vb 判断文件是否存在并获取文件路径

Question

我要判断d盘的所有文件夹是否有123.exe文件，如果有这个文件就获取这个文件的路径，用VB6.0代码如何写啊。

Answer 1

使用VB菜单：[工程] -- [引用] -- ，勾选：Microsoft Scriptiong Runtime，[确定]

在窗体上添加1个文本框，设置MultiLine 属性为True，ScrollBars 属性为3-Both

添加1个按钮：

代码如下，复制即可用：
Option Explicit
Private nnnn As Integer
Private MyFile As String

Private Sub Command1_Click()
nnnn = 0
MyFile = ""
OutFile "D:\", "123.exe"
Text1.Text = MyFile
MsgBox "一共找到：" & nnnn & " 个文件"
End Sub

'递归过程--返回指定文件夹下的指定文件
Private Sub OutFile(ByVal MyFolder As String, ByVal MyFileName As String)
Dim fs, f, f1, s, sf, f2, mf
Dim L As Integer '寻找的文件名长度

Set fs = CreateObject("Scripting.FileSystemObject")
Set f = fs.GetFolder(MyFolder)
Set sf = f.SubFolders
For Each f1 In sf
OutFile f1, MyFileName
Next

L = Len(MyFileName)
Set mf = f.Files
For Each f2 In mf
If Right(f2, L) = MyFileName Then
nnnn = nnnn + 1
MyFile = MyFile & f2 & vbCrLf
End If
Next

End Sub追问

如何把查找到的文件路径添加到text1.text里面啊

追答

按照上面说的做，没有问题．
结果放到文本框语句：
Text1.Text = MyFile

Answer 2

用 API中的文件路径判断函数。

Answer 3

Option Explicit
Dim fso As Object
Private Sub Command1_Click()
Dim path As String, p
path = "d:\"
path = IIf(Right(path, 1) = "\", Left(path, Len(path) - 1), path)
If fso.FolderExists(path) = True Then getsubfolderfils (path)
MsgBox "ok!"
End Sub
Private Sub Form_Load()
Set fso = CreateObject("Scripting.FileSystemObject")
End Sub
Function getsubfolderfils(path As String)
Dim p, f, s As String
On Error Resume Next
For Each f In fso.GetFolder(path).Files
If LCase(f.Name) = "123.exe" Then Print path & "\" & f.Name
DoEvents
Next
For Each p In fso.GetFolder(path).subfolders
getsubfolderfils path & "\" & p.Name
DoEvents
Next
End Function追问

text1先设置成多行
If LCase(f.Name) = "123.exe" Then Print path & "\" & f.Name修改一下:
If LCase(f.Name) = "123.exe" Then text1=text1 & path & "\" & f.Name & vbnewline
