  • How to create thumbnail images from DOC/RTF/PDF/XLS files

    - by imdadhusen
    I need to ask if any of you has any knowledge of creating file thumbnails on the fly. I have found a free component but it works only for PDF files, PDFThumbnailer. But my requirement is to convert DOC/RTF/PDF/XLS files to thumbnails on the fly, and if possible allow to save it as an image for later reference which currently PDFThumbnailer doesnt allow. PDFThumbnailer takes the pdf file and renders an image for it on browser, if that image can also be saved somehow to my machine that would be great too. Please guide me of how to achieve the above requirements. Any help for any filetype is appreciated. Thanks Imdadhusen

  • C#, working with files, "Unauthorized Access"?

    - by Rob
    Hi, I'm learning about opening and saving files with C# and it seems that vista won't let my program save to a file on the root of C:\ , unless I run it in administrator mode. Any ideas how to allow my program to play around with whatever files it wants? Thanks! string name; private void button2_Click(object sender, EventArgs e) ///// OPEN ///// { if (openFileDialog1.ShowDialog() == DialogResult.OK) { name = openFileDialog1.FileName; textBox1.Clear(); textBox1.Text = File.ReadAllText(name); textBox2.Text = name; } } private void button1_Click(object sender, EventArgs e) ///// SAVE ///// { File.WriteAllText(name, textBox1.Text); }

  • ftp connects but files aren't visible browsing

    - by YsoL8
    Hello If this should be on that other site, please don't shoot me, as I can't remember the name or the url. I have an ftp account in Dreamweaver that connects to the remote site and appears to be uploading files as normal. But when I browse to the location I can't see any new files or changes to the index page. (I've uploaded index.php and connect.php). I'm getting a 404 page. I suspect the host directory is wrong, but looking at the file tree, I can't see the folder I'm supposed to be using, so I'm uploading to the apparent site root. Any guidance on this?

  • Improve disk read performance (multiple files) with threading

    - by pablo
    I need to find a method to read a big number of small files (about 300k files) as fast as possible. Reading them sequentially using FileStream and reading the entire file in a single call takes between 170 and 208 seconds (you know, you re-run, disk cache plays its role and time varies). Then I tried using PInvoke with CreateFile/ReadFile and using FILE_FLAG_SEQUENTIAL_SCAN, but I didn't appreciate any changes. I tried with several threads (divide the big set in chunks and have every thread reading its part) and this way I was able to improve speed just a little bit (not even a 5% with every new thread up to 4). Any ideas on how to find the most effective way to do this?

  • How to get latest files in C#

    - by Newbie
    I have some files with same name but with different dates. Basically we are finding the files with most recent dates The file patterns are <FileNames><YYYYMMDD><FileExtension> e.g. test_20100506.xls indicates <FileNames> = test_ <YYYYMMDD> = 20100506 <FileExtension> = .xls Now in the source folder, the files are standardization_20100503.xls, standardization_20100504.xls, standardization_20100305.xls, replacement_20100505.xls As can be seen that, standardization_.xls are 3 in numbers but replacement_.xls is only 1. The output will be a list of file names whose content will be standardization_20100504.xls and replacement_20100505.xls Because among all the standardization_.xls is the most recent one and replacement_.xls is also the same. I have tried with my own logic but somehow failed. My idea is as under private static void GetLatestFiles(ref List<FileInfo> validFiles) { List<FileInfo> validFilesTemp = new List<FileInfo>(); for (int i = 0; i < validFiles.Count; i++) { for (int j = i+1; j < validFiles.Count; j++) { string getFileTextX = ExtractText(validFiles[i].Name); string getFileTextY = ExtractText(validFiles[j].Name); if (getFileTextX == getFileTextY) { int getFileDatesX = Convert.ToInt32(ExtractNumbers(validFiles[i].Name)); int getFileDatesY = Convert.ToInt32(ExtractNumbers(validFiles[j].Name)); if (getFileDatesX > getFileDatesY) { validFilesTemp.Add(validFiles[i]); } else { validFilesTemp.Add(validFiles[j]); } } } } validFiles.Clear(); validFiles = validFilesTemp; } The ExtractNumbers is: public static string ExtractNumbers(string expr) { return string.Join(null, System.Text.RegularExpressions.Regex.Split(expr, "[^\\d]")); } and the ExtractText is public static string ExtractText(string expr) { return string.Join(null, System.Text.RegularExpressions.Regex.Split(expr, "[\\d]")); } I am using c#3.0 and framework 3.5 Help needed .. it's very urgent Thanks .

  • Accessing and encoding of properties files

    - by NoozNooz42
    I'm used to work with properties files, for example from Ant. Where I can simply reference the property file doing something like that: <property file="webapp_DO_NOT_COMMIT.properties"/> (the file is so named because our DVCS is configured as to never commit files containing "DO_NOT_COMMIT" to prevent committing credentials/passwords/etc.) Here's a very simple .properties file example: passwd=brokencleartextpassword Now I want to put some configuration in another, similar, properties file that I need to access from my Java code. How should I go about it? I also have another related question: is the character encoding of .properties file defined by any spec?

