• How could I insert a string into the response stream anywhere I want?

  - by DM

  There may be an easy way to do this but I can't see it... I created a simple Http Module that starts a timer on the PreRequestHandler and stops the timer on the PostRequestHandler to calculate the time it took the page to load. I then create some simple html and write my results to Response.Write. Since I'm doing this in the PostRequestHandler it's adding my results after the </html> tag. That's fine for testing but I need in a scenario where the page needs to validate. I can't seem to figure out how I could manipulate the Response object to insert my results before the </body> tag. Response.Write and Response.Output.Write don't have that flexibility and I couldn't see a way to work with the Response as a string. Am I missing something easy?

• Find and list all functions/methods in a set of JavaScript files

  - by Dan Milstein

  Is there a way to read a set of JavaScript files, and output a description of where every function/method is defined? I realize that this is likely impossible in full generality, due to the extreme dynamic nature of the language. What I'm imagining is something which gets the (relatively) straightforward cases. Ideally, I'd want it figure out where, e.g. some method got attached to string or hash or some other fundamental class (and also just let you find all the classes/functions that get defined once in one place). Does such a tool exist?

• ByteArrayOutputStream to PrintWriter (Java Servlet)

  - by Thomas

  Writing generated PDF (ByteArrayOutputStream) in a Servlet to PrintWriter. I am desperately looking for a way to write a generated PDF file to the response PrintWriter. Since a Filter up the hierarchy chain has already called response.getWriter() I can't get response.getOutputStream(). I do have a ByteArrayOutputStream where I generated the PDF into. Now all I need is a way to output the content of this ByteArrayOutputStream to the PrintWriter. If anyone could give me a helping hand would be very much appreciated!

• Include multiple jars with classpathentry

  - by ripper234

  I have an eclipse's .classpath file that looks like this: <?xml version="1.0" encoding="UTF-8"?> <classpath> <classpathentry kind="src" path="src"/> <classpathentry kind="src" path="test"/> <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/> <classpathentry kind="output" path="bin"/> <classpathentry kind="lib" path="/libraries/jee/servlet-api.jar"/> <classpathentry kind="lib" path="/libraries/junit/junit-4.6.jar"/> <classpathentry kind="lib" path="/libraries/log4j/log4j-1.2.15.jar"/> </classpath> I'd like to add a whole directory of jars to the classpath - I like eclipse (or more precisely, our ant-based build process that uses .classpath format) to know several jars that reside in a single directory, without specifying them directly. How can I do that?

• Algorithm of JavaScript "sort()" Function

  - by Knowledge Craving

  Recently when I was working with JavaScript "sort()" function, I found in one of the tutorials that this function does not sort the numbers properly. Instead to sort numbers, a function must be added that compares numbers, like the following code:- <script type="text/javascript"> function sortNumber(a,b) { return a - b; } var n = ["10", "5", "40", "25", "100", "1"]; document.write(n.sort(sortNumber)); </script> The output then comes as:- 1,5,10,25,40,100 Now what I didn't understand is that why is this occurring & can anybody please tell in details as to what type of algorithm is being used in this "sort()" function? This is because for any other language, I didn't find this problem where the function didn't sort the numbers correctly. Any help is greatly appreciated.

• JBoss 4.0.5 startup takes 15 minutes deploying a single war file

  - by dkblinux98

  This instance of JBoss deploys several war files. The rest of the JBoss startup takes about 5 minutes or less. But when it gets to one particular war file, startup just hangs with no further output to the jboss log. It waits there for about 15 minutes and then suddenly the war starts deploying. The rest of the JBoss startup is then fine. What I want to know is what steps do you recommend I take to diagnose the cause of this condition? It is not possible to upgrade this site to a newer version of JBoss nor java (currently 1.5.0.7). It is running on 32-bit CentOS 5.3 Linux on 3 xen-based virtual servers in a load balanced configuration. The code is common to all three servers via an nfs share. This same issue was seen, however, when the 3 servers were physical and the code was local to each server. The servers are each 2 cpu, 4GB RAM servers.

