• Specifying Cell Format in CSV File

  - by Someone

  I am generating a csv file from a PHP array. It opens just fine in Excel and OpenOffice Calc, however the data in one of the column are zip codes. Excel makes the cell formats of the column number general by default. This results in the leading 0 getting dropped in zip codes. Is there any way I can specify the cell formats within the CSV file?

• AESlibrary only two lines

  - by user303968

  Does anyone know a c++ library that uses advanced encryption standard encryption that can achieve encryption and decryption (using counter mode) in just two lines of codes. No need of padding or buffering the plaintexts the library will take care of all this. I have had a look at crypto++, openssl and libtomcrypt but in these it seems I need to write codes to buffer and pad the plaintexts which I don't want. In brief, I need something along these lines: ciphertext = encrypt(ctr_mode(),plaintext,key) plaintext = decrypt(ctr_mode(),ciphertext,key) Thanks!

• Why is "copy and paste" of code dangerous?

  - by Yigang Wu

  Sometimes, my boss will complain us why we need so long time to implement a feature. Actually, the feature has been implemented in other AP before, you just need to copy and paste codes from there. The cost should be low. It's really a hard question, because copy and paste codes is not a easy thing from my point. Do you have any good reason to explain your boss who doesn't know technology?

• Whats the best way to send multiple variables in a query string within a URL

  - by Andy

  I have a client who is wanting to create a link which contains product codes so that his customers hit a page with just those products displayed in an attempt to increase conversion rates from affilliate sites. My question is whats the best way to send these multiple products in a single URL For example: http://www.mydomain.co.uk/bespoke-list.php?catNo=234-324-232-343 Obviously then the site would grab the codes from the string and display them... We're going to be using PHP! Thanks in advance.

• Any WSGI middleware to make HTTP redirect on specific status code?

  - by Evgenyt

  I'm using Pylons and want to add some middleware to it so that it catches 401 status codes and makes HTTP Redirect (302) to Signin page. I know there is built-in StatusCodeRedirect in Pylons that acts in a similar fashion, but it does not produce HTTP redirect, and rather redirects internally (this is what I do not want). Is there any existing middleware to add, or any generic middleware that can be easily modified to make HTTP redirects on specific status codes?

  - by Adam S

  I've used a few F/OSS libraries in my commercial application. As per their licenses, I am obligated to include their source codes along with my VS2008 application. This is my first time making a "real" commercial application, and I would appreciate some advice on how best to go about including their source codes. I don't want to package them as zip files alongside my installed. I still want my installer to be a single file.

• String replace for personalize code generator

  I must do a automatic codes generator with user-configurable string with predefined keys and can not find a good way to do it. For example, a string OT-{CustomCode}-{Date}-{##} could generate codes OT-C0001-20100420-01 OT-C0001-20100420-02 I thought of using RegExpr.Replace(), but I would have problems if the code of a customer was {##} Any help is welcome!

  let's say I have a list li = [{'q':'apple','code':'2B'}, {'q':'orange','code':'2A'}, {'q':'plum','code':'2A'}] What is the most efficient way to return the count of unique "codes" in this list? In this case, the unique codes is 2, because only 2B and 2A are unique. I could put everything in a list and compare, but is this really efficient?

• C#: Multiline TextBox with TextBox.WordWrap Displaying Long Base64 String

  - by Peter Lee

  Hi, Happy New Year! I have a textbox to display a very long Base64 string. The TextBox.Multline = true and TextBox.WordWrap = true. The issue is caused by the auto-word-boundary detection of the TextBox itself. The Base64 string has '+' as one of the 64 characters for Base64 encoding. Therefore, the TextBox will wrap it up at the '+' character, which is not what I want (because the use might think there is a newline character around the '+' character). I just want my Base64 string displayed in Mulitline-mode in TextBox, but no word boundary detection, that is, if the TextBox.Width can only contain 80 characters, then each line should have exact 80 characters except the last line. I'm not sure if I made myself clear. Thanks. Peter

• Java char literal to C# char literal

  - by Kristoffersen

  Hi. I am maintaining some Java code that I am currently converting to C#. The Java code is doing this: sendString(somedata + '\000'); And in C# I am trying to do the same: sendString(somedata + '\000'); But on the '\000' VS2010 tells me that "Too many characters in character literal". How can I use '\000' in C#? I have tried to find out what the character is, but it seems to be " " or some kind of newline-character. Do you know anything about the issue? Thanks!

• PHP string manipulation, inside the string

  - by James

  I have string: ABCDEFGHIJK And I have two arrays of positions in that string that I want to insert different things to. Array ( [0] => 0 [1] => 5 ) Array ( [0] => 7 [1] => 9 ) Which if I decided to add the # character and the = character, it'd produce: #ABCDE=FG#HI=JK Is there any way I can do this without a complicated set of substr? Also, # and = need to be variables that can be of any length, not just one character.
