32-bit COM components developed by. NET and C ++ are often included in a large application.ProgramGroup. However, after being deployed to a Windows 64-bit system, the error "retrieving CLSID 80040154 of com-class factory components" may occur.

But today I want to introduce the com implementation in Linux ---- XPCOM, which is the basic technology used in the Mozilla Browser project. We can use C ++ to create the XPCOM component, i

Last night, I was so tired that I was so bored that I was always confused when I got the result for three or more nights: I was unable to create objects by calling C # exported class libraries using vc6, And I used VB to do the same.
