Using Filestream DOTNET with NAV

OldNavDog

Since the THEY have now RUINED the usefulness of the FILE Commands SEEK and READ...

Yes, the "SEEK" command (and the "READ") are still technically "Supported"; HOWEVER, in NAV 2013 or above, if you attempt to do a READ into a Text Variable that has a Length LONGER than the amount of Bytes "left" to Read, you get a nasty Error.

Reading into an INSTREAM avoids the error (and nicely tells you how many bytes WERE read); but it has no "SEEK" method (!!!!)

:roll:

Other than the hokey suggestions to read into a "char" variable, one character at a time, there doesn't seem to be a way to "skip around" in a file (SEEK) (like FILE.READ supports), but still read-in a potentially shorter-than-variable-length number of bytes (like INSTREAM.READ supports).

I note that the Filestream DOTNET Class (in mscorlib) supports SEEK, and the same "Read n Bytes, or until EOF") functionality; but I'm not good enough with DOTNET to figure out how to make it work from within C/AL. ](*,)

Can someone help?

TIA!!!
