Preventing user from inserting *

- by user990635

I'm trying to prevent user from inserting * in a textbox. This is what I was trying to do, but here it only detects * if this is the only inserted character. For example texts like: *, etc. When allowed characters are mixed with *, then it cannot detect it. For example inputs such as: *hjh, etc.. and maybe how to make it replace only * with "" and not the whole field? <script type="text/javascript"> function testField(field) { var regExpr = new RegExp("[^*]"); if(!regExpr.test(field.value)) { field.value = ""; } } </script> <input type="text" id="searchGamesKeyword" class="searchGamesTextBox" name="searchGamesKeyword" onblur="testField(this);" />

writing terminal output to file

- by user1551817

On my machine, I have some software which takes commands in the terminal and returns a list of values. To run it, I have to type something like: pdv -t filename I am trying to run it as part of a python programme. When I run the following: os.system('pdv -t %s' % (epoch_name)) then I get the values that I desire returned to my terminal (where epoch_name is the variable name for the filename). But when I try to write the result to a file: os.system('pdv -t %s % "(epoch_name)" > 123.txt') the file 123.txt is produced but it is empty. I know that I am misplacing the " and/or ' characters, but I can't figure out where they should go. Any help would be gratefully received!

CURL login by script to a Joomla website

- by Paryeshakaya

Hello, I need to login by a PHP script that uses CURL to a Joomla website, in order to access to a private page that needs to be processed, but nothwithstanding several attempts I have done, I have always a 403 error. I have done a similar thing with other websites and it worked. Script I use: $uname = "id"; $upswd = "pswd"; $url = "http://www.somewebpage.com"; $agent = "'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6'"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url ); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE ); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE ); curl_setopt($ch, CURLOPT_COOKIEJAR, './cookie.txt'); curl_setopt($ch, CURLOPT_COOKIEFILE, './cookie.txt'); curl_setopt($ch, CURLOPT_USERAGENT, $agent ); curl_setopt($ch, CURLOPT_HEADER, TRUE ); curl_setopt($ch, CURLOPT_REFERER, $url1); // POST fields $postfields = array(); $postfields['username'] = urlencode($uname); $postfields['passwd'] = urlencode($upswd); $postfields['remember'] = 'yes'; $postfields['option'] = 'login'; $postfields['op2'] = 'login'; $postfields['return'] = urlencode($url); $postfields['message'] = '0'; $postfields['force_session'] = '1'; $postfields['j3b00d36f4336137f4f03335c5eee6440'] = '1'; curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields); $ret = curl_exec($ch); The username and password, as well as the website URL I am using are perfectly working. This is the result I get: HTTP/1.1 100 Continue HTTP/1.1 403 Forbidden Date: Sat, 06 Feb 2010 08:29:36 GMT Server: Apache/2.2.13 (Unix) mod_ssl/2.2.13 OpenSSL/0.9.7a DAV/2 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 X-Powered-By: PHP/5.2.10 Connection: close Transfer-Encoding: chunked Content-Type: text/html Is there something wrong in my CURL request? Or is there a limit with Joomla remote login? Thanks for suggestions!

Wordpress 403/404 Errors: You don't have permission to access /wp-admin/themes.php on this server

- by Glen

Some background: I setup six blogs this week, all using Wordpress 2.92, installed with Fantastico on a baby croc plan with Hostgator. I used the same theme (heatmap 2.5.4) and plugins for each blog. They were all up and running, no issues at all. I go to create a new blog this morning, using the same setup, and when I try to change the theme settings, I get the following error: Forbidden You don't have permission to access /wp-admin/themes.php on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. Apache/2.2.15 (Unix) mod_ssl/2.2.15 OpenSSL/0.9.8n DAV/2 mod_fcgid/2.3.5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at http://www.mydomain.com Port 80 I tried uninstalling WP and doing a clean install, still the same issue with a clean installation. So I went back and checked the six other blogs that I had setup over the last week or so, and they are also now giving me 403 or 404 errors when trying to change theme settings, and everytime there's an error it points to either themes.php or functions.php At this point I'm at my wits end trying to figure out what the problem is. Hostgator support looked at it and thought maybe it was a permissions issue but they reset those and I'm still having the problem. At first I thought the problem might have been related to a plugin I recently installed on the previous six blogs that morning (ByREV Fix Missed Shedule Plugin) to deal with a missed schedule bug with WP 2.92, and that maybe that had mucked things up. But then I checked a blog I built months ago, also using the same theme and plugins, and now it too is also encountering the same problem. Any ideas? I tried deleting my htaccess, uploading a blank one, uploading one with this snippet I found on the hostgator forum: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress Nothing has worked. I still get 403 or 404 errors everytime. Everything was working perfectly yesterday so I know this setup DOES WORK, I've just mucked something up somewhere and I'm clueless what it is. I read a related thread here and tried chmoding the wp-content folder to 0755 and still having the issue. Any thoughts? Thanks!

