• CSV file read fail (PHP )

  - by user1020069

  I am trying to read a csv file (delimited by commas) but unfortunately, it isn't responding as it ought to. I am not so sure what I am doing wrong here, but I'll paste out the contents of the code and the CSV file both : $row = 0; if($handle = fopen("SampleQuizData.csv","r") !== FALSE) { // WORKS UNTIL HERE, SO FILE IS BEING READ while(!feof(handle)){ $line = fgetcsv($handle, 1024, ",") ; echo $line[2]; // DOES NOT WORK } } And the CSV file is (the emails and names have been changed here to protect the identities of the users) parijat,something,[email protected] matthew,durp, [email protected] steve,vai,[email protected] rajni,kanth,[email protected]

• simple modification results in error

  - by lgwest

  When I tried to do a simple modification of the "hello android" program that eclipse adt plugin generates I get error and can't get the program to run again even if I restore the file to its original contents. The modification was that I changed a string in strings.xml. the line was: <string name="app_name">Todo List</string> and the app was runnable, then I changed it to <string name="app_name">Todo List1</string> and it was an error: [2010-04-21 23:18:03 - Todo_list] Error in an XML file: aborting build. And a new empty file also showed up called: strings.out.xml And then I can't get the prrogram back into runnable state even if I delete the empyt file and restore the original line, I'm a confused beginner of java, android and eclipse.

• Forcing A Postback Asp.Net

  - by Nick LaMarca

  Please take a look at the following click event... Protected Sub btnDownloadEmpl_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDownloadEmpl.Click Dim emplTable As DataTable = SiteAccess.DownloadEmployee_H() Dim d As String = Format(Date.Now, "d") Dim ad() As String = d.Split("/") Dim fd As String = ad(0) & ad(1) Dim fn As String = "E_" & fd & ".csv" Response.ContentType = "text/csv" Response.AddHeader("Content-Disposition", "attachment; filename=" & fn) CreateCSVFile(emplTable, Response.Output) Response.Flush() Response.End() lblEmpl.Visible = True End Sub This code simply exports data from a datatable to a csv file. The problem here is lblEmpl.Visible=true never gets hit because this code doesnt cause a postback to the server. Even if I put the line of code lblEmpl.Visible=true at the top of the click event the line executes fine, but the page is never updated. How can I fix this?

• Use a cat + grep as an included source in bash

  - by Andrew

  I'm on a shared webhost where I don't have permission to edit the global bash configuration file at /ect/bashrc. Unfortunately there is one line in the global file, mesg y, which puts the terminal in tty mode and makes scp and similar commands unavailable. My local ~./bashrc includes the global file as a source, like so: # Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi My current workaround uses cat and grep to output the global file, sans offending line, into a local file and use that as a source. # Source global definitions if [ -f /etc/bashrc ]; then cat /etc/bashrc | grep -v mesg > ~/.bash_global . ~/.bash_global fi Is there a way to do include a grokked file like this without the intermediate step of creating an actual file? Something like this? . cat /etc/bashrc | grep -v mesg > ~/.bash_global

• Vertically align UILabel

  - by Ashish Agarwal

  I am trying to vertically align the text in the UILabel view of my app. The problem is that I want the text to be vertically aligned to the top and the size of the label to be 280 x 150. I am only able to achieve one of these 2 things. If I remove the line [myLabel sizeToFit]; then the alignment of the text is alright but the size is messed up. But if I add the above line, then the alignment is messed up but the size is alright. How do I fix this problem. I've added the code below - CGRect labelFrame = CGRectMake(22, 50, 280, 150); UILabel *myLabel = [[UILabel alloc] initWithFrame:labelFrame]; [myLabel setText:finalRecipe]; [myLabel setBackgroundColor: [UIColor lightGrayColor]]; [myLabel setNumberOfLines:0]; [myLabel sizeToFit]; [self.view addSubview:myLabel];

• Exact cin equivalent function in python

  - by gkt.pro

  Suppose user enter this string at terminal 123 456 456 //then hit enter How do I scan these three (could be more) numbers in different variables in python Could be something like this: for i in range(1,n) m[i]=#WHAT FUNCTION SHOULD I PUT HERE In c++ we can easily use cin>>m[i] inside above loop to scan the variables. If i use input() or raw_input() , they would scan whole line in single variable.

• How to search for a string including spaces in Objective C?