• Not sure how to use Decode, NVL, and/or isNull (or something else?) in this situation

  - by RSW

  I have a table of orders for particular products, and a table of products that are on sale. (It's not ideal database structure, but that's out of my control.) What I want to do is outer join the order table to the sale table via product number, but I don't want to include any particular data from the sale table, I just want a Y if the join exists or N if it doesn't in the output. Can anyone explain how I can do this in SQL? Thanks in advance!

• How can I (reasonably) precisely perform an action every N milliseconds?

  - by Jon Cage

  I have a machine which uses an NTP client to sync up to internet time so it's system clock should be fairly accurate. I've got an application which I'm developing which logs data in real time, processes it and then passes it on. What I'd like to do now is output that data every N milliseconds aligned with the system clock. So for example if I wanted to do 20ms intervals, my oututs ought to be something like this: 13:15:05:0000 13:15:05:0020 13:15:05:0040 13:15:05:0060 I've seen suggestions for using the stopwatch class, but that only measures time spans as opposed to looking for specific time stamps. The code to do this is running in it's own thread, so should be a problem if I need to do some relatively blocking calls. Any suggestions on how to achieve this to a reasonable (close to or better than 1ms precision would be nice) would be very gratefully received.

• Noob Python Question: List Confusion

  - by potatocubed

  I'm trying to transfer the contents of one list to another, but it's not working and I don't know why not. My code looks like this: list1 = [1, 2, 3, 4, 5, 6] list2 = [] for item in list1: list2.append(item) list1.remove(item) But if I run it my output looks like this: >>> list1 [2, 4, 6] >>> list2 [1, 3, 5] My question is threefold, I guess: Why is this happening, how do I make it work, and am I overlooking an incredibly simple solution like a 'move' statement or something?

• Using PHP to grab the absolute URL of the script?

  - by Rob

  Basically, I want my script to output its absolute URL, but I don't want to statically program it into the script. For example, if my current URL is http://example.com/script.php I want to be able to store it as a variable, or echo it. i.e. $url = http://example.com/script.php; But if I move the script to a different server/domain, I want it to automatically adjust to that, i.e. $url = http://example2.com/newscript.php; But I have no idea how to go about doing this. Any ideas?

• Program quits if pipe is closed

  - by givemelight

  I am trying to write to a pipe using C++. The following code gets called in an extra thread: void writeToPipe() { int outfifo; char buf[100]; char outfile[] = "out"; mknod(outfile, S_IFIFO | 0666, 0); if ((outfifo = open(outfile, O_WRONLY)) < 0) { perror("Opening output fifo failed"); return false; } int currentTimestamp = (int)time(0); int bufLen = sprintf(bug, "Time is %d.", currentTimestamp); write(outfifo, buf, bufLen); } The thread is called in main using: thread writeThread(writeToPipe); writeThread.detach(); If the pipe is not opened by another process, the C++ program just quits without an error. I don't know how to check if the pipe is opened.

• InvalidCastException: System.Web.UI.PartialCachingControl -> MyCustomControl when OutputCaching

  - by marcinn

  The problem: I am unable to use OutputCaching with my controls which derives from MyCustomControl. Controls are loaded dynamically using definitions from database with Page.LoadControl method. When I add to ascx <%@ OutputCache VaryByParam="*" Duration="3600"% the "InvalidCastException: System.Web.UI.PartialCachingControl - MyCustomControl" exception is thrown. I am unable to modify assembly witch contains dynamic loading controls logic. Is there any way to fix it in derived controls? The second question is about iis7 and native output caching - is it resolves this problem? (I tried to set up several performance counters and I saw that cache wasn't hit...)

  - by xyz

  Suppose I have a table (tblEmp) whose structure is like as under Dept Emp d1 e1 d1 e2 d1 e3 d2 e4 d2 e5 d3 e6 If I need to bring the output as Dept DepartmentSpecificEmployees d1 e1,e2,e3 d2 e4,e5 d3 e6 I will write the query as select Dept, stuff((select Emp + ',' from tblEmp t2 where t1.Dept = t2.Dept for xml path(''),1,1,'')DepartmentSpecificEmployees from tblEmp t1 group by Dept But this will work in Sql Server 2005+. How can I achieve the same in Sql Server 2000 without any variable declaration or loop or cursor? If I use COALESCE as an alternative, then I need to use a variable which will defeat the purpose Please help

• Limited recursion in C?

