  • C# : Console.Read() does not get the "right" input

    - by Daemonfire3002nd
    Hi there, I have the following code: The actual problem is the "non-quoted" code. I want to get the player amount (max = 4), but when I ask via Console.Read() and I enter any Int from 1 to 4 I get as value: 48 + Console.Read(). They only thing how I can get the "real" input is using Console.ReadLine(), but this does not give me an Integer, no it returns a string, and actually do not know how to convert String (Numbers) to Integers in C#, because I am new, and because I only found ToString() and not ToNumber. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace eve_calc_tool { class Program { int players; int units; int active_units; int inactive_units; int finished_units; int lastDiceNumber = 0; bool game_state; public static void Main(string[] args) { int count_game = 0; //Console.Title = "Mensch ärger dich nicht"; //Console.WriteLine("\tNeues Spiel wird"); //Console.WriteLine("\t...geladen"); //System.Threading.Thread.Sleep(5000); //Console.Clear(); //Console.WriteLine("Neues Spiel wird gestartet, bitte haben sie etwas Geduld"); //Console.Title = "Spiel " + count_game.ToString(); //Console.Clear(); //string prevText = "Anzahl der Spieler: "; //Console.WriteLine(prevText); string read = Console.ReadLine(); /*Program game = new Program(); game.players = read; game.setPlayers(game.players); if (game.players > 0 && 5 > game.players) { game.firstRound(); }*/ string readagain = read; Console.ReadLine(); } /* bool setPlayers(int amount) { players = amount; if (players > 0) { return true; } else { return false; } } bool createGame() { inactive_units = units = getPlayers() * 4; active_units = 0; finished_units = 0; game_state = true; if (game_state == true) { return true; } else { return false; } } int getPlayers() { return players; } private static readonly Random random = new Random(); private static readonly object syncLock = new object(); public static int RandomNumber(int min, int max) { lock (syncLock) { // synchronize return random.Next(min, max); } } int rollDice() { lastDiceNumber = RandomNumber(1,6); return lastDiceNumber; } int firstRound() { int[] results = new int[getPlayers()]; for (int i = 0; i < getPlayers(); i++) { results[i] = rollDice(); } Array.Sort(results); return results[3]; } */ } }

  • invalid input by the user

    - by TJL
    hey guys so this is my program, I need to notify the user that if hhe/she enters a letter other than w d b or w that is an invalid request. what ive done so far does this, but when i input a number to the dollars_withdraw or dollars_deposit or account_balance the program will do the transaction but also add the "invalid request" before going back to main loop. how do i change it so the program wont do that for numerical inputs for the withdraw deposit and balance?: // Atm machine.cpp : Defines the entry point for the console application. #include <iostream> #include <string> using namespace std; int main () { char user_request; string user_string; double account_balance, dollars_withdraw, dollars_deposit; account_balance = 5000; while(account_balance >0) { cout << "Would you like to [W]ithdraw, [D]eposit, Check your [b]alance or [Q]uit?" << endl; cin >> user_string; user_request= user_string[0]; if(user_request == 'w' || user_request== 'W') { cout << "How much would you like to withdraw?" << endl; cin >> dollars_withdraw; if (dollars_withdraw > account_balance || dollars_withdraw <0) cout << "Invalid transaction" << endl; else account_balance = account_balance - dollars_withdraw; cout << "Your new balance is $" << account_balance << endl; } if (user_request == 'd' || user_request== 'D') { cout << "How much would you like to deposit?" << endl; cin >> dollars_deposit; if (dollars_deposit <0) cout << "Invalid transaction" << endl; else account_balance= account_balance + dollars_deposit; cout << "Your new balance is $" << account_balance << endl; } if(user_request == 'b' || user_request == 'B') { account_balance= account_balance; cout << "Your available balance is $" << account_balance << endl; } if(user_request == 'q' || user_request == 'Q') break; else cout << "Invalid request " << endl; } cout << "Goodbye" << endl; return 0; }

  • MultipleHiddenInput doesn't encode properly over POST?

