  • keep HTMLformat after replace some text (using PHP and JS)

    - by Sadi
    I would like modify HTML like I am <b>Sadi, novice</b> programmer. to I am <b>Sadi, learner</b> programmer. To do it I will search using a string "novice programmer". How can I do it please? Any idea? Thank you Sadi More clarification: I get some nice reply with possible solution. But please keep posting if you have any idea in mind. I would like to more clarify the problem just in case anyone missed it. Main post shows the problem as an example scenario. 1) Now the problem is find and replace some string without considering the tags. The tags may shows up within a single word. String may contain multiple word. Tag only appear in the content string or the document. The search phrase never contain any tags. We can easily remove all tags and do some text operation. But here the another problem shows up. 2) The tags must be preserve, even after replacing the text. That is what the example shows. Thank you Again for helping

  • UITableView via NSFetchedResultsControllerDelegate, select first record by default?

    - by deafgreatdane
    I have a UITableView that gets populated from CoreData via a controller that implements NSFetchedResultsControllerDelegate. How can I have it automatically select the first row (and fire the tableView:didSelectRowAtIndexPath message)? The tableview is used for a variety of predicate queries, so I'm suspicious of solutions that work on the UIViewController lifecycle (viewDidLoad, etc), but I'm new to the platform, so I'm open. I've tried a variety of things, but I'm not sure where in the call stack to put it. I've tried calling cell.selected = true inside tableView:cellForRowAtIndex: method, but that just ends up turning the cell black (and doesn't fire the selected callback method) A tagent question, with all the delegating and core data protocols, does it imply asynchronous data fetch (multiple threads)? Or is the NSFetchedResultsController calling all its related methods in the same thread? Maybe I'm just scared that if it is async, there would be race conditions that would be tough to troubleshoot later.

  • Generate EF4 POCO classes first time only

    - by Jaxidian
    The problem I'm having is, using the POCO templates, generating my POCO classes the first time only and not overwriting them when the templates are re-ran. I know this sounds hokey and the reason is that I'm actually changing these templates and trying to generate metadata classes rather than the actual POCO classes, but these metadata classes will be hand-edited and I want to keep those edits in the future but still regenerate a certain amount of it. I have it all working exactly as I want except for the regeneration of the files. I have looked into T4 and it seems that there is a flag to do just this (see the Output.PreserveExistingFile property) but I don't understand where/how to set this flag. If you can tell me where/how to set this in the default POCO templates, then I think that's all I really need. Thanks!! :-)

  • C# Desktop Application "Encounters an error and has to exit" on first run of the day

    - by Sreedevi J
    Hello, It seems I tend to attract strange issues. This time, I have written a C# application, and handled most of the exceptions I can find. The problem is, when I run the installed/bundled version on any PC for the first time in a day (after the PC has been shut down and started after a while) it comes across some error and has to shutdown the application (even though the try-catch block surrounding the Main() does not fire). The application does not throw the same error on subsequent runs. I added an #if(!DEBUG) ... #else ... #endif surrounding the Main() code. Can anyone help me? Thanks!

  • GWT removeHandler on first event notification

    - by Keith
    I want to remove a GWT event handler the first time I receive an event. I also want to avoid polluting my class with tracking registration objects that aren't really necessary. I currently have it coded as: final HandlerRegistration[] registrationRef = new HandlerRegistration[1]; registrationRef[0] = dialog.addFooHandler(new FooHandler() { public void onFoo(FooEvent event) { HandlerRegistration removeMe = registrationRef[0]; if(removeMe != null) { removeMe.removeHandler(); } // do stuff here } }); but the use of registrationRef makes the code less readable. Is there a better way to do this without adding variables to my class?

