  • How to avoid truncation of text with UITableViewCellStyleValue2

    - by Regan
    I use this code to make my UITableViewCells cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:CellIdentifier] autorelease]; If you're unfamiliar with UITableViewCellStyleValue2, the main text is shown, and then the detail text is shown after it, generally in a different color. However, when I do this, my main text is truncated, if it is longer than a short word. I want to force it to not truncate the main text and show the entire main text, and then the detail text after it. How can I do that?

  • How to truncate milliseconds off of a .NET DateTime

    - by Jeff Putz
    I'm trying to compare a time stamp from an incoming request to a database stored value. SQL Server of course keeps some precision of milliseconds on the time, and when read into a .NET DateTime, it includes those milliseconds. The incoming request to the system, however, does not offer that precision, so I need to simply drop the milliseconds. I feel like I'm missing something obvious, but I haven't found an elegant way to do it (C#).

  • JPA - How to truncate tables between unit tests

    - by Theo
    I want to cleanup the database after every test case without rolling back the transaction. I have tried DBUnit's DatabaseOperation.DELETE_ALL, but it does not work if a deletion violates a foreign key constraint. I know that I can disable foreign key checks, but that would also disable the checks for the tests (which I want to prevent). I'm using JUnit 4, JPA 2.0 (Eclipselink), and Derby's in-memory database. Any ideas? Thanks, Theo

  • Truncate a UTF-8 string to fit a given byte count in PHP

    - by fsb
    Say we have a UTF-8 string $s and we need to shorten it so it can be stored in N bytes. Blindly truncating it to N bytes could mess it up. But decoding it to find the character boundaries is a drag. Is there a tidy way? [Edit 20100414] In addition to S.Mark’s answer: mb_strcut(), I recently found another function to do the job: grapheme_extract($s, $n, GRAPHEME_EXTR_MAXBYTES); from the intl extension. Since intl is an ICU wrapper, I have a lot of confidence in it.

  • Bind9 as a caching resolver fails with mismatch ID on localhost but not external IP

    - by argibbs
    I'm running Ubuntu 12.04 LTS on a machine on my private network. I have bind9 installed (v9.8.1-P1) via aptitude, so it appears to have put all the bits in the right places and the service starts automatically. I plan on adding some zones later, but first I'm just trying to get it working as a caching resolver. I installed bind, configured it, and starting using it. Initially I thought it was working ok, but then I found some sites weren't being resolved. I've pinned it down to being linked to the size of the result and bind failing-over to TCP mode. So: I'm trying to find out why bind is failing when I query for domain info and the result is 512 bytes (causing a truncation and retry on TCP). Specifically it fails with ID mismatches if I point dig at localhost, but works when I query the machine's own IP (192.168.0.2). This appears to be backwards to the problem that most people have when using bind (fails on external ip, works on localhost). If I do dig @localhost google.com (which has a response of <512 bytes) then it works; I get no warnings, and plenty of output. $ dig @localhost google.com ; <<>> DiG 9.8.1-P1 <<>> @localhost google.com [snip lots of output] ;; Query time: 39 msec ;; SERVER: 127.0.0.1#53(127.0.0.1) ;; WHEN: Thu Oct 17 23:08:34 2013 ;; MSG SIZE rcvd: 495 If I do dig @localhost play.google.com (which has a larger response) then I get back something like: $ dig @localhost play.google.com ;; Truncated, retrying in TCP mode. ;; ERROR: ID mismatch: expected ID 3696, got 27130 This seems to be standard, documented behaviour - when the UDP response is large (here 'large' == 512 bytes) it falls back to TCP. The ID mismatch is not expected though. If I do dig @192.168.0.2 play.google.com then I still get the warning about using TCP mode, but it otherwise works $ dig @192.168.0.2 play.google.com ;; Truncated, retrying in TCP mode. ; <<>> DiG 9.8.1-P1 <<>> @192.168.0.2 play.google.com [snip most of the output] ;; Query time: 5 msec ;; SERVER: 192.168.0.2#53(192.168.0.2) ;; WHEN: Thu Oct 17 23:05:55 2013 ;; MSG SIZE rcvd: 521 At the moment I've not set up any zones in my local instance, so it's just acting as a caching resolver. My options config is pretty much unchanged from standard, I've got the following set: options { directory "/var/cache/bind"; allow-query { 192.168/16; 127.0.0.1; }; forwarders { 8.8.8.8; 8.8.4.4; }; dnssec-validation auto; edns-udp-size 4096 ; allow-transfer { any; }; auth-nxdomain no; # conform to RFC1035 listen-on-v6 { any; }; }; And my /etc/resolv.conf is just nameserver 127.0.0.1 search .local The problem definitely seems linked to the failover to TCP mode: if I do dig +bufsize=4096 @localhost play.google.com then it works; no warning about failover to TCP, no ID mismatch, and a standard looking result. To be honest, if there was a way to force bind to use a much larger UDP buffer, that'd probably be good enough for me, but all I've been able to find mention of is max-udp-size 4096 and that doesn't change the behaviour in any way. I've also tried setting edns-udp-size 512 in case the problem is some weird EDNS issue with my router (which seems unlikely since the +bufsize=4096 flag works fine). I've also tried dig +trace @localhost play.google.com; this works. No truncation/TCP warning, and a full result. I've also tried changing the servers used in the forwarder (e.g. to OpenDNS), but that makes no difference. There's one last data point: if I repetitively do dig @localhost play.google.com I don't always get an ID mismatch, but sometimes a REFUSED error. I'm much more likely to get a REFUSED error if I dig the non-localhost IP (192.168.0.2) first: $ dig @localhost play.google.com ;; Truncated, retrying in TCP mode. ; <<>> DiG 9.8.1-P1 <<>> @localhost play.google.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 35104 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;play.google.com.