    - by andrew
    The form looks very simple: class MyForm(forms.Form): ids = forms.MultipleChoiceField(widget=forms.MultipleHiddenInput()) def view(request): ... form = MyForm(initial={'ids': [o.id for o in queryset]}) Which gives me the HTML (which looks good enough): <form method="post" action="/foo/bar/"> <input type="hidden" name="ids" value="7720889" id="id_ids_0"> <input type="hidden" name="ids" value="7717962" id="id_ids_1"> <input type="hidden" name="ids" value="7717807" id="id_ids_2"> <input type="hidden" name="ids" value="7713584" id="id_ids_3"> <input type="hidden" name="ids" value="7712277" id="id_ids_4"> <input type="hidden" name="ids" value="7707475" id="id_ids_5"> <input type="hidden" name="ids" value="7707257" id="id_ids_6"> <input type="hidden" name="ids" value="7705271" id="id_ids_7"> <input type="hidden" name="ids" value="7704338" id="id_ids_8"> <input type="hidden" name="ids" value="7704137" id="id_ids_9"> <input type="hidden" name="ids" value="7695444" id="id_ids_10"> <input type="hidden" name="ids" value="7695242" id="id_ids_11"> <input type="hidden" name="ids" value="7690683" id="id_ids_12"> <input type="hidden" name="ids" value="7690431" id="id_ids_13"> <input type="hidden" name="ids" value="7689035" id="id_ids_14"> <input type="hidden" name="ids" value="7681230" id="id_ids_15"> <input type="hidden" name="ids" value="7679189" id="id_ids_16"> <input type="hidden" name="ids" value="7675315" id="id_ids_17"> <input type="hidden" name="ids" value="7667291" id="id_ids_18"> <input type="hidden" name="ids" value="7661162" id="id_ids_19"> <button type="submit">Test</button> </form> But, in the POST that comes in, I'm only getting one value: <QueryDict: {u'ids': [u'7661162']}> What gives?

  • String Vector program exits before input

    - by kylepayne
    So, I have a project that must add, delete, and print the contents of a vector... the problem is that, when run the program exits before I can type in the string to add to the vector. I commented the function that that portion is in. Thanks! #include <iostream> #include <cstdlib> #include <vector> #include <string> using namespace std; void menu(); void addvector(vector<string>& vec); void subvector(vector<string>& vec); void vectorsize(const vector<string>& vec); void printvec(const vector<string>& vec); void printvec_bw(const vector<string>& vec); int main() { vector<string> svector; menu(); return 0; } //functions definitions void menu() { vector<string> svector; int choice = 0; cout << "Thanks for using this program! \n" << "Enter 1 to add a string to the vector \n" << "Enter 2 to remove the last string from the vector \n" << "Enter 3 to print the vector size \n" << "Enter 4 to print the contents of the vector \n" << "Enter 5 ----------------------------------- backwards \n" << "Enter 6 to end the program \n"; cin >> choice; switch(choice) { case 1: addvector(svector); break; case 2: subvector(svector); break; case 3: vectorsize(svector); break; case 4: printvec(svector); break; case 5: printvec_bw(svector); break; case 6: exit(1); default: cout << "not a valid choice \n"; // menu is structured so that all other functions are called from it. } } void addvector(vector<string>& vec) { string line; int i = 0; cout << "Enter the string please \n"; getline(cin, line); // doesn't prompt for input! vec.push_back(line); } void subvector(vector<string>& vec) { vec.pop_back(); return; } void vectorsize(const vector<string>& vec) { if (vec.empty()) { cout << "vector is empty"; } else { cout << vec.size() << endl; } return; } void printvec(const vector<string>& vec) { for(int i = 0; i < vec.size(); i++) { cout << vec[i] << endl; } return; } void printvec_bw(const vector<string>& vec) { for(int i = vec.size(); i > 0; i--) { cout << vec[i] << endl; } return; }

  • while(true) and loop-breaking - anti-pattern?

    - by KeithS
    Consider the following code: public void doSomething(int input) { while(true) { TransformInSomeWay(input); if(ProcessingComplete(input)) break; DoSomethingElseTo(input); } } Assume that this process involves a finite but input-dependent number of steps; the loop is designed to terminate on its own as a result of the algorithm, and is not designed to run indefinitely (until cancelled by an outside event). Because the test to see if the loop should end is in the middle of a logical set of steps, the while loop itself currently doesn't check anything meaningful; the check is instead performed at the "proper" place within the conceptual algorithm. I was told that this is bad code, because it is more bug-prone due to the ending condition not being checked by the loop structure. It's more difficult to figure out how you'd exit the loop, and could invite bugs as the breaking condition might be bypassed or omitted accidentally given future changes. Now, the code could be structured as follows: public void doSomething(int input) { TransformInSomeWay(input); while(!ProcessingComplete(input)) { DoSomethingElseTo(input); TransformInSomeWay(input); } } However, this duplicates a call to a method in code, violating DRY; if TransformInSomeWay were later replaced with some other method, both calls would have to be found and changed (and the fact that there are two may be less obvious in a more complex piece of code). You could also write it like: public void doSomething(int input) { var complete = false; while(!complete) { TransformInSomeWay(input); complete = ProcessingComplete(input); if(!complete) { DoSomethingElseTo(input); } } } ... but you now have a variable whose only purpose is to shift the condition-checking to the loop structure, and also has to be checked multiple times to provide the same behavior as the original logic. For my part, I say that given the algorithm this code implements in the real world, the original code is the most readable. If you were going through it yourself, this is the way you'd think about it, and so it would be intuitive to people familiar with the algorithm. So, which is "better"? is it better to give the responsibility of condition checking to the while loop by structuring the logic around the loop? Or is it better to structure the logic in a "natural" way as indicated by requirements or a conceptual description of the algorithm, even though that may mean bypassing the loop's built-in capabilities?

