• How to read back and print text with newlines from a Python (Django) string with HTML?

  - by user1801486

  If someone types in a phrase, such as: I see you driving round town with the girl I love, and I’m like: haiku. (no blank lines between each line, but the text is written on three separate lines) into a text box on a web page, and then presses a button which is then stored in a database via Django, and that string is read back and printed on a page, how can I get it to print on an HTML page with the newlines still in the text? So instead of it being printed back as: I see you driving round town with the girl I love, and I’m like: haiku. It would print as: I see you driving round town with the girl I love, and I’m like: haiku. I know that if I use: (textarea)soAndSo.body(/textarea), this preserves the newlines that were in the file when the user typed it up originally. How can I get this same effect, but without having to use textarea boxes?

• Pop up password protect

  - by steve

  Please not that I fully understand this is a dumb ass idea, but its not my idea. We need to deter people visiting a certain page on our site. It's written in ASP and I don'tknow ASP! Can anyone tell me how I can have a pop up box load when the URL is visited where by people have to enter a username / password. The user name / password should be stored in the javascript. (Yes I know) The only real requirement is that this happen anytime the page is loaded and it stays on that page. So the page is test.asp - javascript pops up they enter credentials and if right remain on test.asp Thanks

• WebService Security

  - by LauzPT

  Hello, I'm developing an project, which consists in a webservice and a client application. It's a fair simple scenario. The webservice is connected to a database server, and the client consumes from the webserver in order to get information retrieved from the database. The thing is: 1. The client application can only display data after a previous authentication; 2. All the data transferred between Web Service and clients must be confidential; 3. Data integrity shouldn’t be compromised; I'm wondering what is the best way to achieve these requirements. The first thing I thought about, was sending the server a digital signature containing a client certificate, to be stored in the server, and used as comparison for authentication. But I investigated a little about webservice security, and I'm no longer certain that this is the best option. Can anyone give me an opinion about this? TIA

• Getting list of fields back from 'use fields' pragma?

  - by makenai

  So I'm familiar with the use fields pragma in Perl that can be used to restrict the fields that are stored in a class: package Fruit; use fields qw( color shape taste ); sub new { my ( $class, $params ) = @_; my $self = fields::new( $class ) unless ref $class; foreach my $name ( keys %$params ) { $self->{ $name } = $params->{ $name }; } return $self; } My question is.. once I've declared the fields at the top, how I can get the list back.. say because I want to generate accessors dynamically? Is keys %FIELDS the only way? Secondarily, is there a more efficient way to pre-populate the fields in the constructor than looping through and assigning each parameter as I am above? Thanks!

• Using Linq on a Dataset

  - by JasonMHirst

  Can someone enlighthen me with regards to Linq please? I have a dataset that is populated via a SQL Stored Procedure, the format of which is below: Country | Brand | Variant | 2004 | 2005 | 2006 | 2007 | 2008 The number of rows varies between 50 and several thousand. What I'm trying to do is use Linq to interrogate the dataset (there will be several Linq queries based on user options), but a simple example would be to SUM the year columns based on Brand. I have the following that I believe creates a template for me to work with: But from here on I'm absolutely stuck! sqlDA.Fill(ds, "Profiler") Dim brandsQuery = From cust In ds.Tables(0).AsEnumerable() Select _BrandName = cust.Item("BrandName"), _y0 = cust.Item("1999"), _y1 = cust.Item("2004"), _y2 = cust.Item("2005"), _y3 = cust.Item("2006"), _y4 = cust.Item("2007"), _y5 = cust.Item("2008") I'm tried to look at examples, but can't see any that are VB.Net based and/or show me how to Sum/Group. Can someone please provide an example so I can perhaps learn from it. Thanks.

• Inheriting database connection in PHP OOP

  - by vrode

  My abstract class Database is made for database interaction and any child of this class (UserDatabase, ActionDatabase, EventDatabase) inherits its database connection which is defined as static. `abstract class Database { static $connection = mysql_connect( ); } class UserDatabase extends Database { ... public function __construct( ) { $connection ? "connected" : "not connected"; $this-table = "users"; mysql_query( "FROM " . $this-table . " SELECT *" ); } } ` Does that mean, that my database connection is only set up and stored in memory once and passed on to subclasses as reference without being replicated for each instance? Is this how you would implement you OOP-correct database interface?

• Would you store binary data in database or in file system?

