Hello Peter,
From your post, my understanding on this issue is: you wonder how tosynchronize a document in server to its client with VB FileCopy function.
If I'm off base, please feel free to let me know.
Generally speaking, VB function FileCopy fails and pop out "Permission
denied" exception when we attempt to copy a file that is opened or when the
destination file cannot be overwritten. Please check if the document in the
server is opened, and if the destination in client can be overwritten.
If the file in the server is opened for a short time, in the client, we
could loop to check if the file is locked:
On Error Resume Next
Dim errNum as Integer
errNum = 1
While errNum > 0
FileCopy "server file", "client file"
errNum = Err.Number
Err.Clear
Wend
As long as the file is closed, the loop will stop and the file will be
copied.
Another approach is to use FileSystemObject
(http://msdn2.microsoft.com/en-us/library/2z9ffy99.aspx) , which can copy a
locked file:
Set fs = CreateObject("Scripting.FileSystemObject")
fs.copyfile "server file", "client file"
It copies the last save of the file.
Please have a try and let me know the result.
if you have any other concerns, or need anything else, please feel free to
let me know.
Sincerely,
Jialiang Ge (jialge@xxxxxxxxxxxxxxxxxxxx, remove 'online.')
