  • Reuse ASP.NET Control Multiple Times on Page

    - by macinjosh
    I feel somewhat foolish asking such a simple question, but I can't seem to find an answer. I'm new to ASP.NET (C#), but I'm learning by building a simple set of web pages that display a report. I have a variable that represents a company name. I need to output this variable in multiple places on the web page. The only way I have found to output a variable this is with: company_name.Text = "Acme Windows"; then <asp:literal id="company_name" runat="server" /> My problem is that I want to use company_name in multiple places on the page. Do I really have to create a separate variable holding the the same value for each time it is placed on the page? If I just copy the above XML code to all the places I want to show the variable it obviously creates a compile error since that ID is already defined. I feel like I'm missing something very obvious.

  • Pig: Count number of keys in a map

    - by Donald Miner
    I'd like to count the number of keys in a map in Pig. I could write a UDF to do this, but I was hoping there would be an easier way. data = LOAD 'hbase://MARS1' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage( 'A:*', '-loadKey true -caching=100000') AS (id:bytearray, A_map:map[]); In the code above, I want to basically build a histogram of id and how many items in column family A that key has. In hoping, I tried c = FOREACH data GENERATE id, COUNT(A_map); but that unsurprisingly didn't work. Or, perhaps someone can suggest a better way to do this entirely. If I can't figure this out soon I'll just write a Java MapReduce job or a Pig UDF.

  • Constants by another name

    - by Dave DeLong
    First off, I've seen this question and understand why the following code doesn't work. That is not my question. I have a constant, which is declared like; //Constants.h extern NSString * const MyConstant; //Constants.m NSString * const MyConstant = @"MyConstant"; However, in certain contexts, it's more useful to have this constant have a much more descriptive name, like MyReallySpecificConstant. I was hoping to do: //SpecificConstants.h extern NSString * const MyReallySpecificConstant; //SpecificConstants.m #import "Constants.h" NSString * const MyReallySpecificConstant = MyConstant; Obviously I cannot do this (which is explained in the linked question above). My question is: How else (besides something like #define MyReallySpecificConstant MyConstant) can I provide a single constant under multiple names?

  • Formatting a string in Java using class attributes

    - by Jason R. Coombs
    I have a class with an attribute and getter method: public Class MyClass { private String myValue = "foo"; public String getMyValue(); } I would like to be able to use the value of foo in a formatted string as such: String someString = "Your value is {myValue}." String result = Formatter.format(someString, new MyClass()); // result is now "Your value is foo." That is, I would like to have some function like .format above which takes a format string specifying properties on some object, and an instance with those properties, and formats the string accordingly. Is it possible to do accomplish this feat in Java?

  • free switch : what is tls_port ?

    - by kiruthika
    Hi all, I am beginner to free switch.I have gone through the configuration file vars.xml in free switch. In this I have seen the following configurations. <X-PRE-PROCESS cmd="set" data="internal_auth_calls=true"/> <X-PRE-PROCESS cmd="set" data="internal_sip_port=5070"/> <X-PRE-PROCESS cmd="set" data="internal_tls_port=5071"/> <X-PRE-PROCESS cmd="set" data="internal_ssl_enable=false"/> <X-PRE-PROCESS cmd="set" data="internal_ssl_dir=$${base_dir}/conf/ssl"/> In the above I am having the doubt with tls_port. What is the use of tls_port .I have searched about this in net and I have read that tls protocol is used for secure data transfer in network. So please explain me about the communication in freeswitch. Thanks in advance.

  • Python: Trying to get index of an intersection

    - by user1620716
    I have the following line of code: for i in [i for i,x in enumerate(catdate) if x == set(NNSRCfile['datetimenew']).intersection(catdate)]: print i I am trying to find the index of the intersection for the two components above. Both are lengthy lists that have several commonalities. The intersection part works perfectly; however, the for loop seems to output nothing. (ie: there is nothing that is printed). Python outputs no error, and when I run the code in IPython, I notice that i is equivalent to to the very last element in the list "catdate", instead of listing the indices of "catdate" that are equivalent to the intersection values. Any help is greatly appreciated!

