Convert Word File to PDF Using C# dLL

It works in local system but not working on Server it shows object reference error

Object reference not set to an instance of an object." line WordToPDF.Word2Pdf.Word2PdfCOnversion()

Conversion took 2 minutes and 29 seconds. word file size: 183 KB

On my local machine works fine, but on server gives this error; "Object reference not set to an instance of an object." line WordToPDF.Word2Pdf.Word2PdfCOnversion()

Unhandled Exception: System.TypeLoadException: Could not load type 'WordToPDF.Word2Pdf' from assembly 'WordToPDF, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

Great Teddy Kurian, I have tried in vs2019 and it's working perfectly. this is a very simple solution.

This library use word interop. Word has to be instaled in the computer. Adding, it does not work in a web server.

I got this error "the document window is not activated."

Work well, but comments in word file is still display on PDF file.

Oops. It didn't work. I got this runtime error: System.InvalidCastException: 'Unable to cast COM object of type 'Microsoft.Office.Interop.Word.ApplicationClass' to interface type 'Microsoft.Office.Interop.Word._Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{00020970-0000-0000-C000-000000000046}' failed due to the following error: Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED)).'

This didn't work. I got this runtime error on the call to xxx:

Virustotal.com marks this dll as trojan. TScope.Trojan.MSIL

Its not working.. throw exception as object reference issue at the end

Not working on server. you need MS office installed

Must use cominterop ..terribly slow

I've tried it using vs 2019, and it works perfectly. Thank you

Hi Teddy, Thanks for sharing this code. I am able to convert docx to pdf. I just want to know whether "WordToPDF.dll" is third party dll or has been developed by you. Please could you let me know license information to use this dll. Will there be any technical support?

Why i am getting "This method or property is not available because a document window is not active.Microsoft Word", even i installed MS office on server. The WordToPDF works only with Console application and it does not work with WebAPI.

Import Namespace does not exist error: I have an ASPX app in VB.Net (VS 2012) and am attempting to use this dll. I downloaded and placed the dll in the bin folder for the project, added a reference to it in project references, added an Imports WordToPdf line, and added the code to do the word to pdf processing. All is well so far and the syntax is correct. However, when I try to do a build, I get the above error, and the reference to WordToPDF is no longer available. Office 97 is installed on the machine, and this app also does word automation stuff. Any ideas on what the issue is?