  - by paul

  This is a question which has been asked before (large-text-and-images-in-sql) but mainly for data which will be changed. In my case the data will be stored and never changed. Just seems sensible to keep everything together. Are there any reasons why I should not store static binary data in a database? Assuming it is a sensible thing to do, are there any advantages to storing such data in separate tables? (You might begin to realise now that I'm not a DB expert...) Clarify: There will probably be no more than 10-20 users but these will be in the US and in the UK. The binary data will have to be transfered in any case.

• Database suggestion

  - by superartsy

  I am working on an enterprise level product that is designed around SQL Express Database ( views,concurrent users,stored procedures,case,IF).Though we dont use any SQL Server advanced features, if the database size of 4Gb in express ends up being a limitation customers can move to advanced versions of SQL Server. However my problem is, SQL Express deployment is not easy and the installer size is huge. This is a major drawback for someone looking to try our product.You dont want end users to not buy a product becos the download is huge. Does anyone have any recommendations of a database that has a smaller footprint but all the features of Express and which can be migrated to express?

• functions in assembler

  - by stupid_idiot

  hi, i have philosophised about the purpose of stack a little bit and after some coding i figured out what is it's strength. The only thing that lies in my stomache is how does it work with functions? I tried to make some easy function for adding two numbers using universal registers but I suppose that's not how does it work in C for example.. where are all the parameters, local variables and where is the result stored? how would you rewrite this to assembler?(how would compiler for C rewrite it?) int function(int a, int &b, int *c){ return a*(b++)+(*c); } i know this example kinda sucks.. but this way i can understand all the possibilities

• Reusing a vector in C++

  - by Bobby

  I have a vector declared as a global variable that I need to be able to reuse. For example, I am reading multiple files of data, parsing the data to create objects that are then stored in a vector. vector<Object> objVector(100); void main() { while(THERE_ARE_MORE_FILES_TO_READ) { // Pseudocode ReadFile(); ParseFileIntoVector(); ProcessObjectsInVector(); /* Here I want to 'reset' the vector to 100 empty objects again */ } } Can I reset the vector to be "vector objVector(100)" since it was initially allocated on the stack? If I do "objVector.clear()", it removes all 100 objects and I would have a vector with a size of 0. I need it to be a size of 100 at the start of every loop.

• string manipulations in C

  - by Vivek27

  Following are some basic questions that I have with respect to strings in C. If string literals are stored in read-only data segment and cannot be changed after initialisation, then what is the difference between the following two initialisations. char *string = "Hello world"; const char *string = "Hello world"; When we dynamically allocate memory for strings, I see the following allocation is capable enough to hold a string of arbitary length.Though this allocation work, I undersand/beleive that it is always good practice to allocate the actual size of actual string rather than the size of data type.Please guide on proper usage of dynamic allocation for strings. char *string = (char *)malloc(sizeof(char));

• OpenGL index buffer object with additional data

  - by muksie

  I have a large set of lines, which I render from a vertex buffer object using glMultiDrawArrays(GL_LINE_STRIP, ...); This works perfectly well. Now I have lots of vertex pairs which I also have to visualize. Every pair consists of two vertices on two different lines, and the distance between the vertices is small. However, I like to have the ability to draw a line between all vertex pairs with a distance less than a certain value. What I like to have is something like a buffer object with the following structure: i1, j1, r1, i2, j2, r2, i3, j3, r3, ... where the i's and j's are indices pointing to vertices and the r's are the distances between those vertices. Thus every vertex pair is stored as a (i, j, r) tuple. Then I like to have a (vertex) shader which only draws the vertex pairs with r < SOME_VALUE as a line. So my question is, what is the best way to achieve this?

• Approach to data wrapping

  - by Mikhail

  I'm developing in PHP and MySQL. The information about the currently logged in user is stored in many different tables. The information that I need on each page, I preload. However if something is needed from a rarely accessed table - then I do $newdata = $db->Query('SELECT * FROM rare_table WHERE user_id='.$user->id); I would like to simplify the above to a point where I don't have to specify that the query should be limited to this particular user. An ideal function call would be: $newdata = $user->Query('SELECT * FROM rare_table'); Obviously I'd have to parse the SQL and add a WHERE clause. Or add to the already existing clause. Questions: are there tools to do this? How can I develop this? Is this even a good idea?

• OpenId with Desktop Application ?

