Hi,
After using an assembly compiled into a DLL and added to the assembly
cache for several months, we decided that it was too much trouble to
maintain because of all the steps involved with every minor change
(e.g. making the change, compiling, uploading the dll to the
production server, opening vnc and running gacutil, etc...). I have 2
questions associated with the problem, and depending on the answers,
we'll decide what's best:
1- Is there a way to unload the assembly from memory without
restarting the server? From our experience, the only way we found for
updating an assembly in the assembly cache is to restart the machine,
otherwise, the assembly seems to stay in memory and the new dll file
with the modifications is not taken into account.
2- If we move all the dll source code into a single .vb file, is there
a way to access the classes from codebehind? <% Assembly src... %>
does not seem to work for that, the classes being accessible only in
the aspx page and not in the aspx.vb code... With the dll in the
assembly cache, we only had to use Import statement. How do you do
"Import" classes from a .vb file?
Thanx for any useful infos!

depends on the OS of the server.
With 2003 you can flush the app pool or restart the SITE as well.

Some thoughts:
You can unload an AppDomain, but you cannot unload an Assembly within an AppDomain. This means that
all of the objects you get out of your Assembly will need to be Serializable since they cross domain
boundaries.
Here's an idea I had a while back, but haven't had the chance to think about further: You could put
that .dll in some folder on the server. Then you could have a Windows Service app that monitors the
file for changes; when there's a change, have it load the file into the GAC for you.
Windows Explorer supports "drag-n-drop" install into the GAC; go do c:\<windows dir>\Assembly\ and
drop the file in. This *does* work over NetBios too, so you can install on a remote box if you don't
mind using that.
I'm unsure about what you mean in #2. You have to add that dll to the "References " section of your
project anyhow or it won't compile. If you just move all the code to the same project, you're done.
If you're going to do that, why not just remove the thing from the GAC entirely and just drop it in
the same directory as the app? (Less things to change/break)

I'm working on a Windows forms/C# database application. My background is
6-7 years of VB 4 - 6, MS Access, VC++, mixed in with a lot of T-SQL and MS

Previously, I haven't been overly impressed with the capabilities of the

Though deceptively simple to get started with, IMHO they haven't provided

Hi There!
I'm having trouble dynamically adding custom controls. My custom controls
does not use code-behind but only <script /> block for programming. So as a
result, I don't need to compile my custom controls to dll for them to work.
But I wonder, if I don't compile to dll, can I still dynamically add that
custom control? If so how? Below is how I've tried (and failed).

I am messing around with Web User Controls at present and (think) I have
discovered the following.
1.) The identifier for the control in the code behind must match the ID for
the control on the page.
2.) The identifier must be delcared with a minimum access of 'Protected' in
order to work.
If the above is indeed correct, then I have made the following assumptions

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
