Releasing mouses grip on forms sizeable edge?

[What-a-Tool]

I have an mdichild form whose minimum size I want to limit (can't be dragged
below a certain size)
Even though I am running .NET 1.1 where the minimum size property supposedly
works, it's not working for my child forms.

Herfried K. Wagner directed me to a code sample which he wrote as a work
around for this problem.
Very interesting code. You're obviously light years ahead of me in
programing skills. Some day in the near future I plan on taking the time to
sit and check it out a bit more closely to try and undertand exactly what is
going on there. Right now though, I can't figure how to use it to get what I
want to happen. Thanks for the help though.

But for now-
Is it posible to get the mouse to release its grip on the edge of the form
as it's being dragged to a new size?
Have my form resize itself to my desired minimum size whenever it reaches my
min size, but the mouse retains its grip, enabling me to drag the form edge
around as small as I want. It always apears as my min size, but this just
causes it to flicker like crazy until you finally release the mouse button.
Can I force this release when my desired size is reached?

hi,

the Form_Resize event did nothing for you?

The only way I see (I still don't understand why the properties and the
"workaround " don't work on your machine) is to handle the form's
'Resize' event and reset the size whenever it is changed to a size
smaller/larger than the allowed minimum/maximum size.

Herfried -
Your work around does work on my system. I'm still trying to figure out how
it works, though, so I can apply it to my project. I just haven't had the
time to sit with it and figure it out yet though.
Like I said, it's very interesting code, and I think I might like to use it.

However, I had already started to solve this problem my own way before I was
given this other (admittedly better) solution, and now I am still wondering
if I could get it to work my way.

In my forms re-size event I call a procedure that checks to see if my form
is < its minimum size. If yes, I re-size it to my desired size.
So far so good.
However, if I fail to release the mouse button, it retains it's grip on the
location were my form edge should have been, and I can still drag this back
and forth, causing my form to flicker like crazy.
Can I get my mouse to release this grip rite after my resizing action?
Thank You

Would be interesting if the 'MinimumSize' property works on an other
machine...

and forth, causing my form to flicker like crazy.

That's the "drawback" of this method. Using 'MinimumSize' will prevent
the form from doing that. It's the only way to prevent the form from
doing that and it /should/ work (at least with .NET 1.1).

Hello:

I haven't done it yet on .NET, but in VB6 I used a timer to handle the resize event when it caused flicker.
Could be something like this:

'\\\
sub form_resize(... )
ResizeTimer.Int erval=300
ResizeTimer.Sta rt()
end sub

sub ResizeTimer_Tic k(...)
ResizeTimer.Sto p()
'Beep 'For testing...
'Put here the code you actually have on the Resize event.
end sub
'///

This code makes the resize event not to be launched (from the point of view of the user) until 0.3 seconds after the user stops (or pauses) the resizing of the form.
With this code in VB6, the timer's counter restarts each time the resize event is launched. I suppose it does the same under .NET.

Regards.

I think I discovered my problem.

Was informed by someone on the .NET framework group that VS 2002 uses
framework 1.0, even though I have 1.1 installed on my computer.

To take advantage of the minimum form size as well as other features of 1.1,
I need to upgrade to VS 2003.

Spose' I should have pointed out the fact that I am using 2002 somewhere in
THIS discusion.

Thanks for the help

This was a reply I recieved in the WindowsForms group:
You want it to stop all sizing (including when the mouse is dragged back to
the right to make it larger)? If so, you could send the window a
WM_CANCELMODE message; normally you do this with the SendMessage api but you
could just override the OnSizeChanged method of the form and call the
WndProc with this message.

private const int WM_CANCELMODE = 0x1F;

protected override void OnSizeChanged(S ystem.EventArgs e)
{
if (this.Width < 200 ||
this.Height < 200)
{
Message msg = new Message();
msg.HWnd = this.Handle;
msg.Msg = WM_CANCELMODE;
this.WndProc( ref msg );
}

base.OnSizeChan ged(e);
}
