  I am trying to send data to a servlet from a js file but the servlet never received the parameter. so this is what I have: function showProject(prj) { xmlhttp=GetXmlHttpObject(); if (xmlhttp==null) { alert ("Browser does not support HTTP Request"); return; } var url="ServletxmlGenerator"; idprj = prj.options[prj.selectedIndex].value; //alert(idprj); url=url+"?idprj="+idprj; xmlhttp.onreadystatechange=stateChanged; xmlhttp.open("GET",url,true); xmlhttp.send(null); } and to capture th request it is with: public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String projectcode=request.getParameter("idprj"); System.out.println("++++projectCode:=" +projectcode); the output is like: ++++projectCode:=null Can any one explain it to me it seems to be correct but i didnot find the error.Thinks

• C#, WindowsForms difference to simple Console App

  - by daemonfire300

  Hi there, I currently started to "port" my console projects to WinForms, but it seems I am badly failing doing that. I am simply used to a console structure: I got my classes interacting with each other depending on the input coming from the console. A simple flow: Input -> ProcessInput -> Execute -> Output -> wait for input Now I got this big Form1.cs (etc.) and the "Application.Run(Form1);" But I really got no clue how my classes can interact with the form and create a flow like I described above. I mean, I just have these "...._Click(object sender....)" for each "item" inside the form. Now I do not know where to place / start my flow / loop, and how my classes can interact with the form. thanks and regards daemonfire

• PHP urlencode() tacking on ?SID=xxx ... Why?

  - by retailevolved

  I am trying to output a simple link. This works great: $url = 'http://www.google.com'; echo $url; This doesn't work great: $url = 'http://www.google.com'; echo urlencode($url); The second example tacks on "?SID=xxx" to the end of the URL for some reason. How do I prevent this from happening? Note: The code to generate the URL has been changed to protect the innocent.

• Writing from an array to a file bash and new lines

  - by S1syphus

  I'm trying to write a script the generates a template file for Pashua (a perl script for creating GUI on osx) I want to crate an instance for each item in the array, so the ideal output would be: AB1.type = openbrowser AB1.label = Choose a master playlist file AB1.width=310 AB1.tooltip = Blabla filesystem browser AB2.type = openbrowser AB2.label = Choose a master playlist file AB2.width=310 AB2.tooltip = Blabla filesystem browser ...and so on for the rest of the array: What I am using to write to the text file at the moment is: count=1 saveIFS="$IFS" IFS=$'\n' array=($(<TEST.txt)) IFS="$saveIFS" for i in "${array[@]}"; do declare AD$count="$i"; ((count++)); done for i in "${array[@]}"; do echo "AD$count".type = openbrowser "AD$count".label = Choose a master playlist file \n "AD$count".width=310 \n "AD$count".tooltip = Blabla filesystem browser \n" >> long.txt; done However \n doesn't produce a newline in the text file, and I am pretty sure there is a alot nicer way todo this, ideas?

• Different between &$DataRow and $DataRow

  - by KoolKabin

  hi guys, I am confused from the result of the following code: I can't get my expected result: $arrX = array('a'=>array('val'=>10),'b'=>array('val'=>20), 'c'=>array('val'=>30)); foreach( $arrX as &$DataRow ) { $DataRow['val'] = $DataRow['val'] + 20; } foreach( $arrX as $DataRow ) { echo '<br />val: '.$DataRow['val'].'<br/>'; } Output: 30, 40, 40 Expected: 30, 40, 50 But again if i make small chage it works fine, $arrX = array('a'=>array('val'=>10),'b'=>array('val'=>20), 'c'=>array('val'=>30)); foreach( $arrX as &$DataRow ) { $DataRow['val'] = $DataRow['val'] + 20; } foreach( $arrX as &$DataRow ) { echo '<br />val: '.$DataRow['val'].'<br/>'; }

• Eclipse CDT printing selected C code snippets/functions

  - by Sint

  Is there a quick and dirty way to print(to dead trees) selected code (C in this case) snippets? In particular, I wanted to print about 200 lines worth of code, but print dialog only offers printing of particular pages or all pages, but not selected text! Of course, one can copy and paste into another editor, but that seems rather harsh. Also, one can output the whole shebang to .pdf but that again seems a way of doing things wrong. Perhaps there is a better way? System: Ubuntu 10.04, Eclipse 3.5 with CDT, Subversive plugin

