On Windows with MSVS you can use _CrtDumpMemoryLeaks , CrtSetDbgFlag(_CRTDBG_REPORT_FLAG);
_CrtSetDbgFlag(flags) to check memory leaks.
You can google any of these to get some example how to do it

Rahul hook logger applies only to Symbain SDK and not to Nokia Qt SDK.

What do you mean by verified in this context?

Probably a link which you have checked yourself and is known to contain no malicious content. In this case the poster had posted an external link from other forum. The poster might have asked this because some forums restrict posting external links or using short url's.