  • twython search api rate limit: Header information will not be updated

    - by user2715478
    I want to handle the Search-API rate limit of 180 requests / 15 minutes. The first solution I came up with was to check the remaining requests in the header and wait 900 seconds. See the following snippet: results = search_interface.cursor(search_interface.search, q=k, lang=lang, result_type=result_mode) while True: try: tweet = next(results) if limit_reached(search_interface): sleep(900) self.writer(tweet) def limit_reached(search_interface): remaining_rate = int(search_interface.get_lastfunction_header('X-Rate-Limit-Remaining')) return remaining_rate <= 2 But it seems, that the header information are not reseted to 180 after it reached the two remaining requests. The second solution I came up with was to handle the twython exception for rate limitation and wait the remaining amount of time: results = search_interface.cursor(search_interface.search, q=k, lang=lang, result_type=result_mode) while True: try: tweet = next(results) self.writer(tweet) except TwythonError as inst: logger.error(inst.msg) wait_for_reset(search_interface) continue except StopIteration: break def wait_for_reset(search_interface): reset_timestamp = int(search_interface.get_lastfunction_header('X-Rate-Limit-Reset')) now_timestamp = datetime.now().timestamp() seconds_offset = 10 t = reset_timestamp - now_timestamp + seconds_offset logger.info('Waiting {0} seconds for Twitter rate limit reset.'.format(t)) sleep(t) But with this solution I receive this message INFO: Resetting dropped connection: api.twitter.com" and the loop will not continue with the last element of the generator. Have somebody faced the same problems? Regards.

  • read first 1kb of a blob from oracle

    - by Angus
    Hi, I wish to extract just the first 1024 bytes of a stored blob and not the whole file. The reason for this is I want to just extract the metadata from a file as quickly as possible without having to select the whole blob. I understand the following: select dbms_lob.substr(file_blob, 16,1) from file_upload where file_upload_id=504; which returns it as hex. How may I do this so it returns it in binary data without selecting the whole blob? Thanks in advance.

  • SQL Server search filter and order by performance issues

    - by John Leidegren
    We have a table value function that returns a list of people you may access, and we have a relation between a search and a person called search result. What we want to do is that wan't to select all people from the search and present them. The query looks like this SELECT qm.PersonID, p.FullName FROM QueryMembership qm INNER JOIN dbo.GetPersonAccess(1) ON GetPersonAccess.PersonID = qm.PersonID INNER JOIN Person p ON p.PersonID = qm.PersonID WHERE qm.QueryID = 1234 There are only 25 rows with QueryID=1234 but there are almost 5 million rows total in the QueryMembership table. The person table has about 40K people in it. QueryID is not a PK, but it is an index. The query plan tells me 97% of the total cost is spent doing "Key Lookup" witht the seek predicate. QueryMembershipID = Scalar Operator (QueryMembership.QueryMembershipID as QM.QueryMembershipID) Why is the PK in there when it's not used in the query at all? and why is it taking so long time? The number of people total 25, with the index, this should be a table scan for all the QueryMembership rows that have QueryID=1234 and then a JOIN on the 25 people that exists in the table value function. Which btw only have to be evaluated once and completes in less than 1 second.

  • Load first page on splashscreen using phonegap on android

    - by Syg
    Hi i'm using phonegap in conjunction with Jquery mobile. I'm trying to immediately fetch the main page, while showing the user a splashscreen. In PhoneGap for Android i'm using this super.setIntegerProperty("splashscreen", R.drawable.splash); super.loadUrl("file:///android_asset/www/index.html", 2000); While this loads the splash, it also delays the loading of index.html. It it possible to start fetching it right away? Also, if not with phonegap, has anybody done this using JQM instead of phonegap? UPDATE: After using it with a slower loading first page (doing a json request) it kinda looks like the splash screens shows for a longer period of time, so this appears to be the default behavior

  • Tell me SQL Server Full-Text searcher is crazy, not me.

