  • When using source control, what files should actually be commited?

    - by SimpleCoder
    I am working on a small project, hosted on Google Code, using SVN for source control. This is my first time using source control, and I'm a bit confused about what I should actually be committing to the repository. My project is very simple: A Class Library project, written in C#. The actual code that I have written is a single file. My question is this: Should I be committing the entire project (including directories like Debug, Release, Properties, etc.) or just my main .cs file? Thanks, After fighting with Subversion for a while (note to self: do not reset repository), it looks like I finally have it working with the directories laid out properly. Thanks again for all your advice.

  • Yet Another Simple Retain Count Question

    - by yar
    [I'm sure this is not odd at all, but I need just a bit of help] I have two retain properties @property (nonatomic, retain) NSArray *listContent; @property (nonatomic, retain) NSArray *filteredListContent; and in the viewDidLoad method I set the second equal to the first self.filteredListContent = self.listContent; and then on every search I do this self.filteredListContent = [listContent filteredArrayUsingPredicate:predicate]; I thought I should do a release right above this assignment -- since the property should cause an extra retain, right? -- but that causes the program to explode the second time I run the search method. The retain counts (without the extra release) are 2 the first time I come into the search method, and 1 each subsequent time (which is what I expected). Some guidance would help, thanks! Is it correct to not release?

  • Delay-Load equivalent in unix based systems

    - by saran
    What is the delay load equivalent in unix based system. I have a code foo.cpp, While compiling with gcc I link it to shared objects(totally three .so files are there.).Each of the .so file for different option. ./foo -v needs libversion.so ./foo -update needs libupdate.so I need the symbol for those libraries should be resolved only at the run time. ./foo -v should not break even if libupdate.so library is not there. It is working in windows using the delay load option(in properties of dll). What is its equivalent in unix systems. Will '-lazy' option does the same in UNIX?. If so,Where to include this option? (in makefile or with linker ld). I am not good in unix. Please help me.. Thanks in advance.

  • ViewState Vs Session ... maintaining object through page lifecycle

    - by Kyle
    Can someone please explain the difference between ViewState and Session? More specifically, I'd like to know the best way to keep an object available (continuously setting members through postbacks) throughout the lifecycle of my page. I currently use Sessions to do this, but I'm not sure if it's the best way. For example: SearchObject searchObject; protected void Page_Load(object sender, EventArgs e) { if(!IsPostBack) { searchObject = new SearchObject(); Session["searchObject"] = searchObject; } else { searchObject = (SearchObject)Session["searchObject"]; } } that allows me to use my searchObject anywhere else on my page but it's kind of cumbersome as I have to reset my session var if I change any properties etc. I'm thinking there must be a better way to do this so that .NET doesn't re-instantiate the object each time the page loads, but also puts it in the global scope of the Page class? Please advise. TIA

  • What is the best way to declare a property?

    - by Simon
    Hi. We declare properties using the @property keyword and synthesize it in the implementation file. My question is, What if I declare a property using the @property keyword and also declare a variable in the interface block with the same name? For example, consider the following code, Interface: @interface myClass : NSObject { NSString *myClass_name; // LINE 1 } @property(nonatomic, retain) NSString *myClass_name; // LINE 2 @end Implementation: @implementation myClass @synthesize myClass_name // LINE 3 @end Declaring myClass_name in LINE 1 will make any problem? Like any reference problem or any unnecessary memory consumption problem?

  • How to load mht from stream/string into a WebBrowser control?

    - by Sameh Serag
    The WebBrowser control loads properly any mht file if I use the Navigate method, but when I use the DocumentText or DocumentStream properties, the source of the mht file is displayed as if I opened the file in notepad. If I write the stream to a temp file then Navigate to it, it works properly, but I don't want to do it this way. This issue seems common, but I didn't find a working solution for it. Some people suggest I should fool IE by implementing IPersistMoniker com interface, ...etc. I have tried with this a little bit, but unfortunately I got the same result. May be I have done something wrong. I still feel their should be a more straightforward solution (other than saving in a temp file first), any idea?

