• Can you use zero-width matching regex in String split?

  - by polygenelubricants

  System.out.println( Arrays.deepToString( "abc<def>ghi".split("(?:<)|(?:>)") ) ); This prints [abc, def, ghi], as if I had split on "<|>". I want it to print [abc, <def>, ghi]. Is there a way to work some regex magic to accomplish what I want here? Perhaps a simpler example: System.out.println( Arrays.deepToString( "Hello! Oh my!! Good bye!!".split("(?:!+)") ) ); This prints [Hello, Oh my, Good bye]. I want it to print [Hello!, Oh my!!, Good bye!!]. `.

• Is it necessarily bad style to ignore the return value of a method

  - by Jono

  Let's say I have a C# method public void CheckXYZ(int xyz) { // do some operation with side effects } Elsewhere in the same class is another method public int GetCheckedXYZ(int xyz) { int abc; // functionally equivalent operation to CheckXYZ, // with additional side effect of assigning a value to abc return abc; // this value is calculated during the check above } Is it necessarily bad style to refactor this by removing the CheckXYZ method, and replacing all existing CheckXYZ() calls with GetCheckedXYZ(), ignoring the return value? The returned type isn't IDisposable in this case. Does it come down to discretion?

• url rewriting + Asp.Net Login Form = Death

  - by xor88

  Hi, on our site we do url rewriting to generate massive amounts of database generated pages. on every page, there is a Login control for users. like this: Internal aspx page: /DB.aspx?id=123 User visible url: /ABC/123.aspx, /ABC/456.aspx ... (url rewritten) unfortunately, the tag on each page has an action attribute of "DB.aspx?id=123". when the user clicks the button the browser is posting to /ABC/DB.aspx?id=123 which of course does not exist. solutions i tried: 1. change the action attribute by subclassing HtmlForm. this destroys the all other forms on the site. 2. remove the action attribute (so that the browser is always posting to the same url). this works on the rewritten pages but on "/" (the default.aspx in the root dir) i get a message that the verb post is not allowed on "/" (iis 6 and i have no control over mappings) anybody?

• <jaxrs:client> not getting autowired

  I am trying to build a restful client using jaxrs:client as defined in http://svn.apache.org/repos/asf/cxf/trunk/systests/jaxrs/src/test/resources/jaxrs_soap_rest/WEB-INF/beans.xml In my test class I am getting org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.abc.service.ExportServiceTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.bankbazaar.service.ExportService com.abc.service.ExportServiceTest.exportClient; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.abc.service.ExportService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

• implement string class with custom behavior

  - by truman

  In one of our class sir said that template allows one to customize behavior of class, and then he gave example of string class, that with few lines of code we can customize string class from STL, as in, we can make it to treat 'a' and 'z' same, 'b' and 'y' same, 'c' and 'x' same and so on. Similary 'A' and 'Z' same etc. "abc" == "zyx" is true; "Abc" == "zyx" is false; "Abc == "Zyx" is true; etc I was thinking of implementing such string class, but I am not able to do so. How can we implement such string class using templates?

  Hello Geeks, I am developing some tool for BI. There are terms like Fact, Dimensions and Measures. My application will connect to the normal database and read the data from that table. Now, I want to convert all this data into columnar database. That is all the columns from this table will be transfer into 3 tables each. Consider below table:- ID Product 1 XYZ 2 ABC 3 ABC Now, I want to convert the Product column i.e. dimension into 3 tables. dim_product_table:- ID Product 1 XYZ 2 ABC dim_product_fmk(fact map by key):- Where we will store key-value pair of Key Row 1 1 1 2 2 3 dim_product_fmr(fact map by row):- The above table will be reversed.

  #include<stdio.h> #include<conio.h> #define ABC 20 #define XYZ 10 #define XXX ABC - XYZ void main() { int a; a = XXX * 10; printf("\n %d \n", a); getch(); } I thought the output should be 100 but when i saw the result i found o/p as -80. when i put bracket as #define XXX (ABC-XYZ) then i get output as 100 but without bracket i get o/p as -80.

• Trimming a vector of strings

  - by dreamlax

  I have an std::vector of std::strings containing data similar to this: [0] = "" [1] = "Abc" [2] = "Def" [3] = "" [4] = "Ghi" [5] = "" [6] = "" How can I get a vector containing the 4 strings from 1 to 4? (i.e. I want to trim all blank strings from the start and end of the vector): [0] = "Abc" [1] = "Def" [2] = "" [3] = "Ghi" Currently, I am using a forward iterator to make my way up to "Abc" and a reverse iterator to make my way back to "Ghi", and then constructing a new vector using those iterators. This method works, but I want to know if there is an easier way to trim these elements. P.S. I'm a C++ noob. Edit Also, I should mention that the vector may be composed entirely of blank strings, in which case a 0-sized vector would be the desired result.

