Command:

• LOCKALLVP Open the dialog to lock or unlock viewports in selected layouts.
• LockAllVp Alias command to run the same dialog workflow.
• _LOCKALLVP Underscore alias for macro use.

Description:

This tool provides a DCL dialog to manage viewport locking by layout, with multi-select layout targeting and per-layout status display.
It is designed to avoid ARX/DCL callback crashes by not running fragile command sequences from dialog callbacks and by applying changes using safer mechanisms where possible.
The list shows each layout name and a computed status: Locked, Unlocked, Mixed, or NoVP.
After clicking Lock or Unlock, the dialog should refresh the list so the status reflects the new state immediately.

Helper function: (if any)

• Unique DCL name Generates a different dialog name each run to avoid conflicts with cached dialogs.
• DCL writer Writes the DCL definition to a temporary file and loads it at runtime, then deletes it on exit.
• Layout collector Builds the layout list (optionally including Model) and applies wildcard filtering using * and ?.
• Viewport scanner Detects Paper Space viewports per layout and determines whether they are locked, unlocked, mixed, or missing.
• Undo stack Stores changes per operation so Undo can revert the last Lock or Unlock action without calling AutoCAD UNDO from DCL callbacks.
• Clipboard copy Copies selected layout names (and their status text) to the Windows clipboard, one line per layout.

Functionalities:

• Filter layouts using wildcard patterns (*, ?) and click Apply to rebuild the displayed list.
• Multi-select layouts from the list for batch processing.
• Select All and Select None for fast selection control.
• Lock all detected Paper Space viewports in the selected layouts.
• Unlock all detected Paper Space viewports in the selected layouts.
• Show per-layout current status (Locked / Unlocked / Mixed / NoVP) so the user can validate before and after changes.
• Undo the last operation (and potentially multiple operations) using an internal restore stack, avoiding unstable undo calls inside the dialog.
• Copy to Clipboard selected layout names and status for documentation or reporting.
• Preserve user environment by restoring CTAB and minimizing command echo during processing.

Result:

The selected layouts will have their Paper Space viewports set to Locked or Unlocked according to the chosen action.
The dialog list updates to reflect the new per-layout status immediately after Lock or Unlock.
Users can export the selected layout list (with status) via Copy to Clipboard for external use.
