  • Download Current WSJ.com Prime Rate

    - by Registered User
    I need to automatically download the current Wall Street Journal Prime Rate and load the data into my database. What is the best method for downloading this data automatically? I have come up with three possible solutions for doing this: Scrape a HTML web page from WSJ. Parse a RSS news feed from WSJ. Use some API that I haven't found from WSJ. Regarding solution 1, although I don't like solution 1 since it could easily break, it's the only one that I have worked out from end to end. It appears I can scrape this page with a WebRequest / WebResponse and read the text in this code: <tr> <td style="text-align:left" class="colhead">&nbsp;</td> <td class="colhead">Latest</td> <td class="colhead">Wk ago</td> <td class="colhead">High</td> <td class="colhead">Low</td> </tr> <tr> <td class="text">U.S.</td> <td style="font-weight:bold;" class="num">3.25</td> <td class="num">3.25</td> <td class="num">3.25</td> <td class="num" style="border-right:0px">3.25</td> </tr> Regarding solution 2, although I can implement a RSS reader solution, I don't see a way to reliably anticipate verbiage for changes in the Prime Rate. Therefore, I don't think this is as safe or reliable a way to get the data as solution 1. Regarding solution 3, I haven't found any published API's for checking money rates like the Prime Rate. If anyone knows of a web service or other API for checking money rates, then please let me know.

  • SerialPort not taking input. It throws it back at me!

    - by Mashew
    When I try to write an AT command to my GSM modem, it does not seem to take the command. I have used PuTTY to check that the command words, it does. I have checked to see if the port is opening, it does. What could I possibly be doing wrong? NOTE: The "lol" part is for debugging purposes. ;3 SerialPort sp = new SerialPort("COM3"); sp.BaudRate = 9600; sp.DataBits = 8; sp.StopBits = StopBits.One; sp.Parity = Parity.None; sp.Open(); if (sp.IsOpen == false) { sp.Open(); } Thread.Sleep(1000); sp.WriteLine("AT+CMGF=1"); Thread.Sleep(1000); string lol = sp.ReadExisting(); sp.Close(); return lol;

  • Why does use of H264 in sender/receiver pipelines introduce just HUGE delay?

