Tommaso,
Just noticed that in addition to doing a shipload of coding, pointing people in the right direction (as you did for me), you also provide general IT help. Be Blessed!

my Empty4 Build 646 often crashes with the 10.7 templates. So I checked the used indicators.

At the indicator 10.7 INDI DP.mq4 I received a compilation warning:

Code: Select all

declaration of 'i' hides global declaration at line 76	10.7 INDI DP.mq4	237	8

I think that is not the big mistake, but I will fix that.

Question:
What must I do to terminate that warning message?


Thanks a lot!

this is a warning not causing any error, but you can attch your indi, if you want the warning removed, I will do it..

Cheers

Hi Tommaso,

I know that this is only a warning. But I think that have to do with the new
coding roules of the Empty4 6.x Version.

I had an other indi with warnings too. So if I learn what goes wrong, I am able
to fix the other warnings too.

At the DP Indicator is the problem, that the variable i is global?

So the variable must be initialisated inside the init() part?

delete the
int i;
from global initialisation.

set into the init() section:

Code: Select all

   pregap=""; 
   int i;  
   for(i=0; i<text_shift;i++) pregap = pregap + " ";
   if(addMidLevels == true) timeframe_prefix = timeframe_prefix + "Mid ";
   timeframe_prefix_text = pregap + timeframe_prefix;
      
   SetIndexLabel(0,timeframe_prefix + "Pivot Point");

The indi works an I receive no warnings.

Is that the solution??

the error means that you use in a function for a new only functionwide intialised variable the same name, as for a global used variable , what indeed should be avoided in clean coding, just rename i in the function..

That means, it is alowed to use always i at any loops, but only in separate funktions?

Is it wrong to use one times var i at init() section and one time at start() section?

no, you can use it in all functions, if you have defined i as a global variable.
