Microsoft's Knowledge Base article Q156732 supposedly gives the answer to this question, but not in terms that I can easily apply to VFP. It describes two possible methods: the first is a specialized gimmick that entails setting focus and issuing a Ctrl+P, the second approach gets into API calls. I'm more interested in a translation into VFP of the second method, because the first is less general, and besides, it doesn't work in VFP, as far as I can tell.
It seems that when a WebBrowser control has the focus, it uses its own keyboard buffer, so any KEYBOARD command issued via VFP is futile - the browser control doesn't see it. Similarly, any ON KEY LABEL... or VFP menu-based hot keys appear to be inoperative when the browser control has the focus.
Anyway, even if I could solve the Print problem with KEYBOARD, what I'm really after is the more general problem of getting to ALL of the other ways of controlling a WebBrowser object that have no corresponding PEMs visible to VFP. I gather that this is doable via DECLARE - DLL stuff, but I have yet to see a single comprehensible example in VFP terms. It would be mighty instructive to see a translation of the Q156732 example into VFP code!
Excerpt from Q156732:
// DOCOBJ.H comes with the ActiveX SDK and is installed by default in
// the "\INetSDK\Include" directory
#include
void CAboutDlg::OnPrint()
{
LPDISPATCH lpDispatch = NULL;
LPOLECOMMANDTARGET lpOleCommandTarget = NULL;
lpDispatch = m_ctlWebBrowser.GetDocument();
ASSERT(lpDispatch);
lpDispatch->QueryInterface(IID_IOleCommandTarget,
(void**)&lpOleCommandTarget);
ASSERT(lpOleCommandTarget);
lpDispatch->Release();
// print contents of web browser control
lpOleCommandTarget->Exec(NULL, OLECMDID_PRINT, 0, NULL,NULL);
lpOleCommandTarget->Release();
}
Should I use the object.Document property instead of GetDocument?
Is SHDOCVW.DLL the one that should be specified in DECLARE - DLL statement(s)?
How do I declare and use these functions, which are being invoked with a pointer->function(...) syntax in the example above? Other examples that I've seen in VFP's Solution.APP don't use this construct.
Any help on this would be greatly appreciated.