    - by Ian Boyd
    i have some customers with a particular address that the user is searching for: 123 generic way There are 5 rows in the database that match: ResidentialAddress1 ============================= 123 GENERIC WAY 123 GENERIC WAY 123 GENERIC WAY 123 GENERIC WAY 123 GENERIC WAY i run a FT query to look for these rows. i'll show you each step as i add more criteria to the search: SELECT ResidentialAddress1 FROM Patrons WHERE CONTAINS(Patrons.ResidentialAddress1, '"123*"') ResidentialAddress1 ========================= 123 MAPLE STREET 12345 TEST 123 MINE STREET 123 GENERIC WAY 123 FAKE STREET ... (30 row(s) affected) Okay, so far so good, now adding the word "generic": SELECT ResidentialAddress1 FROM Patrons WHERE CONTAINS(Patrons.ResidentialAddress1, '"123*"') AND CONTAINS(Patrons.ResidentialAddress1, '"generic*"') ResidentialAddress1 ============================= 123 GENERIC WAY 123 GENERIC WAY 123 GENERIC WAY 123 GENERIC WAY 123 GENERIC WAY (5 row(s) affected) Excellent. And now i'l add the final keyword that the user wants to make sure exists: SELECT ResidentialAddress1 FROM Patrons WHERE CONTAINS(Patrons.ResidentialAddress1, '"123*"') AND CONTAINS(Patrons.ResidentialAddress1, '"generic*"') AND CONTAINS(Patrons.ResidentialAddress1, '"way*"') ResidentialAddress1 ------------------------------ (0 row(s) affected) Huh? No rows? What if i query for just "way*": SELECT ResidentialAddress1 FROM Patrons WHERE CONTAINS(Patrons.ResidentialAddress1, '"way*"') ResidentialAddress1 ------------------------------ (0 row(s) affected) At first i thought that perhaps it's because of the *, and it's requiring that the root way have more characters after it. But that's not true: Searching for "123*" matches "123" Searching for "generic*" matches "generic" Books online says, The asterisk matches zero, one, or more characters What if i remove the * just for s&g: SELECT ResidentialAddress1 FROM Patrons WHERE CONTAINS(Patrons.ResidentialAddress1, '"way"') Server: Msg 7619, Level 16, State 1, Line 1 A clause of the query contained only ignored words. So one might think that you are just not allowed to even search for way, either alone, or as a root. But this isn't true either: SELECT * FROM Patrons WHERE CONTAINS(Patrons.*, '"way*"') AccountNumber FirstName Lastname ------------- --------- -------- 33589 JOHN WAYNE So sum up, the user is searching for rows that contain all the words: 123 generic way Which i, correctly, translate into the WHERE clauses: SELECT * FROM Patrons WHERE CONTAINS(Patrons.*, '"123*"') AND CONTAINS(Patrons.*, '"generic*"') AND CONTAINS(Patrons.*, '"way*"') which returns no rows. Tell me this just isn't going to work, that it's not my fault, and SQL Server is crazy. Note: i've emptied the FT index and rebuilt it.

  • Advanced SQL query with lots of joins

    - by lund.mikkel
    Hey fellow programmers Okay, first let me say that this is a hard one. I know the presentation may be a little long. But I how you'll bare with me and help me through anyway :D So I'm developing on an advanced search for bicycles. I've got a lot of tables I need to join to find all, let's say, red and brown bikes. One bike may come in more then one color! I've made this query for now: SELECT DISTINCT p.products_id, #simple product id products_name, #product name products_attributes_id, #color id pov.products_options_values_name #color name FROM products p LEFT JOIN products_description pd ON p.products_id = pd.products_id INNER JOIN products_attributes pa ON pa.products_id = p.products_id LEFT JOIN products_options_values pov ON pov.products_options_values_id = pa.options_values_id LEFT JOIN products_options_search pos ON pov.products_options_values_id = pos.products_options_values_id WHERE pos.products_options_search_id = 4 #code for red OR pos.products_options_search_id = 5 #code for brown My first concern is the many joins. The Products table mainly holds product id and it's image and the Products Description table holds more descriptive info such as name (and product ID of course). I then have the Products Options Values table which holds all the colors and their IDs. Products Options Search is containing the color IDs along with a color group ID (products_options_search_id). Red has the color group code 4 (brown is 5). The products and colors have a many-to-many relationship managed inside Products Attributes. So my question is first of all: Is it okay to make so many joins? Is i hurting the performance? Second: If a bike comes in both red and brown, it'll show up twice even though I use SELECT DISTINCT. Think this is because of the INNER JOIN. Is this possible to avoid and do I have to remove the doubles in my PHP code? Third: Bikes can be double colored (i.e. black and blue). This means that there are two rows for that bike. One where it says the color is black and one where is says its blue. (See second question). But if I replace the OR in the WHERE clause it removes both rows, because none of them fulfill the conditions - only the product. What is the workaround for that? I really hope you will and can help me. I'm a little desperate right now :D Regards Mikkel Lund