    - by Serguey Zefirov
    When I try to create pipeline that uses H264 to transmit video, I get some enormous delay, up to 10 seconds to transmit video from my machine to... my machine! This is unacceptable for my goals and I'd like to consult StackOverflow over what I (or someone else) do wrong. I took pipelines from gstrtpbin documentation page and slightly modified them to use Speex: This is sender pipeline: #!/bin/sh gst-launch -v gstrtpbin name=rtpbin \ v4l2src ! ffmpegcolorspace ! ffenc_h263 ! rtph263ppay ! rtpbin.send_rtp_sink_0 \ rtpbin.send_rtp_src_0 ! udpsink host=127.0.0.1 port=5000 \ rtpbin.send_rtcp_src_0 ! udpsink host=127.0.0.1 port=5001 sync=false async=false \ udpsrc port=5005 ! rtpbin.recv_rtcp_sink_0 \ pulsesrc ! audioconvert ! audioresample ! audio/x-raw-int,rate=16000 ! \ speexenc bitrate=16000 ! rtpspeexpay ! rtpbin.send_rtp_sink_1 \ rtpbin.send_rtp_src_1 ! udpsink host=127.0.0.1 port=5002 \ rtpbin.send_rtcp_src_1 ! udpsink host=127.0.0.1 port=5003 sync=false async=false \ udpsrc port=5007 ! rtpbin.recv_rtcp_sink_1 Receiver pipeline: !/bin/sh gst-launch -v\ gstrtpbin name=rtpbin \ udpsrc caps="application/x-rtp,media=(string)video, clock-rate=(int)90000, encoding-name=(string)H263-1998" \ port=5000 ! rtpbin.recv_rtp_sink_0 \ rtpbin. ! rtph263pdepay ! ffdec_h263 ! xvimagesink \ udpsrc port=5001 ! rtpbin.recv_rtcp_sink_0 \ rtpbin.send_rtcp_src_0 ! udpsink port=5005 sync=false async=false \ udpsrc caps="application/x-rtp,media=(string)audio, clock-rate=(int)16000, encoding-name=(string)SPEEX, encoding-params=(string)1, payload=(int)110" \ port=5002 ! rtpbin.recv_rtp_sink_1 \ rtpbin. ! rtpspeexdepay ! speexdec ! audioresample ! audioconvert ! alsasink \ udpsrc port=5003 ! rtpbin.recv_rtcp_sink_1 \ rtpbin.send_rtcp_src_1 ! udpsink host=127.0.0.1 port=5007 sync=false async=false Those pipelines, a combination of H263 and Speex, work fine enough. I snap my fingers near camera and micropohne and then I see movement and hear sound at the same time. Then I changed pipelines to use H264 along the video path. The sender becomes: #!/bin/sh gst-launch -v gstrtpbin name=rtpbin \ v4l2src ! ffmpegcolorspace ! x264enc bitrate=300 ! rtph264pay ! rtpbin.send_rtp_sink_0 \ rtpbin.send_rtp_src_0 ! udpsink host=127.0.0.1 port=5000 \ rtpbin.send_rtcp_src_0 ! udpsink host=127.0.0.1 port=5001 sync=false async=false \ udpsrc port=5005 ! rtpbin.recv_rtcp_sink_0 \ pulsesrc ! audioconvert ! audioresample ! audio/x-raw-int,rate=16000 ! \ speexenc bitrate=16000 ! rtpspeexpay ! rtpbin.send_rtp_sink_1 \ rtpbin.send_rtp_src_1 ! udpsink host=127.0.0.1 port=5002 \ rtpbin.send_rtcp_src_1 ! udpsink host=127.0.0.1 port=5003 sync=false async=false \ udpsrc port=5007 ! rtpbin.recv_rtcp_sink_1 And receiver becomes: #!/bin/sh gst-launch -v\ gstrtpbin name=rtpbin \ udpsrc caps="application/x-rtp,media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264" \ port=5000 ! rtpbin.recv_rtp_sink_0 \ rtpbin. ! rtph264depay ! ffdec_h264 ! xvimagesink \ udpsrc port=5001 ! rtpbin.recv_rtcp_sink_0 \ rtpbin.send_rtcp_src_0 ! udpsink port=5005 sync=false async=false \ udpsrc caps="application/x-rtp,media=(string)audio, clock-rate=(int)16000, encoding-name=(string)SPEEX, encoding-params=(string)1, payload=(int)110" \ port=5002 ! rtpbin.recv_rtp_sink_1 \ rtpbin. ! rtpspeexdepay ! speexdec ! audioresample ! audioconvert ! alsasink \ udpsrc port=5003 ! rtpbin.recv_rtcp_sink_1 \ rtpbin.send_rtcp_src_1 ! udpsink host=127.0.0.1 port=5007 sync=false async=false This is what happen under Ubuntu 10.04. I didn't noticed such huge delays on Ubuntu 9.04 - the delays there was in range 2-3 seconds, AFAIR.

  • Some process does ICMP port scan on my OSX box and I am afraid my Mac got a virus

    - by Jamgold
    I noticed that my 10.6.6 box has some process send out ICMP messages to "random" hosts, which concerns me a lot. when doing a tcpdump icmp I see a lot of the following 15:41:14.738328 IP macpro bzq-109-66-184-49.red.bezeqint.net: ICMP macpro udp port websm unreachable, length 36 15:41:15.110381 IP macpro 99-110-211-191.lightspeed.sntcca.sbcglobal.net: ICMP macpro udp port 54045 unreachable, length 36 15:41:23.458831 IP macpro 188.122.242.115: ICMP macpro udp port websm unreachable, length 36 15:41:23.638731 IP macpro 61.85-200-21.bkkb.no: ICMP macpro udp port websm unreachable, length 36 15:41:27.329981 IP macpro c-98-234-88-192.hsd1.ca.comcast.net: ICMP macpro udp port 54045 unreachable, length 36 15:41:29.349586 IP macpro c-98-234-88-192.hsd1.ca.comcast.net: ICMP macpro udp port 54045 unreachable, length 36 I got suspicious when my router notified me about a lot of ICMP messages that don't get a response Does anyone know how to trace which process (or worse kernel module) might be responsible for this? I rebooted and logged in with a virgin user account and tcpdump showed the same results. Any dtrace magic welcome. Thanks in advance

