Using colon syntax and variables in Sass

- by corroded

I am still using the old colon syntax (I prefer it more than the bracket syntax) and this particular code: a.button-link +box($main-color) +border-radius(5px) :background :color $main-color :color #fff :padding 5px generates a warning like so: DEPRECATION WARNING: On line 12, character 3 of '/Users/eumir/rails_apps/dxconnect/app/ stylesheets/partials/utilities/_link-styles.sass' Setting properties with = has been deprecated and will be removed in version 3.2. Use "background: $main-color" instead. I tried that but my background color still doesn't show up. Any help on this please? Thanks!

iphone tabbar with custom buttons and scrollvie

- by chunjai

i'm trying to get a tab bar effect not unlike russel quinn's 'creative review' app. the tabbar swipes across, which i have figured out, but the tabbar style itself is unlike anything i've seen on the iphone (though it looks so simple!). it has square buttons with a space between, and each button has a select/active/inactive state. i'm having a hard time seeing how this can be tabbar, but i don't know any other way. can someone explain this? here's the example :: http://bit.ly/c8CeBC. any help is appreciated.

jQuery: datepicker - Calendar activated by the icon and the date field at the same time

- by Ricardo Zea

Hello, I've already looked around but couldn't find the exact solution/problem I'm having right now. All I want is to have the calendar appear either by clicking on the calendar icon AND from the text field in which the date appears when selecting a date. Right now, after trying different properties, I can only have the calendar appear by one or the other, but not both: the icon and the field. This is the code I'm using to activate it via the icon: $("#datepicker").datepicker({ showOn: 'button', buttonImage: 'images/icon-calendar.gif', buttonImageOnly: true, changeMonth: true, changeYear: true, showAnim: 'slideDown', duration: 'fast' }); Is there a way to have the calendar appear by clicking on the icon AND the field as well? Thanks.

Threading and pcap issues.

- by cftmon

I have a GUI program that allows a user a scan a network, the issue is that when the pcap_loop function is called, my GUI program becomes unresponsive.(the pcap_loop blocks the current thread). When i try to use pthreads, i got a SIGSEGV fault at the pcap_loop function.Why?It's as if the thread can't see the procPacket function itself. void procPacket(u_char *arg, const struct pcap_pkthdr *pkthdr, const u_char *packet) { //show packets here } void* pcapLooper(void* param) { pcap_t* handler = (pcap_t*) param; pcap_loop(handler, 900 ,procPacket, NULL ); } //some function that runs when a button is pressed //handler has been opened through pcap_open_live pthread_t scanner; int t = pthread_create(&scanner,NULL,&pcapLooper, &handler ); if(t) { std::cout << "failed" << std::endl; } pthread_join(scanner,NULL); //do other stuff.

Using (void)awakeFromNib

- by MN

I am trying to run an action when the application starts. The action checkAtStart is supposed to display an alert if there is no text in field1 and hide startView if there is text in field1. checkAtStart works fine if assigned to a button, but when I try to run it using (void)awakeFromNib, the alert will display no matter what and startView will never hide. Its probably something really simple that I'm forgetting. Any help is appreciated! Here is my code: - (void)awakeFromNib { [self checkAtStart:self]; } - (IBAction)checkAtStart:(id)sender { if (field1.text == nil || [field1.text isEqualToString:@""]) { NSString *msg = nil; msg = nil; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Test Message" message:@"Test Message" delegate:self cancelButtonTitle:@"Close" otherButtonTitles: nil]; [alert show]; [alert release]; [msg release]; } else { startView.hidden = YES; } }

Adding a new view to a Window-based app (re: MapKit tutorial)

- by blackkettle

I'm trying add a new view in a window-based application but not really getting anywhere. I've been going through a great MapKit tutorial lately, http://mithin.in/2009/06/22/using-iphone-sdk-mapkit-framework-a-tutorial/ and have successfully set it up and added some further buttons and customizations. However I've gotten stuck at what I assume ought to be a brain-dead simple step. I have added a toolbar to the bottom of the app, and a 'settings' style button. Following this I created a SettingsViewController complete with it's own view. Now I'd like to connect them but I've had absolutely no luck trying to figure out how to do this. I've also gone through several other good tutorials lately, http://miketeo.net/wp/index.php/2008/08/31/simple-iphone-tutorial-part-1.html http://blog.webscale.co.in/?p=228 http://www.iphonesdkarticles.com/2009/01/uitableview-searching-table-view.html but I've gotten lost trying to tie these two bits together. I'm sure it is quite trivial to link these two items but I've had no luck.

