Implement web page printing functions similar to IE

 

 

When we click "print" on the toolbar to implement the print function of IE, we find that "print" does not exist.

The host installation dialog box is displayed, and the program starts to print documents automatically. This feature is also usedMicrosoft

 Word. To implement this feature in an application, the encoding is as follows:

 

Void CMyBrowser: OnPrint ()

{

LPOLECOMMANDTARGET pCmdTarg = NULL;

 

M_pDisp = m_WebBrowser2.GetDocument (); // get the IDispatch interface pointer

ASSERT (m_pDisp );

 

M_pDisp-> QueryInterface (IID_IOleCommandTarget, (LPVOID *) & pCmdTarg); // query for olecommandtarget interface

ASSERT (pCmdTarg );

 

PCmdTarg-> Exec (NULL, // call the olecommandtargets Exec method

OLECMDID_PRINT,

0,

NULL,

NULL

);

 

 

If (pCmdTarg)

PCmdTarg-> Release (); // release documents command target

 

If (m_pDisp)

M_pDisp-> Release (); // release documents dispatch interfac

 

}
