RE: Problem with WinForms User Control Hosted in IE

Tech-Archive recommends: Speed Up your PC by fixing your registry

Thanks for your response Seg,

Yes, the bin dir is a particular directory which is used by asp.net
application to store application assemblies, so by default it should not be
public to internet(so no read permission is granted), I'm not sure whether
the IDE or extension will automatically reset it to non-read... However, we
recommend that you put IE hosted control's assemblies in another sub
virtual directory in the application directory since they're not part of
the asp.net application's assemblies (just used by the IE hosted controls
which is running at clientside....)

| Hi Steven,
|
| Thank you for the reply.
|
| Yes. That is kind of what's going on. If I enter debugging mode in my
VS
| .Net project, it doesn't see the DLL in the bin directory. If I then
manually
| go in and set the bin dir to read, then my web page can access the DLL.
| However, as soon as I stop debugging and start again, the bin directory
has
| been reset to not-readable.
|
| What was happing a couple days ago, and I think it had something to do
with
| the server extensions, is that it wouldn't reset the bin directory to
| not-readable each time, so, as a result, the bin directory is readable
when I
| step into debug mode, and I'm able to debug my winform control. I thought
| that was pretty convenient.
|
| I'm still investigating. Is there a good reference on the server
extensions
| and that the following files control, do you know:
| _vti_cnf
| _vti_pvt
| _vti_script
| _vti_txt
|
| and inside the _vti_pvt folder I see the following files which I'd like
to
| get more info on.
| access
| deptodoc.btr
| doctodep.btr
| service
| service.lck
| services
|
| If you don't know right off the top of your head, don't worry about it,
I'm
| in the process of googling it now.
|
| thanks,
|