  • How do I check if selected value of the DropDown List is not selected in C#?

    - by Sahat
    This code will display the selected value from the drop down list. E.g. if I sellect Item 1 I will get the following output: You have selected Item 1. Label1.Text = "You have selected " + DropDownList1.SelectedValue + "<br />"; But if I don't select anything and click on Submit button, I will get: You have selected What would I need to make it display "You have not selected anything. Please select at least 1 item."

  • ergonomics: what's better; trackball, ergonomic mouse or some other pointing device (a-la touchscree

    - by mauriciopastrana
    So I bit into the hype and recently purchased an apple wireless keyboard and that evil bar-of-soap thing apple makes for a mouse. Couple of hundred dollars later and this is where I begin to worry about RSI. Go figure. Don't get me wrong, this apple mouse is genius and looks pretty as hell, but my right wrist feels tired after a full day's worth of work, so i'm thinking of switching. Anyone out there use a trackball? is this worse? should I get a super-ergonomic mouse instead? I've seen mouse-trackball combos but am not sold, they still elicit the same end-finger behaviour detrimental for RSI, right? I also have a wrist-rest mousepad, but couldn't find one suitable for my keyboard. I've even considered having a small touchscreen where the mousepad should go, no mouse (or alternatively, a usb trackpad). Just looking for ideas, is the trackball better than the mouse? /mp

  • Any screen capture software that captures webcam, microphone inputs too ?

    - by mohanr
    I am going to conduct a user study. Apart from capturing the screen while the user is interacting with the system, I also want to capture the video/audio of the user. Is there any software that in addition to capturing the screen also overlays it with the webcam/microphone inputs. The goal is to capture the complete experience of the user: key/mouse interactions with the system along with their facial/vocal responses. I know that I can maybe run a screen-capture software and also run a software for capturing webcam audio/video alongside and try to sync/overlay both these streams with timestamps. But I am going to be dealing with probably several hundred hours of data. So I am looking for a tool that can streamline the process for me amap and help me keep my sanity at end of the process. Thanks,

  • Hashing words to numbers with respect to definition

    - by thornate
    As part of a larger project, I need to read in text and represent each word as a number. For example, if the program reads in "Every good boy deserves fruit", then I would get a table that converts 'every' to '1742', 'good' to '977513', etc. Now, obviously I can just use a hashing algorithm to get these numbers. However, it would be more useful if words with similar meanings had numerical values close to each other, so that 'good' becomes '6827' and 'great' becomes '6835', etc. As another option, instead of a simple integer representing each number, it would be even better to have a vector made up of multiple numbers, eg (lexical_category, tense, classification, specific_word) where lexical_category is noun/verb/adjective/etc, tense is future/past/present, classification defines a wide set of general topics and specific_word is much the same as described in the previous paragraph. Does any such an algorithm exist? If not, can you give me any tips on how to get started on developing one myself? I code in C++.

  • Java / Groovy Socket - Detecting the socket being closed in a non-blocking way

    - by John Arrowwood
    I'm trying to create a small HTTP proxy that can re-write the request/headers as needed to suit my requirements. If one already exists, please, point me to it. Otherwise... I've written something that ALMOST works. It can do the proxy function, but not the re-write (yet). Problem is, I can't detect when the remote socket has been closed down without doing a blocking read. It is CRITICAL for the functionality of this thing that it be able to detect the socket being closed without blocking. I have SCOURED the Java API documentation, and I can't find ANY indication that it is even possible. Here's what I have: while ( this.inbound.isConnected() && this.outbound.isConnected() ) { try { while ( ( available = readFromClient.available() ) != 0 ) { if ( available > 1024 ) available = 1024 bytesRead = readFromClient.read( buffer, 0, available ) writeToServer.write( buffer, 0, bytesRead ) } while ( ( available = readFromServer.available() ) != 0 ) { if ( available > 1024 ) available = 1024 bytesRead = readFromServer.read( buffer, 0, available ) writeToClient.write( buffer, 0, bytesRead ) } } catch (e) { print e } println "Connected: " + this.inbound.isConnected() println "Bound: " + this.inbound.isBound() println "InputShutdown: " + this.inbound.isInputShutdown() println "OutputShutdown: " + this.inbound.isOutputShutdown() print "\n"; Thread.sleep( 10 ) } The tests for the socket being closed never indicate that the socket was closed. And, as I mentioned, I can't find ANY examples of how to detect the 'END OF FILE' condition on the stream without doing a blocking read. There HAS to be a way. Does anyone here know what it is?

