  • How do I save user specific data in an asp.net site?

    - by Greg McNulty
    I just set up user profiles using asp.net 3.5 using wvd. For each user I would like to store data that they will be updating every day. For example, every time they go for a run they will update time and distance. I intend to allow them to also look up their history of distance and time from any past date. My question is, what does the database schema usually look like for such a set up? Currently asp.net set up a db for me when I made user profiles. Do I just add an extra table for every user? Should there be one big table with all users data? How do I relate a user I'd to their specific data? Etc.... I have never done this before so any ideas on how this is usually done would be very helpful. Thank you.

  • Mac OS X - run shell script from the desktop GUI

    - by dreftymac
    You can create a shell script or a Python or Ruby script and run it on the Mac by using "Terminal" ... if you have Finder open, and you click on the icon for the file containing the source code of a saved shell script, is there a way to have that script run, instead of opening in my text editor ?

  • Java Interfaces

    - by Mandar
    I have a doubt.. Why do we need interfaces ? Can't we acheive the same effect by writing the implementation directly in the class? It would be great if you could illustrate your point with an example. Thanks in advance.

  • Motion detection information

    - by dotnetdev
    Hi, I know the AFORGE.NET API has motion detection algorithms, but what would be a good book to learn these algorithms with C# samples (the AFORGE.NET code is complex and not commented enough to help). Thanks

  • Programmatically change an EditorGrid's cell value

    - by Snowright
    Hi, I have an Editor Grid where if a specific cell is in focus (is being edited), a window containing a tree panel pops up allowing the user to choose a node from the treepanel as the new value of the cell. This way, the user isn't actually editing the cell in question, but is using the window to choose the new value. However, I am having difficulties setting the value of the cell in question programmatically. Below is the code I use to set the grid up, including the column model that chooses what editor to use for a cell depending on the value type: var editorCM = new Ext.grid.ColumnModel({ //config ,editors : { //rest of editors 'id' : new Ext.grid.GridEditor(new Ext.form.TextField({readOnly : true})) } ,getCellEditor : function(col, row) { //choose editor depending on the type value of a cell } }) var editorGrid = new Ext.grid.EditorGridPanel({ //rest of config ,cm : editorCM }) Below is my code to change the cell's value once the user chooses from the treepanel. function submitNode(newValue) { var temp = editorGrid.GetSelectionModel().getSelectedCell(); //returns array containing column and row position of selected cell, which value we want to change. //temp[1] = column index, temp[0] = row index //Gets the cell editor at specific position and sets new value for that cell editorGrid.getColumnModel().getCellEditor(temp[1], temp[0]).setValue(newValue); } I've also tried a few other ways (all including setValue(newValue)), but have come up empty handed. I've looked through the API and the ExtJS forums for any clue but have also come up empty handed.

  • What is the fastest way to compare two list of items?

    - by edude05
    I have two folders with approximately 10,000 files each. I'd like to write a script or program that can tell me if these folders are in sync and then tell me what files are missing from each to make them in sync. Therefore, after generating a list of files, what is the fastest algorithm to sort them for unique files? What I'm thinking right now is comparing the first file on each list then if they are different remove one until they are the same, then remove both from the list (because they are not unique.) Is there a faster algorithm then this?

  • Why doesn't my form post when I disable the submit button to prevent double clicking?

    - by John MacIntyre
    Like every other web developer on the planet, I have an issue with users double clicking the submit button on my forms. My understanding is that the conventional way to handle this issue, is to disable the button immediately after the first click, however when I do this, it doesn't post. I did do some research on this, god knows there's enough information, but other questions like Disable button on form submission, disabling the button appears to work. The original poster of Disable button after submit appears to have had the same problem as me, but there is no mention on how/if he resolved it. Here's some code on how to repeat it (tested in IE8 Beta2, but had same problem in IE7) My aspx code <%@ Page Language="C#" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <script language="javascript" type="text/javascript"> function btn_onClick() { var chk = document.getElementById("chk"); if(chk.checked) { var btn = document.getElementById("btn"); btn.disabled = true; } } </script> <body> <form id="form1" runat="server"> <asp:Literal ID="lit" Text="--:--:--" runat="server" /> <br /> <asp:Button ID="btn" Text="Submit" runat="server" /> <br /> <input type="checkbox" id="chk" />Disable button on first click </form> </body> </html> My cs code using System; public partial class _Default : System.Web.UI.Page { protected override void OnInit(EventArgs e) { base.OnInit(e); btn.Click += new EventHandler(btn_Click); btn.OnClientClick = "btn_onClick();"; } void btn_Click(object sender, EventArgs e) { lit.Text = DateTime.Now.ToString("HH:mm:ss"); } } Notice that when you click the button, a postback occurs, and the time is updated. But when you check the check box, the next time you click the button, the button is disabled (as expected), but never does the postback. WHAT THE HECK AM I MISSING HERE??? Thanks in advance.