  • Truncating a file while it's being used (Linux)

    - by Hobo
    I have a process that's writing a lot of data to stdout, which I'm redirecting to a log file. I'd like to limit the size of the file by occasionally copying the current file to a new name and truncating it. My usual techniques of truncating a file, like cp /dev/null file don't work, presumably because the process is using it. Is there some way I can truncate the file? Or delete it and somehow associate the process' stdout with a new file? FWIW, it's a third party product that I can't modify to change its logging model. EDIT redirecting over the file seems to have the same issue as the copy above - the file returns to its previous size next time it's written to: ls -l sample.log ; echo > sample.log ; ls -l sample.log ; sleep 10 ; ls -l sample.log -rw-rw-r-- 1 user group 1291999 Jun 11 2009 sample.log -rw-rw-r-- 1 user group 1 Jun 11 2009 sample.log -rw-rw-r-- 1 user group 1292311 Jun 11 2009 sample.log

  • File sizing issue in DOS/FAT

    - by Heather
    I've been tasked with writing a data collection program for a Unitech HT630, which runs a proprietary DOS operating system that can run executables compiled for 16-bit MS DOS with some restrictions. I'm using the Digital Mars C/C++ compiler, which is working well thus far. One of the application requirements is that the data file must be human-readable plain text, meaning the file can be imported into Excel or opened by Notepad. I'm using a variable length record format much like CSV that I've successfully implemented using the C standard library file I/O functions. When saving a record, I have to calculate whether the updated record is larger or smaller than the version of the record currently in the data file. If larger, I first shift all records immediately after the current record forward by the size difference calculated before saving the updated record. EOF is extended automatically by the OS to accommodate the extra data. If smaller, I shift all records backwards by my calculated offset. This is working well, however I have found no way to modify the EOF marker or file size to ignore the data after the end of the last record. Most of the time records will grow in size because the data collection program will be filling some of the empty fields with data when saving a record. Records will only shrink in size when a correction is made on an existing entry, or on a normal record save if the descriptive data in the record is longer than what the program reads in memory. In the situation of a shrinking record, after the last record in the file I'm left with whatever data was sitting there before the shift. I have been writing an EOF delimiter into the file after a "shrinking record save" to signal where the end of my records are and space-filling the remaining data, but then I no longer have a clean file until a "growing record save" extends the size of the file over the space-filled area. The truncate() function in unistd.h does not work (I'm now thinking this is for *nix flavors only?). One proposed solution I've seen involves creating a second file and writing all the data you wish to save into that file, and then deleting the original. Since I only have 4MB worth of disk space to use, this works if the file size is less than 2MB minus the size of my program executable and configuration files, but would fail otherwise. It is very likely that when this goes into production, users would end up with a file exceeding 2MB in size. I've looked at Ralph Brown's Interrupt List and the interrupt reference in IBM PC Assembly Language and Programming and I can't seem to find anything to update the file size or similar. Is reducing a file's size without creating a second file even possible in DOS?

  • sprintf() to truncate and not round a float to x decimal places?

    - by jerrygarciuh
    Hi folks, When calculating a golf handicap differential you are supposed to truncate the answer to 1 decimal place without rounding. No idea why but... I know how to do this using TRUNCATE() in mySQL SELECT TRUNCATE( 2.365, 1 ); // outputs 2.3 but I was wondering if sprintf() could do this? The only way I know to work with decimal places in a float is ... echo sprintf("%.1f", 2.365); // outputs 2.4 TIA JG

  • How to avoid Foreign Keys constraints for all tables in DB truncate ?

