This article was previously published under Q150076 SYMPTOMS When compiling a Microsoft Foundation Class (MFC)
application that uses the Windowsx.h header file and calls
CWnd::SubclassWindow(), you may get the following error:
warning C4003: not enough actual parameters for macro 'SubclassWindow' error
C2059: syntax error : ')' CAUSE The Windowsx.h file is a header that includes message
cracker macros to help programmers write more portable Windows-based
applications. The header file contains a preprocessor macro named
SubclassWindow. The macro bears the same name as the CWnd::SubclassWindow()
member function. The macro has two parameters; the member function has only one
parameter. The preprocessor tries to expand the symbol SubclassWindow when it
is found. RESOLUTION You can un-define the macro as follows:
#undef SubclassWindow
STATUS Microsoft has confirmed this to be a bug in the Microsoft
products listed at the beginning of this article. REFERENCES Win32 SDK Books Online.
