  • What is the process of turning HTML into Postscript programmatically

    - by Dean
    I am trying to understand what the process is of turning HTML into a PDF/Postscript programmatically All Google searches turn up libraries to do this, but I am more interested in the actual process required. I know you could just set up a Postscript printer and print directly to that, but some of these libraries appear to create the PDF on the fly to allow previews etc. has anyone had any experience in this, or can provide any guidance?

  • Convert html/css print media display to .doc with appropriate page breaks?

    - by DevelopingChris
    I'm looking to export a page that looks good in print media, to word. Can this be done automatically, or mostly automatically with office apis? The alternative is to create a program that reads all our style meta data and font meta data and convert to word and force a download. The issue is our style metadata is already built for css, its a web app after all. And writing my own css parser, doesn't sound like a good use of time.

  • Convert byte array to understandable String

    - by Ender
    I have a program that handles byte arrays in Java, and now I would like to write this into a XML file. However, I am unsure as to how I can convert the following byte array into a sensible String to write to a file. Assuming that it was Unicode characters I attempted the following code: String temp = new String(encodedBytes, "UTF-8"); Only to have the debugger show that the encodedBytes contain "\ufffd\ufffd ^\ufffd\ufffd-m\ufffd\ufffd\/ufffd \ufffd\ufffdIA\ufffd\ufffd". The String should contain a hash in alphanumerical format. How would I turn the above String into a sensible String for output?

  • Transform PDF to HTML, keep layout

    - by Tgr
    What methods are there to transform a PDF to HTML? It could be anything - online service, software, library. (Opensource preferred. In the last case, php or python would be preferred.) It has to keep the original layout (including page numbers, footnotes and such), keep the images (combining them to one single background image per page is acceptable) and keep the links. It should preferably output valid XHTML and clean up PDF features such as ligatures, but if there is some post-processing required, I can live with that. Something with a clean, relatively semantic HTML output would be great. The closest one I found was zamzar.org, but it choked on links. (Also, the HTML output is an ugly heap of absolutely positioned divs and needs post-processing because of encoding problems.)

  • Select...Case VB.NET to C# Equivalent

    - by Alex Essilfie
    I just started using C# and I've got a couple of issues. I hook several controls to one event handler as in the following and I want to perform a slightly different action for each control: Private Sub Button_Click(sender as Object, e as EventArgs) _ Handles button1.Click, Button2.Click 'do a general activity Select CType(sender, Button).Name Case button1.Name 'do something Case button2.Name 'do something else Case Else 'do the defalut action End Select End Sub Is there any way of doing the above select statement in C# without having to use nested ifs?

  • Java text to applet converter ... is there such a thing?

    - by Jahkr
    Let's say you have this program: public class sample public static void main(String args[]) { System.out.println("Hello world!"); } } ... is there a converter that will turn it into this: import java.applet.Applet; import javax.swing.*; public class sample extends JApplet { public static JTextArea area; public void init() { area = new JTextArea(); add(area); area.append("Hello world!"); } } I mean, I can do it by hand... but it would take some time.

  • Valid signed Hex to long function

    - by Ben
    I am trying to convert a 24bit Hexadecimal string (6 characters) signed in two's complement to a long int in C. This is the function I have come up with: long int hex2li (char string[]) { char *pEnd; long int result = strtol (string, &pEnd, 16); if (strcmp (pEnd, "") == 0) { if (toupper (string[0]) == 'F') { return result - 16777216; } else { return result; } } return LONG_MIN; } Is it valid? Is there a better way of doing this?

  • Convert String value format of YYYYMMDDHHMMSS to C# DateTime

    - by SARAVAN
    I have a need to convert a string value in the form "YYYYMMDDHHMMSS" to a DateTime. But not sure on how, may be a DateTime.Tryparse can be used to make this happen. Or is there any other way to do it. I can do this using some string operations to take "YYYYMMDD" alone, convert to a datetime and then add HH, MM, SS separately to that DateTime. But is there any DateTime.TryParse() methods that I can use in one line to convert a "YYYYMMDDHHMMSS" format string value to a DateTime value?

  • Function that converts hex color values to an approximate color name?

    - by dclowd9901
    I don't suppose anyone knows of a function (PHP, preferably) that can take a hex color code and give an approximate color name for that hex value. I don't need a solution with 100s of colors. Even if it just amounted to the colors white, black, red, green blue, brown orange and yellow, I'd be pretty well in shape. If you don't know of an existing resource, does anyone know of a good way to approach this problem? Thanks in advance for the help.

