  • How to automatically mount a Windows shared folder on every boot up?

    - by Zabba
    I am able to access Windows' shared folder from Ubuntu 10.10 Nautilus like so: Type into the Location Bar : smb://box/projects Now, I can see the folder in Nautilus, create/read files in it. Also, on desktop I get a folder called "projects on box". But, that folder on the desktop goes away when I reboot. So, I thought that I can automount the Windows' shared projects folder by adding this to my fstab: //box/Projects /home/base/Projects smbfs rw,user,username=jack,password=www222,fmask=666,dmask=777 0 0 (base is my user name on Ubuntu) Now, I get a folder called "Projects" in my home folder after boot up, but it is empty (cannot see the same files that I can see in Nautilus). What's am I doing wrong? Some more detail: This is what I see of the Projects folder when I do ls -l in my home folder: ... drwxr-xr-x 2 root root 4096 2011-01-01 10:22 Projects drwxr-xr-x 2 base base 4096 2011-01-01 09:06 Public ... Note the two "roots". Is that somehow the problem?

  • size of an image

    - by Mike
    From times to times I have to know the width and height of images. I am using the following code: UIImage *imageU = [UIImage imageWithContentsOfFile:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"myImage.png"]]; CGFloat imageW = CGImageGetWidth(imageU.CGImage); CGFloat imageH = CGImageGetHeight(imageU.CGImage); My question is that if it is there any other way to know the width and height of an image, in pixels, without having to load the image on a variable, that's probably consuming memory. Can the dimensions be read from the file directly without loading the whole image? thanks.

  • Cell Dequeue problem when table inside another table's cell content view

    - by Shailesh Kanzariya
    I am using two table views (Main Table and Sub Table), one table inside other's cell. I am adding Sub Table in Main Table's cell content view. I am also using different Cell Identifier for both table cells. Now, issue is : When - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath is called, very first time cell of Main Table is generated and when I scroll up/down they all are just dequeued, so it is expected and standard behavior and working fine. But, cell of Sub Table is getting created/allocated every time. It is not dequeued as it should be. I guess, its happening because Sub Table is part of Main Table's Cell Content view. But not sure and don't know how to resolve it. Can somebody help me to find the solution?

  • MP3 files downloaded from cloud incomplete/cut off (Android app)

    - by rudefyet
    I noticed today on my phone (Droid X running Android 2.2.1) that when streaming the Ubuntu One app would skip to the next song before the previous one had finished. Looking into it, one of the mp3s downloaded from the server was only 2.5MB instead of 4.2MB as it shows on the server itself via one.ubuntu.com. It's happened with multiple tracks today (I remember it happening once the first time I used the app too but shrugged it off as a glitch). The app itself shows a star on the playlist item indicating the file was downloaded even though it was apparently cut off for some reason, perhaps lack of good cell coverage, or some sort of dropped connection. It seems like the latter may be happening and instead of showing an error or retrying it just stops and shows the download is complete.

  • "reset" cells after changing orientation

    - by Christian
    Hi, I added the interfaceOrientation to my app. It works fine concerning the views. Some of the table-cells I defined by CGRects to position the text in the cell. In portrait-mode the cell is 300px long, in landscape-mode 420px. I use the following code to change the CGRects depending the orientation: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { if (self.interfaceOrientation == UIDeviceOrientationPortrait) { NSString *currentLanguage = [[NSString alloc] initWithContentsOfFile:[NSHomeDirectory() stringByAppendingPathComponent:@"/Documents/sprache.txt"]]; static NSString *TableViewTableCellIdentifier = @"TableViewTableCellIdentifier"; UITableViewCell *cell = (UITableViewCell *) [tableView dequeueReusableCellWithIdentifier:TableViewTableCellIdentifier]; CGRect cellRect = CGRectMake(0, 0, 300, 175); cell.backgroundColor = [UIColor darkGrayColor]; cell = [[[UITableViewCell alloc] initWithFrame:cellRect reuseIdentifier:TableViewTableCellIdentifier] autorelease]; CGRect keyLabelRect = CGRectMake(0, 5, 5, 20); UILabel *keyLabel = [[UILabel alloc]initWithFrame:keyLabelRect]; keyLabel.tag = 100;......... } else { NSString *currentLanguage = [[NSString alloc] initWithContentsOfFile:[NSHomeDirectory() stringByAppendingPathComponent:@"/Documents/sprache.txt"]]; static NSString *TableViewTableCellIdentifier = @"TableViewTableCellIdentifier"; UITableViewCell *cell = (UITableViewCell *) [tableView dequeueReusableCellWithIdentifier:TableViewTableCellIdentifier]; CGRect cellRect = CGRectMake(0, 0, 450, 175); cell.backgroundColor = [UIColor darkGrayColor]; cell = [[[UITableViewCell alloc] initWithFrame:cellRect reuseIdentifier:TableViewTableCellIdentifier] autorelease]; CGRect keyLabelRect = CGRectMake(0, 5, 5, 20); UILabel *keyLabel = [[UILabel alloc]..... My problem is, when the table is visible and the orientation is changed, I need to scroll to see the new "layout". How can I manage to "reload" the view after changing the orientation?

