What Does I/o Error 103 Mean
Error 103 with this code? up vote 10 down vote favorite 4 In several of my apps I have code similar to the following: if ForceDirectories(ExtractFilePath(lLogName)) then begin AssignFile(lLog, lLogName); try if FileExists(lLogName) then Append(lLog) else Rewrite(lLog); Writeln(lLog, lLogLine); finally {$I-}CloseFile(lLog);{$I+} end; end; In one application, the first time I try to execute this I consistently get an I/O Error 103 exception on the line with the

Append statement (the file does exist prior to calling this). All subsequent attempts at the operation will work fine however - until I restart the app. All the docs I found about this error so far indicated that this would either be caused by calling CloseFile without prior Reset or Rewrite (Append typically isn't mentioned) or if the file was in use by another process. As the exception occurs before the call to CloseFile it obviously couldn't be the former. I already tried inserting a Reset right after the AssignFile for good measure but then I get the exception on that line. There is also no other application overtly accessing that file. I say "overtly" because I do have a slight suspicion that anti-virus (TrendMicro in my case) might be the cuplrit here (so maybe the file is in use). If that was indeed the problem, what would be the best way around it? Hard-coding an automatic retry does not really feel like a clean solution to me... Another case where I sometimes get the 103 error is this code, which I use to create an empty file (or more often to empty an existing file): AssignFile(lFile, AFileName); try Rewrite(l

= class(Exception); C++ class EInOutError : public Exception; File SysUtils Description EInOutError is raised when an file input/output error occurs, provided I/O checking is enabled. Note: In Delphi code, use the $I+ directive to enable I/O checking. http://docs.embarcadero.com/products/rad_studio/delphiAndcpp2009/HelpUpdate2/EN/html/delphivclwin32/SysUtils_EInOutError.html If an I/O error occurs while this directive is disabled, the application must call IOResult to clear the error. Note: In C++ programs, I/O checking is a project option. The error code is available in the http://delphimaster.net/view/2-1213002154 ErrorCode class member. Error codes are come in ranges: 0-99 (native OS errors) Error codes in the range 0-99 represent OS error conditions, which are different for Windows and Linux. Refer to the OS documentation error 103 for complete error summaries. The SysErrorMessage function returns descriptive text for OS errors. Here are some common OS I/O errors, arranged by rough equivalents in Linux and Windows: LinuxWindows Linux Windows Error Code Description Error Code Description 2 No such file or directory 2 File not found 3 Path not found 5 I/O Error o error 103 13 Permission denied 5 Access denied 20 Not a directory 21 Is a directory 32 Sharing violation Error codes in the range 100 to 149 represent error conditions raised by CLX. Here are the CLX I/O error codes: Error code Meaning 100 End of File 101 Disk Full 102 File variable not assigned 103 File not open 104 File not open for input 105 File not open for output 106 Error in formatted input 107 File already open Delphi Examples: Copy Code { Click the button to open a TOpenDialog, then select a file to delete. } procedure TForm1.Button1Click(Sender: TObject); var F: Textfile; begin OpenDialog1.Title := 'Delete File'; if OpenDialog1.Execute then begin AssignFile(F, OpenDialog1.FileName); try Reset(F); if MessageDlg('Erase ' + OpenDialog1.FileName + '?', mtConfirmation, [mbYes, mbNo], 0) = mrYes then begin CloseFile(F); Erase(F); end; except on EInOutError do MessageDlg('File I/O error.', mtError, [mbOk], 0); end; end; end; See Also IOResult EStreamError SysErrorMessage Copyright(C) 2009 Embarcadero Technologies, Inc.

[0] Здравствуйте.Не поминаю, что произошло, давно не открывал проект, сегодня открыл, кое-что изменил и пытаюсь перекомпилировать, выдаёт ошибку: Project ... raised exception class EInOutError with message "I/O error 103". думал дело с правами, дал полный доступ всем, не помогает... Подскажите, в чем дело? Ega23© (2008-06-09 13:09) [1] 2 минуты поиска в гугле по " io error 103".One of the reasons for error message ‘I/O Error 103’ when it can not get access to a file, either because the file is in use by another program, or because the file does not exist (I"m not expert so maybe there are other reasons too, like double-instances of PTE working on same time thus one instance is using the file and the other can not write to it/or read).
Try to close as many programs working on the background (unvisible too, if you know which). It is good idea to uninstall and re-install again PTE because another possible reason is that a file is missing. I/O stands for input/output which means PTE is trying to write to a file (or read) but can not find it (bad installation) or the file is being used by another program.
It is good also to save the project (pte) before saving a slideshow (exe).
Sometimes (don"t panic) a virus will change attributes of files to "Read-Only" which reasults in inability to write to those files. I don"t believe this is your case but running Anti-virus sometimes can help.
