  • Creating Objects

    - by user1424667
    I have a general coding standard question. Is it bad practice to initialize and create an object in multiple methods depending on the outcome of a users choice. So for example if the user quits a poker game, create the poker hand with the cards the user has received, even if < 5, and if the user played till the end create object to show completed hand to show outcome of the game. The key is that the object will only be created once in actuality, there are just different paths and parameters is will receive depending on if the user folded, or played on to the showdown.

  • Passing class names or objects?

    - by nischayn22
    I have a switch statement switch ( $id ) { case 'abc': return 'Animal'; case 'xyz': return 'Human'; //many more } I am returning class names,and use them to call some of their static functions using call_user_func(). Instead I can also create a object of that class, return that and then call the static function from that object as $object::method($param) switch ( $id ) { case 'abc': return new Animal; case 'xyz': return new Human; //many more } Which way is efficient? To make this question broader : I have classes that have mostly all static methods right now, putting them into classes is kind of a grouping idea here (for example the DB table structure of Animal is given by class Animal and so for Human class). I need to access many functions from these classes so the switch needs to give me access to the class

  • Separating Db from business with Inherited classes using multiple views

    - by catalinux
    I have a software that has a car model that will be used in different views (listing, ads, detail page, carousel, up sell widget,etc). class CarModel extends DbModel{ } I look for a "nice way" (a combination of flexible, easy to maintain,etc) to have this used in views. I'm thinking at two different ways Having object views for each context CarViewBase{ var car;// of type CarModel function constructor(args){ //will instantienta internal variable car based on args } function getThumb(){ } function getTitle(){ } } CarListingView extends CarViewBase{ function getListing(){ } } CarAdsView extends CarViewBase{ //the busines rule changes for ads widget function getThumb(){ } } Extending directly the CarModel The challenges comes when My Car Model might need an abstract factory. Let's say I have a field on my car object that states the type of the car : a truck, or a bike, or van. How would affect that my object view? Let's say that getTitle() rule would be different for each type of it. How would you do it?

  • I overwrote a large file with a blank one on a linux server. Can I recover the existing file?

    - by user39234
    I came back to my machine, tried saving a file over ssh onto my linux server (CentOS). It failed. I wasn't interested in keeping any changes I had made so I closed my editor and reopened the file (over ssh). The save attempt wiped the file. I have made loads of changes to it since I last uploaded to revision control. Seeing as it has just wiped the file I assume the data is still there. It's just a text file (php), is there any way of recovering it?

  • I just deleted my backup file! How do I save it?

    - by Sammy
    I just accidentally deleted a backup file that I need to restore my system. It's an Acronis True Image TIB file. It was stored at H:\My backups and the name of the file was File_backup_2012-10-18.tib. I did a quick scan with Recuva 1.43.623 and it found the file using the recovery wizard, but it was unable to recover it. The "state" of the file is "unrecoverable". So the resulting file is 0 byte. I am trying to do a deep scan with Recuva right now but it takes a lot of time. If it should fail, what other recovery option do I have? Is there any other good file recovery software that's free to use for home users? I do have a second copy of the whole system partition, but I needed this file backup copy because it is more up to date. That's the file, right there! But why is Recuva unable to recover it?

  • unable to delete file (jpeg)

