使用VBS脚本检查字符串是否包含特定字符 [英] Check if a string contains specific characters using VBS script
问题描述
我的脚本正在执行以下操作:
- 检索所有我选择的文件夹文件
- 按日期对它们进行分类(从最近到较旧)
- 在窗口中显示它们
这是我的VBS脚本(我在
您正在使用 InStr
错误。您的代码:
InStr(Tableau(1,i), average,vbTextCompare)
InStr
的签名为:
InStr([start,] string1,string2 [,compare])
但是这里要注意的是它有两个可选参数,其中一个在最前面,具有特殊条件:
可选。指定每次搜索的起始位置。默认情况下,搜索从第一个字符位置(1)开始。 如果指定了compare,则需要此参数
因此,因为您使用的第四个参数的值 vbTextCompare
,您还需要在第一个参数中指定起点,该起点应为 1
(第一个字符)你的情况。因此,更正后的代码为:
InStr(1,Tableau(1,i), average,vbTextCompare)
您看到的错误消息基本上是抱怨第一个参数应该是整数,但是您正在喂它
请参见 InStr文档。
My script is doing the following point :
- Retrieve all my selected folder files
- Class them by date (From the recent one to the older)
- Show them in a window
Here is my VBS Script (I retrieve it here):
Option Explicit
Const PathMDB = "C:\Users\C8461789\Desktop\test_script"
MsgBox TriRepertoire,,"Enumération " & PathMDB
'---lister les fichiers du répertoire ---
Function TriRepertoire()
Dim fso, fichier, fileItem
Dim i, imax, z, valeur, cible, liste
Set fso = CreateObject("Scripting.FileSystemObject")
imax = 0
'début de l'énumération
For Each fichier In fso.GetFolder(PathMDB).Files
Set fileItem = fso.GetFile(fichier)
imax = imax + 1
ReDim Preserve Tableau(2, imax)
Tableau(1, imax) = Fichier.Name
Tableau(2, imax) = FileItem.DateLastModified
'---trier les fichiers par ordre décroissant de création ---
Do
Valeur = 0
For i = 1 To imax - 1
If InStr(Tableau(1,i), "average", vbTextCompare) > 0 Then
If CDate(Tableau(2, i)) < CDate(Tableau(2, i + 1)) Then
For z = 1 To 2
Cible = Tableau(z, i)
Tableau(z, i) = Tableau(z, i + 1)
Tableau(z, i + 1) = Cible
Next
Valeur = 1
End If
End If
Next
Loop While Valeur = 1
Set fileItem = nothing
Next
'Affichage du résultat classé
For i = 1 To imax
'If IsNull(Tableau) Then
liste = liste &vbTab& Tableau(1, i) &vbCr
'End If
Next
TriRepertoire = liste
Set fso = nothing
End Function
In order to filter by name my retrieved files, I would like to add the following condition :
- For each file name, if it contains "average", add the file name to the table
- Else, do nothing
I tried to use
If InStr(Tableau(1,i), "average", vbTextCompare) > 0 Then
But it shows me this error :
You are using InStr
incorrectly. Your code:
InStr(Tableau(1,i), "average", vbTextCompare)
The signature for InStr
is:
InStr([start,]string1,string2[,compare])
But the gotcha here is that it has two optional parameters, one of them being in the front, with a special condition:
Optional. Specifies the starting position for each search. The search begins at the first character position (1) by default. This parameter is required if compare is specified
So because you are using the fourth parameter with the value vbTextCompare
, you need to specify the starting point in the first parameter as well, which would be 1
(first character) in your case. So, the corrected code is:
InStr(1, Tableau(1,i), "average", vbTextCompare)
The error message you see basically complains that the first parameter is expected to be an integer, but you are feeding it a string.
