    - by simon
    HI ! I would like to compare values from a textbox with data from a table. I tried this code but i got the error that the input string was in the wrong format! code: string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=save.mdb"; try { database = new OleDbConnection(connectionString); database.Open(); string queryString = "SELECT zivila.naziv,users.user_name FROM (obroki_save " + " LEFT JOIN zivila ON zivila.ID=obroki_save.ID_zivila) " + " LEFT JOIN users ON users.ID=obroki_save.ID_uporabnika " + " WHERE users.ID='" +Convert.ToInt16(id.iDTextBox.Text)+"'"; loadDataGrid(queryString); } catch (Exception ex) { MessageBox.Show(ex.Message); return; }

  • jQuery async ajax query and returning value problem (scope, closure)

    - by glebovgin
    Hi. Code not working because of async query and variable scope problem. I can't understand how to solve this. Change to $.ajax method with async:false - not an option. I know about closures, but how I can implement it here - don't know. I've seen all topics here about closures in js and jQuery async problems - but still nothing. Help, please. Here is the code: var map = null; var marker; var cluster = null; function refreshMap() { var markers = []; var markerImage = new google.maps.MarkerImage('/images/image-1_32_t.png', new google.maps.Size(32, 32)); $.get('/get_users.php',{},function(data){ if(data.status == 'error') return false; var users = data.users; // here users.length = 1 - this is ok; for(var i in users) { //here I have every values from users - ok var latLng = new google.maps.LatLng(users[i].lat, users[i].lng); var mark = new google.maps.Marker({ position: latLng, icon: markerImage }); markers.push(mark); alert(markers.length); // length 1 } },'json'); alert(markers.length); // length 0 //if I have alert() above - I get result cluster = new MarkerClusterer(map, markers, { maxZoom: null, gridSize: null }); } Thanks.

  • How to create an ARGB_8888 pixel value?

    - by vidstige
    Say I want to create an array of pixel values to pass into the createBitmap method described here. I have three int values r, g, b in the range 0 - 0xff. How do I transform those into a opaque pixel p? Does the alpha channel go in the high byte or the low byte? I googled up the documentation but it only states that: Each pixel is stored on 4 bytes. Each channel (RGB and alpha for translucency) is stored with 8 bits of precision (256 possible values.) This configuration is very flexible and offers the best quality. It should be used whenever possible. So, how to write this method? int createPixel(int r, int g, int b) { retrurn ? }

  • delete common dictionaries in list based on a value

    - by pythoonatic
    How would I delete all corresponding dictionaries in a list of dictionaries based on one of the dictionaries having a character in it. data = [ { 'x' : 'a', 'y' : '1' }, { 'x' : 'a', 'y' : '1/1' }, { 'x' : 'a', 'y' : '2' }, { 'x' : 'b', 'y' : '1' }, { 'x' : 'b', 'y' : '1' }, { 'x' : 'b', 'y' : '1' }, ] For example, how would I delete all of the x = a due to one of the y in the x=a having a / in it? Based on the example data above, here is where I would like to get to: cleaneddata = [ { 'x' : 'b', 'y' : '1' }, { 'x' : 'b', 'y' : '1' }, { 'x' : 'b', 'y' : '1' }, ]

  • class classname(value); & class classname=value; difference when constructor is explicit

    - by Mahesh
    When constructor is explicit, it isn't used for implicit conversions. In the given snippet, constructor is marked as explicit. Then why in case foo obj1(10.25); it is working and in foo obj2=10.25; it isn't working ? #include <iostream> class foo { int x; public: explicit foo( int x ):x(x) {} }; int main() { foo obj(10.25); // Not an error. Why ? foo obj2 = 10.25; // Error getchar(); return 0; } error: error C2440: 'initializing' : cannot convert from 'double' to 'foo'

