  • Help with storing/accessing user access roles C# Winforms

    - by user222453
    Hello, firstly I would like to thank you in advance for any assistance provided. I am new to software development and have designed several Client/Server applications over the last 12 months or so, I am currently working on a project that involves a user logging in to gain access to the application and I am looking at the most efficient and "simple" method of storing the users permissions once logged in to the application which can be used throughout restricting access to certain tabs on the main form. I have created a static class called "User" detailed below: static class User { public static int _userID; public static string _moduleName; public static string _userName; public static object[] UserData(object[] _dataRow) { _userID = (int)_dataRow[0]; _userName = (string)_dataRow[1]; _moduleName = (string)_dataRow[2]; return _moduleName; } } When the user logs in and they have been authenticated, I wish to store the _moduleName objects in memory so I can control which tabs on the main form tab control they can access, for example; if the user has been assigned the following roles in the database: "Sales Ledger", "Purchase Ledger" they can only see the relevant tabs on the form, by way of using a Switch - Case block once the login form is hidden and the main form is instantiated. I can store the userID and userName variables in the main form once it loads by means of say for example: Here we process the login data from the user: DataAccess _dal = new DataAccess(); switch (_dal.ValidateLogin(txtUserName.Text, txtPassword.Text)) { case DataAccess.ValidationCode.ConnectionFailed: MessageBox.Show("Database Server Connection Failed!"); break; case DataAccess.ValidationCode .LoginFailed: MessageBox.Show("Login Failed!"); _dal.RecordLogin(out errMsg, txtUserName.Text, workstationID, false); break; case DataAccess.ValidationCode .LoginSucceeded: frmMain frmMain = new frmMain(); _dal.GetUserPrivList(out errMsg,2); //< here I access my DB and get the user permissions based on the current login. frmMain.Show(); this.Hide(); break; default: break; } private void frmMain_Load(object sender, EventArgs e) { int UserID = User._userID; } That works fine, however the _modules object contains mutiple permissions/roles depending on what has been set in the database, how can I store the multiple values and access them via a Switch-Case block? Thank you again in advance.

  • How come you cannot catch Code Contract exceptions?

    - by Finglas
    System.Diagnostics.Contracts.ContractException is not accessiable in my test project. Note this code is purely myself messing around with my shiney new copy of Visual Studio, but I'd like to know what I'm doing wrong. I'm using the professional edition of VS, therefore I do not have static checking. In order to still use code contracts (which I like) I figured the only way my method can work is to catch the exception that is thrown at runtime, but I'm not finding this possible. TestMethod [TestMethod, ExpectedException(typeof(System.Diagnostics.Contracts.ContractException))] public void returning_a_value_less_than_one_throws_exception() { var person = new Person(); person.Number(); } Method public int Number() { Contract.Ensures(Contract.Result<int>() >= 0); return -1; } Error Error 1 'System.Diagnostics.Contracts.ContractException' is inaccessible due to its protection level.

  • Stack Overflow Exploit in C

    - by Fernando Gonzalez
    Hey there guys, the question is actually about stack overflows in C. I have an assigment that I can not get done for the life of me, i've looked at everything in the gdb and I just cant figure it. The question is the following: int i,n; void confused() { printf("who called me"); exit(0); } void shell_call(char *c) { printf(" ***Now calling \"%s\" shell command *** \n",c); system(c); exit(0); } void victim_func() { int a[4]; printf("[8]:%x\n", &a[8]); printf("Enter n: "); scanf("%d",&n); printf("Enter %d HEX Values \n",n); for(i=0;i<n;i++) scanf("%x",&a[i]); printf("Done reading junk numbers\n"); } int main() { printf("ls=736c --- ps = 7370 --- cal = 6c6163\n"); printf("location of confused %x \n", confused); printf("location of shell_call %x \n", shell_call); victim_func(); printf("Done, thank you\n"); } Ok, so I managed to get the first question correctly, which is to arbitrarily call one of the two functions not explicitly called in the main path. By the way, this has to be done while running the program without any modifications. I did this by running the program, setting N to 7, which gets me to the Function Pointer of the victim_func frame, I write a[7] with the memory address of confused or shell_call, and it works. (I have a 64 bit machine, thats why I have to get it to 7, since the EBI pointer is 2 ints wide, instead of 1) My question is the following, how could I control which argument gets passed to the shell_code funcion? ie. how do i write a string to char* c. The whole point is executing unix commands like "ps" etc, by running only the program. I figured writing the EBI pointer with the hex representation of "ps" and setting the arg list of shell_call to that, but that didn't work. I also tried inputing argsv arguments and setting the arg list of shell_call to the arg_list of main, but didnt work either. I think the second version should work, but i believe im not setting the arg list of the new stack frame correctly ( I did it by writing a[8] to 0, since its the first part of the functin pointer, and writing a[9]=736c and a[10]=0000, but its probably not right since those are the parameters of victim_func. So how do i access the parameters of shell_call?

