  • Create pdf file with ghostscript

    - by kofucii
    Hello, I'm using SCO Unix, with old version of ghostscript (7.7). When I convert the postscript source file to pdf otput file, It's content is visible on the SCO machine. But when I copy the pdf file into windows, and open it with adobe acrobat, all I can see is a blank page. Does anybody have a solution to this?

  • Converting a WPFToolkit DataGrid from 1D list to 2D matrix

    - by user61073
    Hello - I am wondering if anyone has attempted the following or has an idea as to how to do it. I have a WPFToolkit DataGrid which is bound to an ObservableCollection of items. As such, the DataGrid is shown with as many rows in the ObservableCollection, and as many columns as I have defined in for the DataGrid. That all is good. What I now need is to provide another view of the same data, only, instead, the DataGrid is shown with as many cells in the ObservableCollection. So let's say, my ObservableCollection has 100 items in it. The original scenario showed the DataGrid with 100 rows and 1 column. In the modified scenario, I need to show it with 10 rows and 10 columns, where each cell shows the value that was in the original representation. In other words, I need to transform my 1D ObservableCollection to a 2D ObservableCollection and display it in the DataGrid. I know how to do that programmatically in the code behind, but can it be done in XAML? Let me simplify the problem a little, in case anybody can have a crack at this. The XAML below does the following: * Defines an XmlDataProvider just for dummy data * Creates a DataGrid with 10 columns o each column is a DataGridTemplateColumn using the same CellTemplate * The CellTemplate is a simple TextBlock bound to an XML element If you run the XAML below, you will find that the DataGrid ends up with 5 rows, one for each book, and 10 columns that have identical content (all showing the book titles). However, what I am trying to accomplish, albeit with a different data set, is that in this case, I would end up with one row, with each book title appearing in a single cell in row 1, occupying cells 0-4, and nothing in cells 5-9. Then, if I added more data and had 12 books in my XML data source, I would get row 1 completely filled (cells covering the first 10 titles) and row 2 would get the first 2 cells filled. Can my scenario be accomplished primarily in XAML, or should I resign myself to working in the code behind? Any guidance would greatly be appreciated.

  • How to resize QInputDialog, PyQt

    - by siege
    I am getting input with this here areaInput = QtGui.QInputDialog.getText(self, "Copy Area", "New Area Name:", 0) However I would like to make the dialog box larger, I've tried things such as QtGui.QInputDialog.resize(400, 400) However it says "the first argument must be a QWidget class" and I'm not quite sure what this means or how to fix it. Thanks.

  • Reorder cells in a UITableView without displaying a "delete" button

    - by iter
    I want to be able to reorder cells in a table, but not to delete or insert them. I want a picture like this: This image appears in Apple's Table View Programming Guige, but the code samples there produce a table with red "delete" buttons when the table goes into editing mode. I can set editingStyleForRowAtIndexPath to UITableViewCellEditingStyleNone and that makes the delete buttons go away, but the rows are still indented as if to make room for these buttons.

  • Reset VS2010 Project Templates?

    - by Jimbo Jones
    I installed Blend 4 RC recently but strangely it deleted some of my VS2010 projects templates, including the most important ones being Silverlight User Control and Silverlight Application. Does anybody know how to get back these templates or tell VS2010 to reset all templates? A bit frustrating, I'm having to create projects on my laptop then copy them to my desktop manually :(

