  • Possible to have ampersands ("&") in URL BEFORE the query string?

    - by Mike Crittenden
    My client is determined to have a page at /nfm&t so I made a directory named nfm&t with an index.html (to test) and that URL is still throwing a 404. So apparently it's not that easy. Any ideas? Or is there a way to just redirect nfm&t to nfmt, so that the URL at least resolves? This is a Windows server, by the way, which throws a wrench into how I'm used to doing redirects.

  • What is the purpose of this string argument in a JavaScript function?

    - by Adel
    In the following function, there is the line: var username=getCookie("username"); Here's the whole function: function checkCookie() { var username=getCookie("username"); if (username!=null && username!="") { alert("Welcome again " + username); } else { username=prompt("Please enter your name:",""); if (username!=null && username!="") { setCookie("username",username,365); } } What is the point of the "username" argument being passed above? function getCookie(c_name) { var i,x,y,ARRcookies=document.cookie.split(";"); for (i=0;i<ARRcookies.length;i++) { x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("=")); y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1); x=x.replace(/^\s+|\s+$/g,""); if (x==c_name) { return unescape(y); } } } The whole code is here Thanks!

  • Windows Service Fails on Launch

    - by Jeff
    I'm trying to write a windows service. It installs fine, but fails when I run it with the following exception. I've searched for the string "MyNewProgramService", but I can't find any conversions that would throw this error. I've also added try/catch blocks to a bunch of code with custom exception handling without finding where this exception is occuring. I'm thinking it's somewhere in the auto-generated configuartion/setup code. Any ideas? Event Type: Error Event Source: MyNewProgram Event Category: None Event ID: 0 Date: 4/15/2010 Time: 12:48:34 PM User: N/A Computer: 20F7KF1 Description: Service cannot be started.

  • Berkeley DB tuple with unknown datatype

    - by Ronnie
    I'm working with a Berkeley database (in Java). I need to read a tuple where the sequence is a string, either an int or long, then another string. How can I determine if the tuple holds an int or a long? Depending on what the tuple holds, I'll do one of the following: String s1 = input.readString(); int num1 = input.readInt(); String s2= input.readString(); or String s1 = input.readString(); long num1 = input.readLong(); String s2= input.readString(); The int is 4 bytes and the long is 8 bytes. If the tuple holds an int and I read it in as a long, I get an invalid value as it converts the 4 byte int + 4 bytes of the following string into a long.

  • How to pass a reference to a string in JavaScript?

    - by ijjo
    Maybe a closure is my solution? Not exactly sure how to pull it off though. The code is set up like so: var globalVar = ''; var globalVar2 = ''; function func() { if (condition) func2(globalVar) else func2(globalVar2) } In func2() I cache some HTML in a main container into the appropriate global variable that I pass to it. Basically I have a main container that holds different pages depending on what tab they choose. For performance I want to cache the page into global vars so I need to know what tab is active to figure out which global var to assign the HTML to.

  • Pass a parameter from one jsp to another using form.action

    - by Ntz
    I have an ID that I need in the next jsp once the user click a button. I am trying to do the following: FirstJSP.jsp: function getSecond() { var frm = document.getElementById("frm"); frm.action = "**second.jsp?id=myId;"** frm.submit(); } ... form id="frm" ..... input type="button" value="Next" onclick="getSecond()"/ ...... This code takes me to my second page, but if I tried to access the id, it gives me an error since the id is null. I access the id in the second page by: final Long passedId = Long.parseLong(request.getParameter("id")); I think I am not passing the parameter correctly, but I don't know how to do it. Any ideas? Thank you so much!

  • Using Rails, how can I set my primary key to not be an integer-typed column?

    - by Rudd Zwolinski
    I'm using Rails migrations to manage a database schema, and I'm creating a simple table where I'd like to use a non-integer value as the primary key (in particular, a string). To abstract away from my problem, let's say there's a table employees where employees are identified by an alphanumeric string, e.g. "134SNW". I've tried creating the table in a migration like this: create_table :employees, {:primary_key => :emp_id} do |t| t.string :emp_id t.string :first_name t.string :last_name end What this gives me is what seems like it completely ignored the line t.string :emp_id and went ahead and made it an integer column. Is there some other way to have rails generate the PRIMARY_KEY constraint (I'm using PostgreSQL) for me, without having to write the SQL in an execute call? NOTE: I know it's not best to use string columns as primary keys, so please no answers just saying to add an integer primary key. I may add one anyway, but this question is still valid.