  • How to write to an XML file from the iPad OS?

    - by user345474
    I am developing an app for IPad, and I need to modify several attributes in a XML file at runtime. I found the class NSXMLDocument, http://developer.apple.com/mac/library/documentation/cocoa/reference/foundation/Classes/NSXMLDocument_Class/Reference/Reference.html But I haven't been able to import it to my project. Is this class not available for IPhone/IPad development? Is there some other approach I can consider? I read about libxml library. Is it my answer or there is a better approach?

    - by user950731
    I am using Ubuntu 12.04 on a Dell Studio 15 and so far am really impressed. I could not find a solution for my problem by googling. The fonts on some websites do not have proper spacing. they overlap and are very hard to read that way. I am using the Ubuntu standard fonts and have not changed them after installing. Here is a screencap that shows my problem. The problem occurs in Firefox and Chrome the same way, and on the same websites. Thanks for your help. Best regards el

    - by 4thSpace
    I need to format text in a label like this: username: some text from this user. This will create additional lines of text that will go on and on and on. Where "username" is bold. This will go into a UILabel, which is in a custom table cell. Is there a way to get this type of layout?

  • Users adding views

    - by adamprocter
    I have created a main page (myAppViewController) and a add page rect button I have also created a page template (TemplateAViewController) all set up in Interface builder. I would like users to be able to add as many templates themselves and then page through them. I am not sure where to start. I can create views programmatic like so -(IBAction)createnewpage : (id) sender { myAppViewController *viewcontroller = [[myAppViewController alloc] initWithNibName:@"TemplateAViewController" bundle:[NSBundle mainBundle]]; [[self view] addSubview:viewcontroller.view]; } I then want to be able to navigate through these views- I guess I need to create a navigation controller to do this ?

  • Stubborn UIButton

    - by Mike
    I have a UIButton that is supposed to be disabled during certain phases. So, when this happens I do [myButton setEnabled:NO]; This is perfect because the button stays grayed and if clicked will not trigger its action, but... when the button is clicked even grayed, it enables again and a second click will trigger its actions (???????!!!!!!!!!!). How can that be? If the button is disabled it is supposed to be "part of the background", i.e., an image without any action. I have tried to make the button vanish using alpha but even if you click on the empty spot, it reappears after the first click and then can trigger actions after the second click... (????) Am I missing something?

  • cocoa - referencing a method on the parent

    - by Mike
    I had a method on my main view controller named "calculateThis". This method was run, obviously, as int newValue = [self calculateThis:myVariable]; when I run it from inside the view controller. Then I created a static class and I need to run this method from there. How do I reference this method from that class using just relative references, as super, superview, delegate, etc. I cannot use the class name defined on the delegate because this static class is used in several apps of mine.

  • Why do I need to republish a file when I update it?

    - by user13089
    The story is: I am coding a program and at the same time, i want to share it with my group members using ubuntu. They don't have an Ubuntu One account and what I do is to publish the file and my friends just get the link and the file. But, strangely or not, every time I upload a new version of this file (I add more code and save it), the used link seems to be "outdated" and I need to publish the same file again and to get a new link every time i modify the same file. Couldn't it be possible to save a new version of your file and the same link just "points" to the newer version?

  • Why am I losing precision when populating an NSDecimalNumber with a double?

  • UbuntuOne: how to sync folders on different partitions (symlink?)

    - by user37155
    I use Ubuntu One to synch my home/Documents folder among more computers. On a portable tablet I have set the Documents folder in a separate Fat32 partition named sda6, and I made it default documents folder with Ubuntu Tweaks. How do I synchronize it with my /Documents cloud ? I tried to link /sda/Documents in my home folder but it didn't succeed: UbuntuOne still tries to set an own Documents folder and doesn't let me sync the linked folder with the cloud. What can I do, would please anyone help me ? Greetings, Francesco
