You need to provide more details; it is impossible to guess what is happening.

I use a PieChart class, to draw in my dialog..if I add in InitInstance this code:
Gdiplus::GdiplusStartupInput gdiplusStartupInput;
Gdiplus::GdiplusStartup(&m_gdiplusToken, &gdiplusStartupInput, NULL);

the second dialog that must open when I press button on my dialog doesn't open.
