• Reallocating memory via "new" in C++

  - by BSchlinker

  Quick question regarding memory management in C++ If I do the following operation: pointer = new char [strlen(someinput_input)+1]; And then perform it again, with perhaps a different result being returned from strlen(someinput_input). Does this result in memory being left allocated from the previous "new" statement? IE, is each new statement receiving another block of HEAP memory from the OS, or is it simply reallocating? Assuming I do a final delete pointer[]; will that deallocate any and all memory that I ever allocated via new to that pointer? Thanks

• Add progressbar to BZip2CompressorInputStream

  - by bordeux

  This is my code: public void extract(String input_f, String output_f){ int buffersize = 1024; FileInputStream in; try { in = new FileInputStream(input_f); FileOutputStream out = new FileOutputStream(output_f); BZip2CompressorInputStream bzIn = new BZip2CompressorInputStream(in); final byte[] buffer = new byte[buffersize]; int n = 0; while (-1 != (n = bzIn.read(buffer))) { out.write(buffer, 0, n); } out.close(); bzIn.close(); } catch (Exception e) { throw new Error(e.getMessage()); } } How can i add progress bar to extract task, or how can i get the compressed file size?

• When are referenced Assemblies loaded?

  - by Daniel

  I wrote a program that makes a reference to Microsoft.Web.Administration.dll, which is not present on Windows Server 2003. The program checks for the os and does not reference the dll if the os is 2003. if(OSVersion == WindowsServer2003) //do the job without referencing the Microsoft.Web.Administration.<br> else if(OSVersion == WindowsServer2008) //reference the Microsoft.Web.Administration.dll file.<br> When I tested this program on Windows Server 2003, an error occured telling me it couldn't locate the Microsoft.Web.Administration.dll. But when I separated the if-else block into 2 different methods as below, and the error did not occur. if(OSVersion == WindowsServer2003) //do the job without referencing the Microsoft.Web.Administration.<br> else if(OSVersion == WindowsServer2008) //DoIt2008Style(); So I wanted to know about reference file loading time in more detail. could you point me to some resources?

• Is there a way to set up a Linux pipe to non-buffering or line-buffering?

  - by ern0

  My program is controlling an external application on Linux, passing in input commands via a pipe to the external applications stdin, and reading output result via a pipe from the external applications stdout. The problem is that writes to pipes are buffered by block, and not by line, and therefore delays occur before my app receives data output by the external application. The external application cannot be altered to add explicit fflush() calls. When I set the external application to /bin/cat -n (it echoes back the input, with line numbers added), it works correctly, it seems, cat flushes after each line. The only way to force the external application to flush, is sending exit command to it; as it receives the command, it flushes, and all the answers appears on the stdout, just before exiting. I'm pretty sure, that Unix pipes are appropiate solution for that kind of interprocess communication (pseudo server-client), but maybe I'm wrong. (I've just copied some text from a similar question: Force another program's standard output to be unbuffered using Python)

• Has ordinal index of functions in Windows API dlls ever changed?

  - by Panda

  You know that functions in a dll can be imported either by name or by ordinal index. From wikipedia: For most Windows API functions only the names are preserved across different Windows releases; the ordinals are subject to change. Thus, one cannot reliably import Windows API functions by their ordinals. My Question: I know these ordinals MAY CHANGE, but I want to know if they've ever ACTUALLY CHANGED. (Especially about kernel32 & user32 dlls) Why I'm asking this? I heard some viruses do import win32 functions by ordinal. I want to catch them, and I want to know whether I can test for an ordinal number or not. Thanks.

  I am calling blackberry map by converting the real coordinates as you can see public static void showMap(String latitude,String longatude){ try{ int specailLatitude=(int)(Double.parseDouble(latitude))*100000; int specailLongatude=(int)(Double.parseDouble(longatude))*100000; MapView mapView=new MapView(); mapView.setLatitude(specailLatitude); mapView.setLongitude(specailLongatude); mapView.setZoom(07); MapsArguments arg=new MapsArguments(mapView); Invoke.invokeApplication(Invoke.APP_TYPE_MAPS, arg); }catch(Exception e){ CustomUtility.showToast("Map is not available "+e.getMessage()); } }// end of the showMap but problem is this its now showing correct location , it always shows same location in UAE , please help that i am converting correctly ?

• What is the benefit to wrapping every sql/stored proc invocation in a transaction?

  - by MatthewMartin

  The following code executes one stored procedure. The stored procedure has only one command in it. Is there any benefit to wrapping everything in a transaction, even it only has one SQL statement in it (or one stored proc that has only one sql statement)? In the sample code below, if the delete fails, it fails. There is nothing else to be rolled back (it seems). So why is everything wrapped in a transaction anyhow? using (ITransactionManager transMan = repository.TransactionManager()) using (IController controller = repository.Controller()) { transMan.BeginTransaction(); try { //DELETE FROM myTable where Id=@id controller.Delete(id); transMan.CommitTransaction(); } catch { transMan.RollbackTransaction(); throw; } }

• The Java interface doesn't declare any exception. How to manage checked exception of the implementat

  - by Frór

  Let's say I have the following Java interface that I may not modify: public interface MyInterface { public void doSomething(); } And now the class implementing it is like this: class MyImplementation implements MyInterface { public void doSomething() { try { // read file } catch (IOException e) { // what to do? } } } I can't recover from not reading the file. A subclass of RuntimeException can clearly help me, but I'm not sure if it's the right thing to do: the problem is that that exception would then not be documented in the class and a user of the class would possibly get that exception an know nothing about solving this. What can I do?

