1. You read the Tick Number from the Order History
2. You add each Ticket using the class method "AddItem".

Obviously, you must first learn to code in general and learn about OOP - Object Oriented Programming. Otherwise you will not be able to understand it, much less code it!

I don't have an example, but you yourself have referenced the documentation as well as a Forum thread with an example, and yet you could not do it.

You are missing the point. You have to first learn OOP, because once you do you will not need an example.

You need to to learn C and C++ to better understand coding in MQL, especially if you come form an Visual Basic background!

There is no way around this. It is part of the learning curve if you want to code and understand MQL properly.

does anyone tell me how it works?

There is plenty of examples in the Codebase, Articles and even on the Forum. You just have to search a bit.

I don't think someone will do it for you.

I also have been unable to find a good example of using the CCombobox class in an expert. Not in any articles blog posts or code. I can use one in an indicator as Amando mentioned but have been unable to get one to work properly in an Expert thus far. If anyone has a code example of it. please include it... I hardly am finding "plenty of examples in the Codebase".. Just one would suffice.
