up Why do I get I/O error 32 even though the file isn't open in any other program? [closed] up vote 0 down vote favorite I'm trying to write a line to a text file in Delphi 7 with the code below, but it gave this error: "Raised Exception Class EInOutError with 'I/O error 32'" AssignFile(trackertxt, 'tracker.txt'); ReWrite(trackertxt); WriteLn(trackertxt, 'left'+':'+':'); CloseFile(trackertxt); It's not being used by any other application, yet it still gives error 32. (Also need it to overwrite the current content in the text file). delphi text-files ioerror share|improve this question edited Apr 29 '13 at 22:25 Rob Kennedy 130k13191354 asked Apr 29 '13 at 20:49 Penian4 1252213 closed as not a real question by David Heffernan, ldav1s, Frank Schmitt, Jean, Derek 朕會功夫 Apr 30 '13 at 22:15 It's difficult to tell what is being asked here.

I wouldn't ask a question if I hadn't already tried to find the answer somewhere else. –Penian4 Apr 29 '13 at
Rewrite(MyOutFile); Now it gives me an "I/O error 32" (with the file existing or not). What is error 32? Where does Delphi hide its error code deciphering? What could be wrong?

Thanks Ralph. Your pointers helped us fix the problem. For the record, here's the story: After digging around the Windows.pas files and all other .pas files containing the word "sharing" I discovered that error code 32 is a generic code for any "undefined" I/O error. ( To quote commdlg.pas: "Note: Undefined return values map to OFN_SHAREWARN, but are reserved for future use.") By stepping and guessing we traced it to a http://www.delphigroups.info/2/a7/334575.html line in a previous function "RmDir(MyDirName)" that failed. Since we were not trapping IO errors with IOResult then all subsequent IO failed (as per help file - - "If an I/O error occurs and I/O-checking is off, all subsequent I/O operations are ignored until a call is made to IOResult. Calling IOResult clears the internal error flag".) Only RmDir causes this and not RemoveDir. So we are now using RemoveDir. Most of the time (all the time?) RemoveDir (and RmDir) fail. Not serious but peculiar.

I occasionally get I/O error 6 or 32. Heres my code: : [source code here, see previous message] http://www.festra.com/wwwboard/messages/13008.html Let's start by looking at what these errors mean.I/O error code 6 means "INVALID FILE HANDLE". In order of probability, that's because: 1. You're trying to use a file that doesn't exist;2. You're http://delphi-techie.faithweb.com/rich_text_4.html trying to use a file that you haven't opened yet;3. Or you're trying to use a file that you have already closed;4. Or you're trying to read more data than your buffer i/o error can hold;5. Or something else.I/O error 32 means "SHARING VIOLATION", in other words: you're trying to access a file which is in use by some other process (in your program or "locked" by another application). Because the errors only show up occasionally, I'm guessing that there is either a timing problem in run-time, or maybe sometimes a file is not found because of a programming error. i/o error 32 So, let's try to narrow it down:- After which line do you receive error code 6? Load your project in the Delphi IDE, and add a debugging "breakpoint" in your source code, a little bit before the place where you expect an error to happen. Next, launch the program by pressing key F9. If you receive an error code 6 before the program halts on the breakpoint, then remove the breakpoint and set a new breakpoint a bit "earlier". Continue doing this until you find out after which line the error code 6 happens. Then, let us know :)- At which line do you receive error code 32? Using the same strategy as above, try to find out after which source code line you are receiving an error code 32.I know that this "trial and error" method can be quite time consuming, but sometimes it's the best you've got available... In the mean time, we'll simulate your application, maybe we get the same errors. Please let me know the results of your tests!
