I believe I have found a severe limitation of DotNet, with respect to
hosting Windows Form Controls in WebPages.
It appears this is only possible when the web is configured on Port 80. Any
other port and the control will not display.
After a couple of days of searching the newsgroups/various forums I have
found other postings requesting information on this anomaly yet nobody has
found a solution.
What are Microsoft doing with this ? It seems a common situation to run on
alternate ports, being restricted to the default 80 seems ludicrous.

hope you do realize that there is a reason why they are called windows form controls, not fancier web form controls. you are doing something that's not *officially* supported by Microsoft. If there's truly no solution, tough luck, it was never meant to work in the first place.

Hi when I set it to Scripts and Executables, its definately a no-go..
Even when running on port 80, it has to be set to Scripts Only. When
otherwise the control wont show.

Actually, hosting WinForms controls in Internet Explorer is not only
supported but encouraged by Microsoft.

I'm not near a webserver at the moment so can't try this out, but it may be
because you are using unsigned controls
and the .net securty is saying hold on a second you don't have rights to run
this from a dodgy port. You could
try making it a signed control and creating a new security group in the .net
frameowrk that allows everything
and see what it does.
Try looking for an article called
DHTML and .NET: Host Secure, Lighweight Client-side controls in internet
explorer
in the msdn. Will give you more details.
As I said not near a web server to be able to try this out at the moment but
hope it helps.

Ahhh, I think I might be getting somewhere....
Forget about IIS error logs or the event viewer, Error reports are created
in the temporary internet files folder containing detailed information about
why the .NET files failed to load properly..... It does look like a
security/permissions problem, so running on a different port gives it
problems....

A useful tool for this is
fuslogvw.exe
if you go to the command prompt(probably the visual studio one unless you've
setup the paths correctly and just type
fuslogvw this will bring up this little app and will allow you see any
errors that occur)
Though it does have a Log failures check box I find you need to set a
registry key to get it to be really useful and
see everything that's going on.
To log all binds in the viewer
a.. Set the HKLM\Software\Microsoft\Fusion\ForceLog registry value to 1
(the value is a DWORD).
By default, Fuslogvw.exe only logs failed attempts to locate assemblies. You
might have a situation where it is useful to view all successful assembly
binds. For example, you might want to verify that an assembly is loading
from your application directory
Check out the article http://msdn.microsoft.com/library/de...uslogvwexe.asp
by the way that log report does look like it's a security permission failure
so signing it may work. Though be prepared to spend
time getting it to work correctly (and getting very frustrated into the
bargain as well)
