RE: "The system cannot find the file specified" appears peridically in runtime

Steven Cheng[MSFT] · Jan 4, 2006

Hi Ofer,

Welcome to ASPNET newsgroup.
From the error info you provided, seems the occur is caused by the page
failed to load the assembly of a certain ascx usercontrol. Is the
<pix:xxxxx ...> the usercontrol? Also, does the problem always occur on
that particular page and the referenced usercontrol? If so, would you
provide the position of the page and usercontrol in your website
application's folder structure (in the same directory or not ....).

Based on my experience, such assembly not found error may caused by the new
different compilation model, when the referenced ascx control is not put in
the same directory with the page that use it, the classes(page class and
the usercontrol's class) may be compiled into different dynamic generated
assembly which cause control reference not found..... Also, is your
usercontrol derived from another ascx usercontrol in the application? If
so, this is also the possible cause, since the base ascx control's class
maybe compiled in to different assembly.
If this is the problem, you can try explicitly add the following directive
in page's aspx to reference the usercontrol(or base usercontrol) so that
the usercontrol's code will be compiled into the same assembly with the
page:

<%@ Reference Control="~/UserControls/WebUserControl.ascx" %>

If there're anything I didn't quite get or any other finding, please feel
free to post here.

Thank you so much for your answer. I'm sorry for the late response, I wasn't
"online" in the last week.

As for your questions - pix

ispOfficeMajor is indeed the usercontrol. The
error occurs on different pages that use/call this control, and as noted
before - the control (and the whole project) is perfectly compiled.
An interesting point is the directory structure. The website consists of
"public" part, root folder of the website - in which that control resides,
and a backoffice part. As you can see, according to the error report, the
page that threw the error resides inside the BackOffice folder - which is
NOT a virtual directory nor contains a Web.config file. The only means of
difference of the BackOffice folder are in the main site's Web.config file,
where Forms Authentication definition tags refer to it as this folder
(BackOffice) requires authentication (as opposed to the root folder which is
a public web site).
Anyway, I don't think that the above site structure raises the error, since
as I said - a stop-start action on IIS fixes it.

As for your second suggestion - Reference problem. That sounds like a
possible option for the problem. But:
1. The control is called by different ASPX pages. Does each one of them
have to contain the <%@ Reference %> tag? If so - would the control be
compiled with each one of them separately?
2. In any case, as noted - Stop-Start on IIS fixes the issue, so I doubt
if an explicit <%@ Reference %> tag would make the difference. I can't
reproduct the problem (it just happens from time to time) so I can't check
with and without the <%@ Reference %> tag to see if that maked the
difference...
Note - the control is not inherited from another user control.

I'll be glad to get an advise for further suggestions....

Best Regards,
Ofer

Seems a bit different than I've expected. Is it possible that you provide
me a simplified test project with a page and the necessary simplified
usercontrols so that I can test on my local side?

Thanks,

I'm afraid that it would be very complicated to create a test project...
which should resemble as much as possible from our full project (that's
because we can't pinpoint the cause) and on the other hand be "naked"...
