Can anyone figure out how to extend this software divide routine to have a 16-bit quotient

Asked 2020-Oct-30 at 11:06

Background...

I am currently trying to extend an assembly routine for an MCS-48 (which has no hardware divide) from the current 8-bit quotient, to a 16-bit quotient

This is a scan of the original routine here: http://techmattmillman.s3.amazonaws.com/wp-content/uploads/2020/10/isisdiv.png

(yes, that is from a dot-matrix printer). I have faithfully translated it to 'C' code, and have verified that it works the same as the original:

Since this is a simple bit-wise longhand binary division, the minimalist approach would be to change uint8_t to uint16_t, uint16_t to uint32_t, bit 15 to bit 31, 0x8000 to 0x80000000u, 0xff to 0xffff, 8 to 16, and so on.

When I do that, the resulting code seems to work correctly, although an exhaustive test would take a few days from what I can see, so in the "smoke" test below I am using random test vectors.

QUESTION

Writing or Copying File To Network Share in C#

Asked 2017-Jun-07 at 21:51

I've written a Windows Service that impersonates session 0 to access local printers and prints money orders to networked dot-matrix printers. That part works great, and the idea is that the client terminals (running 3.5 desktop app) will generate an xml file that is written to (or copied, I don't care) to a share on that machine, and the Print Queue Service will pick these up every few seconds, order them by number and store, and send the job to the correct store's printer. That all works.

However our issue is that we can't save the xml files to the remote share without first saving credentials on every single computer. Despite sharing it with EVERYONE having read/write/modify access to the share, it won't work. Obviously the client is unwilling to type in a username and password for 300+ computers.

I've tried everything I can think of. I've tried impersonation using WindowsIdentity and WindowsImpersonationContext, but I always get "The name provided is not a properly formed account name." no matter if I use name@domain or domain\name, or the application quits with no error messages logged in the event viewer or our database. I've tried using the code found here which maps the drive successfully but I am denied access to it. I've tried alternative code to use LogonUser from the Windows API (doesn't work). I've shared and re-shared the folder with the least restrictive permissions I can find. Nothing works.

Any suggestions on what we can do at this point? The code is here:
