  • ASP.NET MVC: Simple view to display contents of DataTable

    - by DigiMortal
    In one of my current projects I have to show reports based on SQL Server views. My code should be not aware of data it shows. It just asks data from view and displays it user. As WebGrid didn’t seem to work with DataTable (at least with no hocus-pocus) I wrote my own very simple view that shows contents of DataTable. I don’t focus right now on data querying questions as this part of my simple generic reporting stuff is still under construction. If the final result is something good enough to share with wider audience I will blog about it for sure. My view uses DataTable as model. It iterates through columns collection to get column names and then iterates through rows and writes out values of all columns. Nothing special, just simple generic view for DataTable. @model System.Data.DataTable @using System.Data; <h2>Report</h2> <table>     <thead>     <tr>     @foreach (DataColumn col in Model.Columns)         {                  <th>@col.ColumnName</th>     }         </tr>     </thead>             <tbody>     @foreach (DataRow row in Model.Rows)         {                 <tr>         @foreach (DataColumn col in Model.Columns)                 {                          <td>@row[col.ColumnName]</td>         }                 </tr>     }         </tbody> </table> In my controller action I have code like this. GetParams() is simple function that reads parameter values from form. This part of my simple reporting system is still under construction but as you can see it will be easy to use for UI developers. public ActionResult TasksByProjectReport() {      var data = _reportService.GetReportData("MEMOS",GetParams());      return View(data); } Before seeing next silver bullet in this example please calm down. It is just plain and simple stuff for simple needs. If you need advanced and powerful reporting system then better use existing components by some vendor.

  • Getting Junk characters while trying to print the file contents using Java

    - by user1523797
    I am reading a file's contents and trying to print the contents using java. But it prints junk characters along with the file content. Code: import java.io.*; public class ReadFile { public String readFile(String filePath){ StringBuilder contents = new StringBuilder(); File file = new File(filePath); try{ String lines = null; FileReader fileReader1 = new FileReader(file); BufferedReader buffer = new BufferedReader(fileReader1); while((lines = buffer.readLine())!=null){ contents.append(lines); } buffer.close(); } catch(FileNotFoundException ex){ System.out.println("File not found."); }catch(IOException ex){ System.out.println("Exception ocurred."); } return contents.toString(); } public static void main(String[] args){ ReadFile rf = new ReadFile(); String lines = rf.readFile("C:\\Data\\FaultDn.txt"); System.out.println("Original file contents: " + lines); } } The file contents are: partner.cisco.com:org-root/mac-pool-QA_MAC_Pool_5-Sep-2012_12:00 The output is: ![Alt Output](C:\Users\safarhee\Desktop\Output.jpg) Can you please point me to what I am missing in this code?

  • Moving only the contents of a map and not the map itself on linux

    - by WebDevHobo
    Using the cp command, one can move files and folders on linux. I want to make a new user and move the contents of the skeleton map to their home directory. I use this command: cp -r /etc/skel/ /home/testuser/ However, this only creates a skel folder in testuser. The idea is that the contents of the /etc/skel folder be copied to /home/testuser, and not that a map be made in /home/testuser with those contents. I've checked the man page: Link, but nothing on there really seemed like the solution to me. Is there a way to do this, or do files really need to be moved manually, 1 by 1?

  • Sharepoint .PDF contents displaying as 'searchtext.xml' in searches

    - by Green Muffins
    Hi Experts, I recently used installed ifilter in my sharepoint farm to enable searching of the contents of .pdf documents. All went well, except if I search for contents of any .pdf file, they appear in the search results with document title "searchtext.xml", and the link to the document gives a giant page of the .pdf contents in an .xml looking browser page. :s I have added .pdf filetypes to the search, so I am unsure why it is reading them incorrectly.. if I search for a .pdf document title such as 'document.pdf' it will display the result as a html page, though the link does follow to a readable .pdf file. Any help?

  • Mount Docker container contents in host file system

    - by dflemstr
    I want to be able to inspect the contents of a Docker container (read-only). An elegant way of doing this would be to mount the container's contents in a directory. I'm talking about mounting the contents of a container on the host, not about mounting a folder on the host inside a container. I can see that there are two storage drivers in Docker right now: aufs and btrfs. My own Docker install uses btrfs, and browsing to /var/lib/docker/btrfs/subvolumes shows me one directory per Docker container on the system. This is however an implementation detail of Docker and it feels wrong to mount --bind these directories somewhere else. Is there a proper way of doing this, or do I need to patch Docker to support these kinds of mounts?

  • Segfault when iterating over a map<string, string> and drawing its contents using SDL_TTF

    - by Michael Stahre
    I'm not entirely sure this question belongs on gamedev.stackexchange, but I'm technically working on a game and working with SDL, so it might not be entirely offtopic. I've written a class called DebugText. The point of the class is to have a nice way of printing values of variables to the game screen. The idea is to call SetDebugText() with the variables in question every time they change or, as is currently the case, every time the game's Update() is called. The issue is that when iterating over the map that contains my variables and their latest updated values, I get segfaults. See the comments in DrawDebugText() below, it specifies where the error happens. I've tried splitting the calls to it-first and it-second into separate lines and found that the problem doesn't always happen when calling it-first. It alters between it-first and it-second. I can't find a pattern. It doesn't fail on every call to DrawDebugText() either. It might fail on the third time DrawDebugText() is called, or it might fail on the fourth. Class header: #ifndef CLIENT_DEBUGTEXT_H #define CLIENT_DEBUGTEXT_H #include <Map> #include <Math.h> #include <sstream> #include <SDL.h> #include <SDL_ttf.h> #include "vector2.h" using std::string; using std::stringstream; using std::map; using std::pair; using game::Vector2; namespace game { class DebugText { private: TTF_Font* debug_text_font; map<string, string>* debug_text_list; public: void SetDebugText(string var, bool value); void SetDebugText(string var, float value); void SetDebugText(string var, int value); void SetDebugText(string var, Vector2 value); void SetDebugText(string var, string value); int DrawDebugText(SDL_Surface*, SDL_Rect*); void InitDebugText(); void Clear(); }; } #endif Class source file: #include "debugtext.h" namespace game { // Copypasta function for handling the toString conversion template <class T> inline string to_string (const T& t) { stringstream ss (stringstream::in | stringstream::out); ss << t; return ss.str(); } // Initializes SDL_TTF and sets its font void DebugText::InitDebugText() { if(TTF_WasInit()) TTF_Quit(); TTF_Init(); debug_text_font = TTF_OpenFont("LiberationSans-Regular.ttf", 16); TTF_SetFontStyle(debug_text_font, TTF_STYLE_NORMAL); } // Iterates over the current debug_text_list and draws every element on the screen. // After drawing with SDL you need to get a rect specifying the area on the screen that was changed and tell SDL that this part of the screen needs to be updated. this is done in the game's Draw() function // This function sets rects_to_update to the new list of rects provided by all of the surfaces and returns the number of rects in the list.

  • Chmod 777 to a folder and all contents on Apache web server

    - by Ryan Murphy
    I have just got new hosting for my website and I have a directory /www which I put all my website files within and a folder in that directory called 'store'. Within 'store' is several files and folders, I want to give the folder 'store' and all files and folders within the 'store' folder all permissions. How do I do this? I am guessing via .htaccess. I have tried inserting chmod 777 -R /store Into the .htaccess file but didn't work. Threw a big on screen error at me. I want to make all the files and folders within /store writable.

