在C ++(MFC)中的资源文件中串联字符串和常量 [英] Concatenate string and constant in resource file in C++ (MFC)
本文介绍了在C ++(MFC)中的资源文件中串联字符串和常量的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
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.
I have a C++ project with MFC and a resource file. In my About-Dialog I want to add a constant which contains the version of the programm.
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,我会报错
If it looks like this I get an error
1>src\monitor.rc(80): error RC2116: expecting number for ID
1>src\monitor.rc(80): error RC2108: expected numerical dialog constant
我还尝试将其与+
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
但是我得到了错误
1>src\monitor.rc(80): error RC2237: numeric value expected at 3.1.4.1
我的下一个尝试是像在我的rc-file
顶部定义的函数一样调用它,但错误类似于以上两者.
My next try was to call it like a function which I defined at the top of my rc-file
but the error was like the both above.
是否可以在LTEXT内的rc文件中连接字符串和变量?
Is it possible to concatenate a string and a variable in a rc-file within a LTEXT?
推荐答案
#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 ) )
在VS2013上工作.也应该在VS2010上工作.
Works on VS2013. Should work on VS2010, too.
