• how to create multiple selections in text edit box in qt4?

  - by Ronny

  Qt3.3 used to allow for multiple selections in the QTextEdit widget by calling the setSelection() function and specifying a different selection id (selNum) as the last argument in that function. In Qt4, to create a selection, I do it by creating a QTextCursor object and call the setPosition() or movePosition() methods. I have no problems being able to create a single selection of text. I am, however, unable to find a way to create multiple selections. The methods in Qt4 do not have an argument which allows you to set a selection id, nor can i find any other function in the QTextCursor or QTextEdit which looks like it might allow me to do so. Has this feature been completely removed from Qt4? or has is there a new and different way of doing it? Thanks. Ronny

• web spidering/crawling, can i do it or just search engines?

  - by bboyreason

  i already had a question answered about web-scraping with wget. but as i read a little more, i realize i may be looking for a web-crawling program. particularly the part about web-crawlers being able to get specific data like links or, in my case, products. all of the products on my site have the following naming convention, website.com/uniqueAlphaNumericID.html as far as i know, no dynamic content generation is being used and only one page per one item in the above format. should i just be thinking about: wget website.com | grep *.html or should i be looking into spiders/crawlers?

• Should I go along with my choice of web hosting company or still search?

  - by Devner

  Hi all, I have been searching for a good website hosting company that can offer me all the services that I need for hosting my PHP & MySQL based website. Now this is a community based website and users will be able to upload pictures, etc. The hosting company that I have in mind, currently lets me do everything... let me use mail(), supports CRON jobs, etc. Of course they are charging about $6/month. Now the only problem with this company is that they have a limit of 50,000 files that can exist within the hosting account at any time. This kind of contradicts their frontpage ad of "UNLIMITED SPACE" on their website. Apart from this, I know of no other reason why I should not go with this hosting company. But my issue is that 50,000 file limit is what I cannot live with, once the users increase in significant number and the files they upload, exceed 50,000 in number. Now since this is a dynamic website and also includes sensitive issues like payments, etc. I am not sure if I should go ahead with this company as I am just starting out and then later switch over to a better hosting company which does not limit me with 50,000 files. If I need to switch over once I host with this company, I will need to take backups of all the files located in my account (jpg, zip, etc.), then upload them to the new host. I am not aware of any tools that can help me in this process. Can you please mention if you know any? I can go ahead with the other companies right now, but their cost is double/triple of the current price and they all sport less features than my current choice. If I pay more, then they are ready to accommodate my higher demands. Unfortunately, the company that I am willing to go with now, does NOT have any other higher/better plans that I can switch to. So that's the really really bad part. So my question(s): Since I am starting out with my website and since the scope of users initially is going to be less/small, should I go ahead with the current choice and then once the demand increases, switch over to a better provider? If yes, how can I transfer my database, especially the jpg files, etc. to the new provider? I don't even know the tools required to backup and restore to another host. (I don't like this idea but still..) Should I go ahead and pay more right now and go with better providers (without knowing if the website is going to do really that well) just for saving myself the trouble of having to take a backup of the 50,000 files and upload to a new host from an old host and just start paying double/triple the price without even knowing if I would receive back the returns as I expected? Backup and Restore in such a bulky numbers is something that I have never done before and hence I am stuck here trying to decide what to do. The price per month is also a considerable factor in my decision. All these web hosting companies say one common thing: It is customers responsibility to backup and restore data and they are not liable for any loss. So no matter what hosting company that I would like to go with, they ask me to take backup via FTP so that I can restore them whenever I want (& it seems to be safer to have the files locally with me). Some are providing tools for backup and some are not and I am not sure how much their backup tools can be trusted considering the disclaimers they have. I have never backed-up and restored 50,000 files from one web host to another, so please, all you experienced people out there, leave your comments and let me know your suggestions so that I can decide. I have spent 2 days fighting with myself trying to decide what to do and finally concluded that this is a double-edged sword and I can't arrive at a satisfactory final decision without involving others suggestions. I believe that someone must be out there who may have had such troublesome decision to make. So all your suggestions to help me make my decision are appreciated. Thank you all.

