  • no instance of overloaded function getline c++

    - by Dave
    I'm a bit confused as to what i have incorrect with my script that is causing this error. I have a function which calls a fill for game settings but it doesn't like my getline. Also i should mention these are the files i have included for it: #include <fstream> #include <cctype> #include <map> #include <iostream> #include <string> #include <algorithm> #include <vector> using namespace std;' This is what i have: std::map<string, string> loadSettings(std::string file){ ifstream file(file); string line; std::map<string, string> config; while(std::getline(file, line)) { int pos = line.find('='); if(pos != string::npos) { string key = line.substr(0, pos); string value = line.substr(pos + 1); config[trim(key)] = trim(value); } } return (config); } The function is called like this from my main.cpp //load settings for game std::map<string, string> config = loadSettings("settings.txt"); //load theme for game std::map<string, string> theme = loadSettings("theme.txt"); Where did i go wrong ? Please help! The error: settings.h(61): error C2784: 'std::basic_istream<_Elem,_Traits> &std::getline(std::basic_istream<_Elem,_Traits> &&,std::basic_string<_Elem,_Traits,_Alloc> &)' : could not deduce template argument for 'std::basic_istream<_Elem,_Traits> &&' from 'std::string'

  • Redemption using filter on a custom datetime field in contacts.

    - by Spitje
    Hello, I'm having a problem using a filter on a custom date in contacts. RDOItems Contacts = null; string strSearch = string.Empty; strSearch = AddQuotes("http://schemas.microsoft.com/mapi/string/{01234567-8901-2345-C678-901234567801}/CustomFieldString"); strSearch += " <> '' "; strSearch += " AND "; strSearch += AddQuotes("http://schemas.microsoft.com/mapi/string/{01234567-8901-2345-C678-901234567802}/CustomFieldDate"); strSearch += " < "; strSearch += "'2010-04-28 18:00'"; Contacts = (RDOItems)synContacts.Items.Restrict(strSearch) When i use only the first part of the filter (CustomFieldString) i get the right contacts, but when i expand the filter with the datetime field no contacts are returned. Thanks, Spitje

  • Automatically decorating every instance method in a class

    - by max
    I want to apply the same decorator to every method in a given class, other than those that start and end with __. It seems to me it should be doable using a class decorator. Are there any pitfalls to be aware of? Ideally, I'd also like to be able to: disable this mechanism for some methods by marking them with a special decorator enable this mechanism for subclasses as well enable this mechanism even for methods that are added to this class in runtime [Note: I'm using Python 3.2, so I'm fine if this relies on features added recently.] Here's my attempt: _methods_to_skip = {} def apply(decorator): def apply_decorator(cls): for method_name, method in get_all_instance_methods(cls): if (cls, method) in _methods_to_skip: continue if method_name[:2] == `__` and method_name[-2:] == `__`: continue cls.method_name = decorator(method) return apply_decorator def dont_decorate(method): _methods_to_skip.add((get_class_from_method(method), method)) return method Here are things I have problems with: how to implement get_all_instance_methods function not sure if my cls.method_name = decorator(method) line is correct how to do the same to any methods added to a class in runtime how to apply this to subclasses how to implement get_class_from_method

  • Best way to test instance methods without running __init__

    - by KenFar
    I've got a simple class that gets most of its arguments via init, which also runs a variety of private methods that do most of the work. Output is available either through access to object variables or public methods. Here's the problem - I'd like my unittest framework to directly call the private methods called by init with different data - without going through init. What's the best way to do this? So far, I've been refactoring these classes so that init does less and data is passed in separately. This makes testing easy, but I think the usability of the class suffers a little. EDIT: Example solution based on Ignacio's answer: import types class C(object): def __init__(self, number): new_number = self._foo(number) self._bar(new_number) def _foo(self, number): return number * 2 def _bar(self, number): print number * 10 #--- normal execution - should print 160: ------- MyC = C(8) #--- testing execution - should print 80 -------- MyC = object.__new__(C) MyC._bar(8)

  • Quering computed fields in GORM

    - by Tihom
    I am trying to query the following HQL using GORM: MailMessage.executeQuery("toId, count(toId) from (SELECT toId, threadId FROM MailMessage as m WHERE receiveStatus = '$u' GROUP BY threadId, toId) as x group by x.toId") The problem is that count(toId) is a computed field doesn't exist in MailMessage and that I am using a subquery. I get the following error: java.lang.IllegalArgumentException: node to traverse cannot be null! Ideally, I would like to use a generic executeQuery which will return data of anytype. Is there such a thing?

