Hi,
I have a custom form that works fine when I debug it or run it in release
mode but cannot be loaded in the designer... Actually, it can be loaded in
the designer when no control is on it, but the resizing tool (in the
designer) is offset both horizontally and vertically and when I put a
control on it, as soon as I save, the designer throws an exception (but
cannot be reproduced everytime) and the form cannot be loaded anymore unless
I remove all the controls from it... but the major problem is the offset of
the designer... also, I'm unable to move the newly added controls on my
form... I can resize them when I add them and after that cannot even select
them... this behavior happens when I want to use the custom form (inherit
forms of my projects from this form)...

When I want to see the form in the designer (the CustomForm itself inherited
from system.windows.forms.form) I receive and exception too (here it is)

Events cannot be set on the object passed to the event binding service
because a site associated with the object could not be located.

Does anybody know the solution to this kind of behavior? btw, it may be
relevant to say I'm using a custom message filter (IMessageFilter)

Thanks

ok... great I solved most of my problems... the only thing remaining is
the fact that the form appears offset with the sizing anchors in the
designer when I inherit from it.

So let's say I have my CustomForm, then I create a form like this "public
class MyForm : CustomForm"... Everytime I want to load MyForm in the
designer, the anchors are offset... the form itself is in the right place,
but the anchors are offset low and right and everything I place on the form
is located at 0,0 and cannot be moved in the designer (cannot even be
selected again after I select anything else at creation)... I can move them
into the MyForm.designer.cs tought, and it works fine, but it's not the
"normal" behavior of things... does anybody can point me to some possible
causes for this problem?

thanks

Sorry for the slow response, but I've been busy.

Because you are using the method on my site, most users may not even have
seen the error without further info. I happen to know what you're doing
because of a previous thread.

When Inheriting the shapedform class you need to make sure that the
CreateParams is not applied in DesignTime, so the CreateParams method should
be modified as below:

protected override System.Windows.Forms.CreateParams CreateParams
{
get
{
CreateParams cp = base.CreateParams;
if (!this.DesignMode)
{
const int WS_CLIPCHILDREN = 0x2000000;
const int WS_MINIMIZEBOX = 0x20000;
//const int WS_MAXIMIZEBOX = 0x10000;
const int WS_SYSMENU = 0x80000;

const int CS_DBLCLKS = 0x8;
const int CS_DROPSHADOW = 0x20000;

int ClassFlags = CS_DBLCLKS;
int OSVER = Environment.OSVersion.Version.Major * 10;
OSVER += Environment.OSVersion.Version.Minor;
if (OSVER >= 51) ClassFlags = CS_DBLCLKS | CS_DROPSHADOW;

cp.Style = WS_CLIPCHILDREN | WS_MINIMIZEBOX | WS_SYSMENU;

cp.ClassStyle = ClassFlags;
}
return cp;
}
}

Great!!! everything is solved now... thanks a bunch... I modified your
solution a bit to remove the border at design time because, anyways, it's
not useful to show it as it will not be visible at runtime... and it does
not cause any problem to remove it at design time (no one I can see right
now, if you think of one, let me know)

Thanks a lot again!!

hi!!!

what did you do to get rid of the strange designtime error ?
i got the same problem after upgrading my project from .net 1.1 to 2.0.
all forms that uses my custom usercontrol get this message.
