Hi 

in an indicator that I have written , array out of range error occures, without removing the  indicator from chart

I whant to printf the index amount for my debug 

something like this :

if( _LastError>0) printf(" i is : ", i , "  during error" );//==4002

please some one guide me how is it possible ?

    Your code has already been removed from the chart.

  3. Check your return codes, and report your errors (including market prices and your variables). Don't look at GLE/LE unless you have an error. Don't just silence the compiler (MT5 / MT4+strict), it is trying to help you.

thanks for the reply

as it is clear my problem is not using printformat  or printf .

and surely I can read the manual to learn the correct syntax of printf or printformat.


my question is how can I find out , what is the index amount that cause array out of range error .

i mean how can I print the index amount that is out of array.

for example in OnDeinit or  somewhere else that I do not know?


also despide showing error in experts tab but I still see indicator on my chart

    It is clear that your trouble was exactly the opposite. The printf code you posted was garbage.

  2. Mehrdad Sarrafi #: my question is how can I find out , what is the index amount that cause array out of range error .

    You can't. Your indicator has already crashed. Print before the crash.

  3. If you need help with your code, post your code.

I donot know if you always copy   RTFM and STFW  or not.

I said something like printf  and the code was correct ! 

if you think my problem was working with printf function , it is your problem. please read the topic and question one more time.


====>>>  I want print the exact number of index that cause , array out of range <<<=====

do you have any idea about that ?

something like printing error description

 thanks

this help me to solve the problem by silencing !!!

but my question still remain for my curiousity  and

because when I use #property strict , again show me  array , out of range in expert tab in metatrader , and one of the buffer in my indicator isnot drawn
