there are lots of similarities; a nice difference is the outline you get for free.
reading MSDN will make you discover all the differences.

Head on over to the DevExpress forums and Support departments ASAP then. They're very good at answering questions about their products.

i wrote the following code at the form load
ArrayList s;
it showed the following error
The type or namespace name 'ArrayList' could not be found (are you missing a using directive or an assembly reference?)
is there any dependency or namespace i have to include.

hi sonia
ArratList? or ArrayList?
regards
|
|
|
|

Because it should be ArrayList instead. There is no ArratList in any of the standard namespaces (I can't speak for any assemblies you've written here). The ArrayList is in the System.Collections namespace.

It's ArrayList not ArratList.
Also, you need to reference the System.Collections namespace in a using statement, or fully qualify the type, eg: System.Collections.ArrayList.

This line will not compile (and im sure you didnt want an Array of 100 ArrayLists)

For all Framework classes MSDN states to what namespace they belong.

I'm looking or a neat way to draw all over the top level form of my application. I have a MDI form that contains a split container control and a variable number of child forms. I want to draw using GDI over the whole area of the form. I can do this using DrawReversibleLine but while it is adequate it is not ever so elegant and can draw in the wrong place - I could program some more to stop it doing this but I was looking for a way of using c# and gdi to draw over the whole of the form or for that matter, on any control or region.
My bit of code looks like this:
Graphics gg = this.splitContainer1.Panel2.CreateGraphics();
Pen pp = new Pen(Color.DarkTurquoise, 1);
this.Show();
gg.DrawEllipse(pp, 30, 10, 70, 50);
It draws an ellipse in panel2 of the split container and of course cannot draw anything outside of it. I want to be able to draw either over the whole split container (say) or over the whole form.
What are my chances?
Kind Regards,
Andrew Parsons.

If you want to draw on the form, use the form's Paint handler.

Hello Luc!
I think his problem is that it will not draw his painting over(z-Order) the Controls which are placed on the Form.
Or is there a way todo so?
I once had this problem, and endet up placing an Transparent Form on top, which does the painting.
All the best,
Martin

Hi Martin,
I don't know what the z-order would be of existing controls and the form's own ink.
And frankly I don't care, I never paint on a Foem, I paint on a Panel, and yes if
the requirement would be to paint over existing controls, I would add a disabled
and transparant Panel in front of everything (not another Form! I try to keep things simple)

Has nothing todo with form's ink, off corse!

It depends on the task, if this statement is valid or not, I guess.

Thanks for the replies. I'm still working on it and making some progress. If I use DrawReversibleLine which draws a nice clean line down the form over everything as I want I get a problem with it painting over other windows. This happens especially when it is partially covered by other windows and they move. My application draws a moving line that is triggered by a clock tick. At the moment I am going down the path of using DrawLine. This however will require a pretty full repaint every time the pointer moves, it will however behave properly as far as Windows is concerned.
DrawReversibleLine takes screen coordinates and will draw a line on the screen using the coordinates you give it regardless of any windows that might be partially obscuring yours. I really need the extents of the unobscured window so I can give DrawReversibleLine coordinates that only fall within the visible window. Am looking at GetUpdateRect at the moment to see what that will give me.
