Thanks a lot for reply,
The foundation of my project is using object drawing model in IDL's
IDLDrawWidget control 3.0.

At first,The PolyLines can be connected using LineStyle value eq 2 or 3
and without using *coord_conv in 'IDLgrPolyLine'.But ,the Symbols can't
be seen.I don't konw WHY it is.

The Second, VB、VC etc. must use axIDLDrawWidget1.DrawID as draw
id;But,C# can use IDLDrawWidget1 as draw id directly,I have filfulled
it.The world map can be draw corretly.
But,the communication mechanism seems changed.I can use GetNamedData or
CopyNamedArray to get variable value from IDL in DIRECT DRAWING
MODEL,And now ,I must use SetOutputWnd to get the IDL's value in OBJECT
DRAWING MODEL.

My quesion is:
1. I have filfull the background map drawing,using the IDLgrPolyLine
and the data source is *.shp,I want to overlay some symbols to this
background map,the polylines can be drawn,but the symbols can't be
drawn.

2. Are there a good method to get variable value from IDL 's Object
program model in C# environment.And now ,I use SetOutputWnd but not
GetNamedData.

Can everyone help me!