    - by eugeneK
    Hi, for designing purposes i need to truncate all DB which has lots of FK's. I cannot use DELETE command simply because some tables set with Identity of TinyInts and contain about 150 items. this is a query ( truncate all tables in selected DB ) i'm trying to run Declare @t varchar (1024) Declare tbl_cur cursor for select TABLE_NAME from INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE = 'BASE TABLE' OPEN tbl_cur FETCH NEXT from tbl_cur INTO @t WHILE @@FETCH_STATUS = 0 BEGIN EXEC ('TRUNCATE TABLE '+ @t) FETCH NEXT from tbl_cur INTO @t END CLOSE tbl_cur DEALLOCATE tbl_Cur What the best and easiest way to achieve truncate on DB with many FK's ?

  • java converting int to short

    - by changed
    Hi I am calculating 16 bit checksum on my data which i need to send to server where it has to recalculate and match with the provided checksum. Checksum value that i am getting is in int but i have only 2 bytes for sending the value.So i am casting int to short while calling shortToBytes method. This works fine till checksum value is less than 32767 thereafter i am getting negative values. Thing is java does not have unsigned primitives, so i am not able to send values greater than max value of signed short allowed. How can i do this, converting int to short and send over the network without worrying about truncation and signed & unsigned int. Also on both the side i have java program running. private byte[] shortToBytes(short sh) { byte[] baValue = new byte[2]; ByteBuffer buf = ByteBuffer.wrap(baValue); return buf.putShort(sh).array(); } private short bytesToShort(byte[] buf, int offset) { byte[] baValue = new byte[2]; System.arraycopy(buf, offset, baValue, 0, 2); return ByteBuffer.wrap(baValue).getShort(); }

  • html truncator in java

    - by sammichy
    Is there any utility (or sample source code) that truncates HTML (for preview) in Java? I want to do the truncation on the server and not on the client. I'm using HTMLUnit to parse HTML. UPDATE: I want to be able to preview the HTML, so the truncator would maintain the structure while stripping out the elements after the desired output length.

  • Truncating long strings with CSS: feasible yet?

    - by Sam Stokes
    Is there any good way of truncating text with plain HTML and CSS, so that dynamic content can fit in a fixed-width-and-height layout? I've been truncating server-side by logical width (i.e. a blindly-guessed number of characters), but since a 'w' is wider than an 'i' this tends to be suboptimal, and also requires me to re-guess (and keep tweaking) the number of characters for every fixed width. Ideally the truncation would happen in the browser, which knows the physical width of the rendered text. I've found that IE has a text-overflow: ellipsis property that does exactly what I want, but I need this to be cross-browser. This property seems to be (somewhat?) standard but isn't supported by Firefox. I've found various workarounds based on overflow: hidden, but they either don't display an ellipsis (I want the user to know the content was truncated), or display it all the time (even if the content wasn't truncated). Does anyone have a good way of fitting dynamic text in a fixed layout, or is server-side truncation by logical width as good as I'm going to get for now?

  • How to get last 12 digits from a sting in MySQL?

    - by Nick Gorbikoff
    Hello. How would I get last 12 digits of a string using mysql? Let's say I have a varchar field with a tracking number, that may be anywhere from 5 to 20 varchars long. But I only need to select last 12 digits or less if there are less. so in a field = 12345678123456789012 I would only need to get what's in brackets field = 12345678[123456789012] I saw a few examples using mid, etc, but they dont' produce the desired result or I can't find an example that makes sense :-( Thank you.

  • Truncating a table referenced by a foreign key

    - by born to hula
    Hey, We have two tables in a SQL Server 2005 database, A and B.There is a service which truncates table A every day. Recently, a foreign key constraint was added to table B, referencing table A. As a result, it isn't possible truncating table A anymore, even if table B is empty. Is there any workaround to get the same result as truncating table A? I've already tried the approach below but the identity wasn't reset. DBCC CHECKIDENT (TABLENAME, RESEED, 0) PS. before anyone points this as a duplicate, the different thing here is that I'm not allowed to drop constraints, nor creating any.

  • How can I truncate an NSString to a set length?

    - by nevan
    I searched, but surprisingly couldn't find an answer. I have a long NSString that I want to shorten. I want the maximum length to be around 20 characters. I read somewhere that the best solution is to use substringWithRange. Is this the best way to truncate a string? NSRange stringRange = {0,20}; NSString *myString = @"This is a string, it's a very long string, it's a very long string indeed"; NSString *shortString = [myString substringWithRange:stringRange]; It seems a little delicate (crashes if the string is shorter than the maximum length). I'm also not sure if it's Unicode-safe. Is there a better way to do it? Does anyone have a nice category for this?

