  • UIWebView doesn't scroll to the bottom of the webpage loaded/created

    - by tom
    I have a UIWebView inside a normal UIViewController. The content of the UIWebView is programming/dynamically created in my program, and it could be very long (multiple table rows). Somehow, after loading, the page won't scroll more then one and half screen of content when swipe on the screen. Because of that I can only see the beginning few rows of data, but not the many others after them. Why is that?

  • Using gprof with sockets

    - by Chris
    I have a program I want to profile with gprof. The problem (seemingly) is that it uses sockets. So I get things like this: ::select(): Interrupted system call I hit this problem a while back, gave up, and moved on. But I would really like to be able to profile my code, using gprof if possible. What can I do? Is there a gprof option I'm missing? A socket option? Is gprof totally useless in the presence of these types of system calls? If so, is there a viable alternative? EDIT: Platform: Linux 2.6 (x64) GCC 4.4.1 gprof 2.19

  • Exception throws: encapsulate them or not?

    - by Simon
    Hi there. Once I read an MSDN article that encouraged the following programming paradigm: public class MyClass { public void Method1() { NewCustomException(); } public void Method2() { NewCustomException(); } void NewCustomException() { throw new CustomException("Exception message"); } } Do you think this paradigm makes sense? Wouldn't it be enough to store the exception message in a static const field and then pass it to the exception's constructor, instead of encapsulating the whole exception throw?

  • What is the most painful development related mistake you have done and what you have learned?

    - by burak ozdogan
    What is the most painful programming mistake you have done and what lesson you have learn after? I guess mine was making a release to production on the development code which was not tested yet. The lesson-learned: Delete any projects that can trigger a release on the live application from CCTray. I only add them when a release to production is necessary since then. And once I am done, I delete them from my project lists.

  • why multipart/x-mixed-replace is needed for Comet?

    - by Morgan Cheng
    I'm reading this article about Comet http://en.wikipedia.org/wiki/Comet_(programming). It mentions that browser should support multipart/x-mixed-replace to make XmlHttpRequest Streaming possible. Why this multipart/x-mixed-replace is necessary? Without this header, HTTP response can still be chunked and sent piece by piece to browser, right?

  • Cost of sending XMPP messages via Google App engine

    - by Alfred
    Hopefully this question is allowed over here. It does not really have to do with programming per se but with the costs associated with it. My question is: "How much does sending/receiving XMPP messages cost". I can find all the information about email etc. But I could not find information about costs sending/receiving XMPP messages.

    - by iaagty
    I'm looking for a complete list of security guidelines for programming and deploying PHP web sites and applications on an Apache (Linux) server. Basically, a "security check list" to run through before finishing a project. I.e., Cross Site Scripting Cross Site Request Forgery Sanitize form data that goes into database Disable register globals and error reporting in custom php.ini Upload files below web root ...(the list goes on) I did some searching on the internet and in this forum, but couldn't find a comprehensive, succinct, and complete list of guidelines. Thanks in advance.

  • How to build a widget for my website

    - by Gublooo
    Hey guys I'm very new to the whole programming - so far I only have experience with building websites, database etc. I currently have a website where users can share their online purchases. I want to build a widget that other websites can integrate on their site. Users should be able to insert their purchases directly through this widget without having to come to my website. Thats the idea but I have no idea how to go about it - can anyone point me in the right direction. Thanks

  • VB6 code for Reading/Writing Windows Registry values

    - by Clay Nichols
    I'm looking for a good example of reading and writing to the Windows Registry using VB6. Yes, I know there are lots of mediocre examples. I spent an hour googling and testing. Some were incredibly complex, others had only some of the functions, and almost none of it had been vetted in any way (voted on). Since Stack Overflow is intended to the canonical location for answers to programming questions, it seems reasonable to post it here.

  • How Proxy server works with tcp/http connections?

    - by Vivek
    Since I am a beginner in the world of internet/networking, I always mess up with these kinds of doubts in my head while programming ;) .. My doubts are, While working behind a proxy, how my requests and responses work? Means my request headers and data will first reach to Proxy server- then proxy server sends it(same headers and data) to corresponding server. And server responses to it with a response header and body to the proxy server-then proxy server sends it to my computer. Wright? While using websockets we are upgrading our http connection to tcp. At this time what is happening @ Proxy server? Does the proxyserver also upgrades its connection to plain TCP? After opening such TCP connections, does the proxy server able to track/log those socket messsages? And most importantly, Is the proxy server transparent or acting like an original server infront of a client? Thanks for any answers or helpful links in advance.

  • TcpListener problem - re-binding to same port with different local addresses

    - by Zvika
    I'm trying to do the following: listen on some port for loopback connections only, and then start listening on any IP address. Here is the code: TcpListener l1 = new TcpListener(new IPEndPoint(IPAddress.Loopback, 12345)); l1.Start(); Socket s = l1.AcceptSocket(); Console.ReadKey(); //s.Close(); l1.Stop(); TcpListener l2 = new TcpListener(new IPEndPoint(IPAddress.Any, 12345)); l2.Start(); l2.AcceptSocket(); Console.ReadKey(); The problem is that if a client connects while listening on the Loopback address (l1), then no other client can connect to the Loopback address when the second listener (l2) starts listening. why is that? Another thing I noticed is that if I close all clients that connected to l1 (the remarked line), then l2 does accept loopback connections. Any ideas?

  • Question with "extern" in C

    - by why
    When programming, I would like to split one large file(which contains main function) to many small files, so there is one common case: functions in small files can modify the var from main file, so i think extern is very useful! for instance: in main.c extern int i = 100; in small.c extern int i; fprintf(stdout, "var from main file: %d\n", i); I just want to know is my understanding right?

  • Nowaday C++ projects for Windows

    - by Andrew Florko
    Please, describe nowadays projects you took part in where C++ platform was preferred to .net where .net runtime could be installed. Some of my friends works in SCADA area. They have to program microcontrollers with Linux Embedded and so on. So my friends have nearly no choice in programming tools. But when you had, why did you prefer C++ ?