  • Wowhead.com Site Framework

    - by Byran
    I'm building a community website (not WoW related) and am curious what, if any, framework(s) Wowhead may use. The general, non-WoW specific functions of the site are near identical to what I need. A few of the features I'm interested in are: Item page comments User/Account management Forums Blog Content Management Search box suggestion I'm sure allot of their site is custom built but I assume that some portions may be third-party solutions, like the forums and blog. I just don't want to reinvent the wheel if it's out there ready for me to make use of.

  • Which language to learn C# or Salesforce.com/apex for C++ programmer

    - by polapts
    Being a C++ programmer with 7-8 years of experience, I wanted to know the market trends. When I searched a little bit I found more jobs with keyword C# than C++ or Java. I am just wondering if it is a good idea to learn C# or Java from a career perspective. Also, I read somewhere about Salesforce/apex. It was mentioned that this is something in vogue. So my question is which technology I should go for C#/Java/Salesforce(Apex) from career perspective? Thanks

  • have PDF form, need to port to website

    - by Alex
    So here is what I have: a PDF form (job application) that a client is requesting to put on their website as a form and the data gets sent to them when an applicant on the site fills the form out. My idea is as follows: dissecting the PDF, taking its fields and making the HTML form, then processing on the server side, creating the new PDF and emailing as an attachment to the client. However, something tells me that there is a better, more effective way of doing it. Is that so?

  • New to C/C++ Using Android NDK to port Legacy code, getting compile errors

    - by Donal Rafferty
    I have been trying to take some old Symbian C++ code over to Android today using the NDK. I have little to no C or C++ knowledge so its been a chore, however has to be done. My main issue is that I'm having trouble porting what I believe is Symbian specifi code to work using the small C/C++ subset that is available with the Android NDK. Here is a picture of the compilation errors I'm getting using cygwin I was wondering if anyone could point me in the right direction on how to deal with these errors? For instance is TBool/Int/TUint/RPointerArray/RSocket a Symbian primitive and thats why it wont compile or is it something else? Also what is ISO C++? Any tutorials, guides or tips and help would be greatly appreciated.

  • Returning S_FALSE from a C# COM dll

    - by AntonyW
    I have a method defined in IDL as follows : interface IMyFunc : IDispatch { [id(1), helpstring("method GetNextFunction")] HRESULT GetNextFunction([in,out] long* lPos, [out, retval] BSTR* bstrName); } Using C++ I always implemented this as follows : STDMETHODIMP CMyFunc::GetNextFunction(long *nID, long *lPos, BSTR *bstrName) { if ( function to return ) { // setup return values; return S_OK; } else { // just exit return S_FALSE; } } Now I am implementing this in C# and have used tlbimp on the type library and ended up with : public string GetNextFunction(ref int nID, ref int lPos) I understand that this is because [out, retval] is used as the return type instead of the HRESULT as in C++. Is there a simple way to return the S_OK / S_FALSE values without changing the method definition? The only way I can see is that I have to use ildasm / ilasm to add preservesig so I end up with something like this : public int GetNextFunction(ref int nID, ref int lPos, ref string bstrName) I was wondering if there was some other way without doing the il compilation step.

  • Change Address/Port of WSDL EndPointAddress at runtime?

