  • Easy HTTPS to PHP script

    - by Tom
    Hi, here is my scenario: I have a website with php, mySQL. I have a software application that has a login screen and sends usernames and passwords over the web by http: public String GetWebPageSource(String pURL) { try { byte[] vReceivedBytes = null; using (System.Net.WebClient vWebClient = new System.Net.WebClient()) { vReceivedBytes = vWebClient.DownloadData(pURL); } int vBomLen = 3; byte[] vStrippedBytes = new byte[vReceivedBytes.Length - vBomLen]; Array.Copy(vReceivedBytes, vBomLen, vStrippedBytes, 0, vReceivedBytes.Length - vBomLen); return System.Text.Encoding.UTF8.GetString(vStrippedBytes); } catch (Exception e) { Console.WriteLine(e.Message); return null; } } So to send a username and password I would write: GetWebPageSource("http://mywebsite.com/Login.php?username=stackoverflow&password=iscool") and the php file would spit out some text saying whether the password is accepted or denied. However this is NOT secure. So I want to make it secure... https. How easy is it to integrate https? How much will the code change? How much do I have to handle? What is transparent to me. Do I have to check if a cookie already exists and if not write the methods for authentication or is there librarys already provided that will do it for me?

  • What are the benefits of a classical structure over a prototyple one?

    - by Rixius
    I have only recently started programming significantly, and being completely self-taught, I unfortunately don't have the benefits of a detailed Computer science course. I've been reading a lot about JavaScript lately, and I'm trying to find the benefit in classes over the prototype nature of JavaScript. The question seems to be drawn down the middle of which one is better, and I want to see the classical side of it. When I look at the prototype example: var inst_a = { "X": 123, "Y": 321, add: function () { return this.X+this.Y; } }; document.write(inst_a.add()); And then the classical version function A(x,y){ this.X = x; this.Y = y; this.add = function(){ return this.X+this.Y; }; }; var inst_a = new A(123,321); document.write(inst_a.add()); I begun thinking about this because I'm looking at the new ecmascript revision 5 and a lot of people seem up in arms that they didn't add a Class system.

  • How to deal with multiple screensizes + dynamic controls in Android?

    - by chobo2
    Hi I am learning how to program on Android phone. However I am unsure how to make my application work for the different screen sizes and resolutions. I read the tutorial on the android site and still unsure how to do it. First I know there are different files so could make a layout for each of the sizes but my problem is most of the screen needs to be dynamically created so there would not be much to put in these files. So I am not sure how to android to re size dynamic controls based on the screen size. I have also read it is bad practice to make controls in anything but the xml file as it separates view logic and programming logic. However they never talk about if you need to make these controls dynamically what you should do. So is there some other way to do it that is considered good practice?

  • Sending an HTTP POST request through the android emulator doesn't work

    - by Sotirios Delimanolis
    I'm running a tomcat servlet on my local machine and an Android emulator with an app that makes a post request to the servlet. The code for the POST is below (without exceptions and the like): String strUrl = "http://10.0.2.2:8080/DeviceDiscoveryServer/server/devices/"; Device device = Device.getUniqueInstance(); urlParameters += URLEncoder.encode("user", "UTF-8") + "=" + URLEncoder.encode(device.getUser(), "UTF-8"); urlParameters += "&" + URLEncoder.encode("port", "UTF-8") + "=" + URLEncoder.encode(new Integer(Device.PORT).toString(), "UTF-8"); urlParameters += "&" + URLEncoder.encode("address", "UTF-8") + "=" + URLEncoder.encode(device.getAddress().getHostAddress(), "UTF-8"); URL url = new URL(strUrl); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setDoOutput(true); connection.setRequestMethod("POST"); OutputStreamWriter wr = new OutputStreamWriter(connection.getOutputStream()); wr.write(urlParameters); wr.flush(); wr.close(); Whenever this code is executed, the servlet isn't called. However if I change the type of the request to 'GET' and don't write anything to the outputstream, the servlet gets called and everything works fine. Am I just not making the POST correctly or is there some other error?

  • Learning Java and logic using debugger. Did I cheat?

    - by centr0
    After a break from coding in general, my way of thinking logically faded (as if it was there to begin with...). I'm no master programmer. Intermediate at best. I decided to see if i can write an algorithm to print out the fibonacci sequence in Java. I got really frustrated because it was something so simple, and used the debugger to see what was going on with my variables. solved it in less than a minute with the help of the debugger. Is this cheating? When I read code either from a book or someone else's, I now find that it takes me a little more time to understand. If the alghorithm is complex (to me) i end up writing notes as to whats going on in the loop. A primitive debugger if you will. When you other programmers read code, do you also need to write things down as to whats the code doing? Or are you a genius and and just retain it?

