• Issue in CheckedChanged event

  - by Gaddigesh

  I have a check box and I have subscribed for the CheckedChanged event. The handler does some operations in there. I check and uncheck the checkbox programmatically (ex: chkbx_Name.Checked = true), and the CheckedChanged event gets fired. I want this event to be fired only when I manually check or uncheck it. Is there any way to avoid firing of this event when i check/uncheck it programmatically?

• Is there any analog of TCPvcon which allows to close TCP connection on remote machine?

  - by Miollnyr

  Hi, I started to use SysInternals suite, and it is great. But I wonder, whether there is any analog of TCPvcon, which allows to logon to remote machine, like psexec does, and then get list of TCP connections from there (similar to pslist functionality), and then to close some of connections (similar to pskill functionality). I am speaking about windows console tools and I would like to avoid installing something on remote machine is this is possible.

• When and where should I add a view to a UITableView's footer?

  - by camelCase

  I am populating a UITableViewController's UITableView through code only. At the bottom of the table I wish to position a button that scrolls into view as the user scrolls to the bottom of the table. When in the UITableViewController life cycle should I populate the table footer with a button? viewDidLoad? p.s. I wish to avoid using section footers in the UITableView.

• Why do I get so many errors building my Android project with Ant?

  - by synic

  Now that I sort of know my way around the SDK/API, I've switched from Eclipse back to my favorite text editor, which means I have to use ant to build my project, however: It seems every other time I compile the project, a lot of drawables get corrupted, resources lose their ids (resulting in NPEs in the code), or classes throw "Verify Errors". The only way to fix this is by removing the bin and gen folders, and recompiling, which is obviously annoying. Is there any way to avoid this? btw, I'm using ant 1.7.1, java version "1.6.0_20"

• C: performance of assignments, binary operations, et cetera...

  - by Shinka

  I've heard many things about performance in C; casting is slow compared to normal assignments, functional call is slow, binary operation are much faster than normal operations, et cetera... I'm sure some of those things are specific to the architecture, and compiler optimization might make a huge difference, but I would like to see a chart to get a general idea what I should do and what I should avoid to write high-performance programs. Is there such a chart (or a website, a book, anything) ?

• freebsd dev server on virtualbox over windows

  - by g_kaya

  I need a unixy environment for development purposes. I hate doing things on windows but it is more stable for daily use and I don't have a mac, so I'm having to use windows (7). I want to run freebsd in a virtual machine, configure it to be the localhost server, be able to connect using ssh (within my home-network) and be able to install vbox guest addons. If guest additions aren't the best, I can use solaris or linux flavours. I need no gui. I don't know anything about network stuff, so I need a detailed explanation from vise people here, or a nice doc to read. Edit : To be more specific as requested, I use following on unices: *django 1.4 *apache *python (2.7) *emacs *mysql *probably node.js *bash scripting I use windows to be able to do daily things easily, like connecting to my tablet, browsing and learning java. And I don't want to use linux as my desktop os, beacuse it gets broken a lot, it's annoying to maintain wlan problems and some more.

  - by WilliamKF

  I have an unsigned char array that I need in a std::string, but my current way uses reinterpret_cast which I would like to avoid. Is there a cleaner way to do this? unsigned char my_txt[] = { 0x52, 0x5f, 0x73, 0x68, 0x7e, 0x29, 0x33, 0x74, 0x74, 0x73, 0x72, 0x55 } unsigned int my_txt_len = 12; std::string my_std_string(reinterpret_cast<const char *>(my_txt), my_txt_len);

• Secure automated SSH/SFTP after reboot

  - by mozillalives

  I need to give a daemon ssh access to a particular server. Currently I have it setup to use ssh keys and a keychain, but the trouble with this method is if a reboot occurs. Unless I'm missing something, I would need to login after a system reboot and add the key to the keychain. Is there a way I could avoid/automate this? I'm considering using expect if I can't find any other way.

• Is it bad to throw exceptions to trigger server errors, eg. 404 Page Not Found?

