• Private JQuery instance

  - by Nir Levy

  We are writing a SaaS like solution that requires our customers to SCRIPT SRC some javascript code we are building (think Google Analytics scenario). We would like to use JQuery. However, since our customers might already have conflicting JQuery versions or other conflicting frameworks (prototype.js for one) we cannot tell them to source jquery.js. We were thinking of coping the jquery source as to create a 'private' jquery instance and simple search/replace the JQuery and $ functions with myJQuery and $J Is there any reason for this not to work? has anyone tried something like this? What can we do about plugins?

• CTE and last known date processing

  - by stackoverflowuser

  Input @StartDate = '01/25/2010' @EndDate = '02/06/2010' I have 2 CTEs in a stored procedure as follows: with CTE_A as ( [gives output A..Shown below] ), with CTE_B as ( Here, I want to check if @StartDate is NOT in output A then replace it with the last known date. In this case, since @startdate is less than any date in output A hence @StartDate will become 02/01/2010. Also to check if @EndDate is NOT in output A then replace it with the last known date. In this case, since @enddate is 02/06/2010 hence it will be replace with 02/05/2010. // Here there is a query using @startDate and @EndDate. ) output A Name Date A 02/01/2010 B 02/01/2010 C 02/05/2010 D 02/10/2010

• Algorithm for Source Control System?

  - by Michael Stum

  I need to write a simple source control system and wonder what algorithm I would use for file differences? I don't want to look into existing source code due to license concerns. I need to have it licensed under MPL so I can't look at any of the existing systems like CVS or Mercurial as they are all GPL licensed. Just to give some background, I just need some really simple functions - binary files in a folder. no subfolders and every file behaves like it's own repository. No Metadata except for some permissions. Overall really simple stuff, my single concern really is how to store only the differences of a file from revision to revision without wasting too much space but also without being too inefficient (Maybe store a full version every X changes, a bit like Keyframes in Videos?)

• Convert ASP.NET membership system to secure password storage

  - by wrburgess

  I have a potential client that set up their website and membership system in ASP.NET 3.5. When their developer set up the system, it seems he turned off the security/hashing aspect of password storage and everything is stored in the clear. Is there a process to reinstall/change the secure password storage of ASP.NET membership without changing all of the passwords in the database? The client is worried that they'll lose their customers if they all have to go through a massive password change. I've always installed with security on by default, thus I don't know the effect of a switchover. Is there a way to convert the entire system to a secure password system without major effects on the users?

• iphone: accessing the preferences localization file from code

  - by phonecoddy

  I was just facing the following problem and couldn't find a solution for it. Hopefully someone could help. The app I am working on has some preferences, which are using a localization file. Now I want to use labels in my app, which display the exact names, which are used in the localization file for the preferences. But I couldn't find a way to access the information which is stored in Settings.bundle - en.lproj - localizationfile.strings. to make this clear: If you open your preferences for your app, the display shows the localized string of the title and the value of the setting. I need to access the localized string of the title of each preference from my code. Does any know how to do this?

• In C, how do you capture a group with regex?

  - by Sylvain

  Hi, I'm trying to extract a string from another using regex. I'm using the POSIX regex functions (regcomp, regexec ...), and I fail at capturing a group ... For instance, let the pattern be something as simple as "MAIL FROM:<(.*)>" (with REG_EXTENDED cflags) I want to capture everything between '<' and '' My problem is that regmatch_t gives me the boundaries of the whole pattern (MAIL FROM:<...) instead of just what's between the parenthesis ... What am I missing ? Thanks in advance,

• How do I combine an unmanaged dll and a managed assembly into one file?

  - by Lasse V. Karlsen

  SQLite from PHX Software has combined a managed assembly (System.Data.SQLite) with an unmanaged dll (the SQLite 32- or 64-bit dll) into one file, and managed to link them together. How do I do this? Do I need to embed the managed assembly into the unmanaged dll, or vice versa? ie. my questions are: In which order do I need to do this? What tools or knowledge do I need in order to do this? How (if different) do I link to the exported functions from the unmanaged dll in my managed code? The reason I ask this is that I want to build a managed zLib wrapper. I know there is managed classes in .NET but from experience they're a bit limited (and a bit boneheaded in that they don't do proper buffering), so I'd like to create my own copy, also because I want to learn how to do this. So does anyone know what I need to do and how?

• Dollar ($) sign in password string treated as variable

  - by ncatnow

  Spent some time troubleshooting a problem whereby a PHP/MySQL web application was having problems connecting to the database. The database could be accessed from the shell and phpMyAdmin with the exact same credentials and it didn't make sense. Turns out the password had a $ sign in it: $_DB["password"] = "mypas$word"; The password being sent was "mypas" which is obviously wrong. What's the best way to handle this problem? I escaped the $ with a \ $_DB["password"] = "mypas\$word"; and it worked. I generally use $string = 'test' for strings which is probably how I avoided running into this before. Is this correct behavious? What if this password was stored in a database and PHP pulled it out - would this same problem occur? What am I missing here...