  • Is there any JavaScript Library to intelligently truncate strings?

    - by j0ker
    I need to truncate strings in a side menu to make the fit into a div without a linebreak. The divs have a fixed width. I'm looking for a library to do that for me. If a string is too long to fit into the div, it should be truncated like: <div>This string is too long</div> == <div>This string is...ong</div> As you can see, the string is not only truncated by an ellipsis but the last three letters are also visible. This is meant to increase readability. The truncation should not care about spaces. Does anyone know of a library that includes such functionality? We're mainly using jQuery throughout the project. Thanks in advance!

  • C++: how to truncate the double in efficient way?

    - by Arman
    Hello, I would like to truncate the float to 4 digits. Are there some efficient way to do that? My current solution is: double roundDBL(double d,unsigned int p=4) { unsigned int fac=pow(10,p); double facinv=1.0/static_cast<double>(fac); double x=static_cast<unsigned int>(x*fac)/facinv; return x; } but using pow and delete seems to me not so efficient. kind regards Arman.

  • MSSQL: Copying data from one database to another

    - by DigiMortal
    I have database that has data imported from another server using import and export wizard of SQL Server Management Studio. There is also empty database with same tables but it also has primary keys, foreign keys and indexes. How to get data from first database to another? Here is the description of my crusade. And believe me – it is not nice one. Bugs in import and export wizard There is some awful bugs in import and export wizard that makes data imports and exports possible only on very limited manner: wizard is not able to analyze foreign keys, wizard wants to create tables always, whatever you say in settings. The result is faulty and useless package. Now let’s go step by step and make things work in our scenario. Database There are two databases. Let’s name them like this: PLAIN – contains data imported from remote server (no indexes, no keys, no nothing, just plain dumb data) CORRECT – empty database with same structure as remote database (indexes, keys and everything else but no data) Our goal is to get data from PLAIN to CORRECT. 1. Create import and export package In this point we will create faulty SSIS package using SQL Server Management Studio. Run import and export wizard and let it create SSIS package that reads data from CORRECT and writes it to, let’s say, CORRECT-2. Make sure you enable identity insert. Make sure there are no views selected. Make sure you don’t let package to create tables (you can miss this step because it wants to create tables anyway). Save package to SSIS. 2. Modify import and export package Now let’s clean up the package and remove all faulty crap. Connect SQL Server Management Studio to SSIS instance. Select the package you just saved and export it to your hard disc. Run Business Intelligence Studio. Create new SSIS project (DON’T MISS THIS STEP). Add package from disc as existing item to project and open it. Move to Control Flow page do one of following: Remove all preparation SQL-tasks and connect Data Flow tasks. Modify all preparation SQL-tasks so the existence of tables is checked before table is created (yes, you have to do it manually). Add new Execute-SQL task as first task in control flow: Open task properties. Assign destination connection as connection to use. Insert the following SQL as command:   EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL' GO   EXEC sp_MSForEachTable 'DELETE FROM ?' GO   Save task. Add new Execute-SQL task as last task in control flow: Open task properties. Assign destination connection as connection to use. Insert the following SQL as command:   EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL' GO   Save task Now connect first Execute-SQL task with first Data Flow task and last Data Flow task with second Execute-SQL task. Now move to Package Explorer tab and change connections under Connection Managers folder. Make source connection to use database PLAIN. Make destination connection to use database CORRECT. Save package and rebuilt the project. Update package using SQL Server Management Studio. Some hints: Make sure you take the package from solution folder because it is saved there now. Don’t overwrite existing package. Use numeric suffix and let Management Studio to create a new version of package. Now you are done with your package. Run it to test it and clean out all the errors you find. TRUNCATE vs DELETE You can see that I used DELETE FROM instead of TRUNCATE. Why? Because TRUNCATE has some nasty limits (taken from MSDN): “You cannot use TRUNCATE TABLE on a table referenced by a FOREIGN KEY constraint; instead, use DELETE statement without a WHERE clause. Because TRUNCATE TABLE is not logged, it cannot activate a trigger. TRUNCATE TABLE may not be used on tables participating in an indexed view.” As I am not sure what tables you have and how they are used I provided here the solution that should work for all scenarios. If you need better performance then in some cases you can use TRUNCATE table instead of DELETE. Conclusion My conclusion is bitter this time although I am very positive guy. It is A.D. 2010 and still we have to write stupid hacks for simple things. Simple tools that existed before are long gone and we have to live mysterious bloatware that is our only choice when using default tools. If you take a look at the length of this posting and the count of steps I had to do for one easy thing you should treat it as a signal that something has went wrong in last years. Although I got my job done I would be still more happy if out of box tools are more intelligent one day.
