  • I can I separate multiple logical pages in a text file I create in Perl?

    - by Micah
    So far, I've been successful with generating output to individual files by opening a file for output as part of outer loop and closing it after all output is written. I had used a counting variable ($x) and appended .txt onto it to create a filename, and had written it to the same directory as my perl script. I want to step the code up a bit, prompt for a file name from the user, open that file once and only once, and write my output one "printed letter" per page. Is this possible in plain text? From what I understand, chr(12) is an ascii line feed character and will get me close to what I want, but is there a better way? Thanks in advance, guys. :) sub PersonalizeLetters{ print "\n\n Beginning finalization of letters..."; print "\n\n I need a filename to save these letters to."; print "\n Filename > "; $OutFileName = <stdin>; chomp ($OutFileName); open(OutFile, ">$OutFileName"); for ($x=0; $x<$NumRecords; $x++){ $xIndex = (6 * $x); $clTitle = @ClientAoA[$xIndex]; $clName = @ClientAoA[$xIndex+1]; #I use this 6x multiplier because my records have 6 elements. #For this routine I'm only interested in name and title. #Reset OutLetter array #Midletter has other merged fields that aren't specific to who's receiving the letter. @OutLetter = @MiddleLetter; for ($y=0; $y<=$ifLength; $y++){ #Step through line by line and insert the name. $WorkLine = @OutLetter[$y]; $WorkLine =~ s/\[ClientTitle\]/$clTitle/; $WorkLine =~ s/\[ClientName\]/$clName/; @OutLetter[$y] = $WorkLine; } print OutFile "@OutLetter"; #Will chr(12) work here, or is there something better? print OutFile chr(12); $StatusX = $x+1; print "Writing output $StatusX of $NumRecords... \n\n"; } close(OutFile); }

  • Custom QAction/QMenu for mouse button detection

    - by voodoogiant
    I'm trying to create a popup menu, where I can detect the mouse button that was pressed for a given item. I've created a custom QAction already to build my QMenu, but the triggered signal when the menu item is pressed doesn't provide a QMouseEvent for me to query the button pressed. Also, I'm setting the a status tip for each QAction, which appears in the status bar when I mouse over it, but it stays even after I close the QMenu. Is this normal behavior?

  • Javascript click function for multiple Classes

    - by Jason Bassett
    So basically I have this little social networking site which allow comments. I've built a comment section that will slide down once a user clicks "Comment" and it slides down under the users status. My problem is that right now, the JavaScript only works on ONE post ID, and not the rest obviously seeing you can only use an ID once. But of course if I use classes instead, All the comment sections slide down because now they're all the same class. See below for my HTML and JavaScript. So if someone has a better method out there, please help :) $(function () { $(".comment-box").slideUp(); //when "comment" is clicked, slide down the comment box. if ($(".comment-box-btn").click(function () { $(".comment-box").slideDown(); })); //when "cancel" is clicked, slide up the comment box. if ($(".close-comment-box").click(function () { $(".comment-box").slideUp() })); }); And here's the HTML used //anchor for "Comment" <a class="comment-box-btn" href="#"><i class="icon-comment"></i> Comment</a> //comment box <div class="row comment-box" style="display:none;"> <div class="col-md-12"> <form accept-charset="UTF-8" action="" method="post"> <textarea class="form-control animated" cols="180" id="new-comment" name="comment" placeholder="Comment.." rows="1"></textarea> <div class="text-right" style="margin-top:20px;"> <a class="btn btn-default close-comment-box" href="#"> <span class="glyphicon glyphicon-remove"></span> Cancel</a> <button class="btn btn-info" type="submit">Comment</button> </div> </form> </div> </div>

  • Why won't this piece of my code write to file

    - by user2934783
    I am developing a c++ banking system. I am able to get the float, newbal, values correctly and when I try to write to file, there is no data in the file. else { file>>firstname>>lastname; cout<<endl<<firstname<<" "<<lastname<<endl; cout<<"-----------------------------------\n"; string line; while (getline(file, line)) { //stringstream the getline for line string in file istringstream iss(line); if (iss >> date >> amount) { cout<<date<<"\t\t$"<<showpoint<<fixed<<setprecision(2)<<amount<<endl; famount+=amount; } } cout<<"Your balance is $"<<famount<<endl; cout<<"How much would you like to deposit today: $"; cin>>amountinput; float newbal=0; newbal=(famount+=amountinput); cout<<"\nYour new balance is: $"<<newbal<<".\n"; file<<date<<"\t\t"<<newbal; //***This should be writing to file but it doesn't. file.close(); The text file looks like this: Tony Gaddis 05/24/12 100 05/30/12 300 07/01/12 -300 //Console Output looks like this Tony Gaddis 05/24/12 100 05/30/12 300 07/01/12 -300 Your balance is: #1 How much wuld you like to deposit: #2 Your new balance is: #1 + #2 write to file close file. //exits to main loop:::: How can I make it write to file and save it, and why is this happening. I tried doing it with ostringstream as well considering how I used istringstream for the input. But it didn't work either :\ float newbal=0; newbal=(famount+=amountinput); ostringstream oss(newbal); oss<<date<<"\t\t"<<newbal; I am trying to self teach c++ so any relevant information would be kindly appreciated.