• How do I install the vi text editor ONLY on my Cygwin installation?

  - by gath

  I have managed to install the Cygwin on my Windows Vista machine. I installed using the default settings. When I try to do vi in the Bash shell, Bash tells me command not found. I believe I need to install the Cygwin editors package which include the vi editor. The nightmare is every time I run the Cygwin setup and select ONLY the editors package and specifically the Vim and select install, Cygwin setup tries to install all other packages, very frustrating!! Is there an easier way of installing just a single package using the Cygwin setup utility?

• Excel - Disable AutoFormatting on Import

  - by Philip Wales

  How can I stop Microsoft Excel from auto formatting data when imported from a text file? Specifically, I want it to treat all of the values as text. I am auditing insurance data in excel before it is uploaded to the new database. The files come to me as tab delimited text files. When loaded, Excel auto-formats the data causing leading 0's on Zip Codes, Routing Numbers and other codes, to be chopped off. I don't have the patience to reformat all of the columns as text and guess how many zeros need to be replaced. Nor do I want to click through the import wizard an specify that each column is text. Ideally I just want to turn off Excel's Auto-Formatting completely, and just edit every cell as it were plain text. I don't do any formula's or charts, just grid plain text editing.

• JavaScript - Efficiently find all elements containing one of a large set of strings

  - by noah

  I have a set of strings and I need to find all all of the occurrences in an HTML document. Where the string occurs is important because I need to handle each case differently: String is all or part of an attribute. e.g., the string is foo: <input value="foo"> - Add class ATTR to the element. String is the full text of an element. e.g., <button>foo</button> - Add class TEXT to the element. String is inline in the text of an element. e.g., <p>I love foo</p> - Wrap the text in a span tag with class TEXT. Also, I need to match the longest string first. e.g., if I have foo and foobar, then <p>I love foobar</p> should become <p>I love <span class="TEXT">foobar</span></p>, not <p>I love <span class="TEXT">foo</span>bar</p>. The inline text is easy enough: Sort the strings descending by length and find and replace each in document.body.innerHTML with <span class="TEXT">$1</span>, although I'm not sure if that is the most efficient way to go. For the attributes, I can do something like this: sortedStrings.each(function(it) { document.body.innerHTML.replace(new RegExp('(\S+?)="[^"]*'+escapeRegExChars(it)+'[^"]*"','g'),function(s,attr) { $('[+attr+'*='+it+']').addClass('ATTR'); }); }); Again, that seems inefficient. Lastly, for the full text elements, a depth first search of the document that compares the innerHTML to each string will work, but for a large number of strings, it seems very inefficient. Any answer that offers performance improvements gets an upvote :)

• How do you search a document for a string in c++?

  - by Jeff

  Here's my code so far: #include<iostream> #include<string> #include<fstream> using namespace std; int main() { int count = 0; string fileName; string keyWord; string word; cout << "Please make sure the document is in the same file as the program, thank you!" << endl << "Please input document name: " ; getline(cin, fileName); cout << endl; cout << "Please input the word you'd like to search for: " << endl; cin >> keyWord; cout << endl; ifstream infile(fileName.c_str()); while(infile.is_open()) { getline(cin,word); if(word == keyWord) { cout << word << endl; count++; } if(infile.eof()) { infile.close(); } } cout << count; } I'm not sure how to go to the next word, currently this infinite loops...any recommendation? Also...how do I tell it to print out the line that that word was on? Thanks in advance!

