با سلام
باید از چند تا API استفاده بشه :
با API زیر میتونین تمام درایو های منطقی موجود رو پیدا کنین (فلاپی،سی دی رام،فلش مموری،پارتیشنهای هارد و ...)
کد:
Private Declare Function GetLogicalDriveStrings Lib "kernel32" Alias "GetLogicalDriveStringsA" (ByVal nBufferLength As Long, ByVal lpBuffer As String) As Long
و با API زیر میتونین تشخیص بدین که نوع هر درایو چی هست
کد:
Private Declare Function GetDriveType Lib "kernel32" Alias "GetDriveTypeA" (ByVal nDrive As String) As Long
اینهم مثالش :
*= اول یه لیست باکس بذارین رو فرم .
کد:
Private Declare Function GetLogicalDriveStrings Lib "kernel32" Alias "GetLogicalDriveStringsA" (ByVal nBufferLength As Long, ByVal lpBuffer As String) As Long
Private Declare Function GetDriveType Lib "kernel32" Alias "GetDriveTypeA" (ByVal nDrive As String) As Long
Private Sub FindLogicalDrives()
Dim strSave As String
Dim Dr As String
strSave = String(255, Chr$(0))
ret& = GetLogicalDriveStrings(255, strSave)
For i = 1 To 100
If Left$(strSave, InStr(1, strSave, Chr$(0))) = Chr$(0) Then Exit For
Dr = Left$(strSave, InStr(1, strSave, Chr$(0)) - 1)
List1.AddItem Dr & " => " & GetType(GetDriveType(Dr))
strSave = Right$(strSave, Len(strSave) - InStr(1, strSave, Chr$(0)))
Next
End Sub
Private Function GetType(Dr As String) As String
Select Case Dr
Case 2
GetType = "Removable"
Case 3
GetType = "Drive Fixed"
Case Is = 4
GetType = "Remote"
Case Is = 5
GetType = "Cd-Rom"
Case Is = 6
GetType = "Ram disk"
Case Else
GetType = "Unrecognized"
End Select
End Function
Private Sub Form_Load()
FindLogicalDrives
End Sub
و برای جستجوی فایلها باید از این API ها استفاده بشه :
کد:
Private Declare Function FindFirstFile Lib "kernel32" Alias "FindFirstFileA" (ByVal lpFileName As String, lpFindFileData As WIN32_FIND_DATA) As Long
Private Declare Function FindNextFile Lib "kernel32" Alias "FindNextFileA" (ByVal hFindFile As Long, lpFindFileData As WIN32_FIND_DATA) As Long
Private Declare Function FindClose Lib "kernel32" (ByVal hFindFile As Long) As Long
اینم نمونه استفاده :
*=یه کامند یه لیست باکس و دو تا تکست باکس لازم داره که تو تکست اولی آدرس برای جستجو و تو دمی اسم فایل .
*2= برای جستجوی همه فایلها از * استفاده کنید .
