将txt文件中的内容下载到变量 [英] Downloading content from txt file to a variable

问题描述

我做了一个计数器，当你按下按钮作为 VBScript 中的动作时它会起作用.

I made a counter that works when you press the button as the action in VBScript.

我的代码:

  Licznik_ID = Licznik_ID + 1

    Dim Stuff, myFSO, WriteStuff, dateStamp

    Stuff = "Whatever you want written"

    Set myFSO = CreateObject("Scripting.FileSystemObject")
    Set WriteStuff = myFSO.OpenTextFile("c:\tmp\yourtextfile.txt", 2, True)
    WriteStuff.WriteLine(Licznik_ID)
    WriteStuff.Close
    SET WriteStuff = NOTHING
    SET myFSO = NOTHING

名为Licznik_ID"的计数器变量箭头所指.

the counter variable named "Licznik_ID" indicated by the arrow.

写入文件c:\tmp\yourtextfile.txt"它运作良好.每次数字增加一并被替换并存储在txt文件中.

It is written to the file "c:\tmp\yourtextfile.txt" And it works well. For each time the number increases by one and is replaced and stored in the txt file.

文件包含数字1，txt文件中增加出现数字2等等......

The file contains the number 1 and the increase in the txt file appears the number 2 and so on ...

现在如何将与文件c:\tmp\yourtextfile.txt"一起存储的数据下载回变量以使用它，以便在您启动 NiceForm 或按钮时已将 txt 文件的内容加载到一个变量?

How now download the data stored with the file "c: \tmp\yourtextfile.txt" back to the variable to use it in such a way that when you start NiceForm or button has been loaded with the contents of txt file into a variable?

推荐答案

Set myFSO = CreateObject("Scripting.FileSystemObject")
Licznik_ID = myFSO.OpenTextFile("C:\tmp\yourtextfile.txt").ReadAll
Licznik_ID = Licznik_ID + 1
myFSO.OpenTextFile("C:\tmp\yourtextfile.txt",2,True).Write(Licznik_ID)

FSO 有时处理文件模式的方式有点奇怪.

FSO is kinda weird the way it does its file modes sometimes.

如果您想允许它在不存在的情况下创建没有错误的文件，请将第 2 行替换为:

edit: If you want to allow this to create the file without errors if it doesn't exist, replace line 2 with this:

If myFSO.FileExists("C:\tmp\yourtextfile.txt") Then 
    Licznik_ID = myFSO.OpenTextFile("C:\tmp\yourtextfile.txt").ReadAll
End If 

如果文件不存在，Licznik_ID 将为 Empty.Empty + 1 = 1 在 vbscript 中.

If the file doesn't exist, Licznik_ID will be Empty. Empty + 1 = 1 in vbscript.
