Hi, I am reading in a text file using FileInputStream that puts the file contents into a byte array. I then convert the byte array into a String using new String(byte). Once I have the string I'm using String.split("\n") to split the file into a String array and then taking that string array and parsing it by doing a String.split(",...
I have created a plain file which does not have execute permission but when I create a Java File object using this file's path/name and then call File.canExecute() I get true as the result, whereas I would expect this method call to return false. Can someone explain what I'm missing here? Solaris: $ touch /tmp/nonexecutable $ ls -l /t...
In my Java application I am renaming files to a file name provided in a String parameter. There is a method boolean OKtoRename(String oldName, String newName) which basically checks whether the newName isn't already taken by some other file, as I wouldn't want to bury existing ones. It now occurred to me that perhaps the newName Stri...

I have found numerous examples on uploading a file to a web server via C++ on Windows. However I am struggling after a lot of searching (and I thought I was good with Google!) to find any examples to help me achieve the same on a Mac.

I have some .csv files which I'm using as part of a test bench. I can open them and read them without any problems unless I've already got the file open in Excel in which case I get an IOException: System.IO.IOException : The process cannot access the file 'TestData.csv' because it is being used by another process. This is a snippe...
I'm building an application for the iPhone/iPod Touch using a UIWebView object. Manifest files seem like an excellent way to do this, and I have gotten our app to load successfully offline in Safari using this technique. My problem is that once I move into my application, I can't get the manifest files to work offline in my UIWebView o...
Hi, I would like to create a text file for export/download, like a *.csv, from an ASP.NET application. I know about Response.TransmitFile, but I want to do this without creating and saving a file physically on the server. Is that possible? Has anyone done something like that? ...
Hi all, I have a TXT file that i need to import via an application, but for some reason i need to open it in wordpad first and then save it before importing it. I'm guessing it has to do with Line Breaks. Cause if i open it in notepad first, there are no line breaks, but if i open it with wordpad the lines are seperated. Does anyone kn...

I am fairly new to C++ and I have seen a bunch of code that has method definitions in the header files and they do not declare the header file as a class. Can someone explain to me why and when you would do something like this. Is this a bad practice? Thanks in advance! ...

As part of the development phase of my iPhone app it would be really useful to load a file from my local machine, i.e. not from the application bundle. Is that possible? The purpose of this is so that I can build a version of our game, and then give it to one of our designers and they can edit a settings file locally on their machine an...

On most UNIX systems passing an open file between processes can be easily done for child/parent processes by fork(); however I need to share a fd "after" the child was already forked. I've found some webpages telling me that sendmsg() may work for arbitary processes; but that seems very OS dependent and complex. The portlisten seems lik...
I would like to implement a socket-like object in user space. There's an important requirement that it should be pollable (i.e. it's state should be queryable via select or poll call). Is there a platform neutral way of implementing such an object? I'm aware that on Linux there's eventfd which kind of suits the needs except that there'...
Hi, We are using a third part library to render 3d. In this library there is a "memory tracker" functionality that keeps track of all memory the library has allocated and freed during execution. This is a nice feature, since it helps by determining e.g. memory leaks. By calling a certain function in this library a log file is generated...
In C, which is the better practice when it comes to freeing memory returned from functions: Provide a "destructor" function that encapsulates the call to free(). Require users to free() the returned pointer themselves. For example, to open and close a file we do: FILE* f = fopen("blah", "w"); fclose(f); Is this preferable to: FIL...
