Hello Experts

I have some code below which will search through the c:\ drive
it searches for the file contained in variable ( sSrchString )

what id like to do is have a text file   filenames.txt which contains 5 or more files
to search for

filenames.txt  could have any amount of different files e.g

firstfile.ini
secondfill.dll
thirdfile.exe
fourthfile.txt
fifthfile.jpg

id like my code to go through the filenames.txt file to search the c:\ drive for all names
contained in filenames.txt

This works....

I decided to write a different set of code in case you want to be consistant by using the FileSystemObject and TextStream to read the input file instead of the generic vb readfile stuff.


----------------------------------------

Dim fso As New FileSystemObject   ' Add microsoft scripting runtime reference
Dim fld As Folder
Const fsoForReading = 1

Private Sub Command1_Click()
   
    Dim nDirs As Long, nFiles As Long, lSize As Currency
    Dim sDir As String, sSrchString As String
   
    Dim strInputFileName As String
    Dim objTextStream As TextStream

   
    sDir = "c:\"
     
   
    strInputFileName = "C:\input.txt"
   
    Set objTextStream = fso.OpenTextFile(strInputFileName, fsoForReading)
   
    Do While Not objTextStream.AtEndOfStream
        sSrchString = objTextStream.ReadLine
   
        Label1.Caption = "Searching " & vbCrLf & UCase(sDir) & "..."
       
        lSize = FindFile(sDir, sSrchString, nDirs, nFiles)
       
        MsgBox Str(nFiles) & " files found in" & Str(nDirs) & " directories", vbInformation
        MsgBox "Total Size = " & lSize & " bytes"
   
    Loop
    Close #1
   
   

End Sub

Private Function FindFile(ByVal sFol As String, sFile As String, nDirs As Long, nFiles As Long) As Currency
   Dim tFld As Folder, tFil As File, FileName As String
   
   On Error GoTo Catch
   Set fld = fso.GetFolder(sFol)
   FileName = Dir(fso.BuildPath(fld.Path, sFile), vbNormal Or vbHidden Or vbSystem Or vbReadOnly)
   While Len(FileName) <> 0
      FindFile = FindFile + FileLen(fso.BuildPath(fld.Path, FileName))
      nFiles = nFiles + 1
      List1.AddItem fso.BuildPath(fld.Path, FileName)  ' Load ListBox
      FileName = Dir()  ' Get next file
      DoEvents
   Wend
   Label1 = "Searching " & vbCrLf & fld.Path & "..."
   nDirs = nDirs + 1
   If fld.SubFolders.Count > 0 Then
      For Each tFld In fld.SubFolders
         DoEvents
         FindFile = FindFile + FindFile(tFld.Path, sFile, nDirs, nFiles)
      Next
   End If
   Exit Function
Catch:  FileName = ""
       Resume Next
End Function

'--------------------------------------------------------------------------------------




The key part is:

    strInputFileName = "C:\input.txt"
   
    ' Open the new text stream
    Set objTextStream = fso.OpenTextFile(strInputFileName, fsoForReading)
   
    ' whiles its not the end of the file:
    Do While Not objTextStream.AtEndOfStream
        ' get the filename to find
        sSrchString = objTextStream.ReadLine

        '''''''''''''''''''''''' your code here ''''''''''''''''''''''''

    ' finished with the file, loop and start again
    Loop


good luck

oh, one more think.

strInputFileName = "C:\input.txt"


should have "C:\filenames.txt" or whatever the full path of the file that contains the list of files to search for.

Would there be a chance that instead of having to search all the drive again
with each new file in the "C:\input.txt"

it would rather do a search like

eg.

code starts search at the begining of c:\ drive

the first file it finds is   (  firstfilefound.exe  )

firstfilefound.exe  >>>>>  check if this file is in 1st line of "C:\input.txt"
if yes save path and filename to a variable for later processing

then with the same firstfilefound.exe on drive c:
firstfilefound.exe  >>>>>  check if this file is in 2nd line of "C:\input.txt"
if yes save path and filename to a variable for later processing

then with the same firstfilefound.exe on drive c:
firstfilefound.exe  >>>>>  check if this file is in 3rd line of "C:\input.txt"
if yes save path and filename to a variable for later processing

once all filenames in "C:\input.txt" has been searched it would move to
secondfilefound.exe on c:\drive  >>>>>  check if this file is in 1st line of "C:\input.txt"

etc etc etc

Basically i would like to search the c: drive in the quickest possible manner

the "C:\input.txt" will contain a lot of files names for processing later on

i figure this is a fast way to do it.

thankyou experts

oh, ok....

do this instead...


