  • Is there an easy way to make `boost::ptr_vector` more debugger friendly in Visual Studio?

    - by Billy ONeal
    I'm considering using boost::ptr_container as a result of the responses from this question. My biggest problem with the library is that I cannot view the contents of the collection in the debugger, because the MSVC debugger doesn't recognize it, and therefore I cannot see the contents of the containers. (All the data gets stored as void * internally) I've heard MSVC has a feature called "debugger visualizers" which would allow the user to make the debugger smarter about these kinds of things, but I've never written anything like this, and I'm not hugely firmiliar with such things. For example, compare the behavior of boost::shared_ptr with MSVC's own std::tr1::shared_ptr. In the debugger (i.e. in the Watch window), the boost version shows up as a big mess of internal variables used for implementing the shared pointer, but the MSVC version shows up as a plain pointer to the object (and the shared_ptr's innards are hidden). How can I get started either using or implementing such a thing?

  • Is it possible to read infinity or NaN values using input streams?

    - by Drise
    I have some input to be read by a input filestream (for example): -365.269511 -0.356123 -Inf 0.000000 When I use std::ifstream mystream; to read from the file to some double d1 = -1, d2 = -1, d3 = -1, d4 = -1; (assume mystream has already been opened and the file is valid), mystream >> d1 >> d2 >> d3 >> d4; mystream is in the fail state. I would expect std::cout << d1 << " " << d2 << " " << d3 << " " << d4 << std::endl; to output -365.269511 -0.356123 -1 -1. I would want it to output -365.269511 -0.356123 -Inf 0 instead. This set of data was output using C++ streams. Why can't I do the reverse process (read in my output)? How can I get the functionality I seek? From MooingDuck: #include <iostream> #include <limits> using namespace std; int main() { double myd = std::numeric_limits<double>::infinity(); cout << myd << '\n'; cin >> myd; cout << cin.good() << ":" << myd << endl; return 0; } Input: inf Output: inf 0:inf See also: http://ideone.com/jVvei Also related to this problem is NaN parsing, even though I do not give examples for it.

  • Transaction issue in java with hibernate - latest entries not pulled from database

