Re: class initialize problem 10-Mar-02 22:45 10-Mar-02 22:45  It there no direct way to initialize multi-inherit base class? I get your point, but i guess such a mature language like c++ should have more effect way to do that. thank u after all. Re: class initialize problem Joaquín M López Muñoz10-Mar-02 23:09 Joaquín M López Muñoz 10-Mar-02 23:09  No, the only way to initialize base class(es) of a given class is by using the constructors provided by the class1. This has some motivation, though: it is the responsibilty of a class to maintain internal consistency among its members and base classes, so it is wise to let this class restrain construction of base classes (and even access, for that matter) to implement the particular logic suitable for the context in which these subobjects are used. 1When defining a ctor for a class, under certain special circumnstances (namely virtual derivation) you can directly call constructors from classes that are not direct bases but rather lie farther up the hierarchy. This is a rather messy subject, though, and often it doesn't work as first expected.

(and please excuse my poor english) I would like to find a FREE method to use flow charts in MFC applications. This method can be a CView derived class or an ActiveX control. If you know this type of control/class please answer to this thread because I don't want to develop a complete class if an equivalent exists. Thanks a lot !!! jpeg Aaargh!!

The former, after submitting his novel to the press, went to the country for a small vacation, and some days later he was curious as to how the novel was selling. He wrote this letter to the editor: ? and the answer was ! Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Aaargh!!

This way you'll always know when they are pointing to allocated memory. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Is allocated`?????

Re: Is allocated`????? [James Pullicino]11-Mar-02 0:31 [James Pullicino] 11-Mar-02 0:31  This does is not true when using MFC. In MFC use exceptions to detect out of memory situations: int *ptr1 = 0; try { ptr1 = new int[10]; } catch (CMemoryException *ex) { delete [] ptr1; } (2b || !2b) Re: Is allocated`????? Tim Smith11-Mar-02 2:10 Tim Smith 11-Mar-02 2:10  Nor is it true with VC7 (that is unless you force it to use the VC6 new.) Tim Smith I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?
