I am try to use axAcroPDF COM to display PDF file on my form , select text and highlight them. The PDF page can be rendered correctly. And I have noticed there are some buttons stay at right of the form , but they are all gray ,so I can not click these buttons to make the selected content highlight.
I have tested , to load the same PDF file with Adobe Reader, I can use all the function normally. I also tryed to use setCurrentHighLight() but is not work.
Please help me to solve this problem , Thanks a lot.
