• Mail merge from Java

  - by Mike Q

  Hi all, Does anyone have any experience with doing mail merge from Java on a word document? I need to support both doc and docx formats. I have heard of Apache POI and docx4j. However, from reading around I'm sure how good the word support is in POI. docx4j only supports docx format as far as I can see. Can any suggest either one of the above (and correct my knowledge on support) or another appropriate library. If necessary I would be willing to use one lib for doc and another for docx. Thanks.

• Compile C++ program on Mac to run on Linux

  - by mav

  I have an application that I wrote in C++/SDL, using FMOD library. The app is portable and compiles without any code change on Mac and on Linux. But one annoyance is that when I want to ship Linux version, I have to run my Linux box, copy the source code over there (over USB drive, because I have no network there, it's an old laptop) and compile it, then copy it again over USB to my Mac and upload it. My question is - is there a better way of doing it? Ideally, could I compile the app to run on Linux directly from Xcode, where I compile it for Mac?

• Not Seeing Ajax Requests In Firebug If Header Has Been Modified

  - by FluidFoundation

  Hey braintrust, I'm making an ajax call using jQuery's library to an api, which requires a username and password encoded to base64 be added to the header. here's a basic example: $.ajax({ type: "GET", contentType: 'application/json', beforeSend:function(xhr){ xhr.setRequestHeader("Authentication", "Basic " + base64EncodedValue); } url: 'https://api.company.com/uri/', complete: function(result) { alert(result); } }); But when this fires off, I get a black alert box, so it doesn't appear as if something is coming back. There is no log in the Firebug console that a get ajax request was done. However, if I remove the beforeSend option, I do see the ajax request get logged, but the request gets back a 'not authorized', so it definitely hit the right place. Any ideas on why it's not showing up in Firebug so I can verify the headers are being sent out correctly?

• Limitation of Attachment size when using SMTP

  - by Gas Gemba

  Hi, I wrote a C++ program to send a mail using SMTP. But when I attach any files I notices that a single file's size always is limited to 808 bytes. As an example if I send a text file with 10 KBs, when I download the attachment it has only text worth 808 bytes. If the large file is a zip file, it gets corrupted in unzipping obviously due to CRC failure. I used a MAPI library to send larger files without a problem. Is this a network limitation of SMTP? Can someone please explain why this is happening?? Thank You!!!

• How to evaluate javascript code in Python

  - by overboming

  I need to fetch some result on a webpage, which use some javascript code to generate the part I am interesting in like following eval(function(p,a,c,k,e,d){e=function(c){return c};if(!''.replace(/^/,String)){while(c--)d[c]=k[c]||c;k=[function(e){return d[e]}];e=function(){return'\\w+'};c=1;};while(c--)if(k[c])p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c]);return p;}('5 11=17;5 12=["/3/2/1/0/13.4","/3/2/1/0/15.4","/3/2/1/0/14.4","/3/2/1/0/7.4","/3/2/1/0/6.4","/3/2/1/0/8.4","/3/2/1/0/10.4","/3/2/1/0/9.4","/3/2/1/0/23.4","/3/2/1/0/22.4","/3/2/1/0/24.4","/3/2/1/0/26.4","/3/2/1/0/25.4","/3/2/1/0/18.4","/3/2/1/0/16.4","/3/2/1/0/19.4","/3/2/1/0/21.4"];5 20=0;',10,27,'40769|54|Images|Files|png|var|imanhua_005_140430179|imanhua_004_140430179|imanhua_006_140430226|imanhua_008_140430242|imanhua_007_140430226|len|pic|imanhua_001_140429664|imanhua_003_140430117|imanhua_002_140430070|imanhua_015_140430414||imanhua_014_140430382|imanhua_016_140430414|sid|imanhua_017_140430429|imanhua_010_140430289|imanhua_009_140430242|imanhua_011_140430367|imanhua_013_140430382|imanhua_012_140430367'.split('|'),0,{})) The result of eval() is valuable to me, I am writing a Python script, is there any library I can use to virtually run this piece of javascript code and get the output?

• zend framework error

  - by Huy

  I started getting the following error today, but don't know why and what caused it. [31-May-2010 03:52:10] PHP Fatal error: Cannot run code from this file in conjunction with non encoded files in ZendFramework-1.10.5/library/Zend/Validate/Hostname/Com.php on line 547 I'm using zend framework version 1.10.5; although version 1.09 also has the same problem. I only get this error in my production server, and cannot duplicate it from anywhere else. Also note that I only get this error when I submit form with recaptcha. If I remove recaptcha, it works fine. Any help is appreciated.

