  • MAC OS X: How to determine if filesystem is case sensitive?

    - by trojanfoe
    I have used the statfs(2) system call to get many characteristics of a Mac OS X filesystem, but it doesn't tell me if the filesystem is case-sensitive or not. I need this information as the application I am developing will be moving many files around and I want to detect potential loss of data due to files being moved from a case-sensitive filesystem to a case-insensitive filesystem. Can anyone suggest a way of detecting this?

  • Skipp default parameters in Delphi

    - by Vijay Bobba
    Hi Is there any way to skip the default params, say suppose my method declaration is like this: procedure Myfunc1(var isAttr1: Boolean = FALSE; isAttr2: Boolean = FALSE; isAttr3: Boolean = FALSE); I can't call the function like this: Self.Myfunc1( , , Attr3); because I don't want unnecessary var declarations, at the same time I want the last param return value (it is a var type) Thank for help in advance

  • C++ header files and variable scope

    - by MrDatabase
    I want to organize my c++ variables and functions in the following way: function prototypes in a header file "stuff.h", function implementation in "stuff.cpp", then say #include "stuff.h" in main.cpp (so I can call functions implemented in stuff.cpp). So far so good. Now I want to declare some variables in stuff.cpp that have global scope (so I can modify the variables in functions implemented in stuff.cpp and main.cpp). This doesn't seem to work. How can I do this?

  • resignFirstResponder when tapping UITableView?

    - by Canada Dev
    I have a UITableView with two custom cells and each of them has a subview with a UITextField inside it. I have tried adding a UIButton on top of the UITableView and have it resignFirstResponder but that just means you won't be able to tap anywhere else - not even on the UITextFields to enter text. How do I make it so if I tap outside those two UITextFields, I can call resignFirstResponder, so the user can get back to the other cells? Thanks

  • Deleting document attachments in CouchDb

    - by henrik_lundgren
    In CouchDb's documentation, the described method of deleting document attachments is to send a DELETE call to the attachment's url. However, I have noticed that if you edit the document and remove the attachment stub from the _attachment field, it will not be accessible anymore. If i remove foo.txt from the document below and save to CouchDb it will be gone the next time I access the document: { "_id":"attachment_doc", "_rev":1589456116, "_attachments": { "foo.txt": { "stub":true, "content_type":"text/plain", "length":29 } } } Is the attachment actually deleted on disk or is just the reference to it deleted?

  • SDWebImage : setImageWithURL fails when used to set image of a UITableViewCell

    - by Chim
    When call setImageWithURL, it fails with following, [UIImageView setImageWithURL:placeholderImage:]: unrecognized selector sent to instance 0x149a20 2011-12-14 18:11:38.060 [781:707] Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIImageView setImageWithURL:placeholderImage:]: unrecognized selector sent to instance 0x149a20' I can confirm I have included SDWebImage project and required headers correctly as I can use the SDWebImageManager successfully. Following is the code where I called the UIImageView category method setImageWithURL NSURL* url = [NSURL URLWithString:@"www.abc.com/abc.png"]; [cell.imageView setImageWithURL:url placeholderImage:[UIImage imageNamed:@"abc.png"]];

  • Best way to send floating point numbers from .NET to Java and back

    - by Evgeny
    I'm writing a .NET application that will make an RPC call to a Java application (via a message queue). The data sent in both directions will be large arrays of floating-point numbers. What is the best way to serialize them to send them across the wire? I'd like something more compact than text, but architecture-independent as the server may not be an x86 machine. The Java application can be changed as needed.

  • Question about fwrite API

    - by michael
    Hi, In C++, there is a fwrite() which writes a buffer to a file on disk: http://www.cplusplus.com/reference/clibrary/cstdio/fwrite/ Can you please tell me if there is any buffer inside that fwrite implementation? i.e. if I call fwrite() multiple times (say 10 times), does it actually invoke file i/o 10 different times? Thank you.

  • Accessing Arbitrary Columns from an R Data Frame using with()

    - by johnmyleswhite
    Suppose that I have a data frame with a column whose name is stored in a variable. Accessing this column using the variable is easy using bracket notation: df <- data.frame(A = rep(1, 10), B = rep(2, 10)) column.name <- 'B' df[,column.name] But it is not obvious how to access an arbitrary column using a call to with(). The naive approach with(df, column.name) effectively evaluates column.name in the caller's environment. How can I delay evaluation sufficiently that with() will provide the same results that brackets give?

  • InternetCheckConnection in VB6 returning false

    - by user191582
    Hi all, Not a VB6 expert... Trying to come up with a VB6 test app that calls InternetCheckConnection. In my test app, InternetCheckConnection always returns false regardless of the URL I use. I copied and pasted this code from a larger spaghetti-code app, but in the spaghetti-code, InternetCheckConnection seems to work fine, returns true. Is there some other function I have to call first in order for InternetCheckConnection to work?
