  • HTML to RTF Converter for .NET

    - by nickyt
    I've already seen lots of posts on the site for RTF to HTML and some other posts talking about some HTML to RTF converters, but I'm really trying to get a full breakdown of what is considered the most widely used commercial product, open source product or if people recommend going home grown. Apologies if you consider this a duplicate question, but I'm trying to create a product matrix to see what is the most viable for our application. I also think this would be helpful for others. The converter would be used in an ASP.NET 2.0 application (we're upgrading to 3.5 shortly but still sticking with WebForms) using SQLServer 2005 (soon 2008) as the DB. From reading a few posts, SautinSoft appears to be popular as a commercial component. Are there other commercial components that you'd recommend for converting HTML to RTF? Price does matter, but even if it's a little on the expensive side, please list it. For open source, I read that OpenOffice.org can be run as a service so that it can convert files. However, this appears to be only Java based. I imagine, I'd need some kind of interop to use this? What .NET open source components, if any, are out there for converting HTML to RTF? For home grown, is an XSLT the way to go with XHTML? If so, what component do you recommend for generating XHTML? Otherwise, what other home grown avenuses do you recommend. Also, please note that I currently don't care so much about RTF to HTML. If a commercial component offers this and the price is still the same, fine, otherwise please don't mention it.

  • Swig typecast to derived class?

    - by Zack
    I notice that Swig provides a whole host of functions to allow for typecasting objects to their parent classes. However, in C++ one can produce a function like the following: A * getAnObject() { if(someBoolean) return (A *) new B; else return (A *) new C; } Where "A" is the parent of classes "B" and "C". One can then typecast the pointer returned into being a "B" type or "C" type at one's convenience like: B * some_var = (B *) getAnObject(); Is there some way I can typecast an object I've received from a generic-pointer-producing function at run-time in the scripting language using the wrappers? (In my case, Lua?) I have a function that could produce one of about a hundred possible classes, and I'd like to avoid writing an enormous switch structure that I'd have to maintain in C++. At the point where I receive the generic pointer, I also have a string representation of the data type I'd like to cast it to. Any thoughts? Thanks! -- EDIT -- I notice that SWIG offers to generate copy constructors for all of my classes. If I had it generate those, could I do something like the following?: var = myModule.getAnObject(); -- Function that returns an object type-cast down to a pointer of the parent class, as in the function getAnObject() above. var = myModule.ClassThatExtendsBaseClass(var); -- A copy constructor that SWIG theoretically creates for me and have var then be an instance of the inheriting class that knows it's an instance of the inheriting class?

  • serializing type definitions?

    - by Dave
    I'm not positive I'm going about this the right way. I've got a suite of applications that have varying types of output (custom defined types). For example, I might have a type called Widget: Class Widget Public name as String End Class Throughout the course of operation, when a user experiences a certain condition, the application will take that output instance of widget that user received, serialize it, and log it to the database noting the name of the type. Now, I have other applications that do something similar, but instead of dealing with Widget, it could be some totally random other type with different attributes, but again I serialize the instance, log it to the db, and note the name of the type. I have maybe a half dozen different types and don't anticipate too many additional ones in the future. After all this is said and done, I have an admin interface that looks through these logs, and has the ability for the user to view the contents of this data thats been logged. The Admin app has a reference to all the types involved, and with some basic switch case logic hinged upon the name of the type, will cast it into their original types, and pass it on to some handlers that have basic display logic to spit the data back out in a readable format (one display handler for each type) NOW... all this is well and good... Until one day, my model changed. The Widget class now has deprecated the name attribute and added on a bunch of other attributes. I will of course get type mismatches in the admin side when I try to reconstitute this data. I was wondering if there was some way, at runtime, i could perhaps reflect through my code and get a snapshot of the type definition at that precise moment, serialize it, and store it along with the data so that I could somehow use this to reconstitute it in the future?

  • mysql replace accented characters

    - by pixeline
    Hi, i would like to generate strict alphanumeric character logins from users' first and lastname. Since many of them are foreigners, their names have special characters (é, è, ï, ...). I would like to remove the accents (e,e,i,...) in the logins. Here is my query. Is there a character set that does not contain accents? UPDATE contacts SET login=CONVERT(LOWER(CONCAT(firstname,'.',lastname)) USING utf8);

  • Cast then check or check then cast?

