The standard way to do this is PHP. Add #define statements at the beginning of your CSS file, like. #define COLORNAME: #123456; Instead of linking to the CSS file in the head of your HTML file, run a PHP script at that location. The script loads the CSS file, replaces all occurrences of COLORNAME by #123456 and streams the patched text to the ...
May 1, 2011 · Like the C compiler directive, `define is global for the compilation. If your code is ever going to be used with code you don't control you will need to be careful here. Parameters are always local to the module scope so identically named parameters in different design elements will not conflict with each other. They also have the advantage ...
If you need constants (real, compile time constants) you can do that three ways, putting them into header files (there is nothing bad with that): enum {. FOO_SIZE = 1234, BAR_SIZE = 5678. }; #define FOO_SIZE 1234. #define BAR_SIZE 5678. static const int FOO_SIZE = 1234; static const int BAR_SIZE = 5678;
May 18, 2017 · 195. In Kotlin, if you want to create local constants which are supposed to be used within the class, then you can create it like below: val MY_CONSTANT = "Constants". And if you want to create a public constant in Kotlin like public static final in Java, you can create it as follows: companion object {.
Try this: add to the head of the xamlfile. Then Add this to the resource section: Lastly, use a thickness on the margin: <Button.Margin>. <Thickness Top="{StaticResource theMargin}" Left="0" Right="0". Bottom ="{StaticResource theMargin}" />. </Button.Margin>. A lot of system types can be defined this way: int, char, string, DateTime, etc.
Nov 9, 2012 · However, there is a trick that I use for queries sometimes: with const as ( select 1 as val ) select . . . from const cross join <more tables>. That is, I define a CTE called const that has the constants defined there. I can then cross join this into my query, any number of times at any level. I have found this particularly useful when I'm ...
Aug 25, 2008 · DECLARE @Constant INT = 123; SELECT * FROM [some_relation] WHERE [some_attribute] = @Constant OPTION( OPTIMIZE FOR (@Constant = 123)) This tells the query compiler to treat the variable as if it was a constant when creating the execution plan. The down side is that you have to define the value twice.
This means that a constant value is defined in compile time. With the statement: public const TimeSpan theTime = new TimeSpan(13, 0, 0); Are violated two axioms of constant fields: Only the C# built-in types (excluding System.Object) may be declared as const. Iniatialization value must be evaluated in compile time.
According to this article you can define compilation constants in the build tab of your project properties. EDITED: To define build configurations you can go to Build > Configuration manager and I think you can define compilation constants there too.
May 20, 2012 · In Python, I want a class to have some "constants" (practically, variables) which will be common in all subclasses.