• ImageMagick: Tiff to PDF from PHP

  - by Sheldon

  How can I convert 2 tiff images to PDF, I already knows how to get the image out of the DB, and I print it using echo and setting up the MIME type. But, right know I need to use a duplex printer option, so I need a way to generate a PDF from inside my PHP page, that PDF must containt both TIFF images (one per page) How can I do that? What do I need for php to work with that library. Thank you very much. EDIT: Is a self hosted app, I own the server (actually I'm using WAMP 2). I extract the images from the MySQL DB (stored using LONGBLOBS).

• Weird Workflow Behavior in Sharepoint 2007

  - by frbry

  I have a Document Library A and a list B. When a document added to A, an item is created in B with the Title = A.Url. Another workflow runs whenever a document is updated in A which makes a lookup: B.Title = A.Url, and changes another column in B in found item. Item Change Workflow always gives "Error Occurred: List item is not found". I modified the workflow to send me an e-mail containing the new (but unchanged) A.Url. It sent me the exact string with the one already in list B. Anyways, why it can't find the item when the two columns are equal? Thanks in advance. Edit I literally hate Microsoft Sharepoint.

• REST authentication internal project (iPhone to grails app) using 2 legged oauth?

  - by Rael

  Hi, I'm creating an iPhone project, and will be communicating with a server via REST. I will be sending push notifications, initiated from another service. I would like to authenticate all communication from the iPhone to my server (e.g., synchronising notifications with the server as the push request is not guaranteed to go through) 2 legged Oauth seems to be the ideal solution, however there is not a lot of information regarding it, especially as most of the libraries seem to be oriented towards consumers and not providers. What library should I use? Is Oauth overkill? If so what do you recommend? I'm looking for the simplest possible solution at the moment; If it is going to take me more than a week to implement Oauth, it's simply not worth it. Thanks

• How many layers are between my program and the hardware?

  - by sub

  I somehow have the feeling that modern systems, including runtime libraries, this exception handler and that built-in debugger build up more and more layers between my (C++) programs and the CPU/rest of the hardware. I'm thinking of something like this: 1 + 2 OS top layer Runtime library/helper/error handler a hell lot of DLL modules OS kernel layer Do you really want to run 1 + 2?-Windows popup (don't take this serious) OS kernel layer Hardware abstraction Hardware Go through at least 100 miles of circuits Eventually arrive at the CPU ADD 1, 2 Go all the way back to my program Nearly all technical things are simply wrong and in some random order, but you get my point right? How much longer/shorter is this chain when I run a C++ program that calculates 1 + 2 at runtime on Windows? How about when I do this in an interpreter? (Python|Ruby|PHP) Is this chain really as dramatic in reality? Does Windows really try "not to stand in the way"? e.g.: Direct connection my binary < hardware?

• How do I watch a file for changes using Python?

  - by Jon Cage

  I have a log file being written by another process which I want to watch for changes. Each time a change occurrs I'd like to read the new data in to do some processing on it. What's the best way to do this? I was hoping there'd be some sort of hook from the PyWin32 library. I've found the win32file.FindNextChangeNotification function but have no idea how to ask it to watch a specific file. If anyone's done anything like this I'd be really grateful to hear how... [Edit] I should have mentioned that I was after a solution that doesn't require polling. [Edit] Curses! It seems this doesn't work over a mapped network drive. I'm guessing windows doesn't 'hear' any updates to the file the way it does on a local disk.

• Different formats of OpenIDs

  - by mecablaze

  stackoverflow, I am experimenting with implementing OpenID in my existing site. I have looked at Plaxo's article on this very subject and I'm a mite confused about something. I am using this PHP OpenID library. I have some code running, and I am getting a unique OpenID back. From myopenid.com, I am getting an id that looks like https://mecablaze.myopenid.com/ But from Yahoo and Google, I am getting an ID that much more cryptic, e.g. https://www.google.com/accounts/o8/id?id=AItOawlbp1cxujdJWDnpx72xVROOw-5V_WzIDZA Are Google's and Yahoo's "gibberish" ids unique for every login user, i.e. is this the value that I use to tie in with existing user on my web app?