.htaccess blocking images on some internal pages

- by jethomas

I'm doing some web design for a friend and I noticed that everywhere else on her site images will load fine except for the subdirectory I'm working in. I looked in her .htaccess file and sure enough it is setup to deny people from stealing her images. Fair Enough, except the pages i'm working on are in her domain and yet I still get the 403 error. I'm pasting the .htaccess contents below but I replaced the domain names with xyz, 123 and abc. So specifically the page I'm on (xyz.com/DesignGallery.asp) pulls images from (xyz.com/machform/data/form_1/files) and it results in a forbidden error. RewriteEngine on <Files 403.shtml> order allow,deny allow from all </Files> RewriteCond %{HTTP_REFERER} !^http://xyz.com/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://xyz.com/machform/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://xyz.com/machform/data/form_1/files/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://xyz.com$ [NC] RewriteCond %{HTTP_REFERER} !^http://abc.com/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://abc.com$ [NC] RewriteCond %{HTTP_REFERER} !^http://abc.xyz.com/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://abc.xyz.com$ [NC] RewriteCond %{HTTP_REFERER} !^http://123.com/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://123.com$ [NC] RewriteCond %{HTTP_REFERER} !^http://123.xyz.com/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://123.xyz.com$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.xyz.com/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.xyz.com/machform/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.xyz.com/machform/$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.xyz.com/machform/data/form_1/files/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.xyz.com$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.abc.com/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.abc.com$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.abc.xyz.com/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.abc.xyz.com$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.123.com/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.123.com$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.123.xyz.com/.*$ [NC] RewriteCond %{HTTP_REFERER} !^http://www.123.xyz.com$ [NC] RewriteRule .*\.(jpg|jpeg|gif|png|bmp)$ - [F,NC] deny from 69.49.149.17 RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^vendors\.html$ "http\:\/\/www\.xyz\.com\/Design_Gallery_1\.htm" [R=301,L] RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^vendors\.asp$ "http\:\/\/www\.xyz\.com\/Design_Gallery_1\.htm" [R=301,L] RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^ArtGraphics\.html$ "http\:\/\/www\.xyz\.com\/Art_Gallery_1\.htm" [R=301,L] RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^ArtGraphics\.asp$ "http\:\/\/www\.xyz\.com\/Art_Gallery_1\.htm" [R=301,L] RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^Gear\.asp$ "http\:\/\/www\.xyz\.com\/Gear_Gallery_1\.htm" [R=301,L] RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^Gear\.html$ "http\:\/\/www\.xyz\.com\/Gear_Gallery_1\.htm" [R=301,L] RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^NewsletterSign\-Up\.html$ "http\:\/\/www\.xyz\.com\/Newsletter\.htm" [R=301,L] RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^NewsletterSign\-Up\.asp$ "http\:\/\/www\.xyz\.com\/Newsletter\.htm" [R=301,L] RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^KidzStuff\.html$ "http\:\/\/www\.xyz\.com\/KidzStuff1\.htm" [R=301,L] RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^KidzStuff\.asp$ "http\:\/\/www\.xyz\.com\/KidzStuff1\.htm" [R=301,L] RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^Vendors\.html$ "http\:\/\/www\.xyz\.com\/Design_Gallery_1\.htm" [R=301,L] RewriteCond %{HTTP_HOST} ^.*$ RewriteRule ^Vendors\.asp$ "http\:\/\/www\.xyz\.com\/Design_Gallery_1\.htm" [R=301,L]

Mac OS - Built SVN from source, now Apache2 not loading sites

- by Geuis

This relates to another question I asked earlier today. I built SVN 1.6.2 from source. In the process, it has completely screwed up my dev environment. After I built SVN, Apache wasn't loading. It was giving me this error: Syntax error on line 117 of /private/etc/apache2/httpd.conf: Cannot load /usr/libexec /apache2/mod_dav_svn.so into server: dlopen(/usr/libexec/apache2/mod_dav_svn.so, 10): no suitable image found. Did find:\n\t/usr/libexec/apache2/mod_dav_svn.so: mach-o, but wrong architecture It appears that SVN over-wrote the old mod_dav_svn.so and I am not able to get it to build as FAT, and I can't recover whatever was originally there. I resolved this(temporarily?) by commenting out the line that was loading the mod_dav_svn.so and got Apache to start at this point. However, even though Apache is running I am now getting this error when trying to access my dev sites: Directory index forbidden by Options directive: /usr/share/tomcat6/webapps/ROOT/ I have Apache2 sitting in front of Tomcat6. I access my local dev site using the internal name "http://localthesite". I have had virtual directories set up that have worked until this SVN debacle. Tomcat is installed at /usr/local/apache-tomcat, and webapps is /usr/local/apache-tomcat/webapps. Our production servers deploy tomcat to /usr/share/tomcat6, so I have symlinks setup on my system to replicate this as well. These point back to the actual installation path. This has all been working fine as well. None of our configurations for Apache2, Tomcat, or .htaccess have changed. Over the weekend, I performed a "Repair Disk Permissions" on the system. This was before I discovered the mod_dav_svn.so problem. I have been reading up on this all morning and the most common answer is that there is an Options -Indexes set. We have this in a config file, but it was there before and when I removed it during testing, I still got the same errors from Apache. At this point, I'm assuming I either totally borked the native Apache2 installation on this Mac, or that there is a permissions error somewhere that I'm missing. The permissions error could be from the SVN installation, or from my repair process. Does anyone have any idea what could be the problem? I'm totally blocked right now and have no idea where to check next.

How Can I Populate Default Form Data with a ManyToMany Field?