• Regular expression match, extracting only wanted segments of string

  - by Ben Carey

  I am trying to extract three segments from a string. As I am not particularly good with regular expressions, I think what I have done could probably be done better... I would like to extract the bold parts of the following string: SOMETEXT: ANYTHING_HERE (Old=ANYTHING_HERE, New=ANYTHING_HERE) Some examples could be: ABC: Some_Field (Old=,New=123) ABC: Some_Field (Old=ABCde,New=1234) ABC: Some_Field (Old=Hello World,New=Bye Bye World) So the above would return the following matches: $matches[0] = 'Some_Field'; $matches[1] = ''; $matches[2] = '123'; So far I have the following code: preg_match_all('/^([a-z]*\:(\s?)+)(.+)(\s?)+\(old=(.+)\,(\s?)+new=(.+)\)/i',$string,$matches); The issue with the above is that it returns a match for each separate segment of the string. I do not know how to ensure the string is the correct format using a regular expression without catching and storing the match if that makes sense? So, my question, if not already clear, how I can retrieve just the segments that I want from the above string?

• iphone float vs integer rounding?

  - by Rob

  Okay, from what I understand, an integer that is a fraction will be rounded one way or the other so that if a formula comes up with say 5/6 - it will automatically round it to 1. I have a calculation: xyz = ((1300 - [abc intValue])/6) + 100; xyz is defined as an NSInteger, abc is an NSString that is chosen via a UIPicker. I want the calculation (1300 - [abc intValue]) to add 1 to 100 for each 6 units below 1300. For example, 1255 should result in xyz having a value of 100 and 1254 should result in a value of 101. Now, I understand that my formula above is wrong because of the rounding principles, but I am getting some CRAZY results from the program itself. When I punched in 1259 - I got 106. When I punched in 1255 - I got 107. Why would it behave that way?

• How to bind value to its parent element value?

  - by KentZhou

  Silverlight provides element to element binding. How to apply it this is case: I have a xaml as below: <TextBlock Text="{Binding ABC}" > <ToolTipService.ToolTip> <local:MyControl Title="{Binding ...}" /> </ToolTipService.ToolTip> </TextBlock> I want to bind MyControl Title to the same data as its parent Textblock Text, but I don't want set x:Name for its parent Textblock. I know there is one solution to bind Title to same data source: <local:MyControl Title="{Binding ABC}" /> This may cause two times to call "{Binding ABC}", with my case, there ValurConverter for this binding. I don't want to use this way.

• Get variable name as string in Perl

  - by Jose Cuervo

  Hi, I am trying to get a text representation of a variable's name. For instance, this would be the function I am looking for: $abc = '123'; $var_name = &get_var_name($abc); #returns '$abc' I want this because I am trying to write a debug function that recursively outputs the contents of a passed variable, I want it to output the variable's name before hand so if I call this debug function 100 times in succession there will be no confusion as to which variable I am looking at in the output. I have heard of Data::Dumper and am not a fan. If someone can tell me how to if it's possible get a string of a variable's name, that would be great. Thanks!

• Maximum number of files in one ext3 directory while still getting acceptable performance?

  - by knorv

  I have an application writing to an ext3 directory which over time has grown to roughly three million files. Needless to say, reading the file listing of this directory is unbearably slow. I don't blame ext3. The proper solution would have been to let the application code write to sub-directories such as ./a/b/c/abc.ext rather than using only ./abc.ext. I'm changing to such a sub-directory structure and my question is simply: roughly how many files should I expect to store in one ext3 directory while still getting acceptable performance? What's your experience? Or in other words; assuming that I need to store three million files in the structure, how many levels deep should the ./a/b/c/abc.ext structure be? Obviously this is a question that cannot be answered exactly, but I'm looking for a ball park estimate.

• Website access per client and each client having multiple users Sample Application

  - by windson

  I'm interested in building a web application in .NET that is scalable to multiple Clients and each and every Client has users associated with them. Suppose that my website is xyz.com and I have 3 clients "abc", "klm", "pqr" and I want to give access to features of xyz.com under the link as follows www.xyz.com/abc www.xyz.com/klm www.xyz.com/pqr and Client abc has N users and I want to set 3 roles for every client's user role. Is there any sample application in .NET that support this kind of website access per client having multiple users? And If I use ASP.NET Membership will that be a suitable membership solution or Do I need to opt for any other type of Membership defined by my own or already available in open source market for .NET. Edit: All the clients will have same functionality. I would like to build a generic model for www.xyz.com/{whatever} so that in future if a new client want to register with me he/she just have to give client name and up on adding client name all the features avaiable to exising clients will be applicable.

• Automatically registering "commands" for a command line program in python

  - by seandavi

  I would like to develop a command-line program that can process and give "help" for subcommands. To be concrete, say I have a single script called "cgent" and I would like to have subcommands "abc", "def", and "xyz" execute and accept the rest of the sys.args for processing by optparse. cgent abc [options] cgent help abc .... All of this is straightforward if I hard-code the subcommand names. However, I would like to be able to continue to add subcommands by adding a class or module (?). This is similar to the idea that is used by web frameworks for adding controllers, for example. I have tried digging through pylons to see if I can recreate what is done there, but I have not unravelled the logic. Any suggestions on how to do this? Thanks, Sean