  • Linq to SQl Stored Procedure Problem( it can't figure out the return type)

    - by chobo2
    Hi I have this SP USE [Test] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[UsersInsert](@UpdatedProdData XML) AS INSERT INTO dbo.UserTable(UserId,UserName,LicenseId,Password,PasswordSalt,Email,IsApproved,IsLockedOut,CreateDate, LastLoginDate,LastLockOutDate,FailedPasswordAttempts,RoleId) SELECT @UpdatedProdData.value('(/ArrayOfUsers/Users/UserId)[1]', 'uniqueidentifier'), @UpdatedProdData.value('(/ArrayOfUsers/Users/UserName)[1]', 'varchar(20)'), @UpdatedProdData.value('(/ArrayOfUsers/Users/LicenseId)[1]', 'varchar(50)'), @UpdatedProdData.value('(/ArrayOfUsers/Users/Password)[1]', 'varchar(128)'), @UpdatedProdData.value('(/ArrayOfUsers/Users/PasswordSalt)[1]', 'varchar(128)'), @UpdatedProdData.value('(/ArrayOfUsers/Users/Email)[1]', 'varchar(50)'), @UpdatedProdData.value('(/ArrayOfUsers/Users/IsApproved)[1]', 'bit'), @UpdatedProdData.value('(/ArrayOfUsers/Users/IsLockedOut)[1]', 'bit'), @UpdatedProdData.value('(/ArrayOfUsers/Users/CreateDate)[1]', 'datetime'), @UpdatedProdData.value('(/ArrayOfUsers/Users/LastLoginDate)[1]', 'datetime'), @UpdatedProdData.value('(/ArrayOfUsers/Users/LastLockOutDate)[1]', 'datetime'), @UpdatedProdData.value('(/ArrayOfUsers/Users/FailedPasswordAttempts)[1]', 'int'), @UpdatedProdData.value('(/ArrayOfUsers/Users/RoleId)[1]', 'int') Now this SP creates just fine. It's when I go to VS2010 and try to drag this SP in my method panel of my linq to sql file in design view. It tells me that it can't figure out the return type. I try to go to the properties but it does not have "none" as a choice and I can't type it in. It should be "none" so how do I set it to "none"?

  • Regular Expression to get the size value of a CSS property?

    - by thiesdiggity
    I wrote a regular expression to get the size from a CSS property: /(([+-]?\d*\.?\d+(\s)*(px|em|ex|pt|in|pc|mm|cm)?)|thin|medium|thick)(\s|;|$)/i but for some reason its not working as intended. For example, when I run the following: preg_match_all('/(([+-]?\d*\.?\d+(\s)*(px|em|ex|pt|in|pc|mm|cm)?)|thin|medium|thick)(\s|;|$)/i', "border-bottom:1px solid #99999;", $matches); It outputs: 1px 99999; But I only want the 1px value returned. I understand why its returning the above but can't seem to figure out how to only return the size and not the color value. I tried using the following negative lookbehind but it's not working either: /(((?<!#\d{3}|#\d{6})[+-]?\d*\.?\d+(\s)*(px|em|ex|pt|in|pc|mm|cm)?)|thin|medium|thick)(\s|;|$)/i I want to use preg_match_all for those CSS properties that can have multiple size values (i.e. margin). Anyone have any ideas how to get this regex to return only the size values? Thanks for your help!

  • Why isn't it possible to update an ObservableCollection from a different thread?

    - by MainMa
    In a multi-threaded WPF application, it is not possible to update an ObservableCollection from a thread other than WPF window thread. I know there are workarounds, so my question is not how to avoid the "This type of CollectionView does not support changes to its SourceCollection from a thread different from the Dispatcher thread" exception. My question is, why there is such an exception? Why wasn't it possible to allow collection updates from any thread? Personally, I don't see any reason to block UI update when ObservableCollection is changed from other threads. If two threads (including parallel ones) are accessing the same object, one listening for changes of object properties through events, the other one doing changes, it will always work, at least if locks are used properly. So, what are the reasons?