- by b14ck

Ok, I've been crawling google and Django documentation for over 2 hours now (as well as the IRC channel on freenode), and haven't been able to figure this one out. Basically, I have a model called Room, which is displayed below: class Room(models.Model): """ A `Partyline` room. Rooms on the `Partyline`s are like mini-chatrooms. Each room has a variable amount of `Caller`s, and usually a moderator of some sort. Each `Partyline` has many rooms, and it is common for `Caller`s to join multiple rooms over the duration of their call. """ LIVE = 0 PRIVATE = 1 ONE_ON_ONE = 2 UNCENSORED = 3 BULLETIN_BOARD = 4 CHILL = 5 PHONE_BOOTH = 6 TYPE_CHOICES = ( ('LR', 'Live Room'), ('PR', 'Private Room'), ('UR', 'Uncensored Room'), ) type = models.CharField('Room Type', max_length=2, choices=TYPE_CHOICES) number = models.IntegerField('Room Number') partyline = models.ForeignKey(Partyline) owner = models.ForeignKey(User, blank=True, null=True) bans = models.ManyToManyField(Caller, blank=True, null=True) def __unicode__(self): return "%s - %s %d" % (self.partyline.name, self.type, self.number) I've also got a forms.py which has the following ModelForm to represent my Room model: from django.forms import ModelForm from partyline_portal.rooms.models import Room class RoomForm(ModelForm): class Meta: model = Room I'm creating a view which allows administrators to edit a given Room object. Here's my view (so far): def edit_room(request, id=None): """ Edit various attributes of a specific `Room`. Room owners do not have access to this page. They cannot edit the attributes of the `Room`(s) that they control. """ room = get_object_or_404(Room, id=id) if not room.is_owner(request.user): return HttpResponseForbidden('Forbidden.') if is_user_type(request.user, ['admin']): form_type = RoomForm elif is_user_type(request.user, ['lm']): form_type = LineManagerEditRoomForm elif is_user_type(request.user, ['lo']): form_type = LineOwnerEditRoomForm if request.method == 'POST': form = form_type(request.POST, instance=room) if form.is_valid(): if 'owner' in form.cleaned_data: room.owner = form.cleaned_data['owner'] room.save() else: defaults = {'type': room.type, 'number': room.number, 'partyline': room.partyline.id} if room.owner: defaults['owner'] = room.owner.id if room.bans: defaults['bans'] = room.bans.all() ### this does not work properly! form = form_type(defaults, instance=room) variables = RequestContext(request, {'form': form, 'room': room}) return render_to_response('portal/rooms/edit.html', variables) Now, this view works fine when I view the page. It shows all of the form attributes, and all of the default values are filled in (when users do a GET)... EXCEPT for the default values for the ManyToMany field 'bans'. Basically, if an admins clicks on a Room object to edit, the page they go to will show all of the Rooms default values except for the 'bans'. No matter what I do, I can't find a way to get Django to display the currently 'banned users' for the Room object. Here is the line of code that needs to be changed (from the view): defaults = {'type': room.type, 'number': room.number, 'partyline': room.partyline.id} if room.owner: defaults['owner'] = room.owner.id if room.bans: defaults['bans'] = room.bans.all() ### this does not work properly! There must be some other syntax I have to use to specify the default value for the 'bans' field. I've really been pulling my hair out on this one, and would definitely appreciate some help. Thanks!

Display all images from outside web root folder using PHP

Parameters not being passed into template when using the .Net transform classes

- by Chris F

I am using the .Net XslCompiledTranform to run some simple XSLT (see below for a simplified example). The example XSLT is meant to do simply show the value of the parameter that is passed in to the template. The output is what I expect it to be (i.e. <result xmlns:p1="http://www.doesnotexist.com"> <valueOfParamA>valueA</valueOfParamA> </result> when I use Saxon 9.0, but when I use XslCompiledTransform (XslTransform) in .net I get <result xmlns:p1="http://www.doesnotexist.com"> <valueOfParamA></valueOfParamA> </result> The problem is that that the parameter value of paramA is not being passed into the template when I use the .Net classes. I completely stumped as to why. when I step through in Visual Studio, the debugger says that the template will be called with paramA='valueA' but when execution switches to the template the value of paramA is blank. Can anyone explain why this is happening? Is this a bug in the MS implementation or (more likely) am I doing something that is forbidden in XSLT? Any help greatly appreciated. This is the XSLT that I am using <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:extfn="http://exslt.org/common" exclude-result-prefixes="extfn" xmlns:p1="http://www.doesnotexist.com">  <xsl:output method="xml" indent="yes"/> <xsl:template match="/"> <xsl:variable name="resultTreeFragment"> <p1:foo> </p1:foo> </xsl:variable> <xsl:variable name="nodeset" select="extfn:node-set($resultTreeFragment)"/> <result> <xsl:apply-templates select="$nodeset" mode="AParticularMode"> <xsl:with-param name="paramA" select="'valueA'"/> </xsl:apply-templates> </result> </xsl:template> <xsl:template match="@* | node()" mode="AParticularMode"> <xsl:param name="paramA"/> <valueOfParamA> <xsl:value-of select="$paramA"/> </valueOfParamA> </xsl:template> </xsl:stylesheet>

Flatten date range memberships retaining only the highest priority membership (TRANSACT-SQL)