  • How to access fields in JSON object by index

    - by Stefan
    I know this isn't the best way to do it, but I have no other choice :( I have to access the items in JSONObject by their index. The standard way to access objects is to just wirte this[objectName] or this.objectName. I also found a method to get all the fields inside a json object: (for (var key in p) { if (p.hasOwnProperty(key)) { alert(key + " -> " + p[key]); } } (Soruce : Loop through Json object). However there is no way of accessing the JSONfields directly by a index. The only way I see right now, is to create an array, with the function above, get the fieldname by index and then get the value by fieldname. As far as I see it, the p (in our case the JSON file must be an iteratable array to, or else the foreach loop wouldn't work. How can I access this array directly? Or is it some kind of unsorted list? Regards, Stefan

  • Avoiding nesting two for loops

    - by chavanak
    Hi, Please have a look at the code below: import string from collections import defaultdict first_complex=open( "residue_a_chain_a_b_backup.txt", "r" ) first_complex_lines=first_complex.readlines() first_complex_lines=map( string.strip, first_complex_lines ) first_complex.close() second_complex=open( "residue_a_chain_a_c_backup.txt", "r" ) second_complex_lines=second_complex.readlines() second_complex_lines=map( string.strip, second_complex_lines ) second_complex.close() list_1=[] list_2=[] for x in first_complex_lines: if x[0]!="d": list_1.append( x ) for y in second_complex_lines: if y[0]!="d": list_2.append( y ) j=0 list_3=[] list_4=[] for a in list_1: pass for b in list_2: pass if a==b: list_3.append( a ) kvmap=defaultdict( int ) for k in list_3: kvmap[k]+=1 print kvmap Normally I use izip or izip_longest to club two for loops, but this time the length of the files are different. I don't want a None entry. If I use the above method, the run time becomes incremental and useless. How am I supposed to get the two for loops going? Cheers, Chavanak

  • How to get fopen to timeout properly

    - by beagleguy
    hey all, I have the following snippet of php code if($fp = fopen($url, 'r')) { stream_set_timeout($fp, 1); stream_set_blocking($fp, 0); } $info = stream_get_meta_data($fp); I'd like the request to timeout after 1 second... if I put a sleep(20) in my $url that I'm reading it just waits the whole 20 seconds and never times out. Is there a better way to do timeouts with fopen? If I use ini_set('default_socket_timeout',2); above that code it times out properly but $info then becomes null so ideally I'd like to use the stream functions. thanks

  • simile exhibit ie7 bug

    - by two7s_clash
    'm using to Exhibit to, pretty simply, display some data on historical events and book publication dates: http://f1shw1ck.com/timeline3/exhibit.html Everything works fine, and I have been able to get the timeline running as wanted, until I try to take control of the timeline with a timelineConfig script. After I add this, my timeline continues to work as expected on all browsers, except for IE. Curiously enough, band 0 initializes and is rendered correctly, but band 1 shows no events and does not sync to the band above. But it is picking up the width: 10%", intervalUnit: Timeline.DateTime.DECADE, intervalPixels: 60 specifications, as they are rendered correctly. Since everything works until I call ex:configuration="timelineConfig", since everything works in the other browsers, and since everything almost works in IE, up to the event painting, I have to imagine this is a javascript coding error on my part, but I just can't see it. All I get in my console is Failed to create view View As Timeline." Incidentally, having or not having the gotoYear function seemingly does nothing to change... Thanks for any tips.

  • Objective-C: Protocols

    - by Stu
    I'd like an instance variable object to adopt a protocol. @interface GameScene : Scene <AVAudioPlayerDelegate> { @private Layer *content <CocosNodeOpacity>; } For example I'd like my Layer object to adopt the <CocosNodeOpacity> so that I can get the methods -(GLubyte) opacity; //and -(void) setOpacity: (GLubyte) opacity; for free. The syntax shown above is invalid. Is it possible to achieve this without creating a new implementation file and creating a custom object? Thanks.

  • C: Expanding an array with malloc

    - by Mal Ock
    I'm a bit new to malloc and C in general. I wanted to know how I can, if needed, extend the size of an otherwise fixed-size array with malloc. Example: #define SIZE 1000 struct mystruct { int a; int b; char c; }; mystruct myarray[ SIZE ]; int myarrayMaxSize = SIZE; .... if ( i > myarrayMaxSize ) { // malloc another SIZE (1000) elements myarrayMaxSize += SIZE; } The above example should make clear what I want to accomplish. (By the way: I need this for an interpreter I write: Work with a fixed amount of variables and in case more are needed, just allocate them dynamically)

  • How can the javascript plugin architecture in raphael/jquery be done?