  • Getting unique items from NSMutableArray

    - by Gidogeek
    Hi Guys, I have a question about Objective-C today involving NSMutableArray. Coming from a .net/c# background I'm having some trouble working with these things. Let's say I have an object called "Song" My song has 3 properties: Title Artist Genre I have a NSMutableArray or NSArray wich holds all my Song objects. How would I go about trying to 'query' my array to get a new array with only (Unique) Artists or Genre's. Where as in .net you would write a simple LINQ query with a DISTINCT clause, how would one solve this in Objective-C ? I'm guessing with predicates but am struggling to find a solution. Thanks in advance.

  • iPhone memory management: a release after setting self.someProperty = nil

    - by ddawber
    I am reading the LazyTableImages code that Apple have released and they do something to this effect (in an NSOperation subclass): - (void)dealloc { [myProperty release]; [myProperty2 release]; } - (void)main { // // Parse operation undertaken here // self.myProperty = nil; self.myProperty2 = nil; } My thinking is that they do this in case dealloc is called before setting properties to nil. Is my thinking correct here? Are the releases unnecessary, as self.myProperty = nil effectively releases myProperty? One thing I have noticed in this code is that they don't release all retained objects in dealloc, only some of them, which is really the cause for my confusion. Cheers

  • How to link to a folder in document library from sharepoint list item?

    - by kyrisu
    Hi, Background: I have an items on the sharepoint list. I also have a corresponding folder in a document library that contains documents about this item. I want to be able to get to this folder straight from the item properties. I have tried to create a lookup column containing folder ID, but that doesn't help cause folder is not a type and it just doesn't work. Other solution would be to create link column but if I will create it staticly - after creating alternative mapping (and getting to the page from the internet for example) it won't work. (so solution posted here won't work for me). I want to create this link from sharepoint workflow. I have a custom action that can return any info about the folder I want (ID, URL etc). Question: How to link from sharepoint list item to a folder in document library?

  • Inheritance policy when designing the base class

    - by Xaqron
    I have a base class and a derived class both in design phase. The base class will remain one but many derived class will inherit from it. So it's very costly to make change to derived classes in the future and I'm looking for the best design to prevent this. In fact derived class only needs a few methods to override (if needed) but it's tempting to reveal more details to it. My question is about the policy which is extensible in future. Can I minimize the inherited methods/properties to derived class and reveal more in the next versions if needed without any change to derived classes ? Or I should reveal anything that maybe used by derived classes in the future and let them to choose if they need them or not ? Thanks

  • Linking error in OMNeT++ using Boost serialization library

    - by astriffe
    I'm very new to OMNeT++ and I'd like to use the serialization-library contained in the boost framework. However, when trying to use it, I get quite many errors such as: Description Resource Path Location Type undefined reference to `boost::archive::archive_exception::~archive_exception()' OmCCN line 36, external location: /home/alexander/UniBE/BT/simulator/boost-compiledLibs /include/boost/serialization/throw_exception.hpp C/C++ Problem . I guess the problem is that I didn't yet link the compiled library in OMNeT. I've had a look at the makefile but any changes there are worthless since it is generated automatically by makemake. Furthermore, trying to access the menu item 'makemake' in project properties OMNeT++ IDE throws an error (The currently displayed page contains invalid values). Can anyone give me a hint concerning what the error could cause or how to link the compiled library correctly? Any hints are very appreciated! cheers alex

  • Is it possible to import specific class from project propreties

    - by Alex
    I have 2 projects. First project need to include second. When I copy sources from second project to first I need to modify manually import path to R.java file. The problem is that I need to use SVN external link connection between this 2 projects, that is mean, one project (the bigger one) will take sources from another through svn and should be able to use it without any modifications. If I would be able to specify R.java file path anywhere in project properties it will resolve my problem by changing manually that path. Need to specify that package name of these 2 projects are different. Another solution to resolve this problem also would be accepted. Thank you.

    Hi, As part of the Android application I am developing in eclipse, I need to combine two packages from different projects into a single project. I tried copying the files in the package of the second project under the src folder of the first folder and copied other files required for second package into the res folder of the first project. But the auto-generated Java files i.e R.java doesn't get updated on copying. I tried right clicking on the project and clicking on Android Tools - Fix Project Properties. But nothing changed. Any pointers on what I am doing wrong much be appreciated.

  • How to generilize view?

