a ? b : (c ? d : e) Tip You can use the following mnemonic device to remember how the conditional operator is evaluated: text is this condition true ? yes : no Conditional ref expression A conditional ref expression conditionally returns a variable reference, as the following example shows...

( -> Properties for My Project, -> C/C++ Build -> Build Variables; Configuration: TEST ) In the source code i place a : #ifdef TEST_ACTIVE (Code between) #endif I set Configuration TEST active, but the compiler doesn't know the Variable "TEST_ACTIVE". ...
Hi, I have a need to highlight a set of cells based on whether or not a date (date is concatenated based on multiple other cells) =TODAY(). Heres...
The preceding example is a thread-safe way to ensure that only a non-nullhandleris invoked. Because delegate instances are immutable, no thread can change the object referenced by thehandlerlocal variable. In particular, if the code executed by another thread unsubscribes from thePropertyChangedevent...
This enhancement doesn't classify a null conditional expression as a variable. It can't be ref assigned, nor can it be assigned to a ref variable or passed to a method as a ref or out argument. Thread-safe delegate invocation Use the ?. operator to check if a delegate is non-null an...
The Macro below works perfectly when column “L” is filled with numbers BUT it will actually be filled with dates, and I cannot work out how to make it...
We do this in order to set the variable to the value of zero, as we will be using it as a counter. On line 3, we set up our while loop, while [$i –lt 4]. This means that while the value stored in i is less than 4, we should keep executing the while loop. We then see...
Random forests are becoming increasingly popular in many scientific fields because they can cope with "small n large p" problems, complex interactions and even highly correlated predictor variables. Their variable importance measures have recently been s