    Hi, I have a shell script which is currently running and was running from past 8 hours. It will complete only by tomorrow evening. At the end of the program, it will print 2 million words to standard output. I am running the program on the screen. I forgot to redirect the output to a file. I know I won't be able to copy the data from the window. Is there a way to output the command to a file. I don't want to restart the program. Any thoughts?? Thank you. Bala

  • ASP.Net WebForms requiredfieldvalidator not working in FireFox?

    - by larryq
    I have a WebForms app that uses a field validator on a dropdownlist. It works in IE but not FireFox. This is pretty straightforward stuff I'm doing. Here are the setups for the dropdown and validator: <asp:DropDownList ID ="dmbFileActNo" runat="server" CssClass="DROPDOWN_MEDIUM" AutoPostBack="True"></asp:DropDownList> <asp:requiredfieldvalidator EnableClientScript="true" id="rfvFileActNo" Display="None" ControlToValidate="dmbFileActNo" Runat="server" InitialValue="-1"></asp:requiredfieldvalidator> I'm running ASP.Net 2.0 on the web server. Javascript is enabled on the FireFox browser-- this problem happens on all FF browsers I've tested, on multiple everyday machines, so I don't believe it's due to a locked down install.

  • According to MSDN ReadFile() Win32 function may incorrectly report read operation completion. When?

    - by Martin Dobšík
    The MSDN states in its description of ReadFile() function (http://msdn.microsoft.com/en-us/library/aa365467%28VS.85%29.aspx): “If hFile is opened with FILE_FLAG_OVERLAPPED, the lpOverlapped parameter must point to a valid and unique OVERLAPPED structure, otherwise the function can incorrectly report that the read operation is complete.” I have some applications that are violating the above recommendation and I would like to know the severity of the problem. I mean the program uses named pipe that has been created with FILE_FLAG_OVERLAPPED, but it reads from it using the following call: ReadFile(handle, &buf, n, &n_read, NULL); That means it passes NULL as the lpOverlapped parameter. That call should not work correctly in some circumstances according to documentation. I have spent a lot of time trying to reproduce the problem, but I was unable to! I always got all data in right place at right time. I was testing only Named Pipes though. Would anybody know when can I expect that ReadFile() will incorrectly return and report successful completion even the data are not yet in the buffer? What would have to happen in order to reproduce the problem? Does it happen with files, pipes, sockets, consoles, or other devices? Do I have to use particular version of OS? Or particular version of reading (like register the handle to I/O completion port)? Or particular synchronization of reading and writing processes/threads? Or when would that fail? It works for me :/ Please help! With regards Martin

  • Best way to implement a Parsing/Editable Richtextbox in WPF

    - by lozzar
    I'm trying to implement (as a prototype initially), a richtextbox control which can be parsed in real time to apply certain formatting options to it. This is being done in WPF so I thought the best way to go about it would be to extend the existing rich text box control. I've run into the issue where it isn't documented well and the examples are quite slow (the ones I found have parse the whole document on every keystroke). The way I've currently decided to go about it is to create a custom Inline element which can hold the formatting tags, and the contents. Hence I only have to parse the current paragraph and the runs in that paragraph for formatting tags. Is there a better way to achieve this? Note this isn't for code/syntax based documents (so AvalonEdit isn't appropriate). Cheers

  • Conditional required field validation in an ASP.net ListView

    - by Jim Dagg
    I'm having a heck of a time trying to figure out how to implement validation in a ListView. The goal is to require the user to enter text in the comments TextBox, but only if the CheckBox is checked. Downside is that these controls are in the EditTemplate of a ListView. Below is a snippet of the relevant code portion of the EditTemplate: <tr style="background-color: #00CCCC; color: #000000"> <td> Assume Risk? <asp:CheckBox ID="chkWaive" runat="server" Checked='<%# Bind("Waive") %>' /> </td> <td colspan="5"> <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Comments required" ControlToValidate="txtComments" /> <asp:TextBox Width="95%" ID="txtComments" runat="server" Text='<%# Eval("Comment") %>'></asp:TextBox> </td> <td> <asp:Button ID="btnSave" runat="server" Text="Save" CommandName="Update" Width="100px" /> </td> </tr> Is there a way to do conditional validation using this method? If not, is there a way I could validate manually in the ItemUpdating event of the Listview, or somewhere else, and on a failure, alert the user of the error via a label or popup alert?
