Hi,

Sorry for my Question, but I try to port the Charting Demo to VB.net. I have problems to understood the line

Code:

this.pagePreview.SetRenderEvent(new PagePreview.RenderEvent(chartFrame.Draw));

I dont know this kind of call.
Have anybody a simple demo to implement this event in vb?

Thanks fidibus

new creates a new, unnamed object.
An Event is a "function pointer". This call specifies which method is used to render (i. e. draw) something.

I dunno how to write this in VB. In VB you can use DIM to create a new, named object IIRC.

Hi Thomas,

thanks to your answer! Unfortunately, I have no solution for this problem. But I can realize my project without a pagepreview.
If have enough time, i will search for the solution and post it here.

Thanks Fidibus
