I have found a solution using VB6 examples and news archive:
Dim hDC As Long
Dim DummyPt As PointAPI
hDC = GetDC(0)
Call SetPixelV(hDC, 100, 100, vbRed)
Call MoveToEx(hDC, 5, 15, DummyPt)
Call LineTo(hDC, 25, 15)
ReleaseDC 0, hDC
But instead a form it is plotting on Excel window itself (or on VBA editor).

Can anybody help? What parameter should I pass to GetDC() instead of 0?

Thank you in advance.

Mike.

Can anybody give an example or link of using GDI in Excel?
Is it possible to plot a function on a form surface for example without
Excel charts, just using LineTo, SetPixel etc.?

Thank you in advance.