    - by ile
    I implemented helper for showing thumbnails from here Next to thumbnail, there is delete link which calls this controller // // HTTP POST: /Photo/Delete/1 [AcceptVerbs(HttpVerbs.Post)] public ActionResult Delete(int id, string confirmButton) { var path = "~/Uploads/Photos/"; Photo photo = photoRepository.GetPhoto(id); if (photo == null) return View("NotFound"); FileInfo TheFile = new FileInfo(Server.MapPath(path + photo.PhotoID + ".jpg")); if (TheFile.Exists) { photoRepository.Delete(photo); photoRepository.Save(); TheFile.Delete(); } else return View("NotFound"); return View(); } If I disable showing thumbnails then the file is deleted. Otherwise it sends error: System.IO.IOException: The process cannot access the file 'C:\Documents and Settings\ilija\My Documents\Visual Studio 2008\Projects\CMS\CMS\Uploads\Photos\26.jpg' because it is being used by another process. I also don't know if my file delete function is properly written. Searching on the net, I see everyone uses File.Delete(TheFile);, which i'm unable to use and I use TheFile.Delete(); For File.Delete(TheFile); i get following error: Error 1 'System.Web.Mvc.Controller.File(string, string, string)' is a 'method', which is not valid in the given context C:\Documents and Settings\ilija\My Documents\Visual Studio 2008\Projects\CMS\CMS\Controllers\PhotoController.cs 109 17 CMS Am I missing something here?

  • Looking for a web based, embeddable file manager

    - by Kristi H.
    I'm looking for a web based, embeddable file manager. I haven't found anything suitable through Google or the Stack Overflow archives. Does anyone know of a file manager that meets the following criteria? The file manager must… …be embeddable (e.g. Flash or a Java applet) …run from my server (no storing uploads in a remote location) …be licensed for business use (fees are okay) …let me disable uploads. Users shouldn't be able to upload files, only download them …allow me to tag files and/or place them in folders …let me disable authentication or handle it from the backend. My app already has a login system and I don't want to make users log in twice …allow users to select and download multiple files …have an attractive interface The file manager should… …have an external config file …display thumbnail previews for files …be skinnable …be actively developed or at least actively maintained Thanks for your help. I need a sophisticated file manager and I'd like to avoid writing it from scratch.

  • c++ File input/output

    - by Myx
    Hi: I am trying to read from a file using fgets and sscanf. In my file, I have characters on each line of the while which I wish to put into a vector. So far, I have the following: FILE *fp; fp = fopen(filename, "r"); if(!fp) { fprintf(stderr, "Unable to open file %s\n", filename); return 0; } // Read file int line_count = 0; char buffer[1024]; while(fgets(buffer, 1023, fp)) { // Increment line counter line_count++; char *bufferp = buffer; ... while(*bufferp != '\n') { char *tmp; if(sscanf(bufferp, "%c", tmp) != 1) { fprintf(stderr, "Syntax error reading axiom on " "line %d in file %s\n", line_count, filename); return 0; } axiom.push_back(tmp); printf("put %s in axiom vector\n", axiom[axiom.size()-1]); // increment buffer pointer bufferp++; } } my axiom vector is defined as vector<char *> axiom;. When I run my program, I get a seg fault. It happens when I do the sscanf. Any suggestions on what I'm doing wrong?

  • Passing a Batch File an Argument Containing a Quote Containing a Space

    - by Synetech inc.
    Hi, On many occasions I have dealt with passing batch files arguments with spaces, quotes, percents, and slashes and all sorts of combinations of them. Usually I managed to figure out how to accomplish what I want, but this time I am stuck. I have tried a couple of hundred combinations now and my head is starting to hurt. I’ve reduced the problem quite nicely. It’s a simple requirement: pass a double-quoted space from one batch file to another. That is, one batch file should pass some string X to another so that the the second one echos " ". I just can’t figure out what X should be. Here is a minimal batch file that demonstrates and attempt that does not work. (This BAT file takes the place of both by calling itself.) ::Goal is to print: ::" " ::That is, to pass a quoted space from a BAT file to a BAT file if not (%1)==() goto recurse %0 "" "" :recurse echo %1 pause It does not work. I’ve tried using "\" \"", """ """, """" """", "\"" "\"", ""\" \""", "^" ^"", ^"" "^", and so on. Either they print double double-quotes, lose everything after the space, or something else (that is wrong). Any ideas? Thanks.

