• Design support for templated UserControl

  - by SaphuA

  Hello, I have created a real simple templated UserControl using the following tutorial: http://msdn.microsoft.com/en-us/library/36574bf6(VS.80).aspx I can now add this control to my mvc 2.0 application using: <components:Box BoxType="Help" Title="Content Title" runat="server"> <Content> <%: Html.TextBox("test") %> This is my awesome content!<br /> <b>Test</b> </Content> </components:Box> However, when I go to the designer, I get an exception: Type 'System.Web.UI.UserControl' does not have a public property named 'Content'. How can I fix this? I don't even need to use the drag-and-drop designer, just rendering the control will do fine. Thanks!

• Strange behavior: Dynamic expressions with RegExp Object in RegExp.match (Javascript)

  - by NeDark

  I have detect a strange behavior in regexps created with the RegExp object: With this code: var exp1 = /./; var exp2 = new RegExp('.'); ? var test1 = exp1.test('large\n\ntext..etc.'); var test2 = exp2.test('large\n\ntext..etc.'); ? var match1 = 'large\n\ntext..etc.'.match(exp1); var match2 = 'large\n\ntext..etc.'.match(exp2); ...the result is: test1 = true test2 = true ? match1 = 'l' (first match) match2 = null With the regexp maked with the regexp object from a string it finds nothing... Why does this happends? Thanks!!

• How do I dynamically name objects in Java?

  - by hatboysam

  Let's say I needed to make a series of String[] objects. I know that if i wanted to make a string array called "test" to hold 3 Strings I could do String[] test = new String[3]; But let's say I needed to make a series of these arrays and I wanted them to be named, 1,2, 3, 4, 5... etc. For however many I needed and I didn't know how many I'd need. How do I achieve a similar effect to this: for (int k=0; k=5; k++){ String[] k = new String[3]; } Which would created 5 string arrays named 1 through 5. Basically I want to be able to create array objects with a name detemined by some other function. Why can't I seem to do this? Am I just being stupid?

• What should be done first: Code reviews or Unit tests?

  - by goldenmean

  Hello, If a developer implements code for some module and wants to get it reviewed. What should be the order : *First unit test the module after designing test cases for the module, debugging and fixing the bugs and then give the modified code for peer code review (Pros- Code to be reviewed is 'clean' to a good extent. Reduces some avoidable review comments and rework. Cons- Developer might spend large time debugging/fixing a bug which could have pointed/anticipated in peer code reviews) Or *First do the code review with peers and then go for unit testing. What are your thoughts/experience on this? I believe this approach for unit testing, code reviewing should be programming language agnostic, but it would be interesting to know otherwise(if applicable) with specific examples. -AD

• Find/parse server-side <?abc?>-like tags in html document

  - by Iggyhopper

  I guess I need some regex help. I want to find all tags like <?abc?> so that I can replace it with whatever the results are for the code ran inside. I just need help regexing the tag/code string, not parsing the code inside :p. <b><?abc print 'test' ?></b> would result in <b>test</b> Edit: Not specifically but in general, matching (<?[chars] (code group) ?>)

• PHP Nested classes work... sort of?

  - by SeanJA

  So, if you try to do a nested class like this: //nestedtest.php class nestedTest{ function test(){ class E extends Exception{} throw new E; } } You will get an error Fatal error: Class declarations may not be nested in [...] but if you have a class in a separate file like so: //nestedtest2.php class nestedTest2{ function test(){ include('e.php'); throw new E; } } //e.php class E Extends Exception{} So, why does the second hacky way of doing it work, but the non-hacky way of doing it does not work?

• Cookie: ASP.NET SessionId Issue

  - by LB

  I have a load generator that appends a ASP.NET_SessionId to the Cookie when making a Soap test call from Machine A to Machine B. Cookie: ASP.NET_SessionId=gf0ouay24sdneiuicpiggn45; However, when I'm running the soap test hitting my local server it doesn't have an ASP.NET_Session variable in the cookie. Why is this happening? UPDATE: I'm getting this issue now on the server: Forms authentication failed for the request. Reason: The ticket supplied was invalid. I've followed this: http://msmvps.com/blogs/omar/archive/2006/08/20/108307.aspx But to no avail.

• how to compare between Doctrine & Propel in symfony

  - by Patrick

  I am in the early stages of rearchitecting my company's application. The app is currently running on symfony 1.2, and I used the default ORM at the time, Propel. Symfony has since updated to 1.4 and switched default ORM to Doctrine. From my understanding, each ORM excels at particular types of database structures. Is this true or is one far and away better than the other? Are there any good methods to test which ORM would be best in my situation in a test environment using my schema (i.e.- set up dual, identical sites and run tests)?

