c++ - stringstream operator>> fails as function, but works as instance? -

I am writing a simple code that will remove a bunch of names, int pairs from a file. I am modifying the existing code which uses just:

  string chrome; Unsigned full size;  

But I want to use a second (similar) input file in which the first two columns are the same, but after the other data (which will be ignored). So I write:

  string chrome; Unsigned full size; String line; (Getline (CIN, line)) {if (stringstream (line)> chrom & gt; size) {// save values}}  

But failing to compile this typical porn study gives Lib Template template:

  error: "operator"> gt; & Gt; "Std :: basic_stringstream"; four; std :: char_traits> four>, std :: communicator> four>> (((constants std :: basic_string & lt; four, std :: char_traits & lt; four & gt; std :: communicator & lt; four & gt; & amp;; ((static std :: basic_string & lt; four; std :: char_traits & lt; four & Gt ;, std :: communicator & lt; four & gt; & gt; *) (& amp; line)), std :: operator | (_S_out, _S_in))>> chrome "isstream: 131 : Note: Candidates are: std :: basic_istream & lt; _CharT, _Traits & gt; & Amp; Std :: basic_istream & lt; _CharT, _Traits & gt; :: Operator & gt; & Gt; (Std :: basic_istream & lt; _CharT, _Traits & gt; & amp; (*) (std :: basic_istream & lt; _CharT, _Traits & gt; & amp;)) [with _CharT = four, _Traits = std :: Char_traits & lt; Char & gt;] [... another dozen lines ...]  

The correct line is not std :: string, but some variations of std :: basic_string, etc. However, to explicitly trigger stringstream functions

  string chrome; Unsigned full size; String line; While (gateline (genome, line)) {stringstream ss (line); If (SS>> Chrome> Size) {// save value} // delete the rest of the line //}  

Why? What is wrong in the first case? Always useful works at cplusplus.com, why is not my code?

Update: Another point of reference: The temporary stringstream works when the first value is extracted is an integer instead of a string:

  unsigned int chrom; // serves as integer ... unsigned full size; String line; While (getline (CIN, line)) {if (stringstream (line)> chrom & gt; size) {// save values}}  

Give over three groups of member tasks and a group of global actions on "extraction operator" (+)

• String Stream (line); - A floating object
• stringstream SS (line); - A common object.

When "chrome" is an integer, operator is more overloaded as arithmetic. Extractor which is a member function is normal object or temporary object is both fine.

When "chrome" is the string, operator istream & amp; Operator & gt; & Gt; (Istream & is, char * str) , it is a global task that should reference the object as a parameter. However, the temporary object has been given, we do not have permission to pass temporary objects from the non-conferencing context in standard C ++. Overload function can not get reference of floating object unless the overload function is istream & amp; Operator & gt; & Gt; (The cost is and is, four * string) Unfortunately, this is not the fact. In case of temporary objects, the function (s) can not be overloaded, and therefore the error: there is no match for the function ...

Error building Visual Studio 2010 Silverlight 4 projects on Windows 7 with XP Mode -

ASP.Net MVC - Showing Model data based on Roles -

I have a view that needs to show and hide details based on the user's role. I have 2 options

1. Use an inline if statement to show and hide in view
2. Create several partial views and use the controller Use and then load the appropriate partial view.

I am a newcomer to MVC so somebody can kindly suggest what is the best way to deal with this problem.

I would probably think differently for each role. I have found that from time to time, thoughts of each role are separated into "mango" content.

ruby - Calling initialize when loading an object serialized with YAML -

Is it possible to force Ruby to call an initial method when using YAML.load_file? For example, I want to call the method to provide value, do not serialize the variable I know that I can factor code into a different method and call YAML.load_file after calling it But I was wondering if there is one more great way to handle this problem.

I do not think you can, because the code you add to is actually specific to the classified class So, you should consider adding convenience to the class. For example, if you want to deserialize the foo class, you can add a class method like:

  class foo def self.from_yaml (yaml) foo = YAML :: load (yaml) # foo Edit the object here foo end end myFoo = Foo.from_yaml ("myFoo.yaml")  

messaging - Why use AMQP/ZeroMQ/RabbitMQ -

Contrary to writing your library.

We are working on a project that is a self-split server pool, if a section becomes very heavy, the manager will divide it and make it a separate machine Keeps in the form. It will also warn all connected clients who affect it to connect to the new server.

I'm curious about using ZeroMQ for inter-server and inter-process communication. My partner would like to roll herself, I am looking at the community to answer this question.

I am a quite novice programmer and have just learned about message lines. As I googled and read, it seems that everyone is using message lines for all things, but why? Does he make it better than writing his library? Why are they so common and why are so many?

What makes them better by writing your own library?

When there is probably nothing to carry out the first version of your app: Your needs are well defined and you will develop a messaging system that meets your needs: Small feature list, small source code etc.