    - by Marc
    Hi! I'm totally new in C, and I'm trying to do a little application that searches a string into a file, my problem is that I need to open a big file (more than 1GB) with just one line inside and fgets return me the entire file (I'm doing test with a 10KB file). actually this is my code: #include <stdio.h> #include <string.h> int main(int argc, char *argv[]) { char *search = argv[argc-1]; int retro = strlen(search); int pun = 0; int sortida; int limit = 10; char ara[20]; FILE *fp; if ((fp = fopen ("SEARCHFILE", "r")) == NULL){ sortida = -1; exit (1); } while(!feof(fp)){ if (fgets(ara, 20, fp) == NULL){ break; } //this must be a 20 bytes line, but it gets the entyre 10Kb file printf("%s",ara); } sortida = 1; if(fclose(fp) != 0){ sortida = -2; exit (1); } return 0; } What can I do to find an string into a file? I'v tried with GREP but it don't helps, because it returns the position:ENTIRE_STRING. I'm open to ideas. Thanks in advance!

  • Add entry to list and remove first one in Python

    I have a list of about 40 entries. And I frequently want to append an item to the start of the list (with id 0) and want to delete the last entry (with id 40) of the list. how do i do this the best? like: (example with 5 entries) [0] = "herp" [1] = "derp" [2] = "blah" [3] = "what" [4] = "da..." after adding "wuggah" and deleting last it should be like: [0] = "wuggah" [1] = "herp" [2] = "derp" [3] = "blah" [4] = "what" or appending one and deleting first. And I don't want to end up manually moving them one after another all of the entries to the next id.

  • how can a Win32 App plugin load its DLL in its own directory

    - by Jean-Denis Muys
    My code is a plugin for a specific Application, written in C++ using Visual Studio 8. It uses two DLL from an external provider. Unfortunately, my plugin fails to start because the DLLs are not found (I put them in the same directory as the plugin itself). When I manually move or copy the DLLs to the host application directory, then the plugin loads fine. This moving was deemed unacceptably cumbersome for the end user, and I am looking for a way for my plugin to load its DLLs transparently. What can I do? Relevant details: the host Application plugins are located in a directory mandated by the host application. That directory is not in the DLL search path and I don't control it. The plugin is itself packaged as a subdirectory of the plugin directory, holding the plugin code itself, but also any resource associated with the plugin (eg images, configuration files…). I control what's inside that subdirectory, called a "bundle", but not where it's located. the common plugin installation idiom for that App is for the end user to copy the plugin bundle to the plugin directory. This plugin is a port from the Macintosh version of the plugin. On the Mac there is no issue because each binary contains its own dynamic library search path, which I set as I needed to for my plugin binary. To set that on the Mac simply involves a project setting in the Xcode IDE. This is why I would hope for something similar in Visual Studio, but I could not find anything relevant. Moreover, Visual Studio's help was anything but, and neither was Google. A possible workaround would be for my code to explicitly tell Windows where to find the DLL, but I don't know how, and in any case, since my code is not even started, it hasn't got the opportunity to do so. As a Mac developer, I realize that I may be asking for something very elementary. If such is the case, I apologize, but I have run out of hair to pull out.

  • Operating System for first production windows server code?