  • C++ vs Matlab vs Python as a main language for Computer Vision Postgraduate

    - by Hough
    Hi all, Firstly, sorry for a somewhat long question but I think that many people are in the same situation as me and hopefully they can also gain some benefit from this. I'll be starting my PhD very soon which involve the fields of computer vision, pattern recognition and machine learning. Currently, I'm using opencv (2.1) C++ interface and I especially like its powerful Mat class and the overloaded operations available for matrix and image seamless operations and transformations. I've also tried (and implemented many small vision projects) using opencv python interface (new bindings; opencv 2.1) and I really enjoy python's ability to integrate opencv, numpy, scipy and matplotlib. But recently, I went back to opencv C++ interface because I felt that the official python new bindings were not stable enough and no overloaded operations are available for matrices and images, not to mention the lack of machine learning modules and slow speeds in certain operations. I've also used Matlab extensively in the past and although I've used mex files and other means to speed up the program, I just felt that Matlab's performance was inadequate for real-time vision tasks, be it for fast prototyping or not. When the project becomes larger and larger, many tasks have to be re-written in C and compiled into Mex files increasingly and Matlab becomes nothing more than a glue language. Here comes the sub-questions: For postgrad studies in these fields (machine learning, vision, pattern recognition), what is your main or ideal programming language for rapid prototyping of ideas and testing algorithms contained in papers? For postgrad studies, can you list down the pros and cons of using the following languages? C++ (with opencv + gsl + svmlib + other libraries) vs Matlab (with all its toolboxes) vs python (with the imcomplete opencv bindings + numpy + scipy + matplotlib). Are there computer vision PhD/postgrad students here who are using only C++ (with all its availabe libraries including opencv) without even needing to resort to Matlab or python? In other words, given the current existing computer vision or machine learning libraries, is C++ alone sufficient for fast prototyping of ideas? If you're currently using Java or C# for your postgrad work, can you list down the reasons why they should be used and how they compare to other languages in terms of available libraries? What is the de facto vision/machine learning programming language and its associated libraries used in your university research group? Thanks in advance.

  • Deployment of About.htm with ClickOnce

    - by Melody Friedenthal
    I have a Win app (VB.net 2005) with an About.htm page that comes up when the user presses F1, using a HelpProvider control. The application was deployed using ClickOnce technology. When I release a new version I have to manually copy the About.htm file from my development area to our LAN (specified by the HelpNamespace property of the HelpProvider control). Is there a way I can include this as part of the deployment? Thank you.

  • Making mercurial subrepositories behave like subversion externals

    - by Emily Dickinson
    Hi guys, The FAQ, and hginit.com have been really useful for helping me make the transition from svn to hg. However, when it comes to using Hg's subrepository feature in the manner of subversion's externals, I've tried everythign and cannot replicate the nice behavior of svn externals. Here's the simplest example of what I want to do: Init "lib" repository This repository is never to be used as a standalone; it's always included by main repositories, as a sub-repository. Init one or more including repositories To keep the example simple, I'll "init" a repository called "main" Have "main" include "lib" as a subrepository Importantly -- AND HERE'S WHAT I CAN'T GET TO WORK: When I modify a file inside of "main/lib", and I push the modification, then that change gets pushed to the "lib" repository -- NOT to a copy inside of "main". Command lines speak louder than words. I've tried so many variations on this theme, but here's the gist. If someone can reply, in command lines, I'll be forever grateful! 1. Init "lib" repository $ cd /home/moi/hgrepos ## Where I'm storing my hg repositories, on my main server $ hg init lib $ echo "foo" lib/lib.txt $ hg add lib $ hg ci -A -m "Init lib" lib 2. Init "main" repository, and include "lib" as a subrepos $ cd /home/moi/hgrepos $ hg init main $ echo "foo" main/main.txt $ hg add main $ cd main $ hg clone ../lib lib $ echo "lib=lib" .hgsub $ hg ci -A -m "Init main" . This all works fine, but when I make a clone of the "main" repository, and make local modifications to files in "main/lib", and push them, the changes get pushed to "main/lib", NOT to "lib". IN COMMAND-LINE-ESE, THIS IS THE PROBLEM: $ /home/moi/hg-test $ hg clone ssh://[email protected]/hgrepos/lib lib $ hg clone ssh://[email protected]/hgrepos/main main $ cd main $ echo foo lib/lib.txt $ hg st M lib.txt $ hg com -m "Modified lib.txt, from inside the main repos" lib.txt $ hg push pushing to ssh://[email protected]/hgrepos/main/lib That last line of output from hg shows the problem. It shows that I've made a modification to a COPY of a file in lib, NOT to a file in the lib repository. If this were working as I'd like it to work, the push would be to hgrepos/lib, NOT to hgrepos/main/lib. I.e., I would see: $ hg push pushing to ssh://[email protected]/hgrepos/lib IF YOU CAN ANSWER THIS IN TERMS OF COMMAND LINES RATHER THAN IN ENGLISH, I WILL BE ETERNALLY GRATEFUL! Thank you in advance! Emily in Portland

  • Textmate Ruby on Rails Highlighting

    - by yuval
    Hi, I have textmate 1.5.7 running on my leopard machine. When programming in rails, for some reason some key words do not get highlighted. For example: validates_presence_of, has_many, remote_form_for (form_for gets highlighted) etc... I tried switching themes and it did not help. I also tried upgrading to the most recent rails bundle from http://railsbundle.com/ but no cigar. Could someone please help? Thank you very much, Yuval

  • Unshelving in TFS: What does it mean?