    - by jamesrom
    Which method is regarded as best practice? Cast first? public string Describe(ICola cola) { var coke = cola as CocaCola; if (coke != null) { string result; // some unique coca-cola only code here. return result; } var pepsi = cola as Pepsi; if (pepsi != null) { string result; // some unique pepsi only code here. return result; } } Or should I check first, cast later? public string Describe(ICola cola) { if (cola is CocaCola) { coke = (CocaCola) cola; string result; // some unique coca-cola only code here. return result; } if (cola is Pepsi) { pepsi = (Pepsi) cola; string result; // some unique pepsi only code here. return result; } } Can you see any other way to do this?

  • How do I convert decimal numbers to binary in Perl?

    - by David
    I am trying to make a program that converts decimal numbers or text into binary numbers in perl. The program asks for user input of a character or string , and then prints out the result to the console. How do I do this? My code I have been working on is below, but i cannot seem to fix it. print "Enter a number to convert: "; chomp($decimal = <STDIN>); print "\nConverting $number to binary...\n"; $remainder = $decimal%2; while($decimal > 0) { $decimal/2; print $remainder; }

  • WPF TypeConverter ConvertTo not firing

    - by JFoulkes
    Hi, I have a dependency property in a class which I need to be converted to a string. I have added the TypeConverty attribute on the property. The type I am converting is the .net Style class. [TypeConverter(typeof(BulletStyleTypeConverter))] public Style BulletStyle { get { return (Style)GetValue(BulletStyleProperty); } set { this.SetValue(BulletStyleProperty, value); } } When I put the string "Rectangle" in for BulletStyle in xaml it hits the ConvertFrom method in my converter. However, when I use XamlWriter.Save() to serialise this, the property does not appear as an attribute in the string which is produced. I have implemented ConvertTo and put a breakpoint on, which is never hit. I have implemented CanConvertTo and put a breakpoint on, which IS hit and returns true. So i'm stumped as to why ConvertTo never fires.

  • How do you use any2mobi command line tool (part of Calibre) to make mobi files from HTML?

    - by Paul Chernoch
    I am on MAC OS X 10.5.5. I installed Calibre, a tool for converting e-book files from one format to another. It has a GUI as well as command line tools. I am trying to run the command line tool "any2mobi" to convert HTML files to MOBI pocket format or Kindle AZW format, with a TOC. I get the error "-bash: any2mobi: command not found". Clearly, any2mobi is not in my path. Where is it? I tried searching but came up empty. I installed version 0.6.0b6 of Calibre.

  • Avoiding unsafe cast for generic situation involving runtime passing of class

    public class AutoKeyMap<K,V> { public interface KeyGenerator<K> { public K generate(); } private KeyGenerator<K> generator; public AutoKeyMap(Class<K> keyType) { // WARNING: Unchecked cast from AutoKeyMap.IntKeyGen to AutoKeyMap.KeyGenerator<K> if (keyType == Integer.class) generator = (KeyGenerator<K>) new IntKeyGen(); else throw new RuntimeException("Cannot generate keys for " + keyType); } public void put(V value) { K key = generator.generate(); ... } private static class IntKeyGen implements KeyGenerator<Integer> { private final AtomicInteger ai = new AtomicInteger(1); @Override public Integer generate() { return ai.getAndIncrement(); } } } In the code sample above, what is the correct way to prevent the given warning, without adding a @SuppressWarnings, if any?

  • Convert binary information to regular data type without outside modules in python.

    - by vgm64
    Hello World. I'm tasked with reading a poorly formatted binary file and taking in the variables. Although I need to do it in C++ (ROOT, specifically), I've decided to do it in python because python makes sense to me, but my plan is to get it working in python and then tackle re-writing in in C++, so using easy to use python modules won't get me too far later down the road. Basically, I do this: In [5]: some_value Out[5]: '\x00I' In [6]: ''.join([str(ord(i)) for i in some_value]) Out[6]: '073' In [7]: int(''.join([str(ord(i)) for i in some_value])) Out[7]: 73 And I know there has to be a better way. What do you think?

    - by Patrick Cuff
    I have a tab delimited file where each record has a timestamp field in 12-hour format: mm/dd/yyyy hh:mm:ss [AM|PM]. I need to quickly convert these fields to 24-hour time: mm/dd/yyyy HH:mm:ss. What would be the best way to do this? I'm running on a Windows platform, but I have access to sed, awk, perl, python, and tcl in addition to the usual Windows tools.