  • Problem convert column values from VARCHAR(n) to DECIMAL

    - by Kevin Babcock
    I have a SQL Server 2000 database with a column of type VARCHAR(255). All the data is either NULL, or numeric data with up to two points of precision (e.g. '11.85'). I tried to run the following T-SQL query but received the error 'Error converting data type varchar to numeric' SELECT CAST([MyColumn] AS DECIMAL) FROM [MyTable]; I tried a more specific cast, which also failed. SELECT CAST([MyColumn] AS DECIMAL(6,2)) FROM [MyTable]; I also tried the following to see if any data is non-numeric, and the only values returned were NULL. SELECT ISNUMERIC([MyColumn]), [MyColumn] FROM [MyTable] WHERE ISNUMERIC([MyColumn]) = 0; I tried to convert to other data types, such as FLOAT and MONEY, but only MONEY was successful. So I tried the following: SELECT CAST(CAST([MyColumn] AS MONEY) AS DECIMAL) FROM [MyTable]; ...which worked just fine. Any ideas why the original query failed? Will there be a problem if I first convert to MONEY and then to DECIMAL? Thanks!

  • get pure text form odt file in console

    - by naugtur
    I am looking for a small linux tool that would be able to extract text from odt file. It just needs to be human-readable and it can have problems with complicated objects etc. It's almost a duplicate of this question but I need it to be small and have no dependencies on OpenOffice or X server I remember having a 1MB MS-DOS program that could render .doc files quite readibly (with some weird markup getting through from time to time), so i expect it to be possible in the linux world too ;)

  • Convert VB6 Randomize to C#

    - by Thomas G. Mayfield
    I'm writing a C# frontend to a legacy database that uses VB6 Rnd() and Randomize() methods for user password encryption. The encryption function is very simplistic and really not all that secure, but it's what all current passwords are stored with. What I'd like to be able to do is authenticate legacy users from a C# application. I can write new encryption (or preferably hashing) code for VB6 so that all future users have a more secure password, and that can be duplicated in C#. But I don't want to require current users to have had their password reset before they can use the new frontend. Is there any way I can reimplement that algorithm in C# so that it produces identical results to the legacy VB6 code?

  • How to use the Bass library to convert audio to another format (using C#)

    - by Siemsen
    Good day everyone and happy holidays. I'm trying to create a "simple" program that allows me to create a list of video files (Youtube video's to be precise) that are then run through by my program and converted any given format to pure MP3 audio. For this purpose I'm trying to use the BASS.dll and well it isn't going so well. I was wondering if anyone has used BASS to convert from one audio format to another? Or is there another library better suited for this?

  • XML::XML2JSON "0" Element

    - by Kevin C
    I'm using XML::XML2JSON in Perl to convert JSON data to XML, I am passing through the following data (snippet): {"question":{"isrequired":{"$t":"0"}}} and when I use the XML:XML2JSON-json2xml function to convert the JSON data into XML, I get the following (snippet): <isrequired/> I need to retain the "0" element in the "isrequired" tag, because at times, I will have empty JSON elements, and need the empty XML tag. I think the documentation is a bit vague (either that, or I don't understand it), but is this possible to do with this module? I would appreciate the help. Thanks.

  • changing the serialization procedure for a graph of objects (.net framework)

    - by pierusch
    Hello I'm developing a scientific application using .net framework. The application depends heavily upon a large data structure (a tree like structure) that has been serialized using a standard binaryformatter object. The graph structure looks like this: <serializable()>Public class BigObjet inherits list(of smallObject) end class <serializable()>public class smallObject inherits list(of otherSmallerObjects) end class ... The binaryFormatter object does a nice job but it's not optimized at all and the entire data structure reaches around 100Mb on my filesystem. Deserialization works too but it's pretty slow (around 30seconds on my quad core). I've found a nice .dll on codeproject (see "optimizing serialization...") so I wrote a modified version of the classes above overriding the default serialization/deserialization procedure reaching very good results. The problem is this: I can't lose the data previosly serialized with the old version and I'd like to be able to use the new serialization/deserialization method. I have some ideas but I'm pretty sure someone will be able to give me a proper and better advice ! use an "helper" graph of objects who takes care of the entire serialization/deserialization procedure reading data from the old format and converting them into the classes I nedd. This could work but the binaryformatter "needs" to know the types being serialized so........ :( modify the "old" graph to include a modified version of serialization procedure...so I'll be able to deserialize old file and save them with the new format......this doesn't sound too good imho. well any help will be higly highly appreciated :)

  • Cannot initialize non-const reference from convertible type

    - by Julien L.
    Hi, I cannot initialize a non-const reference to type T1 from a convertible type T2. However, I can with a const reference. long l; const long long &const_ref = l; // fine long long &ref = l; // error: invalid initialization of reference of // type 'long long int&' from expression of type // 'long int' Most problems I encountered were related to r-values that cannot be assigned to a non-const reference. This is not the case here -- can someone explain? Thanks.

  • Convert this VB code to C#?

    I was wondering if anyone would be able to help me convert the below code to c#? From what I have read it seems to be similar however I am not sure if my 'case' statements are still able to be used?
