  • calling a service layer method to my presentation layer

    - by Josepth Vodary
    Ok I feel really dumb asking this but I seem to be missing something really simple here. I have the following code in a class in my service layer - public Items getItems(String category, float amount, String color, String type) The code reads from a database and returns the results - I plan on placing it in a jframe. Nice and simple. But no matter how I call it from the jframe I get errors in eclipse that the code is wrong - either that their are illegal modifiers or such. So obviously I am calling it completely wrong, so my stupid question is how do you call that method into a jframe? For example - if I try to call it this way: public Items getItems(); I get told that getItems is an illegal parameter. If I call this.. Items getItems(); I am told its undefined

  • Whether to check for null

    - by coffeeaddict
    I know that you should always check incoming params to a method for null. But what if I have this scenario with a try/catch referring to a local variable. Do I really need to check for null below? Because it's gonna catch it anyway if it's null and the next line of code tries to use the refundResponse variable: public string DoRefund(...) { try { ...... string refundTransactionID = string.Empty; ...... RefundTransactionResponseType refundResponse = transaction.DoRefund(...); if (refundResponse != null) refundTransactionID = refundResponse.RefundTransactionID; ..... } catch (Exception ex) { LogError(ex); return ex.ToString(); } }

  • Reading in multiple words for prolog

    - by prolog123456789
    Im running prolog via poplog on unix and was wondering if there was a way to read in multiple words (such as encase it into a string). For instance, read(X) will only allow X to be 1 term. However, if I encase the user input with "", it will return a list of character codes, is this the correct method as I can not find a way to convert it back to a readable string. I would also like to be able to see if the multiworded string contains a set value (for instance, if it contains "i have been") and am unsure of how i will be able to do this as well.

  • using an encrypted web.config file

    - by regy
    My aim is to make the web.config not readable by external users, but my application should be able to access it. Is there any way to do this??? I have tried the following way, but how to set the application to use string instead of web.config??? I want to encrypt my web.config file so that others do not open the file using any editor like notepad. But my application should be able to use the same web.config file. I could encrypt the web.config file and decrypt it inside the application and I saved the entire web.config to a string file. Now I want to use this string variable instead of web.config(now in encrypted form, which cannot be accessed by the application).

  • "An access violation (Segmentation Fault) raised in your program."

    - by Mark
    My C++ program compiles and works up until I call this function from main(): int uword(){fstream infile("numbers.txt"); fstream exfile("wordlist.txt"); string numb[numoflines]; string lines[numoflines]; number = 1; line = 1; for(int i=0;!infile.eof();++i) { getline (infile,number); numb[i] = number; getline (exfile,line); lines[i] = line; } infile.close(); exfile.close(); string yourword; Something here causes it to crash, in the debug it pops up with "An access violation (Segmentation Fault) raised in your program."

  • Creating methods with infinite overloads ? (.NET)

    - by MarceloRamires
    In C# you can do this: foo = string.Format("{0} {1} {2} {3} ...", "aa", "bb", "cc" ...); This method Format() accepts infinite parameters, being the first one how the string should be formatted and the rest are values to be put in the string. Today I've come to a situation where I had to get a set of strings and test them, then I remembered this language functionality, but I had no clue. After a few unsuccessful web searches, I've realised it would be more prudent to just get an array, which didn't make me quite satisfied. Q: How do I make a function that accepts infinite parameters? And how do I use it ?

  • Java: Best approach to have a long list of variables needed all the time without consuming memory?

    - by evilReiko
    I wrote an abstract class to contain all rules of the application because I need them almost everywhere in my application. So most of what it contains is static final variables, something like this: public abstract class appRules { public static final boolean IS_DEV = true; public static final String CLOCK_SHORT_TIME_FORMAT = "something"; public static final String CLOCK_SHORT_DATE_FORMAT = "something else"; public static final String CLOCK_FULL_FORMAT = "other thing"; public static final int USERNAME_MIN = 5; public static final int USERNAME_MAX = 16; // etc. } The class is big and contains LOTS of such variables. My Question: Isn't setting static variables means these variables are floating in memory all the time? Do you suggest insteading of having an abstract class, I have a instantiable class with non-static variables (just public final), so I instantiate the class and use the variables only when I need them. Or is what am I doing is completely wrong approach and you suggest something else?

