ActiveX

[SSW]

Помогите разобратся, в чем разница, между *.ocx и *.dll компонентами. Какую когда создавать?

[Malaja]

SSW,

naskolko ja znaju, .ocx ispolzuetsja dlja sozdanija swoih kontrolow (naprimer, Microsoft Grid - eto toge .ocx, kotorij ti dobawljaesh w swoj proekt po mere neobhodimosti, on ne pojawljaetsja po umolchaniju na paneli instrumentow), a .dll - dlja sozdanija konkretnogo nabora funkzij, kotorie ti mogesh ispolzowat w razlichnih programmah (.e. 1 raz pishesh i kompiliruesh, a potom dolgo i radostno otowsjudu ispolzuesh). Prichem dll mogno podkljuchit kak staticheski, tak i dinamicheski (eto inogda ochen wagno, osobenno, esli eto pokupnoj soft).

SSW, вот что пишет вебопедия: http://www.webopedia.com/TERM/O/OCX.html
OCX -
Short for OLE Control Extension, an independent program module that can be accessed by other programs in a Windows environment. OCX controls end with a .ocx extension. OCX controls represent Microsoft's second generation of control architecture, the first being VBX controls written in Visual Basic.
Both VBX and OCX controls have now been superseded by ActiveX controls. However, ActiveX is backward compatible with OCX controls, which means that ActiveX containers, such as Microsoft's Internet Explorer, can execute OCX components.
