Designer stuck in loop

We have a window named FormApplication which just happens to be our
mid parent window. When I open it in the designer, it is stuck in a
loop redisplaying a c1flexgrid. maxing out our cpu's. By attaching to
the process from another visual studio, I can get it to break on some
user code with this huge callstack, most of which is native. So are we
instantiating something in design mode that we should not be? Does
this mean anything to anyone? Is there any way to track dow the cause
of this?

That would be mdi parent of course...
 
Hi Tom -

Do you have anything specified in the form's constructor? This code
will be run when the form is loaded in the designer. If so, that may
be the cause of your loops.

Cheers,

Mark,

The window itself doesn't even have constructor sub other than what
happens in the designer written code. We do have a couple of instance
variables that are declared and instantiated such as an arraylist and
booleans.

Thanks,

Tom
 
Do you have any custom controls on the form which may be attempting to
run code in their constructors or OnLoad event handlers?

Thanks,

-Mark
 
Actually, when we're talking about custom controls, they are
essentially running inside of the designer; so any code that responds
to mouse movement, etc, may be running as well.

Thanks,

I just have no idea how to find it, if there is offending code
executing. We have 1 custom class on the window, a c1flexgrid, with 4
instances. Now this class is inherited by the window project from yet
another library that inherits from c1 but both of these contstructors
do little more than assign some boolean values. We have numerous
instances of this same control on other windows and it causes
absolutely no problems elsewhere.

I have a debug session running against the designer and it just runs
until I do a break all and then f10 and it steps into some user code
in our flexgrid library code and our flexgrid windows code but I don't
seen any calls other than native code so don't know any other way to
examine this.

Any ideas how I can find the offending code short of a lashing?

Tom
 
It's kind of hard to determine when I'm not looking at it...

Naturally, you can start asking yourself question such as:

What is different about this form and the ones the control is working
on?
Does this control support having multiple versions on one form/is
there any reason why it might not allow that?

....and if all else fails, you can start commenting out blocks of code
until you get it to work, and narrow down the problem that way...but
man, that's a brutal way to proceed.

When you do find the problem, there are code samples online (albeit,
buggy ones) that will return a boolean value indicating whether or not
you're in the designer. (I'm surprised there's nothing in the
framework for this by now.) You could wrap the code in that function,
or, ideally, rework your solution to avoid whatever pitfall you came
across.

I had a similar problem recently with an inherited form that behaved
irratically inside the designer. I chose to rework the solution,
because the aforementioned function only works due to a bug that will
hopefully be resolved soon.

Good luck, Tom,

I've asked myself several questions, some of them not very polite, but
I keep getting the same dumb answers (from myself). If anyone has any
other suggestions, I am all ears.
 
create a backup of the form...
open it ...
delete the grids from the form.
add them back one by one - closing / opening form in between each
re-link any code to the control.

i know this is drastic, but it will either bring the problem to the surface
or simply make the problem disappear. just be sure to backup your current
form.

Have you bound one or more of the C1FlexGrid Controls to a Database
using the "DataSource" property in the Design Window? If so, try
releasing this and see what happens.

Also, I think you wrote that you haven't generated any code as yet, so
try removing the "ToolStrip" control that shows in the CallStack, I've
had a problem with this failing to initialize in the past.

(Just my 2-cents worth!)

There are 10 kinds of people - Those who understand Binary and those who
don't.

Problem solved. Turned out to be some bad references that must have
been causing a conflict.
