wininet api help

Thanks to all who read my plea.

I have been working on a program for work that would parse out 'visted' links from the ie history cache. This will be part of a monitoring program to track time used on websites that are beyond the scope of an employees duties. For reasons beyond my understanding, our company won't create a whitelist and enforce with currently available server software applications.

I have studied several examples and have been able to successfully get FindFirstUrlCacheGroup, FindFirstUrlCacheEntry, FindNextUrlCacheEntry, DeleteUrlCacheGroup, and DeleteUrlCacheEntry to work. I however am unable to get FindFirstUrlEntryEx and FindNextUrlEntry to give out any information at all.

It is my understanding that the first set of functions retrieve all entries. This includes cookies, visted and urls. I have so far thined out the results a little by excluding image and script extensions to just get url's. Thus far I have been getting results that are beyond visted links. This would included ad click links for a websites advertisers.

I have also become a little lost in msdn at finding dwFilter bitmask value for the above underlined wininet functions. It says the different possiblites but finding the value is a loss to me.

Any pointers, links, or books that would illuminate my quest at api and c# will be greatly appreciated.
