  • WPF 3D - converting from Point2D to Point3D and back again

    - by DanM
    I'm new to WPF 3D, so I may just be missing something obvious, but how would I go about converting from a 2D coordinate to a 3D coordinate and back again? I'd like the 2D coordinate to be the location measured from the upper-left corner of Viewport3D and the 3D coordinate to be the location relative to the origin (0, 0, 0) of the 3D world. The conversion functions should have these signatures: public Point3D Point2DAndWorldZToPoint3D(Point2D point2D, double worldZ) // usually I want to know where a 2D point will be on the ground plane // so worldZ will usually be zero (but not always) public Point2D Point3DToPoint2D(Point3D point3D) I found this related question, but it only addresses conversion from 3D to 2D (not the reverse), and I'm not sure if the answers are up-to-date. Note, I'm currently using .NET 3.5, but if there are improvements in .NET 4.0 that would help me, please let me know.

  • jQuery Smooth Sliding DIV Height

    - by Stu
    I have a Div that is 400px in height with the ID "content", I then do a slideToggle on the Div, load some data into the Div of a varying height e.g. 200px, and then do another slideToggle. What I get is the slide expanding to 400px, then jump back to 200px. And the same in reverse, expanding to 200px, then jump to 400px. This is my code: $('#content').slideToggle(600, function() { $("#content").load('data.php').slideToggle(600); }); So I thought I could do something like this, which would slide up the content Div, load the data, and then after it's loaded slide back down. This doesn't jump like the above method, but it is quite jerky for some reason. $('#content').slideUp(600, function() { $("#content").load('data.php', function() { $("#content").slideDown(600); }); }); Can anybody tell me if there is a better way of doing this so that I can slide it smoothly?

  • Is there a good way to convert between BitmapSource and Bitmap?

    - by JohannesH
    As far as I can tell the only way to convert from BitmapSource to Bitmap is through unsafe code... Like this (from Lesters WPF blog): myBitmapSource.CopyPixels(bits, stride, 0); unsafe { fixed (byte* pBits = bits) { IntPtr ptr = new IntPtr(pBits); System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap( width, height, stride, System.Drawing.Imaging.PixelFormat.Format32bppPArgb,ptr); return bitmap; } } To do the reverse: System.Windows.Media.Imaging.BitmapSource bitmapSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap( bitmap.GetHbitmap(), IntPtr.Zero, Int32Rect.Empty, System.Windows.Media.Imaging.BitmapSizeOptions.FromEmptyOptions()); Is there an easier way in the framework? And what is the reason it isn't in there (if it's not)? I would think it's fairly usable. The reason I need it is because I use AForge to do certain image operations in an WPF app. WPF wants to show BitmapSource/ImageSource but AForge works on Bitmaps.

  • How to convert DATETIME to FILETIME value in T-SQL?

    - by Alek Davis
    I need to convert a SQL Server DATETIME value to FILETIME in a T-SQL SELECT statement (on SQL Server 2000). Is there a built-in function to do this? If not, can someone help me figure out how to implement this conversion routine as a UDF (or just plain Transact-SQL)? Here is what I know: FILETIME is 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601 (UTC) (per MSDN: FILETIME Structure). SQL Server time era starts on 1900-01-01 00:00:00 (per SELECT CAST(0 as DATETIME). I found several examples showing how to convert FILETIME values to T-SQL DATETIME (I'm not 100% sure they are accurate, though), but could not find anything about reverse conversion. Even the general idea (or algorithm) would help.

  • WPF 3D - Need help writing conversion methods between 2D and 3D (Point3DToPoint and PointAndZToPoint

    - by DanM
    I'm new to WPF 3D, so I may just be missing something obvious, but how do I convert from 3D to 2D and (for a given z location) from 2D to 3D? Specifically, I need two conversion methods: Point3DToPoint - If I have an (x, y, z) coordinate in the 3D world, how do I determine the (x, y) coordinate on the projected 2D surface. Method signature: public Point Point3DToPoint(Point3D point3D) PointAndZToPoint3D - If I have an (x, y) coordinate on the projected 2D surface and a z location in the 3D world, how do I determine the intersecting (x, y, z) coordinate in the 3D world? Method signature: public Point3D PointAndZToPoint3D(Point point, double z) I'd like the 2D coordinate to be the location measured from the upper-left corner of Viewport3D and the 3D coordinate to be the location relative to the origin (0, 0, 0) of the 3D world. Note 1: I found this related question, but it only addresses conversion from 3D to 2D (not the reverse), and I'm not sure if the answers are up-to-date. Note 2: I'm currently using .NET 3.5, but if there are improvements in .NET 4.0 that would help me, please let me know.