• Pageview implementation

  - by The Elite Gentleman

  Hi everyone I want to add a pageview feature on my current web application. This page view is based on the count of user viewing the page. It must be unique, i.e. I must not view a person's page 10000 times and record it as 10000 views, just record 1 view instead. My question is, should I base my pageview count on IP address? If not, what is/are the best approach in doing this? I know that if the person has logged in to my system, I can simply use the user id stored in the session and check on the record if the user has/hasn't viewed the page and update accordingly. But for "anonymous" viewers, what is the best approach? Thanks. PS How does Youtube does it?

• ruby c extensions: character values over 127

  - by Adrian

  I am trying to make a C extension for Ruby that includes a method returning a string, which will sometimes have character values that need to be in an unsigned char. In http://github.com/shyouhei/ruby/blob/trunk/README.EXT, all of the functions listed for turning C strings into Ruby strings take signed chars. So I couldn't do this: unsigned char bytes[] = {0xf0, 0xf1, 0xf2}; return rb_str_new(bytes, 3); How could I make a method that returns these types of strings? In other words, how would I make a C extension with a method returning "\xff"?

• Decimal data Type Display scale part as zero

  - by Wael Dalloul

  I have Decimal field in SQLserver 2005 table, Price decimal(18, 4) if I write 12 it will be converted to 12.0000, if I write 12.33 it will be converted into 12.3300. Always it's putting zero to the right of the decimal point in the count of Scale Part(4). I was using these in SQL Server 2000, it was not behaving like this, in SQL Server 2000 if I put 12.5 it will be stored as 12.5 not as 12.5000 what SQLServer2005 do. My Question is how to stop SQL Server 2005 from putting zeros to the right of the decimal point?

• (php) how to properly 'save' info in forms completed thus far

  - by hatorade

  So i have a form that on paper is 40 pages long. I was going to take the natural sections of this form, and make separate html forms for each section, with the idea that on the first page there would be a first form, then you hit 'Continue to next section' which essentially is the 'submit' button, which moves the user to section two, etc, until they hit the last section. i am not actually storing the results of the form in a database, but rather sending an email. the idea then is to store the separate form answers (one html form per section in the real form) as arrays or objects in the session, so that if they go back to a section in the form, it repopulates the values they entered since they are stored in the session. the result would be an array in the session storing the results for each of my forms, and i have one form for each section. my question is: is it secure to temporarily store things like SSNs or driver's license numbers as session variables? why or why not?

• JQuery Scrollable List Dissapears if scrolled IE7

  - by namtax

  Hi there I have created a time picker using jquery, using the following code // Display Time Picker $('.time').click(function(){ $('.timePicker').remove(); var thisTime = $(this); var timePicker = '<ul class="timePicker">' timePicker += '<li>09:00</li>' timePicker += '<li>09:15</li>' timePicker += '</ul>' thisTime.after(timePicker); $('.timePicker').fadeIn() $('.timePicker li').click(function(){ term = $(this).html(); $(thisTime).val(term); $('.timePicker').remove(); }); }).blur(function(){ $('.timePicker').fadeOut(); }); This adds a dropdown scrollable list of times to any input field with the class "time". This functions as expected in all browsers apart from IE7, where if I scroll the list to choose a time lower down in the list, the list dissapears.. Hope that makes sense, any help would be much appreciated Many thanks

• whats faster, more efficient, loading a js file with arrays or populating arrays from tables

  - by Leigh

  I am rebuilding an ecom site where the product data is stored in a multidimensional JS array that gets loaded on page load. This data is constantly being accessed with JS due to the nature of the site, to update prices based on user selections. There are many options that affect final price. From a programming standpoint, a DB table is much easier to maintain and update than are JS arrays, and since I am porting the site over to PHP and MYSQL, I have been considering moving these arrays into tables. So, would it be better to populate an array from the DB on load so that the pricing data is always available to the JS, or stay with hard coded JS files? I considered getting data via ajax as needed, but since this site has to constantly update pricing with user interaction, I have pretty much ruled that out. How would you handle it?

