Delphi Einouterror I/o Error 6
Contents |
I occasionally get I/O error 6 or 32. Heres my code: : [source code here, see previous message] delphi i/o error 32 Let's start by looking at what these errors mean.I/O error code 6 means delphi i/o error 103 "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
Delphi Assignfile
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 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. 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!

[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.

I wouldn't ask a question if I hadn't already tried to find the answer somewhere else. –Penian4 Apr 29 '13 at 21:00 2 Error code 32 means: "The process cannot access the file because it is being used by another process." –Jerry Dodge Apr 29 '13 at 21:00 2 Well, clearly something else has

It may be that you have declared the read buffer before the File variable, and are trying to read more data than the buffer can hold. The buffer overflowes and your File variable is overwritten with the buffer overflow. I once had this problem myself and was unable to find what I/O error 6 meant. I had to find an old manual from Turbo Pascal for Windows to delphi i/o error find a description of the error code. Hope this helps.
