Upating a PDF file using Adobe SDK and VB.Net. Text and Date fields update and save without any problems, but Check Boxes will update, but not save. If I display the PDF file after updating the Check Boxes are checked, but after PDF file is saved they are not checked. The PDF file was created with LiveCycle. To test my program I created a PDF file with Acrobat. The Check Boxes update and save on the PDF created with Acrobat, but the Check Boxes do not save on PDF created with LiveCycle. Is there a different method to upate/save Check Boxes on a PDF created with LiveCycle?
