  • preg_match find multiple partial appearances of a word in a string

    - by Rubytastic
    Any regex gurus around here? its driving me crazy. Say I have this string: "bookstore books Booking" I want to count the number "books" appears in this and return the number. Currently I have this which is not working: $string = "bookstore books Booking"; if (preg_match_all('/\b[A-Z]+books\b/', $string, $matches)) { echo count($matches[0]) . " matches found"; } else { echo "match NOT found"; } On top of this the "books" inside the preg_match_all should become a $var Anyone an idea how to count correctly?

  • Error debugging - Conversion from String to Double

    - by Jamie Taylor
    I'm doing some error debugging trying to get the errors on our website down to a minimum and there seems to be an error that is popping up quite a lot Conversion from string "" to type 'Double' is not valid. I'm unable to replicate this problem but I can see that it is happening. I've been looking through the code in one of the pages and strolled across this Dim varWeek As String If varWeek < 10 Then 'Do something' End If Could this be causing the problem as it is trying to see if a String is less than 10 which is an Integer? As I said before as I am unable to see this error in the first place so changing this to an Integer doesn't change anything on my system. Thanks.

  • Is it a good idea to use MySQL and Neo4j together?

    - by Sanoj
    I will make an application with a lot of similar items (millions), and I would like to store them in a MySQL database, because I would like to do a lot of statistics and search on specific values for specific columns. But at the same time, I will store relations between all the items, that are related in many connected binary-tree-like structures (transitive closure), and relation databases are not good at that kind of structures, so I would like to store all relations in Neo4j which have good performance for this kind of data. My plan is to have all data except the relations in the MySQL database and all relations with item_id stored in the Neo4j database. When I want to lookup a tree, I first search the Neo4j for all the item_id:s in the tree, then I search the MySQL-database for all the specified items in a query that would look like: SELECT * FROM items WHERE item_id = 45 OR item_id = 345435 OR item_id = 343 OR item_id = 78 OR item_id = 4522 OR item_id = 676 OR item_id = 443 OR item_id = 4255 OR item_id = 4345 Is this a good idea, or am I very wrong? I haven't used graph-databases before. Are there any better approaches to my problem? How would the MySQL-query perform in this case?

  • How should I handle multiple links ot the same page with different Query Strings

    - by RandomBen
    In the website I am working on, there is a product page with 8 tabs on it, showing different aspects of the product. There are quick links on other pages within the site that take you to the page and to a specific link specified by a query string. For example the base page would be www.example.com/Product1. And then there are links like this: www.example.com/Product1?tab=CADDrawing www.example.com/Product1?tab=Schematics www.example.com/Product1?tab=Reviews My concern is that Google sees each of these links as a different URL but they aren't and the data on the page is 100% the same. Is there any easy way to make it so Google either knows that www.example.com/Product1 is the base page or doesn't follow the links with Query Strings? I thought about using rel="nofollow" but that seems like it would actually hurt my page ranking. Most of the websites, including Googles on webmaster pages, is unclear. The other option is to add the rel="canonical" to the pages that have a query string but not to the base page. Does that succeed in stopping all of the noisy links?

  • Java - Need help with binary/code string manipulation

    - by ShrimpCrackers
    For a project, I have to convert a binary string into (an array of) bytes and write it out to a file in binary. Say that I have a sentence converted into a code string using a huffman encoding. For example, if the sentence was: "hello" h = 00 e = 01, l = 10, o = 11 Then the string representation would be 0001101011. How would I convert that into a byte? <-- If that question doesn't make sense it's because I know little about bits/byte bitwise shifting and all that has to do with manipulating 1's and 0's.

  • Using function arguments to dynamically generate a query

    - by Varun
    I am working on an issue management system, developed in PHP/MySQL. It requires search functionality, where the user will mention the search parameters and based on these parameters the system will return the result set. To solve this I am trying to write a function and all the user selected parameters are passed as arguments. Based on the arguments I will dynamically generate the query. Sample Query: select * from tickets inner join ticket_assigned_to on tickets.id=ticket_assigned_to.ticket_id where tickets.project_id= in ('') and tickets.status in ('') and ticket_assigned_to.user_id in ('') and tickets.reporter_user_id='' and tickets.operator_user_id in ('') and tickets.due_date between '' and '' and tickets.ts_created between '' and ''; I also need to handle cases where the arguments can be ORed or ANDed in the query. For example: select * from tickets inner join ticket_assigned_to on tickets.id=ticket_assigned_to.ticket_id where tickets.project_id= in ('') and tickets.status in ('') or tickets.due_date = '' or tickets.ts_created between '' and ''; I am also planning to use the same function at other places in the project also. Like to display all the tickets of a user or all tickets created between given dates and so on... How to handle this situation? Should I go with a single function which handles all this or numerous small functions? Need guidance here.

  • How to convert List<int> to string[]?

    - by George Edison
    I need an easy way to convert a List<int> to a string array. I have: var the_list = new List<int>(); the_list.Add(1); the_list.Add(2); the_list.Add(3); string[] the_array = new string[the_list.Count]; for(var i = 0 ; i < the_array.Count; ++i) the_array[i] = the_list[i].ToString(); ...which looks to be very ugly to me. Is there an easier way? Note: I'm looking for an easier way - not necessarily a faster way.

