• Help me sort programing languages a bit

  - by b-gen-jack-o-neill

  Hi, so I asked here few days ago about C# and its principles. Now, if I may, I have some additional general questions about some languages, becouse for novice like me, it seems a bit confusing. To be exact I want to ask more about language functions capabilities than syntax and so. To be honest, its just these special functions that bothers me and make me so confused. For exmaple, C has its printf(), Pascal has writeln() and so. I know in basic the output in assembler of these funtions would be similiar, every language has more or less its special functions. For console output, for file manipulation, etc. But all these functions are de-facto part of its OS API, so why is for example in C distinguished between C standard library functions and (on Windows) WinAPI functions when even printf() has to use some Windows feature, call some of its function to actually show desired text on console window, becouse the actuall "showing" is done by OS. Where is the line between language functions and system API? Now languages I dont quite understand - Python, Ruby and similiar. To be more specific, I know they are similiar to java and C# in term they are compiled into bytecode. But, I do not unerstand what are its capabilities in term of building GUI applications. I saw tutorial for using Ruby to program GUI applications on Linux and Windows. But isn´t that just some kind of upgrade? I mean fram other tutorials It seemed like these languages was first intended for small scripts than building big applications. I hope you understand why I am confused. If you do, please help me sort it out a bit, I have no one to ask.

• How to keep track of call statistics? C++

  - by tf.rz

  I'm working on a project that delivers statistics to the user. I created a class called Dog, And it has several functions. Speak, woof, run, fetch, etc. I want to have a function that spits out how many times each function has been called. I'm also interested in the constructor calls and destructor calls as well. I have a header file which defines all the functions, then a separate .cc file that implements them. My question is, is there a way to keep track of how many times each function is called? I have a function called print that will fetch the "statistics" and then output them to standard output. I was considering using static integers as part of the class itself, declaring several integers to keep track of those things. I know the compiler will create a copy of the integer and initialize it to a minimum value, and then I'll increment the integers in the .cc functions. I also thought about having static integers as a global variable in the .cc. Which way is easier? Or is there a better way to do this? Any help is greatly appreciated!

• How can I ignore the block content reading in Perl.

  - by Nano HE

  Hello. I plan to ignore the block content which include the start line of "MaterializeU4()" with the subroutin() read_block below. But failed. # Read a constant definition block from a file handle. # void return when there is no data left in the file. # Otherwise return an array ref containing lines to in the block. sub read_block { my $fh = shift; my @lines; my $block_started = 0; while( my $line = <$fh> ) { # how to correct my code below? I don't need the 2nd block content. $block_started++ if ( ($line =~ /^(status)/) && (index($line, "MaterializeU4") != 0) ) ; if( $block_started ) { last if $line =~ /^\s*$/; push @lines, $line; } } return \@lines if @lines; return; } Data as below: __DATA__ status DynTest = <dynamic 100> vid = 10002 name = "DynTest" units = "" status VIDNAME9000 = <U4 MaterializeU4()> vid = 9000 name = "VIDNAME9000" units = "degC" status DynTest = <U1 100> vid = 100 name = "Hello" units = "" Output: <StatusVariables> <SVID logicalName="DynTest" type="L" value="100" vid="10002" name="DynTest" units=""></SVID> <SVID logicalName="VIDNAME9000" type="L" value="MaterializeU4()" vid="9000" name="VIDNAME9000" units="degC"></SVID> <SVID logicalName="DynTest" type="L" value="100" vid="100" name="Hello" units=""></SVID> </StatusVariables> [Updated] I print the value of index($line, "MaterializeU4"), it output 25. Then I updated the code as below $block_started++ if ( ($line =~ /^(status)/) && (index($line, "MaterializeU4") != 25) Now it works. Any comments are welcome about my practice. Thank you.

• How to display full documentation of a method as you type in VS?

  - by drasto

  The title is pretty descriptive... Is there any extension that let me see FULL documentation of the method I'm typing ? I would like to see the documentation as I can see it in Object Browser with description of parameters and everything not just some "summary". So what I'd like to see when I type String.Format is: Of cause with an option to see all overrides. It may be part of intelisence or I don't know what it does not really matter.

• How can I create an Assembly program WITHOUT using libraries?

  - by Newbie

  Hello. I've literally only just started looking to learn Assembly language. I'm using the NASM assembler on Windows Vista. Usually, when I begin to learn a new language, I'll copy someone else's Hello World code and try to understand it line-by-line. However, I'm finding it suprisingy difficult to find a Hello World program that doesn't reference other libraries! You see, there's no point trying to understand each line of the code if it is closely linked with a whole library of additional code! One of the reasons I want to learn Assembly is so that I can have near complete control over the programs I write. I don't want to be depending on any libraries. And so my question is this: Can anyone give me NASM-compatible Assembly code to a completely stand-alone Hello World program that can output to the Windows Vista console? Alternatively, I appreciate that a library may be required to tell the pogram WHERE to print the output (ie. the Windows console). Other than that, I can't see why any libraries should be required. Am I overlooking anything?

