vb问题：希望可以给代码

       先新建一个模块，设备设备里面添加API声明

       Option Explicit

       Declare Function MoveWindow Lib "user" (ByVal hwnd As Long,维修维修 ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal bRepaint As Long) As Long

       Declare Function SendMessage Lib "user" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

       Public Const LB_INITSTORAGE = &H1A8

       Public Const LB_ADDSTRING = &H

       Public Const WM_SETREDRAW = &HB

       Public Const WM_VSCROLL = &H

       Public Const SB_BOTTOM = 7

       Declare Function GetLogicalDrives Lib "kernel" () As Long

       Declare Function FindFirstFile Lib "kernel" Alias "FindFirstFileA" (ByVal lpFileName As String, lpFindFileData As WIN_FIND_DATA) As Long

       Public Const INVALID_HANDLE_VALUE = -1

       Declare Function FindNextFile Lib "kernel" Alias "FindNextFileA" (ByVal hFindFile As Long, lpFindFileData As WIN_FIND_DATA) As Long

       Declare Function FindClose Lib "kernel" (ByVal hFindFile As Long) As Long

       Type FILETIME

       dwLowDateTime As Long

       dwHighDateTime As Long

       End Type

       Public Const MaxLFNPath =

       Type WIN_FIND_DATA

       dwFileAttributes As Long

       ftCreationTime As FILETIME

       ftLastAccessTime As FILETIME

       ftLastWriteTime As FILETIME

       dwReserved0 As Long

       dwReserved1 As Long

       cFileName As String * MaxLFNPath

       cShortFileName As String *

       End Type

       然后在窗体上制作2个菜单，放置一个ListBox和一个PictureBox

       完整代码如下：

       程序运行时就能够通过输入文件名而进行模糊查找了
