Printing In MFC Application

问题:

How can I print a document using MFC Dialog Based Application? I have made a print button. After clicking on this button, I want print of some document or some text.

You can create an invisble CHtmlEditCtrl control and load your text to it with SetDocumentHTML(LPCTSTR) method and then call PrintDocument() method.

void WaitForComplete(IHTMLDocument2* document)
{
    BSTR ready;
    document->get_readyState(&ready);
    while(wcscmp(ready, L"complete"))
    {
        AfxPumpMessage();
        document->get_readyState(&ready);
    };
}

void CPrintInMFCDialogBasedAppDlg::OnBnClickedPrint()
{
    CHtmlEditCtrl PrintCtrl;
    if(!PrintCtrl.Create(NULL, WS_CHILD, CRect(0, 0, 0, 0), this, 1))
    {
        ASSERT(FALSE);
        return; // Error!
    }
    CComPtr<IHTMLDocument2> document;
    PrintCtrl.GetDocument(&document);
    WaitForComplete(document);
    PrintCtrl.SetDocumentHTML(_T("Hello!<BR>It is <B>my first</B> print!"));
    WaitForComplete(document);
    PrintCtrl.PrintDocument();
}
