is there a way to suppress StringFormat from substituting "(missed string parameter) " for missed parameters?
Just curious, is this code working on any version of MT4?
I just tried and after the line
s = StringFormat(s ,__FUNCTION__);
"s" equals to
,,printMarketProfile ,0 ,(missed string parameter) ,(missed string parameter),(missed string parameter),(missed string parameter),(missed string parameter) ,(missed string parameter),(missed string parameter),(missed string parameter),(missed string p
and subsequent StringFormat() calls do nothing because first call "consumed" all format specifiers.
This is with MT4 v646, tried with and without "strict mode".
Nope, no way.
Here's an idea: split your format string into pieces, then create strings and concat them.
Something like:
string mpformat1 = ",,%s ,%i ,%s"; string mpformat2 = "%s,%s,%s,%s ,%s,%s,%s,%s, ,%i ,%d ,%s,%s ,%i,%i% ,%i,%i ,%s"; void printMarketProfile (int x){ s = StringFormat(mpformat1 ,__FUNCTION__,_mkts[x].reason ,_mkts[x].symbol ); s += StringFormat(mpformat2 ,_mkts[x].xcnopen0 ,_mkts[x].xcnclose0 ,_mkts[x].xcnopen1 ,_mkts[x].xcnclose1 ....); Print(s); return; }
Thank you.

I would like to substitute individual variables in a controlled fashion such that changes to a struct can be managed.
