  • How do I show an embedded excel file in a WebPage?

    - by Juan Manuel Formoso
    I want to allow an Excel report to be viewed embedded in a WebPage... is there a way? I don't want to use an ActiveX, or OWC (Office Web Components), I just want to open an existing file from the internet explorer application. I don't want users to download and then open it. Using an iframe wouldn't be a problem, but my preliminary tests weren't successful Any ideas? Is it at all possible?

  • Template trick to optimize out allocations

    - by anon
    I have: struct DoubleVec { std::vector<double> data; }; DoubleVec operator+(const DoubleVec& lhs, const DoubleVec& rhs) { DoubleVec ans(lhs.size()); for(int i = 0; i < lhs.size(); ++i) { ans[i] = lhs[i]] + rhs[i]; // assume lhs.size() == rhs.size() } return ans; } DoubleVec someFunc(DoubleVec a, DoubleVec b, DoubleVec c, DoubleVec d) { DoubleVec ans = a + b + c + d; } Now, in the above, the "a + b + c + d" will cause the creation of 3 temporary DoubleVec's -- is there a way to optimize this away with some type of template magic ... i.e. to optimize it down to something equivalent to: DoubleVec ans(a.size()); for(int i = 0; i < ans.size(); i++) ans[i] = a[i] + b[i] + c[i] + d[i]; You can assume all DoubleVec's have the same # of elements. The high level idea is to have do some type of templateied magic on "+", which "delays the computation" until the =, at which point it looks into itself, goes hmm ... I'm just adding thes numbers, and syntheizes a[i] + b[i] + c[i] + d[i] ... instead of all the temporaries. Thanks!

  • Emacs: Changing the location of auto-save files

    - by Dominic Rodger
    I've currently got: (setq backup-directory-alist `((".*" . ,temporary-file-directory))) (setq auto-save-file-name-transforms `((".*" ,temporary-file-directory t))) in my .emacs, but that doesn't seem to have changed where auto-save files get saved (it has changed where backup files get saved. M-x describe-variable shows that temporary-file-directory is set to /tmp/, but when I edit a file called testing.md and have unsaved changes, I get a file called .#testing.md in the same directory. How can I make that file go somewhere else (e.g. /tmp/)? I've had no luck with these suggestions, so any suggestions welcome! If it helps, I'm on GNU Emacs 23.3.1, running Ubuntu.

  • PHP upload to GoDaddy hosted site

    - by 105894384987190582154
    Hi, relatively new to both hosting and PHP, so apologies for (probably) missing the obvious, but… I built a page which would allow file uploads to my site, following the example laid out here: W3Schools PHP upload exercise Through the File Manage on my Godaddy hosting, I created a folder named ’upload’ so that the file would land there after being uploaded through the page I had built. Part of the returned page that appears after submitted the file reads: Temp file: d:temptmpphpE4C9.tmp Stored in: upload/testfile.txt which would indicate that the file has been sucesscully uploaded given the code in the example. However, I cannot see the file in the ’upload’ folder via my File Manage, or anywhere else on the hosting of my site (as far as I can see). I also cannot see the ’temp’ folder anywhere either… Any help or clarification would be greatly appreciated. Thanks Tim

  • improve my python program to fetch the desire rows by using if condition

    - by user2560507
    unique.txt file contains: 2 columns with columns separated by tab. total.txt file contains: 3 columns each column separated by tab.

  • System Error when running PyQt4's loadUi()

    - by user633804
    Hello, I'm pretty new to Qt, Python and their combinations. I'm currently writing a QGIS plugin in python (I used QtCreator 2.1 (Qt Designer 4.7) to generate a .ui-file and am now trying to use it for a Quantum GIS plugin that's written in Python 2.5 (and running in the Quantum GIS Python 2.5 console)). I am running into trouble when loading the ui-file dynamically when the program runs the loadUi() function. What throws me off is that the error occurs outside my script. Does that mean, I'm passing something wrong into it? Where does the error come in? Any hints on what could be wrong? code_dir = os.path.dirname(os.path.abspath(__file__)) self.ui = loadUi(os.path.join(code_dir, "Ui_myfile.ui"), self) This is the Error Code I am getting (minus the first paragraph): File "C:/Dokumente und Einstellungen/name.name/.qgis/python/plugins\myfile\myfile_gui.py", line 42, in __ init __ self.ui = loadUi(os.path.join(code_dir, "Ui_myfile.ui"), self) File "C:\PROGRA~1\QUANTU~1\apps\Python25\lib\site-packages\PyQt4\uic__init__.py", line 112, in loadUi return DynamicUILoader().loadUi(uifile, baseinstance) File "C:\PROGRA~1\QUANTU~1\apps\Python25\lib\site-packages\PyQt4\uic\Loader\loader.py", line 21, in loadUi return self.parse(filename) File "C:\PROGRA~1\QUANTU~1\apps\Python25\lib\site-packages\PyQt4\uic\uiparser.py", line 768, in parse actor(elem) File "C:\PROGRA~1\QUANTU~1\apps\Python25\lib\site-packages\PyQt4\uic\uiparser.py", line 616, in createUserInterface self.traverseWidgetTree(elem) File "C:\PROGRA~1\QUANTU~1\apps\Python25\lib\site-packages\PyQt4\uic\uiparser.py", line 594, in traverseWidgetTree handler(self, child) File "C:\PROGRA~1\QUANTU~1\apps\Python25\lib\site-packages\PyQt4\uic\uiparser.py", line 233, in createWidget topwidget.setCentralWidget(widget) SystemError: error return without exception set

