  • Inserting a WAV at a certain point in an audio file using python

    - by Onion
    My problem is the following: I have a 2-minute long WAV file, and my aim is to insert another WAV file (7 seconds long), at a certain point in the first WAV file (say, 0:48), essentially combining the two WAVs, using python. Unfortunately I haven't been able to figure out how to do that, and was wondering if there was some obvious solution that I was missing, or if it is even feasible to do with python. Is there perhaps a library available that might provide a solution? Thanks to all in advance.

  • iOS get file size on disk

    - by F2_CMD
    I'm trying to get the size on disk of a file in iOS using Objective C. As of now I've been able to get the actual size of the file and other file information using NSFileManager and then getting the attributes attributesOfItemAtPath:error but not the size on disk. I also tried getting the file size from struct stat but again it doesn't give me size on disk.I tried using NSTask to make a call to du -h but iOS didn't allow me to fork other processes. Any ideas are welcome :) I know this questions is similar to many others but the difference is that I'm trying to do this in iOS and most of the methods used in other systems don't work here. Thanks

  • Error with global variable in php not extending to included php file

    - by phileaton
    I have an html file that calls has a php section in the header like so: $page = basename($_SERVER['PHP_SELF']); Now further down in the html file I have a included footer like so: <?php include("footer.php"); ?> In this script I am referencing the $page variable, but it doesn't find it. I tried echoing the variable and nothing happened. When I place the basename() code in the footer.php file though, it handled it fine. I'd like to be efficient with the coding, so how can I get the footer.php file to get that $page variable? Is there a better way to do this than including the $page variable twice?

  • how to install a file handle in perl class

    - by Haiyuan Zhang
    please looku up the following code first. #! /usr/bin/perl package foo; sub new { my $pkg = shift; my $self = {}; my $self->{_fd} = undef; bless $self, $pkg; return $self; } sub Setfd { my $self = shift; my $fd = shift; $self_->{_fd} = $fd; } sub write { my $self = shift; print $self->{_fd} "hello word"; } my $foo = new foo; My intention is to store a file handle within a class using hash. the file handle is undefined at first, but can be initilized afterwards by calling Setfd function. then write can be called to actually write string "hello word" to a file indicated by the file handle, supposed that the file handle is the result of a success "write" open. but, perl compiler just complains that there are syntax error in the "print" line. can anyone of you tells me what's wrong here? thanks in advance.

  • Write to text file using ArrayList

    - by Ugochukwutubelum Chiemenam
    The program is basically about reading from a text file, storing the current data into an ArrayList, then writing data (from user input) into the same text file. Kindly let me know where I am going wrong in this sub-part? The data inside the text file is as follows: abc t1 1900 xyz t2 1700 The compiler is showing an error at the line output.format("%s%s%s%n", public class justTesting { private Scanner input; private Formatter output; private ArrayList<Student> tk = new ArrayList<Student>(); public static void main(String[] args) { justTesting app = new justTesting(); app.create(); app.writeToFile(); } public void create() { Text entry = new Text(); Scanner input = new Scanner(System.in); System.out.printf("%s\n", "Please enter your name, ID, and year: "); while (input.hasNext()) { try { entry.setName(input.next()); entry.setTelNumber(input.next()); entry.setDOB(input.next()); for (int i = 0; i < tk.size(); i++) { output.format("%s%s%s%n", tk.get(i).getName(), tk.get(i) .getTelNumber(), tk.get(i).getDOB()); } } catch (FormatterClosedException fce) { System.err.println("Error writing to file."); return; } catch (NoSuchElementException nsee) { System.err.println("Invalid input. Try again: "); input.nextLine(); } System.out.printf("%s\n", "Please enter your name, ID, and year: "); } } public void writeToFile() { try { output = new Formatter("testing.txt"); } catch (SecurityException se) { System.err .println("You do not have write access permission to this file."); System.exit(1); } catch (FileNotFoundException fnfe) { System.err.println("Error opening or creating file."); System.exit(1); } } }

  • Application freezes when performing help file search

    - by ralphos
    I have a large C# application and a help file in *.chm format. When I press F1 to display this help file and select "Search" tab, type something and click "List Topics" button, both the help window and the entire application freeze. What's interesting when I simply open the *.chm file in the Windows Explorer, the search functionality works brilliantly. In order to display the help file from my application, I am executing: Help.ShowHelp(this, helpFileName); This method is executed from within the main form of the application on the UI thread.

  • append text to lines in a CSV file

    - by MichaelMcCabe
    This question seems to have been asked a million times around the web, but I cannot find an answer which will work for me. Basically, I have a CSV file which has a number of columns (say two). The program goes through each row in the CSV file, taking the first column value, then asks the user for the value to be placed in the second column. This is done on a handheld running Windows 6. I am developing using C#. It seems a simple thing to do. But I cant seem to add text to a line. I cant use OleDb, as System.Data.Oledb isnt in the .Net version I am using. I could use another CSV file, and when they complete each line, it writes it to another CSV file. But the problems with that are - The file thats produced at the end needs to contain EVERY line (so what if they pull the batterys out half way). And what if they go back, to continue doing this another time, how will the program know where to start back from.

    - by John
    I'm currently using the magento admin interface, trying to upload an image in the "manage products" and I get the error "file was not uploaded" after I browse the file and click "upload file". I've looked on other forums and the main solution I saw were to make sure that php.ini has the following lines... magic_quotes_gpc = off short_open_tag = on extension=pdo.so extension=pdo_mysql.so I have Windows/IIS with ISAPI_Rewrite. Is there a max file upload size that I can change somewhere. I'm uploading pictures from my local desktop of size ~100kb. help!