  • Problem with istringstream in C++

    - by helixed
    Hello, I'm sure I'm just doing something stupid here, but I can't quite figure out what it is. When I try to run this code: #include <iostream> #include <string> #include <sstream> using namespace std; int main(int argc, char *argv[]) { string s("hello"); istringstream input(s, istringstream::in); string s2; input >> s2; cout << s; } I get this error: malloc: *** error for object 0x100016200: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug The only thing I can think of is that I allocated s2 on the stack, but I thought strings manage their own content on the heap. Any help here would be appreciated. Thanks, helixed

  • copying a struct with a struct member to another struct

    - by user1839295
    is the following code correct? typedef struct { int x; int y; } OTHERSTRUCT; struct DATATYPE { char a; OTHERSTRUCT b; } // ... // now we reserve two structs struct DATATYPE structA; struct DATATYPE structB; // ... probably fill insome values // now we copy structA to structB structA = structB; Are both structs now completely identical? Even the "struct in the struct"? Thanks!

  • Why is this method executing twice each time I call it?

    - by highone
    I have the following method that is executing twice every time it is called: public static void ChangeToRepository(RepositoryTextBox textBox, int repositoryNumber) { MessageBox.Show("you"); int indexOfLastRepository = (textBox.RepositoryCollection.Count - 1); if (repositoryNumber > indexOfLastRepository) { AddTextRepositoriesThrough(textBox, repositoryNumber, indexOfLastRepository); } textBox.RepositoryCollection[textBox.CurrentRepositoryNumber].CurrentText = textBox.Text; textBox.PreviousRepositoryNumber = textBox.CurrentRepositoryNumber; textBox.CurrentRepositoryNumber = repositoryNumber; textBox.Text = textBox.RepositoryCollection[textBox.CurrentRepositoryNumber].CurrentText; } The first time that the method executes, it executes all of the code except for its last line: textBox.Text = textBox.RepositoryCollection[textBox.CurrentRepositoryNumber].CurrentText; The second time, it executes all of the code. What's up?

  • Setting Curl's Timeout in PHP

    - by Moki
    I'm running a curl request on an eXist database through php. The dataset is very large, and as a result, the database consistently takes a long amount of time to return an XML response. To fix that, we set up a curl request, with what is supposed to be a long timeout. $ch = curl_init(); $headers["Content-Length"] = strlen($postString); $headers["User-Agent"] = "Curl/1.0"; curl_setopt($ch, CURLOPT_URL, $requestUrl); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_USERPWD, 'admin:'); curl_setopt($ch,CURLOPT_TIMEOUT,1000); $response = curl_exec($ch); curl_close($ch); However, the curl request consistently ends before the request is completed (<1000 when requested via a browser). Does anyone know if this is the proper way to set timeouts in curl?

  • Avoiding improper std::string initialization with NULL const char* using g++

    - by pachanga
    A there any g++ options which can detect improper initialization of std::string with NULL const char*? I was in the process of turning some int fields into std::string ones, i.e: struct Foo { int id; Foo() : id(0) {} }; ...turned into: struct Foo { std::string id; Foo() : id(0) {} //oooops! }; I completely overlooked bad 'id' initialization with 0 and g++ gave me no warnings at all. This error was detected in the run time(std::string constructor threw an exception) but I'd really like to detect such stuff in the compile time. Is there any way?

  • Does it take time to deallocate memory?

