• Python - Find where in string regex match was found?

  - by nb

  I'm currently using regular expressions to search through RSS feeds to find if certain words and phrases are mentioned, and would then like to extract the text on either side of the match as well. For example: String = "This is an example sentence, it is for demonstration only" re.search("is", String) I'd like to know where the is was found so that I can extract and output something like this: 1 match found: "This is an example sentence" I know that it would be easy to do with splits, but I'd need to know what the index of first character of the match was in the string, which I don't know how to find

• Why can VS not display my WPF application in the designer, but it can run it just fine?

  - by Adam S

  This is absolutely ridiculous! Visual Studio is able to run (debug) my program just fine, but it won't display my layout in the designer. It just gives this useless error: Can anyone help explain this? I have not changed the XAML at all, not a single character, since the last time it worked fine. I've only changed some .cs code.

• Ajax auto-populate from field when another form field is filled out

  - by Jon

  Has anyone used javascript/ajax to take data from one form field and put it into another? I'm trying to create a form that when one text input is filled out a second is auto-populated with the first letter of the word that is in the first text input. I'm thinking I can limit the second text input to one character to help get the desired result, but I'm not having luck finding the javascript to get the second text input to auto-populate from the first. Any suggestions?

• Where does getopt_long store an unrecognized option?

  - by Rob Kennedy

  When getopt or getopt_long encounters an illegal option, it stores the offending option character in optopt. When the illegal option is a long option, where can I find out what the option was? And does anything meaningful get stored in optopt then? I've set opterr = 0 to suppress the automatically printed error message. I want to create my own message that I can print or log where I'd like, but I want to include the name of the unrecognized option.

• Censoring selected words (replacing them with ****) using a single replaceAll?

  - by aioobe

  I'd like to censor some words in a string by replacing each character in the word with a "*". Basically I would want to do String s = "lorem ipsum dolor sit"; s = s.replaceAll("ipsum|sit", $0.length() number of *)); so that the resulting s equals "lorem ***** dolor ***". I know how to do this with repeated replaceAll invokations, but I'm wondering, is this possible to do with a single replaceAll?