  • I need to recover an instance of an activity

    - by Bilthon
    Well.. the title is pretty descriptive, I have a bunch of tab activities (which I implemented myself, didn't want to use the tabviews with activities inside them), so It's basically 5 activities calling each other every time the user clicks on the tabs displayed as a row of LinearLayouts at the bottom of the screen. The thing is that the way I do it now, everytime the user jumps from one activity to another, a new activity is created and launched. Of course, I can see I'm wasting resources this way. So what I would like to do is to create every activity only once; and then if the user wants to go back to the previous (or any one that was already created and is probably paused) just check on some kind of list or array to see if the activity can be recovered and only in the case it can't; to lauch a new one. My question is, how can I check this? should I save the intents? and how to recover the activities afterwards? I'm kind of new with java. Greetings Nelson R. Perez

  • Debugging instance of another thread altering my data

    - by Mick
    I have a huge global array of structures. Some regions of the array are tied to individual threads and those threads can modify their regions of the array without having to use critical sections. But there is one special region of the array which all threads may have access to. The code that accesses these parts of the array needs to carefully use critical sections (each array element has its own critical section) to prevent any possibility of two threads writing to the structure simultaneously. Now I have a mysterious bug I am trying to chase, it is occurring unpredictably and very infrequently. It seems that one of the structures is being filled with some incorrect number. One obvious explanation is that another thread has accidentally been allowed to set this number when it should be excluded from doing so. Unfortunately it seems close to impossible to track this bug. The array element in which the bad data appears is different each time. What I would love to be able to do is set some kind of trap for the bug as follows: I would enter a critical section for array element N, then I know that no other thread should be able to touch the data, then (until I exit the critical section) set some kind of flag to a debugging tool saying "if any other thread attempts to change the data here please break and show me the offending patch of source code"... but I suspect no such tool exists... or does it? Or is there some completely different debugging methodology that I should be employing.

  • Populate table fields on query execution

    - by Jason
    I'm trying to build an ASP site that populates a Table based on the results of a selection in a ListBox. In order to do this, I've created a GridView table inside a div element. Currently the default behavior is to show all the items in the specified table in sortable order. However, I'd like to refine this further to allow for display of matches based on the results from the ListBox selection, but am not sure how to execute this. The ListBox fires off a OnSelectionChanged event to the method defined below and the GridView element is defined as <asp:GridView ID="dataListings" runat="server" AllowSorting="True" AutoGenerateColumns="False" DataSourceID="LinqDataSource1" OnDataBinding="ListBox1_SelectedIndexChanged"> protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e) { int itemSelected = selectTopics.SelectedIndex; string[] listing = null; switch (itemSelected)//assign listing the array of course numbers { case 0: break; case 1: listing = arts; break; case 2: listing = currentEvents; break; .... More cases here default: listing = arts; break; } using (OLLIDBDataContext odb = new OLLIDBDataContext()) { var q = from c in odb.tbl_CoursesAndWorkshops where listing.Contains(c.tbl_Course_Description.tbl_CoursesAndWorkshops.course_workshop_number) select c; dataListings.DataSource = q; dataListings.DataBind(); } } However, this method never gets fired. I can see a request being made when changing the selection, but setting a breakpoint at the method declaration does nothing at all. Based on this, setup, I have three related questions What do I need to modify to get the OnSelectionChanged event handler to fire? How can I alter the GridView area to be empty on page load? How do I send the results from the dataListings.DataBind() execution to show in the GridView?

  • Accessing custom user profile fields in CCK

    - by Nick Lowman
    I'm probably going about this the wrong way but... I’ve added a field to the User Profile called profile_real_name which is required by the user. Is there a way to access the details in CCK? For example in CCK when creating a new field I can access the user’s username with the ‘User reference’ Field type and setting the ‘Widget type’ to ‘Autocomplete text field’. Can I do the same with my real name field? Many thanks

Is there any way ? Even just to edit hash code. UPDATE: https://github.com/mrjoes/flask-admin/issues/78

  • GAE update different fields of the same entity

    - by bach
    Hi, UserA and UserB are changing objectA.filedA objectA.filedB respectively and at the same time. Because they are not changing the same field one might think that there are no overlaps. Is that true? or the implementation of pm.makePersistnace() actually override the whole object... good to know...

