Bring up task manager and see if your program is still rattling around in memory someplace. If so "end task" will take care of it.

That can't help, because the problem is not at the source code level....

496 Destination file write error - During compilation the compiler received a disk write error.
This can occur if the destination EXE is, for example, still running in memory when you attempt to compile, the target file is write locked by another process or compile session, or the target file is write-protected (read-only).

Either the program is still running (bad code logic, not bad code characters in the source code) or some other program has opened the EXE for exclusive use.

Check your end of job logic, you may have left something running which just doesn't have any visible manifestation.

(could also occur on 'directory full' but I think that can only happen on root directories; or if you have a "#COMPILE EXE filename" directive and filename contains invalid characters or an invalid path. )

How do you get rid of ERROR 496?

This code will give you all the possibilities of each number 1-9 for the puzzle: use at your own risk.

Do you have several Threads and don't kill them wenn the program quits ?

Sometimes the OS needs a little bit to give the EXE free.

**Knuth Konrad** · 11 Feb 2008, 05:52 AM

Virus scanner/other security tools may also prevent the EXE from unloading.

**Steve Rossell** · 12 Feb 2008, 11:53 AM

Have you tried rebooting? And does rebooting allow you to compile without error? If these do not help, what about booting into safe mode, does that work? Have you tried compiling to a different path? Are you sure you have write permissions to this directory?

Steve thanks for helping me. I have rebooted, booted to safe mode, compilled to another path, (no help). I am going to rename the file and start removing subs from the file and see what happens. I'll let you know, Thanks Lynn

Steve --- This is crazy, I renamed 'SudokuConsole.bas to Sud.bas for testing purposes (I was going to start removing subs, etc to see if that solved the proplem, guess what! Sud.bas runs fine. I tried renaming Sud.bas to Sudoku.bas - same problem! I tried "copy of SudokuConsole.bas" -- wont work. Renamed it back to Sud.bas -- works fine. Any ideas? I tried renaming the file to Test.bas -- error #496! Renamed it back to Sud.bas and it runs fine!

Could you tell us something about the program / windows version you use ?

I would do a system check with anti virus software and a filesystem check.

**Knuth Konrad** · 13 Feb 2008, 07:24 AM

What about AV software? Have you any "protective" programs running? If so, try disabling them and see if you experience the same problems.

**Guy Dombrowski** · 13 Feb 2008, 09:02 AM

Error 496

Lynn,

Try a search with test.* and SodokuConsole.*
I am willing to bet that you will find a bunch of them and
what you have is a PATH problem

**Lynn Wakefield** · 13 Feb 2008, 10:11 AM

How do you get rid of ERROR 496?

Hubert, I am running windows XP.
I disabled Avast (virus program) - no help.

Guy, I searched and only found duplicates in the windows\prefetch directory.

I also have another computer in my garage running windows XP. Tried the program SudokuConsole.bas on it with the same results (error #496) after compiling it the 2nd time.

**Dale Yarker** · 13 Feb 2008, 10:32 AM

What is the entire path to SudokuConsole.bas?
And entire path to PBCC.exe?

**jcfuller** · 13 Feb 2008, 10:37 AM

Lynn,
What version of PBCC?

James

**Steve Rossell** · 13 Feb 2008, 10:55 AM

You mentioned earlier that you remarked out every line and left only a blank PBMAIN function and still received error 496. But then you said that you need to remove some subs? Does this problem occur if you have only an empty PBMAIN function? What if you create a new program located in a different directory with a different name, does the problem still occur?

**Lynn Wakefield** · 13 Feb 2008, 11:04 PM

How do you get rid of ERROR 496?

jcfuller: I am using PBCC4.04

Steve If I creat or run other programs - - everything is OK.I had the Original SudokuConsole.bas down to an empty PBMAIN function and it still showed the #496 error, thats when I copied SudokuConsole.bas to Sud.bas then it worked ok. But I made some shanges in Sud.bas and now it won't work also. Maybe I should put my source code into the default PPCC4.04 Directory? Can you tell me what is the default directory?

**Fred Buffington** · 14 Feb 2008, 02:36 AM

Wasn't there something in older versions (i dont know about the newer ones) where the exe name was limited to 8 characters ? That may not be a problem but thought id mention it.

**Gary Barnes** · 14 Feb 2008, 03:32 AM

Hi Lynn,
I compiled your code and ran the program several times without any errors.
I initially thought that the problem might lie in the program not shutting down properly and thus locking the executable.
If this was the case then the compiler would not be able to write the new exe file to disk and thus generate an error.
So I am confident that the problem may not be in your code.
May I suggest that you install something like process lasso (free download from Bitsum Technologies) in order to see what is actually running on your computer. Maybe there is another process intervening.
Also another utility called "unlocker" will show you if another program has somehow grabbed your executable, maybe anti malware or anti virus software or even some windows process.
Is there more information?
For example does this problem occur after you have printed something?
Or are you exiting via the close window button instead of pressing 'esc'?
At least if you use process lasso it will tell you if your program is still in memory when you attempt to recompile it.
Another thing to try is to wait for ten or twenty seconds before recompiling, maybe for some reason your program is taking a long time to shut down.
I mention this because I have written applications that didn't close properly until a thread had closed. This may be unlikely because the programs that I wrote were testing the com ports in a thread and until that process had finished the application couldn't properly unload (sloppy programming on my part), also there are no threads in your code.
I hope that this helps you in some way.
I know how frustrating it can be when a program can't be tamed properly

Best Regards