• catching an event in VBScript

  - by be here now

  Hi, guys. This is a VBS script that opens google, fills a form, and clicks a search button. set ie = CreateObject("InternetExplorer.Application") ie.navigate("www.google.com") ie.visible = true while ie.readystate <> 4 wscript.sleep 100 WEnd set fields = ie.document.getelementsbyname("q") set buttons = ie.document.getelementsbyname("btnG") fields(0).value = "some query" buttons(0).click ie.quit Sub OnClickSub() MsgBox "button clicked!", 0 End Sub Obviously, buttons(0).click fires an onclick event of the button, which I somehow need to catch in my script, and provide it with some processing like launching OnClickSub(). Has anyone got any ideas how this should be done?

• Is there a best coding style for indentations (same line, next line)?

  - by Luis Soeiro

  I prefer Pascal-like coding style, where the beginning and ending of a code block are on the same column. I think that it is easier to read and to handle cut and paste than the other kind of coding style. The style I prefer (Pascal-like): void fooBar(String s) { int a; int length=s.length(); for (int i=0;i<length;i++) { if (i>10) { System.out.println(i); System.out.println(s.charAt(i)); } } } The style that was adopted by the Java community: void fooBar(String s) { int a; int length=s.length(); for (int i=0;i<length;i++){ if (i>10){ System.out.println(i); System.out.println(s.charAt(i)); } } } So why do you use one type or the other (please cite an objective reason)?

• Get products to display on custom Magento page

  - by Eric

  How can you get products to display on a custom Magento page? Naturally, this is not an uncommon question but nothing that I've seen has solved it for me. The common response is to put the following code in through the CMS editor: {{block type="catalog/product_list" name="home.catalog.product.list" alias="products_homepage” template=”catalog/product/list.phtml”}} Which just displays the message "There are no products matching the selection." on my page. Other websites advise reindexing the data through the Magento admin controls, clearing the Magento cache, and making sure products are set to a store, none of which helped in my case. Anyone have any ideas?

• jQuery code to track clicks on outgoing links (google analystics)

  - by Tristan

  Hello, I found this on the web: $('a[href^=http]:not("[href*=://' + document.domain + ']")').click(function() { pageTracker._trackPageview('/outgoing/' + $(this).attr('href')); }); But it's not working. In my Google Analytics account there are no /outgoing/ links showing (it's been 24+ hours since I implemented it). What's wrong with this code? I'm using jQuery of course ;) (PS : i already have : <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E")); </script> <script type="text/javascript"> try { var pageTracker = _gat._getTracker("UA MY CODE"); pageTracker._trackPageview(); } catch(err) {}</script>)

• BASH: Checking for environment variables

  - by Hamza

  Hi folks, I am trying to check the value of an environment variable and depending on the value do certain things and it works fine as long as the variable is set. When it isn't though I get a whole bunch of errors (as BASH is trying to compare the string I specify with an undefined variable, I guess) I tried implementing an extra check to prevent it happening but no luck. The block of code I am using is: #!/bin/bash if [ -n $TESTVAR ] then if [ $TESTVAR == "x" ] then echo "foo" exit elif [ $TESTVAR == "y" ] then echo "bar" exit else echo "baz" exit fi else echo -e "TESTVAR not set\n" fi And this the output: $ export TESTVAR=x $ ./testenv.sh foo $ export TESTVAR=y $ ./testenv.sh bar $ export TESTVAR=q $ ./testenv.sh baz $ unset TESTVAR $ ./testenv.sh ./testenv.sh: line 5: [: ==: unary operator expected ./testenv.sh: line 9: [: ==: unary operator expected baz My question is, shouldn't 'unset TESTVAR' nullify it? It doesn't seem to be the case... Thanks.

• How to find foreign-key dependencies pointing to one record in Oracle?

  - by daveslab

  Hi folks, I have a very large Oracle database, with many many tables and millions of rows. I need to delete one of them, but want to make sure that dropping it will not break any other dependent rows that point to it as a foreign key record. Is there a way to get a list of all the other records, or at least table schemas, that point to this row? I know that I could just try to delete it myself, and catch the exception, but I won't be running the script myself and need it to run clean the first time through. I have the tools SQL Developer from Oracle, and PL/SQL Developer from AllRoundAutomations at my disposal. Thanks in advance!

• jQuery doesn't fire some events while I'm not logged in (Joomla)

The site is still in developement, so no live version sadly. UPDATE: jQuery(window).resize(function() { var windowSize = jQuery(window).width() var windowWidth = (jQuery(window).width()-60)/6; var windowHeight = windowWidth/1.6; /*grid resize*/ jQuery('.xc-block').css({'width':windowWidth, 'height':windowHeight}); }); This is very simple script, cant really tell what can be wrong... Any thoughts guys? P.S:also no errors in FireBug...

• What is a good practice for handling SQL connections within a WCF call?

  - by Rising Star

  Suppose I want to create a (stateless) WCF service with three methods exposed on an endpoint: performSqlOperationA(), performSqlOperationB(), and performSqlOperationC(). Each method inserts data into a SQL database. The way I've seen things done at my office, each method would begin with code to initialize a SqlConnection object. Each method would end with code to safely dispose it. What is a good practice for coding these WCF methods so that the SqlConnection object is initialized and disposed in each method without having to do these things in each method? I know that I can have the connection initialized in the constructor for the class for the WCF methods, but I don't know about disposing it... The calls cannot be wrapped in a using block. One solution I'm familiar with is PostSharp, which allows me to set an attribute which causes specific code to automatically run at the beginning and end of each method call, but it would be greatly preferable to do this with only the .net framework.