• ASP.NET (VB) - Close an opened SQL connection inside Function

  - by B1GB0Y

  Can anyone tell me how I close an opened SQL connection inside a Function? I call a Select Function like this: Function Selec(ByVal SQLStr As String) As SqlDataReader Dim SQLConn As New SqlConnection() Dim SQLCmd As New SqlCommand() SQLConn.ConnectionString = Session("bd") SQLConn.Open() SQLCmd.Connection = SQLConn SQLCmd.CommandText = SQLStr Selec = SQLCmd.ExecuteReader End Function And in another page I do a While method to retrieve me the data like this: (Note: BDcon.BD is the name of the Class that have Functions) Dim write as New BDcon.BD Dim menu As SqlDataReader = writeBD.Selec("SELECT something from Table") While menu.Read 'Do something End While menu.Close 'This close just the DataReader and not the SqlConnection Finally I want to Close my SQL Connection by Function like this: Function Close() As SqlConnection Dim SQLConn As New SqlConnection() SQLConn.ConnectionString = Session("bd") SQLConn.Close() End Function I think that the problem is on the Close() Function, I want to close the connection but I don't know how to call my Opened Conneciton. Please anyone can help me? Thanks in advance :)

• How to retrieve email from GMail account using PHP?

  - by Tatu Ulmanen

  Hi, I'm trying to automatically retrieve some email from my GMail account for further parsing, but I can't get my head around on how to do that. I've searched the internets and it suggested that I use PHP's imap functions, like this: $server = '{imap.gmail.com:993/ssl}'; $connection = imap_open($server, '[email protected]', 'password'); But using that code, I get: Warning: imap_open() [function.imap-open]: Couldn't open stream {imap.gmail.com:993/ssl} Any idea what I am doing wrong? Any server setting that might be preventing me from making a connection to GMail (I'm using a shared service)? Is the address even right? Has anyone ever managed to do something like this? I've found tons of examples on how to send email via GMail, but very little of retrieving. Any help is much appreciated.

• Interpolating 1D Gaussian into 2D Gaussian

  Let's say I have a 1D Gaussian function. Its length is 600 for that matter. I want to Interpolate it into 2D Gaussian of the size 600 X 600. This is the code I wrote (OTFx is the Gaussian Function, OTF - 2d Interpolated Function): [x, y] = meshgrid([-300:299], [-300:299]); r = sqrt((x .^ 2) + (y .^ 2)); OTF = interp1([-300:299], OTFx, r(:), 'spline'); OTF = reshape(OTF, [600, 600]); The problem is I get Overshoot at the end: How can I prevent it? Is there better Interpolating algorithm for Monotonic Descending Functions?

• How can I prevent SerializeJSON from changing Yes/No/True/False strings to boolean?

  - by Dan Roberts

  I have a data struct being stored in JSON format, converted using the serializeJSON function. The problem I am running into is that strings that can be boolean in CF such as Yes,No,True,and False are converted into JSON as boolean values. Below is example code. Any ideas on how to prevent this? Code: <cfset test = {str='Yes'}> <cfset json = serializeJSON(test)> <cfset fromJSON = deserializeJSON(json)> <cfoutput> #test.str#<br> #json#<br> #fromJSON.str# </cfoutput> Result: Yes {"STR":true} YES

• Upsert - Efficient Update or Insert in VB.Net, SQL Server

  - by HK1

  I'm trying to understand how to streamline the process of inserting a record if none exists or updating a record if it already exists. I'm not using stored procedures, although maybe that would be the most efficient way of doing this. The actual scenario in which this is necessary is saving a user preference/setting to my SettingsUser table. In MS Access I would typically pull a DAO recordset looking for the specified setting. If the recordset comes back empty then I know I need to add a new record which I can do with the same recordset object. On the other hand, if it isn't empty, I can just update the setting's value right away. In theory, this is only two database operations. What is the recommended way of doing this in .NET?

• What is the safest way for a PHP script to connect to a local PostgreSQL instance on Linux?

  - by Botond Balázs

  I think if I granted the apache user appropriate privileges and used the ident authentication method, that would make the connection more secure because then the password wouldn't need to be stored in a connection string. Also, that way the security of the connection would depend on how secure the host system is. I disabled root login over ssh and only permit public key authentication so I think it is pretty secure. Does this have any significant security benefits or is it just wishful thinking? Is it necessary at all?

• Is there a way to only backup a SQL 2005 database structure fully, but only the data in a certain se

  - by TheSoftwareJedi

  I have several schemas in my database, and the largest one ("large" meaning disk space consumed) is my "web" schema which is a denormalized copy of data in the operational schemas. This denormalized data is able to be reconstructed at anytime, and is merely there for extremely fast read purposes. Since the data is redundant, and VERY large - I'd like to exclude it from being backed up. I already have stored procedures that can regenerate all of the data in that schema in a couple of hours - for use in the event of a failure. I assume I can split the tables in this schema out to another data file or such (ideally even on another drive for faster reads), but is there a way to never have that data file backup, yet still in the event of a failure its structure could be restored (and other DDL stuff like procs, views, etc)? Somewhat related, can I also have these tables not do transaction logging, if I go to "Full" backup mode for the rest of the database?