  • The type or namespace name 'Mvc' does not exist in the namespace 'System.Web'

    - by Guy
    After converting a Hybrid ASP.NET MVC1 app to MVC2 I'm getting the following error when I try and run the application: The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?) The allegeded culprit in the web.config file is System.Web.Mvc: <namespaces> <add namespace="System.Web.Mvc"/> <add namespace="System.Web.Mvc.Ajax"/> <add namespace="System.Web.Mvc.Html"/> So far my investigation seems to lead me to believe that version 2 of System.Web.Mvc is not installed or has not been picked up. I've tried creating a File New Project based on MVC 2 and that's picking up the new (v2) version of MVC. I've also converted some other projects (that were not hybrids) and they've converted without problem to MVC2. I've also uninstalled MVC1 to try and remove references to it from the GAC. However, none of this has worked. Any ideas?

  • Building a directory tree from a list of file paths

    - by Abignale
    I am looking for a time efficient method to parse a list of files into a tree. There can be hundreds of millions of file paths. The brute force solution would be to split each path on occurrence of a directory separator, and traverse the tree adding in directory and file entries by doing string comparisons but this would be exceptionally slow. The input data is usually sorted alphabetically, so the list would be something like: C:\Users\Aaron\AppData\Amarok\Afile C:\Users\Aaron\AppData\Amarok\Afile2 C:\Users\Aaron\AppData\Amarok\Afile3 C:\Users\Aaron\AppData\Blender\alibrary.dll C:\Users\Aaron\AppData\Blender\and_so_on.txt From this ordering my natural reaction is to partition the directory listings into groups... somehow... before doing the slow string comparisons. I'm really not sure. I would appreciate any ideas. Edit: It would be better if this tree were lazy loaded from the top down if possible.

  • TypeConverter prevents ApplyPropertyChanges in EntityFramework

    - by Felix
    I ran into an interesting problem (hopefully, interesting not just for me :) I am running Entity Framework 1 (.NET 3.5) and ASP.NET MVC 2. I have a Customer class that has many-to-one relationship with Country class (in other words, Country is a lookup table for customers - I described more in this post: http://stackoverflow.com/questions/2404801/explicit-casting-doesnt-work-in-default-model-binding ) I got TypeConverter to work; so I am getting a perfect object into controller's Post method. Create works fine; however, in Edit I am getting the following error when I call ApplyPropertyChanges: The existing object in the ObjectContext is in the Added state. Changes can only be applied when the existing object is in an unchanged or modified state. The controller code is fairly trivial: public ActionResult Edit(Customer customerToEdit) { if (ModelState.IsValid) { Customer cust = (Customer)context.GetObjectByKey( new EntityKey("BAEntities.Customers", "CustomerID", customerToEdit.CustomerID)); context.ApplyPropertyChanges(cust.EntityKey.EntitySetName, customerToEdit); context.SaveChanges(); } return View(...); } If I remove country from the form, it works fine; and if I assign dropdown value to EntityReference "manually" - it works as well. TypeConverter code is also fairly simple, but I've never used TypeConverter before, so I may be missing something here: public override object ConvertFrom(ITypeDescriptorContext typeContext, CultureInfo culture, object value) { if (value is string) { int countryID = Int16.Parse((string)value); Country country = (Country)context.GetObjectByKey( new EntityKey("BAEntities.Countries", "CountryID", countryID)); return country; } return base.ConvertFrom(typeContext, culture, value); }

  • Converting PDF to images using ImageMagick.NET - how to set the DPI

    - by Avi Pinto
    Hi, I'm trying to convert pdf files to images. ImageMagick is a great tool, and using the command line tool gets me desired result. but i need to do this in my code, So added a reference to http://imagemagick.codeplex.com/ And the following code sample renders each page of the pdf as an image: MagickNet.InitializeMagick(); using (ImageList im = new ImageList()) { im.ReadImages(@"E:\Test\" + fileName + ".pdf"); int count = 0; foreach (Image image in im) { image.Quality = 100; image.CompressType = mageMagickNET.CompressionType.LosslessJPEGCompression; image.Write(@"E:\Test\" + fileName + "-" + count.ToString() + ".jpg"); ++count; } } The problem: IT LOOKS LIKE CRAP the rendered image is hardly readable. the problem i realized is it uses the default 72 DPI of ImageMagick. and i can't find a way to set it(96dpi or 120dpi gives good results) via the .Net wrapper. Am I missing something , or there is really no way to set it via this wrapper? Thanks

