I want to ask : Does DAO layer do purely data access related task ? What about exception encapsulation ? Is there other pattern can be used to replace this ?

  • Removing non-breaking spaces from strings using Python

    - by dontsaythekidsname
    Hello: I am having some trouble with a very basic string issue in Python (that I can't figure out). Basically, I am trying to do the following: '# read file into a string myString = file.read() '# Attempt to remove non breaking spaces myString = myString.replace("\u00A0"," ") '# however, when I print my string to output to console, I get: Foo **<C2><A0>** Bar I thought that the "\u00A0" was the escape code for unicode non breaking spaces, but apparently I am not doing this properly. Any ideas on what I am doing wrong?

  • HipHop instead of XCache?

    - by Marco
    Would it make sense to switch to HipHop to replace XCache? It seems illogical to run both simultaneously. Is HipHop ready for primetime or should we wait several months before implementing it?

  • UINavigationBar unresponsive after canceling a UITableView search in nav controller in tab bar in a popover

    - by Mark
    Ok, this is an odd one and I can reproduce it with a new project easily. Here is the setup: I have a UISplitViewController. In the left side I have a UITabBarController. In this tab bar controller I have two UINavigationControllers. In the navigation controllers I have UITableViewControllers. These table views have search bars on them. Ok, what happens with this setup is that if I'm in portrait mode and bring up this view in the popover and I start a search in one of the table views and cancel it, the navigation bar becomes unresponsive. That is, the "back" button as well as the right side button cannot be clicked. If I do the exact same thing in landscape mode so we are not in a popover, this doesn't happen. The navigation bar stays responsive. So, the problem only seems to happen inside a popover. I've also noticed that if I do the search but click on an item in the search results which ends up loading something into the "detail view" of the split view and dismissing the popover, and then come back to the popover and then click the Cancel button for the search, the navigation bar is responsive. My application is a universal app and uses the same tab bar controller in the iPhone interface and it works there without this issue. As I mentioned above, I can easily reproduce this with a new project. Here are the steps if you want to try it out yourself: start new project - split view create new UITableViewController class (i named TableViewController) uncomment out the viewDidLoad method as well as the rightBarButtonItem line in viewDidLoad (so we will have an Edit button in the navigation bar) enter any values you want to return from numberOfSectioinsInTableView and numberOfRowsInSection methods open MainWindow.xib and do the following: please note that you will need to be viewing the xib in the middle "view mode" so you can expand the contents of the items drag a Tab Bar Controller into the xib to replace the Navigation Controller item drag a Navigation Controller into the xib as another item under the Tab Bar Controller delete the other two view controllers that are under the Tab Bar Controller (so, now our tab bar has just the one navigation controller on it) inside the navigation controller, drag in a Table View Controller and use it to replace the View Controller (Root View Controller) change the class of the new Table View Controller to the class created above (TableViewController for me) double-click on the Table View under the new Table View Controller to open it up (will be displayed in the tab bar inside the split view controller) drag a "Search Bar and Search Display" onto the table view save the xib run the project in simulator while in portrait mode, click on the Root List button to bring up popover notice the Edit button is clickable click in the Search box - we go into search mode click the Cancel button to exit search mode notice the Edit button no longer works So, can anyone help me figure out why this is happening? Thanks, Mark

  • Media Foundation: Custom Media Source features

    - by Ivan Dyachkoff
    With IMFMediaSource and IMFByteStreamHandler I can access bytes from media source to determine media type and audio/video stream parameters, such as duration, quality, number of streams, etc. But can I replace these bytes and send them back to client? E.g. I receive zip file bytestream, extract actual media and send another bytestream with asf (for example) data. Is this possible?

  • Linux's thread local storage implementation

    - by anon
    __thread Foo foo; How is "foo" actually resolved? Does the compiler silently replace every instance of "foo" with a function call? Is "foo" stored somewhere relative to the bottom of the stack, and the compiler stores this as "hey, for each thread, have this space near the bottom of the stack, and foo is stored as 'offset x from bottom of stack'"?

    Does anyone know of a script that can select all text references to URLs and automatically replace them with anchor tags pointing to those locations? For example: http://www.google.com would automatically turn into <a href="http://www.google.com">http://www.google.com</a> Note: I am wanting this because I don't want to go through all my content and wrap them with anchor tags.