  • Aggregating Excel cell contents that match a label [migrated]

    - by Josh
    I'm sure this isn't a terribly difficult thing, but it's not the type of question that easily lends itself to internet searches. I've been assigned a project for work involving a complex spreadsheet. I've done the usual =SUM and other basic Excel formulas, and I've got enough coding background that I'm able to at least fudge my way through VBA, but I'm not certain how to proceed with one part of the task. Simple version: On Sheet 1 I have a list of people (one on each row, person's name in column A), on sheet 2 I have a list of groups (one on each row, group name in column A). Each name in Sheet 1 has its own row, and I have a "Data Validation" dropdown menu where you choose the group each person belongs to. That dropdown is sourced from Sheet 2, where each group has a row. So essentially the data validation source for Sheet 1's "Group" column is just "=Sheet2!$a1:a100" or whatever. The problem is this: I want each group row in Sheet 2 to have a formula which results in a list of all the users which have been assigned to that group on Sheet 1. What I mean is something the equivalent of "select * from PeopleTab where GROUP = ThisGroup". The resulting cell would just stick the names together like "Bob Smith, Joe Jones, Sally Sanderson" I've been Googling for hours but I can't think of a way to phrase my search query to get the results I want. Here's an example of desired result (Dash-delimited. Can't find a way to make it look nice, table tags don't seem to work here): (Sheet 1) Bob Smith - Group 1 (selected from dropdown) Joe Jones - Group 2 (selected from dropdown) Sally Sanderson - Group 1 (selected from dropdown) (Sheet 2) Group 1 - Bob Smith, Sally Sanderson (result of formula) Group 2 - Joe Jones (result of formula) What formula (or even what function) do I use on that second column of sheet 2 to make a flat list out of the members of that group?

  • Efficient way to check for changes to the contents of folders

    - by MrVimes
    I am creating an application that maintains a database of files of a certain type in a given folder (and all subfolders) Initially the program will recurse the folders and add any file it finds of that type to the database. I want the application to have the ability to re-scan the folder and add any files that were not there the last time the folders were scanned. It can't use the date created property of the file because there is a high chance of a file being added to the folders that isn't a new file. I am wondering what the most efficient way of doing this is, and if there is a way that doesn't involve checking each file is in the database already (which, if there are 5000 files would mean 5000 queries of a list 5000 items in size, or 25 million 'checks' for the sql engine to perform) I suppose a more specific question to acheive the same goal would be - is there a property of a file (in Microsoft Windows) that will reliably tell you when that file arrived in that folder.

  • Vista is showing contents of flash drive that was previously connected

    Today, after I clicked "folder X" in my external hard drive, instead of seeing the contents of "folder X", I see the contents of my flash drive (the last time it was connected)...which is not connected to my computer. My flash drive's files show for a couple of seconds before I am brought to "folder X" which was the folder I wanted to go to as mentioned in the beginning of this post. Any idea why this happened? I'm using Vista 32-bit business edition.

  • Problem with sending cookies with file_get_contents

    - by Ikke
    Hi, i'm trying to get the contents from another file with file_get_contents (don't ask why). I have two files: test1.php and test2.php. Test1.php returns a string, bases on the user that is logged in. Test2.php tries to get the contents of test1.php and is being executed by the browser, thus getting the cookies. To send the cookies with file_get_contents, i create a streaming context: $opts = array('http' => array('header'=> 'Cookie: ' . $_SERVER['HTTP_COOKIE']."\r\n"))`; I'm retreiving the contents with: $contents = file_get_contents("http://www.domain.com/test1.php", false, $opts); But now I get the error: Warning: file_get_contents(http://www.domain.com/test1.php) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found Does somebody knows what i'm doing wroing here? edit: forgot to mention: Without the streaming_context, the page just loads. But withouth the cookies I don't get the info I need.

  • How to "demote" all titles and headings in Word 2010?

    - by dangowans
    I built a large help document for an application I wrote. I used all the default styles in Word 2010, including "Title", "Heading 1", "Heading 2", etc. Sadly, when I generated the Table of Contents, Titles were not included. I'm also now using chmProcessor to automatically generate a website from the document, and it's not including Titles in its Table of Contents either. I'd like to make all Titles into Heading 1s, all Heading 1s into Heading 2s, and Heading 2s into Heading 3s, etc. Is this possible without a huge manual effort? (I'm sure there's a better word than "demote" for this.)

