Save PDF on Server

[sokjukim]

Hey, I know ActiveX is client technology. PDF-Xchange Viewer ActiveX opens PDF from local folder (or URL) and save PDF on local machine.
But we want to open PDF from our web server and edit/save back to web server. Do you have any API to post back PDF bytes to web server? or Any API to send data through web service? (We're using ASP.NET/C#)

Thanks,

Hi,

Viewer AX can open file by specified URL (in case that you want to read PDF from server). Also you can save PDF to IStream, so if you can upload this stream back to web server this may solve your problem. For now we don’t have any API that can help you to post data to web server.

I think istream is enough for us. Can you give (attach) some sample sources to use istream? Thanks,

We have two samples "OpenDocumentFromStream" and "SaveDocumentToStream" for C# (and VB.NET) which comes with the Viewer AX SDK (so you can find them in "Tracker Software\PDF-XChange Viewer SDK\Examples\C#Examples\" directory).

HTH.

Hey Corwin, Thanks for answer.

I'm using PDF-XChange viewer as a client-side control in ASP.NET page, which means I can't access to this client control from ASP.NET server-side codes. So I can't create iStream object and connect to PDF-XChange object as it does in SaveDocumentToStream examples. Any thought?

Hi,

As I can understand you can access to Client Side AX component with Server side code. Please see attached sample.

Hi, sokjukim.

Unfortunately, but we cannot upload any file by our ActiveX to remote server in current realization.
Probably you can use HTML's java script for this. For example, on client-side:
1. When OnLoadPage/OnUserClickOnOpenButton you may use ax.OpenDocument("http://server/path/doc1.pdf");
2. OnUserClickOnSaveChangesButton you may:
2.1 use ax.SaveDocument(0, "<temp_local_file_name>");
2.1' or use ax.SaveDocument(0, TempMemStreamObject);
2.2 upload local_file/memstream(?) by next code: http://www.aspheute.com/english/20000802.asp.

Feature for uploading documents will be added into the next version(V3).

Best Regards,
Vasyl.
