  • Could someone tell me if my C++ indent style is named? (example given)

    - by Maulrus
    I'm learning C++. For me, my programming style is just what looks the best; it doesn't seem to follow the rules of any one particular style. Here's an example void f(int x){ //no space between close-paren and bracket if (!x){ cout << "x is non-zero\n"; } //closing bracket indented to the same level as the original statement } It's only slightly different for something like a class or a namespace: class myClass {}; //space between class name and bracket, otherwise the same as functions K&R style does uses that kind of bracketing for statements, but my style uses it for everything. I'd like to know if there's a name for it so I can say simply what my indent style is without having to explain using examples like these.

  • Debugging ASP.NET in VS

    - by negligible
    A lot of what I'm doing at the moment is figuring out other peoples code and adding or adapting functions, so currently I am debugging more than I am writing code of my own. I'm still new to this, Junior Developer, and I am always finding new ways to improve what I am doing. For example I recently found This Guide which had some excellent tips, such as overriding the ToString() method in your classes so children are readable from their parents. So I am looking for any other tips or tricks to make my debugging more efficient, as I recognise it as a big part of programming, that you more experienced programmers may have picked up or found. Anything appreciated, I can read websites just fine so no need to explain it yourself if you have a good link!

  • Customer provider Password Reset client.

    - by ProfK
    I'm looking for guidence on writing a custom password reset UI, but it must fit the Provider 'Pattern', or degrade silently to built-in defaults. E.g. my Reset Control must collect extra information, and perform differently to the standard Password Recovery Control. It must close as possible use the standard MembershipProvider interface for standard functions, and only use an extended interface for the non-standard stuff. I'd like some reading on issues such as, what must I ask the Membership Provider for, and what must I do myself. What must I tell the provider (service?) about what I do? Etc.

  • iPhone:(Three20)Unselect (Unhiglight) TTTabItem dynamically?

    - by user187532
    Hello friends, I have four TabBarItem (TTTabItem) in a TabBar (TTTabBar). In one case, i want to remove the TabBarItem selection from any of the four TabBarItems (TTTabItem) . i.e., the complete TabBar will not show any TabBarItems selected. Can i achieve it? I tried the following, [_tabBar1 setSelectedTabItem:nil]; But it is crashing. Could someone guide me to resolve this? I need help urgently. (OR) If we clicked on one TabBarItem(TTTabItem), then again clicking on same TabBarItem(TTTabItem) will not call/execute anything right. Can i make it always clicking on a TabBarItem, should call "(void)tabBar: (UITabBar *)tabBar didSelectItem:(UITabBarItem *)item" (or) any other relevant system functions? I need your helps urgently, could someone guide me for my issue? Thank you.

  • Drawing with GDI+ under IIS

    - by Zac
    I'm running a web application under IIS that we draw graphs with that are sent to the clients. We were previously running under iis6, while migrating to 2008 ( iis7 ) we have encountered some very weird issues with the graphing. I stumbled across the msdn docs for GDI+ stating that "GDI+ functions and classes are not supported for use within a Windows service." I suspect that my issues are probably related to further isolation of services http://msdn.microsoft.com/en-us/library/ms533798%28VS.85%29.aspx My question is how the heck are we supposed to draw graphics? Raw GDI? OpenGL - but doesn't that still require a DC?

  • So I dynamically load a jar at runtime how do I use it?

    - by justinhj
    So question 194698 shows how to load a jar file at runtime and you can load individual named classes and get a Class object. Now my problem is I want to be able to cast those Classes to the types they really are, but I can't because I can't use an import since the whole point is to load it at runtime rather than compile time. It seems like the way to go is to use reflection to discover the functions and field names, but that seems brittle since the API in the jar files could change and the code won't break until it is run. Is there a better way?

  • MSV1_0 Subauthentication Package Registration

    - by BigShot
    Hi; I'm trying to register a simple MSV1_0 subauthentication package for MS Windows Server 2003. I created a dll which implements required functions described in MSDN. I copied my dll to system32 folder. After that, I created a registry key Auth255 (I also tried Auth128) with a REG_SZ value ,which specifies my dll name, to this location; HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\MSV1_0. I expect that it will create a test.txt file for debugging puposes when the dll is called, but it doesn't create the file. How can I make this work?

  • MySql returning multiple rows from stored procedure / function

    - by pistacchio
    Hi, I need to make a stored procedure or function that returns a set of rows. I've noted that in a stored procedure i can SELECT * FROM table with success. If i fetch rows in a loop and SELECT something, something_other FROM table once per loop execution, I only get one single result. What I need to do is looping, doing some calculations and returning a rowset. What's the best way to do this? A temporary table? Stored functions? Any help appreciated.

