  • HTML block nested in PHP if statement - is this considered bad practice?

    - by JYelton
    Consider the following example: <table> <tr> <td>Row One</td> </tr> <?php if ($rowtwo) { ?> <tr> <td>Row Two</td> </tr> <?php } ?> </table> If $rowtwo is true, the second row is output, otherwise it is skipped. The code works as desired, however I am evaluating Netbeans (7 beta) as a PHP IDE (instead of just using a text editor). Netbeans flags the code with an error: Misplaced non-space characters insided [sic] a table. Should I consider an alternate way of writing this code, or is Netbeans incapable of understanding this flow control wrapper for HTML output?

  • How to prevent illegal file and folder name creation in Windows Server 2003 or Windows Server 2008

    - by Joel Thibeault
    Preventing illegal file and Folder name creation on a Windows 2003/2008 file server is the goal. We know from articles like http://stackoverflow.com/questions/62771/how-check-if-given-string-is-legal-allowed-file-name-under-windows that for some reason the file system allows creation of illegal file/folder chacters and paths that exceed the limitations of Windows. I need the following question answered: How to remove cabability to create file or folder creation in NTFS that contains invalid characters? Can you remove the POSIX subsystem from Windows to fix this issue? How does disabling 8.3 dos name creation factor into this issue? Will any of these fixes prevent linux clients from creating windows compliant files?

  • How to pass a const unsigned char * from c++ to c#

    - by tzup
    So I have a function in unmanaged c++ that gets called when some text happens to have "arrived": #using <MyParser.dll> ... void dump_body(const unsigned char *Body, int BodyLen) { // Need to pass the body to DumpBody, but as what type? ... lMyParser::Parser::DumpBody(???); } DumpBody is a function defined in a C# DLL that should take one parameter of type? Body holds an array of characters (text) of length BodyLen. There's obviously some marshalling to be done here but I have no idea how. Please help.

  • Preserve trailing whitespace Sybase

    - by AngryWhenHungry
    I have a big chunk of textual data which I split and write multiple rows of a varchar(255) column of a table. Sometimes, the last character happens to be a space. When I read back this row, the trailing space is chopped and I get only 254 characters. This messes up my data when I append the next row to the end of this one. My code sends the full 255 char (incl space) to the DB API. How can I check that the trailing space is actually written to the table? I am not in a position to rewrite/redesign legacy code. Is there any setting - either in the DB, DB interface, read/write calls etc - that I can use to preserve the trailing space?

  • IE cannot download file with unicode pathname

    - by MM
    I have a web-app that allows users to upload and download image files by pressing buttons on a web page. A user of this page is reporting that IE 7 and 8 fail to download files when the files have Unicode pathnames. IE prompts the user with a dialog stating: "Internet explorer cannot download (file) at (webserver).". Unfortunately I have not been able to reproduce the problem using these versions on my machine. My question is, what could cause this, and how can I prevent it from happening? I have read about problems with cache control (I currently have it set to no-cache); however, I am not using HTTP-S, and the problem only occurs with file-names containing Unicode characters.

  • UnicodeDecodeError from a GET-parameter in webapp2

    - by Aneon
    I'm getting a UnicodeDecodeError when recieving a GET-parameter from webapp2 that contains unicode characters, and then using it to do a NDB query. I get the same error message when manually running a unicode() on the parameter in the handler, so there either seems to be a problem in webapp2's URL routing or I've missed something. Preferably, all GET-parameters should be converted to unicode before getting passed into the handler so I don't need to do manual conversions in all of my handlers. I actually think it's worked before in an earlier version. The full error message read: UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1: ordinal not in range(128) The GET-parameter contains the following string: göteborg. It looks fine when I raise an Exception on it, but gives me an error when I (or NDB) use unicode() on it. EDIT: In NDB, it fails on the following code: File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\datastore_types.py", line 1562, in PackString pbvalue.set_stringvalue(unicode(value).encode('utf-8')) Thanks.

  • excluding a column in csv file with regex

    - by JPro
    Is there any way to exclude/delete/replace one field from a csv file with some regexp in notepad++? I have a csv file with some data like this: '1','data1','data2','data3','data4','data5','data6','data7','data8','data9', 'data10','data11','data12','data13','data14','data15','data16','data17','data18', 'data19','data20','data21','data22','data23','\'data24 with some commas, here and there and some "double quotes", and fullstops.','data25','data26' The only problem I am facing is with data24 WHERE I encounter \' and then "" and some wild characters like , and .. This is particularly fixed at 24 field. For the purpose of clarity, I have entered a newline here. But the entire text above is in juts one line. Any ideas on how to solve? Thanks.

