  • Simple regex question (C#, MS SQL)

    - by Vytas999
    Hello, I have some Regex, it looks like this: string regexForDrop = @"^((%27)|'|(\-\-))\s*(d|%64|%44)(r|%72|%52)(o|%6F|%4F)(p|%70|%50)$"; It works fine, when i write to the input "--drop", but it does not works, when i write "drop table users" or something like that. I need that it would be working, no matter what comes after "--drop". How i can implement that? Thanks

  • EntityFramework .net 4 Update entity with a simple method

    - by Dennis Larsen
    I was looking at this SO question: http://stackoverflow.com/questions/1168215/ado-net-entity-framework-update-only-certian-properties-on-a-detached-entity. This was a big help for me. I know now that I need to attach an entity before making my changes to it. But how can do I do this: I have an MVC website, a Customer Update Page with fields: ID, Name, Address, etc. My MVC is parsing this into a Customer entity. How do I do the following: Update my entity and Save the changes to it. Catch the exception if my changes have been made since I loaded my entity.

  • ruby on rails-Problem with the selection form helper

    - by winter sun
    Hello I have a form in witch users can add their working hours view them and edit them (All in one page). When adding working hours the user must select a project from a dropdown list. In case the action is adding a new hour record the dropdown field should remain empty (not selected) in case the action is edit the dropdown field should be selected with the appropriate value. In order to overcome this challenge I wrote the following code <% if params[:id].blank?%> <select name="hour[project_id]" id="hour_project_id"> <option value="nil">Select Project</option> <% @projects.each do|project|%> <option value="<%=project.id %>"><%=project.name%></option> <% end%> </select> <% else %> <%= select('hour','project_id', @projects.collect{|project|[project.name,project.id]},{:prompt => 'Select Project'})%> <% end %> So in case of save action I did the dropdown list only with html, and in case of edit action I did it with the collect method. It works fine until I tried to code the errors. The problem is that when I use the error method: validates_presence_of :project_id it didn't recognize it in the html form of the dropdown list and don’t display the error message (its working only for the dropdown with the collect method). I will deeply appreciate your instructions and help in this matter

  • Simple time profiling - strange times

    - by Gacek
    I'm trying to profile my code to check how long it takes to execute some parts of my code. I've wrapped my most time-consuming part of the code in something like that: DateTime start = DateTime.Now; ... ... // Here comes the time-consuming part ... Console.WriteLine((DateTime.Now - start).Miliseconds); The program is executing this part of code for couple of seconds (about 20 s) but in console I get the result of something about 800 miliseconds. Why is that so? What am I doing wrong?

  • C# app running as either Windows Form or as Console Application

    - by Aeolien
    I am looking to have one of my Windows Forms applications be run programmatically—from the command line. In preparation, I have separated the logic in its own class from the Form. Now I am stuck trying to get the application to switch back and forth based on the presence of command line arguments. Here is the code for the main class: static class Program { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { string[] args = Environment.GetCommandLineArgs(); if (args.Length > 1) // gets passed its path, by default { CommandLineWork(args); return; } Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } private static void CommandLineWork(string[] args) { Console.WriteLine("It works!"); Console.ReadLine(); } where Form1 is my form and the It works! string is just a placeholder for the actual logic. Right now, when running this from within Visual Studio (with command line arguments), the phrase It works! is printed to the Output. However, when running the /bin/Debug/Program.exe file (or /Release for that matter) the application crashes. Am I going about this the right way? Would it make more sense (i.e. take less developer time) to have my logic class be a DLL that gets loaded by two separate applications? Or is there something entirely different that I'm not aware of? Thanks in advance!

  • Simple sound effect loop using AudioToolKit

    - by Typeoneerror
    I've created a few sounds for use in my game. I can play them at certain events without issue: // create sounds CFBundleRef mainBundle; mainBundle = CFBundleGetMainBundle(); _soundFileShake = CFBundleCopyResourceURL(mainBundle, CFSTR("shake"), CFSTR("wav"), NULL); AudioServicesCreateSystemSoundID(_soundFileShake, &_soundIdShake); // later... AudioServicesPlaySystemSound(_soundIdShake); The game has a mechanism which allows you to shake the device to activate some functionality. I've got the shaking code done so I get get a "shaking started" and "shaking ended" message to my game. What I need to have happen is start playing "shave.wav" when shaking starts and loop it until it stops. Is there a way to do this with AudioToolbox/AudioServices? How could I do this if not?