  - by AlexCu

  I have a real basic command-line program, in Objective-C, that searches for user inputed information. Unfourtunately, the code will only read the first word in series of words that the user enters. For example, if the user enters in "Apples are great", only "Apples" is kept (and hence searched later on), excluding the "are great" part of the sentence. Here's what I have so far: char enteredQuery [128]; // array 'name' to hold the scanf string NSString *searchQuery; // ending NSString to hold and compare the user inputed data NSLog(@"Enter search query:"); scanf("%s", enteredQuery); //will read the next line searchQuery = [NSString stringWithCString: enteredQuery encoding: NSASCIIStringEncoding]; //converts scanf data into a NSString type I know it's got to do with me using scanf or the character-encoder conversion, but I can't seem to figure it out. Any help in solving the problem is very appreciated! Thanks.

• Transferring binary file from web server to client

  - by Yan Cheng CHEOK

  Usually, when I want to transfer a web server text file to client, here is what I did import cgi print "Content-Type: text/plain" print "Content-Disposition: attachment; filename=TEST.txt" print filename = "C:\\TEST.TXT" f = open(filename, 'r') for line in f: print line Works very fine for ANSI file. However, say, I have a binary file a.exe (This file is in web server secret path, and user shall not have direct access to that directory path). I wish to use the similar method to transfer. How I can do so? What content-type I should use? Using print seems to have corrupted content received at client side. What is the correct method?

• Non-object when adding code into html

  - by Luke

  Hello. I am getting the following error: Fatal error: Call to a member function error() on a non-object in /home/gamepla3/public_html/football/result.php on line 177 The line for this is <?php echo $form->error("homescore"); ?> I'm failing to see how this could be the case? The thing worked fine before I added working code into my html document so it looked better. Now I can't get it working?? EDIT. When the code is not within HTML, it works fine. Once I have it within the HTML, it throws back an error? Has anyone seen anything like this before?

• O(N log N) Complexity - Similar to linear?

  - by gav

  Hey All, So I think I'm going to get buried for asking such a trivial but I'm a little confused about something. I have implemented quicksort in Java and C and I was doing some basic comparissons. The graph came out as two straight lines, with the C being 4ms faster than the Java counterpart over 100,000 random integers. The code for my tests can be found here; android-benchmarks I wasn't sure what an (n log n) line would look like but I didn't think it would be straight. I just wanted to check that this is the expected result and that I shouldn't try to find an error in my code. I stuck the formula into excel and for base 10 it seems to be a straight line with a kink at the start. Is this because the difference between log(n) and log(n+1) increases linearly? Thanks, Gav

• OpenGL index buffer object with additional data

  - by muksie

  I have a large set of lines, which I render from a vertex buffer object using glMultiDrawArrays(GL_LINE_STRIP, ...); This works perfectly well. Now I have lots of vertex pairs which I also have to visualize. Every pair consists of two vertices on two different lines, and the distance between the vertices is small. However, I like to have the ability to draw a line between all vertex pairs with a distance less than a certain value. What I like to have is something like a buffer object with the following structure: i1, j1, r1, i2, j2, r2, i3, j3, r3, ... where the i's and j's are indices pointing to vertices and the r's are the distances between those vertices. Thus every vertex pair is stored as a (i, j, r) tuple. Then I like to have a (vertex) shader which only draws the vertex pairs with r < SOME_VALUE as a line. So my question is, what is the best way to achieve this?

• Compiling C Source with Makefile in Windows

  - by humoeba

  I'm trying to compile a downloaded program in Windows. The program is usually run in Linux, but is programmed to also run in Windows (the code has #if defined(_WIN32)'s in it, and claims to work with borland free tools). When I try to use make from the command line, it tells me "Incorrect command line argument: -C". In the makefile, there are many lines that say "make -C" followed by a directory name. Does this syntax not work in Windows? What is a correct way to do this? Is there any way to compile this for native use in Windows with this makefile?

• C# Closing a form during a constructor

  - by pm_2

  Is it possible to close a form while the constructor is executing (or simply to stop it showing at this stage)? I have the following code: public partial class MyForm : Form { public MyForm() { if (MyFunc()) { this.Close(); } } } Which errors in Main(), here: static void Main() { ... // Following line errors Application.Run(new MyForm()); } I’ve tried checking the result of MyForm like this: static void Main() { ... MyForm frm = new MyForm(); if (frm != null) { // Following line errors Application.Run(frm); } } But that doesn’t seem to help. Can anyone tell me a way around this, please? Maybe a way to check the form to see if it still exists?

