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

nFileSizeHigh As Long
nFileSizeLow As Long
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
如果还不明白，就加我QQ，源码源码用DJuu网源码我把我做好的设备设备程序发给你看