Dim fso As New FileSystemObject   ' Add microsoft scripting runtime reference
Dim fld As Folder
Const fsoForReading = 1

Private Sub Command1_Click()
   
    Dim nDirs As Long, nFiles As Long, lSize As Currency

    Set objTextStream = fso.OpenTextFile(strInputFileName, fsoForReading)
   
    Do While Not objTextStream.AtEndOfStream
        sSrchString = sSrchString & ";" & objTextStream.ReadLine
   
    Loop

        Label1.Caption = "Searching " & vbCrLf & UCase(sDir) & "..."
       
        lSize = FindFile(sDir, sSrchString, nDirs, nFiles)
       
        MsgBox Str(nFiles) & " files found in" & Str(nDirs) & " directories", vbInformation
        MsgBox "Total Size = " & lSize & " bytes"


End Sub

Private Function FindFile(ByVal sFol As String, sFile As String, nDirs As Long, nFiles As Long) As Currency
   Dim tFld As Folder, tFil As File, FileName As String
   
   On Error GoTo Catch
   Set fld = fso.GetFolder(sFol)
   FileName = Dir(fso.BuildPath(fld.Path, sFile), vbNormal Or vbHidden Or vbSystem Or vbReadOnly)
   While Len(FileName) <> 0
      FindFile = FindFile + FileLen(fso.BuildPath(fld.Path, FileName))
      nFiles = nFiles + 1
      List1.AddItem fso.BuildPath(fld.Path, FileName)  ' Load ListBox
      FileName = Dir()  ' Get next file
      DoEvents
   Wend
   Label1 = "Searching " & vbCrLf & fld.Path & "..."
   nDirs = nDirs + 1
   If fld.SubFolders.Count > 0 Then
      For Each tFld In fld.SubFolders
         DoEvents
         FindFile = FindFile + FindFile(tFld.Path, sFile, nDirs, nFiles)
      Next
   End If
   Exit Function
Catch:  FileName = ""
       Resume Next
End Function

'--------------------------------------------------------------------------------------

basically, seperating the filenames by ; is how you can find multiple files

Is this what you are after?

Seems to enumerate  the c:\  drive and also goes through the input.txt file
but does not seem to match anything

where can i implement:

if sSrchString =  files on hdd then
add to listbox
end if

thankyou expert

that last part should have read:

if sSrchString =  files on hdd then
add to path and filename to a listbox
end if

ill have a look at it tonight sometime, im pretty sure its right, but i didnt actually run the code. I know that windows find does use ; to seperate searches... i might have stuffed up the code somewhere.

Ill get back to u in about 4 hours... sorry for the delay soooo much work to do.

ok........

This searchs the filesystem only once, and finds all files specified in the input file:
------------------------------------

Dim fso As New FileSystemObject   ' Add microsoft scripting runtime reference
Dim fld As Folder
Const fsoForReading = 1

Private Sub Command1_Click()
   
    Dim nDirs As Long, nFiles As Long, lSize As Currency

    Dim strInputFileName As String
    Dim objTextStream As TextStream

    Dim i As Integer
   
    sDir = "c:\"
     
   
    strInputFileName = "C:\input.txt"
   
    Set objTextStream = fso.OpenTextFile(strInputFileName, fsoForReading)
   

    ReDim Preserve sSrchString(i)
    Do While Not objTextStream.AtEndOfStream
        i = UBound(sSrchString) + 1
        ReDim Preserve sSrchString(i)

End Sub

   Dim tFld As Folder, tFil As File, FileName As String
   
   On Error GoTo Catch
   Set fld = fso.GetFolder(sFol)
   For i = 1 To UBound(sFile)
        FileName = Dir(fso.BuildPath(fld.Path, sFile(i)), vbNormal Or vbHidden Or vbSystem Or vbReadOnly)
        While Len(FileName) <> 0
           FindFile = FindFile + FileLen(fso.BuildPath(fld.Path, FileName))
           nFiles = nFiles + 1