- by shadowranger

Problem statement: A table contains an item_id, a category_id and a date range (begin_date and end_date). No item may be in more than one category on any given date (in general; during daily rebuilding it can be in an invalid state temporarily). By default, all items are added (and re-added if removed) to a category (derived from outside data) automatically on a daily basis, and their membership in that category matches the lifespan of the item (items have their own begin and end date, and usually spend their entire lives in the same category, which is why this matches). For items in category X, it is occasionally desirable to override the default category by adding them to category Y. Membership in category Y could entirely replace membership in category X (that is, the begin and end dates for membership in category Y would match the begin and end dates of the item itself), or it could override it for an arbitrary period of time (at the beginning, middle or end the item's lifespan, possibly overriding for short periods at multiple times). Membership in category Y is not renewed automatically and additions to that category is done by manual data entry. Every day, when category X is rebuilt, we get an overlap, where any item in category Y will now be in category X as well (which is forbidden, as noted previously). Goal: After each repopulation of category X (which is done in a rather complicated and fragile manner, and ideally would be left alone), I'm trying to find an efficient means of writing a stored procedure that: Identifies the overlaps Changes existing entries, adds new ones where necessary (such as in the case where an item starts in category X, switches to category Y, then eventually switches back to category X before ending), or removes entries (when an item is in category Y for its entire life) such that every item remains in category Y (and only Y) where specified, while category X membership is maintained when not overridden by category Y. Does not affect memberships of categories A, B, C, Z, etc., which do not have override categories and are built separately, by completely different rules. Note: It can be assumed that X membership covers the entire lifespan of the item before this procedure is called, so it is unnecessary to query any data outside this table. Bonus credit: If for some reason there are two adjacent or overlapping memberships in for the same item in category Y, stitching them together into a single entry is appreciated, but not necessary. Example: item_id category_id begin_date end_date 1 X 20080101 20090628 1 Y 20090101 20090131 1 Y 20090601 20090628 2 X 20080201 20080731 2 Y 20080201 20080731 Should become: item_id category_id begin_date end_date 1 X 20080101 20081231 1 Y 20090101 20090131 1 X 20090201 20090531 1 Y 20090601 20090628 2 Y 20080201 20080731 If it matters, this needs to work on SQL Server 2005 and SQL Server 2008

How is "clean" testing done on the Macintosh without virtualization?

- by Schnapple

One of the things I've run across on Windows is when a web browser plugin or program you're developing makes an assumption that something is installed that, by default, isn't always present on Windows. A perfect example would be .NET - a whole lot of people running Windows XP have never installed any versions of .NET and so the installer needs to detect and remedy this if necessary. The way I've been testing this in Windows is to have a virtual machine with a snapshot of a clean, patched, but otherwise untouched install of XP or Vista or 7 or whatever. When I'm done testing I just discard any changes since the snapshot. Works great. I'm now developing something for the Macintosh, a platform which is very new to me, and I'm seeing that virtualization does not appear to be an option. It's explicitly forbidden in the EULA of Mac OS X, it's only allowed from Mac OS X Server, which seeing as how I'm targeting an end product is of no use to me, and the one program I see which can virtualize it - VirtualBox - only supports the server and actively nukes any discussion of running the consumer/client version of Mac OS X. And the only instructions I find anywhere on the topic seem to involve the use of "hacking" programs which is very much incompatible with the full-time gig I'm trying to do this for. So it looks like virtualization is out, but at various points I'm going to want or need to simulate what it's like to install and run this software on a "clean" Macintosh. How do people usually do this? Just buy multiple Macintoshes and use Time Machine? Am I thinking about this all wrong and everything Just Works? To be clear I'm not trying to run Mac OS X on a Windows machine. I have a Macintosh, I'm fine with virtualizing Mac OS X on Apple hardware, I'm just not seeing a route to making the non-Server version do this. I'm aware that Mac OS X Server can be virtualized but that's not what I'm going for. I'm aware that there are unsanctioned/unsupported methods of making Mac OS X run in virtualization programs like VirtualBox but for legal reasons I am not interested in those. My question is not "how can I do this?" but rather "so this thing I do on Windows seems to not be possible, generally, on the Macintosh, so what do people do to achieve what I'm going for?"

WebRequest request = WebRequest.Create("http://mydomain.com/cms/csharptest.php"); request.Credentials = new NetworkCredential("myUser", "myPass"); // Set the Method property of the request to POST. request.Method = "POST"; // Create POST data and convert it to a byte array. string postData = "name=PersonName&age=25"; byte[] byteArray = Encoding.UTF8.GetBytes(postData); // Set the ContentType property of the WebRequest. request.ContentType = "application/x-www-form-urlencoded"; // Set the ContentLength property of the WebRequest. request.ContentLength = byteArray.Length; // Get the request stream. Stream dataStream = request.GetRequestStream(); // Write the data to the request stream. dataStream.Write(byteArray, 0, byteArray.Length); // Close the Stream object. dataStream.Close(); // Get the response. HttpWebResponse response = (HttpWebResponse)request.GetResponse(); // Display the status. Console.WriteLine((response).StatusDescription); // Get the stream containing content returned by the server. dataStream = response.GetResponseStream(); // Open the stream using a StreamReader for easy access. StreamReader reader = new StreamReader(dataStream); // Read the content. string responseFromServer = reader.ReadToEnd(); // Display the content. Console.WriteLine(responseFromServer); // Clean up the streams. reader.Close(); dataStream.Close(); response.Close(); The directory cms/ requires authentication, but if I try running this same code somewhere, where authentication isn't needed, it works fine. The error (System.Net.WebException: The remote server returned an error: (403) Forbidden) occurs at HttpWebResponse response = (HttpWebResponse)request.GetResponse(); I have managed in reading data after authenticating, but not if I also send POST data. What's wrong with this?

