Do you want to draw the chart, or also be able to edit it, and have it change it's values accordingly ?

Either way, I don't know of any controls, but drawing one shouldn't be that hard.

Thanks so much for the speedy reply. As of this time, I wont venture yet into editing the chart but maybe later on. I just want to make a start, drawing it so to speak. Could you help me on this? I really really appreciate your time.

Thanks! Smile | :)

Actually, I reckon you just need to create one or two owner drawn cell types and use a datagrid ?

Hello,

I've been trying to convert a simple USB control program from VB to C#.net for a past few days and I'm making no headway. Can anyone help? The original program is at

http://www.devasys.com/release.htm

Its at the bottom of the page, along with a C++ example.

Much thanks.

Which bit is causing you grief ? The easiest way out is to write a managed C++ wrapper around this C++ code and call that from C#.

I'm new to the entire "wrapper" concept. I'm currently experimenting by using the dllimport function in C#. Will a managed C++ wrapper be easier?

dllimport is pretty straightforward, but what I'm talking about is creating a managed C++ dll project, which exposes the functionality you want from the C++ source, and then using that dll in C#. I've done it a few times, it's pretty trivial.

I agree with this methodology. Exposing it as a 'native .NET' assembly is far better than managing and maintaining the exporting of methods from a Windows DLL in C++. Either way you will have to maintain an interface, why not just do it in one place.

I'll poke around to see what i can figure out. Do you have any past projects you might be able to e-mail me to give me an idea of what to do?

There's nothing you really need, just create a managed dll, and you've got a project that you can write in c++, but which can be called from C#. Then you just add methods to your managed class that expose the methods you want to call. You create an instance of the internal class within the managed one, and pass the methods on to that.

VB to C# is automated via numerous VB to C# conversion utilities (but C++ to C# can't be automated).
If the program is small as you say, then the demo edition of our Instant C# VB to C# converter may be all you need.

Hi David. If you followed the link, he has a VB6 app he wants to convert.
