dxf to pdf in asp.net - asp.net

Do you know a library that can convert a dxf file to pdf without having the autocad program installed ?
I'm looking to convert microsoft document too, but i know I can use the microsoft dll installed when you have office
Thanks

QCAD v3 has an utility called dwg2pdf which also can convert from dxf files. But the dwg/dxf importer requires a (reasonable priced) licence.
Inkscape has a command line option to convert to pdf. But currently it seems to have bug. It opens a confirmation popup even in no gui mode.
libreOffice can also convert dxf to pdf, but the result is not satisfying. The old oo convert via unoconv did yield better result.
There are other windows only solution I don't have experience with.

How to convert text symbols like ‰^“]€”õONŠ back to Japanese so I can google translate it to English? (Script?)

I am working with Mitsubishi PLC files that were originally commented in Japanese but then opened on English-only computers which converted the Japanese symbols to incomprehensible latin keyboard symbol combinations such as ‰^“]€”õONŠm”F(‘€ì”Õ1).
Being able to understand these comments would greatly enhance my ability to analyze and modify these files as I am required to do so for my work. If I could translate these back to Japanese symbols (I do have the Japanese language pack installed on my windows laptop), I could then translate these with Google Translate, which I know is not perfect, but is a lot better than ##$$##&^.
Does anyone have any ideas how this could be done? I figure that Windows must have interpreted the original characters somehow, and there may be a way to interpret them back to the original symbols.
I am thinking of trying to do some kind of character translation using a script in Python or Powershell or VBA (maybe I can create a map in Excel...)
Any ideas?
I can export these comments into CSV files so easy to get to and manipulate if I can figure out how....
This is an ongoing problem for me so I am willing to put some time into a solution.
I tried re-opening the oldest version of the files, in my computer with the Japanese language pack installed and no luck.
You can run your text through an ascii to hex converter and then through a hex to ascii converter in order to change the encoding without your system settings being in the way.

Multibyte characters reading problem in IronPdf

I am trying IronPDF. I want to insert PDF metadata to database which I read with IronPDF. However, some "ı" characters in the metadata are not read with IronPDF. Spaces are left in place of these characters. Here is my code sample:
var md = PdfDocument.FromFile("___PATH OF PDF FILE___");
var article_title = md.MetaData.Title;
When I copy paste string to Notepad++ it gives a result like this:
And here is the screenshot of application view:
Is there a way to solve this problem or is this a bug of IronPDF? If everything goes well, of course, I think of buying. But of course, if it fails on the first try, continue to iTextSharp.
EDIT: First of all, I apologize for Windows, which made me surprised. I struggled to get a new system up all day and unfortunately it's still visual studio etc. not to be installed. I added one of the files I had problems with in the below and the IronPDF version appears as 2019.7.0.0.
PDF file: https://yadi.sk/d/HwP9JWRWTzMlSA
First of all, since you haven't provided us with a sample PDF to work with; I've google some Turkish PDF documents having metadata with Turkish characters. This is the file that I came up with: link
As you can see above the Author metadata field has ı Turkish character.
Then I created a dotnet fiddle in order to test this file using IronPDF (with the latest available version - since you haven't specified any):
sample using IronPDF
The output from this sample is ElifCakroglu which is showing the exact same symptom when copied to Notepad++:
Playing with the encodings did not help resolving this issue. So I created another dotnet fiddle to test your alternative solution which was iTextSharp: sample using iTextSharp
This time everything was working as it should be: ElifCakıroglu
Note: I've also tried creating a Word 2016 document and saving it as a PDF then using that file with the above samples and both of them did not work (not accepting as a valid PDF) for some reason. After that I tried and online PDF document validator, but the file was fine. Then I used an online converter to change the PDF version with the default settings and used the output PDF with both samples and the surprising thing is that both of them worked correctly.
My conclusion is that iTextSharp is working consistently with both documents having metadata with Turkish characters present, while IronPDF works correctly 50% of the time.
I believe that this issue is resolved and can be tested in the 2020.9 release branch of IronPdf.

Opening Alteryx .yxdb files in R

Similar to the question below, I was wondering whether there is a way to open .yxdb files in R?
Open Alteryx .yxdb file in Python?
YXDB is Alteryx's own native format. I haven't seen or heard of anything else that can open it.
You could change your workflow to write to a CSV (or other compatible file) as well as writing to the YXDB file.
AFAIK there is no way yet for R to read yxdb files. I also export my Alteryx workflows to CSVs or use the R tool, read.Alteryx, and saveRDS to save it as a fast-loading binary file.

How to open .jl file

I want to open a .jl file and convert it to a readable file preferably in .xls format.
I do not have any any idea about Julia language.
Is there a file opener for jl files?
I came here with the same question, but since the file I was looking at was clearly JSON data, I did some more searching.
The .jl file extension also refers to JSON lines, sometimes instead a .jsonl extension.
More here: http://jsonlines.org/
You can search for .json to Excel to find a converter, e.g. https://json-csv.com/ (this worked fine on my JSON lines file).
A .jl file is a julia script.
It is source code.
Not data.
You can open it up in any text editor, e.g. notepad on windows.
However, it won't normally contain anything useful to you unless you want to edit that code.
(It might contain some array literals that you want, I guess)
Perhaps you mean to ask "How can I open a .jld file"?
Which is a julia HDF5 file.
In which case please ask another question.
As I see, Julia is a script language therefor the file can be opened in a text editor like Notepad++, Vim, etc. Do not use word processor (like LibreOffice Writer) if you want to modify it, but it's OK if you want to read only.

Flex: Write data to file to open in Excel

I have a Flex application with a couple of DataGrids with data. I'd like to save the data to a file so that the user can keep working with them in Excel, OpenOffice or Numbers.
I'm currently writing a csv file straight off, which opens well in OpenOffice or Numbers, but not in Excel. The problem is with the Swedish characters ÅÄÖ, which turn up as other characters when opening in Excel. Converting (in Notepad++) the csv-file to ANSI encoding makes the ÅÄÖ show up correctly in Excel.
Is there any way to write ANSI-encoded files straight from Flex?
Any other options for writing a file that can be opened in Excel and OpenOffice?
(I've looked at the as3xls library, but according to the comments those files cannot be opened in OpenOffice)
Using the writeMultiByte function from the ByteArray class allows you to specify a character set. See :
http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/flash/utils/ByteArray.html#writeMultiByte%28%29
There is also the option of the as3xls package at http://code.google.com/p/as3xls/. I like this as it comes out as a straight excel file that can also be easily opened in open office as well.