  • How i can fix the increasing order summation code?

    - by user2971559
    I want from the java to reads all numbers from the user as long as the number entered by user is bigger than the previous number. But i could write it for only positive numbers. How i can fix code below if all numbers included. If it is possible please write the solution for beginners because its my first year in computer science in college and I haven't learn a lot yet. import acm.program.*; public class IncreasingOrder extends ConsoleProgram { public void run() { int previousNumber = 0; int total = 0; int count = 0; while(true) { int n = readInt("Enter > "); if (n <= previousNumber) break; total += n; count++; previousNumber = n; } println("You have entered " + count + " numbers in increasing order."); println("Sum of these " + count + " numbers is " + total + "."); } }

  • Execute an external application as root - problem

    - by user598011
    Good morning: I'm trying to run an external application that needs to be executed as root. I have to read the lines from exit after the execution of this application but it says "permission denied", as if the its not been done correctly. I've been thinking over a time and I can not move forward. The code is as follows: process = Runtime.getRuntime().exec("su"); String[] command = {external application command}; process = Runtime.getRuntime().exec(comando); InputStream inputStream = process.getInputStream(); BufferedReader bufferedReader = null; try { bufferedReader = new BufferedReader(new InputStreamReader(inputStream),8192); String line = null; while ((line = bufferedReader.readLine()) != null) { System.out.println("read line:"+line ); } } catch (IOException ioe) { ioe.printStackTrace(); } process.waitFor(); Does anyone know why not let me run the command? Thanks.

  • TXT file not showing properly in Android

    - by narkelion
    I developed an app for Android, that loads some data from some .txt files I created. Until now, everything went fine. Today I updated these texts to add some stuff, and now Android comes out with this error in the LogCat: 06-06 23:16:03.925: W/System.err(7999): java.lang.NumberFormatException: Invalid int: "?72" It never happened before. If I read the txt from my computer, I can see that all seems in the right place. But if I read it from the Android editor, I see strange symbols (close to that 72). I don't know how to remove them, because I cannot see them on the pc!

  • How to get the number of unread gmail mails (on android)

    - by Lord Otori
    I've been trying to get the number of unread gmail mails with no luck. I've read Gmail.java and gmail4j both links taken out of this site from this question: Android - How can I find out how many unread email the user has? But still after having read all of that and a couple of other sites that talked about this particular subject my question remains: Q: How can I get the Gmail Unread Count? Sorry if it seams a bit insistent but I clearly lack the knowledge to find this out on my own from the source. PS: I would like to clarify that I want to do it without having to ask the user for credentials. Just 2 add some colors to the question let me show you the looks of my app.

  • Split string on first two colons

    - by Mark Miller
    I would like to split a column of strings on the first two colons, but not on any subsequent colons: my.data <- read.table(text=' my.string some.data 12:34:56:78 -100 87:65:43:21 -200 a4:b6:c8888 -300 11:bb:ccccc -400 uu:vv:ww:xx -500', header = TRUE) desired.result <- read.table(text=' my.string1 my.string2 my.string3 some.data 12 34 56:78 -100 87 65 43:21 -200 a4 b6 c8888 -300 11 bb ccccc -400 uu vv ww:xx -500', header = TRUE) I have searched extensively and the following question is the closest to my current dilemma: Split on first comma in string Thank you for any suggestions. I prefer to use base R.

  • Python, lambda, find minimum

    - by qba
    I have foreach function which calls specified function on every element which it contains. I want to get minimum from thise elements but I have no idea how to write lambda or function or even a class that would manage that. Thanks for every help. I use my foreach function like this: o.foreach( lambda i: i.call() ) or o.foreach( I.call ) I don't like to make a lists or other objects. I want to iterate trough it and find min. I manage to write a class that do the think but there should be some better solution than that: class Min: def __init__(self,i): self.i = i def get_min(self): return self.i def set_val(self,o): if o.val < self.i: self.i = o.val m = Min( xmin ) self.foreach( m.set_val ) xmin = m.get_min() Ok, so I suppose that my .foreach method is non-python idea. I should do my Class iterable because all your solutions are based on lists and then everything will become easier. In C# there would be no problem with lambda function like that, so I though that python is also that powerful.

