But remember that this is biblographic information, it is not available in metadata of this pdf. i want to access Article Type (%O), Title (%T), Authors (%A), Date (%D) and (%I) and show it to different assigned textbox in window form. i am using C# if any one have any code for this. or guide me how to do this.
