[RESOLVED] Need help to modify copy file function

Hi all,

Here is the code I have to copy the file:

VB Code:

Option Explicit
 
Private Type SHFILEOPSTRUCT
    hwnd As Long
    wFunc As Long
    pFrom As String
    pTo As String
    fFlags As Integer
    fAnyOperationsAborted As Long
    hNameMappings As Long
    lpszProgressTitle As String
End Type
 
Private Declare Function SHFileOperation Lib "shell32.dll" Alias "SHFileOperationA" (lpFileOp As SHFILEOPSTRUCT) As Long
 
Private Const FOF_ALLOWUNDO = &H40
Private Const FOF_NOCONFIRMATION = &H10
Private Const FO_COPY = &H2
 
Public Function ShellFileCopy(src As String, dest As String, Optional NoConfirm As Boolean = False) As Boolean
'PURPOSE: COPY FILES VIA SHELL API
'THIS DISPLAYS THE COPY PROGRESS DIALOG BOX
'PARAMETERS: src: Source File (FullPath)
'dest: Destination File (FullPath)
'NoConfirm (Optional): If set to true, no confirmation box is displayed when overwriting
'existing files, and no copy progress dialog box is displayed.
 
'Returns (True if Successful, false otherwise)
 
'EXAMPLE:
'dim bSuccess as boolean
'bSuccess = ShellFileCopy ("C:\MyFile.txt", "D:\MyFile.txt")
'bSuccess = ShellFileCopy ("C:\MyFile.txt", "D:\MyFile.txt", False)
 
    Dim WinType_SFO As SHFILEOPSTRUCT
    Dim lRet As Long
    Dim lflags As Long
 
    lflags = FOF_ALLOWUNDO
    If NoConfirm Then lflags = lflags & FOF_NOCONFIRMATION
    With WinType_SFO
        .wFunc = FO_COPY
        .pFrom = src
        .pTo = dest
        .fFlags = lflags
    End With
 
    lRet = SHFileOperation(WinType_SFO)
    ShellFileCopy = (lRet = 0)
End Function
 
Private Sub Form_Load()
Dim bsuccess As Boolean
bsuccess = ShellFileCopy("C:\Temp\Excel[1].zip", "C:\Temp\Excel[2].zip", False)
End Sub

What I want to do is to modify this function to copy the file with animated progress and overwrite the existing file by default.

Thanks,

Kanna.

Just OR these two flags.

VB Code:

Private Const FOF_NOCONFIRMMKDIR As Long = &H200 'For folder copies with sub directories.
Private Const FOF_SIMPLEPROGRESS As Long = &H100 'Animated progress dialog

not sure if it helps you any, but it may be of interest.

copyfile win32api function:

VB Code:

Public Declare Function CopyFile Lib "kernel32" Alias "CopyFileA" (ByVal lpExistingFileName As String, ByVal lpNewFileName As String, ByVal bFailIfExists As Long) As Long

use:

VB Code:

value& = 1
c0py& = CopyFile("C:\Junk(1).txt","C:\Junk(2).txt",value&)

here value& is defined as true(non zero), and will not overwrite an existing file. if defined as 0, it will. c0py& will return zero on failure, nonzero on success, and sets GetLastError api. while it doesn't provide animated progress, it is very quick.

Hi Rob,

I can't get you. where I have to change in my code?

Hi ghettohacker,

I have your function already. i want to show the animation progress at the same time i don't like to ask the user to replace the existing file.

thanks,

Kanna

The APIs we are using are the same ones that Windows uses when it displays the file copy progress dialog.

Try adding the costs like so.

VB Code:

.fFlags = lflags OR FOF_SIMPLEPROGRESS OR FOF_NOCONFIRMMKDIR 'If your copying folders.
'Or another option...
.fFlags = lflags OR FOF_SIMPLEPROGRESS 'For only showing the progressbar dialog.
