• identify accounts using zend-openid [HELP]

  - by tawfekov

  Hi! , i had successfully implemented simple open ID authentication with the [gmail , yahoo , myopenid, aol and many others ] exactly as stackoverflow do but i had a problem with identifying accounts for example 'openid_ns' => string 'http://specs.openid.net/auth/2.0' (length=32) 'openid_mode' => string 'id_res' (length=6) 'openid_op_endpoint' => string 'https://www.google.com/accounts/o8/ud' (length=37) 'openid_response_nonce' => string '2010-05-02T06:35:40Z9YIASispxMvKpw' (length=34) 'openid_return_to' => string 'http://dev.local/download/index/gettingback' (length=43) 'openid_assoc_handle' => string 'AOQobUf_2jrRKQ4YZoqBvq5-O9sfkkng9UFxoE9SEBlgWqJv7Sq_FYgD7rEXiLLXhnjCghvf' (length=72) 'openid_signed' => string 'op_endpoint,claimed_id,identity,return_to,response_nonce,assoc_handle' (length=69) 'openid_sig' => string 'knieEHpvOc/Rxu1bkUdjeE9YbbFX3lqZDOQFxLFdau0=' (length=44) 'openid_identity' => string 'https://www.google.com/accounts/o8/id?id=AItOawk0NAa51T3xWy-oympGpxFj5CftFsmjZpY' (length=80) 'openid_claimed_id' => string 'https://www.google.com/accounts/o8/id?id=AItOawk0NAa51T3xWy-oympGpxFj5CftFsmjZpY' (length=80) i thought that openid_claimed_id or openid_identity is identical for every account but after some testing turns out the claimed id is changeable by the users them self in yahoo and randomly changing in case of gmail FYI am using zend openid with a bit modification on consumer class and i can't use SERG [Simple Refistration Extension] cuz currently it uses openid v1 specification :( i hadn't read the specification of openid so if any body know please help me to how to identify openid accounts to know if this account has signed in before or not

• Is Assert.Fail() considered bad practice?

  - by Mendelt

  I use Assert.Fail a lot when doing TDD. I'm usually working on one test at a time but when I get ideas for things I want to implement later I quickly write an empty test where the name of the test method indicates what I want to implement as sort of a todo-list. To make sure I don't forget I put an Assert.Fail() in the body. When trying out xUnit.Net I found they hadn't implemented Assert.Fail. Of course you can always Assert.IsTrue(false) but this doesn't communicate my intention as well. I got the impression Assert.Fail wasn't implemented on purpose. Is this considered bad practice? If so why? @Martin Meredith That's not exactly what I do. I do write a test first and then implement code to make it work. Usually I think of several tests at once. Or I think about a test to write when I'm working on something else. That's when I write an empty failing test to remember. By the time I get to writing the test I neatly work test-first. @Jimmeh That looks like a good idea. Ignored tests don't fail but they still show up in a separate list. Have to try that out. @Matt Howells Great Idea. NotImplementedException communicates intention better than assert.Fail() in this case @Mitch Wheat That's what I was looking for. It seems it was left out to prevent it being abused in another way I abuse it.

• Javascript array length incorrect on array of objects

  - by Serenti

  Could someone explain this (strange) behavior? Why is the length in the first example 3 and not 2, and most importantly, why is the length in the second example 0? As long as the keys are numerical, length works. When they are not, length is 0. How can I get the correct length from the second example? Thank you. a = []; a["1"] = {"string1":"string","string2":"string"}; a["2"] = {"string1":"string","string2":"string"}; alert(a.length); // returns 3 b = []; b["key1"] = {"string1":"string","string2":"string"}; b["key2"] = {"string1":"string","string2":"string"}; alert(b.length); // returns 0

• Error_No_Token by adding printer driver (c#)

