vc++ 6--add member function, using macros
-
1)On p.370 of Ivor Horton's Beginning Visual C++ 6, it says you can add operator functions to the class by clicking on the down arrow to the right of the Wizard bar and selecting Add Member Function. I tried that, and after I entered the first operator function, the declaration was added to the class in the .h file, and a skeleton function definition was added to the .cpp file. So far, so good. Then, when I tried to add a second operator function, it only added a skeleton function definition to the .cpp file and would not add the declaration to the .h file. How can I get it to do that? 2)A little later in the chapter on p. 374, it says that instead of typing in preprocessor functions into the header file, you can use a macro in VC++6 that will do it for you. The book says to click on Tools/Macro and select OneTimeInclude from the macros list in the Macro dialog box that pops up. My macros list is blank in the dialog box. I tried typing in OneTimeInclude, but I got an error that said I had to choose a macro from the list--what list, it's blank?!

1. Burn the wizard, learn to do it yourself. You obviously know where things need to go, so put them there. Wizards are good to help you get started, but you should always move beyond them and learn to use the language more than the IDE. 2. I've never used this because macros are evil. The one time include should be present anyhow, when the class is generated by the wizard. Apart from this you should not use macros unless you really need them, i.e. where a const variable or inline function will not do the trick. In the real world, that generally means when you're writing debugging/tracing tools. Christian NO MATTER HOW MUCH BIG IS THE WORD SIZE ,THE DATA MUCT BE TRANSPORTED INTO THE CPU. - Vinod Sharma

The page you requested cannot be found.
Click here to go to the CodeProject home page,
or click here to return to the previous page.Do I have to reinstall Internet Explorer to get the correct page? I am using XP Home by the way with a black mouse pad! You never know if it is the environment that is causing the error. Awaiting your kind response please, Respects, Nish :rolleyes:

Thanks for responding. 1)I would rather save myself the hassle of having to type the function header twice: once in the class definition and once in the function definition. For some reason the wizard has a problem with operator functions in the class definition: it doesn't seem to recognize that operator+() is different than operator*(), but it does in the class implementation file because it adds a new skeleton function definition there. 2)I don't really understand your explanation here. As far as I can determine, the macro I'm supposed to run adds the preprocessor directives to my .h file--not a macro--so that once again it will save me the hassle of typing them in myself. Do you use VC++ 6? If so, could you click on Tools/Macro and tell me if OneTimeInclude is in the list of macros? Thanks

If I add a class using the wizard, I get an include guard, if I write my own, I write my own include guard, again relying on copy/paste. 7stud wrote: If so, could you click on Tools/Macro and tell me if OneTimeInclude is in the list of macros? It's empty, as I would expect. I'd expect this to include macros as in UI sequences I recorded, not macros as in #define BLAH blah Christian NO MATTER HOW MUCH BIG IS THE WORD SIZE ,THE DATA MUCT BE TRANSPORTED INTO THE CPU. - Vinod Sharma

I'd expect this to include macros as in UI sequences I recorded, not macros as in #define BLAH blah After several days of messing around with this macro deal, I finally figured it out. If you're interested, with no files open in VC++6 click on Tools\Macro, then click on Options/Loaded Files, and the "Add ins and Macro files" tab should be selected(if not select it). There is a macro called Sample which you should enable by clicking on the check box. Then click on Close. From then on when the Macro dialog box appears after you click on Tools\Macros, you can select Sample as the "Macro file:", and from the list you can choose OneTimeInclude. When you click on Run, the macro will add your preprocessor directives for you. There are also other sample macros that are probably useful. Thanks for your help.