• How can I generate a random human-readable colour from a seed? C#

  - by SLC

  Got a logfile, and it has all kinds of text in it. Currently it is just displayed as one colour, and each entry says something like: Log from section 1: Some text here Log from section 125: Some text here Log from section 17: Some text here Log from section 1: Some text here Log from section 125: Some text here Log from section 1: Some text here Log from section 17: Some text here Now the logfile is displayed in real time, and it would be nice to make the rows with the same section number the same colour. However there could be potentially quite a large range of numbers. What I want to do is create a method that will take a number, and randomly generate a unique colour. The colour must be readable against a black background though, so #000000 is no good, nor is #101010 or anything too dark to read. Ideally two similar numbers will not produce the same colour because in the above examples, the numbers 1 and 17 might be too similar, and some numbers might be in the 10,000 range. Any ideas on this?

• How to Get Dictionary<int, string> from Linq to XML Anonymous Object?

  - by DaveDev

  Currently I'm getting a list of HeaderColumns from the following XML snippet: <HeaderColumns> <column performanceId="12" text="Over last month %" /> <column performanceId="13" text="Over last 3 months %" /> <column performanceId="16" text="1 Year %" /> <column performanceId="18" text="3 Years % p.a." /> <column performanceId="20" text="5 Years % p.a." /> <column performanceId="22" text="10 Years % p.a." /> </HeaderColumns> from which I create an object as follows: (admitedly similar to an earlier question!) var performancePanels = new { Panels = (from panel in doc.Elements("PerformancePanel") select new { HeaderColumns = (from column in panel.Elements("HeaderColumns").Elements("column") select new { PerformanceId = (int)column.Attribute("performanceId"), Text = (string)column.Attribute("text") }).ToList(), }).ToList() }; I'd like if HeaderColumns was a Dictionary() so later I extract the values from the anonymous object like follows: Dictionary<int, string> myHeaders = new Dictionary<int, string>(); foreach (var column in performancePanels.Panels[0].HeaderColumns) { myHeaders.Add(column.PerformanceId, column.Text); } I thought I could achieve this with the Linq to XML with something similar to this HeaderColumns = (from column in panel.Elements("HeaderColumns").Elements("column") select new Dictionary<int, string>() { (int)column.Attribute("performanceId"), (string)column.Attribute("text") }).ToDictionary<int,string>(), but this doesn't work because ToDictionary() needs a Func parameter and I don't know what that is / how to implement it, and the code's probably wrong anyway! Could somebody please suggest how I can achieve the result I need? Thanks.

• What sort of object is this and how to use it?

  - by Gary

  What would be the correct name for this type of array? There are 3 main sections and 4 sub-parts consisting of "issuedTime" "text" "url" and "validToTime", how do you start to convert this to an object? If there was only 1 main section, it would be fairly simple to do however with 3 main parts and no identification for each main section has me scratching my head as where to start. Any advise appreciated. [{ "issuedTime":"7:13pm Sunday 13 June 2010", "text":"\nAmended 7:10pm.\n\nText text and more text\n", "url":"\/folder\/fc\/name.png", "validToTime":"12:00am Monday 14 June 2010" },{ "issuedTime":"8:33pm Sunday 13 June 2010", "text":"\nText and more text.\n", "url":"\/folder\/fc\/name.png", "validToTime":"12:00pm Monday 14 June 2010" },{ "issuedTime":"10:40am Sunday 13 June 2010", "text":"\nAnd even more text.", "url":"\/folder\/fc\/name.png", "validToTime":"12:00am Tuesday 15 June 2010" } ]

• Can I test for the end of the content of a text/plain file with Selenium or javascript?

  - by fool4jesus

  I have a page that results in a text/plain file being displayed in the browser that looks like this: ... Admin Site Administration 2010-04-21 22:26:34 [email protected] Test Site Bob Smith 2010-04-21 22:27:09 [email protected] Admin Site Administration 2010-04-21 22:29:26 [email protected] I am trying to write a Selenium test against this that verifies the last line of the file has "[email protected]" at the end. How would you do this? I can't depend on the date/time as this is a login report that is constantly getting updated - all I want is to ensure that the last line ends with that email address. And I can't figure out how to do it using Selenium expressions, DOM, or XPath.