  • Perl: Value of response code in HTTP::Request

    - by lola
    Hi all, So, I am writing a code to get a document from the internet. The document size is around 200 KB. This is the code: !/usr/local/bin/perl -w use strict; use LWP::UserAgent; my $ua = LWP::UserAgent->new; my $url = "SOME URL"; my $req = HTTP::Request->new(GET => $url); my $res = $ua->request($req); if($res->is_success){ print $res->content ."\n"; } else{ print "Error: " . $res->status_line; } Now, the only problem is I can't mention what the URL is. However, the output is: "Error: 500 read timeout". When I checked the link externally, the data is being downloaded in under 5 seconds. I even changed the timeout to 1000s, but it still didn't work. How should I go about finding more information related to the response. The size of the file (around 200KB) is also not too great to warrant a read timeout. The server is also not a busy one, didn't give a problem whenever I checked the link on the browser. Thanks.

  • Multiple value array

    - by Ant..
    I am new to jScript and have written this code [which works perfectly]. Its purpose is to test that the term for the amount of loan is not exceeded. Can the process be consolidated into one array where you pass the loan amount which returns the term based on the range i.e. 6000 to 7000 = 96 function TestMaxTerm() { var LnAmt = 14000 //Testing Purposes var Term = 0 //Testing Purposes if (LnAmt > 0 && LnAmt <= 1000){Term = 0;} if (LnAmt > 1000 && LnAmt <= 2000){Term = 1;} if (LnAmt > 2000 && LnAmt <= 3000){Term = 2;} if (LnAmt > 3000 && LnAmt <= 4000){Term = 3;} if (LnAmt > 4000 && LnAmt <= 5000){Term = 4;} if (LnAmt > 5000 && LnAmt <= 6000){Term = 5;} if (LnAmt > 6000 && LnAmt <= 7000){Term = 6;} if (LnAmt > 7000 && LnAmt <= 8000){Term = 7;} if (LnAmt > 8000 && LnAmt <= 9000){Term = 8;} if (LnAmt > 9000 && LnAmt <= 10000){Term = 9;} if (LnAmt > 10000 && LnAmt <= 11000){Term = 10;} if (LnAmt > 11000 && LnAmt <= 12000){Term = 11;} if (LnAmt > 11000){Term = 12;} //Obtain Maximum Term for Loan Amount var MaxTerm = new Array(); MaxTerm[0] = 24; MaxTerm[1]=36; MaxTerm[2] = 48; MaxTerm[3] = 60; MaxTerm[5] = 72; MaxTerm[5]=84; MaxTerm[6] = 96; MaxTerm[7] = 108; MaxTerm[8] = 120; MaxTerm[9]=132; MaxTerm[10] = 164; MaxTerm[11] = 176; MaxTerm[12] = 420; var text = MaxTerm[Term]; alert(text); }

  • Reset JPA generated value between tests

    - by Rythmic
    I'm running spring + hibernate + JUnit with springJunit4runner and transactional set to default rollback I'm using in-memory derbydb as Database. Hibernate is used as a JPA Provider and I am successfully testing CRUD kinds of stuff. However, I have a problem with JPA and the behaviour of @GeneratedValue If I run one of my tests in isolation, two entitys are persisted with id 1 and 2. If i run the whole test suite the ids are instead 6 and 7. Spring does rollbacks just fine so there are only these two entitys in the database after addition and of course zero before. But behaviour of @GeneratedValue doesn't allow me to reliable findById unless I would return the Id from the dao.add(Entity e) //method I don't feel like doing that for the sake of testing, or is it a good practise to return the entity that was persisted so I should be doing it anyway?

  • Ruby hash value truthiness and symbols

    - by John Topley
    Could somebody please explain why the variable named foo remains true in the code below, even though it's set to false when the method is called? And why the symbol version behaves as expected? def test(options = {}) foo = options[:foo] || true bar = options[:bar] || :true puts "foo is #{foo}, bar is #{bar}" end >> test(:foo => false, :bar => :false) foo is true, bar is false I've only tried this using Ruby 1.8.7.
