• Trying to verify understanding of Foreign Keys MSSQL

  - by msarchet

  So I'm working on just a learning project to expose myself to doing some things I do not get to do at work. I'm just making a simple bug and case tracking app (I know there are a million this is just to work with some tools I don't get to). So I was designing my database and realized I've never actually used Foreign Keys before in any of my projects, I've used them before but never actually setting up a column as a FK. So I've designed my database as follows, which I think is close to correct (at least for the initial layout). However When I try to add the FK's to the linking Tables I get an error saying, "The tables present in the relationship must have the same number of columns". I'm doing this by in SQLSMS by going to the Keys 'folder' and adding a FK. Is there something that I am doing wrong here, I don't understand why the tables would have to have the same number of columns for me to add a FK relationship between the tables?

• Running a stored procedure in a SqlDataSource on button click

  - by Gapton

  I am building a C# ASP.NET page where I want to call a stored procedure in a database. I have setup a SqlDataSource which points to the stored procedure. Parameters are obtained from the Web's control directly (TextBox) I have a button, when the user clicks it it should run the stored procedure, so I was going to add code like this : mySqlDataSource.run() or mySqlDataSource.exec() or mySqlDataSource.storedProcedure() but of course none of these methods exist. How do I initial the stored procedure? and how do I get the value returned by the stored procedure please? Thank you!

• ASP Classic Named Parameter in Paramaterized Query: Must declare the scalar variable

  - by My Alter Ego

  I'm trying to write a parameterized query in ASP Classic, and it's starting to feel like i'm beating my head against a wall. I'm getting the following error: Must declare the scalar variable "@something". I would swear that is what the hello line does, but maybe i'm missing something... <% OPTION EXPLICIT %> <!-- #include file="../common/adovbs.inc" --> <% Response.Buffer=false dim conn,connectionString,cmd,sql,rs,parm connectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Data Source=.\sqlexpress;Initial Catalog=stuff" set conn = server.CreateObject("adodb.connection") conn.Open(connectionString) set cmd = server.CreateObject("adodb.command") set cmd.ActiveConnection = conn cmd.CommandType = adCmdText cmd.CommandText = "select @something" cmd.NamedParameters = true cmd.Prepared = true set parm = cmd.CreateParameter("@something",advarchar,adParamInput,255,"Hello") call cmd.Parameters.append(parm) set rs = cmd.Execute if not rs.eof then Response.Write rs(0) end if %>

• Best practice -- Content Tracking Remote Data (cURL, file_get_contents, cron, et. al)?

  - by user322787

  I am attempting to build a script that will log data that changes every 1 second. The initial thought was "Just run a php file that does a cURL every second from cron" -- but I have a very strong feeling that this isn't the right way to go about it. Here are my specifications: There are currently 10 sites I need to gather data from and log to a database -- this number will invariably increase over time, so the solution needs to be scalable. Each site has data that it spits out to a URL every second, but only keeps 10 lines on the page, and they can sometimes spit out up to 10 lines each time, so I need to pick up that data every second to ensure I get all the data. As I will also be writing this data to my own DB, there's going to be I/O every second of every day for a considerably long time. Barring magic, what is the most efficient way to achieve this? it might help to know that the data that I am getting every second is very small, under 500bytes.

• Geocoding service for a startup?

  - by Sologoub

  I'm working on an idea for a service that uses geocoded data (lat/lng) form a US address. Google maps API v3 has been awesome, until I read the terms of service and acceptable uses a little closer. The problem is that the terms seem to prohibit use of the maps API for any commercial use where the site is not freely accessibly to the public, such as a subscription based service. The alternative offered is Google Maps API Premier, but at $10,000 per year minimum, it's just not possible at this time. Same goes for services offered by Yahoo! and MS - initial fees are small for enterprises, but for a very early stage startup (not even a finished prototype yet!) it's just not doable. Geocoding process needs to be real-time and volume would be very small - user would enter address at setup time and only update it if needed. Any help is greatly appreciated!

• How do I alternate table row colors in asp.net mvc using jquery?

  - by grenade

  Probably a dumb question but I'm new to MVC and jQuery. I want to alternate the row colors of my tables and I've decided that I'm going to use jQuery to do it. I know that I could write an extension method (http://haacked.com/archive/2008/08/07/aspnetmvc_cycle.aspx), etc but after reading SH's comment on the article at http://haacked.com/archive/2008/05/03/code-based-repeater-for-asp.net-mvc.aspx I've picked jQuery as the solution I want to implement. I want to implement the method described at http://www.packtpub.com/article/jquery-table-manipulation-part2 but I haven't figured out where to put the initial jQuery call (eg: $(document).ready(function() {...}); Like I said, I'm new to jQuery...

• What to keep in mind when creating your own custom web services API?

  - by John Conde

  I have created a website which allows users to sign up for, and use, an online service. To help promote the website we will be have resellers who will be offering their own branded services through us. The initial plan is to allow resellers to place registration, login, and lost password forms on their own website and use an API created by us to handle these requests. I have begun outlining how I expect the API to work (and starting documenting it as well) and I want to make sure I get it right, or as close to right, as I can from the beginning as I know once you have declared a public API you want to avoid changing that API at all costs. So far I have decided: To have the user pass their account credentials with each request To require SSL for all requests What else should I be keeping in mind?

• Android WebView not respecting scaling percentage on physical devices...

  - by fiXedd

  I have a WebView which I'm trying to have scale to a certain percent on loading the page. The iPhone version of this software uses the HTML meta-tag: <meta name="viewport" content="width=320, initial-scale=0.95, maximum-scale=2.0, user-scalable=1"> Since Android's WebView doesn't seem to respect that tag I hard-coded the percent using setInitialScale(). However, the WebView is just flat-out ignoring this method call. No matter what number I put in there it shows at 100%. Ideas? Update: It's working fine in the emulator, it's only failing on my Droid (Motorola) and my G1 (HTC).

