我有一个带有 MFC 和资源文件的 C++ 项目。在我的关于对话框中，我想添加一个包含程序版本的常量。

IDD_ABOUTBOX DIALOG DISCARDABLE  34, 22, 237, 65
STYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU
CAPTION "About Monitor"
FONT 8, "MS Sans Serif"
BEGIN
    ICON            IDR_MAINFRAME, IDC_STATIC, 11, 22, 20, 20
#ifdef __64BIT__
    LTEXT           "Communication Monitor V" APP_VERSION " x86_64", IDC_STATIC, 40, 13, 150, 8
#else
    LTEXT           "Communication Monitor V" APP_VERSION " x86_32", IDC_STATIC, 40, 13, 150, 8
#endif //__64BIT__
    DEFPUSHBUTTON   "OK", IDOK, 200, 6, 32, 14
END

如果看起来像这样，我会收到错误消息

1>src\monitor.rc(80): error RC2116: expecting number for ID
1>src\monitor.rc(80): error RC2108: expected numerical dialog constant

我还尝试将它与+ 

IDD_ABOUTBOX DIALOG DISCARDABLE  34, 22, 237, 65
STYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU
CAPTION "About Monitor"
FONT 8, "MS Sans Serif"
BEGIN
    ICON            IDR_MAINFRAME, IDC_STATIC, 11, 22, 20, 20
#ifdef __64BIT__
    LTEXT           "Communication Monitor V" + APP_VERSION + " x86_64", IDC_STATIC, 40, 13, 150, 8
#else
    LTEXT           "Communication Monitor V" + APP_VERSION + " x86_32", IDC_STATIC, 40, 13, 150, 8
#endif //__64BIT__
    DEFPUSHBUTTON   "OK", IDOK, 200, 6, 32, 14
END

但我得到了错误

1>src\monitor.rc(80): error RC2237: numeric value expected at 3.1.4.1

我的下一个尝试是像我在顶部定义的函数一样调用它，rc-file但错误就像上面的两个一样。

是否可以在 LTEXT 的 rc 文件中连接字符串和变量？

#define HSTR( N ) #N
#define STR( N ) HSTR( N )
#define VER_TXT( N ) Communication Monitor V##N x86_32
#define VER_STR( N ) STR( VER_TXT( N ) )

适用于VS2013。也应该在 VS2010 上工作。