  • Problems configuring nameserver in plesk

    - by Saif Bechan
    Hello, i have some troubles with setting up a nameserver in PLESK for months now. I have tried all possible scenario's but i can not get this to work. I am really in need for some help, and if you can i will really appreciate it. Basically what i want is to just set up a nameserver in PLESK. I have a primary IP, and my host gave me a secondary nameserver i can use. My host is leaseweb in the netherlands. I have made some screenshots of the important parts in my opinion, maybe you guys can see some errors in them. To use the secondary nameserver provided by leaseweb i had to enable ACL on that account, i did so and made a screenshot of that too. The DNS recursion is set to localnets. These settings have not changed for months, so the dns should be fully updated everywhere. The check i run is the following: https://www.sidn.nl/over-nl/aanvraag...-server-check/ Domeinnaam (inclusief .nl): rdshosting.nl Eerste Nameserver: ns1.rdshosting.nl Eerste IP: 62.212.66.33 Tweede Nameserver: ns7.leaseweb.net Tweede ip: 62.212.76.50 If i run the dns check of the netherlands it gives me the following errors: primary name server "ns1.rdshosting.nl." Error: specified name server is not listed as NS record. All public name servers for a domain must also be listed as NS records in the zone of the domain. This domain was specified explicitly as a name server, but not found in the zone description of the primary name server. TE.6a rdshosting.nl. 86400 IN SOA ns1.rdspartners.nl. saif2k.hotmail.com.

Warning: hidden name server "ns1.rdspartners.nl." never used for first contact. The zone contains an NS record for a host which is not in the list of specified name servers. Hence, this name server will not be used to initiate contact to the domain. It may be used in sequential lookups, so it may still be useful. secondary name server "ns1.rdspartners.nl."

  • Create Text File Without BOM

    - by balexandre
    Hi guys, I tried this aproach without any success the code I'm using: // File name String filename = String.Format("{0:ddMMyyHHmm}", dtFileCreated); String filePath = Path.Combine(Server.MapPath("App_Data"), filename + ".txt"); // Process ProcessPBS pbs = new ProcessPBS(); pbs.CreatePBSInfoFile(pbslist, Convert.ToInt64(filename)); // Save file Encoding utf8WithoutBom = new UTF8Encoding(true); TextWriter tw = new StreamWriter(filePath, false, utf8WithoutBom); foreach (string s in pbs.GeneratedFile.ToArray()) tw.WriteLine(s); tw.Close(); // Push Generated File into Client Response.Clear(); Response.ContentType = "application/vnd.text"; Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + ".txt"); Response.TransmitFile(filePath); Response.End(); the result: It's writing the BOM no matter what, and special chars (like Æ Ø Å) are not correct :-/ I'm stuck! I can't create a file using UTF-8 as Encoding and 8859-1 as CharSet :-( Anyone can help me find the light in the tunnel? All help is greatly appreciated, thank you!

  • Putting data from local SQL database to remote SQL database without remote SQL access enabled (PHP)

    - by Shyam
    Hi, I have a local database, and all the tables are defined. Eventually I need to publish my data remotely, which I can do easily with PHPmyadmin. Problem however is that my remote host doesn't allow remote SQL connections at all, so writing a script that does a mysqldump and run it through a client (which would've been ideal) won't help me here. Since the schema won't change, but the data will, I need some kind of PHP client that works "reverse". My question is if such a client exists and what would be recommended to use (by experience). I just need an one way trip here, from my local database (Rails) to the remote database (supports PHP), preferable as simple and slick as possible. Thank you for your replies, comments and feedback!

