• WSDL vs DLL. Which is better?

  - by Lopper

  I would like to create a reusable interface to transfer some proprietary information over the TCP/IP connection. If given only the choice of either WSDL or DLL, what are the pros and cons of using each? This is assuming that Windows OS is used.

• Windows Server 2003 VPN and Local network

  - by depo

  I have some problems reaching local network , where VPN Windows 2003 server stands. I have a network, which has a VPN server (LAN ip 10.0.0.201). I created a VPN server on that server with different subnet for VPN users (10.0.5.0). After VPN connection is initiated , i am able to acces only 10.0.0.201, but not other PC, which belongs to that network ( all i need to access 10.0.0.203 and 10.0.0.208). I think i need to add somethink to static route table, or not?

• How to find multiple words on the same line in Notepad++

  - by Mike

  I have a 4MB log file from the Windows XP firewall which I'm trying to find lines that have both DROP and an IP and a port number. My regex-fu is weak and I'm assuming this is the reason I'm struggling. The words "DROP", "10.1.1.1" (for example) and "8801" need to be found on the same line and may be spread across the line and separated by one or more other words. Any help (or suggestions of another method to do this) are much appreciated.

• How do I identify which MySQL slave has responded?

  - by Kynth

  I have a MySql Master server replicating to three Slaves. A legacy website is performing load-balanced Reads from the Slaves. Is there a method of identifying from the website which of the Slaves is serving a Read request? I'd prefer a function that I can use to return a server name or ip address as part of the SELECT, but any reasonable method will do. Thank you in advance.

• How does a tcp connection pool distinguish between different clients

  - by stackazcat

  In my understanding, a tcp connection in a connection pool can only be reused if the same client is connected to the server. So the server tries to connect to a specific client (i.e. fetches a connection from the pool) how does the server do it? Do I have to provide IP of the client or something?

• How can I prevent javascript errors in my selenium tests from hanging my build system?

  - by lowellk

  We are having a problem with our selenium tests which run in IE on a virtual machine. Whenever there is a javascript error, a popup shows up and puts our system into a 'stuck' state - a user has to go clear that and restart the selenium test run. Is there a way to prevent the javascript error popup from putting the system into its stuck state? Would setting window.error be of any help here?

• Passing data to overridden base method in C#

  - by UpTheCreek

  Bit of a dumb question, but I'm wondering what the accepted way of passing data from back to an overridden base method is in c#. e.g. I guess I could do: class A { int x; public virtual void DoStuff() { Console.WriteLine(x); } } class B : A { public override void DoStuff() { x = 1; base.DoStuff(); } } But is there a better method that for example doesn't require the use of a member variable?

• C++ Performance/memory optimization guidelines

  - by ML

  Hi All, Does anyone have a resource for C++ memory optimization guidelines? Best practices, tuning, etc? As an example: Class xxx { public: xxx(); virtual ~xxx(); protected: private: }; Would there be ANY benefit on the compiler or memory allocation to get rid of protected and private since there there are no items that are protected and private in this class?

• Robotium BDD with Cucumber

  - by LucasGomes

  I want to know if you guys know how to make BDD tests with Robotium. As I research Robotium works with a different Virtual Machine (Dalvik) so I cannot run as Junit Test (Only with Android Junit Test). So I found a possible solution to run Robotium with Junit with RoboRemote https://github.com/groupon/robo-remote. But when i tried to integrate with cucumber the tests became unstable. So you guys know some way to make BDD tests using Robotium?

• Print layout of C++ object with g++ compiler

  - by zaheer

  Is there a way to print the layout of a C++ object using the g++ compiler or any other means. A simplified example (assuming int takes 4 bytes) class A{ int a; }; class B:public A{ int b; } so the output would be A - 0 4 + a + B- 0 4 8 + A.a + b + It would be useful to understand the layout of objects (in my case virtual machine code). Thanks in advance. Regards, Zaheer

• 2 Controls, 1 event

  - by DTown

  I have 2 input textboxes that take a host or IP. When the user leaves an input box an event is fired that checks the input to see if it is actually a live computer. The results are then put into the appropriate label. My question is, should I be using separate events for each input box, since they update different labels? Or, can I use 1 event and check who the caller was, then update the appropriate label?

• .htaccess or PHP protection code against multiple speedy requests

  - by Phil Jackson

  Hi, I am looking for ideas for how I can stop external scripts connecting with my site. I'm looking for the same kind of idea behind Google. As in if a certain amount of requests are made per a certain amount of time then block the IP address or something. I thought there maybe a htaccess solution if not, I will write a PHP one. Any ideas or links to existing methods or scripts is much appreciated. Regards Phil

• Is it possible to programatically log access to a windows share (SMB share) using the .Net framework

  - by Ravi

  Just wondering if it is possible to figure out who has read files from a Windows share (using .NET ideally but win32 native will do)? What I'm try to do is create something like awstats for a windows share so I can see who is accessing what and which are the most popular files. I'm not interested in changes - I just want to log access (with time) along with ip / hostname and what file.

• On linux, how to check if port is in listen state without trying to connect.

  - by Daniel

  Hi, How do I check with C if a port on my local machine (if required by passing an IP or interface, too), is in listen state? I don't want to connect to this port for checking because I don't want to irritate the service behind this port. I want to use this to add the missing net.tcp.listen item to Zabbix.

• placement new to defer to a different constructor

  - by Jonathan Swinney

  Is this safe? I'm not using any virtual functions in my actual implementation, but I'm tempted to believe that even if I was, it would still be safe. class Foo { Foo() { // initialize things } Foo( int ) { new ( this ) Foo(); } }

• Features to remove from C++

  - by Justin Ethier

  This question was inspired by What features would you like to see added to C++? (also see What features do you miss in C++?). C++ is a great general-purpose language, but perhaps too general and feature-rich: multiple inheritance, operator overloading, manual memory management, templates, smart pointers, virtual destructors, legacy frameworks (think MFC), and I could go on. Is there any one feature or aspect of C++ that you would like removed to make our lives easier as C++ developers? One feature per answer, please.
