Clipboard when used with WCOPY and WPASTE, XLCOPY and XLPASTE commands is already secured.
Warning the following rules must be observed :
• Always do a 'Paste' after a 'Copy' (another program using the clipboard may be stacked).
• Do not do several 'Paste' and only one 'Copy' (there will be not content safety for the next 'Paste' as the first 'Paste' as already released the critical resource').
Clipboard Critical section is named 'CLIPBOARD'. It must be used if the clipboard is used in different ways than with WCOPY/WPASTE/XLCOPY /XLPASTE functions.