Getting 404 when attempting to POST file to Google Cloud Storage from service account

- by klactose

I'm wondering if anyone can tell me the proper syntax & formatting for a service account to send a POST Object to bucket request? I'm attempting it programmatically using the HttpComponents library. I manage to get a token from my GoogleCredential, but every time I construct the POST request, I get: HTTP/1.1 403 Forbidden <?xml version='1.0' encoding='UTF-8'?><Error><Code>AccessDenied</Code><Message>Access denied.</Message><Detailsbucket-name</Details></Error The Google documentation that describes the request methods, mentions posting using html forms, but I'm hoping that wasn't suggesting the ONLY way to get the job done. I know that HttpComponents has a way to explicitly create form data by using UrlEncodedFormEntity, but it doesn't support multipart data. Which is why I went with using the MultipartEntity class. My code is below: MultipartEntity entity = new MultipartEntity( HttpMultipartMode.BROWSER_COMPATIBLE ); String token = credential.getAccessToken(); entity.addPart("Authorization", new StringBody("OAuth " + token)); String date = formatDate(new Date()); entity.addPart("Date", new StringBody(date)); entity.addPart("Content-Encoding", new StringBody("UTF-8")); entity.addPart("Content-Type", new StringBody("multipart/form-data")); entity.addPart("bucket", new StringBody(bucket)); entity.addPart("key", new StringBody("fileName")); entity.addPart("success_action_redirect", new StringBody("/storage")); File uploadFile = new File("pathToFile"); FileBody fileBody = new FileBody(uploadFile, "text/xml"); entity.addPart("file", fileBody); httppost.setEntity(entity); System.out.println("Posting URI = "+httppost.toString()); HttpResponse response = client.execute(httppost); HttpEntity resp_entity = response.getEntity(); As I mentioned, I am able to get an actual token, so I'm pretty sure the problem is in how I've formed the request as opposed to not being properly authenticated. Keep in mind: This is being performed by a service account. Which means that it does have Read/Write access Thanks for reading, and I appreciate any help!

Developer’s Life – Every Developer is a Captain America

- by Pinal Dave

Captain America was first created as a comic book character in the 1940’s as a way to boost morale during World War II. Aimed at a children’s audience, his legacy faded away when the war ended. However, he has recently has a major reboot to become a popular movie character that deals with modern issues. When Captain America was first written, there was no such thing as a developer, programmer or a computer (the way we think of them, anyway). Despite these limitations, I think there are still a lot of ways that modern Captain America is like modern developers. So how are developers like Captain America? Well, read on my list of reasons. Take on Big Projects Captain America isn’t afraid to take on big projects – and takes responsibility when the project is co-opted by the evil organization HYDRA. Developers may not have super villains out there corrupting their work, but they know to keep on top of their projects and own what they do. Elderly Wisdom Steve Rogers, Captain America’s alter ego, was frozen in ice for decades, and brought back to life to solve problems. Developers can learn from this by respecting the opinions of their elders – technology is an ever-changing market, but the old-timers still have a few tricks up their sleeves! Don’t be Afraid of Change Don’t be afraid of change. Captain America woke up to find the world he was accustomed to is now completely different. He might have even felt his skills were no longer necessary. He, and developers, know that everyone has their place in a team, though. If you try your best, you will make it work. Fight Your Own Battle Sometimes you have to make it on your own. Captain America is an integral part of the Avengers, but in his own movies, the other superheroes aren’t around to back him up. Developers, too, must learn to work both within and with out a team. Solid Integrity One of Captain America’s greatest qualities is his integrity. His determine to do what is right, keep his word, and act honestly earns him mockery from some of the less-savory characters – even “good guys” like Iron Man. Developers, and everyone else, need to develop the strength of character to keep their integrity. No matter your walk of life, there will be tempting obstacles. Think of Captain America, and say “no.” There is a lot for all of us to learn from Captain America, to take away in our own lives, and admire in those who display it – I am specifically thinking of developers. If you are enjoying this series as much as I am, please let me know who else you would like to see featured.

Effectively implementing a game view using java

- by kdavis8

I am writing a 2d game in java. The game mechanics are similar to the Pokémon game boy advance series e.g. fire red, ruby, diamond and so on. I need a way to draw a huge map maybe 5000 by 5000 pixels and then load individual in game sprites to across the entirety of the map, like rendering a scene. Game sprites would be things like terrain objects, trees, rocks, bushes, also houses, castles, NPC's and so on. But i also need to implement some kind of camera view class that focuses on the player. the camera view class needs to follow the characters movements throughout the game map but it also needs to clip the rest of the map away from the user's field of view, so that the user can only see the arbitrary proximity adjacent to the player's sprite. The proximity's range could be something like 500 pixels in every direction around the player’s sprite. On top of this, i need to implement an independent resolution for the game world so that the game view will be uniform on all screen sizes and screen resolutions. I know that this does sound like a handful and may fall under the category of multiple questions, but the questions are all related and any advice would be very much appreciated. I don’t need a full source code listing but maybe some pointers to effective java API classes that could make doing what i need to do a lot simpler. Also any algorithmic/ design advice would greatly benefit me as well. example of what i am trying to do in source code form below package myPackage; /** * The Purpose of GameView is to: Render a scene using Scene class, Create a * clipping pane using CameraView class, and finally instantiate a coordinate * grid using Path class. * * Once all of these things have been done, GameView class should then be * instantiated and used jointly with its helper classes. CameraView should be * used as the main drawing image. CameraView is the the window to the game * world.Scene passes data constantly to CameraView so that the entire map flows * smoothly. Path uses the x and y coordinates from camera view to construct * cells for path finding algorithms. */ public class GameView { // Scene is a helper class to game view. it renders the entire map to memory // for the camera view. Scene scene; // Camera View is a helper class to game view. It clips the Scene into a // small image that follows the players coordinates. CameraView Camera; // Path is a helper class to game view. It observes and calculates the // coordinates of camera view and divides them into Grids/Cells for Path // finding. Path path; // this represents the player and has a getSprite() method that will return // the current frame column row combination of the passed sprite sheet. Sprite player; }

