2nd Prob - Error Design Time Html

[Mythran]

We have a web control. (Please note, all our libraries and controls are given a
strong name). When we place the web control on a web page, it works fine. We
are using a project reference to it in our sample application. Sometimes
immediately following a build/rebuild, it displays the design time error html.
We have tracked the problem down to the first line in GetErrorDesignT imeHtml() (I
believe that's the method's name, I just woke up). That line is Dim ourObj As
OurObject = DirectCast(comp onent, OurObject).

The exception message given is along the lines of "invalid type cast". Now, how
is "Dim a As b = DirectCast(c, b)" when c is passed into the routine as follows?:
Public Sub GetSomething(By Val c As b) Just doesn't make sense to me.

Note: I have found that when I do a build, the exe can't be overridden (it shows
up in the task list when I build but is removed just as fast). I have to build
over and over in order to make out which file can't be over-written. The
permissions are not an issue. I believe vstudio is over-writing a file that it
has locked between builds but can't be sure....

Any help is appreciated,

Thanks,

Mythran

Why do you need to cast c at all as you already did this casting in the
function signature, you probably are not passing the right type to the
function at run time.

I don't see any reason for using 'DirectCast' in this situation. What
about removing the 'DirectCast'?

lol sorry...

The original function is the overridden function GetDesignTimeHt ml(ByVal
component As Object).

I am not passing component, the framework is ;)

After more testing I found that component (the object) is the previous
version of the component loaded (using the designer). I checked the
references but they are all project references...so that doesn't help me
much (solving the prob). So, any more suggestions?

Thanks,