    - by Gearóid
    Hi, I'm having what seems to be a transactional issue in my application. I'm using Java 1.6 and Hibernate 3.2.5. My application runs a monthly process where it creates billing entries for a every user in the database based on their monthly activity. These billing entries are then used to create Monthly Bill object. The process is: Get users who have activity in the past month Create the relevant billing entries for each user Get the set of billing entries that we've just created Create a Monthly Bill based on these entries Everything works fine until Step 3 above. The Billing Entries are correctly created (I can see them in the database if I add a breakpoint after the Billing Entry creation method), but they are not pulled out of the database. As a result, an incorrect Monthly Bill is generated. If I run the code again (without clearing out the database), new Billing Entries are created and Step 3 pulls out the entries created in the first run (but not the second run). This, to me, is very confusing. My code looks like the following: for (User user : usersWithActivities) { createBillingEntriesForUser(user.getId()); userBillingEntries = getLastMonthsBillingEntriesForUser(user.getId()); createXMLBillForUser(user.getId(), userBillingEntries); } The methods called look like the following: @Transactional public void createBillingEntriesForUser(Long id) { UserManager userManager = ManagerFactory.getUserManager(); User user = userManager.getUser(id); List<AccountEvent> events = getLastMonthsAccountEventsForUser(id); BillingEntry entry = new BillingEntry(); if (null != events) { for (AccountEvent event : events) { if (event.getEventType().equals(EventType.ENABLE)) { Calendar cal = Calendar.getInstance(); Date eventDate = event.getTimestamp(); cal.setTime(eventDate); double startDate = cal.get(Calendar.DATE); double numOfDaysInMonth = cal.getActualMaximum(Calendar.DAY_OF_MONTH); double numberOfDaysInUse = numOfDaysInMonth - startDate; double fractionToCharge = numberOfDaysInUse/numOfDaysInMonth; BigDecimal amount = BigDecimal.valueOf(fractionToCharge * Prices.MONTHLY_COST); amount.scale(); entry.setAmount(amount); entry.setUser(user); entry.setTimestamp(eventDate); userManager.saveOrUpdate(entry); } } } } @Transactional public Collection<BillingEntry> getLastMonthsBillingEntriesForUser(Long id) { if (log.isDebugEnabled()) log.debug("Getting all the billing entries for last month for user with ID " + id); //String queryString = "select billingEntry from BillingEntry as billingEntry where billingEntry>=:firstOfLastMonth and billingEntry.timestamp<:firstOfCurrentMonth and billingEntry.user=:user"; String queryString = "select be from BillingEntry as be join be.user as user where user.id=:id and be.timestamp>=:firstOfLastMonth and be.timestamp<:firstOfCurrentMonth"; //This parameter will be the start of the last month ie. start of billing cycle SearchParameter firstOfLastMonth = new SearchParameter(); firstOfLastMonth.setTemporalType(TemporalType.DATE); //this parameter holds the start of the CURRENT month - ie. end of billing cycle SearchParameter firstOfCurrentMonth = new SearchParameter(); firstOfCurrentMonth.setTemporalType(TemporalType.DATE); Query query = super.entityManager.createQuery(queryString); query.setParameter("firstOfCurrentMonth", getFirstOfCurrentMonth()); query.setParameter("firstOfLastMonth", getFirstOfLastMonth()); query.setParameter("id", id); List<BillingEntry> entries = query.getResultList(); return entries; } public MonthlyBill createXMLBillForUser(Long id, Collection<BillingEntry> billingEntries) { BillingHistoryManager manager = ManagerFactory.getBillingHistoryManager(); UserManager userManager = ManagerFactory.getUserManager(); MonthlyBill mb = new MonthlyBill(); User user = userManager.getUser(id); mb.setUser(user); mb.setTimestamp(new Date()); Set<BillingEntry> entries = new HashSet<BillingEntry>(); entries.addAll(billingEntries); String xml = createXmlForMonthlyBill(user, entries); mb.setXmlBill(xml); mb.setBillingEntries(entries); MonthlyBill bill = (MonthlyBill) manager.saveOrUpdate(mb); return bill; } Help with this issue would be greatly appreciated as its been wracking my brain for weeks now! Thanks in advance, Gearoid.

  • GWT AbstractColumnDefinition (Need to add style to certain Columns)

    - by Mario
    I have a column Definition for each colume that extends AbstractColumnDefinition these columns are put in a DefaultTableDefinition. example: NAME | SIZE | RES | DELETE | this style (AT THE END OF THE PAGE ) is added to the column names if you notice all of them are with a cursor pointer , meaning a hand shows up when i hover above each one. my question is would I be able to remove the coursor for delete or in general for a certain column and keeping it for another one .. i tried to do that with each column Definition but there is no such thing as remove or addstyle even to like put my own style. THANK YOU .gwt-ScrollTable .headerTable td { border-bottom:1px solid black; border-left:1px solid #CCCCCC; border-right:1px solid #CCCCCC; cursor:pointer; vertical-align:bottom; }

  • Android: who can help me with setting up this google maps class please??