Easy Listening = CRM On Demand Podcasts

- by Anne

OK, here's my NEW favorite resource for CRM On Demand info -- podcasts! Specifically, the CRM On Demand Podcast site -- signed, sealed, and delivered with humor and know-how. Yes, I admit, I know the cast of characters. But let's face it, sometimes dealing with software is just soooo dry! Not so when discussed by the two main commentators, Louis Peters and Robert Davidson, whom someone once referred to as CRM On Demand's "Click and Clack." (Thought that was too good not to pass along!) Anyhow, another huge plus about the site is the option to listen OR to read. Out walking my dog or doing the dishes? Just turn up the podcast. Listening to music or watching TV? I'll read Louis's entertaining write-ups to glean great info about CRM On Demand in a very short period of time. So that you get a better understanding of why I like this site so much, here's a sampling of what's discussed: Five Things about Books of Business As Louis Peters put it in his entry, when you see "Five Things" in the title, "you'll know you're going to get some concrete advice that you can put to work right away." Well, Louis and Robert do just that, pointing you in the right direction when using Books of Business to segment data. Moving to Indexed Fields - A Rough Guide (only an article, not a podcast) I've read all about performance and even helped develop material around it. But nowhere have I heard indexed custom fields referred to as "super heroes." Louis and Robert use imaginative language to describe the process for moving your data to indexed fields for optimal performance. Data Access QA from the Forums I think that everyone would admit that data access and visibility is the most difficult topic to understand in CRM On Demand. Following up on their previous podcast on the same topic, Louis and Robert answer a few key questions from the many postings on the Oracle CRM On Demand forums. And I bet that the scenarios match many companies' business requirements...maybe even yours! We Need to Talk About Adoption Another expert, Tim Koehler, joins Louis to talk about how to drive user adoption: aligning product usage with business results, communicating why and how to use the product, getting feedback on usability, and so on. Hope I've made my point -- turn to these podcasts to hear knowledgeable folks discuss CRM On Demand tips and tricks in entertaining ways. One podcast is even called "SaaS Talk"!

SQLAuthority News – Social Media Series – Twitter and Myself

- by pinaldave

Pinal Dave on Twitter! Frequent readers of my blog might know that I am trying to get more involved in all social media sites, both professionally and personally. Readers might also know that I have often struggled with finding the purpose of some social media sites – Twitter especially. One of the great uses of social media is to stay connected and updated with followers. Twitter’s 140 character limit means that Twitter is a great place to get quick updates from the world, but not a lot of deep information. In fact, I have the feeling that Twitter’s form might actually limit its usefulness – especially for complex subjects like SQL Server. However, #sqlhelp has tag has for sure overcome that belief. You can instantly talk about SQL and get help with your SQL problems on twitter. I believe in keeping up with the changing times, and it didn’t feel right to give up on Twitter. So I have determined a good way to use Twitter and set rules for myself. The problem I was facing that if I followed everyone who interested me and let anyone follow me, I was completely overwhelmed by the amount of information Twitter could give me every day. It didn’t seem like 140 characters should be able to take up so much of my time, but it took hours to sort through all the updates to find things that were of interest to me and to SQL Server. First, I was forced to unfollow anyone who made too many updates every day. This was not an easy decision, but just for my own sake I had to limit the amount of information I could take in every day. I still let anyone follow me who wants to, because I didn’t want to limit my readership, and I hope that they do not feel the way I did – that there are too many updates! Next, I made sure that the information I put on Twitter is useful and to the point. I try to announce new blog posts on Twitter at least once a day, and I also try to find five posts from other people every day that are worth re-Tweeting. This forces me to stay active in the community. But it is not all business on Twitter. It is also a place for me to post updates about my family and home life, for anyone who is interested. In simple words, I talk every thing and anything on twitter. If you’d like to follow me, my Twitter handle is www.twitter.com/pinaldave. It is a good place to start if you’d like to keep updated with my blog and find out who I follow and who my influences are. Twitter is perfect for getting little “tastes” of things you’re interested in. If you are interested in my blog, SQL Server, or both, I hope that my Twitter updates will be interesting and helpful.