  • Server side form validation and POST data

    - by tomcritchlow
    Hi, I have a user input form here: http://www.7bks.com/create (Google login required) When you first create a list you are asked to create a public username. Unfortuantely currently there is no constraint to make this unique. I'm working on the code to enforce unique usernames at the moment and would like to know the best way to do it. Tech details: appengine, python, webapp framework What I'm planning is something like this: first the /create form posts the data to /inputlist/ (this is the same as currently happens) /inputlist/ queries the datastore for the given username. If it already exists then redirect back to /create display the /create page with all the info previously but with an additional error message of "this username is already taken" My question is: Is this the best way of handling server side validation? What's the best way of storing the list details while I verify and modify the username? As I see it I have 3 options to store the list details but I'm not sure which is "best": Store the list details in the session cookie (I am using GAEsessions for cookies) Define a separate POST class for /create and post the list data back from /inputlist/ to the /create page (currently /create only has a GET class) Store the list in the datastore, even though the username is non-unique. Thank you very much for your help :) I'm pretty new to python and coding in general so if I've missed something obvious my apologies. Tom PS - I'm sure I can eventually figure it out but I can't find any documentation on POSTing data using the webapp appengine framework which I'd need in order to do solution 2 above :s maybe you could point me in the right direction for that too? Thanks! PPS - It's a little out of date now but you can see roughly how the /create and /inputlist/ code works at the moment here: 7bks.com Gist

  • Looking for app to work fluidly with CSV data in graph form

    - by Aszurom
    It often occurs to me that if I had a good tool for viewing CSV data in graphical format, and comparing two sets of numbers to each other, I could do a great deal of meaningful trend watching and data interpretation. For example, perfmon can output quite a lot of data about a server into a CSV file, but there's no good way to view it. A lot of scripts could/have been written that would populate CSV files. I could write these all day long. My problem is that I need a great viewer. I've seen quite a few things that will take a CSV file and after a lot of tweaking and user adjustment produce a static gif/png image. A static image doesn't do me a lot of good, because I have to look at it, then re-calibrate the parameters of the program, regenerate the image, repeat. That sucks. I could do this in Excel. Ideally, I would want a FLUID graph viewer. On the fly, I can adjust how much of my timeline I'm viewing. I could adjust the scaling so that one big spike doesn't make 99.9% of the data an unreadable line across the bottom of the X axis. Stuff like that. I should be able to say "show me CSV column 3 and column 5 as graphs. Show me the data scaled for 20 or 150 entries, and let me slide that window up and down the column of data. Auto scale to fit 95% of data within the Y axis and let crazy spikes go off the screen." Maybe I'm terribly spoiled by how you can drag, zoom, and slide data around on my iPad. I want to be able to view a spreadsheet of data with that fluidity and not have to guess at what sort of static snapshot I want to create from it. I don't want to have to make a study of how to tweak some data plotting program to let me import my file and do what I could just do in Excel. I want to scale, zoom, and transform my graph on the fly and then export a snapshot of it once I have it the way I want it. Is there anything out there that fills this need? I'll take linux, osx, win32 or even iOS suggestions.

  • Simple bad merge scenario in mercurial

    - by user281180
    I have created a repository AAA and another BBB. In AAA I have created a file A with the values a1, a2, a3 and commit In BBB I have created a file B with the values b1, b2, b3, commit and export a bundle. I add the bundle in AAA and merge. I make a change in B, and write b33 in AAA and another change in B and write b23 in BBB. and commit both. I create bundle of BBB and add the bundle in AAA. I do a merge. Now I decide to revert to the revert to step 2. I no more want to have the merge of 4. changes done in B as they were bad merges. Now I want to add the bundle of 3 but I can see that it can`t see any changes anymore. Why? How can I do the merge once more?

  • Cocoa -- getting a simple NSImageView to work

    - by William Jockusch
    I am confused about why this code does not display any image: In the app delegate: - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { NSRect rect = window.frame; rect.origin.x = 0; rect.origin.y = 0; BlueImageView *blueImageView = [[BlueImageView alloc]initWithFrame:rect]; window.contentView = blueImageView; // also tried [window.contentView addSubview: blueImageView]; } BlueImageView.h: @interface BlueImageView : NSImageView { } @end BlueImageView.m: @implementation BlueImageView - (id)initWithFrame:(NSRect)frame { self = [super initWithFrame:frame]; if (self) { [self setImage: [NSImage imageNamed:@"imagefile.png"]]; NSAssert(self.image, @""); NSLog (@"Initialized"); } return self; } - (void)drawRect:(NSRect)dirtyRect { } @end The file imagefile.png exists. The NSAssert is not causing an exception. The NSLog is firing. But no image shows up in the window.

  • Writing a simple incrementing counter in rails

    - by Trip
    For every Card, I would like to attach a special number to them that increments by one. I assume I can do this all in the controller. def create @card = Card.new(params[:card]) @card.SpecNum = @card.SpecNum ++ ... end Or. I can be blatantly retarded. And maybe the best bet is to add an auto-incremement table to mysql. The problem is the number has to start at a specific number, 1020. Any ideas?

  • Simple Database normalization question...

    - by user365531
    Hi all, I have a quick question regarding a database that I am designing and making sure it is normalized... I have a customer table, with a primary key of customerId. It has a StatusCode column that has a code which reflects the customers account status ie. 1 = Open, 2 = Closed, 3 = Suspended etc... Now I would like to have another field in the customer table that flags whether the account is allowed to be suspended or not... certain customers will be automatically suspended if they break there trading terms... others not... so the relevant table fields will be as so: Customers (CustomerId(PK):StatusCode:IsSuspensionAllowed) Now both fields are dependent on the primary key as you can not determine the status or whether suspensions are allowed on a particular customer unless you know the specific customer, except of course when the IsSuspensionAllowed field is set to YES, the the customer should never have a StatusCode of 3 (Suspended). It seems from the above table design it is possible for this to happen unless a check contraint is added to my table. I can't see how another table could be added to the relational design to enforce this though as it's only in the case where IsSuspensionAllowed is set to YES and StatusCode is set to 3 when the two have a dependence on each other. So after my long winded explanation my question is this: Is this a normalization problem and I'm not seeing a relational design that will enforce this... or is it actually just a business rule that should be enforced with a check contraint and the table is in fact still normalized. Cheers, Steve

  • JSON and WebOS simple example?