  • Javascript regular expressions problem

    - by Patrick
    Hello! I am creating a small yatzy game and i have run into some regex problems. I need to verify certain criteria to see if they are met. The fields one to six is very straight forward the problem comes after that. Like trying to create a regex that matches the ladder. The Straight should contain one of the following characters 1-5. It must contain one of each to pass but i can't figure out how to check for it. I was thinking /1{1}2{1}3{1}4{1}5{1}/g; but that only matches if they come in order. How can i check if they don't come in the correct order?

  • Making swedish characthers show properly in Windows Command Prompt using Python in Notepad++

    - by Alex
    The title explains it well. I have set up Notepad++ to open the python script in the command prompt when I press F8 but all Swedish characters looks messed up when opening in CMD but perfectly fine in e.g IDLE. This simple example code: #!/usr/bin/env python #-*- coding: UTF-8 -*- print "åäö" Looks like this. As you can see the output of the bath file I use to open Python in cmd below shows the characthers correctly but not the python script above it. How do i fic this?

  • Working with Japanese filenames in PHP 5.3 and Windows Vista?

    - by Jon
    I'm currently trying to write a simple script that looks in a folder, and returns a list of all the file names in an RSS feed. However I've hit a major wall... Whenever I try to read filenames with Japanese characters in them, it shows them as ?'s. I've tried the solutions mentioned here: http://stackoverflow.com/questions/482342/php-readdir-problem-with-japanese-language-file-name - however they do not work for some reason, even with: header('Content-Type: text/html; charset=UTF-8'); setlocale(LC_ALL, 'en_US.UTF8'); mb_internal_encoding("UTF-8"); At the top (Exporting as plain text until I can sort this out). What can I do? I need this to work and I don't have much time.

  • clever way to conditionally split this string?

    - by sprugman
    I've got a string that could be in one of two forms: prefix=key=value (which could have any characters, including '=') or key=value So I need to split it either on the first or second equals sign, based on a boolean that gets set elsewhere. I'm doing this: if ($split_on_second) { $parts = explode('=', $str, 3); $key = $parts[0] . '=' . $parts[1]; $val = $parts[2]; } else { $parts = explode('=', $str, 2); $key = $parts[0]; $val = $parts[1]; } Which should work, but feels inelegant. Got any better ideas in php? (I imagine there's a regex-ninja way to do it, but I'm not a regex-ninja.;-)

  • What are the advantages of squashing assignment and error checking in one line?

    - by avakar
    This question is inspired by this question, which features the following code snippet. int s; if((s = foo()) == ERROR) print_error(); I find this style hard to read and prone to error (as the original question demonstrates -- it was prompted by missing parentheses around the assignment). I would instead write the following, which is actually shorter in terms of characters. int s = foo(); if(s == ERROR) print_error(); This is not the first time I've seen this idiom though, and I'm guessing there are reasons (perhaps historical) for it being so often used. What are those reasons?

  • Permissions for Large Variables to Be Sent Via Stored Procedures (SQL Server)

    - by Joe Majewski
    I can't figure out a way to allow more than 4000 bytes to be received at once via a call to a stored procedure. I am storing images in the table that are around 15 - 20 kilobytes each, but upon getting them and displaying them to the page, they are always exactly 3.91 KB in size (or 4000 bytes). Do stored procedures have a limit on how much data can be sent at once? I double-checked my data, and I am indeed only receiving the first 4000 characters from the varbinary(MAX) field. Is there a permission setting to allow more than 4k bytes at once?

  • How can I do a 'where' clause in Linux shell?

    - by Hoa
    I have a CSV file and I would like to filter all the lines where the 19th column has two or more characters. I know the individual pieces but can't figure out how to glue them together. First I have to cat the file. The following prints the 19th column awk -F "," '{print $19}' file.txt awk also has length and ifs And I know it all has to be glued together using pipes. I'm just getting stuck at the exact syntax since I have not done much bash programming before.

  • Bash intercepting wildcard in script

    - by MrRoth
    I am using Bash script to read line by line from a text file, which has special characters in it (regular expression). When I use echo "${SOME_VAR}" it does not display the text as is. I am familiar with Prevent * to be expanded in the bash script. How can I display and use the text as is? UPDATE The text (TSV) file holds tuples similar to (the last entry is a psql query) bathroom bathroom select name from photos where name ~* '\mbathroom((s)?|(''s)?)\M'; I am reading the CSV as follows: tail -n+2 text.file | while IFS=$'\t' read x y z do echo "${z}" done which gives the output select name from photos where name ~* 'mbathroom((s)?|(''s)?)M'); note that the '\' is missing

  • Unique identification string in php

    - by NardCake
    Currently me and my friend are developing a website, for what we will call 'projects' we just have a basic auto increment id in the database used to navigate to projects such as oururl.com/viewproject?id=1 but we started thinking, if we have alot of posted projects thats going to be a LONG url. So we need to somehow randomly generate a alphanumerical string about 6 characters long. We want the chance of the string being duplicated being extremely low and of course we will query the database before assigning an identifier. Thanks for anyhelp, means alot!

