用于识别VB6应用程序中的内存占用的工具

What tools are available to attribute memory consumptions in VB6 application to it's multiple components? I can get the memory consumed by the entire application by watching various counters (Private Bytes, Working Set etc.), for example, in Process Explorer. I want to go level deeper than that and understand how much memory is consumed by various components or objects created at runtime. For example, figure out how much memory is consumed by large collection that's caching data at run time and how it changes based on number of elements in the collection.What tools are available to attribute memory co