• Need help understanding _set_security_error_handler()

  - by Emil D

  So , I've been reading this article: http://msdn.microsoft.com/en-us/library/aa290051%28VS.71%29.aspx And I would like to define my custom handler.However, I'm not sure I understand the mechanics well.What happens after a call is made to the user-defined function ( e.g. the argument of _set_security_error_handler() ) ? Does the program still terminate afterward ? If that is the case, is it possible to terminate only the current thread(assuming that it is not the main thread of the application).AFAIK, each thread has its own stack , so if the stack of a thread gets corrupted, the rest of the application shouldn't be affected. Finally, if it is indeed possible to only terminate the current thread of execution, what potential problems could such an action cause? I'm trying to do all this inside an unmanaged C++ dll that I would like to use in my C# code.

• Coding Standards

  - by kevchadders

  For those of us that have programmed enough I’m sure we have come across many different flavours of coding standards that you can use when it comes to programming. e.g. http://msdn.microsoft.com/en-us/library/ms229042.aspx You might derive your coding standards for the current company you work for or from the original author of the code you’re working on. Coding styles are often used for specific program languages and some styles in one coding language might not be considered appropriate for others. Of course some coding standards can be applied across many different program languages. My question is do you have any good advice/links yourselves to a set of coding standards that you would recommend to others, or best practices to follow? Thank you for your time. EDIT: As we know there are many related articles on this subject, but C# Coding standard / Best practices in SO has some very useful links in there which is worth a visit. (Check out the 2 links on .NET/C# guidelines by ESV - Accepted Answer)

• How to draw the "trail" in a maze solving application

  - by snow-spur

  Hello i have designed a maze and i want to draw a path between the cells as the 'person' moves from one cell to the next. So each time i move the cell a line is drawn Also i am using the graphics module The graphics module is an object oriented library Im importing from graphics import* from maze import* my circle which is my cell center = Point(15, 15) c = Circle(center, 12) c.setFill('blue') c.setOutline('yellow') c.draw(win) p1 = Point(c.getCenter().getX(), c.getCenter().getY()) this is my loop if mazez.blockedCount(cloc)> 2: mazez.addDecoration(cloc, "grey") mazez[cloc].deadend = True c.move(-25, 0) p2 = Point(getX(), getY()) line = graphics.Line(p1, p2) cloc.col = cloc.col - 1 Now it says getX not defined every time i press a key is this because of p2???

• What should I really release as open source when I use Berkeley DB (JE)?

  - by Ersin Er

  The Berkeley DB (JE) license information says: "...Redistributions in any form must be accompanied by information on how to obtain complete source code for the DB software and any accompanying software that uses the DB software.... For an executable file, complete source code means the source code for all modules it contains. It does not include source code for modules or files that typically accompany the major components of the operating system on which the executable file runs." If I build an abstraction level on top of BDB JE, should I open source only that library or any software that uses BDB JE indirectly?

• Determine compile options from load module - IBM Enterprise COBOL

  - by NealB

  How can I determine the compile options used to compile an IBM Enterprise COBOL program by looking at the load module? When a dump is issued they are listed as follows: Compile Options for PROGXX: ADV, ARITH(COMPAT), AWO, NOCICS, CODEPAGE(01140), DATA(31), NODATEPROC, NODBCS, NODLL, NODYNAM, NOEXPORTALL, NOFASTSRT, INTDATE(LILIAN), NUMPROC(NOPFD), NOOPTIMIZE, OUTDD(SYSOUT), PGMNAME(COMPAT), RENT, RMODE(AN NOSQL, SQLCCSID, SSRANGE, NOTEST, NOTHREAD, TRUNC(OPT), XMLPARSE(XMLSS), YEARWINDOW(1900), ZWB so I presume they must be tucked away somewhere in the load module. I want to scan a load library checking that each load was compiled with some specific options to ensure compliance to shop standard (eg. SSRANGE). Any ideas would be appreciated.

• Choosing between YUI Charts or Google Visualization API

  - by r2b2

  Hello , I'm a bit stuck with which charting library I will use in my project. Im stuck with this two (but also open for other suggestions) For YUI Charts : Pro : - Very robust and configurable Cons : - Uses flash 9 , which might potentially be inaccessible for users without up to date flash version - Does not support export to image (for flash versions < 10 only) For Google Visualization API pros: - small file size for the libraries, - can be exported to static image charts (via separate API call) Cons - limited configuration options So there, please help me decide. YUI charts has the edge over configuration options but Google Visualization API has the edge in terms of accessibility as it uses SVG to render the grapsh instead of Flash. For users that are hand-cuffed by corporate IT prohibitions , they cant just upgrade their Flash version and the page will not work. Thanks!

