  • HttpClient POST fails to submit the form + resulting string is cut-off (incomplete)

    - by Jayomat
    Hi, I'm writing an app to check for the bus timetable's. Therefor I need to post some data to a html page, submit it, and parse the resulting page with htmlparser. Though it may be asked a lot, can some one help me identify if 1) this page does support post/get (I think it does) 2) which fields I need to use? 3) How to make the actual request? this is my code so far: String url = "http://busspur02.aseag.de/bs.exe?Cmd=RV&Karten=true&DatumT=30&DatumM=4&DatumJ=2010&ZeitH=&ZeitM=&Suchen=%28S%29uchen&GT0=&HT0=&GT1=&HT1="; String charset = "CP1252"; System.out.println("startFrom: "+start_from); System.out.println("goTo: "+destination); //String tag.v List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("HTO", start_from)); params.add(new BasicNameValuePair("HT1", destination)); params.add(new BasicNameValuePair("GTO", "Aachen")); params.add(new BasicNameValuePair("GT1", "Aachen")); params.add(new BasicNameValuePair("DatumT", day)); params.add(new BasicNameValuePair("DatumM", month)); params.add(new BasicNameValuePair("DatumJ", year)); params.add(new BasicNameValuePair("ZeitH", hour)); params.add(new BasicNameValuePair("ZeitM", min)); UrlEncodedFormEntity query = new UrlEncodedFormEntity(params, charset); HttpPost post = new HttpPost(url); post.setEntity(query); InputStream response = new DefaultHttpClient().execute(post).getEntity().getContent(); // Now do your thing with the facebook response. String source = readText(response,"CP1252"); Log.d(TAG_AVV,response.toString()); System.out.println("STREAM "+source); EDIT: This is my new code: try { HttpClient client = new DefaultHttpClient(); String getURL = "http://busspur02.aseag.de/bs.exe?SID=5FC39&ScreenX=1440&ScreenY=900&CMD=CR&Karten=true&DatumT="+day+"&DatumM="+month+"&DatumJ="+year+"&ZeitH="+hour+"&ZeitM="+min+"&Intervall=60&Suchen=(S)uchen&GT0=Aachen&T0=H&HT0="+start_from+"&GT1=Aachen&T0=H&HT1="+destination+""; HttpGet get = new HttpGet(getURL); HttpResponse responseGet = client.execute(get); HttpEntity resEntityGet = responseGet.getEntity(); if (resEntityGet != null) { //do something with the response Log.i("GET RESPONSE",EntityUtils.toString(resEntityGet)); } } catch (Exception e) { e.printStackTrace(); } But the output file is cut-off. If I do the same request in a browser I get like 14 different routes. Now the file suddenly stops and I only get 3 routes.... what's wrong? 04-30 12:19:12.362: INFO/GET RESPONSE(256): <!-- Ausgabebereich (automatisch erzeugt) --> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <div align="center"> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <p></p> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <p>Ihr Fahrplan für die Verbindung von Aachen, Kaiserplatz nach Aachen, Karlsgraben am Freitag, den 30.04.2010 (Koniginnedag), Abfahrten ab 12:19 Uhr</p> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <table class="Result"> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <tr> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <th class="fussnote">Fussnote</th> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <th class="fahrzeug">Fahrzeug</th> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <th class="abfahrt">Abfahrt</th> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <th class="haltestellean">Haltestelle</th> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <th class="linie">Linie</th> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <th class="haltestelleab">Haltestelle</th> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <th class="ankunft">Ankunft</th> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <th class="fahrzeit">Fahrzeit/Tarif</th> 04-30 12:19:12.362: INFO/GET RESPONSE(256): </tr> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <tr> 04-30 12:19:12.362: INFO/GET RESPONSE(256): <td>&nbsp;</td><td>&nbsp;<img src="http://www.busspur.de/logos/efa-bus.gif" title="Niederflurbus"></td><td>12:23</td><td title="lc0">Aachen, Kaiserplatz [Heinrichsalle Ri.