• using C# how to convert iso8859-1 encoded text files that contain Latin-1 accented characters to utf

  - by Tim

  I am being sent text files saved in iso88591-1 format that contain accented characters from the Latin-1 range (as well as normal ASCII a-z etc). How to convert these files to utf-8 using C# so that the single-byte accented characters in iso8859-1 become valid utf-8 characters? I have tried to use a StreamReader with ASCIIEncoding, and then converting the ascii string to UTF-8 by instantiating an ascii encoding and a utf8 encoding and then using Encoding.Convert(ascii, utf8, ascii.GetBytes( asciiString) ) — but the accented characters are being rendered as question marks. What step am I missing? Thanks

• Loop through custom template hooking thing

  Hi, I am building a template system for emailing people that currently works in the format of: $array['key1'] = "text; $array['key2'] = "more text"; <!--key1--> // replaced with *text* <!--key2--> // replaced with *more text* For this particular project I have a nested array with this kind of structure: $array['object1']['nest1']['key1'] = "text"; $array['object2']['next1']['key1'] = "more text"; <!--[object1][nest1][key1]--> // replaced with *text* <!--[object2][nest1][key1]--> // replaced with *more text* What would be the best way to do this in PHP? I thought I could loop through the arrays but then I just lost my trail of thought and got lost in what I was doing! All help would be appreciated!! Thanks

• Help! Obj-C/Iphone programming: extracting string from html text and reading off line by line

  hihi, I have this html text response from a particular website: <tr><td valign="top"><img src="/icons/image2.gif" alt="[IMG]"></td><td><a href="crsdsdfs2221.jpg">crash-2221.jpg</a></td><td align="right">14-Jun-2010 14:29 Notice for every line, there is this href=".__", which is an image file with random name and random format. I would like to extract that string within the inverted commas out so that i can append it into a URL path and download the image. I've been looking through this documentation from apple: http://developer.apple.com/mac/library/documentation/cocoa/conceptual/strings/Articles/SearchingStrings.html#//apple_ref/doc/uid/20000149-CJBBGBAI on String programming but couldn't find one that fits my bill.

• Possible to load entries into hosts.deny from text file?

  - by Tar

  I have around 96 million IP addresses that I have collected and routinely validate to be VPN providers, proxies, etc. I want these blocked. Currently, I am including the list formatted like deny ip; in nginx and that works perfectly. I want to use this list on another server, but nginx isn't an option, and I don't trust apache to handle this without slowing down. Is there a way to load this list into hosts deny via some command like aclexec or something? Are there other alternatives like setting up a DNSBL or using hosts.deny in conjunction with one?

• Keeping User-Input UITextVIew Content Constrained to Its Own Frame

  - by siglesias

  Trying to create a large textbox of fixed size. This problem is very similar to the 140 character constraint problem, but instead of stopping typing at 140 characters, I want to stop typing when the edge of the textView's frame is reached, instead of extending below into the abyss. Here is what I've got for the delegate method. Seems to always be off by a little bit. Any thoughts? - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { BOOL edgeBump = NO; CGSize constraint = textView.frame.size; CGSize size = [[textView.text stringByAppendingString:text] sizeWithFont:textView.font constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap]; CGFloat height = size.height; if (height > textView.frame.size.height) { edgeBump = YES; } if([text isEqualToString:@"\b"]){ return YES; } else if(edgeBump){ NSLog(@"EDGEBUMP!"); return NO; } return YES; } EDIT: As per Max's suggestion below, here is the code that works: - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { CGSize constraint = textView.frame.size; NSString *whatWasThereBefore = textView.text; textView.text = [textView.text stringByReplacingCharactersInRange:range withString:text]; if (textView.contentSize.height >= constraint.height) { textView.text = whatWasThereBefore; } return NO; }
