Hi
Inside a function function1 I am writing this line
_bstr_t *linkText5=new _bstr_t[15];
this function is calling function2 where I am assigning a _bstr_t
valuuto linkText5 like this
linkText5[0]=pChild->text;

again in function1 i am writing this line
delete [] linkText5;
But I am getting exception which is unhandled,If I comment the line
linkText5[0]=pChild->text;

then it is exception free.Why?Am I writing anything wrong?

The following sample program worked fine on my machine:

#include <comutil.h>
#include <iostream>

void AssignSomeValue (_bstr_t ArrayOfStrings[])
{
   ArrayOfStrings[0] = "Some text";
}

int main ()
{
   _bstr_t *linkText5 = new _bstr_t[15];
   AssignSomeValue (linkText5);
   std::cout << linkText5[0].operator const char* ();
   delete [] linkText5;
}

Most probably you actually don't want to use an _array_ of strings, but a just a
single string. If so, you shouldn't use pointers or arrays, but just _bstr_t.
