  • Why does my javascript file sometimes compressed while sometimes not?(IIS Gzip problem)

    - by Kevin Yang
    i enable gzip for javascript file in my iis settings, here 's the corresponding config section. <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files"> <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" staticCompressionLevel="10" dynamicCompressionLevel="8" /> <dynamicTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/soap+msbin1" enabled="true" /> <add mimeType="*/*" enabled="false" /> </dynamicTypes> <staticTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/javascript" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="*/*" enabled="false" /> </staticTypes> </httpCompression> currently, when i download my js file, it seems that sometimes server return the gzip one, and sometimes not. i dont know why, and how to debug that. If a file is already gzipped, it should be cached in local disk, and next time someone visit that file again, iis kernel should return the cache gzip file directly without compressing it again. Is that right?

  • Using XSD file in VS2005

    - by xt_20
    Hello all I want to write an XML file. I have created an XSD file named XMLSchema.xsd, and run the command 'xsd /c XMLSchema.xsd' which generated a c# class file. Now, how do I use this file to generate XML files? Part of my code: <?xml version="1.0" encoding="utf-8"?> <xs:schema id="XMLSchema" targetNamespace="http://tempuri.org/XMLSchema.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/XMLSchema.xsd" > <xs:element name="root"> <xs:complexType> <xs:sequence> <xs:element name="Audit"> <xs:complexType> ... which generates a c# class 'root'. How do I call 'root' from my C# web program? Thanks

  • LNK 1104 error to lib file - Continues despite removing includes and links

    - by user1556594
    A link error to a lib file popped up out of the blue in a c++ application of mine after code was working fine in my last session. Error 1 error LNK1104: cannot open file '..........\Program Files (x86)\FMOD SoundSystem\FMOD Programmers API Windows\api\lib\fmodex_vc.lib' I triple checked my project directories were set up correctly to link to the lib file, that the file existed in said directory and that it was a working version of the .lib. My next step was to remove the includes to the file and the links to bypass the error and work on the rest of my code until the problem was solved. The error remains, however, despite: Commenting out absolutely every include relating to the lib. Commenting out absolutely every line of code dependant on the includes. Removing the directory from VC++ Directories in the project properties. Checking the Additional Library Directories field was also clear of references. To my understanding this should have made the library and related code virtually non-existant to the compiler. What am I missing? The library itself is fmodex_vc.lib - part of the FMOD API for providing sound to interactive applications. Again, the application was working one session, but failed to compile the next. I hadn't touched the code since so this led me to believe some aspect of VS is at fault. I'd like to avoid the time involded in re-installing if possible as I'm on the clock for a review tomorrow evening and there are a few more things I'd like to smooth out before then. If necessary, however, I won't hesitate. Very much appreciate the help.

  • loading javascript file after jquery.ready

    - by Spines
    I want to load a javascript file at the end of jquery.ready so that the code in my ready handler doesn't have to wait to execute until this large javascript file is loaded. My jquery.ready code doesn't rely on this javascript file at all. Would this be a good way to do that? $(function(){ ... ... $('head').append('<script type="text/javascript" src="/largejs.js"></script>'); });

  • Paperclip - Validate File Type but not Presence

    - by Lowgain
    I am using paperclip to handle my file uploads, and in one situation I don't want the file to be mandatory. I do however want to make sure it is a specific file type when it is present. I have this: class TestModel < ActiveRecord::Base #stuff has_attached_file :sound #etc... validates_attachment_content_type :sound, :content_type => ['audio/mp3', 'application/x-mp3'] end And when I have no sound file present, it tells me it is not one of the valid content types. I've tried adding '' to the :content_type array, which also doesn't work! I also attempted creating a lambda procedure for the :if property, but I can't get it to run without some kind of error. Anything missing here?