    - by user558361
    I have been following this tutorial http://tinyurl.com/327p325 which has been GREAT up until this point where I can't get his code to work. I get the list working with static items but I can't get it to work with the json items. I've tried to simplify it with what I really want it to do to try and debug what is wrong (also if someone could please tell me how to view the Mojo log that would be awesome) In the tutorial he has to use the yahoo service to convert the site into json data, while the site I want to interact with already has json data generated so this is what I have PageAssistant.prototype.setup = function() { this.myListModel = { items : [] }; this.myListAttr = { itemTemplate: "page/itemTemplate", renderLimit: 20, }; this.controller.setupWidget("MyList",this.myListAttr,this.myListModel); this.controller.setupWidget("search_divSpinner", { spinnerSize : "large" }, { spinning: true } ); }; PageAssistant.prototype.activate = function(event) { this.getData(); }; PageAssistant.prototype.getData = function () { // the spinner doesn't show up at all $("search_divScrim").show(); var url = "http://www.website.com/.json"; var request = new Ajax.Request(url, { method: 'get', asynchronous: true, evalJSON: "false", onSuccess: this.parseResult.bind(this), on0: function (ajaxResponse) { // connection failed, typically because the server is overloaded or has gone down since the page loaded Mojo.Log.error("Connection failed"); }, onFailure: function(response) { // Request failed (404, that sort of thing) Mojo.Log.error("Request failed"); }, onException: function(request, ex) { // An exception was thrown Mojo.Log.error("Exception"); }, }); } PageAssistant.prototype.parseResult = function (transport){ var newData = []; var theStuff=transport.responseText; try { var json = theStuff.evalJSON(); } catch(e) { Mojo.Log.error(e); } // this is where I believe I am wrong for (j=0;j < json.data.count;j++) { var thread=json.data.children[j]; newData[j] = { title: thread.data.author }; } this.myListModel["items"] = newData; this.controller.modelChanged(this.myListModel , this); $("search_divScrim").hide(); } So where I commented that I believe I am wrong I am just trying to get the title out of this json data { kind: Listing data: { children: [ { kind: food data: { author: Foodmaster hidden: false title: You should eat this } }, // then it repeats with the kind: and data Anyone see where I went wrong? I would like to know how to view the log as I have log events but can't figure out where to look to see if any of them are being thrown.

  • Form With Quantity doesn't seem to submit

    - by Karl Entwistle
    Hey guys, I've been trying to understand the documentation and find an example, but I'm at a loss. This is just a submit form within the cart for updating the quantity. However, the updated quantity is not getting saved to the database -- it always makes the quantity 0. Please help.

  • NSString simple pattern matching

    - by SirRatty
    Hi all, Mac OS 10.6, Cocoa project, 10.4 compatibility required. (Please note: my knowledge of regex is quite slight) I need to parse NSStrings, for matching cases where the string contains an embedded tag, where the tag format is: [xxxx] Where xxxx are random characters. e.g. "The quick brown [foxy] fox likes sox". In the above case, I need to grab the string "foxy". (Or nil if no tag is found.) Each string will only have one tag, and the tag can appear anywhere within the string, or may not appear at all. Could someone please help with a way to do that, preferably without having to include another library such as RegexKit. Thank you for any help.

  • Boost Date_Time problem compiling a simple program

    - by Andry
    Hello! I'm writing a very stupid program using Boost Date_Time library. int main(int srgc, char** argv) { using namespace boost::posix_time; date d(2002,Feb,1); //an arbitrary date ptime t1(d, hours(5)+nanosec(100)); //date + time of day offset ptime t2 = t1 - minutes(4)+seconds(2); ptime now = second_clock::local_time(); //use the clock date today = now.date(); //Get the date part out of the time } Well I cannot compile it, compiler does not recognize a type... Well I used many features of Boost libs like serialization and more... I correctly built them and, looking in my /usr/local/lib folder I can see that libboost_date_time.so is there (a good sign which means I was able to build that library) When I compile I write the following: g++ -lboost_date_time main.cpp But the errors it showed me when I specify the lib are the same of those ones where I do not specify any lib. What is this? Anyone knows? The error is main.cpp: In function ‘int main(int, char**)’: main.cpp:9: error: ‘date’ was not declared in this scope main.cpp:9: error: expected ‘;’ before ‘d’ main.cpp:10: error: ‘d’ was not declared in this scope main.cpp:10: error: ‘nanosec’ was not declared in this scope main.cpp:13: error: expected ‘;’ before ‘today’
