Hi, I'm new to Objective-C and I saw the "new type" BOOL (YES, NO). I read that this type is almost like a char. For testing I did : NSLog(@"Size of BOOL %d", sizeof(BOOL)); NSLog(@"Size of bool %d", sizeof(bool)); Good to see that both logs display "1" (sometimes in C++ bool is an int and its sizeof is 4) So I was just wondering ...
Hi, Could you please tell me if there is a way to pass the parameter of boolean type from reporting services to PL/SQL. I tried using data type boolean in PL/SQL that is not allowing me to create the dataset. my report is having a radio button , asking for the sort order asc or desc. i was thinking of sorting it from the procedure sid...
I guess this is trivial for most of good1 programmers, but I'm so used to programming using true and false2 that when I encounter 0 and 1, I can never remember which one means true and which one means false. Any suggestions? 1Good: I mean one who knows C, of course :) 2I am a Java developer, as you have guessed ;) ...
hi, How do i pass a boolean type parameter from SSRS to boolean type in PL/SQL stored procedure. Any idea, i wanted to have the report parameter as radio button in my report design. Please help me to get an idea, if there is a way. thanks, San ...
So, I need to find out how to do a fulltext boolean search on a MySQL database to return a record containg the term "C++". I have my SQL search string as: SELECT * FROM mytable WHERE MATCH (field1, field2, field3) AGAINST ("C++" IN BOOLEAN MODE) Although all of my fields contain the string C++, it is never returned in the search resu...
Does Ruby have a plain-English keyword for exclusive or, like they have "and" and "or"? If not, is this because exclusive or doesn't allow evaluation short-cutting? ...
These are my questions: I'm getting a couple of errors on the line "public static boolean validNumCheck(String num){" - "illegal start of expression", "';' expected", and "')' expected". How can I give the user 3 tries in total for each number? I believe right now the programme asks the user for 3 numbers and gives them 3 tries in tota...
I am querying a MySQL database in python and selecting a boolean value -- so the response from MySQL is either the string 'True' or 'False'. I would like to execute further code based on the boolean value from MySQL. E.g. data = 'False' # assume this is what was returned by MySQL. if data: print 'Success' #really this would be whe...
I just want to flip a boolean based on what it already is. If it's true - make it false. If it's false - make it true. Here is my code excerpt: switch(wParam) { case VK_F11: if (flipVal == true) { flipVal = false; } else { flipVal = true; } break; case VK_F12: if (otherVal == true) { otherValVal = false; } els...
Simple question really; is there a difference between these values (and is there a difference between BOOL and bool)? A co-worker mentioned that they evaluate to different things in objective-c, but when i looked at the typedefs in their respective .h files, YES/TRUE/true were all defined to 1 and NO/FALSE/false were all defined to 0. ...
Whenever BOOL datatype is not readily predefined, I used to boolean with the following definition, typedef unsigned char BOOL; (Owing to memory usage). I realized it may be better to use native bus width for performance reasons. For example, for a 32 bit processor it can be typedef unsigned int BOOL; Now, what will happen for the 64...
I'm sending xml to another program, which expects boolean flags as "yes" or "no", rather than "true" or "false". I have a class defined like: [XmlRoot()] public class Foo { public bool Bar { get; set; } } When I serialize it, my output looks like this: <Foo><Bar>true</Bar></Foo> But I would like it to be this: <Foo><Bar>yes</...
I need to utilize an array of booleans in objective-c. I've got it mostly set up, but the compiler throws a warning at the following statement: [updated_users replaceObjectAtIndex:index withObject:YES]; This is, I'm sure, because YES is simply not an object; it's a primitive. Regardless, I need to do this, and would greatly appreciate...
I have a string called word and a function called infinitive such that word.infinitive would return another string on some occasions and an empty string otherwise I am trying to find an elegant ruby one line expression for the code-snippet below if word.infinitive == "" return word else return word.infinitive Had infinitive re...
If I declare a JavaScript boolean variable like this: var IsLoggedIn; And then initialize it with either 'true' or 1, is that safe? Or will initializing it with 1 make the variable a number? ...
Have you ever seen any library/code that overloaded boolean operators, which is said to be evil? and What advantages does it give to the user? ...
There are a few ways to do this in javascript. Foremost and most readable and flexible is probably: if (a){ //b } else { //c } Something else that only* works with assigning and is less readable is: var foo = 'c'; if (a){ foo = 'b'; } My main question, though, is about the last two methods I can think of: var foo = a ...
I need to parse complex expresion from string to bool. It can only contain: * boolean values (true/false), * parenthesis, * AND/OR operands (&&, ||) Eg: bool.Parse("((true || false) && (false || false)) || (true || false)" Any idea how to achieve this? ...
In different assembly languages MUL (x86)/MULT (mips) refer to multiplication. It is a black box for the programmer. I am interested in how actually a CPU accomplishes a multiplication regardless of the architecture. Lets say I have two 16-bit values in my registers and I am the cpu, so I have to implement MUL using the other bit-fiddlin...
I have a list. I want to convert it to a byte[]. How do i do this? .toarray() creates a bool[]. ...