• C++ string.substr() function problem

  - by VaioIsBorn

  I want to make a program that will read some number in string format and output it like this: if the number is 12345 it should then output 12 23 34 45 . I tried using the substr() function from the c++ string library, but it gives me strange results - it outputs 1 23 345 45 instead of the expected result. Why ? #include <iostream> #include <string> #include <cstdlib> using namespace std; int main(void) { string a;cin >> a; string b;int c; for(int i=0;i<a.size()-1;++i) { b = a.substr(i,i+1); c = atoi(b.c_str()); cout << c << " "; } cout << endl; return 0; }

• Qt XQuery into a QStringList

  - by Stewart

  Hi, I'm trying to use QtXmlQuery to extract some data from XML. I'd like to put this into a QStringList. I try the following: QByteArray in = "this is where my xml lives"; QBuffer received; received.setData(in); received.open(QIODevice::ReadOnly); QXmlQuery query; query.bindVariable("data", &received); query.setQuery(NAMESPACE //contains definition of the t namespace "doc($data)//t:service/t:serviceID/text()"); QBuffer outb; outb.open(QIODevice::ReadWrite); QXmlSerializer s(query, &outb); query.evaluateTo(&s); qDebug() << "buffer" << outb.data(); //This works perfectly! QStringList * queryResult = new QStringList(); query.evaluateTo(queryResult); qDebug() << "string list" << *queryResult; //This gives me no output! As you can see, everything works fine when I send the output into a QBuffer via a QXmlSerializer... but I get nothing when I try to use a QStringList.

• How do you make an added row from QueryAddRow() the first row of the result from a query?

  - by JS

  I am outputting a query but need to specify the first row of the result. I am adding the row with QueryAddRow() and setting the values with QuerySetCell(). I can create the row fine, I can add the content to that row fine. If I leave the argument for the row number off of QuerySetCell() then it all works great as the last result of the query when output. However, I need it to be first row of the query but when I try to set the row attribute with the QuerySetCell it just overwrites the first returned row from my query (i.e. my QueryAddRow() replaces the first record from my query). What I currently have is setting a variable from recordCount and arranging the output but there has to be a really simple way to do this that I am just not getting. This code sets the row value to 1 but overwrites the first returned row from the query. <cfquery name="qxLookup" datasource="#application.datasource#"> SELECT xID, xName, execution FROM table </cfquery> <cfset QueryAddRow(qxLookup)/> <cfset QuerySetCell(qxLookup, "xID","0",1)/> <cfset QuerySetCell(qxLookup, "xName","Delete",1)/> <cfset QuerySetCell(qxLookup, "execution", "Select this to delete",1)/> <cfoutput query="qxLookup"> <tr> <td> <a href="##" onclick="javascript:ColdFusion.navigate('xSelect/x.cfm?xNameVar=#url.xNameVar#&xID=#qxLookup.xID#&xName=#URLEncodedFormat(qxLookup.xName)#', '#xNameVar#');ColdFusion.Window.hide('#url.window#')">#qxLookup.xName#</a> </td> <td>#qxLookup.execution#</td> </tr> </cfoutput> </table> Thanks for any help.

• model.matrix() with na.action=NULL?

  - by Vincent

  I have a formula and a data frame, and I want to extract the model.matrix(). However, I need the resulting matrix to include the NAs that were found in the original dataset. If I were to use model.frame() to do this, I would simply pass it na.action=NULL. However, the output I need is of the model.matrix() format. Specifically, I need only the right-hand side variables, I need the output to be a matrix (not a data frame), and I need factors to be converted to a series of dummy variables. I'm sure I could hack something together using loops or something, but I was wondering if anyone could suggest a cleaner and more efficient workaround. Thanks a lot for your time! And here's an example: dat <- data.frame(matrix(rnorm(20),5,4), gl(5,2)) dat[3,5] <- NA names(dat) <- c(letters[1:4], 'fact') ff <- a ~ b + fact # This omits the row with a missing observation on the factor model.matrix(ff, dat) # This keeps the NA, but it gives me a data frame and does not dichotomize the factor model.frame(ff, dat, na.action=NULL) Here is what I would like to obtain: (Intercept) b fact2 fact3 fact4 fact5 1 1 0.7266086 0 0 0 0 2 1 -0.6088697 0 0 0 0 3 NA 0.4643360 NA NA NA NA 4 1 -1.1666248 1 0 0 0 5 1 -0.7577394 0 1 0 0 6 1 0.7266086 0 1 0 0 7 1 -0.6088697 0 0 1 0 8 1 0.4643360 0 0 1 0 9 1 -1.1666248 0 0 0 1 10 1 -0.7577394 0 0 0 1

