What is an index in table? Related with realworld entitly like librabry.
what are the types of indexes? please related this too also with real world entity.
I've been using the following:
var modal = {
content: '',
form: '',
href: ''
}
But now I have started to use Typescript is there a better way I can declare an object and how can I declare the types of my properties. The reason I am using this object is that it's inside of a function and inside that function I have other functions that set and use the values of the properties. Is this the best way for me to do this or is there another way I could better do this with typescript?
The difference between Chr and Char when used in converting types is that one is a function and the other is cast
So: Char(66) = Chr(66)
I don't think there is any performance difference (at least I've never noticed any, one probably calls the other).... I'm fairly sure someone will correct me on this!
Which do you use in your code and why?
Hey there,
Recently I ran into a very strange issue: touching the screen of the iPhone and moving a finger around can eat up to 50% of my FPS. Yeah, I checked my code for possible bottlenecks – not the issue. The last resort I tried before writing this post – commenting out all the touch processing code and looking at FPS then. Results are: no touches – 58-60. Touching and moving the finger – 35-40 FPS instantly.
The rendering is done in a separate thread, so that no main runloop events shall collide with it. However, it's very crushial for me (and the game I develop) to resolve this issue, because such FPS drop is really noticeable.
Thank you for your help in advance.
UPDATE: seems that setting rendering thread's priority to higher value helps a bit...
I'm being asked to assess whether we can safely upgrade the java version on one of our production-deployed webapps. The codebase is fairly large and we want to avoid having to regression test everything (no automated tests sadly), but we've already encountered at least one problem during some manual testing (XmlStringReader.getLocalName now throws an IllegalStateExeption when it just used to return null) and higher-ups are pretty nervous about the upgrade.
The current suggested approach is to do a source compare of the JDK sources for each version and assess those changes to see which ones might have impact, but it seems there's a lot of changes to go through (and as mentioned the codebase is kinda large). Is it safe and easier to just review the java version changes for each version? Or is there an easier way to conduct this assessment?
Edit: I forgot to mention the version upgrade being considered is a minor version upgrade, i.e. 1.6.10 to 1.6.33
$ bc
BC> ibase=2
BC> 110&101 // wanna get 100
(standar_in) 8: syntax error
Wikipedia informs that the ops are "|, & and ^". It may be that they work only in certain BC-types or I misread something.
I want to use a field (kind of QTextEdit), which is capabale of storing picture and text (like MS Word is doing) and it serializes and deserialaizes picture+text data. Is there any Qt Widget that allows us to manipulate with picture and text simultaniously and it has set/get functions which operate with serializable type? In othger words, I want to know if there exsists any Qt widget that can store picture+text and has "get" types of function that returns the content of that widgets editable area, which is a Type that could be serialized with QDataStream.
Is there a way to "declare" a variable with a particular user-defined type in MATLAB? zeros() only works for built-in numeric types. The only solution I've come up with involves using repmat() to duplicate a dummy object zero times:
arr = repmat(myClass(), [1 0])
Without declaring variables this way, any code which does "arr(end+1) = myClass()" has to include a special case for the default empty matrix which is of type double.
Have I missed something a little more sensible?
I'd like to block all characters from being inputed except 0-9,a-z,A-Z range only alphanumeric characters. So when someone types ! for examplee nothing is written into input. How can I do that?
Our vendor-supported server's O/S only supports PHP 5.1.6, which limits us to ZF 1.6. The current version of Zend Framework requires a higher version of PHP.
We're struggling to decide whether to adopt ZF because of this incompatibility. Is it feasible to develop (indefinitely) in these older versions of ZF or should we hold off?
Features, security, bugs, etc. Is this a path we don't want to go down or are these older versions perfectly usable in a production environment?
What is the minimum set of primitives required such that a language is Turing complete and a lisp variant?
Seems like car, cdr and some flow control and something for REPL is enough. It be nice if there is such list.
Assume there are only 3 types of data, integers, symbols and lists.(like in picolisp)
I've heard/read about people not wanting to reference the assembly because of the Windows component (e.g. "I don't want to reference Windows for my Web App).