  • ssh tunneling with visualsvn

    - by DeveloperChris
    I have been asked to setup visualsvn for visual studio 2008 Due to firewall restrictions and server configuration. I need to use ssh tunneling. My problem is this. The local machine needs to connect to a gateway machine via ssh then connect to the subversion server so Local machine ---{ssh}--- gateway ---{ssh}-- subversion server I am not exactly sure of the correct process to do this. It appears that I must start a ssh process using plink to open a local port and forward that to the remote subversion server. eg: plink user@gateway -L 22:192.168.1.1:22 Then when visualsvn starts it uses tortoiseplink to make the actual connection through to the subversion server using svn+ssh://username@localhost:22/myrepo This seems very very clunky. firstly it needs several steps to setup the connection secondly I need plink running which leaves a command prompt on the desktop (clutter = yuck) lastly I need to use two different programs that do the same thing. (plink + tortoiseplink) The problem is that tortoiseplink doesn't run in the background. As soon as I connect to the ssh gateway and enter the password it closes again. So I can't use it to create the initial connection. If I use plink instead of tortoiseplink in visualsvn then I never get prompted for the password. so it just hangs with an open command prompt and no password request. Is there a way to setup visualsvn so that everything happens in one command line? I have searched high and low for a suitable and clean method to tunnel from visualsvn to the remote server and have found very little. it all either assumes one hop (not two like mine) or it glosses over all the hard bits.

  • PHP postgres backup.

    - by russell kinch
    Hi. I am trying to make a Postgres PHP backup script. I have downloaded one for the command line which looks like this: #!/bin/bash find /home/russell/pg_bkp -type f -mtime +7 -exec rm {} \; time=`date +%Y-%m-%d`; # date in reverse so that lastest date appears last in the list of backup files. PGPASSWORD=****** pg_dump -i -h localhost -p 5432 -U postgres -F c -b -v -f "/home/russell/pg_bkp/$time.backup" ah3 How can I implement this in PHP? The extension that this creates is .backup. It works great and have used it many times. the data is perfect, but doing it from inside my website would be better. Thanks

  • Best Geocoding Service for iPhone Developers

    I have made an app that gets an array of addresses from a web service and I want to map them. I know Apple left this out in MapKit, including only a reverse GeoCoder. I was wondering what the best way to approach this problem was. Web Service? Google Maps API (How do API keys work?)? CloudMade? What is your opinions on which service is fastest, easiest to use, and cheapest (hopefully free)? Thanks, Conrad Kramer

  • Tracking Google Analytics events with server side request automation

    - by Esko
    I'm currently in the process of programming an utility which generates GA tracking pixel (utm.gif) URL:s based on given parameters. For those of you who are wondering why I'm doing this on the server side, I need to do this server side since the context which I'm going to start tracking simply doesn't support JavaScript and as such ga.js is completely useless to me. I have managed to get it working otherwise quite nicely but I've hit a snag: I can't track events or custom variables because I have no idea how exactly the utme parameter's value should be structured to form a valid event or var type hit. GA's own documentation on this parameter isn't exactly that great, either. I've tried everything from Googling without finding anything (which I find ironic) to reverse engineering ga.js, unfortunately it's minified and quite unreadable because of that. The "mobile" version of GA didn't help either since officially GA mobile doesn't support events nor vars. To summarize, what is the format of the utme parameter for page hit types event and custom variable?

  • Eclipse: Synchronizing project on Thumbdrive with PC

    - by Thomas Matthews
    I have a thumb drive (memory stick, flash drive, etc.) on which I use for my projects when I am away from my home PC. Currently I am accessing my Eclipse project directly from my thumb drive when connected to my PC. I would like to copy my files to the PC, develop on the PC, then "synchronize" with the thumb drive (update files on the thumb drive). I also need the reverse process too: synchronize thumb drive files with files on PC. I have looked at the FileSync plugin, but it specifically says it is one-way. How can I synchronize my Eclipse project both directions (PC to thumb drive and thumb drive to PC) on demand (I don't need this done automagically)?

  • Yahoo flagging mail as spam when using relay server

    - by modulaaron
    I'm using Postfix to relay mail from my site to my mail server. Mail is received properly at my Gmail and Hotmail accounts - only Yahoo is the problem. The Yahoo mail headers state: Received-SPF: none (mta1133.mail.mud.yahoo.com: domain of [email protected] does not designate permitted sender hosts) In contrast, the Gmail headers state: Received-SPF: pass (google.com: domain of [email protected] designates 74.50.xxx.xxx as permitted sender) client-ip=74.50.xxx.xxx; Reverse DNS is set up correctly, as is my SPF record. Does anyone have any suggestions as to what I can do to solve the Yahoo problem (short of contacting Yahoo, as this is a brand new mail server)? FYI - I just set up domainkeys, but I'm not sure whether they should be on the origin or relay server. Thanks