    - by Bibo
    I have these structures: typedef struct dnsQuery { char header[12]; struct dnsQuerySection *querySection; } TdnsQuery; typedef struct dnsQuerySection { unsigned char *name; struct dnsQueryQuestion *question; } TdnsQuerySection; typedef struct dnsQueryQuestion { unsigned short qtype; unsigned short qclass; } TdnsQueryQuestion; and I have dns query in byte array from recvfrom. I am trying to get structure from byte array like this: TdnsQuery* dnsQuery = (TdnsQuery*)buf; When I tried to access qtype like this: printf("%u", dnsQuery->querySection->question.qtype); I get seg fault 11. Can someone help me with these structures? What´s wrong with them? I tried to add structure: typedef struct udpPacket { char header[8]; structr dnsQuery query; } and mapped this structure from byte array but it didn´t help. Can someone help me with these structures? How they should look like for dns query with udp protocol?

  • mod rewrite to remove facebook query string

    - by user905752
    I can't get my query string to work..please help... I have the following url: http://betatest.bracknell-forest.gov.uk/help?fb_action_ids=372043216205703&fb_action_types=og.likes&fb_source=aggregation&fb_aggregation_id=288381481237582 (sorry but the page will be unavailable as it is a test internal domain link) I want the following url: http://betatest.bracknell-forest.gov.uk/help I get a browser message saying 'The system cannot find the file specified.' I know it is because I already have a mod rewrite to remove the .htm from the page name to return clean urls but I don't know what I need to do to accept a clean url and return the page. Here is the mod rewrite code I have: RewriteRule ^/([\w]+)$ /$1.htm [I,L] #Any bare URL will get rewritten to a URL with .htm appended RedirectRule ^/(.+)\.(htm)$ http://betatest.bracknell-forest.gov.uk/$1 [R=301] RewriteCond %{QUERY_STRING} ^fb_action_ids=(.)$ #if the query string contains fb_action_ids RewriteCond %{QUERY_STRING} !="" #if there is a query string RewriteRule ^(.*) $1? [R=301,L] I think it is because I am using R=301 twice but do not know what I need to use as an alternative. If I append .htm from help?fb_action_ids.... to help.htm?fb_action_ids.... this returns the required page fine but I need to return the page name for the non appended url. Many thanks for any help in advance.

  • String Functions in IIS Url Rewritting Module

    - by Nariman
    The IIS URL Rewrite Module ships with 3 built-in functions: * ToLower - returns the input string converted to lower case. * UrlEncode - returns the input string converted to URL-encoded format. This function can be used if the substitution URL in rewrite rule contains special characters (for example non-ASCII or URI-unsafe characters). * UrlDecode - decodes the URL-encoded input string. This function can be used to decode a condition input before matching it against a pattern. The functions can be invoked by using the following syntax: {function_name:any_string} The question is: can this list be extended by introducing a Replace function that's available for changing values within a rewrite rule action or condition?

  • String.Format in javascript?

    - by chobo2
    Hi this is driving me nuts. I believe I asked this exact same question but I can't find it anymore(I used stackoverflow search, google search, manually searched my posts, searched my code). I wanted something that would be like the C# String.Format where you could do something like string format = String.Format("Hi {0}",name); just for javascript of course and one person gave me a simple answer it was not like a jquery plugin or anything but I think you made some json thing or something and it worked and was simple to use. I for the life of me can't find this post.

  • How do I convert a NSString into TIS-620 encoded string

    - by MacPC
    In the apple document, I can see that there's a way to convert from UTF8 string to ASCII string like this NSData *asciiData = [theString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *asciiString = [[NSString alloc] initWithData:asciiData encoding:NSASCIIStringEncoding]; But my app requires a TIS-620 string to post to a site so I try to do the same thing NSData *asciiData = [newPost.header dataUsingEncoding:kCFStringEncodingMacThai allowLossyConversion:YES]; NSString *asciiString = [[NSString alloc] initWithData:asciiData encoding:kCFStringEncodingMacThai]; NSLog(@"%@", asciiString); The output I got is like this ???????????. Does anyone know how to convert the NSString to TIS-620 properly? Thanks so much.

  • C# COM+ component isn't getting the constructor string

    - by Kyle W
    I've created a COM+ component in C# with a strong name, COM Visible, ProgId, etc... I've then registered the assembly with regasm, and imported it into the COM+ Applications in Component Services. It runs just fine, and loads up the DLL, except that the constructor string that is passed in is always empty. The method signature is protected override void Construct(string constructString), and it is being called before the method on the actual component. In the component details in COM+ Applications, the constructor string is checked and a value is entered. Any help is appreciated.

  • more efficient way to pickle a string

    - by gatoatigrado
    The pickle module seems to use string escape characters when pickling; this becomes inefficient e.g. on numpy arrays. Consider the following z = numpy.zeros(1000, numpy.uint8) len(z.dumps()) len(cPickle.dumps(z.dumps())) The lengths are 1133 characters and 4249 characters respectively. z.dumps() reveals something like "\x00\x00" (actual zeros in string), but pickle seems to be using the string's repr() function, yielding "'\x00\x00'" (zeros being ascii zeros). i.e. ("0" in z.dumps() == False) and ("0" in cPickle.dumps(z.dumps()) == True)

  • SQLCe local db in temp- path in connectionstring?

    - by Petr
    Hi, I have SQL Ce db in my app, which is included in my app directory. While debugging its OK, but when published and run with setup.exe, it retrieves "file not found" in temporary directory the app is ran from. I would like to run from standard location, but I dont know how to change it. I am using this string: SqlCeConnection connection = new SqlCeConnection("Data Source=database.sdf;Persist Security Info=False;"); When I run setup.exe, the app never starts, stating that in its temporary directory the db file was not found. When I run app.exe, it works. I do not understand it...:( EDIT: I can see that in the VS project settings, there is connection string and there is "Data Source=|DataDirectory|\Database.sdf" The path should be something like local directory? Thanks!