  - by function

  I ran this program and it output ... 65088 65089 65090 and then it stopped. Windows 7 said a.exe stopped working. Here is the code: #include <stdio.h> void go(void); main() { go(); } void go(void) { static int i = 0; printf("%d\n", i++); go(); } I think this program should keep on printing numbers indefinitely due to recursion, but it stops at 65090! The C code is compiled with gcc. Any ideas?

• Rails: saving a string on an object -- syntax problem?

  - by Veep

  Hey there, I am trying to write a simple function to clean a filename string and update the object. When I save a test string it works, but when I try to save the string variable I've created, nothing happens. But when I return the string, the output seems to be correct! What am I missing? def clean_filename clean_name = filename clean_name.gsub! /^.*(\\|\/)/, '' clean_name.gsub! /[^A-Za-z0-9\.\-]/, '_' clean_name.gsub!(/\_+/, ' ') #update_attribute(:filename, "test") #<-- correctly sets filename to test #update_attribute(:filename, clean_name) #<-- no effect????? WTF #return clean_name <-- seems to returns the correct string end Thank you very much.

• Parsing timestamps - do it in MySQL or in PHP?

  - by Andrew Heath

  Let's say you've got a table with a timestamp column, and you want to parse that column into two arrays - $date and $time. Do you, personally: a) query like this DATE(timestamp), TIME(timestamp) , or perhaps even going as far as HOUR(timestamp), MINUTE(timestamp b) grab the timestamp column and parse it out as needed with a loop in PHP I feel like (a) is easier... but I know that I don't know anything. And it feels a little naughty to make my query hit the same column 2 or 3 times for output... Is there a best-practice for this?

• Can a parser tell the lexer to ignore a newline?

  - by chollida

  I'm writing a preprocessor for my language. In the preprocessor I've output a line that wasn't in the source file. This causes any error messages that Anltr creates to be incremented by one line. The Lexer handles the line count so I'm wondering if there is a way for the parser to tell the lexer to decrement the line count, or to ignore a specific newline. I'm also open to other suggestions on how to work around this. The only constraint I have is putting the extra line inline with the existing code. I'd prefer to keep it on it's own line to keep my parsing sane.

• Obtaining frame pointer in C

  - by assketchum

  I'm trying to get the FP in my C program, I tried two different ways, but they both differ from what I get when I run GDB. The first way I tried, I made a protocol function in C for the Assembly function: int* getEbp(); and my code looks like this: int* ebp = getEbp(); printf("ebp: %08x\n", ebp); // value i get here is 0xbfe2db58 while( esp <= ebp ) esp -= 4; printf( "ebp: %08x, esp" ); //value i get here is 0xbfe2daec My assembly code getEbp: movl %ebp, %eax ret I tried making the prototype function to just return an int, but that also doesn't match up with my GDB output. We are using x86 assembly. EDIT: typos, and my getEsp function looks exactly like the other one: getEsp: movl %esp, %eax ret

• Does '[ab]+' equal '(a|b)+' in python re module?

  - by user1477871

  I think pat1 = '[ab]' and pat2 = 'a|b' have the same function in Python(python2.7, windows) 're' module as a regular expression pattern. But I am confused with '[ab]+' and '(a|b)+', do they have the same function, if not plz explain details.

• javascript - Google Chrome cluttering Array generated from .split()

  - by patrick

  Given the following string: var str = "one,two,three"; If I split the string on the commas, I normally get an array, as expected: var arr = str.split(/\s*,\s*/); Trouble is that in Google Chrome (for Mac), it appends extra properties to the array. Output from Chrome's debugger: arr: Array 0: one 1: two 2: three constructor: function Array() index: undefined input: undefined length: 3 So if I iterate over the array with a for/in loop, it iterates over the new properties. Specifically the input and index properties. Using hasOwnProperty doesn't seem to help. A fix would be to do a for loop based on the length of the Array. Still I'm wondering if anyone has insight into why Chrome behaves this way. Firefox and Safari don't have this issue.
