I have a pogram in VC++ 2008 made with Windows Forms that make a matematic function graph with the Zedgraph.dll how in examples, but I want now to show the data, while it is computing, to show data real time or minimal in dynamic form step by step. I know that there is an exmple in the wiki:

http://www.zedgraph.org/wiki/index.php?title=Display_Dynamic_or_Real-Time_Data[^]

but it has the example in C# and it includes a conversion that I can´t make run good in VC++ with the c# code:

LineItem curve = zedGraphControl1.GraphPane.CurveList[0] as LineItem;

and

IPointListEdit list = curve.Points as IPointListEdit;

and VC++ 2008 don´t have "as" operator and it generate 2 errors, this is only the problem.

Solution 1

Did you try casting the object by removing the as and placing it right after the equal sign?

Thaks! I have find the correct code for my problem and is this:

LineItem ^curve = dynamic_cast<LineItem ^>(zedGraphControl1->GraphPane->CurveList[0]);

And the other line:

IPointListEdit ^list = dynamic_cast <IPointListEdit^>(curve->Points);

All works good with "dynamic_cast" operator in C++