• PHP date function not accepting timezone change

  - by Pepper

  Hello, I've set up a quick little test to understand and debug timezones between mySQL and PHP. Here's the page: http://dev.feedingo.com/test_dates.php The dates are being created in mySQL using NOW() in a datetime field. The initial problem I was trying to figure out is what timezone mySQL is using and how to sync it up with PHP. But now there's an even weirder issue. In my test app, if you change your timezone, the first strtotime updates properly, but if you pass it into a date() function it doesn't change. This is how im setting the timezone based off the select box. $current_timezone = 'America/New_York'; if( isset( $_GET['timezone'] ) ) $current_timezone = $_GET['timezone']; date_default_timezone_set($current_timezone); Any ideas as to why the date() function isn't accepting the timezone changes? Thanks!

• Java-script object - get variable name

  - by Mikk

  Hi, To begin with, I'm not even sure, if it is the right way to do it. Let's say, i have script (jquery included) like this: foo = function() { this.bar = function() { alert('I\'m bar'); } this.test = function() { $('body').append('<a onclick="my_var.bar();">Click me</a>'); } this.test(); } var my_var = new foo(); Is there any way, i could make variable "my_var" dynamic inside function "foo". So I could do something like $('body').append('<a onclick="'+the_variable_which_im_assigned_to+'.bar();">Click me</a>'); Thank you

• Variable lenght arguments in log4cxx LOG4CXX_ macros

  - by Horacio

  I am using log4cxx in a big C++ project but I really don't like how log4cxx handles multiple variables when logging: LOG4CXX_DEBUG(logger, "test " << var1 << " and " << var3 " and .....) I prefer using printf like variable length arguments: LOG4CXX_DEBUG(logger, "test %d and %d", var1, var3) So I implemented this small wrapper on top of log4cxx #include <string.h> #include <stdio.h> #include <stdarg.h> #include <log4cxx/logger.h> #include "log4cxx/basicconfigurator.h" const char * log_format(const char *fmt, ...); #define MYLOG_TRACE(logger, fmt, ...) LOG4CXX_TRACE(logger, log_format(fmt, ## __VA_ARGS__)) #define MYLOG_DEBUG(logger, fmt, ...) LOG4CXX_DEBUG(logger, log_format(fmt, ## __VA_ARGS__)) #define MYLOG_INFO(logger, fmt, ...) LOG4CXX_INFO(logger, log_format(fmt, ## __VA_ARGS__)) #define MYLOG_WARN(logger, fmt, ...) LOG4CXX_WARN(logger, log_format(fmt, ## __VA_ARGS__)) #define MYLOG_ERROR(logger, fmt, ...) LOG4CXX_ERROR(logger, log_format(fmt, ## __VA_ARGS__)) #define MYLOG_FATAL(logger, fmt, ...) LOG4CXX_FATAL(logger, log_format(fmt, ## __VA_ARGS__)) static log4cxx::LoggerPtr logger(log4cxx::Logger::getRootLogger()); int main(int argc, char **argv) { log4cxx::BasicConfigurator::configure(); MYLOG_INFO(logger, "Start "); MYLOG_WARN(logger, log_format("In running this in %d threads safe?", 1000)); MYLOG_INFO(logger, "End "); return 0; } const char *log_format(const char *fmt, ...) { va_list va; static char formatted[1024]; va_start(va, fmt); vsprintf(formatted, 1024, fmt, va); va_end(va); return formatted; } And this works perfectly but I know using that static variable (formatted) can become problematic if I start using threads and each thread logging to the same place. I am no expert in log4cxx so I was wondering if the LOG4CXX macros are handling concurrent thread access automatically? or do I have to implement some sort of locking around the log_format method? something that I wan't to avoid due to performance implications. Also I would like to ask why if I replace the vsprintf inside the log_format method with vsnprintf (that is more secure) then I get nothing printed? To compile and test this program (in Ubuntu) use : g++ -o loggertest loggertest.cpp -llog4cxx

• Is there a way to catch a MOUSE_UP Event over a static textfield in Flash?

  - by Jovica Aleksic

  When the user presses the mouse, and releases it over a static textfield with selectable text, no MOUSE_UP event is fired - not on the stage and also nowhere else. I experienced this when using a scrollbar class on a movieclip with a nested static textfield. When the user drags the scroll handle and releases the mouse over the textfield, the dragging/scrolling is stuck. To test this, create a new AS3 fla file, place a static textfield somewhere, and put in some text. Make sure the selectable property is checked in the properties panel. Add this script to the timeline: import flash.events.* function down(event:Event):void { trace('down'); } function up(event:Event):void { trace('up'); } stage.addEventListener(MouseEvent.MOUSE_DOWN, down) stage.addEventListener(MouseEvent.MOUSE_UP, up) Now test the movie and click the mouse. You will notice that trace('up') will not occur when you release the mouse over the textfield.