  • Uneditable file and Unreadable(for further processing) file( WHY? ) after processing it through C++

    - by mgj
    Hi...:) This might look to be a very long question to you I understand, but trust me on this its not long. I am not able to identify why after processing this text is not being able to be read and edited. I tried using the ord() function in python to check if the text contains any Unicode characters( non ascii characters) apart from the ascii ones.. I found quite a number of them. I have a strong feeling that this could be due to the original text itself( The INPUT ). Input-File: Just copy paste it into a file "acle5v1.txt" The objective of this code below is to check for upper case characters and to convert it to lower case and also to remove all punctuations so that these words are taken for further processing for word alignment #include<iostrea> #include<fstream> #include<ctype.h> #include<cstring> using namespace std; ifstream fin2("acle5v1.txt"); ofstream fin3("acle5v1_op.txt"); ofstream fin4("chkcharadded.txt"); ofstream fin5("chkcharntadded.txt"); ofstream fin6("chkprintchar.txt"); ofstream fin7("chknonasci.txt"); ofstream fin8("nonprinchar.txt"); int main() { char ch,ch1; fin2.seekg(0); fin3.seekp(0); int flag = 0; while(!fin2.eof()) { ch1=ch; fin2.get(ch); if (isprint(ch))// if the character is printable flag = 1; if(flag) { fin6<<"Printable character:\t"<<ch<<"\t"<<(int)ch<<endl; flag = 0; } else { fin8<<"Non printable character caught:\t"<<ch<<"\t"<<int(ch)<<endl; } if( isalnum(ch) || ch == '@' || ch == ' ' )// checks for alpha numeric characters { fin4<<"char added: "<<ch<<"\tits ascii value: "<<int(ch)<<endl; if(isupper(ch)) { //tolower(ch); fin3<<(char)tolower(ch); } else { fin3<<ch; } } else if( ( ch=='\t' || ch=='.' || ch==',' || ch=='#' || ch=='?' || ch=='!' || ch=='"' || ch != ';' || ch != ':') && ch1 != ' ' ) { fin3<<' '; } else if( (ch=='\t' || ch=='.' || ch==',' || ch=='#' || ch=='?' || ch=='!' || ch=='"' || ch != ';' || ch != ':') && ch1 == ' ' ) { //fin3<<" '; } else if( !(int(ch)>=0 && int(ch)<=127) ) { fin5<<"Char of ascii within range not added: "<<ch<<"\tits ascii value: "<<int(ch)<<endl; } else { fin7<<"Non ascii character caught(could be a -ve value also)\t"<<ch<<int(ch)<<endl; } } return 0; } I have a similar code as the above written in python which gives me an otput which is again not readable and not editable The code in python looks like this: #!/usr/bin/python # -*- coding: UTF-8 -*- import sys input_file=sys.argv[1] output_file=sys.argv[2] list1=[] f=open(input_file) for line in f: line=line.strip() #line=line.rstrip('.') line=line.replace('.','') line=line.replace(',','') line=line.replace('#','') line=line.replace('?','') line=line.replace('!','') line=line.replace('"','') line=line.replace('?','') line=line.replace('|','') line = line.lower() list1.append(line) f.close() f1=open(output_file,'w') f1.write(' '.join(list1)) f1.close() the file takes ip and op at runtime.. as: python punc_remover.py acle5v1.txt acle5v1_op.txt The output of this file is in "acle5v1_op.txt" now after processing this particular output file is needed for further processing. This particular file "aclee5v1_op.txt" is the UNREADABLE Aand UNEDITABLE File that I am not being able to use for further processing. I need this for Word alignment in NLP. I tried readin this output with the following program #include<iostream> #include<fstream> using namespace std; ifstream fin1("acle5v1_op.txt"); ofstream fout1("chckread_acle5v1_op.txt"); ofstream fout2("chcknotread_acle5v1_op.txt"); int main() { char ch; int flag = 0; long int r = 0; long int nr = 0; while(!(fin1)) { fin1.get(ch); if(ch) { flag = 1; } if(flag) { fout1<<ch; flag = 0; r++; } else { fout2<<"Char not been able to be read from source file\n"; nr++; } } cout<<"Number of characters able to be read: "<<r; cout<<endl<<"Number of characters not been able to be read: "<<nr; return 0; } which prints the character if its readable and if not it doesn't print them but I observed the output of both the file is blank thus I could draw a conclusion that this file "acle5v1_op.txt" is UNREADABLE AND UNEDITABLE. Could you please help me on how to deal with this problem.. To tell you a bit about the statistics wrt the original input file "acle5v1.txt" file it has around 3441 lines in it and around 3 million characters in it. Keeping in mind the number of characters in the file you editor might/might not be able to manage to open the file.. I was able to open the file in gedit of Fedora 10 which I am currently using .. This is just to notify you that opening with a particular editor was not actually an issue at least in my case... Can I use scripting languages like Python and Perl to deal with this problem if Yes how? could please be specific on that regard as I am a novice to Perl and Python. Or could you please tell me how do I solve this problem using C++ itself.. Thank you...:) I am really looking forward to some help or guidance on how to go about this problem....

