c# - Using "<input type="file" .... />" instead of asp:FileUpload -

-

i'm modifying existing asp.net project. original author erroneously tried create styled asp:fileupload setting visibility hidden , creating 2 custom styled browse , save buttons.

for security reason, ie not permit this. strategy instead try use input tags type="file", this example. if set input <input type="file" id="inputfile" /> how access/save file in code behind, inputfile.saveas("somefile.txt");? (in code behind) can inputfile.hasfile or there other analog of this?

as per recommendations i'm trying following:

             <td>                 enabled: <asp:checkbox id="checkbox2" runat="server" />    &nbsp;&nbsp;                 <div id="testfileuploader">>                    <input type="file" id="browserhidden" runat="server" />                    <div id="browservisible"><input type="text" id="filefield" /></div>                 </div>              </td>

so, can generate random file name future upload, based on guid @ codebehind of aspx page:

httppostedfile fileposted = request.files["uploadfieldnamefromhtml"];  if (fileposted != null && fileposted.contentlength > 0) {     string filenameapplication = system.io.path.getfilename(fileposted.filename);     string fileextensionapplication = system.io.path.getextension(filenameapplication);      // generating random guid new file @ server uploaded file     string newfile = guid.newguid().tostring() + fileextensionapplication;     // getting valid server path save     string filepath = system.io.path.combine(server.mappath("uploads"), newfile);      if (filenameapplication != string.empty)     {         fileposted.saveas(filepath);     } }

for request.files["uploadfieldnamefromhtml"] set id in html code here:

<input type='file' id='...' />

also, don't forget define runat="server" @ main form in aspx page, it's better set @ main form , don't forget enctype="multipart/form-data" parameter of <form>:

<body>     <form enctype="multipart/form-data" id="form1" runat="server">         <input type='file' id='uploadfieldnamefromhtml' /> ...

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