  • Should I convert overly-long UTF-8 strings to their shortest normal form?

    - by Grant McLean
    I've just been reworking my Encoding::FixLatin Perl module to handle overly-long UTF-8 byte sequences and convert them to the shortest normal form. My question is quite simply "is this a bad idea"? A number of sources (including this RFC) suggest that any over-long UTF-8 should be treated as an error and rejected. They caution against "naive implementations" and leave me with the impression that these things are inherently unsafe. Since the whole purpose of my module is to clean up messy data files with mixed encodings and convert them to nice clean utf8, this seems like just one more thing I can clean up so the application layer doesn't have to deal with it. My code does not concern itself with any semantic meaning the resulting characters might have, it simply converts them into a normalised form. Am I missing something. Is there a hidden danger I haven't considered?

  • How to handle #(hash) character in SEO friendly url?

    - by arvinsim
    How do you bypass the default behaviour if #(hash) which is to go to a specific part of a page? The problem that I have is that the # character is a part of the SEO friendly url which is a title and the #(hash) is part of the content (i.e. like with C#). I can't retrieve the whole string and I only get the characters before the #. Example: www.domain.com/C#-programming-book in this example I only get 'C' and not the '-programming-book' part. I am not using any javascript at the moment and would like to only use a PHP solution for this. Before anyone suggests that I used url encoding, the criteria for the seo friendly url is that it should be human readable and easily remembered. So converting the hash to '%23' does not pass the criteria. Is there no way around it?

  • Why are regular expressions such a complicated, cryptic mess?

    - by steffenj
    Often when I see regular expressions, I only see a total mess of characters. Why does it have to be this way? I guess what I really want to know is: are there alternatives to regular expressions that basically do the same thing but are implemented in a human readable language? [UPDATE] Thanks for all the great responses and inspiration! I wanted to highlight this particular link which shows how a (working) alternative would look like, which may also be a good starting point for learning or "simple" regex expressions. But you also quickly get a feel for the verbosity tradeoff.

  • One on One table relation - is it harmful to keep relation in both tables?

    - by EBAGHAKI
    I have 2 tables that their rows have one on one relation.. For you to understand the situation, suppose there is one table with user informations and there is another table that contains a very specific informations and each user can only link to one these specific kind of informations ( suppose second table as characters ) And that character can only assign to the user who grabs it, Is it against the rules of designing clean databases to hold the relation key in both tables? User Table: user_id, name, age, character_id Character Table: character_id, shape, user_id I have to do it for performance, how do you think about it?

  • How to replace the char '[' etc with '\[' using "sed" in a file ?

    - by Abhijeet
    I have a file say "file.txt" with following contents: Capsule arr**[**0**]** in state A rate_ul/dl=**(**2000000/7000000**)** Capsule RBx**[**0**]** in state ... ... using sed operator how can i replace all occurences of '[' with '[', '(' with '(', ']' with ']' and so on. Capsule arr**\[**0**\]** in state A rate_ul/dl=**\(**2000000/7000000**\)** Capsule RBx**\[**0**\]** in state ... ... Using the substitue operator in "gvim" I am able to achieve the same result. ie. if i use ":1,$ s/\[/\\[/g" in the vi editor in command mode I see all the '[' chars replaced with '['. However if I try to use the same substitue command in a shell script using a sed command, i am not able to achieve the same result. ie If i use the following command in a shell script I am not able to achieve the desired result: sed "s/\[/\\[/g" $temp_file2 > $temp_file1 where $temp_file2 conatins the lines with '[' characters and $temp_file1 should contain the replaced '\[' chars

  • How do I specify a wildcard (for ANY character) in a c# regex statement?

    - by Scott
    Trying to use a wildcard in C# to grab information from a webpage source, but I cannot seem to figure out what to use as the wildcard character. Nothing I've tried works! The wildcard only needs to allow for numbers, but as the page is generated the same every time, I may as well allow for any characters. Regex statement in use: Regex guestbookWidgetIDregex = new Regex("GuestbookWidget(' INSERT WILDCARD HERE ', '(.*?)', 500);", RegexOptions.IgnoreCase); If anyone can figure out what I'm doing wrong, it would be greatly appreciated!