    Hello, My question is how do i put these session variables into a array? I have tried countless ways but none of them work. Not really sure what to put in a array and what no and how to adress them. Currently when i fill in the form the data gets displayed in a table.

  • Query on simple C++ threadpool implementation

    - by ticketman
    Stackoverflow has been a tremendous help to me and I'd to give something back to the community. I have been implementing a simple threadpool using the tinythread C++ portable thread library, using what I have learnt from Stackoverflow. I am new to thread programming, so not that comfortable with mutexes, etc. I have a question best asked after presenting the code (which runs quite well under Linux): // ThreadPool.h class ThreadPool { public: ThreadPool(); ~ThreadPool(); // Creates a pool of threads and gets them ready to be used void CreateThreads(int numOfThreads); // Assigns a job to a thread in the pool, but doesn't start the job // Each SubmitJob call will use up one thread of the pool. // This operation can only be undone by calling StartJobs and // then waiting for the jobs to complete. On completion, // new jobs may be submitted. void SubmitJob( void (*workFunc)(void *), void *workData ); // Begins execution of all the jobs in the pool. void StartJobs(); // Waits until all jobs have completed. // The wait will block the caller. // On completion, new jobs may be submitted. void WaitForJobsToComplete(); private: enum typeOfWorkEnum { e_work, e_quit }; class ThreadData { public: bool ready; // thread has been created and is ready for work bool haveWorkToDo; typeOfWorkEnum typeOfWork; // Pointer to the work function each thread has to call. void (*workFunc)(void *); // Pointer to work data void *workData; ThreadData() : ready(false), haveWorkToDo(false) { }; }; struct ThreadArgStruct { ThreadPool *threadPoolInstance; int threadId; }; // Data for each thread ThreadData *m_ThreadData; ThreadPool(ThreadPool const&); // copy ctor hidden ThreadPool& operator=(ThreadPool const&); // assign op. hidden // Static function that provides the function pointer that a thread can call // By including the ThreadPool instance in the void * parameter, // we can use it to access other data and methods in the ThreadPool instance. static void ThreadFuncWrapper(void *arg) { ThreadArgStruct *threadArg = static_cast<ThreadArgStruct *>(arg); threadArg->threadPoolInstance->ThreadFunc(threadArg->threadId); } // The function each thread calls void ThreadFunc( int threadId ); // Called by the thread pool destructor void DestroyThreadPool(); // Total number of threads available // (fixed on creation of thread pool) int m_numOfThreads; int m_NumOfThreadsDoingWork; int m_NumOfThreadsGivenJobs; // List of threads std::vector<tthread::thread *> m_ThreadList; // Condition variable to signal each thread has been created and executing tthread::mutex m_ThreadReady_mutex;