    - by lividsquirrel
    Here's the part I get: When you shelve in TFS, it makes a server copy of the changes so they are not lost, but does not check them into the source code trunk/branch you are working on. Question: Under what circumstances would you use the "unshelve" feature? Does it mean it will remove the shelveset from the TFS server? Can you do a get from a shelveset? Or is it really just a diff description between the shelveset and the "real" source code?

  • Freemarker/Velocity - date manipulation

    - by Razor
    Hello, I have a fairly simple question about these 2 templating engines. I'm trying to make a future/paste date, a fixed time from now, e.g. 18 months ago, or tomorrow. I know that it is possible to do this with a java date object inside a velocity/freemarker template (something like $date.add(2,-18)), but I would like to do this with DateTool or freemarker core. This is something that I see as purely presentational (just think at the default dates you see in flight booking forms), so I can't see any reason why a templating engine shouldn't be able to do this. Is it possible though? If so, how?

  • When constructing a Bitmap with Bitmap.FromHbitmap(), how soon can the original bitmap handle be del

    - by GBegen
    From the documentation of Image.FromHbitmap() at http://msdn.microsoft.com/en-us/library/k061we7x%28VS.80%29.aspx : The FromHbitmap method makes a copy of the GDI bitmap; so you can release the incoming GDI bitmap using the GDIDeleteObject method immediately after creating the new Image. This pretty explicitly states that the bitmap handle can be immediately deleted with DeleteObject as soon as the Bitmap instance is created. Looking at the implementation of Image.FromHbitmap() with Reflector, however, shows that it is a pretty thin wrapper around the GDI+ function, GdipCreateBitmapFromHBITMAP(). There is pretty scant documentation on the GDI+ flat functions, but http://msdn.microsoft.com/en-us/library/ms533971%28VS.85%29.aspx says that GdipCreateBitmapFromHBITMAP() corresponds to the Bitmap::Bitmap() constructor that takes an HBITMAP and an HPALETTE as parameters. The documentation for this version of the Bitmap::Bitmap() constructor at http://msdn.microsoft.com/en-us/library/ms536314%28VS.85%29.aspx has this to say: You are responsible for deleting the GDI bitmap and the GDI palette. However, you should not delete the GDI bitmap or the GDI palette until after the GDI+ Bitmap::Bitmap object is deleted or goes out of scope. Do not pass to the GDI+ Bitmap::Bitmap constructor a GDI bitmap or a GDI palette that is currently (or was previously) selected into a device context. Furthermore, one can see the source code for the C++ portion of GDI+ in GdiPlusBitmap.h that the Bitmap::Bitmap() constructor in question is itself a wrapper for the GdipCreateBitmapFromHBITMAP() function from the flat API: inline Bitmap::Bitmap( IN HBITMAP hbm, IN HPALETTE hpal ) { GpBitmap *bitmap = NULL; lastResult = DllExports::GdipCreateBitmapFromHBITMAP(hbm, hpal, &bitmap); SetNativeImage(bitmap); } What I can't easily see is the implementation of GdipCreateBitmapFromHBITMAP() that is the core of this functionality, but the two remarks in the documentation seem to be contradictory. The .Net documentation says I can delete the bitmap handle immediately, and the GDI+ documentation says the bitmap handle must be kept until the wrapping object is deleted, but both are based on the same GDI+ function. Furthermore, the GDI+ documentation warns against using a source HBITMAP that is currently or previously selected into a device context. While I can understand why the bitmap should not be selected into a device context currently, I do not understand why there is a warning against using a bitmap that was previously selected into a device context. That would seem to prevent use of GDI+ bitmaps that had been created in memory using standard GDI. So, in summary: Does the original bitmap handle need to be kept around until the .Net Bitmap object is disposed? Does the GDI+ function, GdipCreateBitmapFromHBITMAP(), make a copy of the source bitmap or merely hold onto the handle to the original? Why should I not use an HBITMAP that was previously selected into a device context?