  • Read whole ASCII file into C++ std::string

    - by Arrieta
    Hello, I need to read a whole file into memory and place it in a C++ std::string. If I were to read it into a char, the answer would be very simple: std::ifstream t; int lenght; t.open("file.txt", "r"); // open input file t.seekg(0, std::ios::end); // go to the end length = t.tellg(); // report location (this is the lenght) t.seekg(0, std::ios::beg); // go back to the beginning buffer = new char[length]; // allocate memory for a buffer of appropriate dimension t.read(buffer, length); // read the whole file into the buffer t.close(); // close file handle // ... do stuff with buffer here ... Now, I want to do the exact same thing, but using a std::string instead of a char. I want to avoid loops, i. e., I don't want to: std::ifstream t; t.open("file.txt", "r"); std::string buffer; std::string line; while(t){ std::getline(t, line); // ... append line to buffer and go on } t.close() any ideas?

  • Upload file using jquery dialog not working

    - by kandroid
    i want to upload file using jquery dialog. I have created a partial view and showing that partial view in the dialog. The problem is, when I directly browse the partial view and upload a file, it works perfect. BUT when I put the partial view inside a jquery dialog, it submits the form, but don't submits the file. So i have null value. I really dont understand what is the difference here!! Hope someone can help me to identify the problem. here is some codes; jquery codes: $('#UploadDialog').dialog({ autoOpen: false, width: 580, resizable: false, modal: true, open: function (event, ui) { $(this).load('@Url.Action("Upload","Notes")'); }, buttons: { "Upload": function () { $("#upload-message").html(''); $("#noteUploadForm").submit(); }, "Cancel": function () { $(this).dialog("close"); } } }); $(".uploadLink").click(function () { $('#UploadDialog').dialog('open'); }); return false; }); partial view: @using (Ajax.BeginForm("Upload", "Notes", null, new AjaxOptions { UpdateTargetId = "upload-message", InsertionMode = InsertionMode.Replace, HttpMethod = "POST", OnSuccess = "uploadSuccess" }, new { id = "noteUploadForm" , enctype="multipart/form-data"})) { <div> <div id="upload-message"></div> <div class="editLabel"> @Html.LabelFor(m => m.Notes.NoteTitle) </div> <div class="editText"> @Html.TextBoxFor(m => m.Notes.NoteTitle) </div> <div class="clear"></div> <div class="editLabel"> @Html.Label("Upload file") </div> <div class="editText"> <input type="file" name="file" />(100MB max size) </div> </div> }

  • Logic: Best way to sample & count bytes of a 100MB+ file

    - by Jami
    Let's say I have this 170mb file (roughly 180 million bytes). What I need to do is to create a table that lists: all 4096 byte combinations found [column 'bytes'], and the number of times each byte combination appeared in it [column 'occurrences'] Assume two things: I can save data very fast, but I can update my saved data very slow. How should I sample the file and save the needed information? Here're some suggestions that are (extremely) slow: Go through each 4096 byte combinations in the file, save each data, but search the table first for existing combinations and update it's values. this is unbelievably slow Go through each 4096 byte combinations in the file, save until 1 million rows of data in a temporary table. Go through that table and fix the entries (combine repeating byte combinations), then copy to the big table. Repeat going through another 1 million rows of data and repeat the process. this is faster by a bit, but still unbelievably slow This is kind of like taking the statistics of the file. NOTE: I know that sampling the file can generate tons of data (around 22Gb from experience), and I know that any solution posted would take a bit of time to finish. I need the most efficient saving process

  • basic file input using C

    - by user1781966
    So im working on learning how to do file I/O, but the book I'm using is terrible at teaching how to receive input from a file. Below is is their example of how to receive input from a file, but it doesn't work. I have copied it word for word, and it should loop through a list of names until it reaches the end of the file( or so they say in the book), but it doesn't. In fact if I leave the while loop in there, it doesn't print anything. #include <stdio.h> #include <conio.h> int main() { char name[10]; FILE*pRead; pRead=fopen("test.txt", "r"); if (pRead==NULL) { printf("file cannot be opened"); }else printf("contents of test.txt"); fscanf(pRead,"%s",name); while(!feof(pRead)) { printf("%s\n",name); fscanf(pRead, "%s", name); } getch(); } Even online, every beginners tutorial I see does some variation of this, but I can't seem to get it to work even a little bit.

