Is there any way I can replace bookmarks in .NET, without having MS Office installed in the PC? The reason because, the bookmark in my case needs to be replaced in server and the client is not willing to install MS OFFICE at server side. Is there any .NET api's ore 3rd party api's which will do the job for me?
Many Thanks Girish
Given it's a bad idea to use the Office Automation API on a server anyway, don't worry about not having Office installed. Source: http://support.microsoft.com/kb/257757/en-us
If your documents are all the new Office Open XML (OOXML, .docx etc) format then you can open them as a *.zip file and modify the XML that defines the Document bookmarks. See here for more information: http://msdn.microsoft.com/en-us/library/office/bb448854(v=office.15).aspx Warning: the Office Open XML library is very bare-bones, so I hope you're billing by the hour.
The only other option (besides doing everything yourself, which you really don't want to do) is to use a third-party library and so far the only one I can recommend is Aspose ( http://www.aspose.com/ ), but it's expensive.
Disclaimer: I am a Microsoft employee, however this personal recommendation is from my own experience. I do not work on Office.