  • codes to convert from avi to asf

    - by George2
    Hello everyone, No matter what library/SDK to use, I want to convert from avi to asf very quickly (I could even sacrifice some quality of video and audio). I am working on Windows platform (Vista and 2008 Server), better .Net SDK/code, C++ code is also fine. :-) I learned from the below link, that there could be a very quick way to convert from avi to asf to support streaming better, as mentioned "could convert the video from AVI to ASF format using a simple copy (i.e. the content is the same, but container changes).". My question is after some hours of study and trial various SDK/tools, as a newbie, I do not know how to begin with so I am asking for reference sample code to do this task. :-) (as this is a different issue, we decide to start a new topic. :-) ) http://stackoverflow.com/questions/743220/streaming-avi-file-issue thanks in advance, George EDIT 1: I have tried to get the binary of ffmpeg from, http://ffmpeg.arrozcru.org/autobuilds/ffmpeg-latest-mingw32-static.tar.bz2 then run the following command, C:\software\ffmpeg-latest-mingw32-static\bin>ffmpeg.exe -i test.avi -acodec copy -vcodec copy test.asf FFmpeg version SVN-r18506, Copyright (c) 2000-2009 Fabrice Bellard, et al. configuration: --enable-memalign-hack --prefix=/mingw --cross-prefix=i686-ming w32- --cc=ccache-i686-mingw32-gcc --target-os=mingw32 --arch=i686 --cpu=i686 --e nable-avisynth --enable-gpl --enable-zlib --enable-bzlib --enable-libgsm --enabl e-libfaac --enable-pthreads --enable-libvorbis --enable-libmp3lame --enable-libo penjpeg --enable-libtheora --enable-libspeex --enable-libxvid --enable-libfaad - -enable-libschroedinger --enable-libx264 libavutil 50. 3. 0 / 50. 3. 0 libavcodec 52.25. 0 / 52.25. 0 libavformat 52.32. 0 / 52.32. 0 libavdevice 52. 2. 0 / 52. 2. 0 libswscale 0. 7. 1 / 0. 7. 1 built on Apr 14 2009 04:04:47, gcc: 4.2.4 Input #0, avi, from 'test.avi': Duration: 00:00:44.86, start: 0.000000, bitrate: 5291 kb/s Stream #0.0: Video: msvideo1, rgb555le, 1280x1024, 5 tbr, 5 tbn, 5 tbc Stream #0.1: Audio: pcm_s16le, 22050 Hz, mono, s16, 352 kb/s Output #0, asf, to 'test.asf': Stream #0.0: Video: CRAM / 0x4D415243, rgb555le, 1280x1024, q=2-31, 1k tbn, 5 tbc Stream #0.1: Audio: pcm_s16le, 22050 Hz, mono, s16, 352 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding frame= 224 fps=222 q=-1.0 Lsize= 29426kB time=44.80 bitrate=5380.7kbits/s video:26910kB audio:1932kB global headers:0kB muxing overhead 2.023317% C:\software\ffmpeg-latest-mingw32-static\bin> http://www.microsoft.com/windows/windowsmedia/player/webhelp/default.aspx?&mpver=11.0.6001.7000&id=C00D11B1&contextid=230&originalid=C00D36E6 then have the following error when using Windows Media Player to play it, does anyone have any ideas? http://www.microsoft.com/windows/windowsmedia/player/webhelp/default.aspx?&mpver=11.0.6001.7000&id=C00D11B1&contextid=230&originalid=C00D36E6

  • How can I Unescape and Reescape strings in .net?

    - by firoso
    So here's my situation. I am working on an editor for a communications channel that works over an RS232 serial ASCII terminal. Let's not go into detail for that ;-) To simplify, I need a textbox on a WPF control that can take in text like "Commit\r\n" (which is the .net string "Commit\r\n") and convert it back to "Commit\r\n" as a .net string. I was hoping for a string.Unescape() and string.Escape() method pair, but it doesn't seem to exist. Am I going to have to write my own? or is there a more simple way to do this?
