Support for Visual J++ 6.0

The Microsoft extensions in Visual J++ 6.0 that are listed in this topic are fully supported in Visual J#.

To locate reference information for the extensions, see the Visual J++ 6.0 documentation or the Microsoft SDK for Java in the MSDN online library (https://msdn.microsoft.com/library/default.asp?url=/library/en-us/vjcore98/html/vjovrdocumentationmap.asp).

J/Direct (for making calls into native DLLs):
- @dll.import
- @dll.struct
- @dll.structmap
Java-language/COM, for example:
- @com.class
- @com.interface
- @com.method
- @com.parameter
- @com.register
Conditional compilation:
- #if, #elif, #endif, #define
- #warning, #error
- @conditional
  
  Used to mark methods whose calls can be conditionally removed from the generated code.
  
  Note
  
  The @conditional feature works only if the attributed function and the caller are part of the same compilation unit. The recommended technique for using conditional compilation with Visual J# is to use the .NET Framework class ConditionalAttribute.
Delegate and multicast delegate support:
- com.ms.lang.Delegate and com.ms.lang.MulticastDelegate classes
- delegate and multicast keywords
Other @ directives:
- @security
- @hidden
- @deprecated

The Visual J# compiler does not provide the following features that are specific to Java-language bytecodes in the Visual J++ 6.0 compiler:

Ability to import class information from Java-language bytecodes (.class files).
Ability to generate .class files from Java-language sources.
Support for CLASSPATH for resolving referenced classes at compile time; use the /reference (Import Metadata) compiler option instead.