int terms = sums->inputVal; double sum; for(int i=1; i<terms; i++) sum += 1.0/( double(i)*double(i) ); sums->outputVal = sum; } int main(int argc, char** argv) { int numThreads = 10; // Create pool ThreadPool threadPool; threadPool.CreateThreads(numThreads); // Create thread workspace CalculationDataStruct sums[numThreads]; // Set up jobs for(int i=0; i<numThreads; i++) { sums[i].inputVal = 3000*(i+1); threadPool.SubmitJob(LongCalculation, &sums[i]);

return 0; } Question: In the ThreadPool::ThreadFunc method, would better performance be obtained if the following if statement if(NumOfThreadsDoingWork == 0) was included? Also, I'd be grateful of criticisms and ways to improve the code. At the same time, I hope the code is of use to others.

  • how can i have a working dropdownlist with links from a csv in php

    - by Mark Dekker
    I have a website that loads a CSV, divides it into parts, and shows these parts. There are 7 parts, and since it is for a music store it is sliced like this: the name of the product the subname the price the stock in one shop the stock of the other shop the group name the brandname What i have now is that it shows 12 products on 1 page, with a next and previous link on top of the page. The pages are made with the group name, every group has it's own page, so you have a drums page, guitar page, speaker page. That all works great. What i programmed in there is a dropdownlist, it drops down a list of brandnames, which should narrow the search for a person who is looking at the products. Problem is right now, that the dropdown menu works, i see the brands, but they are NONE clickable, only the brands that are currently on the page are shown, so NOT all the brands from that group are shown, only the 12 that are currently showing, when you press next, it shows 12 more brands, but i want them to be shown right on the start. And the third problem is, when it is showing the brands, it shows them double or triple, depending on how many products have the same brand. Is there a way what i want, with this code as a basis ? <html> <body bgcolor=#E2E965 link=black vlink=black alink=black text=#D5DF23> <style type="text/css"> #nav, #nav ul { padding: 0; margin: 0; list-style: none; } #nav li { float: left; width: 120px; } #nav ul { position: absolute; width: 120px; left: -1000px; } #nav li:hover ul { left: auto; } <!-- a {text-decoration:none} //--> body { scrollbar-arrow-color: #E2E965; scrollbar-face-color: #D7182A; scrollbar-highlight-color: #000000; scrollbar-3dlight-color: #D6DF23; scrollbar-shadow-color: #00000; scrollbar-darkshadow-color: #00000; scrollbar-track-color: #D6DF23; } input:link {text-decoration: none; color: #E2E965;} input:visited {text-decoration: none; color: #E2E965;} input:active {text-decoration: none; color: #E2E965;} .spacer_black { margin: 0px; padding: 0px; border: 5px; height: 2px; width: 100%; line-height: 0px; font-size: 0px; background-color: #000000;} </style> <table width=800 border=0><td> </html> <?PHP $offset = isset($_GET['offset'])?$_GET['offset']:0; $LinesToDisplay = 12; $row = $offset + $LinesToDisplay; $row2 = $offset - $LinesToDisplay; $file_handle = fopen("web.txt", "rb"); error_reporting( E_ALL ); // DEBUGGING $SelectArray=array(); while ((($parts = fgetcsv($file_handle,4096,"|")) !== FALSE) && ($LinesToDisplay > 0) && (!feof($file_handle))) { //new code //skip first $offset lines $num = count($parts[6]); $SelectArray[]=$parts[6]; if ($parts[5] == 9999) { if ($offset-- > 0) {continue;} $parts[0] = ucwords(strtolower($parts[0])); $parts[1] = ucwords(strtolower($parts[1])); ?> <td> <?php echo "<table BACKGROUND='background.jpg' border=0 width=250><td width='243' height='105'>"; echo "<font size=-1 face='helvetica' color=#812990><b>$parts[0]</b></font>"; echo "<i>"; ?> <html> <div onMouseOver="this.style.color = 'black';" onMouseOut="this.style.color = '#D5DF23';"> </html><?php echo "<font size=2>-$parts[1]</font>"; echo "</div></i>"; ?><html><a href="#" title="Koop nu de <?php echo $parts[0]; ?>" onClick="window.open('form.php?p=<?php echo urlencode($parts[0]); ?>','popuppage','width=400,height=400,top=250,left=250,resizable=0,statusbar=0,titlebar=yes,toolbar=no,scrollbars=no,location=no,directories=no');"> <div><img src='ster.jpg' border=0 width='46' align='right'></a> <a href="#"><img src='envelope.jpg' border=0 width='46' align='right'title="Heeft u een vraag over <?php echo $parts[0]; ?>" onClick="window.open('vraag.php?p=<?php echo urlencode($parts[0]); ?>','popuppage','width=400,height=400,top=250,left=250,resizable=0,statusbar=0,titlebar=yes,toolbar=no,scrollbars=no,location=no,directories=no');"> <div></a> <TABLE BORDER='0' cellpadding='0' CELLSPACING='0'> <TR> <TD WIDTH='70' HEIGHT='20' BACKGROUND='pricebackground.jpg' VALIGN='bottom'> <center> <font size=2 color=white face='helvetica'> <b></html> <?php echo "€ $parts[2]"; ?> </b> </td> </tr> </table> <?php echo "<b><font size=3 color=#D7182A>Op Voorraad In:<br></font>"; echo ("<font color=black> Amsterdam </font>"); if ( $parts[3] >= 1 ) echo ("<IMG SRC =green.gif>").""; if ( $parts[3] <= 0 ) echo ("<IMG SRC =red.gif>").""; echo ("<font color=black> Utrecht </font>"); if ( $parts[4] >= 1 ) echo ("<IMG SRC =green.gif>")."</td></table></b><p style='margin:9px;'>"; if ( $parts[4] <= 0 ) echo ("<IMG SRC =red.gif>")."</td></table></b><p style='margin:9px;'>"; $LinesToDisplay--; if ($LinesToDisplay/3==intval($LinesToDisplay/3)) { echo "<tr><td>"; } }} fclose($file_handle); ?> <tr align=right> <select style="background-color: #FFFFFF; color: #000000; font-family: Arial; font-weight: none; font-size: 12; width: 150px; "> <?php $i=1; foreach ($SelectArray as $val){ echo "<option value=\"$i\">$val</option>\n"; $i++; } ?> </select> <font color=black><body alink=black vlink=black link=black text=black> <center><a href="occasiona.php?offset=<?php echo $row2; ?>" align=center>&laquo; previous</a> || <a href="occasiona.php?offset=<?php echo $row; ?>">next &raquo;</a></table></html>

