Is there some way to turn off the read mode programmatically for adobe reader? I know that you can set this by modifying the Windows register table, but that doesn’t do me any good. When you go to a website to view a PDF in a supported browser using Reader X or Reader XI, you will see the Read Mode toolbar. The Read Mode toolbar is a semi-transparent toolbar which floats over the document as the above image. Since the Adobe reader X, the semi-transparent toolbar is showing while the user open the pdf files in brower. If the developer needs to disable user to save or print the pdf files, it’s necessary to hide the floating toolbar. In PDF Viewer Compnent, when the developer call the SetReadOnly method, the component will load pdf files and turn off the read mode. If you haven’t the pdf viewer component, you need to install the package firstly. Private Sub OpenPDF_Click() With CommonDialog1 .DefaultExt = ‘pdf’ .Filter = ‘PDF File Formats (*.pdf)|*.pdf|All Files (*.*) | *.* ||’ .FilterIndex = 1 End With CommonDialog1.ShowOpen PDFViewer1.Toolbars = False PDFViewer1.NavPanes = False PDFViewer1.Messages = False PDFViewer1.LoadFile CommonDialog1.FileName PDFViewer1.SetReadOnly End Sub Source.