  • Android library to get pitch from WAV file

    - by Sakura
    I have a list of sampled data from the WAV file. I would like to pass in these values into a library and get the frequency of the music played in the WAV file. For now, I will have 1 frequency in the WAV file and I would like to find a library that is compatible with Android. I understand that I need to use FFT to get the frequency domain. Is there any good libraries for that? I found that [KissFFT][1] is quite popular but I am not very sure how compatible it is on Android. Is there an easier and good library that can perform the task I want? EDIT: I tried to use JTransforms to get the FFT of the WAV file but always failed at getting the correct frequency of the file. Currently, the WAV file contains sine curve of 440Hz, music note A4. However, I got the result as 441. Then I tried to get the frequency of G4, I got the result as 882Hz which is incorrect. The frequency of G4 is supposed to be 783Hz. Could it be due to not enough samples? If yes, how much samples should I take? //DFT DoubleFFT_1D fft = new DoubleFFT_1D(numOfFrames); double max_fftval = -1; int max_i = -1; double[] fftData = new double[numOfFrames * 2]; for (int i = 0; i < numOfFrames; i++) { // copying audio data to the fft data buffer, imaginary part is 0 fftData[2 * i] = buffer[i]; fftData[2 * i + 1] = 0; } fft.complexForward(fftData); for (int i = 0; i < fftData.length; i += 2) { // complex numbers -> vectors, so we compute the length of the vector, which is sqrt(realpart^2+imaginarypart^2) double vlen = Math.sqrt((fftData[i] * fftData[i]) + (fftData[i + 1] * fftData[i + 1])); //fd.append(Double.toString(vlen)); // fd.append(","); if (max_fftval < vlen) { // if this length is bigger than our stored biggest length max_fftval = vlen; max_i = i; } } //double dominantFreq = ((double)max_i / fftData.length) * sampleRate; double dominantFreq = (max_i/2.0) * sampleRate / numOfFrames; fd.append(Double.toString(dominantFreq)); Can someone help me out? EDIT2: I manage to fix the problem mentioned above by increasing the number of samples to 100000, however, sometimes I am getting the overtones as the frequency. Any idea how to fix it? Should I use Harmonic Product Frequency or Autocorrelation algorithms?

  • Ruby - Read file in batches

    - by Algorist
    Hi, I am reading a file that is 10mb in size and which contains some id's. I read them into a list in ruby. I am concerned that it might cause memory issues in the future, when the number of id's in file might increase. Is there a effective way of reading a large file in batches? Thank you

  • Determine cluster size of file system in Python

    - by Philip Fourie
    I would like to calculate the "size on disk" of a file in Python. Therefore I would like to determine the cluster size of the file system where the file is stored. How do I determine the cluster size in Python? Or another built-in method that calculates the "size on disk" will also work. I looked at os.path.getsize but it returns the file size in bytes, not taking the FS's block size into consideration. I am hoping that this can be done in an OS independent way...

    - by JasonHorner
    I have a file that is tab delimited. I would like a powershell script that counts the number of tabs in each line. I came up with this: ${C:\tabfile.txt} |% {$_} | Select-String \t | Measure-Object | fl count it yields 3, Which is the number of lines in the file. any pointers to what I'm doing wrong? I would like it to print a single number for each line in the file.

  • StreamWriter not creating new file

    - by fearofawhackplanet
    I'm trying to create a new log file every hour with the following code running on a server. The first log file of the day is being created and written to fine, but no further log files that day get created. Any ideas what might be going wrong? No exceptions are thrown either. private void LogMessage(Message msg) { using (StreamWriter sw = File.AppendText(_logDirectory + DateTime.Today.ToString("yyyyMMddHH") + ".txt")) { sw.WriteLine(msg.ToString()); } }

  • Download dynaic file with GWT

    - by Maksim
    I have a GWT page where user enter data (start date, end date, etc.), then this data goes to the server via RPC call. On the server I want to generate Excel report with POI and let user save that file on their local machine. This is my test code to stream file back to the client but for some reason it does not know: public class ReportsServiceImpl extends RemoteServiceServlet implements ReportsService { public String myMethod(String s) { File f = new File("/excelTestFile.xls"); String filename = f.getName(); int length = 0; try { HttpServletResponse resp = getThreadLocalResponse(); ServletOutputStream op = resp.getOutputStream(); ServletContext context = getServletConfig().getServletContext(); resp.setContentType("application/octet-stream"); resp.setContentLength((int) f.length()); resp.setHeader("Content-Disposition", "attachment; filename*=\"utf-8''" + filename + ""); byte[] bbuf = new byte[1024]; DataInputStream in = new DataInputStream(new FileInputStream(f)); while ((in != null) && ((length = in.read(bbuf)) != -1)) { op.write(bbuf, 0, length); } in.close(); op.flush(); op.close(); } catch (Exception ex) { ex.printStackTrace(); } return "Server says: " + filename; } } I've red somewhere on internet that you can't do file stream with RPC and I have to use Servlet for that. Is there any example of how to use Servlet and how to call that servlet from ReportsServiceImpl