    Im reading in 2 csv file: store_inventory & new_acquisitions... I want to be able to compare the store_inventory csv file with new_acquisitions. 1) If the item names match just update the quantity in store_inventory. 2) If new_acquisitions has a new item that does not exist in store_inventory, then add it to the store_inventory.

  • How to save file and read

    - by Jessy
    Hello everyone, I create a program that place random image in grid layout format. The size of the grid layout is 6 x 6 = 36. Only 10 were filled with images (each image was different) and the rest were empty. freeimagehosting.net/uploads/bfb7e85f63.jpg How can I save it to a file and read it again, so it will display the same images with same placement on the grid? Here is the code that I used to save the images: //image file String []arrPic = {"pic1.jpg","pic2.jpg","pic3.jpg","pic4.jpg","pic5.jpg","pic6.jpg","pic7.jpg","pic8.jpg","pic9.jpg","pic10.jpg",,"pic11.jpg","pic12.jpg","pic13.jpg"}; ArrayList<String> pictures = new ArrayList<String>(Arrays.asList(arrPic)); ArrayList<String> file = new ArrayList<String>(); JPanel pDraw = new JPanel(new GridLayout(6,6,2,2)); ... //fill all grids with empty label for (int i =0; i<(6*6); i++){ JLabel lbl = new JLabel(""); pDraw.add(lbl); } ... //Choose random box to be filled with images for(int i=0; i<10; i++){ Boolean number = true; while(number){ int n = rand.nextInt(35); if(!(arraylist.contains(n))) number = false; arraylist.add(n); } //fill the grids with images for(int i=0; i<arraylist.size(); i++){ //select random image from arraylist int index = rand.nextInt (pictures.size()); String fileName = (String) pictures.get(index ); //find the image file icon = createImageIcon(fileName); //save the file in a new file file.add(fileName); //rescaled the image int x = rand.nextInt(50)+50; int y = rand.nextInt(50)+50; Image image = icon.getImage().getScaledInstance(x,y,Image.SCALE_SMOOTH); icon.setImage(image); //remove empty label and replace it with an image int one = (Integer) arraylist.get(i); pDraw.remove(one); final JLabel label; pDraw.add(label,one); }

  • Basic CHMOD restriction

    - by Marshall Mathews
    i have an uploads folder on my website. What i want to do is restrict users from accessing like i dont want them to go to www.mysite.com/uploads/ and see the files in there and it should show forbidden, but they should be able to download via my website, for example www.mysite.com/downloads.php?id=1 If thats not possible, how can i atleast not show them the directory index on /uploads How is it that file sharing websites does this? An htaccess with deny from all stops php from accessing the file as well Please tell me a solution if you would know, i googled and asked on irc a few days ago about this issue, its pretty confusing to me.

  • How to boot Windows XP using the image file(not the extracted image file)

    - by Nrew
    Is it possible to boot from an iso image file itself. Because when you burn it, it gets extracted. Because in linux you can just place the .iso file in a removable media and boot from it without extracting. Is it possible to make something like that in windows? What I'm saying is related to this: http://wintoflash.com/forum/viewtopic.php?f=5&t=312 Something like creating a flash drive which has the ability to install multiple os. They have something like this in pendrivelinux but I can't find it anymore. But that boot manager can only install linux. And other live cd's used in cleaning the system. That's why I'm asking if its possible to make a custom windows xp or windows 7 installer so that the image file alone can boot.

  • What would prevent a .BAT file from being run on a mapped drive?