    - by MexicanHacker
    Hey guys, I'm in the process of designing a set of views that use the same model in my app, the difference is that some views will differ in Read Only and Modifiable fields. So for example for view A I want to be able to modify A.One but no A.Two properties and for view B I want to have B.One and B.Two as modifiable fields. I was thinking in having a map that will hold this information and iterate both the modifiable and non-modifiable lists in a generic view, but I was thinking that maybe I can get feedback from you guys. What do you think?

  • Entity Framework 4 Hiding Underlying Resolver Tables when model is generated from database

    - by grrrrrrrrrrrrr
    When creating an entity framework model from scratch it is possible to specify a Many to Many relationship in the model. e.g Entity1 * ----- * Entity2 When a database is then generated from this, a resolver table is then created automatically between the two entities, this is hidden in the code model, allowing direct access to each of the entities via properties. e.g. Entity1 ----* ResolverEntity *----- Entity2 My question is, when a model is generated from an existing database, which contains resolver tables, is it possible to create the same effect so the resolver tables do not appear in the generated object model? When I have attempted this, the entity framework appears to create entities in the model for the resolver tables with no obvious way of hiding them in the object model. Thanks.

  • What to do with lookup entities selected from drop down select ? How to send them to the service lay

    - by arrages
    I am developing a spring mvc based application. I have a simple pojo form object, the problem is that many properties will be taked from drop down lists that are populated from lookup entities, so I return the entity ID to the form object. public NewCarRequestForm { private makeId; // this are selected from a drop down. private modelId; } Should I just send this lookup entity ID to the service layer? or should I validated that this ID is correct (Somebody can send any random ID through the request) before and how? Now there is a problem if I want to validated something based on some property of the lookup entity. Do I perform a database lookup of the entity just to perform the validation? thanks.

  • How can I access the iPhone favorite numbers using Objective C?

    - by Cipri
    Hi! I am writing an application using Objective C and I want to access the iPhone favorites numbers (the ones that can be found in the "Phone" application). I've searched among the properties specific to each contact from the Address Book and I even had a look at the Address Book database, but I couldn't identify which property or field from the database indicates which are the favorite numbers. Since "Phone" is an application installed by Apple on the iPhone I was expecting to find such a property in the database. However, I think that it might be possible that this application stores the favorite numbers independently of the Address Book database. Has anyone encountered this problem before and if yes, could you please clarify this matter for me? Thanks a lot! Cipri

  • Visual Studio project build as an executable AND a DLL

    - by East of Nowhere
    In Visual Studio 2008 project properties, Application tab, I can set the Output type to Windows Application, Console Application, or Class Library. I have a project that I want to build as a stand-alone tool (console app) and be available to a couple other tools I'm working on as a class library. The VS GUI only lets me choose one or the other, and building the proj twice all the time is inconvenient. How can I set it up to build both output types in a single build job? Do I write some custom MSBuild .targets file or what?

  • Acceptable to have spaces before dot?

  • C# - Ensuring an assembly is called via a specified assembly

    - by Adam Driscoll
    Is there any built in functionality to determine if an assembly is being called from a particular assembly? I have assembly A which references assembly B. Assembly A exposes PowerShell cmdlets and outputs types that are found within B. Certain methods and properties with in types of exposed by B are of interest to types in assembly A but not of interest to consumers of PowerShell or anyone attempting to load types in B directly and call methods within it. I have looked into InternalsVisibleToAttribute but it would require extensive rework because of the use of interfaces. I was devising a shared key system that would later be obfuscated but that seemed clunky. Is there any way to ensure B is called only by A?

  • How to declare and use the name of a function from a json object?

    - by Sebastian
    Hello, I have a json object collection of geo locations that I build in the server. Each of those objects has two properties: "marker" and "onClick". Marker is for storing a Google Maps marker object and the onClick stores the name of the function to be called when that marker is clicked on the map. When I'm pushing the location objects into an array using javascript in the client side, I create the markers and assign them to each location object within the array. My problem is that when I bind the marker with the onClick property, the function won't be found in the DOM and get an error. Is there a way to declare a property in a json object for using it on an event binding? Hope I could explain it clearly, if not, please let me know. Thanks!
