File Manipulation With Progress Bar (Move, Copy, Delete, Read, Write, etc)

[vbman213]

Basically lets say my application needs to read a file or it needs to copy files around, move them etc... How can I link this with a progress bar to graphically display the "progress" of the operation?

Get the file size of the file using the FileLen() command. Then set the max length of the progress bar to the FileLen() file size. As the file is moved or copied adjust the progress bar accordingly.

Another option you have to use an Avi file while an operation is going on, that would be much simplier that using progress bar for those tasks...

Or that there is already a method of showing an animation while a file copy is in progress...

'Module:
Option Explicit 

Private Type SHFILEOPSTRUCT
    hWnd As Long
    wFunc As Long
    pFrom As String
    pTo As String
    fFlags As Integer
    fAnyOperationsAborted As Boolean
    hNameMappings As Long
    lpszProgressTitle As String
End Type

Declare Function SHFileOperation Lib "shell32.dll" Alias "SHFileOperationA" (lpFileOp As SHFILEOPSTRUCT) As Long

Private Const FO_COPY = &H2
Private Const FOF_ALLOWUNDO = &H40

Public Sub SHCopyFile(ByVal from_file As String, ByVal to_file As String)
Dim sh_op As SHFILEOPSTRUCT

    With sh_op
        .hWnd = 0
        .wFunc = FO_COPY
        .pFrom = from_file & vbNullChar & vbNullChar
        .pTo = to_file & vbNullChar & vbNullChar
        .fFlags = FOF_ALLOWUNDO
    End With

    SHFileOperation sh_op
End Sub

'Form
Private Sub Command1_Click()
'the following line will copy the file "d:\file.zip" to "d:\temp\file2.zip"
    SHCopyFile "c:\dee-u.zip", "d:\dee-u.zip"
End Sub