• Redirect Using htaccess

  - by manyxcxi

  I am trying to redirect /folder to / using .htaccess but all am I getting is the Apache HTTP Server Test Page. My root directory looks like this: / .htaccess -/folder -/folder2 -/folder3 My .htaccess looks like this: RewriteEngine On RewriteCond %{REQUEST_URI} !^/folder/ RewriteRule ^(.*)$ folder/$1 [L] What am I doing wrong? I checked my httpd.conf (I'm running Centos 5.3) and the mod_rewrite library is being loaded. As a side note, my server is not a www server, its simply a virtual machine so its hostname is centosvm. Addition: I have found that the mod_rewrite module is loaded, but none of my .htaccess redirects seem to be working.

• Sphinx non-fulltext, integer only search

  - by James

  Hello guys, I've got a few tables that literally only hold integers, no "words" and for some reason Sphinx is unable to hold this data in it's library. Just returns "0 bytes" errors for these indexes. Is it possible to do this? If so, how? Below is an example from my Sphinx.conf for one that fails. source track { type = mysql sql_host = host sql_user = user sql_pass = pass sql_db = db sql_port = port sql_query = SELECT id, user, time FROM track; sql_attr_uint = user sql_attr_uint = time sql_query_info = SELECT * FROM track WHERE id=$id } index track { source = track path = /var/lib/sphinx/track docinfo = extern charset_type = utf-8 min_prefix_len = 1 enable_star = 1 }

• WPF Custom Control with Image problem

  - by user311883

  Hi all, I am quite new to WPF/XAML and I am currently facing a problem. I have a solution with two projects in it, the first project is a Custom Control Library with a custom Window form control inside. The second project is a WPF application using my custom window form. All work fine except for the form Icon. In the WPF application project I set my window icon property to "/ProjectTwoNameSpace;component/Resources/Images/Film.ico", and in the WPF custom control I try to show that image that way : <Image Grid.Column="0" Margin="3" Width="27" Height="27"> <Image.Source> <BitmapImage UriSource="{Binding Path=Icon}" /> </Image.Source> </Image> But it doesn't work, I get a error at runtime saying that the property UriSource or StreamSource must be set for my tag. Anyone can help me ? I think it's jsut a WPF newbie problem ^^

• git hooks - regenerate a file and add it to each commit ?

  - by egarcia

  I'd like to automatically generate a file and add it to a commit if it has changed. Is it possible, if so, what hooks should I use? Context: I'm programming a CSS library. It has several CSS files, and at the end I want to produce a compacted and minimized version. Right now my workflow is: Modify the css files x.css and y.css git add x.css y.css Execute minimize.sh which parses all the css files on my lib, minimizes them and produces a min.css file git add min.css git commit -m 'modified x and y doing foo and bar' I would like to have steps 3 and 4 done automatically via a git hook. Is that possible? I've never used git hooks before. After reading the man page, I think I need to use the @pre-commit@ hook. But can I invoke git add min.css, or will I break the internet?

• tchar safe functions -- count parameter for UTF-8 constants

  - by Dustin Getz

  I'm porting a library from char to TCHAR. the count parameter of this fragment, according to MSDN, is the number of multibyte characters, not the number of bytes. so, did I get this right? _tcsncmp(access, TEXT("ftp"), 3); //or do i want _tcsnccmp? "Supported on Windows platforms only, _mbsncmp and _mbsnbcmp are multibyte versions of strncmp. _mbsncmp will compare at most count multibyte characters and _mbsnbcmp will compare at most count bytes. They both use the current multibyte code page. _tcsnccmp and _tcsncmp are the corresponding Generic functions for _mbsncmp and _mbsnbcmp, respectively. _tccmp is equivalent to _tcsnccmp."

• Is the MySQL FOSS License Exception transitive - does it remove the GPL restrictions for downstream

  - by Eric

  I'm looking at building a MySQL client plugin for a proprietary product, which would violate the GPL as discussed in the FAQ at http://www.gnu.org/licenses/gpl-faq.html#NFUseGPLPlugins However, according to the MySQL FOSS License Exception ("FLE"), discussed at http://www.mysql.com/about/legal/licensing/foss-exception/, you can license an open-source product built with the client with many alternatives. The oursql library (https://launchpad.net/oursql) is BSD-licensed. Is this a valid way around the GPL? By my reading of the FLE, the only clause that refers to downstream uses of derived works is section 2.e: All works that are aggregated with the Program or the Derivative Work on a medium or volume of storage are not derivative works of the Program, Derivative Work or FOSS Application, and must reasonably be considered independent and separate works. This is the case for our product: it is not a derivative work of oursql, and in fact accesses it only via a plugin-driven interface. So is this a valid loophole?
