我想在(C:驱动器位置)中的本地计算机中打开日志文件(test.log) VB脚本函数说" LogGen" 。这个日志文件应该在点击按钮,VB脚本函数" LogGen"应该被调用并执行。
<input type="button" name="Log" id="Start" value=" Login " onclick="LogGen">
我是VB脚本的新手。有人可以建议我使用Vb脚本函数的一些示例代码来获取本地目录中的日志文件吗?
新问题代码
Sub LogOpen()
Const ForReading = 1, ForWriting = 2, ForAppending = 8
Const TristateUseDefault = -2, TristateTrue = -1, TristateFalse = 0
Dim fso, MyFile, FileName, TextLine
Set fso = CreateObject("Scripting.FileSystemObject")
' Open the file for output.
FileName = "c:\\testfile.txt"
Set MyFile = fso.OpenTextFile(FileName, ForWriting, True, TristateTrue)
' Open the file for input.
Set MyFile = fso.OpenTextFile(FileName, ForReading)
' Read from the file and display the results.
Do While MyFile.AtEndOfStream <> True
TextLine = MyFile.ReadLine
Document.Write TextLine & "<br />"
Loop
'MyFile.Close
End Sub
我做了如上所示的那个,并在一个名为&#34; Log&#34;的按钮事件中调用了这个子程序。但它不起作用。 出现yz类型的空白屏幕,它占据整个窗口,然后必须关闭应用程序。 请问你可以建议错误的位置。我希望点击“日志”按钮时弹出C目录中的日志文件,但这不会发生。
<input type="button" name="Log" value="Log" onclick="LogOpen"><br/>

您可以采取以下措施:
Const ForReading = 1
set fs = CreateObject("Scripting.FileSystemObject")
set objTextFile = fs.OpenTextFile(filePathto/test.log, ForReading)
