How to Specify Macros in Directives or Text
| Overviews | How Do I | Details |
Feature Only in Professional and Enterprise Editions Creating a Custom AppWizard is supported only in Visual C++ Professional and Enterprise Editions. For more information, see .
A macro name that is used as an argument to a directive, such as $$IF, does not need dollar signs ($$) to mark its beginning and end; any dollar signs found are interpreted as part of the macro’s name. For instance, the CCustomAppWiz::ProcessTemplate function’s parser treats both AMACRO and $$AMACRO$$ as macro names in the following two directive statements:
$$IF(AMACRO);
$$IF($$AMACRO$$);
A macro name in text, however, requires dollar signs ($$) to mark its beginning and end, as shown in the following fragment extracted from one of AppWizard’s custom resource templates:
///////////////////////////////////////////////////////
// $$APP_CLASS$$
BEGIN_MESSAGE_MAP($$APP_CLASS$$, $$APP_BASE_CLASS$$)
//{{AFX_MSG_MAP($$APP_CLASS$$)
$$IF(VERBOSE)
// NOTE - the ClassWizard will add and
// remove mapping macros here.
// DO NOT EDIT what you see in these
// blocks of generated code!
$$ENDIF
//}}AFX_MSG
ON_COMMAND(ID_HELP, CWinApp::OnHelp)
END_MESSAGE_MAP()
