You could at least summarise the problem, so that people will know if their skills are good enough to spend their valuable time helping you instead of swearing at each other in the soapbox.

I look at these forums in gaps of a few minutes while some large compilations happen - I'm not going to start following links off site in case I may be able to help. And I'm sure that's true for a lot of the more regular helpers.

We're nice - but you need to help us to help you.

Iain.

Very well said!

The only thing I do not understand: What is wrong with swearing at each other in the soapbox? Poke tongue | ;-P

Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

The lid of the soapbox is broken, so falling into the box hurts! Poke tongue | ;-P

Nothing at all. That's why time away from it has to be justified!

deletion of void pointer

Consider the following code:

XYZ* pXYZ = new XYZ();
void* pvoid = pXYZ;
delete pvoid;

my question is whether the XYZ object will be properly deleted thru the pvoid pointer WITHOUT typecasting? If the answer is no, then how does the 'free' delete using void pointers without knowing the amount of blocks that are to be freed?

Well the pointer will be deleted but not properly. The reason being that deleting a void pointer won't call that pointer's destructor function which will result in leaks if you have nested objects which in turn allocate memory.

Always pair "new" and "delete". Don't try to "new" and then use "free". "new" calls the constructor and "delete" calls the destructor. This allows all nested objects(which relies on the container class's destructor) to free themselves properly.

Well answered. So well answered, that I tried to look at your blog. The link in your sig points to...

http://www.codeproject.com/script/Forums/%5C%5Cnibuthomas.wordpress.com[^]

Which you may want to change! I'm guessing changing /'s to \'s will help.

(And yes, I can edit the link I go to - may be that's a test to qualify for entry to your blog?)

Why have you created a new thread for asking something that you have asked in one of your earlier posts? There are some people trying to help you there and so I advice you to be patient and wait for someone to answer your question.

Don't expect that making a repost of the your questions by creating a new thread will get you answers quickly. If people have not been able to help you in the original thread, then its unlikely that they will answer here.

And seriously, though you have asked the question twice, i am still not able to figure out what you exactly want.

Regards,
Vijay.