  - by Pheter

  I am working on a PHP framework and am currently designing error handling. Based on what I have read on SO, I should only use exceptions for, well, exceptional situations. Therefore throwing an exception when an incorrect password is entered is wrong. Should I avoid using exceptions when I want to trigger a server error? If so, should I write my own error handling class?

• Read a file from line X to line Y ?

  - by thedp

  Hello, Is there a way to read a file in PHP5 from line X to line Y into a string, without reading the entire file. I would like to return huge files (10,000+ lines) using ajax requests. Each request will provide the client with additional lines. And due to the fact that the file can reach large sizes, I would like to avoid reading it whole over and over again. Thank you.

• MySQL Cluster transaction isolation level - READ_COMMITTED

  - by Doori Bar

  I'm learning by mostly reading the documentation. Unfortunately, http://dev.mysql.com/doc/refman/5.1/en/set-transaction.html#isolevel_read-committed doesn't say anything, while it says everything. Confused? Me too. ndb engine supports only "READ_COMMITTED" transaction isolation level. A. It starts by saying "sets and reads its own fresh snapshot", which I translate to: The transaction is having a separated 'zone' which whatever it stores there - is what it reads back. B. While out-side of the transaction, the old-values are unlocked. C. It continues with: "for locking reads" sentence - No idea what it means. Question: they claim only READ_COMMITTED transaction isolation level is supported, but while handling a BLOB or a TEXT, they say the isolation is now "locked for reading" too. So is it a contradiction? can a transaction LOCK for reading just as well while handling something other than BLOB/TEXT? (such as integers)

• In Bash, how do you access command line arguments inside a function?

  - by DonGar

  I'm attempting to write a function in bash that will access the scripts command line arguments, but they are replaced with the positional arguments to the function. Is there any way for the function to access the command line arguments if they aren't passed in explicitly? # Demo function function stuff { echo $0 $* } # Echo's the name of the script, but no command line arguments stuff # Echo's everything I want, but trying to avoid stuff $*

• Setting up a transparent proxy with only one box.

  - by Scott Chamberlain

  I am playing around with transparent proxies, unfortunately I do not have two machines to test it out with. The current way I am doing things is the program makes a request to a computer on port 80, I use iptables -t nat -A OUTPUT -p tcp --destination-port 80 -j REDIRECT --to-port 1234 to redirect to my proxy that I am playing with. the proxy will send out a request to port 81 (as all outbound port 80 are being fed back in to the proxy so I want to do something like iptables -t nat -A OUTPUT -p tcp --destination-port 81 -j DNAT --to-destination xxxx:80 The problem lies with the xxxx part. How do I change the destination port without changing changing the destination ip? Or am I doing this setup completely wrong, I am learning after all and constructive criticism is definitely appreciated. The machine I am using is pretty low end so I would like not not have to create a VM with a second box unless absolutely necessary.

• Calculate rolling / moving average in c or c++

  - by Biohazard

  I know this is achievable with boost as per: Using boost::accumulators, how can I reset a rolling window size, does it keep extra history? But I really would like to avoid using boost. I have googled and not found any suitable or readable examples. Basically I want to track the moving average of an ongoing stream of a stream of floating point numbers using the most recent 1000 numbers as a data sample. What is the easiest way to achieve this?

• Do I have to call release on an objective-c retain class variable when setting it to a new object?

  - by Andrew Arrow

  Say I have: @property (nonatomic,retain) NSString *foo; in some class. And I call: myclass.foo = [NSString stringWithString:@"string1"]; myclass.foo = [NSString stringWithString:@"string2"]; Should I have called [myclass.foo release] before setting it to "string2" to avoid a memory leak? Or the fact that nothing is pointing to the first "string1" object anymore is good enough? And in the dealloc method [foo release] will be called.

• Why SVN makes read-only my files after check out or update?

  - by eKek0

  Working with an standard configuration of the server, without any lock, my files are read-only after every check out or update to the working copy. I have to set them to be not read-only to continue working, but besides this shouldn't be happening, it's uncomfortable. Anybody knows how to avoid this behavior?