    - by Pretzel
    So I currently have 3 WSDLs added as Service References in my solution. They look like this in my app.config file (I removed the "bindings" field, because it's uninteresting): <system.serviceModel> <client> <endpoint address="http://localhost:8080/query-service/jse" binding="basicHttpBinding" bindingConfiguration="QueryBinding" contract="QueryService.Query" name="QueryPort" /> <endpoint address="http://localhost:8080/platetype-service/jse" binding="basicHttpBinding" bindingConfiguration="PlateTypeBinding" contract="PlateTypeService.PlateType" name="PlateTypePort" /> <endpoint address="http://localhost:8080/dataimport-service/jse" binding="basicHttpBinding" bindingConfiguration="DataImportBinding" contract="DataImportService.DataImport" name="DataImportPort" /> </client> </system.serviceModel> When I utilize a WSDL, it looks something like this: using (DataService.DataClient dClient = new DataService.DataClient()) { DataService.importTask impt = new DataService.importTask(); impt.String_1 = "someData"; DataService.importResponse imptr = dClient.importTask(impt); } In the "using" statement, when instantiating the DataClient object, I have 5 constructors available to me. In this scenario, I use the default constructor: new DataService.DataClient() which uses the built-in Endpoint Address string, which is fine and good. But I want the user of the application to have the option to change this value. 1) What's the best/easiest way of programatically obtaining this string? 2) Then, once I've allowed the user to edit and test the value, where should I store it? I'd prefer having it be stored in a place (like app.config or equivalent) so that there is no need for checking whether the value exists or not and whether I should be using an alternate constructor. (Looking to keep my code tight, ya know?) Any ideas? Suggestions?

  • COM library for Explorer-like system views

    - by chrisd
    To provide a Windows Explorer-like view of the user's system, we have been using the shell controls from LogicNP (formerly Sky Software), but these have deficiencies, e.g., no support for Win7 libraries. The vendor has not responded to our inquiries about updates, so we're looking to replace the package. Requirements: ActiveX (no managed code or MFC) Tree and list views of the system Per-item checkboxes 32- and 64-bit versions Any recommendations for a replacement product? TIA.

  • WiX - Gotchas for Combining COM and .NET components in the same installer

    - by cmsjr
    I have two products that are always installed in tandem. One is an ActiveX exe the other a C# application. I've gotten the ActiveX installer to build and function properly using WiX and I'd really like to combine both into a single installer. I'm feeling just about dangerous enough with WiX to attempt it, but would be interested in any advice (particularly if it is inadvisable).

  • Problem using a COM interface as parameter

    - by Cesar
    I have the following problem: I have to projects Project1 and Project2. In Project1 I have an interface IMyInterface. In Project2 I have an interface IMyInterface2 with a method that receives a pointer to IMyInterface1. When I use import "Project1.idl"; in my Project2.idl, a #include "Project1.h" appears in Project2___i.h. But this file does not even exist!. What is the proper way to import an interface defined into other library into a idl file? I tried to replace the #include "Project1.h" by *#include "Project1_i.h"* or *#include "Project1_i.c"*, but it gave me a lot of errors. I also tried to use importlib("Project1.tlb") and define my interface IMyInterface2 within the library definition. But when I compile Project2PS project, an error is raised (something like dlldata.c is not generated if no interface is defined). I tried to create a dummy Project1.h. But when Project2___i.h is compiled, compiler cannot find MyInterface1. And if I include Project1___i.h I get a lot of errors again! Apparently, it is a simple issue, but I don't know how to solve it. I'm stuck with that!. By the way, I'm using VS2008 SP1. Thanks in advance.

  • Is Android reference at android.com good enough

    - by the100rabh
    Hi, I am a C++ developer, but have a fair idea of Java as I learnt it in college 5years ago. I have been trying to learn programming for android. But instead of rushing to buy books, I have tried to read through the Android Dev Guide and learn from there making use of the sample applications. Thats besides SO ofcourse. I am trying to make some apps based on ideas I have. So my question is, Is it suitable or possible to learn android programming this way. Or is there something that I will be missing in all this.
