Using VC++ and CFX98 COM DLL without user interface

Recommended Posts

In order to export Chart FX to an Image, you must first give it a size,

otherwise we wouldn't know what size of chart you want.

There are two ways of doing this:

i) Use the Creation method (in Chart FX) to create a chart Windows

previous to exporting the chart. This is the easiest but not the most


ii) Create a memory Device Context DC, attach a bitmap to it and use the

Paint method to draw the chart into that bitmap. Then take the bitmap

selected in the HDC and save it. This is the most efficient way but

involves a lot of Windows API manipulation.

Subject: Using VC++ and CFX98 COM DLL without user interface


I'm using CFX98 COM DLL with Visual C++.

I want to create a chart and export it as a bitmap file without

displaying it.

I tried the sample " Sample using VC++ and CFX98 COM DLL"

it creates a window and displays the chart and I can export the

chart in that example.

But how can i export the chart without attaching it to any dialog

or window ?