I'd like to hear what a large community feels about this.
For which project types (business, data access, etc.) is it considered acceptable to reference WindowsBase.dll.
What potential memory leaks won't an implicit destructor handle? I know that if you have anything stored on the heap it won't handle it, and if you have a connection to a file or a database, that needs to be handled manually. Is there anything else? What about, say, non-base data types like vectors?
Also, in an explicit destructor, need you destroy non-heap variables which would have been destroyed by the implicit, or are they handled automatically?
Thanks
When you ask for a new HierarchyID between two others, the result gets progressively longer. For example, between 2/5.6 and 2/5.7 there's only 2/5.6.1 and other 4 component paths. The HierarchyID data type is limited to 800 some bytes, so you can't repeat this forever. Then again, integer types are also limited, but it isn't a problem in practice. Should I periodically defragment my table so that height doesn't grow unbounded?
i have a problem which is that i want to extract information about FAT(file allocation table) in C# but the restriction is i cannot use System.IO
so How i get drive types?cluster information e.t.c
println args
println args.size()
println args.each{arg-> println arg}
println args.class
if (args.contains("Hello"))
println "Found Hello"
when ran give following error:
[hello, somethingelse]
2
hello
somethingelse
[hello, somethingelse]
class [Ljava.lang.String;
Caught: groovy.lang.MissingMethodException: No signature of method: [Ljava.lang.
String;.contains() is applicable for argument types: (java.lang.String) values:
[Hello]
why can I not do contains?
Hey guys,
i have a list of items containig names.
then i have a eventlistener, which ckecks for keypress event.
if the user types i.g. an A all names starting with an A should be viewed with the A bold. so all starting As should be bold.
what is the best way using jquery to highlite only a part of a string?
thanks for your help
I have list of urls of types:
http://www.abc.com/pk/etc
http://www.abc.com/pk/etc/
http://www.abc.com/pk/etc/etc
where etc can be anything.
So I want to search only those urls that contains www.abc.com/pk/etc or www.abc.com/pk/etc/
Friends,
Our JSP code uses both Spring form tags and JSTL tags. Is there a way that when I search for getFoo() in the Eclipse Java Search, for Eclipse to also return uses of the foo property in the JSP files?
I suspect the answer is "no", because there isn't a way at compile time to tell the types of the JSP beans, but its worth asking, right?
Hi:
Is there any alternative to non-ISO gcc specific extension __attribute__ on 64-bit kernels ?
Three types that i've noticed are: function attributes, type attributes and variable attributes.
eg.
i'd like to avoid using __attribute__((__packed__)) for structures passed over the network, even though some gcc based code do use it.
Any suggestions or pointers on how to entirely avoid __attribute__ usage in C systems/kernel code ?
thanks

For certain types of sql queries, an auxiliary table of numbers can be very useful. It may be created as a table with as many rows as you need for a particular task or as a user defined function that returns the number of rows required in each query.
What is the optimal way to create such a function?
I have a user profile property. user not assigned any value that property. If I use below code. It is thorwing exception " object reference not set to an instance of an object "
userprof["OptOut"].ToString()
I tried all types
like
if (userprof["OptOut"] != null)
OR
if(userprof["OptOut"].Value != null)
nothing worked out for me.
Here userProf object has value. userprof["OptOut"].Value is null
How to handle this?
how to get a Dictionary key by value in C#?
Dictionary<string, string> types = new Dictionary<string, string>()
{
{"1", "one"},
{"2", "two"},
{"3", "three"}
};
I want simething like this:
getByValueKey(string value);
getByValueKey("one") must be return "1".
What is the best way do this? may be HashTable, SortedLists?
Per MSDN, calling Type.GetMethods() stores reflected method information in a MemberInfo cache so the expensive operation doesn't have to be performed again.
I have an application that scans assemblies/types, looking for methods that match a given specification. The problem is that memory consumption increases significantly (especially with large numbers of referenced assemblies) since .NET hangs onto the method metadata.
Is there any way to clear or disable this MemberInfo cache?