    - by JBurace
    In WinXP SP3, I have a .BAT file on a mapped drive. When I try to run this .BAT file (or even right click-edit) it gives me: --------------------------- Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item. --------------------------- OK --------------------------- This happens with any .BAT file, no matter what is within the file. If the file is on my local computer (like C:) it will run just fine. If someone else runs it from another computer (on the same mapped drive), it runs just fine. I have full permissions on the drive; I can edit/delete/save/write/create in that folder and/or .BAT file and I've ruled out permissions being the issue. It seems like a security prevention, but I can't tell what it would be. It would have to be something on my PC, but I don't use any 3rd party software. What would cause this error?

But when i use the ftp command in command prompt and try to transfer using "send" command i get an error "553 could not create file". This also happens from SSIS package. I'm not in control of the FTP server but if anyone can provide a solution I can pass it to the admin or anything to be done from my end?

  • .NET 4.0 Dynamic object used statically?

    - by Kevin Won
    I've gotten quite sick of XML configuration files in .NET and want to replace them with a format that is more sane. Therefore, I'm writing a config file parser for C# applications that will take a custom config file format, parse it, and create a Python source string that I can then execute in C# and use as a static object (yes that's right--I want a static (not the static type dyanamic) object in the end). Here's an example of what my config file looks like: // my custom config file format GlobalName: ExampleApp Properties { ExternalServiceTimeout: "120" } Python { // this allows for straight python code to be added to handle custom config def MyCustomPython: return "cool" } Using ANTLR I've created a Lexer/Parser that will convert this format to a Python script. So assume I have that all right and can take the .config above and run my Lexer/Parser on it to get a Python script out the back (this has the added benefit of giving me a validation tool for my config). By running the resultant script in C# // simplified example of getting the dynamic python object in C# // (not how I really do it) ScriptRuntime py = Python.CreateRuntime(); dynamic conf = py.UseFile("conftest.py"); dynamic t = conf.GetConfTest("test"); I can get a dynamic object that has my configuration settings. I can now get my config file settings in C# by invoking a dynamic method on that object: //C# calling a method on the dynamic python object var timeout = t.GetProperty("ExternalServiceTimeout"); //the config also allows for straight Python scripting (via the Python block) var special = t.MyCustonPython(); of course, I have no type safety here and no intellisense support. I have a dynamic representation of my config file, but I want a static one. I know what my Python object's type is--it is actually newing up in instance of a C# class. But since it's happening in python, it's type is not the C# type, but dynamic instead. What I want to do is then cast the object back to the C# type that I know the object is: // doesn't work--can't cast a dynamic to a static type (nulls out) IConfigSettings staticTypeConfig = t as IConfigSettings Is there any way to figure out how to cast the object to the static type? I'm rather doubtful that there is... so doubtful that I took another approach of which I'm not entirely sure about. I'm wondering if someone has a better way... So here's my current tactic: since I know the type of the python object, I am creating a C# wrapper class: public class ConfigSettings : IConfigSettings that takes in a dynamic object in the ctor: public ConfigSettings(dynamic settings) { this.DynamicProxy = settings; } public dynamic DynamicProxy { get; private set; } Now I have a reference to the Python dynamic object of which I know the type. So I can then just put wrappers around the Python methods that I know are there: // wrapper access to the underlying dynamic object // this makes my dynamic object appear 'static' public string GetSetting(string key) { return this.DynamicProxy.GetProperty(key).ToString(); } Now the dynamic object is accessed through this static proxy and thus can obviously be passed around in the static C# world via interface, etc: // dependency inject the dynamic object around IBusinessLogic logic = new BusinessLogic(IConfigSettings config); This solution has the benefits of all the static typing stuff we know and love while at the same time giving me the option of 'bailing out' to dynamic too: // the DynamicProxy property give direct access to the dynamic object var result = config.DynamicProxy.MyCustomPython(); but, man, this seems rather convoluted way of getting to an object that is a static type in the first place! Since the whole dynamic/static interaction world is new to me, I'm really questioning if my solution is optimal or if I'm missing something (i.e. some way of casting that dynamic object to a known static type) about how to bridge the chasm between these two universes.
