what is the instruction to set a checkbox to "true" in mql4 programming?

[LEBARTH jean philippe]

I would like to use an instruction like: ObjectSet("m_check_box2",OBJPROP_?,true), but that doesn't work. Is there anyone who could help me? Thanks in advance

1. Why did you post your MT4 question in the MT5 General section instead of the MQL4 section, (bottom of the Root page)?
             General rules and best pratices of the Forum. - General - MQL5 programming forum? (2017)
   Next time, post in the correct place. The moderators will likely move this thread there soon.

2. Where in Object Types - Objects Constants - Constants, Enumerations and Structures - MQL4 Reference do you find a “checkbox.”