    - by TimDog
    I'm looking for a barebones javascript example that demonstrates how the javascript plugin architecture works with large javascript libraries (such as raphael or jquery). In either scenario, you build plugins by ensuring your custom plugin follows this pattern: jQuery.fn.pluginName -- so assume I have a library: myLibrary = (function() { //my fancy javascript code return function() { //my return object }; }); How would fn be incorporated into the above myLibrary object to ensure that he resulting plugin is callable? I instantiate myLibrary like so: var lib = new myLibrary(); And now I have included a reference to my plugin in my page: myLibrary.fn.simplePlugin = function() { //more fancy code } So finally, I can just call: lib.simplePlugin(); Basically, what magic is actually occuring when the .fn is used during the creation of the plugin?

  • Bash: using commands as parameters (specifically cd, dirname and find)

    - by sixtyfootersdude
    This command and output: % find . -name file.xml 2> /dev/null ./a/d/file.xml % So this command and output: % dirname `find . -name file.xml 2> /dev/null` ./a/d % So you would expect that this command: % cd `dirname `find . -name file.xml 2> /dev/null`` Would change the current directory to ./a/d. Strangely this does not work. When I type cd ./a/d. The directory change works. However I cannot find out why the above does not work...

  • rake task can't access rails.cache

    - by mark
    Hi I want to call a rake task from a cron job that stores remote weather data in the rails cache. However, I must be doing something pretty wrong here because I cannot find any solution through countless fruitless searches. Say I define and call this task namespace :weather do desc "Store weather from remote source to cache" task :cache do Rails.cache.write('weather_data', Date.today) end end I get the error Anonymous modules have no name to be referenced by Which leads me to believe the rails cache isn't available. Outputting Rails.class from the rake file gives me Module but Rails.cache.class again returns the above error. Do I need to include something here? Am I just hopeless at internet? :) Thanks in advance.

    var records = JSON.parse(JsonString); for(var x=0;x<records.result.length;x++) { var record = records.result[x]; ht_text+="<b><p>"+(x+1)+" " +record.EMPID+" " +record.LOCNAME+" " +record.DEPTNAME+" " +record.CUSTNAME +"<br/><br/><div class='slide'>" +record.REPORT +"</div></p></b><br/>"; } The above code works fine when the JsonString contains an array of entities but fails for single entity. result is not identified as an array! Whats wrong with it? http://pastebin.com/hgyWw5hd

  • Peak decomposition

    - by midtiby
    Hi I want to examine a NMR spectre and make the best fit of a specific peak using a sum of gaussians. With the following code it is possible to fit two gaussians to the peak, but can it easily be generalized to n gaussians? freq <- seq(100, 200, 0.1) signal <- 3.5*exp(-(freq-130)^2/50) + 0.2 + 1.5*exp(-(freq-120)^2/10) simsignal <- rpois(length(signal), 100*signal) + rnorm(length(signal)) plot(freq, simsignal) res <- nls(simsignal ~ bg + h1 * exp(-((freq - m1)/s1)^2) + h2 * exp(-((freq - m2)/s2)^2), start=c(bg = 4, h1 = 300, m1 = 128, s1 = 6, h2 = 200, m2 = 122, s2 = 4), trace=T) lines(freq, predict(res, freq), col='red') Another wish is a visulization of the contribution from each of the gaussians to the original peak, eg. the gaussians should be plotted side by side (instead of plotting their sum as done above).

  • MVC Application Design

    - by Paul Brown
    Hello I am about to create my first proper application in ASP.NET MVC3. It is basically a jobs site with 3 levels: 1) Users - No registration and can view all jobs posted on the website 2) Posters - Need to register and login to post adverts 3) Admin - Need to register and login to post adverts and review postings before they go live Would you suggest I use the same Jobs controller for the three levels I mention above? With a LIST action to show jobs to "Users" and a CREATE & EDIT action for the "Posters" & "Admin"? Thanks Paul

  • How Do I Programmatically Check if a WordPress Plugin Is Already Activated?