    - by Capsud
    Hi, Firstly this has turned out to be quite a long post so please bear with me as its not too difficult but you may need to clarify something with me if i haven't explained it correctly. So with some help the other day from guys on this forum, i managed to partially set up my 'mapClass' class, but i'm having trouble with it and its not running correctly so i would like some help if possible. I will post the code below so you can see. What Ive got is a 'Dundrum' class which sets up the listView for an array of items. Then ive got a 'dundrumSelector' class which I use to set up the setOnClickListener() methods on the listItems and link them to their correct views. DundrumSelector class.. public static final int BUTTON1 = R.id.anandaAddressButton; public static final int BUTTON2 = R.id.bramblesCafeAddressButton; public static final int BUTTON3 = R.id.brannigansAddressButton; public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); int position = getIntent().getExtras().getInt("position"); if(position == 0){ setContentView(R.layout.ananda); }; if(position == 1){ setContentView(R.layout.bramblescafe); }; if(position == 2){ setContentView(R.layout.brannigans); Button anandabutton = (Button) findViewById(R.id.anandaAddressButton); anandabutton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Intent myIntent = new Intent(view.getContext(),MapClass.class); myIntent.putExtra("button", BUTTON1); startActivityForResult(myIntent,0); } }); Button bramblesbutton = (Button) findViewById(R.id.bramblesCafeAddressButton); bramblesbutton.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { Intent myIntent = new Intent(view.getContext(),MapClass.class); myIntent.putExtra("button", BUTTON2); startActivityForResult(myIntent, 0); } }); etc etc.... Then what i did was set up static ints to represent the buttons which you can see at the top of this class, the reason for this is because in my mapClass activity I just want to have one method, because the only thing that is varying is the coordinates to each location. ie. i dont want to have 100+ map classes essentially doing the same thing other than different coordinates into the method. So my map class is as follows... case DundrumSelector.BUTTON1: handleCoordinates("53.288719","-6.241179"); break; case DundrumSelector.BUTTON2: handleCoordinates("53.288719","-6.241179"); break; case DundrumSelector.BUTTON3: handleCoordinates("53.288719","-6.241179"); break; } } private void handleCoordinates(String l, String b){ mapView = (MapView) findViewById(R.id.mapView); LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom); View zoomView = mapView.getZoomControls(); zoomLayout.addView(zoomView, new LinearLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); mapView.displayZoomControls(true); mc = mapView.getController(); String coordinates[] = {l, b}; double lat = Double.parseDouble(coordinates[0]); double lng = Double.parseDouble(coordinates[1]); p = new GeoPoint( (int) (lat*1E6), (int) (lng*1E6)); mc.animateTo(p); mc.setZoom(17); mapView.invalidate(); } Now this is where my problem is. The onClick() events don't even work from the listView to get into the correct views. I have to comment out the methods in 'DundrumSelector' before I can get into their views. And this is what I dont understand, firstly why wont the onClick() events work, because its not even on that next view where the map is. I know this is a very long post and it might be quite confusing so let me know if you want any clarification.. Just to recap, what i'm trying to do is just have one class that sets up the map coordinates, like what i'm trying to do in my 'mapClass'. Please can someone help or suggest another way of doing this! Thanks alot everyone for reading this.

    - by nuttynibbles
    hi, i have created a cab file using visual studio smart device cab project. i've managed to generate a cab file and install onto a mobile phone successfully. for my installation, it will also insert into registry. however, for this it is not working. the registry value is suppose to be like this including the double quote: "\Program Files\app\file.exe" "%1" i read that to include '%', i have to insert extra % which will be like this: "\Program Files\app\file.exe" "%%1" but this is still not getting insert into the registry. however, if i remove the double quotes which looks like this, it works: \Program Files\app\file.exe %%1 Thanks.

  • is my function correct?

    - by sbsp
    This is part of an assignment so please dont post solutions, just point me in the right direction if possible? I am passing a pointer to a char array to my method, as well as a value for the actual height of the char array. I am looping through to see if all values are 0, if they are then return 0, esle return one The method is used as a test to see if i should free memory or not and set the pointer to null if it is full of 0's. The issue i am having is that the programme should have "some unfree" memory at the end, so i have no idea whether or not its doing it correctly - and gdb i struggle with immensley. Thanks for reading int shouldBeNull(char *charPointer, int sizeOfCharArray) { int isIn = 0; int i = 0; while(i < sizeOfCharArray){ if(*charPointer != '0'){ isIn = 1; break; } i++; charPointer++; } return isIn; }

  • How can I write a power function myself?