• Swing Timer in Conjunction with Possible Long-running Background Task

  - by javacavaj

  I need to perform a task repeatedly that affects both GUI-related and non GUI-related objects. One caveat is that no action should performed if the previous task had not completed when the next timer event is fired. My initial thoughts are to use a SwingTimer in conjunction with a javax.swing.SwingWorker object. The general setup would look like this. class { timer = new Timer(speed, this); timer.start(); public void actionPerformed(ActionEvent e) { SwingWorker worker = new SwingWorker() { @Override public ImageIcon[] doInBackground() { // potential long running task } @Override public void done() { // update GUI on event dispatch thread when complete } } } Some potential issues I see with this approach are: 1) Multiple SwingWorkers will be active if a worker has not completed before the next ActionEvent is fired by the timer. 2) A SwingWorker is only designed to be executed once, so holding a reference to the worker and reusing (is not?) a viable option. Is there a better way to achieve this?

• Recreating iPhone stock application with nested views

  - by john

  I am trying to create an app similar to the Yahoo Stocks app that comes on the iPhone, with the split-screen interface (table on the top, graph on the bottom). I'm struggling with the view hierarchy. What is the easiest way to implement a split-screen type of application. I basically want two views nested in a parent view. My problem is a little bit more complex because I want functionality like having a uipagecontrol (does this require another viewcontroller, or is simply implemented in the initial view controller)? To what degree do I need to use IB? I would prefer to do this all in Xcode. Thanks in advance!

• Access 2007 - Forms created on the fly

  - by glinch

  Hi There, Hopefully I can find some words of advice from somebody. Is it possible to create forms 'on-the fly' so to speak in MS-Access 2007 I have a structure of tables: tblCustomer tblQuestAns A customer may answer the questionnaire answers many times as they relate to all products. I propose to hopefully have an initial input form that will ask how many products of which there could be more than 1 eg: TV, Video (say the user selects 2) On entering that data the next form should hopefully update itself to include the list of questions eg TV Q1, Q2 Q3 - Video (1) Q1, Q2 Q3 - Video (2) Q1, Q2 Q3 Is that possible? Any point in the right direction would be appreciated. Thanks Noel

• slow record deletion with large ntext values

  - by asking

  I'm having trouble deleting some records via a stored procedure from a table in SQLServer 2008R2 that has ntext columns. The stored proc is timing out and running the query directly takes a very long time. The initial query was a straight "delete from y where x = z" and I've also tried running it in batches of 1000 with transactions but it is still slow and timing out in a stored proc. The majority of the records in the table will not be deleted each time (it's not just a once-off query but will be run other times). The ntext columns are not used in the where clause and I can't change the column types. Any suggestions on the quickest way to delete records with large ntext values? Thanks

• DropDownList selectedValue not changing display

  - by MemphisDeveloper

  I have a list of controls that I change based on an event. The controls are contained within a table that is created dynamically. I traverse through a set of controls and if it is a RadioButtonList or a DropDownList I do the following: CType(cntrl, ListControl).SelectedValue = val The radio buttons set just fine but the dropdown list doesn't reset. Can anyone tell me why. The initial table is created on the first Page Load and stored in memory. It's values are changed during the eventhandling and reposted to a MasterPage's content holder.

• Copying a mysql database from localhost to remote server using mysqldump.exe

All the examples on the internet suggest doing something like The initial mysql> is just the prompt I get after logging in. mysql> mysqldump -u user -p pass myDBName | NewDBName.out; But when I do this I get You have an error in your SQL syntax; check the manual that corresponds ... to use near 'mysqldump -u user -p pass myDBName | NewDBName.out' Since I have already logged in do I need to use -u and -p? Not doing so gives me the same error. Can you see what is wrong?

• Radial Grid Search Algorithm

  - by grey

  I'm sure there's a clean way to do this, but I'm probably not using the right keywords for find it. So let's say I have a grid. Starting from a position on the grid, return all of the grid coordinates that fall within a given distance. So I call something like: getCoordinates( currentPosition, distance ) And for each coordinate, starting from the initial position, add all cardinal directions, and then add the spaces around those and so forth until the distance is reached. I imagine that on a grid this would look like a diamond.

• Python script run via cron does not execute occassionally

• How to adjust a JScrollPane to its contained JTree

  - by spuas

  Hello, here I have a swing size question: I have a JTree which is contained inside a JScrollPane (which is contained in a custom component which extends JXPanel from swingx, but I think that has nothing to do with this question). Doesn't matter how many rows the tree has, the scrollpane is always bigger (the tree is dinamic but not designed to have many rows) but what I would like is the JScrollPane to adjust to the tree initial height and then show the vertical scroll when some of the nodes are expanded. I have tried without setting any size at all, setting tree preferred size to null and setting scrollpane preferred size to null as well but nothing changes. I DO NOT WANT to set the size manually... Is there a way to do this? Thanks

• Print stacktrace from C code with embedded lua

  If I understand this correctly, Lua by default will call the debug library "debug.traceback" when an error occurs. However, when embedding Lua into C code like done in the example here: Simple Lua API Example We only have available the error message on the top of the stack. i.e. if (status) { /* If something went wrong, error message is at the top of */ /* the stack */ fprintf(stderr, "Couldn't load file: %s\n", lua_tostring(L, -1)); /* I want to print a stacktrace here. How do I do that? */ exit(1); } How do I print the stack trace from C after the initial error?
