Newbie question: Do I need to enable Alert() and Print() function before using them ?

New comment
 

I created an simple EA and only droped following two lines in the "Start()" function.


Alert("1111121");

Print("1111121");


compiled it and return back to MetaTrader terminal. then I added this EA on EUR/USD 1 min chart. wait for about 5 mins. no Alert pop out, checked "expert" tab, "1111121" didnt show up there.


Do I accidently changed some settings and disable those 2 functions?


Please help me.

Have you got a smiley face beside the EA on the chart?

yes, smiley face is there, next to the EA name. its at upper right corner.


I pretty sure code is correct. probably somewhere I messed up the setting.

 
nothing wrong with my code, i just reboot my computer. now, its working, alert box showed up. I didn't turn it off for about a week. this is weird.

i used a long time win98.

after 24 hours the system crashed.

later i found out, that this is a win98 bug, because a internal counter overflows.


if you dont use linux, is always a godd advise to reboot the system in regularly intervals.

sure there are other systems that are stable over month, but i only know of some linux distributions.


besides that, MT4 crash relativ often, but this may depend on my code (divison by zero or endless loops etc)

sometimes only a reboot helped in my case


greetings