    - by Volomike
    I know I can use activate_plugin() from inside a given, active plugin in WordPress, to activate another plugin. But what I want to know is how do I programmatically check if that plugin is already active? For instance, this snippet of code can be temporarily added to an existing plugin's initial file to activate a partner plugin: add_action('wp','activatePlugins'); function activatePlugins() { if( is_single() || is_page() || is_home() || is_archive() || is_category() || is_tag()) { @ activate_plugin('../mypartnerplugin/thepluginsmainfile.php'); } } Then, use a Linux command line tool to spider all your sites that have this code, and it will force a page view. That page view will cause the above code to fire and activate that other plugin. That's how to programmatically activate another plugin from a given plugin as far as I can tell. But the problem is that it gets activated over and over and over again. What would be great is if I had an if/then condition and some function I could call in WordPress to see if that plugin is already activated, and only activate it once if not active.

  • Is this code well-defined?

    - by Nawaz
    This code is taken from a discussion going on here. someInstance.Fun(++k).Gun(10).Sun(k).Tun(); Is this code well-defined? Is ++k Fun() evaluated before k in Sun()? What if k is user-defined type, not built-in type? And in what ways the above function calls order is different from this: eat(++k);drink(10);sleep(k); As far as I can say, in both situations, there exists a sequence point after each function call. If so, then why can't the first case is also well-defined like the second one? Section 1.9.17 of the C++ ISO standard says this about sequence points and function evaluation: When calling a function (whether or not the function is inline), there is a sequence point after the evaluation of all function arguments (if any) which takes place before execution of any expressions or statements in the function body. There is also a sequence point after the copying of a returned value and before the execution of any expressions outside the function.

  • Win32 select/poll/eof/ANYTHING!?!?!

    - by Andrew
    Using the standard Win32 file I/O API's (CreateFile/ReadFile/etc), I'm trying to wait for a file to become readable, or for an exception to occur on the file. If Windows had any decent POSIX support, I could just do: select(file_count, files_waiting_for_read, NULL, files_waiting_for_excpt, NULL, NULL); And select will return when there's anything interesting on some of the files. Windows doesn't support select or poll. Fine. I figured I could take the file and do something like: while(eof(file_descriptor)) { Sleep(100); } The above loop would exit when more data is available to be read. But nope, Windows doesn't have an equivalent of eof() either! I could possibly call ReadFile() on the file, and determine if it's at the eof that way. But, then I'd have to handle the reading at that point in time -- I'm hoping to simply be able to figure out that a file is readable, without actually reading it. What are my options?

  • Freebase Query with "JOINS"

    - by codemonkey
    ... Yeah, yeah, I know traditional joins don't exist. I actually like the freebase query methodology in theory, just having a little trouble getting it to actually work for me : ) Anyone have a dumb-simple example of getting Freebase data via MQL that pulls from two different "tables"? In particular, I'm trying to get automotive data... so for example, pulling fields from both /automotive/model_year and /automotive/trim_year. I've read the documentation (for hours actually). There's a distinct possibility that I'm looking right at such an example somewhere and just not seeing it because my OLTP brain just doesn't comprehend what it's seeing. * Note * ... that the two "types" I'm working with above are siblings, not parent/child. Does freebase even allow joining data between sibling nodes... I see examples of queries pulling from parent/child, but not from siblings I don't think (or I've overlooked them).

  • js regex replace multiple words

    - by Raghav
    I need to replace ${conferance name} with ABC, ${conference day} with Monday in the following sentence. Could some one help me with the regex. var text = "<td>${conference name}</td><td>${conference day}</td>" var list = ["${conferance name}", "${conference day}" ] for (var j = 1; j < list.length; j++) { //Extracting the col name var colName = list[j].split("${"); colName = colName.split("}")[0]; //Replacing the col name text = text.replace(new RegExp('\\$\\{' + colName + '\\}', 'g'), "ABC"); } The above code repalces fine if i have ${conference_name}, but it fails when i have a space in between. The list is a dynamic array. And the Replace statements are also dynamic. I just simulated them as objects here for fitting them in the Regex Statement. Thanks in Advance.
