Is it possible to get a pointer to String^'s internal array in C++/CLI?

- by CannibalSmith

The goal is to avoid copying the string data when I need a const wchar_t*. The answer seems to be yes, but the function PtrToStringChars doesn't have its own MSDN entry (it's only mentioned in the KB and blogs as a trick). That made me suspicious and I want to check with you guys. Is it safe to use that function?

T-SQL Tuesday # 16 : This is not the aggregate you're looking for

- by AaronBertrand

This week, T-SQL Tuesday is being hosted by Jes Borland ( blog | twitter ), and the theme is " Aggregate Functions ." When people think of aggregates, they tend to think of MAX(), SUM() and COUNT(). And occasionally, less common functions such as AVG() and STDEV(). I thought I would write a quick post about a different type of aggregate: string concatenation. Even going back to my classic ASP days, one of the more common questions out in the community has been, "how do I turn a column into a comma-separated...(read more)

Find a non-case-sensitive text string within a range of cells

- by Iszi

I've got a bit of a problem to solve in Excel, and I'm not quite sure how to go about doing it. I've done a few searches online, and haven't really found any formulas that seem to be useful. Here's the situation (simplified just a bit, for the purpose of this question): I have data in columns A-E. I need to match data in the cells in A and B, with data in C-E, and return TRUE or FALSE to column F. Return TRUE if: - The string in A is found within any string in C-E. OR - The string in B is found within any string in C-E. Otherwise, return FALSE. The strings must be exact matches for whole or partial strings within the range, but the matching function must be case-insensitive. I've taken a screenshot of an example sheet for reference. I'm fairly sure I'll need to use IF or on the outermost layer of the formula, probably followed by OR. Then, for the arguments to OR, I'm expecting there will be some use of IFERROR involved. But what I'm at a loss for is the function I could most efficiently use to handle the text string searches. VLOOKUP is very limited in this regard, I think. It may be workable to do whole-string against whole-string comparisons, but I'm fairly certain it won't return accurate results for partial string matches. FIND and SEARCH appear limited to only single-target searches, and are also case-sensitive. I suppose I could use UPPER or LOWER to force case-insensitivity in the search, but I still need something that can do accurate partial matching and search a specified range of cells. Is there any function, or combination of functions, that could work here? Ideally, I want to do this with a straight Excel formula. I'm not at all familiar with VBScript or similar tools, nor do I have time to learn it for this project.

Concat wchar_t Unicode strings in C?

- by Doori Bar

I'm a beginner, I play with FindFirstFileW() of the winapi - C. The unicoded path is: " \\?\c:\Français\", and I would like to concat "*" to this path of type wchar_t (then I will use it as an arg for FindFirstFileW()). I made two test cases of mine, the first is ansi_string() which seem to work fine, the second is unicode_string() - which I don't quite understand how should I concat the additional "*" char to the unicoded path. I write the strings to a file, because I'm not able to print Unicoded characters to stdout. Note: my goal is to learn, which means I'll appreciate guidance and references to the appropriate resources regards my scenario, I'm very much a beginner and this is my first attempt with Unicode.