    - by jm1234567890
    I have a C++ program which, during execution, will allocate about 3-8Gb of memory to store a hash table (I use tr1/unordered_map) and various other data structures. However, at the end of execution, there will be a long pause before returning to shell. For example, at the very end of my main function I have std::cout << "End of execution" << endl; But the execution of my program will go something like $ ./program do stuff... End of execution [long pause of maybe 2 min] $ -- returns to shell Is this expected behavior or am I doing something wrong? I'm guessing that the program is deallocating the memory at the end. But, commercial applications which use large amounts of memory (such as photoshop) do not exhibit this pause when you close the application. Please advise :)

  • Issue with class template partial specialization

    - by DeadMG
    I've been trying to implement a function that needs partial template specializations and fallen back to the static struct technique, and I'm having a number of problems. template<typename T> struct PushImpl<const T&> { typedef T* result_type; typedef const T& argument_type; template<int StackSize> static result_type Push(IStack<StackSize>* sptr, argument_type ref) { // Code if the template is T& } }; template<typename T> struct PushImpl<const T*> { typedef T* result_type; typedef const T* argument_type; template<int StackSize> static result_type Push(IStack<StackSize>* sptr, argument_type ptr) { return PushImpl<const T&>::Push(sptr, *ptr); } }; template<typename T> struct PushImpl { typedef T* result_type; typedef const T& argument_type; template<int StackSize> static result_type Push(IStack<StackSize>* sptr, argument_type ref) { // Code if the template is neither T* nor T& } }; template<typename T> typename PushImpl<T>::result_type Push(typename PushImpl<T>::argument_type ref) { return PushImpl<T>::Push(this, ref); } First: The struct is nested inside another class (the one that offers Push as a member func), but it can't access the template parameter (StackSize), even though my other nested classes all could. I've worked around it, but it would be cleaner if they could just access StackSize like a normal class. Second: The compiler complains that it doesn't use or can't deduce T. Really? Thirdly: The compiler complains that it can't specialize a template in the current scope (class scope). I can't see what the problem is. Have I accidentally invoked some bad syntax?

  • Faster way to iterate through a jaggad array?

    - by George Johnston
    I would like to iterate through an array that covers every pixel on my screen. i.e: for (int y = 598; y > 0; y--) { for (int x = 798; x > 0; x--) { if (grains[x][y]) { spriteBatch.Draw(Grain, new Vector2(x,y), Color.White); } } } ...my texture is a 1x1 pixel image that is drawn to the screen when the array value is true. It runs decent -- but there is definitely lag the more screen I cover. Is there a better way to accomplish what I am trying to achieve?

  • Listview selects mutliple items when clicked

    - by xlph
    I'm trying to make a task manager, and I only have one problem. I have a listview that gets inflated. All the elements in the listview are correct. The problem is that when I select an item, the listview will select another item away. I've heard listviews repopulate the list as it scrolls down to save memory. I think this may be some sort of problem. Here is a picture of the problem. If i had more apps loaded, then it would continue to select multiple at once. Here is the code of my adapter and activity and XML associated public class TaskAdapter extends BaseAdapter{ private Context mContext; private List<TaskInfo> mListAppInfo; private PackageManager mPack; public TaskAdapter(Context c, List<TaskInfo> list, PackageManager pack) { mContext = c; mListAppInfo = list; mPack = pack; } @Override public int getCount() { return mListAppInfo.size(); } @Override public Object getItem(int position) { return mListAppInfo.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(final int position, View convertView, ViewGroup parent) { TaskInfo entry = mListAppInfo.get(position); if (convertView == null) { LayoutInflater inflater = LayoutInflater.from(mContext); //System.out.println("Setting LayoutInflater in TaskAdapter " +mContext +" " +R.layout.taskinfo +" " +R.id.tmbox); convertView = inflater.inflate(R.layout.taskinfo,null); } ImageView ivIcon = (ImageView)convertView.findViewById(R.id.tmImage); ivIcon.setImageDrawable(entry.getIcon()); TextView tvName = (TextView)convertView.findViewById(R.id.tmbox); tvName.setText(entry.getName()); convertView.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { final CheckBox checkBox = (CheckBox)v.findViewById(R.id.tmbox); if(v.isSelected()) { System.out.println("Listview not selected "); //CK.get(arg2).setChecked(false); checkBox.setChecked(false); v.setSelected(false); } else { System.out.println("Listview selected "); //CK.get(arg2).setChecked(true); checkBox.setChecked(true); v.setSelected(true); } } }); return convertView; public class TaskManager extends Activity implements Runnable { private ProgressDialog pd; private TextView ram; private String s; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.taskpage); setTitleColor(Color.YELLOW); Thread thread = new Thread(this); thread.start(); } @Override public void run() { //System.out.println("In Taskmanager Run() Thread"); final PackageManager pm = getPackageManager(); final ListView box = (ListView) findViewById(R.id.cBoxSpace); final List<TaskInfo> CK = populate(box, pm); runOnUiThread(new Runnable() { @Override public void run() { ram.setText(s); box.setAdapter(new TaskAdapter(TaskManager.this, CK, pm)); //System.out.println("In Taskmanager runnable Run()"); endChecked(CK); } }); handler.sendEmptyMessage(0); } Taskinfo.xml <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal" android:gravity="center_horizontal"> <ImageView android:id="@+id/tmImage" android:layout_width="48dp" android:layout_height="48dp" android:scaleType="centerCrop" android:adjustViewBounds="false" android:focusable="false" /> <CheckBox android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/tmbox" android:lines="2"/> </LinearLayout> Taskpage.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <ListView android:id="@+id/cBoxSpace" android:layout_width="wrap_content" android:layout_height="400dp" android:orientation="vertical"/> <TextView android:id="@+id/RAM" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="18sp" /> <Button android:id="@+id/endButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="End Selected Tasks" /> </LinearLayout> Any ideas for what reason mutliple items are selected with a single click would be GREATLY appreciated. I've been messing around with different implementations and listeners and listadapters but to no avail.

