[RESOLVED] Copying one folder and overwriting the other

How can I make code that will copy a folder with other folders and files in it, and overwrite the other one. For example if I had two folders, both named "hello". And I want to overwrite the folder named hello in "C:\Program Files\Myapp" with the folder called "hello" in the app.path? How can I do this through code?

VB Code:

Option Explicit
'Add a command button
Private Type SHFILEOPSTRUCT
    hWnd As Long
    wFunc As Long
    pFrom As String
    pTo As String
    fFlags As Integer
    fAborted As Boolean
    hNameMaps As Long
    sProgress As String
End Type
 
Private Const FO_MOVE As Long = &H1
Private Const FO_COPY As Long = &H2
Private Const FO_DELETE = &H3
Private Const FO_RENAME As Long = &H4
 
Private Const FOF_ALLOWUNDO = &H40
Private Const FOF_SIMPLEPROGRESS As Long = &H100
 
Private Declare Function SHFileOperation Lib "shell32.dll" Alias "SHFileOperationA" (lpFileOp As SHFILEOPSTRUCT) As Long
 
Private Sub Command1_Click()
    Dim SHFileOp As SHFILEOPSTRUCT
    With SHFileOp
        .wFunc = FO_COPY
        .pFrom = "D:\app" 'Select a folder and all its subdirectories/files
        .pTo = "D:\TestMove" 'You can also rename the file if you want of leave it the same
        .fFlags = FOF_ALLOWUNDO Or FOF_SIMPLEPROGRESS
    End With
    'perform file operation
    SHFileOperation SHFileOp
    MsgBox "The folder 'D:\app' has been copied to 'D:\TestMove'!", vbInformation + vbOKOnly, App.Title '
End Sub

:)

How can I hide that alert, it works and all, but it doesn't overwrite the folder without showing a message.

Here are some more flags that can help you customise it.

VB Code:

Private Const FOF_NOCONFIRMATION As Long = &H10
Private Const FOF_NOCONFIRMMKDIR As Long = &H200
Private Const FOF_NOERRORUI As Long = &H400
Private Const FOF_RENAMEONCOLLISION As Long = &H8
Private Const FOF_SILENT As Long = &H4
Private Const FOF_WANTNUKEWARNING As Long = &H4000

VB Code:

Option Explicit
'Add a command button
Private Type SHFILEOPSTRUCT
    hWnd As Long
    wFunc As Long
    pFrom As String
    pTo As String
    fFlags As Integer
    fAborted As Boolean
    hNameMaps As Long
    sProgress As String
End Type
 
Private Const FO_MOVE As Long = &H1
Private Const FO_COPY As Long = &H2
Private Const FO_DELETE = &H3
Private Const FO_RENAME As Long = &H4
 
Private Const FOF_ALLOWUNDO = &H40
Private Const FOF_SIMPLEPROGRESS As Long = &H100
Private Const FOF_NOCONFIRMATION As Long = &H10
Private Const FOF_NOCONFIRMMKDIR As Long = &H200
Private Const FOF_NOERRORUI As Long = &H400
Private Const FOF_RENAMEONCOLLISION As Long = &H8
Private Const FOF_SILENT As Long = &H4
Private Const FOF_WANTNUKEWARNING As Long = &H4000
 
Private Declare Function SHFileOperation Lib "shell32.dll" Alias "SHFileOperationA" (lpFileOp As SHFILEOPSTRUCT) As Long
 
Private Sub Form_Load()
Dim SHFileOp As SHFILEOPSTRUCT
    With SHFileOp
        .wFunc = FO_COPY
        .pFrom = "C:\pb" 'Select a folder and all its subdirectories/files
        .pTo = "C:\Program Files\EA GAMES" 'You can also rename the file if you want of leave it the same
        .fFlags = FOF_NOCONFIRMATION
    End With
    'perform file operation
    SHFileOperation SHFileOp
End Sub

I did that and it didn't overwrite the folder, it just put my contents from the C:\pb folder into the other one.

Nevermind I figured out what was wrong.

Here are the explainations of the flags that are relevant.

FOF_NOCONFIRMATION
Respond with "Yes to All" for any dialog box that is displayed.
FOF_NOCONFIRMMKDIR
Do not confirm the creation of a new directory if the operation requires one to be created.
FOF_RENAMEONCOLLISION
Give the file being operated on a new name in a move, copy, or rename operation if a file with the target name already exists.

Edit: Too late but glad its solved. :)