کد:
Private Declare Function FindFirstFile Lib "kernel32" Alias "FindFirstFileA" (ByVal lpFileName As String, lpFindFileData As WIN32_FIND_DATA) As Long
Private Declare Function FindNextFile Lib "kernel32" Alias "FindNextFileA" (ByVal hFindFile As Long, lpFindFileData As WIN32_FIND_DATA) As Long
Private Declare Function GetFileAttributes Lib "kernel32" Alias "GetFileAttributesA" (ByVal lpFileName As String) As Long
Private Declare Function FindClose Lib "kernel32" (ByVal hFindFile As Long) As Long
Const MAX_PATH = 260
Const MAXDWORD = &HFFFF
Const INVALID_HANDLE_VALUE = -1
Const FILE_ATTRIBUTE_ARCHIVE = &H20
Const FILE_ATTRIBUTE_DIRECTORY = &H10
Const FILE_ATTRIBUTE_HIDDEN = &H2
Const FILE_ATTRIBUTE_NORMAL = &H80
Const FILE_ATTRIBUTE_READONLY = &H1
Const FILE_ATTRIBUTE_SYSTEM = &H4
Const FILE_ATTRIBUTE_TEMPORARY = &H100
Private Type FILETIME
dwLowDateTime As Long
dwHighDateTime As Long
End Type
Private Type WIN32_FIND_DATA
dwFileAttributes As Long
ftCreationTime As FILETIME
ftLastAccessTime As FILETIME
ftLastWriteTime As FILETIME
nFileSizeHigh As Long
nFileSizeLow As Long
dwReserved0 As Long
dwReserved1 As Long
cFileName As String * MAX_PATH
cAlternate As String * 14
End Type
Function StripNulls(OriginalStr As String) As String
If (InStr(OriginalStr, Chr(0)) > 0) Then
OriginalStr = Left(OriginalStr, InStr(OriginalStr, Chr(0)) - 1)
End If
StripNulls = OriginalStr
End Function
Function FindFilesAPI(path As String, SearchStr As String, FileCount As Integer, DirCount As Integer)
Dim FileName As String ' Walking filename variable...
Dim DirName As String ' SubDirectory Name
Dim dirNames() As String ' Buffer for directory name entries
Dim nDir As Integer ' Number of directories in this path
Dim i As Integer ' For-loop counter...
Dim hSearch As Long ' Search Handle
Dim WFD As WIN32_FIND_DATA
Dim Cont As Integer
If Right(path, 1) <> "\" Then path = path & "\"
' Search for subdirectories.
nDir = 0
ReDim dirNames(nDir)
Cont = True
hSearch = FindFirstFile(path & "*", WFD)
If hSearch <> INVALID_HANDLE_VALUE Then
Do While Cont
DirName = StripNulls(WFD.cFileName)
' Ignore the current and encompassing directories.
If (DirName <> ".") And (DirName <> "..") Then
' Check for directory with bitwise comparison.
If GetFileAttributes(path & DirName) And FILE_ATTRIBUTE_DIRECTORY Then
dirNames(nDir) = DirName
DirCount = DirCount + 1
nDir = nDir + 1
ReDim Preserve dirNames(nDir)
End If
End If
Cont = FindNextFile(hSearch, WFD) 'Get next subdirectory.
Loop
Cont = FindClose(hSearch)
End If
' Walk through this directory and sum file sizes.
hSearch = FindFirstFile(path & SearchStr, WFD)
Cont = True
If hSearch <> INVALID_HANDLE_VALUE Then
While Cont
FileName = StripNulls(WFD.cFileName)
If (FileName <> ".") And (FileName <> "..") Then
FindFilesAPI = FindFilesAPI + (WFD.nFileSizeHigh * MAXDWORD) + WFD.nFileSizeLow
FileCount = FileCount + 1
List1.AddItem path & FileName
End If
Cont = FindNextFile(hSearch, WFD) ' Get next file
Wend
Cont = FindClose(hSearch)
End If
' If there are sub-directories...
If nDir > 0 Then
' Recursively walk into them...
For i = 0 To nDir - 1
FindFilesAPI = FindFilesAPI + FindFilesAPI(path & dirNames(i) & "\", SearchStr, FileCount, DirCount)
Next i
End If
End Function
Sub Command1_Click()
Dim SearchPath As String, FindStr As String
Dim FileSize As Long
Dim NumFiles As Integer, NumDirs As Integer
Screen.MousePointer = vbHourglass
List1.Clear
SearchPath = Text1.Text
FindStr = Text2.Text
Screen.MousePointer = vbDefault
End Sub
حالا اگه میخواهین خرابکاری کنین که اصلا کار خوبی نیست زمانی که آدرس فایل میخواد به لیست باکس اضافه بشه بجاش دستور حذف فایل رو ارسال کنید .
