• Modular HTML in Adobe AIR? Is It Possible?

  - by Greg Bulmash

  When I write HTML with a PHP backend, I usually have a single header file and a single footer file with some PHP variables in them. The base skeleton for every page calls the header, contains the body content, and then calls the footer. That way, if I want to make changes to the header sitewide, I change one file. I'm working on developing the UI in my first Adobe AIR app and I'm wondering if there's some way to include such files in an HTML based page template there. Obviously, with the file read/write abilities in AIR, I can write a Javascript routine to pull data from a header file, parse it, and inject it into a placeholder. It just seems like such a kludge. I'm thinking there's gotta be some simple way to import a block of HTML into a page without an iFrame or complex post-processor. Something like a PHP include statement or perhaps the old Server Side Includes. Any methods you guys can recommend?

• Run batch file when argument contains quotes and spaces (from .NET framework)

  - by turtle

  I have a bat file which sets some environment variables, and then executes a command on the command line. I want to replace the hard coded command with one passed in via a parameter. So: :: Set up the required environment SET some_var=a SET another_var=b CALL some.bat :: Now call the command passed into this batch file %1 The problem is that the command is complex, and doesn't escape cleanly. It looks like this: an.exe -p="path with spaces" -t="some text" -f="another path with spaces" I'm trying to call the .bat from a .NET framework app, using: Dim cmd as String = "the cmd" System.Diagnostics.Process.Start( thebat.exe, cmd ) but I can't seem to get the escapes to work correctly. Can someone tell me how the string cmd should be entetered to get the command passed into the bat file as an argument correctly?

• [PHP] - Lowering script memory usage in a "big" file creation

  - by Riccardo

  Hi there people, it looks like I'm facing a typical memory outage problem when using a PHP script. The script, originally developed by another person, serves as an XML sitemap creator, and on large websites uses quite a lot of memory. I thought that the problem was related due to an algorithm holding data in memory until the job was done, but digging into the code I have discovered that the script works in this way: open file in output (will contain XML sitemap entries) in the loop: ---- for each entry to be added in sitemap, do fwrite close file end Although there are no huge arrays or variables being kept in memory, this technique uses a lot of memory. I thought that maybe PHP was buffering under the hood the fwrites and "flushing" data at the end of the script, so I have modified the code to close and open the file every Nth record, but the memory usage is still the same.... I'm debugging the script on my computer and watching memory usage: while script execution runs, memory allocation grows. Is there a particular technique to instruct PHP to free unsed memory, to force flushing buffers if any? Thanks

• Is a function kind of like a static method?

  - by lkm

  I'm a java programmer and am trying to understand the difference between a method (java methods) and a function (such as in c++). I used to think that they are the same, just different naming conventions for different programming languages. But now that I know they are not, I am having trouble understanding the difference. I know that a method relates to an instance of a class and has access to class data (member variables), while a function does not (?). So is a function kind of like a static method? See here for explanations I read which led me to think this.

• POSIX Threads and signal masks

  - by Max

  Is there a way to change the signal mask of a thread from another thread? I am supposed to write a multithreaded C application that doesn't use mutex, semaphores and condition variables, only signals. So it would look like something like this: The main Thread sends SIGUSR1 to its process and and one of the 2 threads (not including the main thread), will respond to the signal and block SIGUSR1 from the sigmask and sleep. Then the main thread sends SIGUSR1 again, the other thread will respond, block SIGUSR1 from its sigmask, unblock SIGUSR1 from the other threads sigmask, so it will respond to SIGUSR1 again. So essentially whenever the main thread sends SIGUSR1 the two other threads swap between each other. Can somebody help?

• parsing primitive types using java.util.Scanner

  - by Rich Fluckiger

  I'm new to java so forgive the noob question. I have created a swing application that basically has three input strings in JTextFields: loanAmount, interestRate and loanYears and a single submit button with the EventAction. I'm trying to use the java.util.Scanner to parse the input to primitive types that I can use in calculations. I'm getting an error in NetBeans indicating that my variables are not recognized? should I not be calling System.in? private void submitButtonActionPerformed(java.awt.event.ActionEvent evt) { Scanner keyInput = new Scanner(System.in); while (true) try{ double amount = keyInput.nextDouble(loanAmount.getText()); double interest = keyInput.nextDouble(interestRate.getText()); int years = keyInput.nextInt(loanYears.getText()); } catch (NumberFormatException nfe){ } }

• Login Functionality For Silverlight Application

  - by peter

  Hi All, I have a silverlight application that requires the user to login. The problem is when you hit the refresh button on the web page it reloads the site, and requires the user to login again. What I want it to do is act like ASP .NET where the user will remain logged in for 20 minutes even if they hit the refresh button. What mechanism is ASP .NET using to achieve this? Does it use session variables for instance, and how does it expire after 20 minutes? Thanks.