  • Transfer disk contents *without* cloning tools

    - by Chris Cummins
    Is it possible to "clone" a disk which contains programs by performing a copy of all the disk contents (preserving file attributes) from source to destination disk, and unplugging the source disk and changing the drive letter of the destination disk to match that of the source? Context I have a two disk Windows 8 system with a system drive and a data drive. Recently, the data drive developed a number of bad sectors leading to IO errors. I have been sent a replacement drive so I simply need to clone the contents of this data drive onto the replacement. The drive contents include documents & media, user folders (My Documents and related), and some programs (games etc). Problem The problem is that the bad sectors on the source disk causes most disk cloning tools to fail with read errors. Attempted approaches include: Disk clone from live boot environment with Acronis True Image. Fails due to read errors. Disk clone from live boot environment with Clonezilla. Fails due to read errors. Disk clone using Roadkil's Unstoppable Copier. Fails due to hardware timeouts in the HDD (application hangs indefinitely). A straightforward copy from source to destination disk using FreeFileSync (preserving file attributes and metadata). This succeeds. So at the moment I have a replacement disk which contains all of the data from the original disk. Now all I need to is somehow get Windows to replace all references to the old disk to the new one. Is this possible by simply swapping the assigned drive letters? Any help would be greatly appreciated, thanks!

  • WINDOWS 7: Make the contents of two folders appear in one

    - by big_smile
    In Windows 7, I have three folders: "Images", "assets" and "all". I want the contents of "Images " and "assets" to appear in "all" automatically without copying those files into that folder (e.g. I don't want to duplicate the files). I also only want the contents to be copied over and not the folders themslves (The reason for this is that if the folders are copied over, they will become sub-directories. I am using a printing hot folder that access "all" but it can't see any subdirectories in "all"). When Images and Assets are updated (e.g. with files being added or deleted), "all" should automatically update as well. How can I do this? This is what I have tried: Libraries: This is a feature built into Windows. It works exactly as I want. However, the print hot folder cannot recognise the library as a folder. Sym Link Extension: I can use this to make the "images" and "assets" folders appear as a sub directories of "all". However, I want the contents of "images"/"assets" to appear in the "all" folder (I don't want the directories to appear as sub directories, because as stated, the print hot folder cannot access sub directories).

  • Need to merge multiple pdf's into a single PDF with Table Of Contents sections

    - by Jason
    Will have 50-100 single PDF's that we'll be generating with a php script. PDF's are generally grouped into groups of 10-20. Each group needs to have it's own Table of Contents or Index, and then there also needs to be a Master Table of Contents or Index at the beginning. Or if that is too difficult we could get away with a single Table of Contents at the beginning. What's the best way to go about this? Will we need to create the Table of Contents and then export that to PDF and append it to the beginning and mash the rest of the files after that? Or is there a better solution? And what's the best tool for us to merge the pdf's? Will be running on a Linux server.

  • Reducing the opacity on a div without reducing the opacity of the contents

    - by user352744
    Want to reduce the opacity of page contents container background without reducing the opacity of the contents. <div id="container"> <div id="page contents"> page contents goes here, like amazing articles and all that. </div> </div> Needs to be able to expand with the content, thus can't have a fixed height. Absolute positioning it underneath the content will mean there will be no relationship between the two divs and it wont expand with the contents, so I think this is a dead end, feel free to say otherwise. Can't use Jquery as could be too laggy and not instant. Other options preferred please. May have to use 'png' background images but were hoping not to as it is a template and needs to be able to change colour based on colour schemes. Could generate images on demand but not ideal. Oh and to top it off cant use CSS3 as wont work in IE! of course! Any suggestions?