  - by user1686388

  I'm trying to add printer drivers using the windows API function AddPrinterDriver. The Win32 error 1008 (An attempt was made to reference a token that does not exist.) was always generated. My code is shown as following [DllImport("Winspool.drv")] static extern bool AddPrinterDriver(string Name, Int32 Level, [in] ref DRIVER_INFO_3 DriverInfo); [StructLayout(LayoutKind.Sequential)] public struct DRIVER_INFO_3 { public Int32 cVersion; public string Name; public string Environment; public string DriverPath; public string DataFile; public string ConfigFile; public string HelpFile; public string DependentFiles; public string MonitorName; public string DefaultDataType; } //....................... DRIVER_INFO_3 di = new DRIVER_INFO_3(); //...................... AddPrinterDriver(Environment.MachineName, 3, ref di); I have also tried to get a token by "ImpersonateSelf" before adding the printer driver. But the error 1008 insists. Does anyone have an idea? best regards.

• How efficient is an if statement compared to a test that doesn't use an if? (C++)

  - by Keand64

  I need a program to get the smaller of two numbers, and I'm wondering if using a standard "if x is less than y" int a, b, low; if (a < b) low = a; else low = a; is more or less efficient than this: int a, b, low; low = b + ((a - b) & ((a - b) >> 31)); (or the variation of putting int delta = a - b at the top and rerplacing instances of a - b with that). I'm just wondering which one of these would be more efficient (or if the difference is to miniscule to be relevant), and the efficiency of if-else statements versus alternatives in general.

• How to compare a string column(as DateTime) in LINQ?

  - by lyon

  I have a database with a ValidDate field - it's a string(we made a mistake, it should be a datetime, but we can't modify the database now.) and now I want to compare this filed with a parameter(validDateStart) from the website: priceList = priceList.Where(p => Convert.ToDateTime(p.ValidDate) >= Convert.ToDateTime(validDateStart)); var list = initPriceList.ToList(); But I get an error: The method ToDateTime is not implemented. Can anybody give me some help? Thanks!

• How do I access Dictionary items?

  - by salvationishere

  I am developing a C# VS2008 / SQL Server website app and am new to the Dictionary class. Can you please advise on best method of accomplishing this? Here is a code snippet: SqlConnection conn2 = new SqlConnection(connString); SqlCommand cmd = conn2.CreateCommand(); cmd.CommandText = "dbo.AppendDataCT"; cmd.CommandType = CommandType.StoredProcedure; cmd.Connection = conn2; SqlParameter p1, p2, p3; foreach (string s in dt.Rows[1].ItemArray) { DataRow dr = dt.Rows[1]; // second row p1 = cmd.Parameters.AddWithValue((string)dic[0], (string)dr[0]); p1.SqlDbType = SqlDbType.VarChar; p2 = cmd.Parameters.AddWithValue((string)dic[1], (string)dr[1]); p2.SqlDbType = SqlDbType.VarChar; p3 = cmd.Parameters.AddWithValue((string)dic[2], (string)dr[2]); p3.SqlDbType = SqlDbType.VarChar; } but this is giving me compiler error: The best overloaded method match for 'System.Collections.Generic.Dictionary<string,string>.this[string]' has some invalid arguments I just want to access each value from "dic" and load into these SQL parameters. How do I do this? Do I have to enter the key? The keys are named "col1", "col2", etc., so not the most user-friendly. Any other tips? Thanks!

• php strpos special characters

  - by Radu

  I'm using PHP Version 5.1.6 I have a string (session file) and need to extract a value from it, so i'm searching for a needle in the string but it returns false, I reduced the code to this: $string = ';SERVER_NAME|s:17:"stackoverflow.com";REMOTE_ADDR|s:13:"69.59.196.211";'; $start = strpos($string, ';SERVER_NAME|s:"'); echo $start; // prints nothing because $start = false $start = strpos($string, 'SERVER_NAME|s:'); echo $start; // prints 1; As you noticed if I have the character ';' or the character '"' in the needle, the search returns false, I tryed to use chr() for all characters in the needle but had the same result, If I remove the ';' and the '"' from the string if finds the needle in the string. How can I search special characters in a string using PHP ?

