Comments
IOleCache::InitCache is usually used when creating an object from a drag-and-drop operation or from
a clipboard paste operation. It fills the cache as needed with presentation
data from all the data formats provided by the data object provided on the
clipboard or in the drag-and-drop operation. Helper functions like OleCreateFromData or OleCreateLinkFromData call this method when needed. If a container does not use these helper
functions to create compound document objects, it can use IOleCache::Cache to set up the cache entries which are then filled by IOleCache::InitCache.

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications.

Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
