Can anyone share a handy windows/chart manager? Need alphabetical sorting of the list, contextual search, hierarchical display of all downloaded EAs, scripts, indicators; fast switching.

[Mihail Matkovskij]

Stanislav Korotky:
Is there any way to know that MQL-program was started as a result of terminal start (i.e. automatically at the beginning of session) and not interactively by user?

You can write to the reason file at OnDeinit and load it at startup. If the loadedreason wasREASON_CLOSE, then the program was loaded as a result of terminal start(because it was terminated as a result of closing it). If it's not there or different, then different...

Try the patched version of the ControlsPlus windows and controls library from this article. There, the rubberization was supported automatically.

Thanks, but that's not it, at all. Need to tweak code that works on SB

What do you mean it's not the same at all? I offered to take the patched SB version, which solved the above problem. Well, you're the boss.

Perhaps F2 in the Terminal of a fresh build will partly help.

You have to carry it everywhere, and the SB is always there. That's the key "wrong".

What you need is a variant of the edit with an SB.

Despite what the documentation says, GlobalVariableCheck () does not change the access time.

Возвращаемое значение

Returns the time of the last access to the specified global variable. Accessing the variable for a value, e.g. using GlobalVariableGet() and GlobalVariableCheck(), also changes the last access time. To get the error information, call GetLastError().

Fix either the documentation or the behaviour of the function.
