How to extend the Event data
The custom event can carry only very tiny data. The MQL4 event data is limited to three numbers (short, long, double) and a string (up to 65 characters), inclusive the event identification. Not really much for working with objects.
I would like to append a custom structure to the custom event.
How do you append more data to the event? (a question for coders, not the local spammers). I do not intend to use a DLL for passing a pointer of the structure. I am afraid that I cannot avoid storing the data structure to an MQL file, which is somewhat ugly design.
If you can not hold you to display openly your contempt for most members of this forum, there is no need to waste your time here. This is my last warning.
It is your private fight, Angevoyageur.
It is not me, it is you who keeps offending people here. You may remove this topic, I am not interested in nervous offtopic discussions with a moderator.

| You can't modify the MQL structure and there is no need to | myObject* gObjects[];
OnEvent(int i){ gObjects[i].OnEvent(); }
Use the number to select your object. Don't try to pass an object to MQL4 only to get it back. |