  • GitHub: searching through older versions of files

    - by normski
    I know that using GitHub I can search through all the current versions of my files in a repo. However, I would also like to search through the older versions of my repo files. For example, say, I used to have a function called get_info() in my code, but deleted it several versions ago, is it possible to search for get_info and find the code. If it is not possible using GitHub, is it possible from the git command line? EDIT Thanks to @Mark Longair for showing how this can be done from the git command line. If it's not possible in GitHub it would be a great feature to have.

  • Visual source safe headaches - Deleting files

    - by maxp
    I will pre-empt and say we are stuck using VSS here so changing it is not an option. Anyway, one person, 'user a' is deleting a file from their project. They then do a 'get latest' on the folder and it doesn't come back, so the user assumes they have truely deleted it from the project. We have another user, 'user b', who then looks at 'pending checkins', sourcesafe will then do a scan of all the files in 'user b's project. It then wants to 're-add' all of the files user a deleted. This has caused a huge headache for the team. Any suggestions to stop this from happening again?

  • SVN files edited thru FTP, How do I fix the edited files so they work thru SVN again?

    - by Bobby
    Basically, a 3rd party analyst we brought on to make some improvements to our site decided to edit files directly on the live server threw FTP. Any time we make changes to those pages threw SVN we have PHP parse errors. Things should be edited threw the SVN and committed. We have our working copies setup so we can edit them how ever we want while having them running under apache for testing. We commit all of our changes to a local repository, then commit from there to the live server. The code on the live server that causes the parse error has " .mine" and " .rxxxx", and my question is, how can I revert those files back to before they were edited thru FTP so I can update them threw SVN again?

  • Bash redirection: save stderr/stdout to different files and still print them out on a console

    - by Alby
    Here is a simple program. class Redirection { public static void main (String args[]){ System.out.println("Hello World_Stdout"); System.err.println("Hello World_Stderr"); } } I want to see the all the outputs on a console, but at the same time I want to store stdout and stderr in different files. I tried the following command, to no avail. $java Redirection 3>&1 2>stderr 1>stdout 1>&3 2>&3 stderr& stdout files have the file size of 0. So basically I want to do what "tee" command does but I also want to capture stderr as well.

  • Ruby: Parse Excel 95-2003 files?

    - by Larry K
    Is there a way to read Excel 97-2003 files from Ruby? Background I'm currently using the Ruby Gem parseexcel -- http://raa.ruby-lang.org/project/parseexcel/ But it is an old port of the perl module. It works fine, but the latest format it parses is Excel 95. And guess what? Excel 2007 will not produce the Excel 95 format. John McNamara has taken over duties as the maintainer for the Perl Excel parser, see http://search.cpan.org/~jmcnamara/Spreadsheet-ParseExcel-0.55/lib/Spreadsheet/ParseExcel.pm The current version will parse Excel 95-2003 files. But is there a port to Ruby? My other thought is to build some Ruby to Perl glue code to enable use of the Perl library itself from Ruby. Eg, see http://stackoverflow.com/questions/451636/whats-the-best-way-to-export-utf8-data-into-excel/620612#620612 (I think it would be much faster to write the glue code than to port the parser.) Thanks, Larry

  • Secure method for linking to image files uploaded via custom CMS

    - by letseatfood
    How does one provide a direct URL for an image file (JPEG) that is secure? For example, if a PHP script writes uploaded images to directory http://www.somehost.com/images, is it okay to provide http://www.somehost.com/images/someimage.jpg as the URL, or is there a more secure way to do this? Should I look into something like the permalink feature that is a part of Wordpress? I am not sure if that is related. The main reason I ask is that I have a custom PHP/MySQL CMS for managing images. I would like for the client to be able to copy a link to the image they want and then include it in a TinyMCE text editor for inserting the image in their website. Thanks!

  • Store multiple XML files in Android

    I am developing a survey android app so that: Each survey is downloaded from server as XML file. A survey can have multiple versions (new survey, new XML). When a new XML is downloaded it should overwrite its corresponding previous XML. I would like to store the files in a sqlite database. How can I insert my files into the db? Should I use BLOB or store the content of the XML as string? In any case how should I do it?

  • Organizing c# code into different files

    - by Adam S
    Hi everyone. I've gotten to a point where my main code file is about a thousand lines long and it's getting un-manageable; that is, I'm starting to get confused and not know where to locate some things. It's well-commented but there's just too much stuff. I'd really like to be able to organize my code into different files, each with its own purpose. I want to get all the help VS gives me as I type when I edit these other files. A picture can say a thousand words: Is what I'm trying to do even possible?

  • Apache not handling files correctly (Handler Help)

    - by ethanschaefer
    I'm trying to set up my .htaccess file correctly and I'm having an issue. The only thing my .htaccess file at the moment is: AddType application/x-httpd-php .php .html .htm This is included because my server is not parsing php in my html files. However when this is included in my .htaccess file, when I open a page in my browser, the user is prompted to save or open the file locally. I believe the answer to my issues is setting up an action to be done (run with php) however I cannot find out the path to my php files. Any help is appreciated.