  • Set to null a parent record so that children are removed: howto?

    - by EugeneP
    How to delete a child row (on delete cascade ?) when setting a null value on a parent? Here's the db design. table A [id, b_id_1, b_id_2] table B [id, other fields...] b_id_1 and b_id_2 can be NULL if any of them is null, it means NO B records for corresponding FK (there are 2 of them) so (b_id_1,b_id_2) can be (null,null), (100, null), (null, 100_or_any_other_number) etc How in one SQL query both set b_id_1 or b_id_2 to null and delete all rows from B that have this id? What FK design should be applied to the 2 tables? what foreign keys should be added? A - B (FK_1: A.b_id_1 references B.id, FK_2: A.b_id_2 references B.id) and also B-A (FK_3: B.id references A.b_id_1, FK_4: B.id references A.b_id_2) ? But again, setting an A's b_id_1 or A's b_id_2 to null - will it remove any of B's records? I don't think so. So how to do that?

  • How can I fix this regex to allow a specific string?

    - by Sailing Judo
    This regex comes from Atwood and is used to filter out anchor tags with anything other than the href and a title: <a\shref="(\#\d+|(https?|ftp)://[-A-Za-z0-9+&@#/%?=~_|!:,.;]+)"(\stitle="[^"]+")?\s?> I need to allow am additional attribute that specifically matches: target="_blank". So the following url should be allowed: <a href="http://www.google.com" target="_blank"> I tried changing the pattern to these: <a\shref="(\#\d+|(https?|ftp)://[-A-Za-z0-9+&@#/%?=~_|!:,.;]+)"(\stitle="[^"]+")(\starget="_blank")?\s?> <a\shref="(\#\d+|(https?|ftp)://[-A-Za-z0-9+&@#/%?=~_|!:,.;]+)"(\stitle="[^"]+")(\starget=\"_blank\")?\s?> Clearly I don't know regex very well. How should the pattern be adjusted to allow the blank target and no other targets?

  • How can I do a left outer join where both tables have a where clause?

    - by cdeszaq
    Here's the scenario: I have 2 tables: CREATE TABLE dbo.API_User ( id int NOT NULL, name nvarchar(255) NOT NULL, authorization_key varchar(255) NOT NULL, is_active bit NOT NULL ) ON [PRIMARY] CREATE TABLE dbo.Single_Sign_On_User ( id int NOT NULL IDENTITY (1, 1), API_User_id int NOT NULL, external_id varchar(255) NOT NULL, user_id int NULL ) ON [PRIMARY] What I am trying to return is the following: is_active for a given authorization_key The Single_Sign_On_User.id that matches the external_id/API_User_id pair if it exists or NULL if there is no such pair When I try this query: SELECT Single_Sign_On_User.id, API_User.is_active FROM API_User LEFT OUTER JOIN Single_Sign_On_User ON Single_Sign_On_User.API_User_id = API_User.id WHERE Single_Sign_On_User.external_id = 'test_ext_id' AND API_User.authorization_key = 'test' where the "test" API_User record exists but the "test_ext_id" record does not, and with no other values in either table, I get no records returned. When I use: SELECT Single_Sign_On_User.id, API_User.is_active FROM API_User LEFT OUTER JOIN Single_Sign_On_User ON Single_Sign_On_User.API_User_id = API_User.id WHERE API_User.authorization_key = 'test' I get the results I expect (NULL, 1), but that query doesn't allow me to find the "test_ext_id" record if it exists but would give me all records associated with the "test" API_User record. How can I get the results I am after?

  • Calling a method on a Object says "disallows late binding"

    - by Maury Markowitz
    I have a calls called DtaDate that stores an integer "key", a string name, a string for the date, and a Date object that is created from that string. I have some code that needs to accept a date-like object. I'd like the user to be able to pass in anything date like - a Date object which I'll extract the information from, another DtaDate, a string with the date in it, or even the key, which I'll use to look up the DtaDate from a collection. So I have this: Friend Sub New(NameIn As String, DateFormulaIn As String, Optional FromDateIn As Object = Nothing) [stuff that works] [check that we got a FromDateIn...] If TypeOf FromDateIn Is DtaDate Then fdk = FromDateIn.Key Ans.FromDate = fdk VB tells me that "Option Strict On disallows late binding". The other cases, where a string or integer is the TypeOf, I use CInt or CStr. But this is the first time I've actually run into a case where the casting is a non-base type. What's the trick?
