SHFILEOPSTRUCT problem

I am using this api to copy files from one location to another
However if the files already exist in the destination location I want the program to ask me if it is ok to overwrite the existing files
I have read all about the different flags used with this api but I can find nothing about overwrittihg files

can this be done


code
Dim fos As SHFILEOPSTRUCT
Dim sa(1 To 32) As Byte
Dim retval As Long

With fos

.hWnd = Form1.hWnd

.wFunc = FO_COPY

.pFrom = C:\test\*.* & vbNullChar & vbNullChar

.pTo = C:\temp & vbNullChar & vbNullChar

.fFlags = FOF_SIMPLEPROGRESS Or FOF_ALLOWUNDO

.fAnyOperationsAborted = 0
.hNameMappings = 0

End With

CopyMemory sa(1), fos, LenB(fos)
CopyMemory sa(19), sa(21), 12


retval = SHFileOperation(sa(1))


CopyMemory sa(21), sa(19), 12
CopyMemory fos, sa(1), Len(fos)

Thanks for your time

How about running code, before your copy operation, to check to see if the file exists? If it does, then before you call your copy operation, popup a message verifying the copy.