• Slider Not Behaving As I Would Expect

  - by Adam Waite

  I have a slider that changes a float from 1 to 10 but I want to save this value and use it across all view controllers so I have saved that float as an NSNumber in a model class (settingsData.sensitivitySliderSettingValue). I am trying to output the updated slider value to the console every time that it is changed however it just gets set to 0 rather than 0 to 10. I don't understand why this is... Here's my code: -(IBAction)sensitivitySliderValueChanged:(id)sender { [self updateSensitivity]; } -(void)updateSensitivity{ settingsData.sensitivitySettingValue = [NSNumber numberWithFloat:sensitivitySlider.value]; NSLog(@"The Slider Value is: %1.1f", [settingsData.sensitivitySettingValue floatValue]); }

• Powershell and some simple string manipulation

  - by Pat

  need some help with building a powershell script to help with some basic string manipulation. I know just enough powershell to get in trouble, but can't figure out the syntax or coding to make this work. I have a text file that looks like this - Here is your list of servers: server1 server2.domain.local server3 Total number of servers: 3 I need to take that text file and drop the first and last lines (Always first and last.) Then I need to take every other line and basically turn it into a CSV file. The final output should be a text file that looks like this - server1,server2.domain.local,server3 Any suggestions on where to start? Thanks!

• UTF-8 xml file shows Gibberish

  - by Adam

  I have a UTF-8 encoded xml file, which was exported from a Wordpress MySQL database. While the file is saved as UTF-8, and the encoding is UTF-8, I get gibberish instead of the Hebrew text that is supposed to be in there, which looks like this: ™×•×˜×•×ª How can I find the original encoding or charset and convert the text into proper Hebrew? PHP's mb_detect_encoding($str); returns UTF-8 Tried all sorts of php encoding functions, with different settings and input/output charsets, but they all just print different looking gibberish blocks, like: ÃâÃËÃâ¢Ãâ¢ÃËà and ?? ××©×ž× ...Any Ideas how to go about this?

• Why Does Piping Binary Text to the Screen often Horck a Terminal

  - by Alan Storm

  Imaginary Situation: You’ve used mysqldump to create a backup of a mysql database. This database has columns that are blobs. That means your “text” dump files contains both strings and binary data (binary data stored as strings?) If you cat this file to the screen $ cat dump.mysql you’ll often get unexpected results. The terminal will start beeping, and then the output finishes scrolling by you’ll often have garbage chacters entered on your terminal as through you’d typed them, and sometimes your prompts and anything you type will be garbage characters. Why does this happen? Put another way, I think I’m looking for an overview of what’s actually happening when you store binary strings into a file, and when you cat those files, and when the results of the cat are reported to the terminal, and any other steps I’m missing.

• Unsigned long with negative value

  - by egiakoum1984

  Please see the simple code below: #include <iostream> #include <stdlib.h> using namespace std; int main(void) { unsigned long currentTrafficTypeValueDec; long input; input=63; currentTrafficTypeValueDec = (unsigned long) 1LL << input; cout << currentTrafficTypeValueDec << endl; printf("%u \n", currentTrafficTypeValueDec); printf("%ld \n", currentTrafficTypeValueDec); return 0; } Why printf() displays the currentTrafficTypeValueDec (unsigned long) with negative value? The output is: 9223372036854775808 0 -9223372036854775808

• Is there a simpler way to convert a byte array to a 2-byte-size hexadecimal string?

  - by Tom Brito

  Is there a simpler way of implement this? Or a implemented method in JDK or other lib? /** * Convert a byte array to 2-byte-size hexadecimal String. */ public static String to2DigitsHex(byte[] bytes) { String hexData = ""; for (int i = 0; i < bytes.length; i++) { int intV = bytes[i] & 0xFF; // positive int String hexV = Integer.toHexString(intV); if (hexV.length() < 2) { hexV = "0" + hexV; } hexData += hexV; } return hexData; } public static void main(String[] args) { System.out.println(to2DigitsHex(new byte[] {8, 10, 12})); } the output is: "08 0A 0C" (without the spaces)

• Good way to format decimal in SQL Server

  - by Brad

  We store a decimal(9,8) in our database. It can have any number of places after the decimal point (well, no more than 8). I am frustrated because I want to display it as human-readable text as part of a larger string created on the server. I want as many decimals to the right of the decimal point as are non-zero, for example: 0.05 0.12345 3.14159265 Are all good If I do CAST(d AS varchar(50)) I get formatting like: 0.05000000 0.12345000 3.14159265 I get similar output if I cast/convert to a float or other type before casting to a varchar. I know how to do a fixed number of decimal places, such as: 0.050 0.123 3.142 But that is not what I want. Yes, I know I can do this through complicated string manipulation (REPLACE, etc), there should be a good way to do it.

