• Correct order of overrides for a composite control based on an abstract one

  - by mattdwen

  I'm writing a set of C# composite web server controls for displaying dialog boxes. I want to have one abstract class which handles the basic layout and things like titles of the control, then have a set of derived ones which render child controls at a specific point. I forsee three distincts methods: renderOpeningHtml handled by the abstract class, renderCustomControls as done by the derived class, and renderClosingHtml by the abstract class again, except I can't figure the life cycle of a CompositeControl and what methods to use when.

• When is #include <new> library required in C++?

  - by Czarak

  Hi, According to this reference entry for operator new ( http://www.cplusplus.com/reference/std/new/operator%20new/ ) : Global dynamic storage operator functions are special in the standard library: All three versions of operator new are declared in the global namespace, not in the std namespace. The first and second versions are implicitly declared in every translation unit of a C++ program: The header does not need to be included for them to be present. This seems to me to imply that the third version of operator new (placement new) is not implicitly declared in every translation unit of a C++ program and the header <new> does need to be included for it to be present. Is that correct? If so, how is it that using both g++ and MS VC++ Express compilers it seems I can compile code using the third version of new without #include <new> in my source code? Also, the MSDN Standard C++ Library reference entry on operator new gives some example code for the three forms of operator new which contains the #include <new> statement, however the example seems to compile and run just the same for me without this include? // new_op_new.cpp // compile with: /EHsc #include<new> #include<iostream> using namespace std; class MyClass { public: MyClass( ) { cout << "Construction MyClass." << this << endl; }; ~MyClass( ) { imember = 0; cout << "Destructing MyClass." << this << endl; }; int imember; }; int main( ) { // The first form of new delete MyClass* fPtr = new MyClass; delete fPtr; // The second form of new delete char x[sizeof( MyClass )]; MyClass* fPtr2 = new( &x[0] ) MyClass; fPtr2 -> ~MyClass(); cout << "The address of x[0] is : " << ( void* )&x[0] << endl; // The third form of new delete MyClass* fPtr3 = new( nothrow ) MyClass; delete fPtr3; } Could anyone shed some light on this and when and why you might need to #include <new> - maybe some example code that will not compile without #include <new> ? Thanks.

• Wrong source IP when accessing internet directly from TMG server

  - by jarod1701

  Hi everyone, after implementing a ForeFront TMG server I'm facing only one problem: After I added a second IP to the external adapter I had to manually set "NAT Address Selection" inside the network rule "Internet Access" to the first IP since all others would get blocked by the CISCO firewall. This configuration works as long as traffic comes from the internal network (e.g. browser on clients). Traffic from the TMG directed to the internet always carries the second IP as it's source address and gets blocked. All our other TMGs/ISAs are running fine and I never came across this problem- Does anybody have a clue, coz I don't?! Kevin

• Delaying emails in PHP to avoid exceeding server limit

  - by Andrew P.

  Okay, so here's my problem: I have a list of members on a website, and periodically one of the admins my site (who are not very web or tech savvy) will send a newsletter to the memberlist. My current memberlist is well over 800 individuals long. So, I wrote an email script that sends the email to the full memberlist, with the members listed in the Bcc header. However, I've discovered that my host server has a limit of 300 emails per hour, which I apparently exceed even though the members are listed in the Bcc field. (I wasn't previously aware that the behaviour of Bcc was to send separate emails for each name on the list...) After some thought, I've come to the conclusion that my only solution is to have my script send only the email to only the first 300 emails, wait an hour, and send a second email to the next three hundred, wait another hour, and so on until I've sent the email to the whole member list. Looking around on the internet, I've seen some other solutions people have come up with for delaying emails in PHP. Sleep() is obviously not an option, because I can't just leave the script open and running for 3 or four hours. I've seen some people suggest cron jobs, but I'm not sure how feasible it would be to create three new cron jobs every time I send an email, use them once, and then delete them afterward. The final (and what I think is the smartest) solution I've seen, is to have a table in my database to temporarily store the emails to be delayed and sent later, and then create a cron job that checks this sql table every hour or so, compares the timestamp of the row to the current timestamp, and then sends the email if an hour has passed. So I'm asking you all which method you would recommend. Is there an easier solution that I've completely looked over (aside from getting a different hosting plan. ha!), or is there a cleaner way to do it than the database / cron job approach? tl;dr: I have 800 emails to send in an hour on a server that limits me to 300/hr. Using PHP, find a way to get around this problem in a way that the person sending the email needs only to click "send."

• Where do interfaces belong in a multitier application

  - by Russell Steen

  So say you have a three tier application with the tiers UI, Services, and Repository for a simple application, let's say saving addresses. If AddressService has an interface IAddressService, where does that interface belong? I know that "in the address service" may seem like an obvious answer, but if it's in the address service it would seem to defeat the point of having the interface such that any service library could be swapped in as long as it implemented IAddressService. (specifically this is in a .net problem space, but it's probably more general so it's tagged architecture)

• allowing index access only with .htaccess

  - by YsoL8

  Hello I have this in my .htaccess file, in the site root: Options -Indexes <directory ../.*> Deny from all </directory> <Files .htaccess> order allow,deny deny from all </Files> <Files index.php> Order allow,deny allow from all </Files> What I'm trying to achieve is to block folder and file access to anything that isn't called index.php, regardless of which directory is accessed. I have the folder part working perfectly and the deny from all rule is working as well - but my attempt to allow access to index.php is failing. Basically could someone tell me how to get it working?

