Geometrics forms...

Hi,

I have to draw a geometric form quite complex, like a car for example.
Then, i need to know which part of the car the user has clicked on.

In vb6 i would have used the "shapes" component to draw the car and then use
a mathemtical formula to test if the user is in or out of the car.

In C#, i don't see any componant to draw geometric forms at design time.
Is there any ?
Is there a best solution in C# ?

Thanks !

I'd create user controls (or maybe only one for the whole car), override
OnPaint(..) and do the drawing myself. Most drawing functions are a
matter of calling _one_ function on the e.Graphics object, thus being
almost as simple as in VB6, yet much more flexible.

Also the GraphicsPath class contains a very useful function "IsVisible" .
It checks if a Point is contained within a specified area. So you can
easily check if the mouse is over even very complex shapes, without
doing at math at all.

Thanks for your answer but even if i understand quite well "the way to use"
graphic functions, i'm not sure to get how to draw the car.
Do you mean that i need to describe it by giving each point's coordinates in
the code ?

Is there any way to draw it directly with my mouse like with the paint
software of windows or like the Shapes componant in VB6 ?

Thanks again.

In my signature is a link to a commercial component that integrates in
Visual Studio .NET. It is much more than the Shapes component.

I can easily understand a newbie using bound controls or someone with a tight deadline. I guess I need...

Hi, I have a periodic problem which I am having a real time trying to sort. Background: An MDI VB app with a DB on SQL 2000. I have wrapped all the DB access into an object which spawns a thread to access the database and then displays a modal dialog which allows the user to cancel the task, if it is taking longer than they want, and shows them a display of how long the query has been running so far.
