What is the ‘axAcroPDF’ control? What version of Reader?
It is an ActiveX control provided by Adobe Acrobat (AxAcroPDFLib.AxAcroPDF) to host a PDF in a windows form application. We are using version 10.1.2.
Ok. I think I understand you are using the Acrobat SDK. If that's true, you need to go to an SDK/developer forum.