  • Iteratively creating multiple file input fields in Rails

    - by David
    I have a column of product views in a database (e.g. top, bottom, front, back). I'm trying to generate a series of file inputs to allow the user to upload an image for each view. This is the result I'm after: ... <label>Top</label> <input type="file" name="image[Top]"><br> <label>Bottom</label> <input type="file" name="image[Bottom]"><br> <label>Front</label> <input type="file" name="image[Front']"><br> ... This is what I'm trying: <%= views = View.order('name ASC').all.map { |view| [view.name, view.id] } %> <%= views.each { |view| label(view); file_field('image', view) } %> However, all this does is print out the views array a couple of times. Hopefully you Rails experts can point me in the right direction. (I apologize in advance if I'm butchering Ruby.)

  • Right design to validate attributes of a class instance

    - by systempuntoout
    Having a simple Python class like this: class Spam(object): __init__(self, description, value): self.description = description self.value = value Which is the correct approach to check these constraints: "description cannot be empty" "value must be greater than zero" Should i: 1.validate data before creating spam object ? 2.check data on __init__ method ? 3.create an is_valid method on Spam class and call it with spam.isValid() ? 4.create an is_valid static method on Spam class and call it with Spam.isValid(description, value) ? 5.check data on setters? 6.... Could you recommend a well designed\Pythonic\not verbose (on class with many attributes)\elegant approach?

  • How a web app identify if a click came from another web app via code?

    - by Diego
    Hi, we have a web application that users can take online reports from ou ERP system data... And we have another web application that is used by our teachers and employees. We can't change the ERP web app because its a closed DLL, in this case we made some extended functionality in our custom internal web app and we are willing to put this functionality on the "menu" of the ERP web app. I need to integrate the two applications in the following way: When I click in the menu of the ERP web app, I want that our internal web app assert that the click have come from our ERP web app and not typed in the URL, this is possible?

  • Factory vs instance constructors

    - by Neil N
    I can't think of any reasons why one is better than the other. Compare these two implementations: public class MyClass { public myClass(string fileName) { // some code... } } as opposed to: public class MyClass { private myClass(){} public static Create(string fileName) { // some code... } } There are some places in the .Net framework that use the static method to create instances. At first I was thinking, it registers it's instances to keep track of them, but regular constructors could do the same thing through the use of private static variables. What is the reasoning behind this style?