  • Which Cassandra API provides the highest level of abstraction?

    - by knorv
    There are a lot of Cassandra API:s available and usually the programming language preference determines the choice of API. However, if we take the programming language component out of the equation, what Cassandra API provides the highest level of abstraction? Definition of "level of abstraction" in this context: An API providing a lot of extra goodies such as index handling, etc would be considered being at a higher abstraction layer than a bare bones "close to Thrift" API.

  • Reading binary data from stdin

    - by thebeav
    Is it possible to read stdin as binary data in Python 2.6? If so, how? I see in the Python 3.1 documentation that this is fairly simple, but the facilities for doing this in 2.6 don't seem to be there. If the methods described in 3.1 aren't available, is there a way to close stdin and reopen in in binary mode?

  • regex in python, can this be improved upon?

    - by tipu
    I have this piece of code that finds words that begin with @ or #, p = re.findall(r'@\w+|#\w+', str) Now what irks me about this is repeating \w+. I am sure there is a way to do something like p = re.findall(r'(@|#)\w+', str) That will produce the same result but it doesn't, it instead returns only # and @. How can that regex be changed so that I am not repeating the \w+? This code comes close, p = re.findall(r'((@|#)\w+)', str) But it returns [('@many', '@'), ('@this', '@'), ('#tweet', '#')] (notice the extra '@', '@', and '#'.

  • Scalability of Boost.Asio

    - by samm
    I'm curious how far others have pushed Boost.Asio in terms of scalability. I am writing an application that may use close to 1000 socket objects, a handful of acceptor objects, and many thousand timer objects. I've configured it such that there's a thread pool invoking io_service::run and use strands in the appropriate places to ensure my handlers do not stomp on each other. My platform is Red Hat Enterprise Linux with Boost 1.39, though I'm not opposed to upgrading to a more recent version of boost.

  • A question about making a C# class persistant during a file load

    - by Adam
    Apologies for the indescriptive title, however it's the best I could think of for the moment. Basically, I've written a singleton class that loads files into a database. These files are typically large, and take hours to process. What I am looking for is to make a method where I can have this class running, and be able to call methods from within it, even if it's calling class is shut down. The singleton class is simple. It starts a thread that loads the file into the database, while having methods to report on the current status. In a nutshell it's al little like this: public sealed class BulkFileLoader { static BulkFileLoader instance = null; int currentCount = 0; BulkFileLoader() public static BulkFileLoader Instance { // Instanciate the instance class if necessary, and return it } public void Go() { // kick of 'ProcessFile' thread } public void GetCurrentCount() { return currentCount; } private void ProcessFile() { while (more rows in the import file) { // insert the row into the database currentCount++; } } } The idea is that you can get an instance of BulkFileLoader to execute, which will process a file to load, while at any time you can get realtime updates on the number of rows its done so far using the GetCurrentCount() method. This works fine, except the calling class needs to stay open the whole time for the processing to continue. As soon as I stop the calling class, the BulkFileLoader instance is removed, and it stops processing the file. What I am after is a solution where it will continue to run independently, regardless of what happens to the calling class. I then tried another approach. I created a simple console application that kicks off the BulkFileLoader, and then wrapped it around as a process. This fixes one problem, since now when I kick off the process, the file will continue to load even if I close the class that called the process. However, now the problem I have is that cannot get updates on the current count, since if I try and get the instance of BulkFileLoader (which, as mentioned before is a singleton), it creates a new instance, rather than returning the instance that is currently in the executing process. It would appear that singletons don't extend into the scope of other processes running on the machine. In the end, I want to be able to kick off the BulkFileLoader, and at any time be able to find out how many rows it's processed. However, that is even if I close the application I used to start it. Can anyone see a solution to my problem?
