selection.WholeStory
app.ActiveWindow.Selection.MoveRight(Unit:=1, Count:=1)
app.ActiveWindow.Selection.TypeParagraph
app.ActiveWindow.Selection.TypeText(Text:="123456")
app.Visible = True
catch ex As exception
msgbox(ex.message)
app.Quit
finally
End try
