Hi,
I've made a CustomPanel derived from the Panel class.
How can I set my own size of the "client area" of that CustomPanel ?
("client area" = Size of the rectangle in which one can drop controls from
the toolbox, or place a control by code)
Because of the large border, some control too close of the border are on
top the border. I would like to prevent user to drop control where the
border is drawn.
Thanks for help !
Steph.

You would have to override the WndProc method in your derived class and
handle the WM_NCCALCSIZE (0x83) message.
I haven't evaluated the entire code base; but, the CodeProject project
Themed RichTextBox ( http://www.codeproject.com/cs/miscct...hTextBoxEx.asp)
is an example of doing this.

Thanks for your reply and the Link !
I have another question :
Except very simple controls like aggregate of existing controls and
"client area painting", what is the best way to make CustomControl to be
used in .NET ? Is it to make it in C++ and then write a wrapper class in
..NET ?

You can write custom controls in any .NET language you like--which is what
I'd recommend if you want to consume then in a .NET application.
If you want to aggregate one or more existing controls then I suggest
deriving from UserControl.
If you want to create a control that performs painting entirely itself, I
suggest deriving from Control. Or Button, if you want to handle mouse
clicks--it makes life a little easier.

Hi , when I apply expression on a pure HTML control , like<img src=<%$
resources:...% > , I got a compilation error and said this is not allowed
,after I add "runat=server", the problem is fixed.But it's kind of ugly since
it will unnecessarily consume some of CPU cycles to process in the asp.net
engine. I'm not sure if there is a way to get it work?
Appreciate any help.

Hi All,
In web page, we can make a HTML Area text box for user to input content
(e.g. text, font size, picture) and switch to HTML code with some WYSIWYG
control.
I am writing a VB.NET windows form application that need to have a similar
HTML Area that can input content or switch to view HTML code. I think this
can make use of Rich Text Box, but are there any sample source code for
using or any control available in market to buy??

Hello,
I was wondering if there was a way around leader-alignment. XSF V3.4
from Antenna House seems to be a very powerful FO -> PDF converter, but
it doesn't support this particular attribute from fo:leader. It doesn't
support leader-pattern-width either but this can be bypassed by using
leader-pattern="use-content" as such:
<fo:leader leader-pattern="use-content"> . </fo:leader>
