Hi Teddy,
I had been out of the loop for several years when I started programming
with
Bill Dennis's Blind Geeks. The VS interface was like very easy to use. It
helped me a lot especially when it came to intellesense and form layout.
How would you like to go back to "Edlin" and a paper manual?
Sorry if you don't like exactly what it does, but I will not agree that it
is useless.
.
Regards,
James

Aha, so I am not wrong when I say that actually, VS.net is pretty useless
for the blind?
Again, if we don't consider Intelisense, of course.

Example of nested layout panels and dynamic form creation
Public domain by Jamal Mazrui

Here is an example of using nested layout panels of the .NET Framework.
Note that no pixel coordinates are used for positioning and sizing
controls. The form, TableLayoutPanel, FlowLayoutPanels, and Buttons are
all laid out automatically according to defaults and need.
I wrote and compiled this C# code with EdSharp and the command-line
compiler. Although Visual Studio certainly has its benefits, I think
significantly more time, effort, and code would probably be involved to
do
the same thing with the form designer, code generator, and multiple files
of a Visual Studio project.
Below is the source code of LayoutPanels.cs, which is also included with
the compiled version, LayoutPanels.exe in the archive available at
http://EmpowermentZone.com/LayoutPanels.zip
When the executable is run, it calls a function called MultiInput that I
have found useful in various contexts. It presents a dialog with a
number
of edit boxes determined at runtime. Parameters to the function provide
the dialog title as a string, and the labels and default values of each
field in arrays. The function returns an array with values as edited by
the user, or an empty array if the dialog is canceled. The program shows
those return values in a message box.
