Hi Jamal,
I tried to mail you privately some days ago about my problems with Lbc, but
maybe I didn't get your mail address correct. Since someone asked us to keep
the discussion on the list, I guess it would be ok to do so anyway.
Ok, here is what I have found until now:
Apparently, the "invalid cast" exception is only thrown when the program is
run from inside the debugging environment of VS (f5), not if you run without
debugging (ctrl-f5) or if you run the exe file from explorer. I enclosed the
whole thing in a try / catch statement to make sure I was handling the
exception if it ever turned up, but it didn't.
I was able to trace the exception to the complete() method. I then had some
difficulty finding my way around the code of that method. However, one line
did catch my attention:
var frm: LbcForm = Form.ActiveForm
I am definitly no JS expert, but it seems to me that you make that
assignment before loading and showing the form, and thus before it has
become active. I can't tell why it works in one situation and not in the
other or if it has anything to do with the case at all.
Maybe, if you could provide me with a debug version of the dll, perhaps I
could track the exception down further.
Hope this brings us nearer to a solution
Best regards
Bue

Hi Jamal,
Thanks for the reply. I will try what you have mentioned. I then suggest
that we move the discussion off the list, so we don't make too much noice.
I am still very interested in knowing how everybody else on the list is
making a gui with a decent layout, Windows forms or not. You can't mean to
tell me that you are all stuck with making command line driven console apps
:-)
Best regards
Bue

Hi,
I use a text editor rather than Visual Studio for .NET development, so was
hoping that someone else might have a solution to the problem you
experienced compiling with Homer.NET. As its author, I would like to work
with you to resolve the problem. If possible, please try the following and
report yur results.
I think there is a way that VS hosts a program that is under development,
rather than launching that program to run independently. I am not sure, but
think that is where the problem is arising. Can you compile the code and
run it without this hosting scenario? For example, I vaguely recall that
Control+F5 compiles, whereas F5 runs a program in a hosted mode. If
compiling is successful, then try running the program outside of VS, or look
for menu options on a project or build menu that allow you to run the
program independently (not hosted for debugging, etc.).
If that does not work, try compiling from the command line with the C#
compiler, csc.exe. There is a VS Start Menu option for opening a console
mode environment that sets appropriate paths to the command line compilers.
You will need to reference assemblies as appropriate when calling the
compiler. the batch files distributed with Homer.NET illustrate how this
may be done.
I realize that you may prefer to use VS for everything rather than a
command-line compiler for some tasks. This would help us identify where the
problem lies.