  • Extending jQuery Form Validation Script for new form fields

    - by user982124
    I have a simple HTML form that originally was a series of Questions (A1 to A5 and B1 to B3) with yes/no radio buttons like this: <tr> <td width="88%" valign="top" class="field_name_left">A1</td> <td width="12%" valign="top" class="field_data"> <input type="radio" name="CriteriaA1" value="Yes">Yes<input type="radio" name="CriteriaA1" value="No">No</td> </tr> The user could only answer either the A series of questions OR either the B series of questions, but not both. Also they must complete all questions in either the A or B series. I now have an additional series of questions - C1 to C6 - and need to extend my validation scripts to ensure the user enters either A, B or C and answers all questions within each series. My original script for just the A and B looks like this: $(function() { $("#editRecord").submit(function(){ // is anything checked? if(!checkEmpty()){ $("#error").html("Please check something before submitting"); //alert("nothing Checked"); return false; } // Only A _OR_ B if(isAorB()){ $("#error").html("Please complete A or B, not both"); //alert("please complete A or B, not both"); return false; }; // all A's or all B's if(allAorBChecked()){ $("#error").html("It appears you have not completed all questions"); //alert("missing data"); return false; }; if(haveNo()){ // we're going on, but sending "type = C" } //alert("all OK"); return true; }); }); function checkEmpty(){ var OK = false; $(":radio").each(function(){ if (this.checked){ OK = true; } }); return OK; } function isAorB(){ var OK = false; var Achecked = false; var Bchecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); // if we have an A checked remember it if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } if(Achecked && theChar == "B" && !Bchecked){ if(this.checked){ Bchecked = true; } } if (Achecked && Bchecked){ OK = true; } }); return OK; } function allAorBChecked(){ var notOK = false; var Achecked = false; $(":radio").each(function(){ // skip through to see if we're doing A's or B's var theChar=this.name.charAt(8); // check the A's if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } }); if(Achecked){ // set the input to A $("#type").val("A"); // check _all_ a's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "A"){ if (this.name == thisName && !thisChecked){ // Yes wasn't checked - is No? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); }else{ // set the input to B $("#type").val("B"); // check _all_ b's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "B"){ if (this.name == thisName && !thisChecked){ // A wasn't checked - is B? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); } return notOK; } function haveNo(){ var thisName; var notOK = false; $(":radio").each(function(){ var checked = this.checked; if (this.name == thisName){ //Is this checked if(checked){ notOK = true; $("#type").val("C"); } } thisName = this.name; }); return notOK; } This worked well but I'm completely stuck at extending it to include the C series. I now have to check that the user hasn't answered any A and B, A and C and B and C questions. Everything I've tried fails to validate. Here's where I'm at right now with my new script: $(function() { $("#editRecord").submit(function(){ // is anything checked? if(!checkEmpty()){ $("#error").html("Please check something before submitting"); //alert("nothing Checked"); return false; } // Only A or B or C if(isAorBorC()){ $("#error").html("Please complete A or B or C, not both"); //alert("please complete A or B, not both"); return false; }; // all A's or all B's or all C's if(allAorBorCChecked()){ $("#error").html("It appears you have not completed all questions"); //alert("missing data"); return false; }; if(haveNo()){ // we're going on, but sending "type = C" } //alert("all OK"); return true; }); }); function checkEmpty(){ var OK = false; $(":radio").each(function(){ if (this.checked){ OK = true; } }); return OK; } function isAorBorC(){ var OK = false; var Achecked = false; var Bchecked = false; var Cchecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); // if we have an A checked remember it if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } if(theChar == "B" && this.checked && !Achecked){ Bchecked = true; } if(theChar == "C" && this.checked && !Achecked){ Cchecked = true; } if(Achecked && theChar == "B" && !Bchecked){ if(this.checked){ Bchecked = true; } } if(Achecked && theChar == "C" && !Cchecked){ if(this.checked){ Cchecked = true; } } if(Bchecked && theChar == "C" && !Cchecked){ if(this.checked){ Cchecked = true; } } if (Achecked && Bchecked){ OK = true; } if (Achecked && CBchecked){ OK = true; } if (Bchecked && Cchecked){ OK = true; } }); return OK; } function allAorBorCChecked(){ var notOK = false; var Achecked = false; $(":radio").each(function(){ // skip through to see if we're doing A's or B's var theChar=this.name.charAt(8); // check the A's if(theChar == "A" && this.checked && !Achecked){ Achecked = true; } }); if(Achecked){ // set the input to A $("#type").val("A"); // check _all_ a's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "A"){ if (this.name == thisName && !thisChecked){ // Yes wasn't checked - is No? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); }elseif{ // set the input to B $("#type").val("B"); // check _all_ b's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "B"){ if (this.name == thisName && !thisChecked){ // A wasn't checked - is B? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); } return notOK; } }else{ // set the input to C $("#type").val("C"); // check _all_ c's are checked var thisName; var thisChecked = false; $(":radio").each(function(){ var theChar=this.name.charAt(8); var checked = this.checked; if (theChar == "C"){ if (this.name == thisName && !thisChecked){ // A wasn't checked - is B? if(!checked){ notOK = true; } } thisChecked = checked; thisName = this.name; } }); } return notOK; } function haveNo(){ var thisName; var notOK = false; $(":radio").each(function(){ var checked = this.checked; if (this.name == thisName){ //Is this checked if(checked){ notOK = true; $("#type").val("C"); } } thisName = this.name; }); return notOK; } Anyone see what I'm doing wrong?

So how can i out the constraint (maybe in the django models or wherever possible) that poll and user-id both should not be the same for any entry but like the same user can vote for various different polls once and obviously various users can vote for the same poll. I hope I am clear.

I have looked at the find() method, but i'm not sure you can pass a boolean method in instead of a searched item parameter if that makes sense.
