  • How to extract substrings with PHP

    - by shin
    PHP beginner's question. I need to keep image paths as following in the database for the admin backend. ../../../../assets/images/subfolder/myimage.jpg However I need image paths as follows for the front-end. assets/images/subfolder/myimage.jpg What is the best way to change this by PHP? I thought about substr(), but I am wondering if there is better ways. Thanks in advance.

  • Can't append space at end of UITextView

    - by Sam V
    I have a UITextView in which I want the initial value to be "@username " (notice the space after the username). This way the user can start typing right away without having to tap space. So I do: textView.text = [NSString stringWithFormat:@"@%@ ", username]; But it seems like it's impossible to have the UITextView text property ending with a space (it always gets stripped out). Am I correct? Is there any workaround for this? I tried using the \s char and no success.

  • can't insert xml dml expression as a string

    - by 81967
    Here is the code below that would explain you the problem... I create a table below with an xml column and declare a variable, initialize it and Insert the Value into the xml column, create table CustomerInfo (XmlConfigInfo xml) declare @StrTemp nvarchar(2000) set @StrTemp = '<Test></Test>' insert into [CustomerInfo](XmlConfigInfo) values (@StrTemp) Then comes the part of the question,, if I write this... update [CustomerInfo] set XmlConfigInfo.modify('insert <Info></Info> into (//Test)[1]') -- Works Fine!!! but when I try this, set @StrTemp = 'insert <Info></Info> into (//Test)[1]' update [CustomerInfo] set XmlConfigInfo.modify(@StrTemp) -- Doesn't Work!!! and throws an error The argument 1 of the xml data type method "modify" must be a string literal. is there a way around for this one? I tried this, but it is not working :(

  • Replacing accented/umlauted characters with their unadorned counterparts in C# [closed]

    - by Andrew Rollings
    Duplicate of 249087 I have a bunch of user generated addresses that may contain characters with diacritic marks. What is the most effective (i.e. generic) way (apart from a straightforward replace) to automatically convert any such characters to their closest English equivalent? E.g. any of àâãäå would become a æ would become the two separate letters ae ç would become c any of èéêë would become e etc. for all possible letter variations (preferably without having to find and encode lookups for each diacritic form of the letter). (Note: I have to pass these addresses on to third party software that is incapable of printing anything other than English characters. I'd rather the software was capable of handling them, but I have no control over that.) EDIT: Never mind... Found the answer [here][2]. It showed up in the "Related" section to the right of the question after I posted, but not in my prior search or as a pre-post suggestion. Hmm. I added the 'diacritics' tag to the other question in any case. EDIT 2: Jeez! Who voted this -1 after I closed it?

  • How can I append text to a start and end of a file as header and footer ?

    - by Morano88
    I'm filling an XML document manually using C# and I need to have <data> as header and </data> as footer for the whole XML file. Is there an easy way to do that ? I know It can be done but I couldn't find a way to do it. Keep in mind that I'm updating the entries so I need to make sure that they always come between the header and the footer. Thanks Example <data> Entry New Entry 1 New Entry 2 </data>

  • Java equivalent of C# @

    - by Simon Rigby
    Hi all, Quick question. Is there an equivalent of @ as applied to strings in Java: For example I can do @"c:\afolder\afile" in C# and have it ignore the escape characters when processing instead of having to do "c:\afolder\aFile". Is there a Java equivalent? hmmm: stackoverflow is escaping on me .. lol. The second example should read: c:(double-backslash)afolder(double-backslash)aFile

  • Changing href atributes with nokogiri and ruby on rails

    - by fool
    Hi, I Have a HTML document with links links, for exemple: <html> <body> <ul> <li><a href="http://someurl.com/etc/etc">teste1</a></li> <li><a href="http://someurl.com/etc/etc">teste2</a></li> <li><a href="http://someurl.com/etc/etc">teste3</a></li> <ul> </body> </html> I want with Ruby on Rails, with nokogiri or some other method, to have a final doc like this: <html> <body> <ul> <li><a href="http://myproxy.com/?url=http://someurl.com/etc/etc">teste1</a></li> <li><a href="http://myproxy.com/?url=http://someurl.com/etc/etc">teste2</a></li> <li><a href="http://myproxy.com/?url=http://someurl.com/etc/etc">teste3</a></li> <ul> </body> </html> What's the best strategy to achieve this?