  • Beginner Question ; About Prime Generation in "C" - What is wrong with my code ? -

    - by alorsoncode
    I'm a third year irregular CS student and ,i just realized that i have to start coding. I passed my coding classes with lower bound grades so that i haven't a good background in coding&programming. I'm trying to write a code that generates prime numbers between given upper and lower bounds. Not knowing C well, enforce me to write a rough code then go over it to solve. I can easily set up the logic for intended function but i probably create a wrong algorithm through several different ways. Here I share my last code, i intend to calculate that when a number gives remainder Zero , it should be it self and 1 , so that count==2; What is wrong with my implementation and with my solution generating style? I hope you will warm me up to programming world, i couldn't find enough motivation and courage to get deep into programming. Thanks in Advance :) Stdio and Math.h is Included int primegen(int down,int up) { int divisor,candidate,count=0,k; for(candidate=down;candidate<=up;candidate++) { for(divisor=1;divisor<=candidate;divisor++) { k=(candidate%divisor); } if (k==0) count++; if(count==2) { printf("%d\n", candidate); count=0; } else { continue; } } } int main() { primegen(3,15); return 0; }

  • [ask][php] find dynamic filename exist

    - by r4ccoon
    hi. i am writing a cache module in php. it tries to write a cache with a $string+timestamp as a filename. i dont have problem with writing the cache. the problem is i do a foreach loop to get the cache that i want. this is the logic that i use for getting the cache foreach ($filenames as $filename){ if(strstr($filename,$cachename)){//if found if(check_timestamp($filename,time())) display_cace($filename); break; } } but when it tries to get and read the cache, it slows the server down. imagine that i have 10000 cache file in a folder, and i need to check for every file in that cache folder. so how do you think the best way of doing this. here i explain again, because even me still dont understand my written question.. :D i write cache file with this format filename_timestamp.. e.g cache_function_random_news_191982899010 in a folder ./cache/ when i want to get the cache, i only pass "cache_function_random_news_" and check recursively on that folder. if i find something with that needle on a file name, display it, and break. but checking recursively on a 10000 files in a folder is not a good thing yeah? please give me your opinion ok, that would clarify more. thanks.

  • Writing a script for reading many .csv files with similar filenames

    - by wahalulu
    I have several .csv files with similar filenames except a numeric month (i.e. 03_data.csv, 04_data.csv, 05_data.csv, etc.) that I'd like to read into R. I have two questions: Is there a function in R similar to MATLAB's varname and assignin that will let me create/declare a variable name within a function or loop that will allow me to read the respective .csv file - i.e. 03_data.csv into 03_data data.frame, etc.? I want to write a quick loop to do this because the filenames are similar. As an alternative, is it better to create one dataframe with the first file and then append the rest using a for loop? How would I do that?

  • A 3-D grid of regularly spaced points

    - by Jack
    I want to create a list containing the 3-D coords of a grid of regularly spaced points, each as a 3-element tuple. I'm looking for advice on the most efficient way to do this. In C++ for instance, I simply loop over three nested loops, one for each coordinate. In Matlab, I would probably use the meshgrid function (which would do it in one command). I've read about meshgrid and mgrid in Python, and I've also read that using numpy's broadcasting rules is more efficient. It seems to me that using the zip function in combination with the numpy broadcast rules might be the most efficient way, but zip doesn't seem to be overloaded in numpy.

  • How to bring Webserive text into a Winform aplication

    - by CogentP
    I am working a Winform Application that needs to access a webservice to get some basic information. The webservice exists, and the following is a link that brings text. Which basically is the customer name in Json format. http://globalbox.com.py/api/getUSER.php?gb=3217 So, my point, i need to be able to read the name of the customer and put that into a string variable. How do I read this from Winforms? I have no idea how to go about doing this... please help. Visual Basic code would be better, or else C# will do. thanks in advance!!

  • Looking for an email/report templating engine with database backend - for end-users ...

    - by RizwanK
    We have a number of customers that we have to send monthly invoices too. Right now, I'm managing a codebase that does SQL queries against our customer database and billing database and places that data into emails - and sends it. I grow weary of maintaining this every time we want to include a new promotion or change our customer service phone numbers. So, I'm looking for a replacement to move more of this into the hands of those requesting the changes. In my ideal world, I need : A WYSIWYG (man, does anyone even say that anymore?) email editor that generates templates based upon the output from a Database Query. The ability to drag and drop various fields from the database query into the email template. Display of sample email results with the database query. Web application, preferably not requiring IIS. Involve as little code as possible for the end-user, but allow basic functionality (i.e. arrays/for loops) Either comes with it's own email delivery engine, or writes output in a way that I can easily write a Python script to deliver the email. Support for generic Database Connectors. (I need MSSQL and MySQL) F/OSS So ... can anyone suggest a project like this, or some tools that'd be useful for rolling my own? (My current alternative idea is using something like ERB or Tenjin, having them write the code, but not having live-preview for the editor would suck...)

  • Reading in MIPS external file so another file can use it?

