eDNC Special Character Fix - Claude Code Instructions

Project Overview

PowerShell utility that monitors DNC folders and removes invalid special characters (0xFF) from .pun files in real-time. Deployed to CNC workstations via network share.

Technology Stack

• Language: PowerShell 5.1+
• Deployment: Network share (S:\DT\cameron\eDNC-Fix) → Local (C:\eDNC-Fix)
• Logging: ShopDB API (http://geitshopdb/api.asp)
• Version Control: Gitea (localhost:3000/cproudlock/edncfix)

IMPORTANT: After Making Changes

Always do the following after any code changes:

1. Update version numbers in ALL of these files:

   • eDNC-SpecialCharFix.ps1 - $ScriptVersion variable (line ~81)
   • eDNC-SpecialCharFix.ps1 - .NOTES section Version field
   • version.ini - Version=x.x.x
   • README.md - Version History table

2. Commit and push to Gitea:

   cd /home/camp/projects/powershell/edncfix
   git add -A
   git commit -m "vX.X.X: Description of changes"
   git push
   

3. Version format: Use semantic versioning (MAJOR.MINOR.PATCH)

   • MAJOR: Breaking changes
   • MINOR: New features
   • PATCH: Bug fixes

ShopDB API Integration

The script logs events to ShopDB via the API. Reference the ShopDB API documentation at:

• ShopDB Project: /home/camp/projects/windows/shopdb/
• API File: /home/camp/projects/windows/shopdb/api.asp
• Standards Doc: /home/camp/projects/windows/shopdb/docs/STANDARDS.md

API Endpoint: logDNCEvent

Method: POST URL: http://geitshopdb/api.asp

Parameters:

Parameter	Type	Required	Description
action	string	Yes	Must be "logDNCEvent"
hostname	string	Yes	PC hostname
eventType	string	Yes	Event type: started, cleaned, ok, failed, error, stopped
filename	string	No	File being processed
bytesRemoved	int	No	Number of bytes removed
version	string	No	Script version
message	string	No	Additional details
watchFolder	string	No	Folder being watched
fileFilter	string	No	File filter pattern

Database Tables:

• ednclogs - Event log entries (uses machineid FK to machines table)
• installedapps - Tracks installations (appid=79 for eDNC)

API Endpoint: getDNCStats

Method: GET URL: http://geitshopdb/api.asp?action=getDNCStats

Returns JSON with all eDNC installations and their stats.

Deployment Workflow

1. Development: Edit files in /home/camp/projects/powershell/edncfix/
2. Update versions: Bump all version numbers
3. Commit: Push to Gitea
4. Stage: Copy files to S:\DT\cameron\eDNC-Fix\
5. Deploy: On target PC, run Deploy.bat from S: drive
6. Install: Run Install-ScheduledTask.ps1 as Admin

Auto-Update Mechanism

Running instances check S:\DT\cameron\eDNC-Fix\version.ini every 5 minutes. If a newer version is found, they automatically:

1. Copy new files from S: to C:\eDNC-Fix\
2. Restart themselves

To deploy an update to all PCs:

1. Update version.ini with new version number
2. Copy updated files to S:\DT\cameron\eDNC-Fix\
3. Wait up to 5 minutes for auto-update