  • Is there a bash shortcut for traversing similar directory structures?

    - by Steve Weet
    The Korn shell used to have a very useful option to cd for traversing similar directory structures e.g. given the following directorys /home/sweet/dev/projects/trunk/projecta/app/models /home/andy/dev/projects/trunk/projecta/app/models Then if you were in the /home/sweet.... directory then you could change to the equivalent directory in andy's structure by typing cd sweet andy So if ksh saw 2 arguments then it would scan the current directory path for the first value, replace it with the second and cd there. Is anyone aware of similar functionality in bash. EDIT 1 Following on from Michal's excellent answer I have now created the following bash function called scd (For Sideways cd) function scd { cd "${PWD/$1/$2}" } EDIT 2 Thanks to @digitalross I can now reproduce the ksh functionality exactly with the code from below (With the addition of a pwd to tell you where you have changed to) cd () { if [ "x$2" != x ]; then builtin cd ${PWD/$1/$2} pwd else builtin cd "$@" fi }

  • Modify Jquery UI slider control

    - by Jean-Yves Deman
    I use the Jquery UI slider control. My slider has a width of 200px. I would like the center of my left handle is shifted 14px to the right and the center of my right handle is offset to the left of 14px. So, my good slider will more than 172px (200-14-14). The background-image measure good 200px. The length of 14px is calculated as follows: width of the handle (28px) / 2. Can you help me solve this mystery? Thank you in advance. .ui-slider .ui-slider-handle { width:28px; height:28px; background:url(images/bulle.png) no-repeat 0 0; overflow: hidden; position:absolute; margin-left:0px; top: -7px; border-style:none; cursor:help; }? I use "margin-left:0px;" to delete the "margin-left:-14px" by default. But, my right handle spring 28px to the right ! Help me please !

  • Views jump during ViewDidLoad

    - by Jon-Paul
    Hi, I have a custom button, subclassed from UIButton that is initialised as below (obviously all the button does is use a custom font). @implementation HWButton - (id)initWithCoder:(NSCoder *)decoder { if (self = [super initWithCoder: decoder]) { [self.titleLabel setFont:[UIFont fontWithName: @"eraserdust" size: self.titleLabel.font.pointSize]]; } return self; } So far so good. But when I use the custom class in my nib and launch the app, the button initially displays for a split second as tiny with small text, then grows. So the outcome is what I want, but I don't want to see the transition. Can anyone put me right? Thanks. JP

  • Multiple Controls on a Page with Multiple Instances of Javascript

    - by mattdell
    I have created a Web Control in ASP for use in integrating with Telligent CommunityServer. The control is written in ASP with some 10 lines of C# backend for controlling visibility of the UI elements based on permissions, but I'd say 90% of the functionality is straight-up Javascript. The control works beautifully, until you drop two instances of the Control on the same page--since they reference the exact same Javascript functions, only one control works. How can I take this functionality that I have, this 1200 lines of Javascript, and make it so that each instance of the control can reference its each unique instance of Javascript?

  • How to put a background image on GridBagLayout

    - by Loligans
    I am trying to work with layout managers for the first time, and they are just kicking me in the teeth. I am trying to make a background image and then put buttons on top, using GridBagLayout, if there is a a better layoutmanager please do tell. As for trying to learn how to use layout managers, its very difficult and any learning references would also be much appreciated. This is what it looks like currently, I can get the frame to show the full image, but when i use gridlayout manager, it does that public void addComponentsToPane(Container pane){ BackgroundImage image = new BackgroundImage(); JButton button1, button2, button3, button4, button5; pane.setLayout(new GridBagLayout()); GridBagConstraints c = new GridBagConstraints(); if(shouldFill){ c.fill = GridBagConstraints.NONE; } button1 = new JButton("Button 1"); if (shouldWeightX) { c.weightx = 0.5; } c.fill = GridBagConstraints.HORIZONTAL; c.gridx = 1; c.gridy = 0; button1.setOpaque(false); pane.add(button1, c); button2 = new JButton("Button 2"); c.fill = GridBagConstraints.HORIZONTAL; c.weightx = 0.5; c.gridx = 0; c.gridy = 0; button2.setOpaque(false); pane.add(button2, c); button3 = new JButton("Button 3"); c.fill = GridBagConstraints.HORIZONTAL; c.weightx = 0.5; c.gridx = 2; c.gridy = 0; button3.setOpaque(false); pane.add(button3, c); button4 = new JButton("Long-Named Button 4"); c.fill = GridBagConstraints.HORIZONTAL; c.ipady = 40; //make this component tall c.weightx = 0.0; c.gridwidth = 3; c.gridx = 0; c.gridy = 1; pane.add(button4, c); button5 = new JButton("button 1"); c.fill = GridBagConstraints.HORIZONTAL; c.ipady = 0; //reset to default c.weighty = 1.0; //request any extra vertical space c.anchor = GridBagConstraints.PAGE_END; //bottom of space c.insets = new Insets(10,0,0,0); //top padding c.gridx = 1; //aligned with button 2 c.gridwidth = 2; //2 columns wide c.gridy = 2; //third row pane.add(button5, c); c.ipadx = 800; c.ipady = 400; pane.add(image, c); } This is what i'm trying to make it look like

