In this web document collaborating tutorial page, users are supposed to get well informed of following aspects:
  • How to implement and activate web document annotation controls into VB project to draw and view annotations
  • How to start and configure VB.NET imaging application to create and add annotations to web source document
  • How to set the SQL database to save the created web annotations
  • How to store and load the annotations from SQL database by using VB.NET sample code
What should be noted on the above four sections is that the previous three parts will display the detailed guide on creating a client capture application that submits target multi-page document to a web service interface to a database. pdf editor in mvc, preview pdf, multipage tiff viewer, mvc open word document in browser, asp net replace text fro pdf free, how to show pdf file in c#, pdf viewer in mvc c#.
Implement Annotation Drawing and Viewing Controls in VB Project
Please note that before you can apply the web document annotating controls to draw and add markup, you are supposed to create a web document viewer in VB ASP.NET at first. After you have finished this operation, you can go on to follow guide tips below.
  1. Firstly, please start and activate the ShowAnnotations property of the WebThumbnailViewer;
  2. Secondly, begin and activate the AutoLinkThumbnailViewer in WebAnnotationsViwer;
  3. And then, drag an HTML button "btnStickyNote" to fix the annotations that will be created;
  4. At last, you need to add another "btnHighlighter" HTML button to highlight annotations.
Draw Annotations Within the VB.NET Web Document Application

  1. To save the created annotations as separate image fileS, you need to add an "varbinary(MAX)" annotations field to the SQL database first;
  2. Then you need to apply following query to the ImageDatabaseTableAdapter called GetAnnotations within SQL database;
  3. Last, go on adding following UpdateAnnotations query by using SQL code.
How to Save and Load Annotations from SQL Database
Please refer to following guide to store and load web document annotations from SQL database within VB.NET application.

Save Created Annotations in SQL Database

  1. Open the toolbox and drag a server button onto your form and with a user defined name;
  2. Double-click the button to create the event handler and copy the sample code to save annotations as XMP.
