Microsoft's P-Code, short for packed code, is an alternate binary format for any compiled binary (eg: DLLs, ActiveX controls, or Applications). Its primary goal is to produce smaller files. Both the Visual C++ and Visual Basic compilers support P-Code.

Using P-Code in Visual Basic

(version 6) Open your project; open the Project Properties dialog; click on the Compile tab; click the option button Compile to P-Code.

Using P-Code in Visual C++

To turn on use of P-Code, use the Pragma directive, ie:

//Turn P-Code on
#pragma optimize("q", on)

//Turn P-Code off
#pragma optimize("q", off)

This feature does not appear to be supported in recent versions of Visual C++, however.