  • iTunes + External Hard Drive problem

    - by Samwho
    Okay, so I've always stored my music on my external hard drive and run it from there with iTunes. Recently, however, it's being a little awkward. I think it was because I accidentally tried to run a song off my hard drive when it wasn't plugged in and, as would be expected, it said it couldn't find it. So I plug the hard drive in, locate the file and off it goes. But now it won't find any of the files... When I go to the "Get Info" page on the right click menu on a song I notice it has prepended file://localhost/ to everything, so my paths look like this: "file://localhost/E:/Sam/Media/Music/[song name]" I went into the iTunes Music Library.xml file and did a search and replace for file://localhost/ and replaced it with nothing and tried opening iTunes again and it just added file://localhost/ to every file again! Anyone have any idea why it does this and how to fix it without reimporting my library?

  • PHP's fopen is terminally failing

    - by Skittles
    Okay, I have GOT to be missing something totally rudimentary here. I have an extremely simple use of PHP's fopen function, but for some reason, it will not open the file no matter what I do. The odd part about this is that I use fopen in another function in the same script and it's working perfectly. I'm using the fclose in both functions. So, I know it's not a matter of a rogue file handle. I have confirmed the file's path and the existence of the target file also. I'm running the script at the command-line as root, so I know it's not apache that's the cause. And since I am running the script as root, I am fairly confident that permissions are not the issue. So, what on earth am I missing here? function get_file_list() { $file = '/home/site/tmp/return_files_list.txt'; $fp = fopen($file, 'r') or die("Could not open file: /home/site/tmp/return_files_list.txt for reading.\n"); $files_list = array(); while($line = fgets($fp)) { $files_list[] = $line; } fclose($fp); return $files_list; } function num_records_in_file($filename) { $fp = fopen( $filename, 'r' ); # or die("Could not open file: $filename\n"); $counter = 0; if ($fp) { while (!feof( $fp )) { $line = fgets( $fp ); $arr = explode( '|', $line ); if (( ( $arr[0] != 'HDR' && $arr[0] != 'TRL' ) && $arr[0] != '' )) { ++$counter; continue; } } } fclose( $fp ); return $counter; } As requested, here's both functions. The second function is passed an absolute path to the file. That is what I used to confirm that the file is there and that the path is correct.

  • C# comparing two files regex problem.

    - by Mike
    Hi everyone, what I'm trying to do is open a huge list of files (about 40k records, and match them on a line in a file that contains 2 millions records. And if my line from file A matches a line in file B write out that line. File A contains a bunch of files without extensions and file B contains full file paths including extensions. i'm using this but i cant get it to go... string alphaFilePath = (@"C:\Documents and Settings\g\Desktop\Arrp\Find\natst_ready.txt"); List<string> alphaFileContent = new List<string>(); using (FileStream fs = new FileStream(alphaFilePath, FileMode.Open)) using (StreamReader rdr = new StreamReader(fs)) { while (!rdr.EndOfStream) { alphaFileContent.Add(rdr.ReadLine()); } } string betaFilePath = @"C:\Documents and Settings\g\Desktop\Arryup\Find\eble.txt"; StringBuilder sb = new StringBuilder(); using (FileStream fs = new FileStream(betaFilePath, FileMode.Open)) using (StreamReader rdr = new StreamReader(fs)) { while (!rdr.EndOfStream) { string betaFileLine = rdr.ReadLine(); string matchup = Regex.Match(alphaFileContent, @"(\\)(\\)(\\)(\\)(\\)(\\)(\\)(\\)(.*)(\.)").Groups[9].Value; if (alphaFileContent.Equals(matchup)) { File.AppendAllText(@"C:\array_tech.txt", betaFileLine); } } } This doesnt work because the alphafilecontent is a single line only and i'm having a hard time figuring out how to get my regex to work on the file that contains all the file paths (Betafilepath) here is a sample of the beta file path. C:\arres_i\Grn\Ora\SEC\DBZ_EX1\Nes\001\DZO-EX00001.txt Here is the line i'm trying to compare from my alpha DZO-EX00001
