When we click on the "Print" button on the toolbar to implement the IE print function function, it is found that there is no "print"
The Machine Security dialog is displayed, and the program will automatically start printing documents. This feature is also used for Microsoft
Word. This feature is implemented in the application, the encoding is as follows:
Void cmybrowser :: onprint ()
{
LPOLECOMMANDTARGET PCMDTARG = NULL;
M_PDISP = m_webbbrowser2.getdocument (); // get the idispatch interface Pointer
Assert (m_pdisp);
m_pdisp-> queryinterface (IID_IOLCOMMANDTARGET, (LPVOID *) & pcmdtarg); // Query for OleCommandTarget Interface
Assert (pcmdtarg);
PCMDTARG-> EXEC (Null, // Call the olecommandtarget's exec method
OLECMDID_PRINT,
0,
NULL,
NULL
);
IF (PCMDTARG)
PCMDTARG-> Release (); // Release Document's Command Target
IF (m_pdisp)
m_pdisp-> release (); // Release Document's Dispatch Interfac
}
