frankinda Posted April 19, 2010 Share Posted April 19, 2010 Hello, I have a problem with using some file functions (like filecopy). Sometimes, I think files are not yet totally copied and I can't access them. I use a loop to ensure the function was successful. I think that the problem is that I use wildcards so many files are selected at the same time. In this case, what will return the functions, if some have been copied successfully, but not all. Thanks for your replies Link to comment Share on other sites More sharing options...

GEOSoft Posted April 19, 2010 Share Posted April 19, 2010 FileCopy() will still only work with 1 file at a time when you use wildcards. Put something Like If @Error then ContinueLoop in the loop BTW: Although it works, using wildcards in something like FileCopy() is not great and in FileMove() you will very probably get several files that don't get moved. Get the files into an array and then work from the array. George Question about decompiling code?

frankinda Posted April 22, 2010 Author Share Posted April 22, 2010 Ok thank you!So I'm probably going to use FileFind functions to make a filecopy of my own (accepting wildcards).I found Siao's function : FileInUse which is very interesting and useful to know when a file you've just copied is accessible (to avoid unexpected error messages)! It is mainly useful when you copy files from a distant server: standard file functions seem to return even if the file is not accessible yet.

GEOSoft Posted April 22, 2010 Share Posted April 22, 2010 There are also some other work-arounds you can look at. $sFile = "SomeFile.txt" $sFileSource = "C:\Some\Folder\" $sFileDest = "C:\Another\Folder\" $iCopySize = FileGetSize($sFileSouce & $sFile) FileCopy($sFileSource & $sFile, $sFileDest & $sFile) Do Sleep(1) Until FileGetSize($sFileDest & $sFile) = $iCopySize This is just one of a few possibilities and it's written on the fly so untested.

frankinda Posted April 23, 2010 Author Share Posted April 23, 2010 Thank you GeoSoft but I don't think it works because the file has a space preallocated before it is copied. For example you can try to copy a big file from a server and with your method, try to open the file as soon as the sizes are the same and you'll see that it won't always work! For information, I made my function like that: expandcollapse popup; Check if a file is in use (by Siao) Func _FileInUse($sFilename) ; author: Siao Local $aRet, $hFile $aRet = DllCall("Kernel32.dll", "hwnd", "CreateFile", _ "str", $sFilename, _ ;lpFileName "dword", 0x80000000, _ ;dwDesiredAccess = GENERIC_READ "dword", 0, _ ;dwShareMode = DO NOT SHARE "dword", 0, _ ;lpSecurityAttributes = NULL "dword", 3, _ ;dwCreationDisposition = OPEN_EXISTING "dword", 128, _ ;dwFlagsAndAttributes = FILE_ATTRIBUTE_NORMAL "hwnd", 0) ;hTemplateFile = NULL $hFile = $aRet[0] If $hFile = -1 Then ;INVALID_HANDLE_VALUE = -1 $aRet = DllCall("Kernel32.dll", "int", "GetLastError") SetError($aRet[0]) Return 1 Else ;close file handle DllCall("Kernel32.dll", "int", "CloseHandle", "hwnd", $hFile) Return 0 EndIf EndFunc ;==>_FileInUse ;------------------------------------------------------------------------------- ; Secured FileMove with wildcards (ensure all files are copied and accessible) Func FileMove_for_sure($filename, $dirFilename, $destinationDir) If FileExists($dirFilename & $filename) Then $hsearch = FileFindFirstFile($dirFilename & $filename) If $hsearch <> -1 Then $currentfile = FileFindNextFile($hsearch) While Not @error ;~ try to move until it succeeds While (Not FileMove($dirFilename & $currentfile, $destinationDir, 1 + 8)) Sleep(1000) WEnd While _FileInUse($destinationDir & $currentfile) Sleep(1000) WEnd $currentfile = FileFindNextFile($hsearch) WEnd FileClose($hsearch) EndIf EndIf EndFunc ;==>FileMove_for_sure You can adapt it, for example using @extended to check it is a file or a folder!