  • complete, monospaced Unicode font?

    - by nachik
    I'm looking for a good programming font that lets me add comments and string literals in Unicode, usually Japanese and Chinese along with some Latin and Cyrillic languages. So far the situation seems to be "complete, monospace, free, pick 2" and Google is failing me with this (maybe because there are no good ones?). The best I found is Arial Unicode but it's not monospace, which is a big nuisance for me and the editors I use. Not to mention Python indentation when I'm coding Python. (Links, edits are welcome)

  • Django Error: NameError name 'current_datetime' is not defined

    - by Diego
    I'm working through the book "The Definitive Guide to Django" and am stuck on a piece of code. This is the code in my settings.py: ROOT_URLCONF = 'mysite.urls' I have the following code in my urls.py from django.conf.urls.defaults import * from mysite.views import hello, my_homepage_view urlpatterns = patterns('', ('^hello/$', hello), ) urlpatterns = patterns('', ('^time/$', current_datetime), ) And the following is the code in my views.py file: from django.http import HttpResponse import datetime def hello(request): return HttpResponse("Hello World") def current_datetime(request): now = datetime.datetime.now() html = "<html><body>It is now %s.</body></html>" % now return HttpResponse(html) Yet, I get the following error when I test the code in the development server. NameError at /time/ name 'current_datetime' is not defined Can someone help me out here? This really is just a copy-paste from the book. I don't see any mistyping.

  • RhinoMocks AAA Syntax

    - by Bill Campbell
    Hi, I've spent a good part of the day trying to figure out why a simple RhinoMocks test doesn't return the value I'm setting in the return. I'm sure that I'm just missing something really simple but I can't figure it out. Here's my test: [TestMethod] public void CopyvRAFiles_ShouldCallCopyvRAFiles_ShouldReturnTrue2() { FileInfo fi = new FileInfo(@"c:\Myprogram.txt"); FileInfo[] myFileInfo = new FileInfo[2]; myFileInfo[0] = fi; myFileInfo[1] = fi; var mockSystemIO = MockRepository.GenerateMock<ISystemIO>(); mockSystemIO.Stub(x => x.GetFilesForCopy("c:")).Return(myFileInfo); mockSystemIO.Expect(y => y.FileCopyDateCheck(@"c:\Myprogram.txt", @"c:\Myprogram.txt")).Return("Test"); CopyFiles copy = new CopyFiles(mockSystemIO); List<string> retValue = copy.CopyvRAFiles("c:", "c:", new AdminWindowViewModel(vRASharedData)); mockSystemIO.VerifyAllExpectations(); } I have an interface for my SystemIO class I'm passing in a mock for that to my CopyFiles class. I'm setting an expectation on my FileCopyDatCheck method and saying that it should Return("Test"). When I step through the code, it returns a null insteaed. Any ideas what I'm missing here? Here's my CopyFiles class Method: public List<string> CopyvRAFiles(string currentDirectoryPath, string destPath, AdminWindowViewModel adminWindowViewModel) { string fileCopied; List<string> filesCopied = new List<string>(); try { sysIO.CreateDirectoryIfNotExist(destPath); FileInfo[] files = sysIO.GetFilesForCopy(currentDirectoryPath); if (files != null) { foreach (FileInfo file in files) { fileCopied = sysIO.FileCopyDateCheck(file.FullName, destPath + file.Name); filesCopied.Add(fileCopied); } } //adminWindowViewModel.CheckFilesThatRequireSystemUpdate(filesCopied); return filesCopied; } catch (Exception ex) { ExceptionPolicy.HandleException(ex, "vRAClientPolicy"); Console.WriteLine("{0} Exception caught.", ex); ShowErrorMessageDialog(ex); return null; } } I would think that "fileCopied" would have the Return value set by the Expect. The GetFilesForCopy returns the two files in myFileInfo. Please Help. :) thanks in advance!