• Are raw C++ pointers first class objects?

  - by Shailesh Kumar

  According to Wikipedia: An object is first-class when it: can be stored in variables and data structures can be passed as a parameter to a subroutine can be returned as the result of a subroutine can be constructed at runtime has intrinsic identity (independent of any given name) Somebody had once told me that raw pointers are not first class objects while smart pointers like std::auto_ptr are. But to me, a raw pointer (to an object or to a function) in C++ does seem to me to satisfy the conditions stated above to qualify as a first class object. Am I missing something?

• How to input test data using the DecisionTree module in python?

  - by lifera1n

  On the Python DescisionTree module homepage (DecisionTree-1.6.1), they give a piece of example code. Here it is: dt = DecisionTree( training_datafile = "training.dat", debug1 = 1 ) dt.get_training_data() dt.show_training_data() root_node = dt.construct_decision_tree_classifier() root_node.display_decision_tree(" ") test_sample = ['exercising=>never', 'smoking=>heavy', 'fatIntake=>heavy', 'videoAddiction=>heavy'] classification = dt.classify(root_node, test_sample) print "Classification: ", classification My question is: How can I specify sample data (test_sample here) from variables? On the project homepage, it says: "You classify new data by first constructing a new data vector:" I have searched around but have been unable to find out what a data vector is or the answer to my question. Any help would be appreciated!

• Anonymous code blocks in Groovy

  - by piepera

  Is there a way to use anonymous code blocks in Groovy? For example, I'm trying to translate the following Java code into Groovy: { int i = 0; System.out.println(i); } int i = 10; System.out.println(i); The closest translation I can come up with is the following: boolean groovyIsLame = true; if (groovyIsLame) { int i = 0; System.out.println(i); } int i = 10; System.out.println(i); I know anonymous code blocks are often kind of an antipattern. But having variables with names like "inputStream0" and "inputStream1" is an antipattern too, so for this code I'm working on, anonymous code blocks would be helpful.

• Console App Mouse-Click X Y Coordinate Detection/Comparison

  - by Bloodyaugust

  I have a game that I am working on in a C# console application, purely as practice before going on to better methods. As opposed to using something such as a Windows Forms App, which has button functionality built in, I am endeavoring to grab the cursor position (which I know how to do) and compare it to a number of area's inside a console application as defined by perhaps pixel location, but I also do not know if there is some sort of built in unit of space other than pixels (this last bit is the part I am unable to figure). P.S. I know this is in general terms, with no code already provided, but I do not feel that it is needed as all I am asking for is a brief explanation of how to grab X Y coordinates inside a console application, and stick them in int variables. Many Thanks in advance! :D

• Fetching JSON object from Servlet Java

  - by ChrisA

  I want to create an application that will fetch a JSON object from a servlet to deserialize it, and then use its variables to do other things. My servlet has the following code in the doPost: protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ObjectOutputStream os; os = new ObjectOutputStream(response.getOutputStream()); String s = new String("A String"); Gson gson = new Gson(); String gsonObject= gson.toJson(s); os.writeObject(gsonObject); os.close(); } Now, while the servlet is running, I can access it via a browser, if I post same code in the doGet method, that would download a servlet file, which is not what I want. What should I use in my second application that would connect to the servlet, fetch the object, so that I can manipulate it later? Thanks in advance.

• Generate accessors in Visual C++ 2008

  - by gramm

  Hi, I'm trying to generate the accessors and mutators for my variables automatically, but just can't find a way. I tried the right-click/refactor... solution, but the refactor item doesn't appear. I'm not in the mood right now to learn how to write a macro to do this, and I don't have the money to buy a commercial solution (internship student). Any help is welcome, I don't feel like writing all my get/set by hand. note : it's C++ so the {get;set} syntax doesn't work (or does it ?).

• The best way to deploy one site for two companies in ColdFusion?

  - by Ofeargall

  My client has multiple companies; different names/logos etc, but all the content on the sites are identical with the exception of said names/logos. In a ColdFusion environment, what would be the best way for me to serve up identical content and swap out the logos/company names on the fly so I can keep everything in one spot? Is this a jQuery solution? regex? Or will ColdFusion enable me to deploy this in an efficient manner based on the url and session variables?