  • Which is the best .NET image capture API for me to use?

    - by David
    I have been tasked with integrating image acquisition into a .NET application and I have been looking for an API to use for performing this function. I have come across several "standard" APIs, some have been in existence for a long time, some not so long. I have looked at references to ISIS, TWAIN, WIA, and SANE (said to be mostly *nix). They all appear to be Win32 libraries except for SANE, and I was wondering what the current recommendations are for talking to image acquisition devices (scanners)? Feel free to recommend something else if you feel it is better. I'm looking for open source options. Edit: I put open source, when what I actually meant was free. using WIA or TWAIN is fine since they are free even though they are proprietary interfaces.

    Alright so i am not even sure if this is possible I have a q_00 and q_01 and q_02 which are all in my stored procedure. then on the bottom i have 3 select statements that select a certain catagory for example Sales,Net Sales and INS sales What i want to be able to do is if the user types exec (name of my sp) (sales) (and a year which is the @yearparameter) it will run the sales select statement If they type Exec (name of my SP) netsales (@Yeartoget) it will show the net sales is this possible or do i need multiple stored procedures ALTER PROCEDURE [dbo].[casof] @YearToGet int as ; with q_00 as ( select DIVISION , SDESCR , DYYYY , sum(APRICE) as asofSales , sum(PARTY) as asofPAX , sum(NetAmount) as asofNetSales , sum(InsAmount) as asofInsSales , sum(CancelRevenue) as asofCXSales , sum(OtherAmount) as asofOtherSales , sum(CXVALUE) as asofCXValue from dbo.B101BookingsDetails where Booked <= CONVERT(int,DateAdd(year, @YearToGet - Year(getdate()), DateAdd(day, DateDiff(day, 1, getdate()), 0))) and DYYYY = @YearToGet group by DIVISION, SDESCR, DYYYY ), q_01 as ( select DIVISION , SDESCR , DYYYY , sum(APRICE) as YESales , sum(PARTY) as YEPAX , sum(NetAmount) as YENetSales , sum(InsAmount) as YEInsSales , sum(CancelRevenue) as YECXSales , sum(OtherAmount) as YEOtherSales , sum(CXVALUE) as YECXValue from dbo.B101BookingsDetails where DYYYY=@YearToGet group by DIVISION, SDESCR, DYYYY ), q_02 as ( select DIVISION , SDESCR , DYYYY , sum(APRICE) as CurrentSales , sum(PARTY) as CurrentPAX , sum(NetAmount) as CurrentNetSales , sum(InsAmount) as CurrentInsSales , sum(CancelRevenue) as CurrentCXSales , sum(OtherAmount) as CurrentOtherSales , sum(CXVALUE) as CurrentCXValue from dbo.B101BookingsDetails where Booked <= CONVERT(int,DateAdd(year, (year( getdate() )) - Year(getdate()), DateAdd(day, DateDiff(day, 1, getdate()), 0))) and DYYYY = (year( getdate() )) group by DIVISION, SDESCR, DYYYY ) select a.DIVISION , a.SDESCR , a.DYYYY , asofSales , asofPAX , YESales , YEPAX , CurrentSales , CurrentPAX , asofsales/ ISNULL(NULLIF(yesales,0),1) as percentsales , asofpax/yepax as percentpax ,currentsales/ISNULL(NULLIF((asofsales/ISNULL(NULLIF(yesales,0),1)),0),1) as projectedsales ,currentpax/ISNULL(NULLIF((asofpax/ISNULL(NULLIF(yepax,0),1)),0),1) as projectedpax from q_00 as a join q_01 as b on (b.DIVISION = a.DIVISION and b.SDESCR = a.SDESCR and b.DYYYY = a.DYYYY) join q_02 as c on (b.DIVISION = c.DIVISION and b.SDESCR = c.SDESCR) order by a.DIVISION, a.SDESCR, a.DYYYY ; select a.DIVISION , a.SDESCR , a.DYYYY , asofPAX , asofNetSales , YEPAX , YENetSales , CurrentPAX , CurrentNetSales , asofnetsales/ ISNULL(NULLIF(yenetsales,0),1) as percentnetsales , asofpax/yepax as percentpax ,currentnetsales/ISNULL(NULLIF((asofnetsales/ISNULL(NULLIF(yenetsales,0),1)),0),1) as projectednetsales ,currentpax/ISNULL(NULLIF((asofpax/ISNULL(NULLIF(yepax,0),1)),0),1) as projectedpax from q_00 as a join q_01 as b on (b.DIVISION = a.DIVISION and b.SDESCR = a.SDESCR and b.DYYYY = a.DYYYY) join q_02 as c on (b.DIVISION = c.DIVISION and b.SDESCR = c.SDESCR) order by a.DIVISION, a.SDESCR, a.DYYYY ; select a.DIVISION , a.SDESCR , a.DYYYY , asofPAX , asofInsSales , YEPAX , YEInsSales , CurrentPAX , CurrentInsSales , asofinssales/ ISNULL(NULLIF(yeinssales,0),1) as percentsales , asofpax/yepax as percentpax ,currentinssales/ISNULL(NULLIF((asofinssales/ISNULL(NULLIF(yeinssales,0),1)),0),1) as projectedinssales from q_00 as a join q_01 as b on (b.DIVISION = a.DIVISION and b.SDESCR = a.SDESCR and b.DYYYY = a.DYYYY) join q_02 as c on (b.DIVISION = c.DIVISION and b.SDESCR = c.SDESCR) order by a.DIVISION, a.SDESCR, a.DYYYY ;

  • Count number of queries executed by NHibernate in a unit test

    - by Bittercoder
    In some unit/integration tests of the code we wish to check that correct usage of the second level cache is being employed by our code. Based on the code presented by Ayende here: http://ayende.com/Blog/archive/2006/09/07/MeasuringNHibernatesQueriesPerPage.aspx I wrote a simple class for doing just that: public class QueryCounter : IDisposable { CountToContextItemsAppender _appender; public int QueryCount { get { return _appender.Count; } } public void Dispose() { var logger = (Logger) LogManager.GetLogger("NHibernate.SQL").Logger; logger.RemoveAppender(_appender); } public static QueryCounter Start() { var logger = (Logger) LogManager.GetLogger("NHibernate.SQL").Logger; lock (logger) { foreach (IAppender existingAppender in logger.Appenders) { if (existingAppender is CountToContextItemsAppender) { var countAppender = (CountToContextItemsAppender) existingAppender; countAppender.Reset(); return new QueryCounter {_appender = (CountToContextItemsAppender) existingAppender}; } } var newAppender = new CountToContextItemsAppender(); logger.AddAppender(newAppender); logger.Level = Level.Debug; logger.Additivity = false; return new QueryCounter {_appender = newAppender}; } } public class CountToContextItemsAppender : IAppender { int _count; public int Count { get { return _count; } } public void Close() { } public void DoAppend(LoggingEvent loggingEvent) { if (string.Empty.Equals(loggingEvent.MessageObject)) return; _count++; } public string Name { get; set; } public void Reset() { _count = 0; } } } With intended usage: using (var counter = QueryCounter.Start()) { // ... do something Assert.Equal(1, counter.QueryCount); // check the query count matches our expectations } But it always returns 0 for Query count. No sql statements are being logged. However if I make use of Nhibernate Profiler and invoke this in my test case: NHibernateProfiler.Intialize() Where NHProf uses a similar approach to capture logging output from NHibernate for analysis via log4net etc. then my QueryCounter starts working. It looks like I'm missing something in my code to get log4net configured correctly for logging nhibernate sql ... does anyone have any pointers on what else I need to do to get sql logging output from Nhibernate?