Faking user interaction on CMS

- by Leocer

I'm working with a CMS and need to import data to it using typical html forms. The data itself is in csv files with one page per row. Such is the CMS that importing directly to db isn't possible due to the complexity of the design. It's pretty important that i "fake" usual user interaction because the CMS does a lot of background work that's crucial for the import. Basically, for each row in the csv file, I need to copy a csv column to a html textfield, or select a checkbox, or click a certain button. One major issue is mapping the data in the csv to actions in the CMS. So if one column contains the string 'foobar' is really means "set the firstName dropdown widget to 'foobar'". Is there a tool to automate this? I´ve been looking at AutoHotKey, Selendium, Web-Harvester and many other tools but I'm not convinced they are the correct tools. The main problem is being able to interact with the html pages in a easy way.

WPF buttons same/recommended width

- by rwallace

Suppose you have a window with multiple buttons such as Ok/Cancel or Yes/No/Cancel. All the buttons need to be the same width. Obviously this could be done by just guessing a number and hardwiring all of them to that number. Is there a better way to do it, one that would take into account preferred/recommended sizes (just how wide should an Ok button be anyway? This is not a rhetorical question, I actually don't know the answer!), what's needed by the text of the longest caption, what happens if the font size is increased etc?

calling a method on the parent page from a user control

- by Kyle

I am using a user control that I created (just a .cs file not an .ascx file), that does some magic and depending on a value generated by the control, I need it to do something on the parent page that is 'hosting' the control. It needs to call a method under certain circumstances (method is on the parent control). the control is placed on the parent page like so: <customtag:MyControl ID="something" runat="server" /> I'm dynamically creating buttons etc on the control itself but when a button is clicked, let's say for example that there's a text box on the control and if the value of the textbox is "bob" it needs to call a method on the page that's housing the control...how can I accomplish this?

Handle leaks with .NET System.Threading.Thread class

- by Mahno

I've a problem that number of Handles in my app is continuously growing. I did the debugging and recognize that this is caused by System.Threading.Thread class which is used for some routine. To simplify the debugging I’ve created a sample .NET application: ... private void button1_Click(object sender, EventArgs e) { Thread t = new Thread(DoWork); t.Start(); } public void DoWork(object parameter) { // Do something... } ... Each time I’m clicking the button, a thread is created using System.Threading.Thread class. The problem is that looks like the thread do not frees Handles because each click cause number of Handles growing by ~5. The question is: how can I manually free all Handles created by System.Threading.Thread class? Thanks in advance.

Java Swing app hangs when run in normal mode but runs fine in debug mode

- by snocorp

I am writing a basic Java application with a Swing front-end. Basically it loads some data from a Derby database via Apache Cayenne and then displays it in a JTable. I'm doing my development in Eclipse and I don't think it's important but I'm using Maven for dependencies. Now this works fine when I run using Debug but it seems to hang the display thread when I use the Run button. I've done a thread dump and I'm not 100% certain but everything looks good. I used Java VisualVM and the threads look fine there as well. Strangely it seems to work intermittently. It's pretty consistent though and easy to reproduce. If anyone has any ideas, I'm all out of them.

Why shouldnt i use flash again?

- by acidzombie24

I heard many times i should avoid flash for my website. Yet no one has told me a good reason. I searched for reasons and i see many that are not true (such as text in flash are not indexable by search engines) or may not necessarily be true or significant enough (eating more bandwidth. Would a JS equivalent be bigger or smaller?). My site uses flash to playback sound (m4a). I dont have to worry about indexing, the back button not working, etc. But i have feeling there may be other reasons. What are reasons i shouldnt use flash on my website. I'll note one, the fact iphone/itouch and mobile devices does not support it. Not a big deal for most sites and is obvious. What are reason to avoid flash on my site?

Flex 3.0 Drag and Drop

- by C-Man

Hi all! I have encountered a problem in a Flex application. I have implemented drag and drop support from a List to a Canvas, and I DragManagers doDrag() - with.a proxy-image. In my custom DragDrop event handler, i place a new item on the Canvas. I use the event.localX/localY to position the new item. It is working ok, but the problem is that I want the "new" image to appear exactly where the proxy-image is when i release the mouse button (x/y -wise). Can I somehow get the proxys X,Y location. I thought that DragManager would have a reference to it but I can´t find it. Thanks /C

ImageAdapter and ListView (java.lang.OutOfMemoryError: bitmap size exceeds VM budget)

- by theDude

Hi, I'm using ListView to display images which I provide through an ImageAdapter class. it works great on my device (and on many other devices which I tested it on), but somehow when I'm using the emulator and I'm long-pressing the up/down button - I'm getting an outOfMemory error after 10-15 seconds. I tried clearing cache, canceling cache, etc. - nothing helped. I know this crash is pretty rare (i couldn't reproduced it on any "real" device), but I can see on DDMS that "GC freed" are getting bigger during that long press and I can't find a way to clear them. Any help will be appreciated, Tnx.