    - by Koning WWWWWWWWWWWWWWWWWWWWWWW
    Since I was 12, I was always wondering how I can make a function which calculates the power (e.g. 23) myself. In most languages these are included in the standard library, mostly as pow(double x, double y), but how can I write it myself? I was thinking about for loops, but it think my brain got in a loop (when I wanted to do a power with a non-integer exponent, like 54.5 or negatives 2-21) and I went crazy ;) So, how can I write a function which calculates the power of a real number? Thanks

  • Process for linking static ObjC libraries in XCode

    - by madmik3
    I'm trying to link to a static library and I keep getting linker errors. I've found a few sites that post examples but I have not been able to see what I am doing wrong. First I create a project that will link to my lib add existing files find my .xcodeproj file select "Copy items into destination groups folder"... Select my host project as Add To Targets. Then I add a direct dependency to my host app expand targets double click MyHost.app click + under direct dependencies select my lib Then I set build flags double click MyHost application icon in Groups and Files. click the build tab then I set the OtherLinerFlag to -ObjC then I set Header Search Paths to my header file location for my static library. I pass the compile stage but any classes in my static lib cause linker error: literal-pointer@_OBJC@_cls_refs@SomeClass in MyHost.o thanks!

  • What division operator symbol would you pick?

    - by Mackenzie
    I am currently designing and implementing a small programming language as an extra-credit project in a class I'm taking. My problem is that the language has three numeric types: Long, Double, and Fraction. Fractions can be written in the language as proper or improper fractions (e.g. "2 1/3" or "1/2"). This fact leads to problems such as "2/3.5" (Long/Double) and "2/3"(Long/Long) not being handled correctly by the lexer.The best solution that I see is to change the division operator. So far, I think "\" is the best solution since "//" starts comments. Would you pick "\", if you were designing the language? Would you pick something else? If so, what? Note: changing the way fractions are written is not possible. Thanks in advance for your help,

  • How to improve workflow for creating a Lua-based Wireshark dissector

    - by piyo
    I've finally created a Dissector for my UDP protocol in Lua for Wireshark, but the work flow is just horrendous. It consists of editing my custom Lua file in my editor, then double-clicking my example capture file to launch Wireshark to see the changes. If there was an error, Wireshark informs me via dialogs or a red line in the Tree analysis sub-pane. I then re-edit my custom Lua file and then close that Wireshark instance, then double-click my example capture file again. It's like compiling a C file and only seeing one compiler error at a time. Is there a better (faster) way of looking at my changes, without having to restart Wireshark all the time? At the time, I was using Wireshark 1.2.9 for Windows with Lua enabled.

  • user defined Copy ctor, and copy-ctors further down the chain - compiler bug ? programmers brainbug

    - by J.Colmsee
    Hi. i have a little problem, and I am not sure if it's a compiler bug, or stupidity on my side. I have this struct : struct BulletFXData { int time_next_fx_counter; int next_fx_steps; Particle particles[2];//this is the interesting one ParticleManager::ParticleId particle_id[2]; }; The member "Particle particles[2]" has a self-made kind of smart-ptr in it (resource-counted texture-class). this smart-pointer has a default constructor, that initializes to the ptr to 0 (but that is not important) I also have another struct, containing the BulletFXData struct : struct BulletFX { BulletFXData data; BulletFXRenderFunPtr render_fun_ptr; BulletFXUpdateFunPtr update_fun_ptr; BulletFXExplosionFunPtr explode_fun_ptr; BulletFXLifetimeOverFunPtr lifetime_over_fun_ptr; BulletFX( BulletFXData data, BulletFXRenderFunPtr render_fun_ptr, BulletFXUpdateFunPtr update_fun_ptr, BulletFXExplosionFunPtr explode_fun_ptr, BulletFXLifetimeOverFunPtr lifetime_over_fun_ptr) :data(data), render_fun_ptr(render_fun_ptr), update_fun_ptr(update_fun_ptr), explode_fun_ptr(explode_fun_ptr), lifetime_over_fun_ptr(lifetime_over_fun_ptr) { } /* //USER DEFINED copy-ctor. if it's defined things go crazy BulletFX(const BulletFX& rhs) :data(data),//this line of code seems to do a plain memory-copy without calling the right ctors render_fun_ptr(render_fun_ptr), update_fun_ptr(update_fun_ptr), explode_fun_ptr(explode_fun_ptr), lifetime_over_fun_ptr(lifetime_over_fun_ptr) { } */ }; If i use the user-defined copy-ctor my smart-pointer class goes crazy, and it seems that calling the CopyCtor / assignment operator aren't called as they should. So - does this all make sense ? it seems as if my own copy-ctor of struct BulletFX should do exactly what the compiler-generated would, but it seems to forget to call the right constructors down the chain. compiler bug ? me being stupid ? Sorry about the big code, some small example could have illustrated too. but often you guys ask for the real code, so well - here it is :D EDIT : more info : typedef ParticleId unsigned int; Particle has no user defined copyctor, but has a member of type : Particle { .... Resource<Texture> tex_res; ... } Resource is a smart-pointer class, and has all ctor's defined (also asignment operator) and it seems that Resource is copied bitwise. EDIT : henrik solved it... data(data) is stupid of course ! it should of course be rhs.data !!! sorry for huge amount of code, with a very little bug in it !!! (Guess you shouldn't code at 1 in the morning :D )