• How do I render a partial to a string from within a filter attached to a controller

  - by Tristan Havelick

  I have some code I need to use in multiple controllers in a rails 1.0 application (I can't, for strange reasons upgrade to a newer rails). I've extracted the relevant code into a filer object, and I'm using the around_filter construct to execute it. Before the extract, I was using the method render_to_string() to get the contents of a rendered partial into a string. However, this method is protected, so I am unable to access it from within my Filter object. As a workaround, I tried adding this to my ApplicationController: def render_to_string(*a) super(*a) end this seems to have remedied the protection level issue, but now I get the error: Can only render or redirect once per action When no such error occurred before the extraction. Why? Is there a different approach I should take here?

• Creating a Type object corresponding to a generic type

  - by Alexey Romanov

  In Java, how can I construct a Type object for Map<String, String>? System.out.println(Map<String, String>.class); doesn't compile. One workaround I can think of is private Map<String, String> dummy() { throw new Error(); } Type mapStringString = Class.forName("ThisClass").getMethod("dummy", null).getGenericReturnType(); Is this the correct way?

• LINQ Equivalent query

In other words, I am trying to get the LINQ equivalent of select value from [courses] where [courses].key in ( select [courses].key from courses,students where [students].id LIKE '%courses.key%' ) How should the LINQ query be framed?

• How can I test whether a csv file is currently open and being written to - the file, not a file hand

  - by Henry

  I've seen a few questions/answers here that deal with this, but none really give me an answer/solution. I've got a Clipper system writing csv files to a Windows directory. I have a perl script running on a Linux server that is reading a mount of that Windows directory and importing the files to a database. Right now we're using flag files to indicate when a csv is no longer being written to; the flag files gets written after the csv is done. I'd really rather just get what I need from the csv itself, but I can't seem to find a way to tell when the file is open and being written to. lsof doesn't seem to answer my need. I've tried using flock and open the file with an exclusive lock, thinking it might throw an error if the file is being modified, but it doesn't. Any thoughts?

• Any utility to test expand C/C++ #define macros?

  - by Randy

  It seems I often spend way too much time trying to get a #define macro to do exactly what i want. I'll post my current delemia below and any help is appreciated. But really the bigger question is whether there is any utility someone could reccomend, to quickly display what a macro is actually doing? It seems like even the slow trial and error process would go much faster if I could see what is wrong. Currently, I'm dynamically loading a long list of functions from a DLL I made. The way I've set things up, the function pointers have the same nanes as the exported functions, and the typedef(s) used to prototyp them have the same names, but with a prepended underscor. So I want to use a define to simplfy assignments of a long long list of function pointers. For example, In the code statement below, 'hexdump' is the name of a typdef'd function point, and is also the name of the function, while _hexdump is the name of the typedef. If GetProcAddress() fails, a failure counter in incremented. if (!(hexdump = (_hexdump)GetProcAddress(h, "hexdump"))) --iFail; So lets say I'd like to rplace each line like the above with a macro, like this... GETADDR_FOR(hexdump ) Well this is the best I've come up with so far. It doesn't work (my // comment is just to prevent text formatting in the message)... // #define GETADDR_FOR(a) if (!(a = (#_#a)GetProcAddress(h, "/""#a"/""))) --iFail; And again, while I'd APPRECIATE an insight into what silly mistake I've made, it would make my day to have a utility that would show me the error of my ways, by simply plugging in my macro

• How to test a .net application against a proxy?

  - by Pierre-Alain Vigeant

  I need to support the use of proxy on our application that is using WCF connections. We do not have any proxy server on our network and I don't want to disrupt our corporate network by requesting a proxy installation. I was thinking of installing a proxy server on a local virtual machine and configurating Internet Explorer so that it will challenge that proxy. I don't know what proxy software to use (I don't want to install ISA server) and I don't know how to configure one. Does someone have any suggestion for a easy to use software that will require an authentication for any WCF services and do you have any guideline that would be helpful to know when testing a software against a proxy?