Don’t string together XML

- by KyleBurns

XML has been a pervasive tool in software development for over a decade. It provides a way to communicate data in a manner that is simple to understand and free of platform dependencies. Also pervasive in software development is what I consider to be the anti-pattern of using string manipulation to create XML. This usually starts with a “quick and dirty” approach because you need an XML document and looks like (for all of the examples here, we’ll assume we’re writing the body of a method intended to take a Contact object and return an XML string): return string.Format("<Contact><BusinessName>{0}</BusinessName></Contact>", contact.BusinessName); In the code example, I created (or at least believe I created) an XML document representing a simple contact object in one line of code with very little overhead. Work’s done, right? No it’s not. You see, what I didn’t realize was that this code would be used in the real world instead of my fantasy world where I own all the data and can prevent any of it containing problematic values. If I use this code to create a contact record for the business “Sanford & Son”, any XML parser will be incapable of processing the data because the ampersand is special in XML and should have been encoded as &. Following the pattern that I have seen many times over, my next step as a developer is going to be to do what any developer in his right mind would do – instruct the user that ampersands are “bad” and they cannot be used without breaking computers. This may work in many cases and is often accompanied by logic at the UI layer of applications to block these “bad” characters, but sooner or later someone is going to figure out that other applications allow for them and will want the same. This often leads to the creation of “cleaner” functions that perform a replace on the strings for every special character that the person writing the function can think of. The cleaner function will usually grow over time as support requests reveal characters that were missed in the initial cut. Sooner or later you end up writing your own somewhat functional XML engine. I have never been told by anyone paying me to write code that they would like to buy a somewhat functional XML engine. My employer/customer’s needs have always been for something that may use XML, but ultimately is functionality that drives business value. I’m not going to build an XML engine. So how can I generate XML that is always well-formed without writing my own engine? Easy – use one of the ones provided to you for free! If you’re in a shop that still supports VB6 applications, you can use the DomDocument or MXXMLWriter object (of the two I prefer MXXMLWriter, but I’m not going to fully describe either here). For .Net Framework applications prior to the 3.5 framework, the code is a little more verbose than I would like, but easy once you understand what pieces are required: using (StringWriter sw = new StringWriter()) { using (XmlTextWriter writer = new XmlTextWriter(sw)) { writer.WriteStartDocument(); writer.WriteStartElement("Contact"); writer.WriteElementString("BusinessName", contact.BusinessName); writer.WriteEndElement(); // end Contact element writer.WriteEndDocument(); writer.Flush(); return sw.ToString(); } } Looking at that code, it’s easy to understand why people are drawn to the initial one-liner. Lucky for us, the 3.5 .Net Framework added the System.Xml.Linq.XElement object. This object takes away a lot of the complexity present in the XmlTextWriter approach and allows us to generate the document as follows: return new XElement("Contact", new XElement("BusinessName", contact.BusinessName)).ToString(); While it is very common for people to use string manipulation to create XML, I’ve discussed here reasons not to use this method and introduced powerful APIs that are built into the .Net Framework as an alternative. I’ve given a very simplistic example here to highlight the most basic XML generation task. For more information on the XmlTextWriter and XElement APIs, check out the MSDN library.

python raw_input odd behavior with accents containing strings

- by Ryan

I'm writing a program that asks the user for input that contains accents. The user input string is tested to see if it matches a string declared in the program. As you can see below, my code is not working: code # -*- coding: utf-8 -*- testList = ['má'] myInput = raw_input('enter something here: ') print myInput, repr(myInput) print testList[0], repr(testList[0]) print myInput in testList output in eclipse with pydev enter something here: má mv° 'm\xe2\x88\x9a\xc2\xb0' má 'm\xc3\xa1' False output in IDLE enter something here: má má u'm\xe1' má 'm\xc3\xa1' Warning (from warnings module): File "/Users/ryanculkin/Desktop/delete.py", line 8 print myInput in testList UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal False How can I get my code to print True when comparing the two strings? Additionally, I note that the result of running this code on the same input is different depending on whether I use eclipse or IDLE. Why is this? My eventual goal is to put my program on the web; is there anything that I need to be aware of, since the result seems to be so volatile?

jQuery: shorten string length to fit a set width.

- by Marius

Hello there, I have a table, and in each cell I want to place strings, but they are much wider than the cell width. To prevent line break, I would like to shorten the strings to fit the cell, and append '...' at end to indicate that the string is much longer. The table has about 40 rows and has to be done to each cell, so its important that its a quick. Should I use JS/jQuery for this? How would I do it? Thank you for your time. Kind regards, Marius

Problem with boost::find_format_all, boost::regex_finder and custom regex formatter (bug boost 1.42)

- by Nikko

I have a code that has been working for almost 4 years (since boost 1.33) and today I went from boost 1.36 to boost 1.42 and now I have a problem. I'm calling a custom formatter on a string to format parts of the string that match a REGEX. For instance, a string like: "abc;def:" will be changed to "abc\2Cdef\3B" if the REGEX contains "([;:])" boost::find_format_all( mystring, boost::regex_finder( REGEX ), custom_formatter() ); The custom formatter looks like this: struct custom_formatter() { template< typename T > std::string operator()( const T & s ) const { std::string matchStr = s.match_results().str(1); // perform substitutions return matchStr; } } This worked fine but with boost 1.42 I know have "non initialized" s.match_results() which yield to boost::exception_detail::clone_implINS0_::error_info_injectorISt11logic_errorEEEE - Attempt to access an uninitialzed boost::match_results< class. This means that sometimes I am in the functor to format a string but there is no match. Am I doing something wrong? Or is it normal to enter the functor when there is no match and I should check against something? for now my solution is to try{}catch(){} the exception and everything works fine, but somehow that doesn't feel very good. EDIT1 Actually I have a new empty match at the end of each string to parse. EDIT2 : one solution inspired by ablaeul template< typename T > std::string operator()( const T & s ) const { if( s.begin() == s.end() ) return std::string(); std::string matchStr = s.match_results().str(1); // perform substitutions return matchStr; } *EDIT3 Seems to be a bug in (at least) boost 1.42 *

