Can I check if CTRL or SHIFT is pressed when using CHARTEVENT_KEYDOWN?

[Marbo]

Hi guys,

I just used CHARTEVENT_KEYDOWN this way:

if (lparam=="A")...

Is it somehow possible to check if SHIFT and A are pressed? I didn't find anything about it in the MQL4 docs.

SHIFT = 16

CTRL  = 17

apirakkamjan:

SHIFT = 16

CTRL  = 17

Thanks! But I can't do it this:

if (lparam==16 && lparam=="A") ....

So how can I check if SHIFT and A are pressed together?