  • Why C++ virtual function defined in header may not be compiled and linked in vtable?

    - by 0xDEAD BEEF
    Situation is following. I have shared library, which contains class definition - QueueClass : IClassInterface { virtual void LOL() { do some magic} } My shared library initialize class member QueueClass *globalMember = new QueueClass(); My share library export C function which returns pointer to globalMember - void * getGlobalMember(void) { return globalMember;} My application uses globalMember like this ((IClassInterface*)getGlobalMember())->LOL(); Now the very uber stuff - if i do not reference LOL from shared library, then LOL is not linked in and calling it from application raises exception. Reason - VTABLE contains nul in place of pointer to LOL() function. When i move LOL() definition from .h file to .cpp, suddenly it appears in VTABLE and everything works just great. What explains this behavior?! (gcc compiler + ARM architecture_)

  • Basic Custom String Class for C++

    - by wdow88
    Hey all, I'm working on building my own string class with very basic functionality. I am having difficulty understand what is going on with the basic class that I have define, and believe there is some sort of error dealing with the scope occurring. When I try to view the objects I created, all the fields are described as (obviously bad pointer). Also, if I make the data fields public or build an accessor method, the program crashes. For some reason the pointer for the object is 0xccccccccc which points to no where. How can a I fix this? Any help/comments are much appreciated. //This is a custom string class, so far the only functions are //constructing and appending #include<iostream> using namespace std; class MyString1 { public: MyString1() { //no arg constructor char *string; string = new char[0]; string[0] ='\0'; std::cout << string; size = 1; } //constructor receives pointer to character array MyString1(char* chars) { int index = 0; //Determine the length of the array while (chars[index] != NULL) index++; //Allocate dynamic memory on the heap char *string; string = new char[index+1]; //Copy the contents of the array pointed by chars into string, the char array of the object for (int ii = 0; ii < index; ii++) string[ii] = chars[ii]; string[index+1] = '\0'; size = index+1; } MyString1 append(MyString1 s) { //determine new size of the appended array and allocate memory int newsize = s.size + size; MyString1 MyString2; char *newstring; newstring = new char[newsize+1]; int index = 0; //load the first string into the array while (string[index] != NULL) { newstring[index] = string[index]; index++; } //load the second string while (s.string[index] != NULL) { newstring[index] = s.string[index]; index++; } //null terminate newstring[newsize+1] = '\0'; delete string; //generate the object for return MyString2.string=newstring; MyString2.size=newsize; return MyString2; } private: char *string; int size; }; int main() { MyString1 string1; MyString1 string2("Hello There"); MyString1 string3("Buddy"); string2.append(string3); return 0; }

