I need a way to have a link within a fram trigger a print (of another frame) on the browser's printer. I don't think that there is a way to do this directly with HTML but am wondering if there is a simple way to do it using either an ActiveX control or a small Javascript.

This app is going into a controlled Intranet environment and will be running on IE3.


TIA
Marty

One of the reasons I love searches on Microsofts Technical Support Site... Here are two suggestions for getting the results you want. However they dont seem to address the multiple frame idea but with a little modification you should be able to get shift focus to the frame you want to print with the code then implement the print function with either a link or, as suggested here, a button:

What you need to do is call the GetDocument() method that returns an IDispatch*. Using the IDispatch*, call QueryInterface() on IID_IOleCommandTarget. With the object pointer returned, call Exec(NULL, OLECMDID_PRINT, 0, NULL,NULL).

Examples
1)
 void CAboutDlg::OnPrint()
   {
       CWnd* pWnd = GetFocus ();

       m_ctlWebBrowser.SetFocus ();
       // send Ctrl-P
       keybd_event (VK_CONTROL, 0, 0, 0);
       keybd_event ('P', 0, 0, 0);

       // set focus to control that previously had focus
       if (pWnd);
           pWnd->SetFocus ();
   }

2)

#include <docobj.h> -- This comes with the Internet Client SDK

   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();
   }

I have not tried this yet but it seems sound. Let me know how you make out

Understood, I will see what kind of information I can dig up this evening and get you something either before 12am EST tomorrow or first thing in the morning. In the meantime try to get at least a downloadable copy of a SDK from either Sun or Microsoft. They have demos that will work fine for what we are trying to accomplish and I will see if I can produce a script instead.
