Hi,
Sorry for the late reply
I am developing a User Control that display on a ASPX page. there I
developed a class object (typically called as c# applet) and add it to the
html manullly using the object tag.
I use c# and won't heart if you are using vb, I guess.
I have a one Object class that extends a UserControl and there I have
override the OnPaintBackGround to get the object transperency. and All the
lines Circle and Rect are extended objects of the Object class. For the main
drawing board (drawing area) I use a panel. There I am using a dynamic
bitmap image as well, that is as a background image of the main drawing
baord for avoiding periodic refreshing.. so since you have already started
this I think this note will help you to get some idea..

Sorry i'm not here to answer you question, but instead...I need to get
some help from you!! =P Are you developing a WindowsForm or a WebForm?? I need to create this

Hi,
I want to create drawing board application that can draw Line,
rectagle, circle and free hand drawing.
Each drawing need to be transparent, moveable (draggable), have bring
to front and send to back feature etc.
How can I do this .. where should I start?
Right now I have used a panel as the drawing board and each of the
drawing object (line, circle etc) as user controls overriding the
OnPaintBackGround. the user control draw on the board upon variuos mouse events as
appropriate. But I fail to acheive the transparency. What is the best way to do
this?? I mean if I drew a rectangle I draw rectagle (not a filled one) in the
user control and add it to the main drawing board but then it just make a
white rectangle hiding all the other drwing comes under the new rectangle.
Get me a direction if I am doing some thing wrong and If I am doing
it correct what I have missing??
Thanks,
Regards,
Nirosh.