Marshal.StringToCoTaskMemAnsi converting non-Latin characters when sending raw data to a printer

- by rem

For sending raw data to a thermal DATAMAX printer I'm using RawPrinterHelper class from this Microsoft KB article. When a string sent to printer contains only Latin characters, everything is OK. But non-Latin, in my case Russian characters in a string, are not printed correct. I think the problem is in using Marshal.StringToCoTaskMemAnsi method for converting the string: public static bool SendStringToPrinter(string szPrinterName, string szString) { IntPtr pBytes; Int32 dwCount; // How many characters are in the string? dwCount = szString.Length; // Assume that the printer is expecting ANSI text, and then convert // the string to ANSI text. pBytes = Marshal.StringToCoTaskMemAnsi(szString); // Send the converted ANSI string to the printer. SendBytesToPrinter(szPrinterName, pBytes, dwCount); Marshal.FreeCoTaskMem(pBytes); return true; } Just to note, Russian characters in the string are put in hex format, like "\x83", but nevertheless the method doesn't put this hex value in unmanaged memory as it is, but converts it, I think, according with ANSI code page to a character and then printer can not read it correctly. If I try to compose a file, using Hex editor and put correct hex values in place of non-Latin characters and then send the file to a printer using another method from the same class SendFileToPrinter, everything, including Russian characters is printed correctly. How in this case the problem with sending string, containing non-Latin characters, could be solved?

Using Regex, how can I remove certain characters from the inside of tags in a string of html?

- by Iain Fraser

Suppose I have a string of html that contains a bunch of control characters and I want to remove the control characters from inside tags only, leaving the characters outside the tags alone. For example Here the control character is the numeral "1". Input The quick 1orange lemming <sp11a1n 1class1='jumpe111r'11>jumps over 1the idle 1frog Desired Output The quick 1orange lemming jumps over 1the idle 1frog So far I can match tags which contain the control character but I can't remove them in one regex. I guess I could perform another regex on my matches, but I'd really like to know if there's a better way. My regex Bear in mind this one only matches tags which contain the control character. <(([^>])*?`([^>])*?)*?> Thanks very much for your time and consideration. Iain Fraser

How can I set the minDate/maxDate for jQueryUI Datepicker using a string?

- by leo

jQueryUI Datepicker documentation states that the minDate option can be set using "a string in the current dateFormat". So I've tried the following to initialize datepickers: $("input.date").datepicker({ minDate: "01/01/2010", maxDate: "12/31/2010" }); However, this results in my datepicker having a selectable date range that goes from 11/06/2015 to 12/17/2015. I've checked the current dateformat and its mm/dd/yy, which is supposed to mean 2 digits for the month, 2 for the day, and 4 for the year, separated by slashes. I've also tried including dateFormat: "mm/dd/yy" in the inizialization statement. I've also checked the values for minDate and maxDate afterwards and they ARE being set to the values I want: 01/01/2010 and 12/31/2010. I want to be able to set min/maxDate with strings because I'm being passed these values as strings from somewhere else. Maybe someone knows why this happens and how to solve this, or a workaround to achieve this, perphaps changing the format of the date strings or something? Thanks EDIT: Using: jQuery v1.3.2 and jQuery UI v1.7.2

regular expression search in python

- by Richard

Hello all, I am trying to parse some data and just started reading up on regular Expressions so I am pretty new to it. This is the code I have so far String = "MEASUREMENT 3835 303 Oxygen: 235.78 Saturation: 90.51 Temperature: 24.41 DPhase: 33.07 BPhase: 29.56 RPhase: 0.00 BAmp: 368.57 BPot: 18.00 RAmp: 0.00 RawTem.: 68.21" String = String.strip('\t\x11\x13') String = String.split("Oxygen:") print String[1] String[1].lstrip print String[1] What I am trying to do is to do is remove the oxygen data (235.78) and put it in its own variable using an regular expression search. I realize that there should be an easy solution but I am trying to figure out how regular expressions work and they are making my head hurt. Thanks for any help Richard

How to get all words of a string in c#?

