What is I/O Error 998?

I have a program that executes a thread. The thread opens one file to read and one file to write. My client tells me that he experiences occasional I/O Error 998.

I can't find a reference to this error in the help files.

Does anyone know what causes it?

Could be the No Access error in windows. If your opening a file for write and it is already in use, its possible this error could appear. Ensure that you are properly closing the file after updating it.

From the Win32 help file:

998L ERROR_NOACCESS
Invalid access to memory location.

rfedyk, generally you can use the function "SysUtils.SysErrorMessage" (I hope I remember the correct name) to convert an error number to an error string.
Then you should do proper error/exception handling when opening files. If the opening doesn't work, give out the exact location and the error both in number and string. Then you have a better chance to find the reason for the failure.

Regards, Madshi.
