Drawing an arrow
-
Hi, I'm trying to draw an arrow in a DC. i have a line, consisting of the starting point(aa) and the ending point(bb). (CPoint variables) I do a Moveto (aa) and then a LineTo (bb). What i want to do, is like a triangle, the end of an arrow (or just two lines), but i haven't came up with ideas. The problem is that the line can be in any direction, not just horizontal or vertical. how could i do that with just aa and bb(the start and end of the line)?? thanks!!

If you want to use GDI+ you can use the Pen::SetStartCap() and Pen::SetEndCap() functions to have GDI+ draw the arrow heads for you. AFAIK, with GDI you have calculate and draw the arrow heads yourself.

yes, which is explained in this article on codeproject http://www.codeproject.com/vcpp/gdiplus/startinggdiplus.asp[^] which you can find by doing a Google search. You will find that productivity in software development is directly related to your ability to search for, read and understand documentation, articles and examples... even the bad ones :-D
