• Why ruby has to_s and inspect?

  - by prosseek

  The p calls inspect, and puts/print calls to_s for representing its object. If I run class Graph def initialize @nodeArray = Array.new @wireArray = Array.new end def to_s # called with print / puts "Graph : #{@nodeArray.size}" end def inspect # called with p "G" end end if __FILE__ == $0 gr = Graph.new p gr print gr puts gr end I get G Graph : 0Graph : 0 Then, why does ruby has two functions do the same thing? What makes the difference between to_s and inspect? If I comment out the to_s or inspect function, I get as follows. ##

• Should I invest time in learning about OR\M or LINQ?

  - by Peter Smith

  I'm a .NET web developer primarily who occasionally writes console applications to mine data, cleanup tasks, etc. Most of what I do winds up involving a database which I currently design via sql server management studio, using stored procedures, and query analyzer. I also create a lot of web services which are consumed via AJAX applications. Do these technologies really help you in speeding up development times? Do you still have to build the database or object code first?

• Create a CBitmap from Resources ID

  - by Smashery

  I need to fill a CImageList with a number of bitmaps which are stored in separate bmp files (rather than as a single bmp with numerous parts). I assume I need to create a CBitmap so I can call the Add method of CImageList. So how might one create a CBitmap object using only MFC Resource IDs?

• [Java] Send cookie with http request problem

  - by nkr1pt

  I'm trying to get a certain cookie in a java client by creating a series of Http requests. It looks like I'm getting a valid cookie from the server but when I'm sending out a request to the fnal url with the seemingly valid cookie I should get some lines of xml in the response but the response is blank because the cookie isw rong or is invalidated because a session has closed or an other problem which I can't figure out. The cookie handed out by the server expires at the end of the session. It seems to me the cookie is valid because when I do the same calls in firefox, a similar cookie with the same name and starting with the 3 first same letters and of the same length is stored in firefox, also expiring at the end of the session. If I then make a request to the final url with only this particular cookie stored in firefox (removed all other cookies), the xml is nicely rendered on the page. Any ideas about what I am doing wrong in this piece of code? One other thing, when I use the value from the very similar cookie generated and strored in firefox in this piece of code, the last request does give xml feedback in the http response! // Validate url = new URL(URL_VALIDATE); conn = (HttpURLConnection) url.openConnection(); conn.setRequestProperty("Cookie", cookie); conn.connect(); String headerName = null; for (int i = 1; (headerName = conn.getHeaderFieldKey(i)) != null; i++) { if (headerName.equals("Set-Cookie")) { if (conn.getHeaderField(i).startsWith("JSESSIONID")) { cookie = conn.getHeaderField(i).substring(0, conn.getHeaderField(i).indexOf(";")).trim(); } } } // Get the XML url = new URL(URL_XML_TOTALS); conn = (HttpURLConnection) url.openConnection(); conn.setRequestProperty("Cookie", cookie); conn.connect(); // Get the response StringBuffer answer = new StringBuffer(); BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream())); String line; while ((line = reader.readLine()) != null) { answer.append(line); } reader.close(); //Output the response System.out.println(answer.toString())

• const object and const constructor

  - by Muhammad alaa

  Is there any way to know if an object is a const object or regular object, for instance consider the following class class String { String(const char* str); }; if user create a const object from String then there is no reason to copy the passed native string and that because he will not make any manipulation on it, the only thing he will do is get string size, string search and other functions that will not change the string.

  I am digging around in a Linux application that supposedly uses DSNs to connet to SQL Server. The connection stopped working and I can't find the credentials that are being used (all I know is the DSN's name). I am familiar with DSNs in Windows, but how are they created and where are they stored in Linux?

• Problem determining how to order F# types due to circular references

  - by James Black

  I have some types that extend a common type, and these are my models. I then have DAO types for each model type for CRUD operations. I now have a need for a function that will allow me to find an id given any model type, so I created a new type for some miscellaneous functions. The problem is that I don't know how to order these types. Currently I have models before dao, but I somehow need DAOMisc before CityDAO and CityDAO before DAOMisc, which isn't possible. The simple approach would be to put this function in each DAO, referring to just the types that can come before it, so, State comes before City as State has a foreign key relationship with City, so the miscellaneous function would be very short. But, this just strikes me as wrong, so I am not certain how to best approach this. Here is my miscellaneous type, where BaseType is a common type for all my models. type DAOMisc = member internal self.FindIdByType item = match(item:BaseType) with | :? StateType as i -> let a = (StateDAO()).Retrieve i a.Head.Id | :? CityType as i -> let a = (CityDAO()).Retrieve i a.Head.Id | _ -> -1 Here is one dao type. CommonDAO actually has the code for the CRUD operations, but that is not important here. type CityDAO() = inherit CommonDAO<CityType>("city", ["name"; "state_id"], (fun(reader) -> [ while reader.Read() do let s = new CityType() s.Id <- reader.GetInt32 0 s.Name <- reader.GetString 1 s.StateName <- reader.GetString 3 ]), list.Empty ) This is my model type: type CityType() = inherit BaseType() let mutable name = "" let mutable stateName = "" member this.Name with get() = name and set restnameval=name <- restnameval member this.StateName with get() = stateName and set stateidval=stateName <- stateidval override this.ToSqlValuesList = [this.Name;] override this.ToFKValuesList = [StateType(Name=this.StateName);] The purpose for this FindIdByType function is that I want to find the id for a foreign key relationship, so I can set the value in my model and then have the CRUD functions do the operations with all the correct information. So, City needs the id for the state name, so I would get the state name, put it into the state type, then call this function to get the id for that state, so my city insert will also include the id for the foreign key. This seems to be the best approach, in a very generic way to handle inserts, which is the current problem I am trying to solve.

• Using the standard Flash AS3 scrollbar class

  - by WebDevHobo

  Flash has a scrollbar class, documented here: http://help.adobe.com/en_US/AS3LCR/Flash_10.0/fl/controls/ScrollBar.html However, besides listing functions and variables, there's no real explanation of how to hook an instance of this class to a textfield. Everything I've tried either ends up in errors or the scrollbar not showing. The documentation lacks a clear way of how you should bind the textfield and the scrollbar toghether, and CS4 isn't providing any help either. Can someone explain, or link to an example of how scrollbars work with textfield?

• Auto-Completion in Unix VI editor

  - by IllustratedInsomnia

  Hey guys, after using graphical IDE's like Visual Studio, I'm used to pressing CTRL+Space to auto-complete a variable or function name. Now, I know such a thing isn't completely possible in VI, but I heard there was a list of commands that could be mapped that allowed automatic completion of variables and functions in the current file opened. Does anyone know what this sequence is? Thanks in advance.