• C++ STL question related to insert iterators and sets

  - by rshepherd

  #include #include #include #include using namespace std; class MyContainer { public: string value; MyContainer& operator=(const string& s) { this->value = s; return *this; } }; int main() { list<string> strings; strings.push_back("0"); strings.push_back("1"); strings.push_back("2"); set<MyContainer> containers; copy(strings.begin(), strings.end(), inserter(containers, containers.end())); } The preceeding code does not compile. In typical STL style the error output is verbose and difficult to understand. The key part seems to be this... /usr/include/c++/4.4/bits/stl_algobase.h:313: error: no match for ‘operator=’ in ‘__result.std::insert_iterator::operator* [with _Container = std::set, std::allocator ]() = __first.std::_List_iterator::operator* [with _Tp = std::basic_string, std::allocator ]()’ ...which I interpet to mean that the assignment operator needed is not defined. I took a look at the source code for insert_iterator and noted that it has overloaded the assignment operator. The copy algorithm must uses the insert iterators overloaded assignment operator to do its work(?). I guess that because my input iterator is on a container of strings and my output iterator is on a container of MyContainers that the overloaded insert_iterator assignment operator can no longer work. This is my best guess, but I am probably wrong. So, why exactly does this not work and how can I accomplish what I am trying to do?

• Ruby: Efficiently check if a hash's keys include all elements of an Array.

  - by Jason

  I want to compare the keys in a hash of parameters against an array of elements for a match. For example: params = {"key1", "key2", "key3"} params_to_match = ["key2","key3"] I could do this, but I'm sure there is a much more elegant way to acheive the same result params.each_key{|key| if params_to_match.include?(key.to_s) return end }

• Replace beginning words(SQL SERVER 2005, SET BASED)

  - by Newbie

  I have the below tables. tblInput Id WordPosition Words -- ----------- ----- 1 1 Hi 1 2 How 1 3 are 1 4 you 2 1 Ok 2 2 This 2 3 is 2 4 me tblReplacement Id ReplacementWords --- ---------------- 1 Hi 2 are 3 Ok 4 This The tblInput holds the list of words while the tblReplacement hold the words that we need to search in the tblInput and if a match is found then we need to replace those. But the problem is that, we need to replace those words if any match is found at the beginning. i.e. in the tblInput, in case of ID 1, the words that will be replaced is only 'Hi' and not 'are' since before 'are', 'How' is there and it is not in the tblReplacement list. in case of Id 2, the words that will be replaced are 'Ok' & 'This'. Since these both words are present in the tblReplacement table and after the first word i.e. 'Ok' is replaced, the second word which is 'This' here comes first in the list of ID category 2 . Since it is available in the tblReplacement, and is the first word now, so this will also be replaced. So the desired output will be Id NewWordsAfterReplacement --- ------------------------ 1 How 1 are 1 you 2 is 2 me My approach so far: ;With Cte1 As( Select t1.Id ,t1.Words ,t2.ReplacementWords From tblInput t1 Cross Join tblReplacement t2) ,Cte2 As( Select Id, NewWordsAfterReplacement = REPLACE(Words,ReplacementWords,'') From Cte1) Select * from Cte2 where NewWordsAfterReplacement <> '' But I am not getting the desired output. It is replacing all the matching words. Urgent help needed*.( SET BASED )* I am using SQL SERVER 2005. Thanks

• Synfony2 validation changes invalid integer to 0

  - by Craig

  I've added validation to a form and found that in some cases it is losing the invalid data I am feeding it and saving 0s instead. The output at the bottom shows that if I post the latitude as 'zzzzzz' (clearly not a number nor between -90 and 90) the form is declared as valid and saved with the value 0 How can that happen given that I have declared the input must be a number? ProxyType.php buildForm() $builder ->add('siteName', null, array('label' => 'Site name')) .... ->add('latitude', 'number', array('label' => 'Latitude')) ->add('longitude', 'number', array('label' => 'Longitude')) .... ; ProxyController.php createAction .... $postData = $request->request->get('niwa_pictbundle_proxytype'); $this->get('logger')->info('Posted latitude = '.$postData['latitude']); $form = $this->createForm(new ProxyType(), $entity); $form->bindRequest($request); if ($form->isValid()) { $this->get('logger')->info('Form declared valid : latlong ('.$entity->getLatitude().','.$entity->getLongitude().')'); .... validation.yml Acme\PictBundle\Entity\Proxy: properties: longitude: - Min: { limit: -180 } - Max: { limit: 180 } latitude: - Max: { limit: 90 } - Min: { limit: -90 } Output [2012-09-28 02:05:30] app.INFO: Posted latitude = zzzzzz [] [] [2012-09-28 02:05:30] app.INFO: Form declared valid : latlong (0,0) [] []

• span,div ,p element. What should I use and how?

  - by Cesar Lopez

  I have the following problem. I have a td which I need to add other three elements inside (span,div,p, or any other suggestion) in order to align the three elements inside one next to each other (the content of this elements is text). If all the elements contains a single line of text, then everything its fine. The problem comes when the first to are single line of text and third element contains more than one line of text, then text of third element it would go under first element, but I need it to go under third element. eg. Output desired. Title on element1: (subtitle on element 2) Text on element 3 with several lines of text. Actual output. Title on element1: (subtitle on element 2) Text on element 3 with several lines of text. html code sample <td> <span display="inline">Title on element1:</span> <span display="inline">(subtitle on element 2)</span> <span display="inline">Text on element 3 <br/> with several lines <br/> of text.</span> </td>