• Non-Registry Fix for Secondary Mailboxes Sent Items

  - by Jai Kang

  There is a known issue with Outlook and Exchange where "secondary" mailboxes which are mounted in the same profile, e.g. "John Doe" + CorpMailbox1, CorpMailbox2, CorpMailbox3 will place "sent items" from the secondary mailboxes (e.g. CorpMailbox1) in the user's (e.g. "John Doe") Sent Items folder. There is a registry value (something like DelegateSentItems) to semi-fix this, but I'm looking for an Exchange-side solution. It seems like, at some point, an admin made CC rules to fix this, and for the mailboxes where I see a BCC rule: any item sent to [address] BCC to [address]. The behavior "fixes" the issue, but when I duplicate this work-around for new shared mailboxes, the email ends up in the Inbox and not the Sent Items for the shared mailbox. I don't believe there is any outlook/client-side shenanigans going on, as the intended behavior for the older mailboxes works for new PCs/Users (new imagse) without any Outlook Mailbox Rules.

• Exchange 2007: Auto reply message to senders (server side)

  - by Mestika

  Hi everyone and marry Christmas, I’ve to create an auto-reply for some of the users in my organization where, when a person sends an E-mail to e.g. [email protected] is faced with an automatically auto-reply with some message “closed during the holidays. We are back at… etc. etc. etc.”. I’ve tried to create a Transport Rule on our Exchange server but the only option I can find in the actions-window is to reply with a “Bounce message to sender with enhanced status code” but I guess that is not the precise action I’m looking for. How can I set up a server-side auto-reply, apply it to only a fixed number of users in my organization and create a message to the senders (which is outside the organization)? Sincerely Mestika

• re: 3ware raid 10 (4drive) suggested stripe size suggestions?

  - by dasko

  looked around on the site but nothing really concrete on my question. i will have about 120GB of data total, files are made up of 5MB files, excel, word and about 25 .pst files that are about 1.2GB each. Yes they use .pst over network, even though it is not recommended this is legacy setup without issue so we will continue to support this for another year or so. I need to know what you think about a stripe size of 256kb for the raid 10 based on the above requirements. I did try and bench with these settings and it seems alright without any real issue, just trying to rule out anything i might of missed. thanks.

• cross platform keyboard/mouse input recommendation

  - by Jay

  Does anyone have any suggestions for a good cross platform input library? I'd like to get: * at least keyboard and mouse input * on at least the big three operating systems * Small/fast * C or C++ * permissive licensing gpl2/mit/free/etc. So far I've seen: * OIS (used in Ogre) http://sourceforge.net/projects/wgois/ * SDL (used everywhere it seems, might be a clue) http://www.libsdl.org/index.php * Allegro http://www.talula.demon.co.uk/allegro/readme.html Has any one used any of these, or know of something else that might be good? Thanks

• Scala: custom control structures with several code blocks

  - by Vilius Normantas

  Is it possible to create a custom control structure with several code blocks, in the fashion of before { block1 } then { block2 } finally { block3 }? The question is about the sugar part only - I know the functionality can be easily achieved by passing the three blocks to a method, like doInSequence(block1, block2, block3). A real life example. For my testing utilities I'd like to create a structure like this: getTime(1000) { // Stuff I want to repeat 1000 times. } after { (n, t) => println("Average time: " + t / n) }

• Original sender is not correctly identified when spam is forwarded

  - by Stephan Burlot

  I have a forwarding rule with Postfix that forwards all messages to my main email address. When a spam message is sent to one of my emails, it is forwarded but the sender is shown as being the forwarding domain, not the spammer's domain. Real example: mywebsite.com is hosted on Linode. [email protected] sends an email to [email protected] the mail is forwarded to [email protected] my email hosting (anotherwebsite.com) sees it's spam and sends a message to [email protected] and Linode reports a TOS violation. I have modified my postfix settings so I now use RBL, but if a message goes through, it may happen again. How can I prevent this to happen again? Is there some settings to change on Postfix so the original sender is correctly identified? Thanks Stephan

• Internal+external interfaces with multiple default gateways on win2003

  - by fileitup

  Im trying to set up several web servers for a load balanced cluster and need to have each server connected to the internal network (for load balancing) as well as to an external network (internet - for administration). I have two NICs but since I cant set two default gateways I have the external gateway as default and the internal as a route rule. This setup only works half way - the internal network is fine but I cant log in from outside or see the web from the box. If I switch the gateways remote login/web will work, but the internal wont. Im sure someone encountered this before but wasnt able to find anything online. Any help will be appreciated.

• Google Chrome calling nypost.com every ~5 seconds

  - by TonyM

  I'm using Chrome 21.0.1180.49 beta on Mac OS X 10.7.4. Did some Googling and can't figure this out. I visited a page on nypost.com earlier this morning. Just noticed that Little Snitch is reporting that nypost.com is being called every 4-6 seconds or so. I closed the tab after reading the story, a few hours ago. I created a rule in Little Snitch denying access to nypost.com, but Chrome is apparently still connecting to it. (1) Why? and (2) How can I put an end to this? Thanks in advance for any thoughts.
