• PL/SQL REGEXP_LIKE testing string for allowed characters

  - by Arino

  I need to verify that the provided string has only allowed characters using Oracle regular expressions (REGEXP_LIKE). Allowed chars are: abcdefghijklmnopqrstuvwxyz0123456789_-. Trying to execute SELECT CASE WHEN REGEXP_LIKE('abcdefghijklmnopqrstuvwxyz0123456789_-.' , '^[a-z0-9_\-\.]+$') THEN 'true' ELSE 'false' END tmp FROM dual; results in 'false'. Any ideas on this?

• Get current Apache version string for display

  - by Stijn Sanders

  I'm writing an Apache module and want to get a string with the Apache name version and other details. Much like what gets added to outgoing headers, e.g.: Server: Apache/2.2.13 (Win32) I've tried code like this: apr_table_get(request_rec->headers_out,"Server") But that doesn't seem to work. Is there an API call I haven't found or am I doomed to get version resource data from httpd.exe?

• PHP - Check for whitespace at beginning of string

  - by ITg

  I need to use preg_match to check that only a-z0-9. is used (including full stop(.)). I don't want to replace anything. My problem is that it doesn't notice white space at beginning of a string. Also, if anyone knows how to check there is no two full stops in a row, I would be very grateful. What I have so far: ("/[^a-z0-9.]+$/",$request) Thanks !

• C++ problem with string stream istringstream

  - by user69514

  I am reading a file in the following format 1001 16000 300 12.50 2002 24000 360 10.50 3003 30000 300 9.50 where the items are: loan id, principal, months, interest rate. I'm not sure what it is that I am doing wrong with my input string stream, but I am not reading the values correctly because only the loan id is read correctly. Everything else is zero. Sorry this is a homework, but I just wanted to know if you could help me identify my error. if( inputstream.is_open() ){ /** print the results **/ cout << fixed << showpoint << setprecision(2); cout << "ID " << "\tPrincipal" << "\tDuration" << "\tInterest" << "\tPayment" <<"\tTotal Payment" << endl; cout << "---------------------------------------------------------------------------------------------" << endl; /** assign line read while we haven't reached end of file **/ string line; istringstream instream; while( inputstream >> line ){ instream.clear(); instream.str(line); /** assing values **/ instream >> loanid >> principal >> duration >> interest; /** compute monthly payment **/ double ratem = interest / 1200.0; double expm = (1.0 + ratem); payment = (ratem * pow(expm, duration) * principal) / (pow(expm, duration) - 1.0); /** computer total payment **/ totalPayment = payment * duration; /** print out calculations **/ cout << loanid << "\t$" << principal <<"\t" << duration << "mo" << "\t" << interest << "\t$" << payment << "\t$" << totalPayment << endl; } }

• Does -localizedDescription of NSError return the actual localized string, or does it return a key fo

  - by mystify

  Must I do something like this? NSString *errorDescription = [error localizedDescription]; NSString *errorInfoStr = NSLocalizedString(errorDescription, nil); Or do I use NSLocalizedString already when populating the userInfo dictionary with the NSLocalizedDescriptionKey key and value? So the value for that is not actually a key for NSLocalizedString, but it is the actual localized string ready to show up on screen?

  - by tzippy

  I am reading a file by line and need to extract latitude and longitude from it. This how lines can looks: DE 83543 Rott am Inn Bayern BY Oberbayern Landkreis Rosenheim 47.983 12.1278 DE 21147 Hamburg Hamburg HH Kreisfreie Stadt Hamburg 53.55 10 What's for sure is, there are no dots surrounded by digits except for the ones representing the doubles.
