is there a way I can dynamically draw pictures in C#, for example I have a program its does some stuff, and based on the result I wanna draw a box or a sphere. what would be the best method to draw this.
The System.Drawing namespace (GDI+) has a buttload of stuff that allows all sorts of flexible drawing. To use this stuff, you need to get a Graphics object, which is most easily obtained from a System.Windows.Forms.Control object using the CreateGraphics() method. Using the Graphics object, you can call various Draw* methods to draw lines, curves, filled shapes, and images. The documentation should contain a wealth of information for you to browse.
You can use the Graphics class in the .NET framework to draw boxes and stuff. You could even use the GDI extensions. SDL.NET uses SDL_gfx for primitive drawing.

theres not Convert.Tofloat(value)
is it possible to do that?

Yes, it's an explicit conversion:
double val1 = 5;float val2 = (float)val1;I tried it in C# to make sure it works before hand [wink] That should do it. For more information on that nonsense in C#, look at this MSDN page. It can get quite confusing at times when you need a function to go between types or just a typecast.

You're looking for Convert.ToSingle(value). A float is a "single precision floating point" variable. But it just gives you the same result as what Drew_Benton posted, so you should really use that instead.
