Line Input Statement diagram


Line Input #fileNum, variable

Parameters:

fileNum: Number of the file that contains the data that you want to read. The file must have been opened in advance with the Open statement using the key word INPUT.

variable: The name of the variable that stores the result.

使用 Line Input# 陳述式，您可以從開啟的檔案讀取字串，並將其寫入一個變數中。字串型變數的逐行讀取程序在遇到第一個斷行鍵 (Asc=13) 或斷行 (Asc=10) 時停止。結果字串中不包含行尾標記。

Example:


Sub ExampleWorkWithAFile
Dim iNumber As Integer
Dim sLine As String
Dim aFile As String
Dim sMsg As String
    aFile = "c:\data.txt"
    iNumber = Freefile
    Open aFile For Output As #iNumber
    Print #iNumber, "This is a line of text"
    Print #iNumber, "This is another line of text"
    Close #iNumber
    iNumber = Freefile
    Open aFile For Input As iNumber
    While Not eof(iNumber)
        Line Input #iNumber, sLine
        If sLine <>"" Then
            sMsg = sMsg & sLine & chr(13)
        End If
    Wend
    Close #iNumber
    MsgBox sMsg
End Sub