After the first release, very useful later in those devices, when you can actually increase your application and add more features to it Are there. I'll give you some usage cases:

• Your app needs to talk to a big Andian machine (X86, Intel / AMD) with a large Andian Machine (Spark / PowerPC). Your messaging system had some endurance ordering assumptions: go and fix it
• You have created your app, so this is not a binary protocol / messaging system, and now it is very slow because you spend most of your time Pars (number of messages have increased and parsing has become an obstacle): Customize it so that it can transport binary / fixed encoding.

• Start Switch to have had 3 machine within a LAN, any everything from delayed machine. Your client / boss / point-hair-devil-boss appears and tells you that you will install the app on the van which you do not manage - and then you start connection failure, poor latency etc. You need to archive the message and need to resend them later: Go back to the code and plug in this content (and enjoy)

• were sent The message needs to be answered, but not all of them: you expect a spreadsheet as a result instead of sending some parameters and just sending and accepting, go back to the code and plug in this content (and Enjoy.)

• Some messages are important and send required requirements as per reception / backup / backup / persistence. Why do you ask

And many other usage cases that I forgot ...

You can apply it yourself, but do not spend too much time doing this: Will replace it later too.

stored procedures - SQL Best Practices -

Is it good to check that some fields are empty from a table and will return true or false from SP or what values It is good to bring and check in code.

This is usually a better design for a specific business layer, which validates the field for example In a n-tier architecture, the business level will be valid and if the required field disappears then an error will be returned. This means that the data level expects the valid data coming from the business level.

All data levels need to be worried about the recovery of data efficiently and efficiently.

When I use indexpath.row = 0, it's working fine and showing below the header

But when I use indexpath.row = 1, the row 1 will move inside the header section of the table view.

Please help me, I must hide the first row.

[alltweettableView scrollToRowAtIndexPath: [NSIndexPath indexPathForRow: 1 insection: 0] atScrollPosition: Animated UITableViewScrollPositionTop: NO]; Text after "

I'm guessing that you have some transparency / transparency (similar to the contact app) with the default table Headers are using and therefore shows through the bottom of the first line.

Take a look at the documentation for the UITableViewDelegate method, and then you can apply that table to the representative of your table view, send a scene with this non-translucent (or transparent) background, and This should prevent the top row from being displayed.

To get started, I want to return it to a custom shape UILBL directly with a white white background and make sure that it should work (because I have not tested it :) < / P>

  // You probably need to fill the frame size yourself / then try something other than the CGRXeroOr. (UITableView *) tableView viewForHeaderInSection: To start (NSInteger (UIView *) tableView - // example (10,2,320,30), then from there #define x 10 #define Y2 #define width 320 #define height 30 ) Section {UILabel * sectionHeader = [[UILabel alloc] initWithFrame: CGRectMake (X, Y, WIDTH, HEIGHT)]; SectionHeader.text = [NSString stringWithFormat: @ "section% d", section]; SectionHeader.background = [UIColor whiteColor]; Return [section header autoreage]; }  

Assuming that works and looks like progress, you might want to prepare a custom view return that is in the form of the next step.

c# - Question about Object Identity and Object Equality and String class exception -

This is Java and C # questions We all know that object identities (==) test whether the two objects Examine the same place and object equation (equal law) that two separate (non-identical) objects have the same value or not. But in the case of string object object recognition, the object similarity is similar, for example if two bullion expressions are correct in the statement

  string a = "123"; String b = "123"; If (a == b) if (a.Equals (b))  

Why is it ?? What is the rationale behind this design decision? Both Java and C # have used memory-saving techniques because wire is irreversible in these languages.

, They can combine frequently-used stars (such as hard-coded strings as your example are literally) and use several references to a string in memory to save space.

How to get POST data as array with C# -

I am developing an ASP.NET handler with C # that receives data posted by external flash program is. How can I use data as an array? It appears that the HTTP context used in ASP.Net automatically decodes the post data HTML so that it can be removed as a simple string. In this case the separator is a comma (maybe it is always a comma, this has never been worked before).

I need one of two things:

1) For data in your HTML-encoded form, where arrays can be used as a separator for arrays Only customers can represent real arrays instead of input of input (customer input comma will remain encoded at this point). 2) PHP print_r () , a way to emulate the var_dump () function (does not know PHP itself, but I have been told That's the move there) dump the variable to an array.

So any help would be appreciated in advance thanks!

Edit 1: The data being posted can be for a group of examples, postcode and optional additional information. Such as address = testroad% 5F5, second% 5thterthreads% 5F6 and postal code = 12345,56789 and extrainfo =, firstfix . In that example, two addresses (% 5F equals each) were two postal codes, but only in the second address was the space before the comma was empty as extrainfo . Now once again, as English is not my motherhood, the problem was that the prospective customer-written comma is mixed with the actual array-split comma after decoding.

Hosting Silverlight Out of Browser Application in Sharepoint 2007 -

I am trying to host outside of a Silverlight 3 browser application in Sharepoint 2007. My application looks fine; But when I install it out of the browser; And try to run it from the desktop; Only blank screen is displayed and after that nothing happens.

The XAP file is placed in _layout / MyFolder / MyApp.xap (under 12 hives). Am I missing anything?

My Silverlight app uses SharePoint data through its web services; I need to host it within Sharepoint so that they can access the underlying Sharepoint web services.