Programming doesn’t have to be Magic

- by Wes McClure

In the show LOST, the Swan Station had a button that “had to be pushed” every 100 minutes to avoid disaster. Several characters in the show took it upon themselves to have faith and religiously push the button, resetting the clock and averting the unknown “disaster”. There are striking similarities in this story to the code we write every day. Here are some common ones that I encounter: “I don’t know what it does but the application doesn’t work without it” “I added that code because I saw it in other similar places, I didn’t understand it, but thought it was necessary.” (for consistency, or to make things “work”) “An error message recommended it” “I copied that code” (and didn’t look at what it was doing) “It was suggested in a forum online and it fixed my problem so I left it” In all of these cases we haven’t done our due diligence to understand what the code we are writing is actually doing. In the rush to get things done it seems like we’re willing to push any button (add any line of code) just to get our desired result and move on. All of the above explanations are common things we encounter, and are valid ways to work through a problem we have, but when we find a solution to a task we are working on (whether a bug or a feature), we should take a moment to reflect on what we don’t understand. Remove what isn’t necessary, comprehend and simplify what is. Why is it detrimental to commit code we don’t understand? Perpetuates unnecessary code If you copy code that isn’t necessary, someone else is more likely to do so, especially peers Perpetuates tech debt Adding unnecessary code leads to extra code that must be understood, maintained and eventually cleaned up in longer lived projects Tech debt begets tech debt as other developers copy or use this code as guidelines in similar situations Increases maintenance How do we know the code is simplified if we don’t understand it? Perpetuates a lack of ownership Makes it seem ok to commit anything so long as it “gets the job done” Perpetuates the notion that programming is magic If we don’t take the time to understand every line of code we add, then we are contributing to the notion that it is simply enough to make the code work, regardless of how. TLDR Don’t commit code that you don’t understand, take the time to understand it, simplify it and then commit it!

New regular expression features in PCRE 8.34 and 8.35

- by Jan Goyvaerts

PCRE 8.34 adds some new regex features and changes the behavior of a few to make it better compatible with the latest versions of Perl. There are no changes to the regex syntax in PCRE 8.35. \o{377} is now an octal escape just like \377. This syntax was first introduced in Perl 5.12. It avoids any confusion between octal escapes and backreferences. It also allows octal numbers beyond 377 to be used. E.g. \o{400} is the same as \x{100}. If you have any reason to use octal escapes instead of hexadecimal escapes then you should definitely use the new syntax. Because of this change, \o is now an error when it doesn’t form a valid octal escape. Previously \o was a literal o and \o{377} was a sequence of 337 o‘s. In free-spacing mode, whitespace between a quantifier and the ? that makes it lazy or the + that makes it possessive is now ignored. In Perl this has always been the case. In PCRE 8.33 and prior, whitespace ended a quantifier and any following ? or + was seen as a second quantifier and thus an error. The shorthand \s now matches the vertical tab character in addition to the other whitespace characters it previously matched. Perl 5.18 made the same change. Many other regex flavors have always included the vertical tab in \s, just like POSIX has always included it in [[:space:]]. Names of capturing groups are no longer allowed to start with a digit. This has always been the case in Perl since named groups were added to Perl 5.10. PCRE 8.33 and prior even allowed group names to consist entirely of digits. [[:<:]] and [[::]] are now treated as POSIX-style word boundaries. They match at the start and the end of a word. Though they use similar syntax, these have nothing to do with POSIX character classes and cannot be used inside character classes. Perl does not support POSIX word boundaries. The same changes affect PHP 5.5.10 (and later) and R 3.0.3 (and later) as they have been updated to use PCRE 8.34. RegexBuddy and RegexMagic have been updated to support the latest versions of PCRE, PHP, and R. Older versions that were previously supported are still supported, so you can compare or convert your regular expressions between the latest versions of PCRE, PHP, and R and whichever version you were using previously.

Text Trimming in Silverlight 4

- by dwahlin

Silverlight 4 has a lot of great features that can be used to build consumer and Line of Business (LOB) applications. Although Webcam support, RichTextBox, MEF, WebBrowser and other new features are pretty exciting, I’m actually enjoying some of the more simple features that have been added such as text trimming, built-in wheel scrolling with ScrollViewer and data binding enhancements such as StringFormat. In this post I’ll give a quick introduction to a simple yet productive feature called text trimming and show how it eliminates a lot of code compared to Silverlight 3. The TextBlock control contains a new property in Silverlight 4 called TextTrimming that can be used to add an ellipsis (…) to text that doesn’t fit into a specific area on the user interface. Before the TextTrimming property was available I used a value converter to trim text which meant passing in a specific number of characters that I wanted to show by using a parameter: public class StringTruncateConverter : IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { int maxLength; if (int.TryParse(parameter.ToString(), out maxLength)) { string val = (value == null) ? null : value.ToString(); if (val != null && val.Length > maxLength) { return val.Substring(0, maxLength) + ".."; } } return value; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } #endregion } To use the StringTruncateConverter I'd define the standard xmlns prefix that referenced the namespace and assembly, add the class into the application’s Resources section and then use the class while data binding as shown next: <TextBlock Grid.Column="1" Grid.Row="3" ToolTipService.ToolTip="{Binding ReportSummary.ProjectManagers}" Text="{Binding ReportSummary.ProjectManagers, Converter={StaticResource StringTruncateConverter},ConverterParameter=16}" Style="{StaticResource SummaryValueStyle}" /> With Silverlight 4 I can define the TextTrimming property directly in XAML or use the new Property window in Visual Studio 2010 to set it to a value of WordEllipsis (the default value is None): <TextBlock Grid.Column="1" Grid.Row="4" ToolTipService.ToolTip="{Binding ReportSummary.ProjectCoordinators}" Text="{Binding ReportSummary.ProjectCoordinators}" TextTrimming="WordEllipsis" Style="{StaticResource SummaryValueStyle}"/> The end result is a nice trimming of the text that doesn’t fit into the target area as shown with the Coordinator and Foremen sections below. My data binding statements are now much smaller and I can eliminate the StringTruncateConverter class completely.