  • C# Enum Flags Comparison

    - by destructo_gold
    Given the following flags, [Flags] public enum Operations { add = 1, subtract = 2, multiply = 4, divide = 8, eval = 16, } How could I implement an IF condition to perform each operation? In my attempt, the first condition is true for add, eval, which is correct. However the first condition is also true for subtract, eval, which is incorrect. public double Evaluate(double input) { if ((operation & (Operations.add & Operations.eval)) == (Operations.add & Operations.eval)) currentResult += input; else if ((operation & (Operations.subtract & Operations.eval)) == (Operations.subtract & Operations.eval)) currentResult -= input; else currentResult = input; operation = null; return currentResult; } I cannot see what the problem is.

  • Intercept windows open file

    - by HyLian
    Hello, I'm trying to make a small program that could intercept the open process of a file. The purpose is when an user double-click on a file in a given folder, windows would inform to the software, then it process that petition and return windows the data of the file. Maybe there would be another solution like monitoring Open messages and force Windows to wait while the program prepare the contents of the file. One application of this concept, could be to manage desencryption of a file in a transparent way to the user. In this context, the encrypted file would be on the disk and when the user open it ( with double-click on it or with some application such as notepad ), the background process would intercept that open event, desencrypt the file and give the contents of that file to the asking application. It's a little bit strange concept, it could be like "Man In The Middle" network concept, but with files instead of network packets. Thanks for reading.

  • Viewing array of pointers to structures in Visual Studio in the debugger

    - by Fozi
    I'm having a problem displaying the contents of a pointer array with its contents in the debugger. If I just add the pointer to the watch only the fist entry is visible. But if I add the length to it the debugger assumes that I have something like array[length][length]. Picture The first entry is the broken one, looks the same with ,2 or with any ,2 x. The second one is what I would like to see, but for more entries. Edit: The two entries displayed as [x][1] are invalid. I'm using VS 2005 but I think I had this problem on 2008 as well. Is this a bug or am I doing something wrong?

  • What is the safest way to pass strings around in C?

    - by chucknelson
    I have a program in C using Solaris with VERY ancient compatibility it seems. Many examples, even here on SO, don't work, as well as lots of code I've written on Mac OS X. So when using very strict C, what is the safest way to pass strings? I'm currently using char pointers all over the place, due to what I thought was simplicity. So I have functions that return char*, I'm passing char* to them, etc. I'm already seeing strange behavior, like a char* I passed having its value right when I enter a function, and then the value being mysteriously gone OR corrupted/overwritten after something simple like one printf() or an malloc to some other pointer. I was thinking maybe declaring a local char[] inside each function, using strcpy() immediately, and then eventually returning a pointer where char *returnval = strdup(localchar[]); This seems...sloppy. Can anyone point me in the right direction on a simple requirement?

  • How to use > in an xargs command?

    - by jesse
    I want to find a bash command that will let me grep every file in a directory and write the output of that grep to a separate file. My guess would have been to do something like this ls -1 | xargs -I{} "grep ABC '{}' > '{}'.out" but, as far as I know, xargs doesn't like the double-quotes. If I remove the double-quotes, however, then the command redirects the output of the entire command to a single file called '{}'.out instead of to a series of individual files. Does anyone know of a way to do this using xargs? I just used this grep scenario as an example to illustrate my problem with xargs so any solutions that don't use xargs aren't as applicable for me.

  • Is ORM (Linq, Hibernate...) really that useful?

    - by Peter
    I have been playing with some LINQ ORM (LINQ directly to SQL) and I have to admit I like its expressive powers . For small utility-like apps, It also works quite fast: dropping a SQL server on some surface and you're set to linq away. For larger apps however, the DAL never was that big of an issue to me to setup, nor maintain, and more often than not, once it was set, all the programming was not happening there anyway... My, honest - I am an ORM newbie - question : what is the big advantage of ORM over writing a decent DAL by hand? (seems like a double, couldn't find it though) UPDATE : OK its a double :-) I found it myself eventually : ORM vs Handcoded Data Access Layer