  • scala: how to rewrite this function using for comprehension

    - by opensas
    I have this piece of code with a couple of nasty nested checks... I'm pretty sure it can be rewritten with a nice for comprehension, but I'm a bit confused about how to mix the pattern matching stuff // first tries to find the token in a header: "authorization: ideas_token=xxxxx" // then tries to find the token in the querystring: "ideas_token=xxxxx" private def applicationTokenFromRequest(request: Request[AnyContent]): Option[String] = { val fromHeaders: Option[String] = request.headers.get("authorization") val tokenRegExp = """^\s*ideas_token\s*=\s*(\w+)\s*$""".r val tokenFromHeader: Option[String] = { if (fromHeaders.isDefined) { val header = fromHeaders.get if (tokenRegExp.pattern.matcher(header).matches) { val tokenRegExp(extracted) = header Some(extracted) } else { None } } else { None } } // try to find it in the queryString tokenFromHeader.orElse { request.queryString.get("ideas_token") } } any hint you can give me?

  • Create tables for a dictionary?

    - by heffaklump
    I'm making a dictionary database in SQLite and need some tips. My SQL is a bit rusty ;) Would you consider this good SQL? It's done with Java JDBC. This is for creating the tables. CREATE TABLE word ( id INTEGER, entry STRING, pos STRING ); CREATE TABLE translation ( word_id INTEGER REFERENCES word(id), entry STRING ); And when filling with data i give each word a number (id) and that words translations get the same number as word_id. What would be the best way of pulling out translations for a specific word?

  • Preserving NULL values in a Double Variable

    - by Sam
    Hi, I'm working on a vb.net application which imports from an Excel spreadsheet. If rdr.HasRows Then Do While rdr.Read() If rdr.GetValue(0).Equals(System.DBNull.Value) Then Return Nothing Else Return rdr.GetValue(0) End If Loop Else I was using string value to store the double values and when preparing the database statement I'd use this code: If (LastDayAverage = Nothing) Then command.Parameters.AddWithValue("@WF_LAST_DAY_TAG", System.DBNull.Value) Else command.Parameters.AddWithValue("@WF_LAST_DAY_TAG", Convert.ToDecimal(LastDayAverage)) End If I now have some data with quite a few decimal places and the data was put into the string variable in scientific notation, so this seems to be the wrong approach. It didn't seem right using the string variable to begin with. If I use a double or decimal type variable, the blank excel values come across as 0.0. How can I preserve the blank values? Thanks

  • Regex: Match opening/closing chars with spaces

    - by Israfel
    I'm trying to complete a regular expression that will pull out matches based on their opening and closing characters, the closest I've gotten is ^(\[\[)[a-zA-Z.-_]+(\]\]) Which will match a string such as "[[word1]]" and bring me back all the matches if there is more than one, The problem is I want it to pick up matchs where there may be a space in so for example "[[word1 word2]]", now this will work if I add a space into my pattern above however this pops up a problem that it will only get one match for my entire string so for example if I have a string "Hi [[Title]] [[Name]] [[surname]], How are you" then the match will be "[[Title]] [[Name]] [[surname]]" rather than 3 matches "[[Title]]", "[[Name]]", "[[surname]]". I'm sure I'm just a char or two away in the Regex but I'm stuck, How can I make it return the 3 matches. Thanks

  • Best way to integrate searching with pagination

    - by Vijay Choudhary
    I have a web application build on cakephp 2.x. I have integrated pagination on my data. Now i want to implement searching on that data also, and pagination should work according to search result. Now my question is: Should i use a form to post my search string. If so, then which method should i use, GET or POST. OR, should i use javascript window.location method, and append the search string to it. If we use this method then search string can append more than once to url. Or any other best way to implement this. Can anybody give the best solution for this as it is a common task for each application to have.

  • how to integrate my users database table with the aspnet_users table that comes with asp.net members

    - by ooo
    i have a database that already has a users table COLUMNS: userID - int loginName - string First - string Last - string i just installed the asp.net membership table. Right now all of my tables are joined into my users table foreign keyed into the "userId" field How do i integrate asp.net_users table into my schema? here are the ideas i thought of: Add a membership_id field to my users table and on new inserts, include that new field in my users table. This seems like the cleanest way as i dont need to break any existing relationships. break all existing relationship and move all of the fields in my user table into the asp.net_users table. This seems like a pain but ultimately will lead to the most simple, normalized solution any thoughts?

  • Flex - Use Variables for Object Attribute Names

    - by Immanuel
    How do you use variables to access Object attributes? Suppose I have an Object declared as follows, var obj:Object = new Object; obj.Name = "MyName"; obj.Age = "10"; How would i do something like this, var fieldName:String = "Name"; var fieldAge:String = "Age"; var Name_Age:String = obj.fieldName + " ," + obj.fieldAge; The code above treats 'fieldName' and 'fieldAge' as attribute name itself. I want to treat the same as a variable, and map the value associated with the variable as the Object attribute name.
