The Web Browser control is Submitted by Sergey on November 23, 2010 - 14:09.

The Web Browser control is part of IE. IOW, it'll be available as long as you have IE installed o n PC. It can display HTML and s ome othe r file types natively but for the res t you'll have to install appropriate plugins. reply

PDF suddenly in separate Adobe window (not inside form) Submitted by Ginny (not verified) on February 3, 2011 - 10:04.

Hi, i have bee n using this code for about 6 months now and it's bee n wo rking great (thank you!). Howe ver, in the last w ee k or so, sudde nly the PDF opens up in it's own Adobe W indow rather than inside the VFP9 form it was originally displaying in. The reason I like it inside the form is because it forces the user to exit (I put an Exit button o n the form to release it). Suddenly it open s the PDF in a sepa rate Adobe Acrobat w indow, and ope ns the blank form behind Adobe. In order to e xit, I have to exit out o f Adobe, then hit the Exit button o f the form (which is blank because the P DF didn't load inside it). Any idea why this would sudd enly happen? No code ha s bee n changed. Thanks! reply
