I found them here: http://oatmeal.googlecode.com/svn-history/r1/backup/MetaTrader/4/Libraries/WinCmd.mqh
Would be good to have them officially documented somewhere.
@WHRoeder :))))))))) it works!!! I feel so relieved that finally I can speed up lines creation :))) Thank you very much!
What are the values for the other buttons (all shapes, all arrows, cursor and crosshair)? Are they documented somewhere? Similar to MT4_WMCMD_HLINE 33244.