  • How to give 'Everybody' full rights to a file (programmatically)

    - by egrunin
    I'm modifying an old C++ program to run on Vista. It does not require Admin privileges. I've changed the code to put logfiles in \ProgramData\MyApp\. These logfiles are written with the stdio functions (fopen, fprintf, fclose). Here's the problem: UserA runs the program first, it creates \ProgramData\MyApp\MyLogFile.txt UserB runs the program next, it tries to append to MyLogFile.txt and gets access denied. I tried creating a null SECURITY_DESCRIPTOR and passing that to CreateFile(). That does create a file with "no permissions assigned", but it seems as if the first user to write to the file takes ownership and afterwards all the other non-admin users are out of luck. It's important that all users share the same logfiles, but it's also important that I change as little code as possible.

  • Ruby On Rails CMS Framework

    - by stel
    Hi! I want to create a framework fo rails application. It will be a rails application but packed into gem (like a Radiant CMS). It must work like this: gem install cmsframework and then: cmsframework the_app After that we have a sceleton of rails app without any controllers etc.. - all controllers loaded from cmsframework gem. If I want to rewrite some files (for example public/styles.css) I must simply create it in my app (the_app). If I want new functions in my app I can create a plugin. But the main functionalities must be loaded from cmsframework gem. What is the best way to implement this?

  • Handling the distinction between undefined- and null-parameters in JavaScript

    - by Jakob
    I know very well that null and undefined are distinct in JavaScript. However, I can't seem to decide whether or not use that fact when my own functions are passed one of those as its argument. Or, expressed in a different way, should myFoo(undefined) return the same thing as myFoo(null) or is everything fine if it doesn't? Or, in yet another case, since myBar(1, 2, 3) is the same thing as myBar(1, 2, 3, undefined, undefined), should myBar(1, 2, 3, null, null) return the same thing as myBar(1, 2, 3)? I feel that there's potential for confusion in both cases and that a library should probably follow a convention when handling null/undefined. I'm not really asking for personal opinions (so please express those as comments rather than answers). I'm asking if anyone knows if there is a best practice that one should stick to when it comes to handling this distinction. References to external sources are very welcome!

  • Change a registry value in vb.net

    - by mhofer
    Hello, I have searched a lot to find a solution for my problem, but I can't find any specific solution. I need to change a value which is stored under HKEY_LOCAL_MACHINE\SOFTWARE\APP_NAME. It is not possible to use .NET's registry functions, since they have drastic restrictions. The following snippet should solve my problem: Dim regKey As RegistryKey Dim ver As Decimal regKey = My.Computer.Registry.LocalMachine.OpenSubKey("HKEY_LOCAL_MACHINE\SOFTWARE\APP_NAME", True) regKey.SetValue("IP", "192.168.10.15:18500") regKey.Close() Unfortunately, I get a NullReferenceExeption when I try to set the value. What should I do? I have imported Microsoft.Win32 and RegistryKey doesn't accept any constructor... cheers mike

  • Is there official API for google-maps driving navigation?

    - by Zigfreid
    I've found that on Google support driving navigation on latest Android. http://www.google.com/mobile/navigation/index.html But, I can't find any kinds of API set to provide those kinds of functions. Is there navigation support API? or isn't it released yet? I can't understand why it's not included on Ginger bread version. They said that Nexus S already support Driving navigation. Do you have any information about this issue? Please let me know. Thanks.

  • Porting Windows C++ to Standard (Linux) C++ - WSAGetLastError()

    - by Donal Rafferty
    I am currently porting some Windows mobile C++ code to standard C++. So I am trying to find alternatives for windows specific functions. I have had very little luck in finding a standard C++ function that can help me replace the WSAGetLastError() windows specific function. WSAGetLastError() returns error numbers for errors that occur with sockets in windows. So I was wondering if anyone was aware of a way to replace this function in standard c++? A way to get different error numbers for different outcomes of connecting/dissconection a socket would be sufficent.

  • Sum of distinc rows after a 1-many table join

    - by Lock
    I have 2 tables that I am joining. Table 1 has 1-many relationship with table 2. That is, table 2 can return multiple rows for a single row of table 1. Because of this, the records of table 1 is duplicated for as many rows as are on table 2.. which is expected. Now, I have a sum on one of the columns from table 1, but because of the multiple rows that get returned on the join, the sum is obviously multiplying. Is there a way to get this number back to its original number? I tried dividing by the count of rows from table 2 but this didnt quite give me the expected result. Are there any analytical functions that could do this? I almost want something like "if this row has not yet been counted in the sum, add it to the sum"

  • Java combine parents of two large inheritance chains

    - by Soylent Green
    I have two parent classes in a huge project, let's say ClassA and ClassB. Each class has many subclasses, which in turn have many subclasses, which in turn have many subclasses, etc. My task is to "marry" these two "families" so that both inherit from a SINGLE parent. I need to essentially make ClassA and ClassB one class (parent) to both of their combined subclasses (children). ClassA and ClassB both currently implement Serializable. I am currently trying to make both inheritance chains inherit from ClassA, and then copy all functions and data members from ClassB into ClassA. This is tedious, and I think a terrible solution. What would be the CORRECT way to solve this problem?