  • Is it possible to reliably auto-decode user files to Unicode? [C#]

    - by NVRAM
    I have a web application that allows users to upload their content for processing. The processing engine expects UTF8 (and I'm composing XML from multiple users' files), so I need to ensure that I can properly decode the uploaded files. Since I'd be surprised if any of my users knew their files even were encoded, I have very little hope they'd be able to correctly specify the encoding (decoder) to use. And so, my application is left with task of detecting before decoding. This seems like such a universal problem, I'm surprised not to find either a framework capability or general recipe for the solution. Can it be I'm not searching with meaningful search terms? I've implemented BOM-aware detection (http://en.wikipedia.org/wiki/Byte_order_mark) but I'm not sure how often files will be uploaded w/o a BOM to indicate encoding, and this isn't useful for most non-UTF files. My questions boil down to: Is BOM-aware detection sufficient for the vast majority of files? In the case where BOM-detection fails, is it possible to try different decoders and determine if they are "valid"? (My attempts indicate the answer is "no.") Under what circumstances will a "valid" file fail with the C# encoder/decoder framework? Is there a repository anywhere that has a multitude of files with various encodings to use for testing? While I'm specifically asking about C#/.NET, I'd like to know the answer for Java, Python and other languages for the next time I have to do this. So far I've found: A "valid" UTF-16 file with Ctrl-S characters has caused encoding to UTF-8 to throw an exception (Illegal character?) (That was an XML encoding exception.) Decoding a valid UTF-16 file with UTF-8 succeeds but gives text with null characters. Huh? Currently, I only expect UTF-8, UTF-16 and probably ISO-8859-1 files, but I want the solution to be extensible if possible. My existing set of input files isn't nearly broad enough to uncover all the problems that will occur with live files. Although the files I'm trying to decode are "text" I think they are often created w/methods that leave garbage characters in the files. Hence "valid" files may not be "pure". Oh joy. Thanks.

  • How to split a single column values to multiple column values?

    - by Shahsra
    Hi All, I have a problem splitting single column values to multiple column values. For Example: **Name** abcd efgh ijk lmn opq asd j. asdjja asb (asdfas) asd asd and I need the output something like this: first_name last_name abcd efgh ijk opq asd asdjja asb asd asd null The middle name can be omitted (no need for a middle name) The columns are already created and need to insert the data from that single 'Name' column. Thanks a lot, Shahsra

  • php - preg_replace not working when string contains a hashtag

    - by Steven
    I found a function online for turning a url within a string into a clickable link. However, when the url contains a hashtag it doesn't work. eg. http://www.bbc.co.uk/radio1/photos/fearnecotton/5759/1#gallery5759 Here's the part of the function concerned: $ret = preg_replace( "#(^|[\n ])([\w]+?://[\w]+[^ \"\n\r\t< ]*)#", "\\1<a href=\"\\2\" target=\"_blank\">\\2</a>", $ret ); $ret = preg_replace( "#(^|[\n ])((www|ftp)\.[^ \"\t\n\r< ]*)#", "\\1<a href=\"http://\\2\" target=\"_blank\">\\2</a>", $ret ); Any ideas? thanks

  • Regex: Strip HTML attributes except SRC

    - by Ian Silber
    Hi, I'm trying to write a regular expression that will strip all tag attributes except for the SRC attribute. For example: <p id="paragraph" class="green">This is a paragraph with an image <img src="/path/to/image.jpg" width="50" height="75"/></p> Would be returned as: <p>This is a paragraph with an image <img src="/path/to/image.jpg" /></p> I have a regular expression to strip all attributes, but I'm trying to tweak it to leave in src. Here's what I have so far: <?php preg_replace('/<([A-Z][A-Z0-9]*)(\b[^>]*)>/i', '<$1>', '<html><goes><here>'); Using PHP's preg_replace() for this. Thanks! Ian

  • Any clever way to fix 'string or binary data would be truncated' warning with LINQ

    - by Simon_Weaver
    Is there a clever way to determine which field is causing 'string or binary data would be truncated' with LINQ. I've always ended up doing it manually by stepping through a debugger, but with a batch using 'SubmitChanges' I have to change my code to inserting a single row to find the culprit in a batch of rows. Am I missing something or in this day and age do I really have to still use a brute force method to find the problem. Please dont give me advice on avoiding this error in future (unless its something much cleverer than 'validate your data'). The source data is coming from a different system where I dont have full control anyway - plus I want to be lazy. PS. Does SQL Server 2008 actually tell me the field name. Please tell me it does! I'll upgrade!

  • PHP getimagesize with ampersand in string creates errors

    - by RobHardgood
    I'm using the getimagesize function in PHP, and the path string contains an ampersand, which otherwise is fine. The page gives me errors where getimagesize() is called. Looking at the source code, though, I see the ampersand is being passed through as & rather than just & I presume this is causing errors because PHP doesn't need to convert it to the html tag in order to find the path, right? Here is the error: Warning: getimagesize(image.php?name=username&pic=picture) [function.getimagesize]: failed to open stream: No such file or directory

However it doesn't work on my Device, which is set to German. The value is correct but the point, comma or whatever in that double value isn't shown correct. 43.22 on Emulator - 4322 on Device Why is that?