• JSF, writeAttribute("value", str, null) fails with strings obtained through ValueExpression.getValue

  - by Roma

  Hello, I'm having a somewhat weird problem with custom JSF component. Here's my renderer code: public class Test extends Renderer { public void encodeBegin(final FacesContext context, final UIComponent component) throws IOException { ResponseWriter writer = context.getResponseWriter(); writer.startElement("textarea", component); String clientId = component.getClientId(context); if (clientId != null) writer.writeAttribute("name", clientId, null); ValueExpression exp = component.getValueExpression("value"); if (exp != null && exp.getValue(context.getELContext()) != null) { String val = (String) exp.getValue(context.getELContext()); System.out.println("Value: " + val); writer.writeAttribute("value", val, null); } writer.endElement("textarea"); writer.flush(); } } The code generates: <textarea name="j_id2:j_id12:j_id19" value=""></textarea> Property binding contains "test" and as it should be, "Value: test" is successfully printed to console. Now, if I change the code to: public void encodeBegin(final FacesContext context, final UIComponent component) throws IOException { ResponseWriter writer = context.getResponseWriter(); writer.startElement("textarea", component); String clientId = component.getClientId(context); if (clientId != null) writer.writeAttribute("name", clientId, null); ValueExpression exp = component.getValueExpression("value"); if (exp != null && exp.getValue(context.getELContext()) != null) { String val = (String) exp.getValue(context.getELContext()); String str = "new string"; System.out.println("Value1: " + val + ", Value2: " + str); writer.writeAttribute("value", str, null); } writer.endElement("textarea"); writer.flush(); } generated html is: <textarea name="j_id2:j_id12:j_id19" value="new string"></textarea> and console output is "Value1: test, Value2: new string" What's going on here? This doesn't make sense. Why would writeAttribute differentiate between the two strings? Additional info: The component extends UIComponentBase I am using it with facelets

• Using Array Variables For FILE_GET_CONTENTS

  - by Whoshooter

  I have a script all done now and everything has been debugged and it works, except for the last hurdle. This script grabs pertinent information on bank web sites, takes that data and uses it to populate a template and then it's all posted to Wordpress - BUT I get an error because the file_get_contents function fails taking each url from the Array. I've var_dumped the array and all the URLS are there in the [0] key, so this is what I tried. master data is the scraped URL source the script uses urlscrape_array is the collection of URLS $master_data = file_get_contents($urlscrape_array[0]); When I run the script using a URL like below it works beautifully every time; $master_data = file_get_contents("http://www.somesite/somepage.html"); This is the error I get when I try to use the first example' Warning: file_get_contents() expects parameter 1 to be string, array given in /home3/path/public_html/mysite.com/boise_project/scriptmainpage.php on line 13 As requested here is a sample of the var_dump on $urlscrape_array[0] array(504) { [0]=> string(56) "http://www.somepage.com/somepage-3178.html" [1]=> string(54) "http://www.somepage.com/somepage-16.html" [2]=> string(56) "http://www.somepage.com/somepage-3202.html" [3]=> string(56) "http://www.somepage.com/somepage-4324.html" [4]=> string(56) "http://www.somepage.com/somepage-4777.html" [5]=> string(56) "http://www.somepage.com/somepage-5140.html" [6]=> string(56) "http://www.somepage.com/somepage-5220.html" [7]=> string(56) "http://www.somepage.com/somepage-9205.html" [8]=> string(56) "http://www.somepage.com/somepage-3251.html" [9]=> string(56) "http://www.somepage.com/somepage-3323.html" [10]=> string(56) "http://www.somepage.com/some-page-3797.html" [11]=> string(56) "http://www.somepage.com/some-page-4145.html" [12]=> string(56) "http://www.somepage.com/some-page-3191.html" [13]=> string(55) "http://www.somepage.com/some-page-329.html" [14]=> string(56) etc....