• Do invariant assertions fit into C# programming?

  - by P.Brian.Mackey

  In the book coders at work, the author asks "How do you use invariants in your code". Please explain what this question means. I saw class invariants on wiki, but the example is in Java and I am not skilled enough in Java to relate this example to C#. .NET 4.0 introduces invariance, covariance, and contravariance and is well explained here. Invariance is so broad. The authors usage of the word seems unit test related. For those that read the book, what does the author mean? Are we talking about making an assumption and simply testing the validity after the unit test?

• PayPal testing without using Sandbox

  - by Webbo

  I am developing a website in PHP that accepts PayPal payments. It uses the IPN from PayPal and has a custom payment template etc etc. It all works great through the Sandbox server but when it comes to showing my client, I don't want to have to tell them to login to/create a Sandbox account, create a buyer account and make a payment - he hasn't got time for that and probably won't be able to do it. Therefore, my question is - is there any simple way that I can show my client the PayPal integration in "test mode" without him using the sandbox? I realise that I can set the transaction value to 0.01 and just test on the live PayPal server but that isn't an ideal solution. Cheers! Edit: Just to better explain what I mean, this is what my client sees when he first goes to checkout; As you can see, he has to login to his Sandbox account before then purchasing the item using the buyer email that he sets up. It's just confusing and totally non user-friendly.

• jquery calendarpicker callback pass querystring

  - by user577318

  Trying to use this CalendarPicker source and docs here: http://bugsvoice.com/applications/bugsVoice/site/test/calendarPickerDemo.jsp I need to be able to pass the date selected as query string variable of "searchdate" and reload page also updating current date for calendarPicker with querystring date on page reload. This is what I have so far: jQuery(document).ready(function() { var calendarPicker = jQuery("#calendarpicker").calendarPicker({ monthNames:["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"], dayNames: ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"], years:0, months:6, days:5, showDayArrows:true, callback:function(cal) { // Simple output to test calendar date change jQuery("#output").html("Selected date: " + cal.currentDate.getFullYear()+"-"+cal.currentDate.getMonth()+"-"+cal.currentDate.getDate() ); // Not working well since it also includes arrows from datepicker as selectors jQuery(".calDay").children().click(function() { window.location.href="mysite.com?searchdate="+cal.currentDate.getFullYear()+"-"+cal.currentDate.getMonth()+"-"+cal.currentDate.getDate(); }); } }); Any help greatly appreciated. Can this be done with ajax? I am attempting to update a table of events by datepicker.

I checked Control panel date and time setting and it is correctly set to London. Web server is IIS7 but I don't think that would affect anything? IN region and Language, location is set to United Kingdom and in Administrative (change system locale ) it is also correct as English (United Kingdom)

• PHP Moving mySQL Tree Node

  - by TK

  I am having trouble trying to move sub nodes or parent nodes up or down... not that good at math. CREATE TABLE IF NOT EXISTS `pages` ( page-id mediumint(8) unsigned NOT NULL AUTO_INCREMENT, page-left mediumint(8) unsigned NOT NULL, page-right smallint(8) unsigned NOT NULL, page-title text NOT NULL, page-content text NOT NULL, page-time int(11) unsigned NOT NULL, page-slug text NOT NULL, page-template text NOT NULL, page-parent mediumint(8) unsigned NOT NULL, page-type text NOT NULL, PRIMARY KEY (page-id) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 ; INSERT INTO pages (page-id, page-left, page-right, page-title, page-content, page-time, page-slug, page-template, page-parent, page-type) VALUES (17, 1, 6, '1', '', 0, 'PARENT', '', 0, ''), (18, 2, 5, '2', '', 0, 'SUB', '', 17, ''), (19, 3, 4, '3', '', 0, 'SUB-SUB', '', 18, ''), (20, 7, 8, '5', '', 0, 'TEST', '', 0, ''); As example how would I move TEST up above PARENT and say move SUB down below SUB-SUB by playing with the page-left/page-right IDs? Code is not required just help with the SQL concept or math for it, would help me understand how to move it better...

