add default processing to _all_ charts.

[User (Legacy)]

I'm using VC++ 6.0 

In ChartFX 3.0, I had some nifty default processing I added to every chart, 

wherein I would catch the mouse up and down events, and the mouse moving 

event, and along with the crosshairs, display the X and Y values as the user 

dragged the mouse.  Nice for checking points on curves, etc, etc.  I did 

this by writing a generic routine which took a chart handle, and the wParam 

and lParam codes from the WM_COMMAND message.  I stuck this procedure in a 

DLL, and just called it from any apps OnCommand message handler if I had 

charts in that window. 

I can't seem to figure out how to do this with ChartFX 98.  If I use the 

activeX events, I'd have to catch the events in every window that contained 

a chart.  Messy, and repetitive.  I can't seem to get the ICfxEvents class 

to work either, so if someone had a sample, I'd love to see it.   If I try 

to use the WM_COMMAND trick, I get all sorts of multiplied defined errors 

when I try to include chartfx.h, because I'm using the ActiveX stuff 

elsewhere in the app. 

Thanks,
