The WinAPI mql bible has this function

Your types are different, they must be from C#

---

So my question is: where is it right?

interesting questions you have ))))

if in doubt, go tohttps://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-getvolumeinformationw

Sharp has nothing to do with it.

read "preprocessor" in Wiki and "macro substitution" in MQL help - maybe something will become clear

Before asking a question, I searched for an answer using your link too.

I'm confused by difference of types, e.g., mql: ushort volume_name_buffer , butLPWSTRvolume_name_buffer in official documentation

That's why this question is"where is correct?", but rather the exact question: "what is correct to use in an mql program?"

 
Vitaly Muzichenko:

both examples will be the same after the compiler preprocessor works, well look at the help, what does macro substitution do

which one to use? - it's a matter of taste, i would use the first one - it's clear to me immediately that this code implies calling WinApi -

 
Traditionally, such code is copied from MS API documentation.
Defines are needed to avoid rewriting ready-made code for MQ5.
 
Anybody there!?
 

I haven't seen anyone write this before, it turns out that to change the MT5 icon to a branded one, just replace Terminal.ico in the folder,

so many years of struggling with a bunch of identical terminals

Jeez... I've had different icons for a long time. And I have these.

I can share...

I create custom icons and substitute them, so that in the taskbar it is immediately visible what and where it works.

 

It's easy to control.

Object*-functions are very laggy if you drag the graph with the mouse.
