GDI to DirectX

[Ricardo Furtado]

I use GDI+ in my application, with visual basic .net 2005 , but now that im
trying to create new functionalities, i'm using DirectX and Visual C#. I've
encountered a big problem. The application is a medical application where the
doctor has to click, with the mouse, in certain parts of an image. Those
clicks will create points that the program will save in a database in order
to later display them on screen. When i use directx and visual c#, the points
aren't shown in their correct location. The points are a lot close together
and in different locations. In GDI i was drawing on a picturebox and now i'm
just drawing in a black screen. I've already summed (+) then picturebox.left
and picturebox.top, but even that didn't work. the picturebox was drawing
in pixels. Could directx be drawing in another measure?

Can you please help?

My thanks in advanced

Ricardo,
I'm only just starting off moving from GDI+ to Managed DirectX so
have been running into lots of problems. I've been looking at this
program as a tutorial and I think it may meet your requirement. It
does more than I think you want, but it does allow the user to click
on the screen and add points where the click occurred. It Download the
DirectX.Zip file at the following location http://www.public.iastate.edu/~andrewv/directx/

I hope this helps.
