view elements of class vector in the debug watch window

[polocar]

Hello,
I'm preparing a Visual C++ 6.0 project.
I use a vector<int> variable (called vec_num), and I noticed that, when I execute the program in debug mode and the execution stops to a breakpoint (after vector initialization), if I try to view the value of an element of the vector (writing for example vec_num[2] in the "Debug Watch Window"), an error is indicated in the value column (CXX0058: Error: overloaded operator not found), as if the subscript operator of the vector couldn't be identified.
The strange thing is that, writing the line
cout << vec_num[2] << endl;
after the breakpoint, the element is printed to monitor without problems.
How is it possible? Is there any way to view the values of vector elements during the execution of a program in debug mode?

Thank you very much
Carlo

It seems it's error in Watch mechanics (Quick Watch can't work too). Some (dirty) workaround: *(v._First+i) works...

Hi ArkM,
I tried to use your suggestion, and I noticed that _First is a protected member of vector, so it can be used only in vector-derivated-classes-code; but this idea suggested me that begin() is an equivalent public method, so
*(v_num.begin()+i) functions...
You are right, it's rather dirty, but at this point I think it's the only way.
Thank you for your help

Hi Polocar,
in debug windows you can see any members, not only public (it's not a common program/language context). Of course, your suggestion (with begin() member) is better than my brute force _First...