PeopleSoft HCM @ OHUG 11: Enter the Matrix

- by Jay Zuckert

The PeopleSoft HCM team is back from a very busy and exciting OHUG conference in Orlando. The packed, standing-room only PeopleSoft HCM Roadmap keynote was the highlight of the conference for many attendees and the reviews are in : PeopleSoft rocked the house ! Great demonstration of products in the keynote. Best keynote in a long time, and fun. Engaging and entertaining, great demonstration of capabilities. Message received loud and clear, PeopleSoft applications are here to stay. PeopleSoft has a real vision moving forward. Real-time polls using mobile texting were cutting edge. Tracy Martin (as Trinity) and other members of the PeopleSoft HCM team presented a ‘must-see’ Matrix-themed session while dressed as movie characters. The keynote highlighted planned HCM capabilities for Matrix administration and future organization visualization enhancements. The team also previewed the planned Manager Dashboard and Talent Summary. Following the keynote, some of the cast posed for photo opportunities at the OHUG booth in the exhibition hall. As you can imagine, they received some interesting looks walking by the other vendor booths. The PeopleSoft HCM team also presented numerous other OHUG sessions covering PeopleSoft Talent Management, Compensation, HR HelpDesk, Payroll, Global HCM Practices, Time & Labor, Absence Management, and Benefits. All of those presentations are available from the OHUG site at www.ohug.org. When not in one of the well-attended PeopleSoft HCM sessions, conference attendees filled the Oracle booth in the exhibition hall to see live product demonstrations. True to their PeopleSoft roots, some of the PeopleSoft HCM team played as hard as they worked in Orlando and enjoyed the OHUG Appreciation event along with customers at the Hard Rock. We are already busy planning for Oracle OpenWorld 2011 and prepping sessions our PeopleSoft HCM customers are sure to like. We hope to see you there in San Francisco from Oct. 2-6.

Windows CE: Changing Static IP Address

- by Bruce Eitman

A customer contacted me recently and asked me how to change a static IP address at runtime. Of course this is not something that I know how to do, but with a little bit of research I figure out how to do it. It turns out that the challenge is to request that the adapter update itself with the new IP Address. Otherwise, the change in IP address is a matter of changing the address in the registry for the adapter. The registry entry is something like: [HKEY_LOCAL_MACHINE\Comm\LAN90001\Parms\TcpIp] "EnableDHCP"=dword:0 "IpAddress"="192.168.0.100" "DefaultGateway"="192.168.0.1" "Subnetmask"="255.255.255.0" Where LAN90001 would be replace with your adapter name. I have written quite a few articles about how to modify the registry, including a registry editor that you could use. Requesting that the adapter update itself is a matter of getting a handle to the NDIS driver, and then asking it to refresh the adapter. The code is: #include <windows.h> #include "winioctl.h" #include "ntddndis.h" void RebindAdapter( TCHAR *adaptername ) { HANDLE hNdis; BOOL fResult = FALSE; int count; // Make this function easier to use - hide the need to have two null characters. int length = wcslen(adaptername); int AdapterSize = (length + 2) * sizeof( TCHAR ); TCHAR *Adapter = malloc(AdapterSize); wcscpy( Adapter, adaptername ); Adapter[ length ] = '\0'; Adapter[ length +1 ] = '\0'; hNdis = CreateFile(DD_NDIS_DEVICE_NAME, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_ALWAYS, 0, NULL); if (INVALID_HANDLE_VALUE != hNdis) { fResult = DeviceIoControl(hNdis, IOCTL_NDIS_REBIND_ADAPTER, Adapter, AdapterSize, NULL, 0, &count, NULL); if( !fResult ) { RETAILMSG( 1, (TEXT("DeviceIoControl failed %d\n"), GetLastError() )); } CloseHandle(hNdis); } else { RETAILMSG( 1, (TEXT("Failed to open NDIS Handle\n"))); } } int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPWSTR lpCmdLine, int nCmdShow) { RebindAdapter( TEXT("LAN90001") ); return 0; } If you don’t want to write any code, but instead plan to use a registry editor to change the IP Address, then there is a command line utility to do the same thing. NDISConfig.exe can be used: Ndisconfig adapter rebind LAN90001 Copyright © 2012 – Bruce Eitman All Rights Reserved

View HTML Tags and Webpage Combined in Firefox

- by Asian Angel

Do you want an easier way to see a webpage’s html tags without viewing the source code in a separate window? Now you can view the webpage and tags combined in the same window using the X-Ray extension for Firefox. Before Usually if you want to see the source code behind a webpage you have to view it in a separate window. If you are only interested in a specific section then you have to search through the entire set of code just to find what you are looking for. After The X-Ray extension will let you see the document’s tags (including class and ID names) “side by side” with the webpage in the same tab. You can use either the context menu or the tools menu to access the X-Ray command. Here is the same webpage section shown in the first screenshot above. It may look a little odd at first until you get used to seeing both together. Note: You can return the webpage to its’ normal view by either clicking on the X-Ray command again or refreshing the page. The code for part of the sidebar on the same webpage… Followed by one of the sets of links at the end. Looking at another example suppose you are interested in how part of the main feed is set up. Being able to see how a particular element is set up directly in the webpage is certainly better than searching through the entire page of code. Conclusion If you design webpages and want an easy way to see how someone else’s website is coded then you may want to give this extension a try.
