Question

vb 文件搜索

想让程序 能自动 在某个指定的目录里搜索 一些指定名字的文件
例如 在E:\里 搜索叫1.txt的文件 而且 要搜索子目录
整个E:\可能有多个 1.txt 把他们 的 路径都 列出来...
有办法吗?
修改一下..
只需要 搜索当前的文件夹里有没有这个文件
例如 E:\ 有 123 124 125 3个文件夹
搜索这3个里面有没有 1.txt 不需要 再往下级目录搜索

新建一个标准EXE工程，加载一个ListBox；两个CommandButton；两个TextBox；及一个PictureBox控件，然后贴上以下代码：

Option Explicit
Private Const MAX_PATH As Long = 260
Private Const INVALID_HANDLE_VALUE As Long = -1
Private Const DT_NOPREFIX As Long = 2048
Private Const DT_PATH_ELLIPSIS As Long = &H4000
Private Const DT_WORDBREAK As Long = &H10
Private Type RECT
Left As Long
Top As Long
Right As Long
Bottom As Long
End Type
Private Type SYSTEMTIME
wYear As Integer
wMonth As Integer
wDayOfWeek As Integer
wDay As Integer
wHour As Integer
wMinute As Integer
wSecond As Integer
wMilliseconds As Integer
End Type
Private Type FILETIME
dwLowDateTime As Long
dwHighDateTime As Long
End Type
Private Type WIN32_FIND_DATA

If Trim(Text2.Text) = "" Then Exit Sub
m_DestinationFile = Trim(Text2.Text) '要拷贝的目标驱动器/目录

m_DestinationFile = m_DestinationFile & "\"
End If

m_lFilesFound = 0
v = GetDriveType(m_DestinationFile)
Select Case v
Case 0 '不能识别的驱动器

Private Function SearchFiles(ByRef sFolder As String) As Long

End Function

Private Sub UpdateStatus(ByRef sStatus As String)
Dim uRect As RECT

uRect.Bottom = Picture1.Height - 1
DrawText Picture1.hDC, sStatus, -1, uRect, DT_PATH_ELLIPSIS Or DT_NOPREFIX Or DT_WORDBREAK
End If
End Sub

另外补充一下：
# 由于只是例子，只在Form模块下编写，正确的写法最好是建一个模块把API、常量及函数过程定义在模块中。

# 利用以上的遍历方法，还可以根据数据类型WIN32_FIND_DATA 的 dwFileAttributes、ftCreationTime、ftLastAccessTime、ftLastWriteTime 各元素来扩充文件查询功能（按文件属性、创建日期、最后修改日期、最后访问日期等不同条件的搜索）。

呵呵，代码是长了点，但这是高级高效率代码，您看不明白这不是您的错，这也证明了百度里并不是没有高手，而是你太低了！

用批处理(bat)太弱智了俺写不出手，就直接用cmd 随便搞搞吧：

Private Sub Command1_Click()
Dim mSource As String '源路径
Dim mDestination As String '目标路径

mSource = Trim(Text1.Text)
If mSource = "" Then Exit Sub
If Right(mSource, 1) <> "\" Then mSource = mSource & "\"
mSource = mSource & "*.txt"

mDestination = Trim(Text2.Text)
If mDestination = "" Then Exit Sub
If Right(mDestination, 1) <> "\" Then mDestination = mDestination & "\"

Shell "cmd /c xcopy " & mSource & " /s/y " & mDestination, vbNormalFocus

End Sub

Answer 2

f1="e:\123\1.txt"
if dir(f,vbReadOnly + vbHidden + vbNormal + vbArchive)<>"" then
print f & "不存在"
else
print f & "存在"
end if