  • is it incorrect to define an hashcode of an object as the sum, multiplication, whatever, of all clas

    - by devoured elysium
    Let's say I have the following class: class ABC { private int myInt = 1; private double myDouble = 2; private String myString = "123"; private SomeRandomClass1 myRandomClass1 = new ... private SomeRandomClass2 myRandomClass2 = new ... //pseudo code public int myHashCode() { return 37 * myInt.hashcode() * myDouble.hashCode() * ... * myRandomClass.hashcode() } } Would this be a correct implementation of hashCode? This is not how I usually do it(I tend to follow Effective Java's guide-lines) but I always have the temptation to just do something like the above code. Thanks

  • The fastest way to do a collection subtraction

    - by Tony
    I have two Sets. Set<B> b is the subset of Set<A> a. they're both very huge Sets. I want to subtract b from a , what's the best practice to do this common operation ? I've written to many codes like this , and I don't think it's efficient. what's your idea ? for(int i = 0 ; i < a.size(); i++) { for (int j=0 ; j < b.size() ;j++) { // do comparison , if found equals ,remove from a break; } } And I want to find an algorithm , not only applies to Sets, also works for Array.

  • Containers of reference_wrappers (comparison operators required?)

    - by kloffy
    If you use stl containers together with reference_wrappers of POD types, the following code works just fine: int i = 3; std::vector< boost::reference_wrapper<int> > is; is.push_back(boost::ref(i)); std::cout << (std::find(is.begin(),is.end(),i)!=is.end()) << std::endl; However, if you use non-POD types such as (contrived example): struct Integer { int value; bool operator==(const Integer& rhs) const { return value==rhs.value; } bool operator!=(const Integer& rhs) const { return !(*this == rhs); } }; It doesn't suffice to declare those comparison operators, instead you have to declare: bool operator==(const boost::reference_wrapper<Integer>& lhs, const Integer& rhs) { return boost::unwrap_ref(lhs)==rhs; } And possibly also: bool operator==(const Integer& lhs, const boost::reference_wrapper<Integer>& rhs) { return lhs==boost::unwrap_ref(rhs); } In order to get the equivalent code to work: Integer j = { 0 }; std::vector< boost::reference_wrapper<Integer> > js; js.push_back(boost::ref(j)); std::cout << (std::find(js.begin(),js.end(),j)!=js.end()) << std::endl; Now, I'm wondering if this is really the way it's meant to be done, since it seems impractical. It just seems there should be a simpler solution, e.g. templates: template<class T> bool operator==(const boost::reference_wrapper<T>& lhs, const T& rhs) { return boost::unwrap_ref(lhs)==rhs; } template<class T> bool operator==(const T& lhs, const boost::reference_wrapper<T>& rhs) { return lhs==boost::unwrap_ref(rhs); } There's probably a good reason why reference_wrapper behaves the way it does (possibly to accomodate non-POD types without comparison operators?). Maybe there already is an elegant solution and I just haven't found it.

  • const return value and template instantiation

    - by Rimo
    From Herb Sutter's GotW #6 Return-by-value should normally be const for non-builtin return types. .... Note: Lakos (pg. 618) argues against returning const value, and notes that it is redundant for builtins anyway (for example, returning "const int"), which he notes may interfere with template instantiation. .... While Sutter seems to disagree on whether to return a const value or non-const value when returning an object of a non-built type by value with Lakos, he generally agrees that returning a const value of a built-in type (e.g const int) is not a good idea. While I understand why that is useless because the return value cannot be modified as it is an rvalue, I cannot find an example of how that might interfere with template instantiation. Please give me an example of how having a const qualifier for a return type might interfere with template instantiation.