  • Did IE8 lose the document.frames collection?

    - by Nick
    Hey all.. I noticed that an application I am maintaining was giving me a javascript error in IE8 and FF. The script was trying to get a collection of frame elements: document.frames This always returned 'undefined'. I placed a watch on the document object and noticed that this collection does not seem to be a member of the document object in IE8. I think this was always the case in FF but this same code works in older versions of IE. Has this been removed? -Nick

  • webOS style view switching on iPhone app

    - by Taylor Satula
    Hello, I have been working with a iPhone app that I would like to have switch views like the Palm Pre does for multitasking. I know the usual way of switching views by using the black bar at the bottom of the app but the app I am working on does not lend itself to having a big black bar in the way (see attached picture #1). I guess my question is, how do I shrink the current view (Current Location window) and show other views on the sides? (see attached picture #2) Then be able to swipe left and right to view other views. I have no idea how to do this and would be eternally grateful if someone could help me out with this. http://www.threepixeldrift.com/images/deep-storage/webOScardapp1.jpg http://www.threepixeldrift.com/images/deep-storage/webOScardapp2.jpg

  • Running shell scripts with sudo through my web app

    - by nfm
    I have some functionality that interfaces with the server's OS in my web application. I've written a bash script and am able to run it from within my app. However, some functionality of the script requires superuser privileges. What is the most sane way to run this script securely? It is being passed arguments from a web form, but should only be able to be called by authenticated users that I trust not to haxxor it.

  • OptionParser python module - multiple entries of same variable?

    - by jduncan
    I'm writing a little python script to get stats from several servers or a single server, and I'm using OptionParser to parse the command line input. #!/usr/bin/python import sys from optparse import OptionParser ... parser.add_option("-s", "--server", dest="server", metavar="SERVER", type="string", help="server(s) to gather stats [default: localhost]") ... my GOAL is to be able to do something like #test.py -s server1 -s server2 and it would append both of those values within the options.server object in some way so that I could iterate through them, whether they have 1 value or 10. Any thoughts / help is appreciated. Thanks.

  • How can I improve this search usability?

    - by Craig Whitley
    This is the first real programming attempt of mine, and theres some major flaws. It's a learning project, and I'm currently re-writing the entire thing as my php is is really messy. I really want to get an idea on how I can improve the actual usability and accesibility of the site at the same time though - so I know how to implement it correctly. The website is basically a comparison website for gameserver hosting. As I mentioned, its a learning project and I don't actually expect any revenue from it. At the moment theres only test data in it, so in the game input box select either 'Battlefied Bad Company 2' or 'Call of Duty 4: Modern Warfare' and ignore the actual search results. http://www.laglessfrag.com I wasn't really sure how to work the search functionality. Basically when you click a game in the drop down box, it sends an ajax request and finds all the locations available to that specific game in the database. After selecting the country theres another ajax to find all the citys available to the game in that country - which gives me the two unique identifiers I need to create the search results. One major and fundamental flaw is that without javascript enabled, the site ceases to function. I'll overcome that in the next re-write, but without the ajax functionality stopping the user 'going wrong' - how can I implement a search that requires two fields without creating extra steps in new pages after form submissions? I'm also no designer so my whole layout and css is a bit rubbish, but this was mainly a learning project as I'm interested in applications / programming rather than design. It's also slow as its on shared hosting, but if I can get it to work correctly then I'm not impartial to chucking a bit of money at it for faster hosting and maybe a bit of advertising and seeing where it goes (if anywhere!). Any info appreciated.
