Hi, I've created a very simple winforms control using the c# wizard in VS .net 2003 that is nothing but a System.Windows.Forms.UserControl. There are no other controls on the form
It takes IE 12 seconds to load this control into the page. CPU usage is at only 1% to 2% during the 12 sec
All of this is on a single machine
XP Pro sp1 (all critical updates loaded)
2.6GHz, P4, 512MB ra
IE v6.0.2800.1106.xpsp2.030422-1633
IIS 5.1
..net framework 1.1.4322.573 (my computer, intranet security set to "Full Trust"
Here is the html page I use to load it
<html><body><object id="SlowLoad1" classid="http:SlowLoad1.dll#SlowLoad1.UserControl1 " height="500" width="500" VIEWASTEXT></object></body></html
The real control I'm trying to build takes over 40 seconds to load. I'm finding that it hangs when calling ResourceManager functions that load an imagelist, but finally it does load, and work once loaded
Worth noting that before running the test
- I cleared out everything under my user account\VSWebCach
- Removed everything under C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Tempo rary ASP.NET File
- killed (auto restarted) aspnet_wp.ex
Here is a dump of the gac and dll loading when launching the web app from VS .net
Auto-attach to process '[2396] aspnet_wp.exe' on machine 'JJAHOME' succeeded

I believe this to be a server side issue because I've tried with various other remote client machines and I get the same results.
Any help to resolve this would be appreciated.

your timing's seems about right, actually kinda quick. for IE to host a
WinForm control, it has to load the .net runtime, create an appdomain to
host the control, download the code, jit and load it. Your 40 seconds also
seems right for a control of any complexity. You can proably get the 40
seconds back down to about 12 seconds by preinstalling it in the GAC.
If you want to use controls with IE, you should really should stick with
true active/x controls.

Bruce,
Thanks for the reply. The thing is, when I build our real control into a
local winforms App and launch it, 40 seconds becomes 2. My guess is that
IE must be doing lot's of security stuff before allowing the control to
run.
I think I'm going to explore a Smart Client based solution instead of
going back to Active-X
