Good. The problem is that when opening a pdf with the following function:
CAcroAVDoc avdoc = new AcroAVDoc();
Automatically opens the adobe acrobat, I would like to know if there is any way to work with pdfs without seeing the adobe acrobat (I do not care if the process starts, I want it to at least not be seen by users)
Start the process first using Windows API to hide it. You may need to hide it multiple times. Be sure to accommodate the user who started with Acrobat open and visible, and would be upset if it becomes invisible Or is killed, losing their edits.