  • Fitting an Image to Screen on Rotation iPhone / iPad ?

    - by user356937
    I have been playing around with one of the iPhone examples from Apple' web site (ScrollViewSuite) . I am trying to tweak it a bit so that when I rotate the the iPad the image will fit into the screen in landscape mode vertical. I have been successful in getting the image to rotate, but the image is larger than the height of the landscape screen, so the bottom is below the screen. I would like to image to scale to the height of the landscape screen. I have been playing around with various autoSizingMask attributes without success. The imageView is called "zoomView" this is the actual image which loads into a scrollView called imageScrollView. I am trying to achieve the screen to rotate and look like this.... olsonvox.com/photos/correct.png However, this is what My screen is looking like. olsonvox.com/photos/incorrect.png I would really appreciate some advice or guidance.

  • Having an issue with overwriting an element of a file correctly (numeric)

    - by IngeniousHax
    This is an ATM style program, but currently it doesn't do exactly what I need it to do... I need to get the current balance, and when money is transferred from either checking or savings, it should add it to checking and subtract it from savings. which is does, but not correctly... Input example -=[ Funds Transfer ]=- -=[ Savings to Checking ]=- Account Name: nomadic Amount to transfer: $400 New Balance in Checking: $900 // original was 500 New Balance in Savings: $7.7068e+012 // this should now be 1100...