    - by SkyWookie
    Hey all, I'm working on this final thing for my MIPS project and it's deceptively easy. I need to get a procedure (called feed) and let its main driver program use it by reading it in. I know that I'm supposed to use the call code 14 and .globl sym (I think) in order to feed it into the file and have it read it. I just need a basic tutorial or something, as I CANNOT find it on the Internet or in my book (just lists the call code, real helpful). Here's what I know: I need to use read, but I also need a file descriptor (don't know where to get it). I need to put the buffer in $a1 and the length in $a2. Well, that's about it. If there's any decent tutorial you could whip up or if there is one online that I don't see let me know please :). I just need a push in the right direction, I'm sure it can't be too difficult, just can't find any info on it!

  • C++ stringstream reads all zero's

    - by user69514
    I have a file which contains three integers per line. When I read the line I use a stringstream to separate the values, but it only reads the first value as it is. The other two are read as zero's. ifstream inputstream(filename.c_str()); if( inputstream.is_open() ){ string line; stringstream ss; while( getline(inputstream, line) ){ //check line and extract elements int id; double income; int members; ss.clear(); ss.str(line); ss >> id >> income >> members; In the case above, id is extracted correctly, but income, and members get assigned zero instead of the actual value.

  • Why can't I reserve 1,000,000,000 in my vector ?

    - by vipersnake005
    When I type in the foll. code, I get the output as 1073741823. #include <iostream> #include <vector> using namespace std; int main() { vector <int> v; cout<<v.max_size(); return 0; } However when I try to resize the vector to 1,000,000,000, by v.resize(1000000000); the program stops executing. How can I enable the program to allocate the required memory, when it seems that it should be able to? I am using MinGW in Windows 7. I have 2 GB RAM. Should it not be possible? In case it is not possible, can't I declare it as an array of integers and get away? BUt even that doesn't work. Another thing is that, suppose I would use a file(which can easily handle so much data ). How can I let it read and write and the same time. Using fstream file("file.txt', ios::out | ios::in ); doesn't create a file, in the first place. But supposing the file exists, I am unable to use to do reading and writing simultaneously. WHat I mean is this : Let the contents of the file be 111111 Then if I run : - #include <fstream> #include <iostream> using namespace std; int main() { fstream file("file.txt",ios:in|ios::out); char x; while( file>>x) { file<<'0'; } return 0; } Shouldn't the file's contents now be 101010 ? Read one character and then overwrite the next one with 0 ? Or incase the entire contents were read at once into some buffer, should there not be atleast one 0 in the file ? 1111110 ? But the contents remain unaltered. Please explain. Thank you.

  • Reading from a file into an array in c

    - by NaNa21
    My file contains a series of numbers (integer, float, integer, float ....), each written on a separate line. The numbers of columns are different from one line to another i.e. 1 2.45 3 1.75 5 3.45 7 2.55 9 3.25 6 1.75 4 3.55 6 2.55 9 2.45 The program should read the contents of the entire file and place the data into an array of type float with an entry for each line. Here is my basic solution, but this is only suitable if I have fixed no of columns. float Read(FILE *pFile) { char line[50]; char letter[5]; fi = fopen("file.txt", "r"); while (fgets(line,200,fi)!=NULL) { sscanf(line,"%f %f %f",&a[i], &a2[i],&a3[i]); printf("%2.0f %2.5f %2.0f\n",a[i],a2[i],a3[i]); } fclose(fi); return a[i]; } Please HELP.

  • PHP dynamic Page-level DocBlocks

    - by Obmerk Kronen
    I was wondering if there is a way to interact with the Page-level DocBlocks. My question is more specifically about wordpress plugin development, but this question has arised also in a non-wordpress environments. The reason is mainly the possibility to easily change VERSIONS and names throughout a large project with maybe a constant definition - but that will reflect also in the docblock.. The following example Docblock is from a wordpress plugin I write - /* Plugin Name: o99 Auxilary Functions v0.4.7 Plugin URI: http://www.myurl.com Description: some simple description that nobody reads. Version: 0.4.7 Author: my cool name Author URI: http://www.ok-alsouri.com */ Is there a way to transform it into : $ver = '0.4.7'; $uri = 'http://www.myurl.com'; $desc = 'some simple description that nobody reads.'; $mcn = 'my cool name'; etc.. etc.. /* Plugin Name: o99 Auxilary Functions ($ver) Plugin URI: ($uri) Description: ($desc) Version: ($ver) Author: ($mcn) Author URI: ($$uri) */ obviously for echo to work I would need to break the docblock itself, and I can not WRITE the docblock directly into it´s own file . In shorts : can I "generate" a docblock with php itself somehow (I would think that the answer is - "no" for the page itself.. But maybe I am wrong and someone has some neat hack :-) ) Is that even possible ?