  • Expand Expandable Listview in android on button Click

    - by user3146145
    I am implementing expandable list view with its custom adapter. The group element needs to have 2 buttons, first as a parent group element and a button below it. My problem is, I want to expand the list view on click of the button below instead of the group element. Also, The group element onClick needs to call another activity. I can disable the expanding of the expandablelistview by `mainExpListView.setOnGroupClickListener(new OnGroupClickListener() { @Override public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) { return false; }` So my questions: Is there any way to disable the group element and get it to perform other functions (Like navigate to another activity?) How to set an onclick method on them bottom image to expand? Thank you.

  • Bootstrap jquery methods Magento's prototype lib

    - by user1722527
    Wonder if anyone has had this issue. I've integrated Bootstrap nicely into a Magento theme I'm building, all good. That is, until I try using the accordian functions. There seems to be an issue with the code finding the Prototype Libs Methods instead of jQuery's. I've tried the usual fixes, $ - jQuery and no conflict but it only works when I disable the prototype lib - which obviously is not good. Anyone out there come across this and can advise me on a work round? At the moment I'm resigned to using Scriptaculous for the accordian.

  • NSPredicate aggregate function [SIZE] gives 'unsupported function expression' error

    - by jinglesthula
    iOS 4: I have entities in Core Data (using SQLite, which is a requirement) of: Request Response (which has a property personId) Revision Relationships are: Request <-- Revision Request <-- Response Revision <-- Response (e.g. each request may have many responses; each request/response pair may have many revisions) I'm trying to do a predicate to get all Responses with a given personId that have zero Revisions. Using: (personId == %d) && (Request.Revision[SIZE] == 0) in my predicate string gives me a runtime exception "Unsupported function expression Request.Revision[SIZE]" The documentation seems pretty sparse on aggregate functions, only noting that they exist, but with no syntax or examples. Not sure if it's my syntax or if the SIZE function really isn't supported in iOS.

  • Caching result of SELECT statement for reuse in multiple queries

    - by Andrew
    I have a reasonably complex query to extract the Id field of the results I am interested in based on parameters entered by the user. After extracting the relevant Ids I am using the resulting set of Ids several times, in separate queries, to extract the actual output record sets I want (by joining to other tables, using aggregate functions, etc). I would like to avoid running the initial query separately for every set of results I want to return. I imagine my situation is a common pattern so I am interested in what the best approach is. The database is in MS SQL Server and I am using .NET 3.5.

  • Return cell reference as result of if statement with vlookups.

    - by EMJ
    I have two sets of data in excel. One contains a set of data which represents the initial step of a process. The other set of data represents the additional steps which take place after the first step is completed. Each of the data records in the "additional step data" has an id in a column. I need to find the identifying codes of the "additional step data" which correspond with the initial step data records. The problem is that I have to match the data in 4 columns between the two data sets and return the id of the "additional step data". I started by doing a combination of an if and vlookup functions, but I got stuck when I tried to figure out how to get the if statement to reference the id of the matching "additional step data". Basically I am trying to avoid having to search by manually filtering between two sets of data and finding corresponding records. Does anyone have any idea about how to do this?

  • Putting a variable name = value format in Ruby

    - by Calm Storm
    Hi, I would like to add some debugs for my simple ruby functions and I wrote a function as below, def debug(&block) varname = block.call.to_s puts "#{varname} = #{eval(varname,block)}" end debug {:x} #prints x = 5 debug {:y} #prints y = 5 I understand that eval is evil. So I have two questions. Is there any way to write that debug method without using eval? If NO is there a preferred way to do this? Is there any way to pass a list of arguments to this method? I would ideally prefer debug {:x, :y. :anynumOfvariables}. I could not quite figure out how to factor that into the debug method (i.e, to take a list of arguments)

  • What exactly is a memory page fault?

    - by dontWatchMyProfile
    From the docs: Note: Core Data avoids the term unfaulting because it is confusing. There's no “unfaulting” a virtual memory page fault. Page faults are triggered, caused, fired, or encountered. Of course, you can release memory back to the kernel in a variety of ways (using the functions vm_deallocate, munmap, or sbrk). Core Data describes this as “turning an object into a fault”. Is a Fault in Core Data essentially a memory page fault? I have only a slight idea about what a memory page is. I believe it's a kind of "piece of code in memory" which is needed to execute procedures and stuff like that, and as the app is runing, pieces of code are sucked into memory as "pages" and thrown away as they're not needed anymore. Probably 99% wrong ;) Anyone?