    - by Unkwntech
    I'm getting ready to purchase a server for me to deploy my first windows based (C# .NET) application but I'm not familiar with using windows for hosted applications. I have the choice of the following versions of windows: Windows Server 2003 Windows Server 2003 Web Windows Server 2003 Enterprise Windows Server 2008 Windows Server 2008 Web Windows Server 2008 Enterprise Would one of these be better for deploying a C# .NET application? EDIT: There will be 3 applications deployed but each will basically be the same, they will be services that are driven from data being brought in from a website that will likely run on the same server. http://www.microsoft.com/windowsserver2008/en/us/compare-roles.aspx

  • How to select only the first rows for each unique value of a column

    Let's say I have a table of customer addresses: CName | AddressLine ------------------------------- John Smith | 123 Nowheresville Jane Doe | 456 Evergreen Terrace John Smith | 999 Somewhereelse Joe Bloggs | 1 Second Ave In the table, one customer like John Smith can have multiple addresses. I need the select query for this table to return only first row found where there are duplicates in 'CName'. For this table it should return all rows except the 3rd (or 1st - any of those two addresses are okay but only one can be returned). Is there a keyword I can add to the SELECT query to filter based on whether the server has already seen the column value before?

  • Querying datatable to get rows with a certain value in the first column

    I am currently using the code below and am wondering if it would be possible to query based on an entry value. At the moment it returns the number of rows that have been defined. var q = sqlData.AsEnumerable().Take(2); This data comes in from a database and is imputed into the table but at the moment it only returns database data into the datatable and allows me to select the first two rows and I was wondering if I can query the data table so that I can get the rows that I require based on an index in the actual table itself (e.g. in the table I find five rows and query this information out).

  • How to select the first property with unknown name from JSON and how to select first item from array

  • Matching First Alphanumeric Character skipping (The |An? )

    - by TheLizardKing
    I have a list of artists, albums and tracks that I want to sort using the first letter of their respective name. The issue arrives when I want to ignore "The ", "A ", "An " and other various non-alphanumeric characters (Talking to you "Weird Al" Yankovic and [dialog]). Django has a nice start '^(An?|The) +' but I want to ignore those and a few others of my choice. I am doing this in Django, using a MySQL db with utf8_bin collation. EDIT Well my fault for not mentioning this but the database I am accessing is pretty much ready only. It's created and maintained by Amarok and I can't alter it without a whole mess of issues. That being said the artist table has The Chemical Brothers listed as The Chemical Brothers so I think I am stuck here. It probably will be slow but that's not so much of a concern for me as it's a personal project.

  • SQL Server full text query across multiple tables - why so slow?

    - by Mikey Cee
    Hi. I'm trying to understand the performance of an SQL Server 2008 full-text query I am constructing. The following query, using a full-text index, returns the correct results immediately: SELECT O.ID, O.Name FROM dbo.EventOccurrence O WHERE FREETEXT(O.Name, 'query') ie, all EventOccurrences with the word 'query' in their name. And the following query, using a full-text index from a different table, also returns straight away: SELECT V.ID, V.Name FROM dbo.Venue V WHERE FREETEXT(V.Name, 'query') ie. all Venues with the word 'query' in their name. But if I try to join the tables and do both full-text queries at once, it 12 seconds to return: SELECT O.ID, O.Name FROM dbo.EventOccurrence O INNER JOIN dbo.Event E ON O.EventID = E.ID INNER JOIN dbo.Venue V ON E.VenueID = V.ID WHERE FREETEXT(E.Name, 'search') OR FREETEXT(V.Name, 'search') Here is the execution plan: http://uploadpad.com/files/query.PNG From my reading, I didn't think it was even possible to make a free text query across multiple tables in this way, so I'm not sure I am understanding this correctly. Note that if I remove the WHERE clause from this last query then it returns all results within a second, so it's definitely the full-text that is causing the issue here. Can someone explain (i) why this is so slow and (ii) if this is even supported / if I am even understanding this correctly. Thanks in advance for your help.
