Here is the question which is Re Phrased.
Here is the raw binary data, hex encoded, which i need as a output:
040000008200E00074C5B7101A82E0080000000000000000000000000000000000000000310000007643616C2D5569640100000033353335324538372D343338462D343444362D413432462D37393942423334313033333800
I can extract some part of the raw data i.e.(040000008200E00074C5B7101A82E0080000000000000000000000000000000000000000310000007643616C2D55696401000000) from the object which i am getting from the micro soft outlook.
The Rest of the part that is
33353335324538372D343338462D343444362D413432462D373939424233343130333338 is the conversion of the UID : 373D06E9-587E-4930-B846-12500FF1AC2F.
So My question here is how to convert the above UID i.e 373D06E9-587E-4930-B846-12500FF1AC2F to this format 33353335324538372D343338462D343444362D413432462D373939424233343130333338 using objective C or cocoa.
Thanks in Advance.
You should look here:
https://developer.apple.com/library/mac/documentation/corefoundation/Reference/CFUUIDRef/Reference/reference.html#//apple_ref/c/func/CFUUIDCreateFromString
CFUUIDCreateFromString() appears to be the API you are looking for. Assuming that CFUUID is the "binary format" you are searching for.
If you then want "raw bytes", look at CFUUIDGetUUIDBytes()

I have a string that is "M456456" for example, and i need to keep only the numbers. So the ouput has to be "456456"
How can i achieve this in Kotlin?
"M456456".filter(Char::isDigit)
"M456456".filter {it in '0'..'9'}
Use a regex replacement and remove all non digit characters:
val regex = """[^0-9]""".toRegex()
val input = "M456456"
val output = regex.replace(input, "")
println(output) // 456456

As far I as my experience tells me, boolean variables usually named in format - is/has+noun/adj/verb, e.g isValid, isButton, hasClickedLink
But say there is the case where we have some flag which straightly tells whether to do something, like for example, clean to indicate that cleanup function should be automatically called in the end.
How to name such a booleans? Same clean - is ambiguous, looks like a method name more, but naming it toClean is, I don't know, too weird. Or should I name it like callCleanup?
Thanks in advance!
In this case i usually append the word wanted, which makes cleanWanted. In general, for boolean variables I also prefer to always let the last word be an adjective. This makes it very clear that it represents a truth value. The is/has prefix is often superfluous, as in hasClickedLink which is more concisely communicated with linkClicked.
methods are usually one word adjectives with a capitol at the start
maybe create a method that sets the flag
for example
void Clean(){
clean = True;
}

In Silicon Valley S03E01 Gilfoyle and Dinesh have a conversation about Richard. In the conversation they use the term dictionary patch as such:
Gilfoyle: What if we use like a dictionary patch? To compress all the
nice-guy stuff.
Dinesh: Like an acronym.
Gilfoyle: Exactly. "Richard is great, but you know"... R-I-G-B-Y.
Dinesh: Rigby.
Gilfoyle: Rigby is all the nice-guy stuff.
Wouldn't that be a dictionary key?
Example of a dictionary key:
var dictionary:Dictionary = new Dictionary();
dictionary["RIGBY"] = "Richard is great, but you know";
console.log(dictionary["RIGBY"]);
// output is "Richard is great, but you know";
in this case the dictionary key is "RIGBY"
http://siliconvalleyism.com/silicon-valley-quote.php?id=135
I've never heard of the term "dictionary patch" outside of Silicon Valley. But, yes, 'RIGBY' would be the dictionary key, but dictionary patch wasn't just talking about the key. They were referring to a process of using a dictionary key to replace a long value with that key. So, he's calling this whole higher-level process "dictionary patching", although I've never heard of it.

Assuming sngX = 67521.345, What will be displayed when the line of code:
Label1.Text = FormatCurrency(sngX)
is executed.
Assuming that your system regional settings currency sign is $, leading digits is false, and digit grouping is false, then FormatCurrency(67521.345) = $67,521.35
Since you haven't specified your regional settings, and haven't said that you want to use specific values for the other FormatCurrency parameters, your results may vary.

I have a method to perform some operation with block (let's say database transaction) with 4 vary conditions (2 boolean parameters). Well in many conventions including Apple's, the block parameter should be the last one but we should not put the bool parameter at first too.
What do you think I should name this method?
- (void)performDatabaseTransactionWithSynchronously:(BOOL)synchronously
isWritterOperation:(BOOL)isWritter
transaction:(TransactionBlock)block
or
- (void)performDatabaseTransactionWithSynchronously:(BOOL)synchronously
isWritterOperation:(BOOL)isWritter
withTransaction:(TransactionBlock)block
or
- (void)performDatabaseTransaction:(TransactionBlock)block
synchronously:(BOOL)synchronously
isWritterOperation:(BOOL)isWritter
Or any others?
My version is:
- (void)performDatabaseTransactionSynchronously:(BOOL)synchronously
isWriterOperation:(BOOL)isWriter
withBlock:(TransactionBlock)block
Now I used
- (BOOL)performDatabaseTransactionWithDeffered:(BOOL)useDeferred
isWriterOperation:(BOOL)isWritter
error:(NSError * __autoreleasing *)error
usingBlock:(TransactionBlock)block
and
- (void)performDatabaseTransactionAsynchronouslyWithDeffered:(BOOL)useDeferred
isWriterOperation:(BOOL)isWriter
transaction:(TransactionBlock)block
completion:(CompletionBlock)completion
Any other answer?