  • Code Golf: Triforce

    - by chpwn
    This is inspired by/taken from this thread: http://www.allegro.cc/forums/thread/603383 The Problem Assume the user gives you a numeric input ranging from 1 to 7. Input should be taken from the console, arguments are less desirable. When the input is 1, print the following: *********** ********* ******* ***** *** * Values greater than one should generate multiples of the pattern, ending with the one above, but stacked symmetrically. For example, 3 should print the following: *********** *********** *********** ********* ********* ********* ******* ******* ******* ***** ***** ***** *** *** *** * * * *********** *********** ********* ********* ******* ******* ***** ***** *** *** * * *********** ********* ******* ***** *** * Bonus points if you print the reverse as well. *********** *********** ********* ********* ******* ******* ***** ***** *** *** * * *********** ********* ******* ***** *** * * *** ***** ******* ********* *********** * * *** *** ***** ***** ******* ******* ********* ********* *********** *********** Can we try and keep it to one answer per language, that we all improve on?

  • Jquery UI Slider - Input a Value and Slider Move to Location

    - by RobertC
    I was wondering if anyone has found a solution or example to actually populating the input box of a slider and having it slide to the appropriate position onBlur() .. Currently, as we all know, it just updates this value with the position you are at. So in some regards, I am trying to reverse the functionality of this amazing slider. One link I found: http://www.webdeveloper.com/forum/archive/index.php/t-177578.html is a bit outdated, but looks like they made an attempt. However, the links to the results do not exist. I am hoping that there may be a solution out there. I know Filament has re-engineered the slider to handle select (drop down) values, and it works flawlessly.. So the goal would be to do the same, but with an input text box. Any help would be incredible! Thanks in Advance!! Robert

  • Django URL resolving infrastructure stops working

    - by btol45
    We recently launched a new Django-powered website, and we are experiencing the oddest bug: The site is running under Apache with mod_fastcgi. Everything works fine for a while, and then the URL tag and reverse() functionality stops working. Instead of returning the expected URL, they return "". We haven't noticed anything in Apache's log file; there are no errors being generated by Django. And (the kicker) the problem only occurs in production mode; we can't reproduce it when DEBUG=True. Any thoughts on where we should be looking for the problem?

  • NUnit-console 2.5.4 not capable of running multiple assemblies?

    I am having problems running tests with the command line NUnit test runner. I am using version 2.5.4 with .NET 4 on an x64 machine. Using the following line results in a failure "Could not load file or assembly 'bar' or one of its dependencies. The system cannot find the file specified." nunit-console-x86 foo.dll bar.dll /framework=4.0.30319 If I reverse the dll file names it complains about not finding 'foo' instead...

It seems like the ability to run tests on multiple files at the same time is broken... Anyone that can see the same behavior or does it work indicating that my environment is somehow broken? /Per

  • Refactoring a custom User model to user UserProfile: Should I create a custom UserManager or add use

    - by BryanWheelock
    I have been refactoring an app that had customized the standard User model from django.contrib.auth.models by creating a UserProfile and defining it with AUTH_PROFILE_MODULE. The problem is the attributes in UserProfile are used throughout the project to determine the User sees. I had been creating tests and putting in this type of statement repeatedly: user = User.objects.get(pk=1) user_profile = user.get_profile() if user_profile.karma > 10: do_some_stuff() This is tedious and I'm now wondering if I'm violating the DRY principle. Would it make more sense to create a custom UserManager that automatically loads the UserProfile data when the user is requested. I could even iterate over the UserProfile attributes and append them to the User model. This would save me having to update all the references to the custom model attributes that litter the code. Of course, I'd have to reverse to process for to allow the User and UserProfile models to be updated correctly. Which approach is more Django-esque?

  • Nested dereferencing arrows in Perl: to omit or not to omit?