- by Joseph Lafuente

I have a paragraph in a single string and I'd like to get all the words in that paragraph. My problem is that I don't want the suffixes words that end with punctuation marks such as (',','.',''','"',';',':','!','?') and /n /t etc. I also don't want words with 's and 'm such as world's where it should only return world. In the example he said. "My dog's bone, toy, are missing!" the list should be: he said my dog bone toy are missing

PHP Fatal error, trying to request method inside model multiple times

- by Tom

The error message [23-Mar-2010 08:36:16] PHP Fatal error: Cannot redeclare humanize() (previously declared in /Users/tmclssns/Sites/nadar/nadar/trunk/webapp/application/filer/models/Filer/Aggregate.php:133) in /Users/tmclssns/Sites/nadar/nadar/trunk/webapp/application/filer/models/Filer/Aggregate.php on line 133 I have a "Filer" model which contains several methods to generate graphs. Each method in there related to generating graphs has the suffix "Graph" in the method name. As we have some performance issues, I try to render the graphs in advance (using cron) instead of rendering them on each request. The code below is what I came up with: public function generategraphsAction() { $this->_helper->viewRenderer->setNoRender(); $config = Zend_Registry::get('config'); $id = $this->_getParam('filerid'); $filer = new Filer($id); $filer_methods = get_class_methods($filer); foreach ($filer_methods as $filer_method) { if (preg_match('/^(.*)Graph$/i', $filer_method, $matches)) { $path = $config->imaging_caching_dir . "/$id/{$matches[1]}.png"; $filer->$matches[0]($path); } } // var_dump(get_class_methods($filer)); die; } The result from the var_dump(), when uncommented, is: array 0 => string '__construct' (length=11) 1 => string 'find_by_name' (length=12) 2 => string 'getPartner' (length=10) 3 => string 'getSlots' (length=8) 4 => string 'getGroups' (length=9) 5 => string 'grouplist' (length=9) 6 => string 'getAggregates' (length=13) 7 => string 'getVolumes' (length=10) 8 => string 'getAggregateVolumes' (length=19) 9 => string 'getShelves' (length=10) 10 => string 'getAutoSupportHistory' (length=21) 11 => string 'getAutoSupportMail' (length=18) 12 => string 'getOrphans' (length=10) 13 => string 'getAll' (length=6) 14 => string 'getDiskRevOverview' (length=18) 15 => string 'getDiskTypeOverview' (length=19) 16 => string 'getDiskTypeSizeFunctionOverview' (length=31) 17 => string 'getLicenses' (length=11) 18 => string 'removeGroup' (length=11) 19 => string 'addGroup' (length=8) 20 => string 'hasGroup' (length=8) 21 => string 'aggdefaultGraph' (length=15) 22 => string 'aggbarGraph' (length=11) 23 => string 'voldefaultGraph' (length=15) 24 => string 'volbarGraph' (length=11) 25 => string 'replicationGraph' (length=16) 26 => string 'getReplicationData' (length=18) 27 => string 'humanize' (length=8) 28 => string 'getFiler' (length=8) 29 => string 'getOptions' (length=10) 30 => string 'getCifsInfo' (length=11) 31 => string 'getCifsStats' (length=12) 32 => string '__get' (length=5) 33 => string 'tr' (length=2) 34 => string 'trs' (length=3) 35 => string 'fieldList' (length=9) The generategraphsAction() method finds the 'Graph' methods correctly: array 0 => string 'aggdefaultGraph' (length=15) 1 => string 'aggdefault' (length=10) array 0 => string 'aggbarGraph' (length=11) 1 => string 'aggbar' (length=6) array 0 => string 'voldefaultGraph' (length=15) 1 => string 'voldefault' (length=10) array 0 => string 'volbarGraph' (length=11) 1 => string 'volbar' (length=6) array 0 => string 'replicationGraph' (length=16) 1 => string 'replication' (length=11) However when the first graph is generated, it generates the above listed PHP fatal error. Anyone can come up with a solution to this? I tried to pass by reference or switch a few things around (like re declare the Filer model, $current_filer = new Filer($id); and unset() it again after the request, but resulted in the same error) without much success. The referenced method "humanize" isn't used for anything I'm doing at the moment, but belongs to the Model because it's used in several other places. Of course, removing the method is not really an option right now, and the model contains several other methods as well so I assume if I just move the humanize method around, it will generate an error on the next one. For reference, the humanize() method: public function humanize ($kbytes, $unit = null) { // KiloByte, Megabyte, GigaByte, TeraByte, PetaByte, ExaByte, ZettaByte, YottaByte $units = array('KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'); if (null !== $units) { $i = array_search(substr($unit, -2), $units); if (! $i) { $i = floor((strlen($kbytes) - 1) / 3); } } else { $i = floor((strlen($kbytes) - 1) / 3); } $newSize = round($kbytes / pow(1024, $i), 2); return $newSize . $units[$i]; } Thanks in advance for the help offered.