• T-SQL: How Do I Create A "Private" Function Inside A Stored Procedure

  - by RPM1984

  Okay so im writing a SQL Server 2008 Stored Procedure (maintenance script). In doing so, being a good boy i've done plenty of error handling, checking rowcounts, printing output messages, etc But in doing this, ive found myself writing over and over again something like this: SELECT @RowsAffected = @@ROWCOUNT IF @RowsAffected > 0 BEGIN PRINT CAST(@RowsAffected, NVARCHAR(2)) + 'rows updated.' END Or debug messages like this: PRINT 'User ' + CAST(@UserId AS NVARCHAR(5)) + ' modified successfully' Is there a way i can create a kind of 'subroutine' inside the stored procedure (like a private method) that can accept something as a parameter (doesnt have to though) and do some logic? I want to be able to do something like this: CheckRowCounts Or this: PrintUserUpatedMessage(@UserId) Which would then perform the above logic (check rowcount, print message, etc) And yes obviously i can create a UDF, but then i would need to create/drop it etc as this logic is only required for the life of the execution of this stored procedure. Getting sick and tired of writing the same code over and over again, and changing all the different areas ive used it when i get an error =) Can anyone help?

• How to override environment variables when running configure?

  - by Sam

  In any major package for Linux, running ./configure --help will output at the end: Some influential environment variables: CC C compiler command CFLAGS C compiler flags LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a nonstandard directory <lib dir> CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have headers in a nonstandard directory <include dir> CPP C preprocessor Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations. How do I use these variables to include a directory? I tried running ./configure --CFLAGS="-I/home/package/custom/" and ./configure CFLAGS="-I/home/package/custom/" however these do not work. Any suggestions?

• Ideal Java library for cleaning html, and escaping malformed fragments

  - by Tyler

  I've got some HTML files that need to be parsed and cleaned, and they occasionally have content with special characters like <, , ", etc. which have not been properly escaped. I have tried running the files through jTidy, but the best I can get it to do is just omit the content it sees as malformed html. Is there a different library that will just escape the malformed fragments instead of omitting them? If not, any recommendations on what library would be easiest to modify? Clarification: Sample input: <p> blah blah <M+1> blah </p> Desired output: <p> blah blah &lt;M+1&gt; blah </p>

• An efficient code to determine if a set is a subset of another set

  - by Edward

  I am looking for an efficient way to determine if a set is a subset of another set in Matlab or Mathematica. Example: Set A = [1 2 3 4] Set B = [4 3] Set C = [3 4 1] Set D = [4 3 2 1] The output should be: Set A Sets B and C belong to set A because A contains all of their elements, therefore, they can be deleted (the order of elements in a set doesn't matter). Set D has the same elements as set A and since set A precedes set D, I would like to simply keep set A and delete set D. So there are two essential rules: 1. Delete a set if it is a subset of another set 2. Delete a set if its elements are the same as those of a preceding set My Matlab code is not very efficient at doing this - it mostly consists of nested loops. Suggestions are very welcome! Additional explanation: the issue is that with a large number of sets there will be a very large number of pairwise comparisons.

• CakePHP - Just Layout?

  - by Kieran

  I want to set $this->layout to json in the controller action. In the json layout, there will be a line saying $this->Javascript>object(); which will parse through the data given to it by the controller, and output the jSON. However, creating a new view file for each jSON request, eg. recipe_view, ingredient_view isn't necessary, I just need a layout. Is there a way to bypass the view file altogether and have just the layout, without the notorious Missing View! error? Many Thanks Kieran

• What happened to the Windows "Midi Mapper"

  - by interstar

  I wrote a windows program many years ago, which created music by sending notes to the "midi mapper" (and thence to the midi-synth on my sound-card) Today, I have a soft-synth which, allegedly accepts midi information, so I'd assume it should be possible to use today's equivalent of a midi-mapper to route the midi output from my program to the soft-synth. There's clearly no longer a midi-mapper application in windows, but my program still works (on XP) in that it drives the built-in soundcard synth, so there must be some sort of midi handling layer in windows. How can I get at this? And maybe redirect the midi to the soft-synth?

• How to do 'git status' on untracked directory?

  - by meowsqueak

  I have 6,000 untracked files in one subdirectory and I'm constructing .gitignore files to filter out the unwanted ones. I'm testing my gitignore filters as I go by running 'git status'. However, I have a larger number of untracked other files in a different subdirectory, so 'git status' shows all of those too, which makes it very hard to see what the .gitignore rules are doing. If the files were tracked, then I could just do 'git status .' and it would restrict the git-status output to only those files in the current directory, but because the current directory and all its contents are untracked, 'git status .' returns "error: pathspec . did not match any file(s) known to git." I'm using git-1.6.6.1 for this, although interestingly my testing shows that git-1.7.1 (on a different system) does actually let you do git-status on an untracked directory. Unfortunately I can't upgrade git on this system. Is there a known workaround for -1.6.6.1?