    - by DVK
    In Perl, when you have a nested data structure, it is permissible to omit de-referencing arrows to 2d and more level of nesting. In other words, the following two syntaxes are identical: my $hash_ref = { 1 => [ 11, 12, 13 ], 3 => [31, 32] }; my $elem1 = $hash_ref->{1}->[1]; my $elem2 = $hash_ref->{1}[1]; # exactly the same as above Now, my question is, is there a good reason to choose one style over the other? It seems to be a popular bone of stylistic contention (Just on SO, I accidentally bumped into this and this in the space of 5 minutes). So far, none of the usual suspects says anything definitive: perldoc merely says "you are free to omit the pointer dereferencing arrow". Conway's "Perl Best Practices" says "whenever possible, dereference with arrows", but it appears to only apply to the context of dereferencing the main reference, not optional arrows on 2d level of nested data structures. "MAstering Perl for Bioinfirmatics" author James Tisdall doesn't give very solid preference either: "The sharp-witted reader may have noticed that we seem to be omitting arrow operators between array subscripts. (After all, these are anonymous arrays of anonymous arrays of anonymous arrays, etc., so shouldn't they be written [$array-[$i]-[$j]-[$k]?) Perl allows this; only the arrow operator between the variable name and the first array subscript is required. It make things easier on the eyes and helps avoid carpal tunnel syndrome. On the other hand, you may prefer to keep the dereferencing arrows in place, to make it clear you are dealing with references. Your choice." Personally, i'm on the side of "always put arrows in, since itg's more readable and obvious tiy're dealing with a reference".

  • Combinatorics, probability, dice

    - by TarGz
    A friend of mine asked: if I have two dice and I throw both of them, what is the most frequent sum (of the two dice' numbers)? I wrote a small script: from random import randrange d = dict((i, 0) for i in range(2, 13)) for i in xrange(100000): d[randrange(1, 7) + randrange(1, 7)] += 1 print d Which prints: 2: 2770, 3: 5547, 4: 8379, 5: 10972, 6: 13911, 7: 16610, 8: 14010, 9: 11138, 10: 8372, 11: 5545, 12: 2746 The question I have, why is 11 more frequent than 12? In both cases there is only one way (or two, if you count reverse too) how to get such sum (5 + 6, 6 + 6), so I expected the same probability..?

Post away and let's build a nice ~/.gitconfig [user] name = Rajkumar email = [email protected] [color] diff = auto status = auto branch = auto interactive = auto ui = true pager = true [color "branch"] current = yellow reverse local = yellow remote = green [color "diff"] meta = yellow bold frag = magenta bold old = red bold new = green bold [color "status"] added = yellow changed = green untracked = cyan [core] pager = less -FRSX whitespace=fix,-indent-with-non-tab,trailing-space,cr-at-eol [alias] co = checkout Thanks! raj

  • Creating an MJPEG Viewer Iphone

    - by Tony
    Hey all, Im trying to make a MJPEG viewer in Objective C but I'm having a bunch of issues with it. First off, Im using AsyncSocket(http://code.google.com/p/cocoaasyncsocket/) which lets me connect to the host. Here's what I got so far NSLog(@"Ready"); asyncSocket = [[AsyncSocket alloc] initWithDelegate:self]; //http://kamera5.vfp.slu.se/axis-cgi/mjpg/video.cgi NSError *err = nil; if(![asyncSocket connectToHost:@"kamera5.vfp.slu.se" onPort:80 error:&err]) { NSLog(@"Error: %@", err); } then in the didConnectToHost method: - (void)onSocket:(AsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port{ NSLog(@"Accepted client %@:%hu", host, port); NSString *urlString = [NSString stringWithFormat:@"http://kamera5.vfp.slu.se/axis-cgi/mjpg/video.cgi"]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"GET"]; //set headers NSString *_host = [NSString stringWithFormat:host]; [request addValue:_host forHTTPHeaderField: @"Host"]; NSString *KeepAlive = [NSString stringWithFormat:@"300"]; [request addValue:KeepAlive forHTTPHeaderField: @"Keep-Alive"]; NSString *connection = [NSString stringWithFormat:@"keep-alive"]; [request addValue:connection forHTTPHeaderField: @"Connection"]; //get response NSHTTPURLResponse* urlResponse = nil; NSError *error = [[NSError alloc] init]; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; NSLog(@"Response Code: %d", [urlResponse statusCode]); if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300) { NSLog(@"Response: %@", result); //here you get the response } } This calls the MJPEG stream, but it doesn't call it to get more data. What I think its doing is just loading the first chunk of data, then disconnecting. Am I doing this totally wrong or is there light at the end of this tunnel? Thanks!