  - by user284523

  We're using an API from a provider; in their next version, they would provide an OpenId server but mostly the users are using their desktop application. An other website we're building would be opened from this application and we supposedly would connect with openid to access the resources stored in this provider. Still I don't understand how this would work if user is already authenticated with the desktop, will they have to authenticate an other time ? What happens if they close their browser and reopen it, will they have to to do it again ?

• Sql server execute permission; failure to apply permissions

  - by WestDiscGolf

  I've just migrated from SQL2000 to SQL2008 and I have started getting an execute permission issue on a stored proc which uses sp_OACreate. The rest of the system works fine with the db login which has been setup and added to the database. I've tried: USE master GO GRANT EXEC ON sp_OACreate TO [dbuser] GO But this fails with the following error: Msg 15151, Level 16, State 1, Line 1 Cannot find the user 'dbuser', because it does not exist or you do not have permission. I'm logged into the server as sa with full permissions. I can execute a similar sql statement and apply the permissions to a server role, however not a login/user. How do I apply the changes to the specific user/login? I can apply the permissions to the public role and it resolves my issue; however this seems to be a security issue to me which I don't really want to apply to the live server.

• Advice Needed on Development of ConnectionWizard Custom Control

  - by SidC

  I have the need for an ASP.NET custom server control that will check the web.config file for a connectionstring name, prompt the user to create said connectionstring if not present, and execute create table stored procedures using the connection. This control will be embedded into a webpart for use in a WSS3.0 solution. Can anyone suggest some good tutorials on creating this type of control - specifically addressing use of connectionstrings? What methods/classes do I need to setup? Should I use the p&p data application block for this project? Thanks, Sid

• Question about SSL Certificate.

  - by smwikipedia

  Hi experts, I am trying to make a SSL connection to a web site. Each time I enter the https:// address and press enter, the IE8 prompts me to select the Certificate (Client Certificate) to send to the server. I got 2 certificates to choose from. And they are stored in the IE8 - Internet Options - Content - Certificates - Personal. Since my server and client are the same machine, I want to use a single certificate for both server and client. And this certificate is a IIS generated self signed certificate. I do the following steps: 1- Generate a self-signed-cert in IIS; 2- Bind my site to https and choose the above self-signed-cert 3- Import the self-signed-cert at the IE8 - Internet Options - Content - Certificates - Personal. Then I use the https link to access my page, it is still prompts me to choose a certificate. But I cannot see my newly imported self-signed-cert. Why?

• What are some ways to identify a logged in user on the web?

  - by farinspace

  Here is the scenario: There are 5 websites (different domain names) that need to share a session. I am using a bit of code on each site which returns a "blank.gif" image and at the same time sets the session (syncing it up to the current session). Each of the sites calls a session-img from each of the other sites. Also, all sites have access to the same database (where the session is stored). This works great on FF and Chrome, but not on IE (or Safari PC)... I need to come up with an alternative method to keep a session active? The app is a small custom CMS, so really only 2-3 people will be using it. I can probably identify user logins by IP and then continue to check for the IP accross all sites... Is there something more granular such as a computer uuid that i can check for?

• PHP> Sort query results by name while letting each letter be on the top sometimes

  - by Don

  Hi, I'm currently working on a site that will display a list of online shops, Each shop will be stored on my database and I'll be using PHP to select and display them. But since those shops will pay me, I want to let each shop to be on the top of the list sometimes, (for example if the shop name starts with a "Z", they will probably complain for being on the bottom of the list all the time, so I want to keep it fair). So I thought about letting each letter be on the top of the list for an hour, but i have no idea how to do that.. Is that even possible? Thanks in advance!

• Typed DataSet connection - required to have one in the .xsd file?

  - by Kyralessa

  In the .xsd file for a typed DataSet in .NET, there's a <Connections> section that contains a list of any data connections I've used to set up the DataTables and TableAdapters. There are times when I'd prefer not to have those there. For instance, sometimes I prefer to pass in a connection string to a custom constructor and use that rather than look for one in settings, .config, etc. But it seems like if I remove the connection strings from that section (leaving it empty), or remove the section entirely, the DataSet code-generation tool freaks out. Whereas if I don't remove them, the DataSet gripes when I put it in a different project because it can't find the settings for those connection strings. Is there any way I can tell a typed DataSet not to worry about any connections? (Obviously I'll have to give it a connection if I change any TableAdapter SQL or stored procs, but that should be my problem.)