• Connection to DB2 in Python

  - by Mestika

  Hi, I'm trying to create a database connection in a python script to my DB2 database. When the connection is done I've to run some different SQL statements. I googled the problem and has read the ibm_db API (http://code.google.com/p/ibm-db/wiki/APIs) but just can't seem to get it right. Here is what I got so far: import sys import getopt import timeit import multiprocessing import random import os import re import ibm_db import time from string import maketrans query_str = None conn = ibm_db.pconnect("dsn=write","usrname","secret") query_stmt = ibm_db.prepare(conn, query_str) ibm_db.execute(query_stmt, "SELECT COUNT(*) FROM accounts") result = ibm_db.fetch_assoc() print result status = ibm_db.close(conn) but I get an error. I really tried everything (or, not everything but pretty damn close) and I can't get it to work. I just need to make a automatic test python script that can test different queries with different indexes and so on and for that I need to create and remove indexes a long the way. Hope someone has a solutions or maybe knows about some example codes out there I can download and study. Thanks Mestika

• "dynamic" keyword and JSON data

  - by Peter Perhác

  An action method in my ASP.NET MVC2 application returns a JsonResult object and in my unit test I would like to check that the returned JSON object indeed contains the expected values. I tried this: 1. dynamic json = ((JsonResult)myActionResult).Data; 2. Assert.AreEqual(JsonMessagesHelper.ErrorLevel.ERROR.ToString(), json.ErrorLevel); But I get a RuntimeBinderException "'object' does not contain a definition for 'ErrorLevel'". However, when I place a breakpoint on line 2 and inspect the json dynamic variable (see picture below), it obviously does contain the ErrorLevel string and it has the expected value, so if the runtime binder wasn't playing funny the test would pass. What am I not getting? What am I doing wrong and how can I fix this? How can I make the assertion pass?

• Finding N contiguous zero bits in an integer to the left of the MSB position of another integer

  - by James Morris

  The problem is: given an integer val1 find the position of the highest bit set (Most Significant Bit) then, given a second integer val2 find a contiguous region of unset bits, with the minimum number of zero bits given by width to the left of the position (ie, in the higher bits). Here is the C code for my solution: typedef unsigned int t; unsigned const t_bits = sizeof(t) * CHAR_BIT; _Bool test_fit_within_left_of_msb( unsigned width, t val1, t val2, unsigned* offset_result) { unsigned offbit = 0; unsigned msb = 0; t mask; t b; while(val1 >>= 1) ++msb; while(offbit + width < t_bits - msb) { mask = (((t)1 << width) - 1) << (t_bits - width - offbit); b = val2 & mask; if (!b) { *offset_result = offbit; return true; } if (offbit++) /* this conditional bothers me! */ b <<= offbit - 1; while(b <<= 1) offbit++; } return false; } Aside from faster ways of finding the MSB of the first integer, the commented test for a zero offbit seems a bit extraneous, but necessary to skip the highest bit of type t if it is set. I have also implemented similar algorithms but working to the right of the MSB of the first number, so they don't require this seemingly extra condition. How can I get rid of this extra condition, or even, are there far more optimal solutions? Edit: Some background not strictly required. The offset result is a count of bits from the high bit, not from the low bit as maybe expected. This will be part of a wider algorithm which scans a 2D array for a 2D area of zero bits. Here, for testing, the algorithm has been simplified. val1 represents the first integer which does not have all bits set found in a row of the 2D array. From this the 2D version would scan down which is what val2 represents. Here's some output showing success and failure: t_bits:32 t_high: 10000000000000000000000000000000 ( 2147483648 ) --------- ----------------------------------- *** fit within left of msb test *** ----------------------------------- val1: 00000000000000000000000010000000 ( 128 ) val2: 01000001000100000000100100001001 ( 1091569929 ) msb: 7 offbit:0 + width: 8 = 8 mask: 11111111000000000000000000000000 ( 4278190080 ) b: 01000001000000000000000000000000 ( 1090519040 ) offbit:8 + width: 8 = 16 mask: 00000000111111110000000000000000 ( 16711680 ) b: 00000000000100000000000000000000 ( 1048576 ) offbit:12 + width: 8 = 20 mask: 00000000000011111111000000000000 ( 1044480 ) b: 00000000000000000000000000000000 ( 0 ) offbit:12 iters:10 ***** found room for width:8 at offset: 12 ***** ----------------------------------- *** fit within left of msb test *** ----------------------------------- val1: 00000000000000000000000001000000 ( 64 ) val2: 00010000000000001000010001000001 ( 268469313 ) msb: 6 offbit:0 + width: 13 = 13 mask: 11111111111110000000000000000000 ( 4294443008 ) b: 00010000000000000000000000000000 ( 268435456 ) offbit:4 + width: 13 = 17 mask: 00001111111111111000000000000000 ( 268402688 ) b: 00000000000000001000000000000000 ( 32768 ) ***** mask: 00001111111111111000000000000000 ( 268402688 ) offbit:17 iters:15 ***** no room found for width:13 ***** (iters is the count of iterations of the inner while loop)
