We are not using the builtin toolbar. Instead we display our own. I want to get it working because we will using the same thing to print whatever is displayed in the activex control (which may not be a pdf in the future but maybe a webpage or xml document).

I have found some information on doing it in Delphi that I am trying to translate to VfP:

UPDATE:

I think it might be:

thisform.webcontrol.ExecWb(6,0,0,0)

The control has a method execwb():

// constants useful when printing
SHDocVw.OLECMDID Print = SHDocVw.OLECMDID.OLECMDID_PRINT;
// use this value to print without prompting
// SHDocVw.OLECMDEXECOPT PromptUser =
// SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_PROMPTUSER;
SHDocVw.OLECMDEXECOPT DontPromptUser =
SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER;

if (!IsPrinterEnabled() ) return;
// print without prompting user
axWebBrowser1.ExecWB(Print, DontPromptUser, ref o, ref o);
// to prompt the user with printer settings
// axWebBrowser1.ExecWB(Print, PromptUser, ref o, ref o);
}

ExecWB( OLECMDID_PRINT, OLECMDEXECOPT_PROMPTUSER );
