MSChart image printing VC program processing:
In VC, implementation of printing is much difficult than in VB, in such a question, VB's solution is simple:
VB solution:
Principle: mschart.editcopy (copy control display image)
Printer.print Mschart.OpenClipboard (Interpretation of VB Statement) (Print Clipboard Content)
But in VC, printing is not an easy task, I put the source code for the MSChart control of the MSChart control in netizens, and give it to everyone,
Implementation,
HPALETTE HPALETTE; M_MSCHART.GETPLOT (). GetBackDrop () .Getfill (). Getbrush (). GetFillColor (). Set (255, 255, 255); m_mschart.getplot (). GetBackDrop (). GetShadow () .SetStyle (false); // Shadow
m_mschart.EditCopy (); if (OpenClipboard ()) // m_mschart {hDib = GetClipboardData (CF_DIB); hPalette = (HPALETTE) GetClipboardData (CF_PALETTE); CloseClipboard ();}. else return;. m_mschart.GetPlot () GetBackdrop ( . Getfill (). GetFillColor (). Set (192, 192, 192); m_mschart.get (). GetBackDrop (). Getshadow (). SetStyle (TRUE); // Shadow
