Problem with iTime, assigning "0" to a variable

Sorry for bothering with this rather trivial stuff, but I have spent already too much time on this.

The problem is, assigning the value of iTime() to a variable returns "0", instead of the datetime value.

Any idea?


Inserted Code
Comment(iTime(NULL,PERIOD_M1,0));
prints "1367010960"
Fine.

But:

Inserted Code
BarTime[1] = iTime(NULL,PERIOD_M1,0); //static datetime BarTime[]
Comment(BarTime[1]);
prints "0"

Buffer overflow. static datetime BarTime[] is an array that has not been allocated any memory. BarTime[1] is not a valid variable.

Why? I get no compiling error with this.
Inserted Code
static datetime BarTime[];
BarTime[1] = iTime(NULL,PERIOD_M1,0);

The compiler does not check the bounds of your arrays. You have to do that yourself. GetLastError() returns an error code if you call it after you try to access an array outside its bounds.

static datetime BarTime[] is an array of size zero. Try:

static datetime BarTime[2];

which is an array of size two, BarTime[0] and BarTime[1].

If you want to dynamically allocate arrays you shold use the array functions. In this case ArrayResize(). However I do not know if you can resize static arrays as they are supposed to be STATIC. Check the documentation.

Xaphod, thanks a lot for your answer.
You are absolutely right and the problem got solved right away.
I was looking in a complete wrong direction and would not have figured it out by myself.

Have a nice weekend.
