drawing in a view from a dialog

[markitus]

hello, i must make a program that must let me draw a rectangle, a line or a triangle. For choosing the figure i want, i must use a modal dialog, by selecting a radio button. Well, once i select in the dialog the figure i'd like to draw.. how can i access from here to the view so it will be able to draw what i want? i know it's a simple question, but i'm just a beginner.

void fig_dialog::OnRectangle() 
{
 ....

}

i know how to draw if i do it directly from the view file.

	MoveToEx( hdc, a.x, a.y, NULL );
					LineTo( hdc, prev_b.x, a.y );
					MoveToEx( hdc, a.x, a.y, NULL );
					LineTo( hdc, a.x, prev_b.y );
					MoveToEx( hdc, a.x, prev_b.y, NULL );
					LineTo( hdc, prev_b.x, prev_b.y );
					MoveToEx( hdc, b.x, a.y, NULL );
					LineTo( hdc, prev_b.x, prev_b.y );

how could i access to the view file??

Hi,
You can use it very easily. Within the function which you want to draw get the DC by using the following function
CDC *pDC = (CDC *) GetDC();
then draw/write anything usiing the DC as shown below
pDC->LineTo(100,100);
Hope this may help you