• Android use of an string array on another method

  - by spagi

  Hi all. Im trying to make an activity that has a multiple choice dialog after you push a button. In there you select from a list of things. But these things are received from a web method before the dialog appears. So I create a string array after I receive them inside the onCreate to initialise it there with the correct size. But my dialog method then cant get the array because propably its out of its scope. My code looks like this @Override protected Dialog onCreateDialog(int id) //Here is where the array is loaded to the multiple select dialog etc @Override public void onCreate(Bundle savedInstanceState) //Here is where i initialise the array and get its contents etc I cant initialise my array when the class starts because I dont know its size yet. This has to do something with the scopes of my variables and I am pretty confused

• [SOLVED]Port C's fread(&struct,....) to Python

  - by user287669

  Hey, I'm really struggling with this one. I'am trying to port a small piece of someone else's code to Python and this is what I have: typedef struct { uint8_t Y[LUMA_HEIGHT][LUMA_WIDTH]; uint8_t Cb[CHROMA_HEIGHT][CHROMA_WIDTH]; uint8_t Cr[CHROMA_HEIGHT][CHROMA_WIDTH]; } __attribute__((__packed__)) frame_t; frame_t frame; while (! feof(stdin)) { fread(&frame, 1, sizeof(frame), stdin); // DO SOME STUFF } Later I need to access the data like so: frame.Y[x][y] So I made a Class 'frame' in Python and inserted the corresponding variables(frame.Y, frame.Cb, frame.Cr). I have tried to sequentially map the data from Y[0][0] to Cr[MAX][MAX], even printed out the C struct in action but didn't manage to wrap my head around the method used to put the data in there. I've been struggling overnight with this and have to get back to the army tonight, so any immediate help is very welcome and appreciated. Thanks

• FastCGI C++ program and missing SCRIPT_NAME

  - by Simone Margaritelli

  Hi guys, i'm studying the fastcgi developement kit because i'm writing a new scripting language and i'd like to write a fastcgi version of the interpreter to run scripts as webpages. I'm using this example from the sdk, located at /srv/http/bin/echocpp So, in my httpd.conf file, i have the following lines : FastCgiServer /srv/http/bin/echocpp -idle-timeout 120 -processes 4 ScriptAlias / /srv/http/bin/echocpp/ ... ... AddHandler fastcgi-script hy Where 'hy' is the extensions of my scripts. Then, when i try browse, for instance http://localhost/~evilsocket/prime.hy I see all the environment variables as expected from the echo-cpp.cpp programm, except for the SCRIPT_NAME that is empty. Is there something i'm missing out of this? How am i supposed to obtain the full path of the script to run it inside my fastcgi version of the interpreter? Thanks

• Objective-c pointer assignment and reassignment dilema

  - by moshe

  Hi, If I do this: 1 NSMutableArray *near = [[NSMutableArray alloc] init]; 2 NSMutableArray *all = [[NSMutableArray alloc] init]; 3 NSMutableArray *current = near; 4 current = all; What happens to near? At line 3, am I setting current to point to the same address as near so that I now have two variables pointing to the same place in memory, or am I setting current to point to the location of near in memory such that I now have this structure: current - near - NSMutableArray The obvious difference would be the value of near at line 4. If the former is happening, near is untouched and still points to its initial place in memory. If the latter is happening,

• Prevent PHP sesison hijack, are these good ideas?

  - by matthew Rhodes

  I'm doing a simple shopping cart for a small site. I plan to store cart items as well as logged in user_id in session variables. to make things a little more secure, I thought I'd do this: sha1() the user_id before storing it in the session. Also sha1() and store the http_user_agent var with some salt, and check this along with the user_id. I know there is more one can do, but I thought this at least helps quite a bit right? and is easy for me to implement.

• BASH Expression to replace beginning and ending of a string in one operation?

  - by swestrup

  Here's a simple problem that's been bugging me for some time. I often find I have a number of input files in some directory, and I want to construct output file names by replacing beginning and ending portions. For example, given this: source/foo.c source/bar.c source/foo_bar.c I often end up writing BASH expressions like: for f in source/*.c; do a="obj/${f##*/}" b="${a%.*}.obj" process "$f" "$b" done to generate the commands process "source/foo.c" "obj/foo.obj" process "source/bar.c "obj/bar.obj" process "source/foo_bar.c "obj/foo_bar.obj" The above works, but its a lot wordier than I like, and I would prefer to avoid the temporary variables. Ideally there would be some command that could replace the beginning and ends of a string in one shot, so that I could just write something like: for f in source/*.c; do process "$f" "obj/${f##*/%.*}.obj"; done Of course, the above doesn't work. Does anyone know something that will? I'm just trying to save myself some typing here.