• Visual Studio 2005 - strange characters rendered for ANSI text

  - by Apogee

  Hi all, Has anyone seen this odd text rendering issue in VS2005 before? The first line of using statements actually says "using System;". If I copy the line as it is displayed and paste into notepad, the text appears correctly, so clearly the character codes are correct. In addition, the solution compiles and runs correctly. I was thinking it might be due to ClearCase using a different character encoding as all the solutions we're using were freshly checked-out yesterday on to a new build machine, but this is only happening in 2 of our ~30 solutions. Incidentally the same .cs files when opened in VS2008 render correctly on this machine, could this be a corruption in VS2005?

• How can I use gtkmm with MinGW (g++) without MSYS?

  - by paycity

  Hello stackoverflow members, How can I use gtkmm with MinGW (g++) without MSYS? Here is the story of my problem: I installed MinGW offline with all required packages (full install). I installed Apache Server and I copied all .tar.gz files and I created a website called sourceforge.org [localhost] and I installed automatically MinGW on Windows XP. After, I set the PATH variables. After, I installed gtkmm for MinGW (g++). I tried to compile a simple window with gtkmm + MinGW, but it does not work. I use this command line: g++ simple.cc -o simple pkg-config gtkmm-2.4 --cflags --libs After, I installed MSYS and I can compile simple.cc with MSYS, using this command line: g++ simple.cc -o simple pkg-config gtkmm-2.4 --cflags --libs My problem: I want to compile simple.cc without MSYS. I want compile my simple.cc with cmd.exe - It's possbile? If, yes. How? Thank you for reading my message. Any help is appreciated.

• Mod_rewrite works on local, not on remote, version?

  - by TylerT

  I have this site. Let's call it htp://www.mysite.com I have a rewrite rule to change htp://www.mysite.com/?q=words%20etc/0/10 into http://www.mysite.com/words%20etc/0/10 (or http://www.mysite.com//0/10 or http://www.mysite.com/0/10) .htaccess:ErrorDocument 404 htp://www.mysite.com/404.html options +FollowSymlinks rewriteEngine on rewriteCond %{REQUEST_URI} !-f rewriteCond %{REQUEST_URI} !-d rewriteCond %{REQUEST_URI} !index\.php rewriteRule ^/?([^/]+?)?/?([0-9]+?)/([0-9]+?)$ index.php/%{THE_REQUEST} [NC] Now, this works on my local apache 2.2.11 server, no errors. However on my host's apache 1.3.41 server, I get the following error: [Sat Mar 5 21:42:14 2011] [alert] [client [ip]] /home/_/public_html/mysite.com/.htaccess: RewriteRule: cannot compile regular expression '^/?([^/]+?)?/?([0-9]+?)/([0-9]+?)$'\n I imagine it's something quirky about the apache version as other sites on this host use mod_rewrite without a hitch. I've tried removing the +followSymlinks line, even the rewrite engine line. I haven't tried removing the conditions cause I don't think I should have to, I'm probably wrong.

• How to build a widget for my website

  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

• C++ vector of strings, pointers to functions, and the resulting frustration.

  - by Kyle

  So I am a first year computer science student, for on of my final projects, I need to write a program that takes a vector of strings, and applies various functions to these. Unfortunately, I am really confused on how to use pointer to pass the vector from function to function. Below is some sample code to give an idea of what I am talking about. I also get an error message when I try to deference any pointer. thanks. #include <iostream> #include <cstdlib> #include <vector> #include <string> using namespace std; vector<string>::pointer function_1(vector<string>::pointer ptr); void function_2(vector<string>::pointer ptr); int main() { vector<string>::pointer ptr; vector<string> svector; ptr = &svector[0]; function_1(ptr); function_2(ptr); } vector<string>::pointer function_1(vector<string>::pointer ptr) { string line; for(int i = 0; i < 10; i++) { cout << "enter some input ! \n"; // i need to be able to pass a reference of the vector getline(cin, line); // through various functions, and have the results *ptr.pushback(line); // reflectedin main(). But I cannot use member functions } // of vector with a deferenced pointer. return(ptr); } void function_2(vector<string>::pointer ptr) { for(int i = 0; i < 10; i++) { cout << *ptr[i] << endl; } }

• Textmate newbie question: how to indent CSS

  - by AP257

  New to TextMate and can't find the answer in the documentation. I've saved an empty file as CSS and the 'active bundle' is showing as CSS, at the bottom of the screen. I've then pasted in a bunch of CSS from elsewhere (a minified page). However, it's all pasted in as a single line. How can I indent it to look like 'proper' CSS, using TextMate? Text + Indent just indents the whole line by a single tab. thanks!
