Oct 30, 2013 · 14. In C# #define macros, like some of Bernard's examples, are not allowed. The only common use of #define / #if s in C# is for adding optional debug only code. For example: static void Main(string[] args) //this only compiles if in DEBUG. Console.WriteLine("DEBUG") //this only compiles if not in DEBUG.
Oct 25, 2017 · @jwodder - I agree with you. OTOH, there are at least 24 people for which this was useful. Perhaps it was the fact that he covered ítems in the comments of the accepted answer: 1) format of explicit paths, 2) how to get examples of such (with getcwd).... remarkable.
Nov 27, 2015 · The #define directive has two common uses. The first one, is control how the compiler will act. To do this, we also need #undef, #ifdef and #ifndef. (and #endif too...) You can make "compiler logic" this way. A common use is to activate or not a debug portion of the code, like that: #ifdef DEBUG. //debug code here.
A good way to understand what the preprocessor does to your code is to get hold of the preprocessed output and look at it. This is how to do it for Windows: Create a simple file called test.cpp and put it in a folder, say c:\temp. Mine looks like this: #define dog_suffix( variable_name ) variable_name##dog. int main()
Sep 25, 2014 · If the worksheet is created at run-time (inside ThisWorkbook or not), then you need to declare & assign a Worksheet variable for it. Use the Worksheets property of a Workbook object to retrieve it: Dim wb As Workbook. Set wb = Application.Workbooks.Open(path) Dim ws As Worksheet.
3. #ifndef checks whether the given token has been #defined earlier in the file or in an included file; if not, it includes the code between it and the closing #else or, if no #else is present, #endif statement. #ifndef is often used to make header files idempotent by defining a token once the file has been included and checking that the token ...
May 1, 2016 · Sure this is possible. The #define is processed by the preprocessor before the compiler does anything. It is a simple text replacement. The preprocessor doesn't even know if the line of code is inside or outside a function, class or whatever. By the way, it is generally considered bad style to define preprocessor macros in C++.
Dec 18, 2020 · #define identifier token-sequence The preprocessor runs before the compiler transforms your code for use in the compiler. The order is as follows: Trigraph replacement; Line splicing; Macro definition and expansion; So with the #define you can have character manipulation (macro substitution). Whenever M is seen 4 will be substituted.
Jul 27, 2010 · Greg's answer works fine in a .pro file. However, when calling qmake from the command line, I had to leave away the spaces, i.e. use sth. like the following, to make a define work : qmake DEFINES+="WINVER 0x0500"
Mar 7, 2017 · 2. If you want the code represented by the second comment section to always run, just do. #ifdef PROC_ADD. // Do the stuff to be done if PROC_ADD is defined. #undef PROC_ADD. #endif. // Do the stuff to always be done. If you want run-time behaviour changes, you must use run-time constructs (such as a variable to serve as a flag).
