MDI child window Icon size

[Rainer Queck]

Hello NG,

what are the right dimensions for a window icon, used on a mdi child window?

My Problem:
I used a third party Icon-Designer to design some icons for my application.
Those icons look ok on a mdi child as long as it is not maximize.
As soon as I maximize the window, the Icon is placed into the menu bar (I
assum the is normal) but its size is aproximatly 3 times bigger.

Propably I have choosen the wrong icon size.

Thanks for hints and help on this subject.

Regards
Rainer Queck

Hi Rainer,

I performed tests on this issue, but didn't reproduce the problem on my
side.

In my test, I create an icon in the VS IDE. The size of the icon is
restricted to 32*32 and I couldn't change it. I set an MDI child form's
Icon property to this icon.

When the application is run, the MDI child form shows the icon in its title
bar. When I maximize the MDI child form, the icon is placed into the menu
bar of the MDI parent(yes, you're right that this behavior is by design)
and the icon remains the same size.

I have searched icon files on my machine and found that all icons are of
size 32*32. I found a icon of size 48*48 on the Internet and test it in my
project. The result is that the 48*48 icon remains unchanged when the MDI
child form is maximized.

So my tests show that no matter what size the MDI child form icon is, the
icon's size remains unchanged when the MDI child form is maximized.

If the problem still exists, you may send me a sample project that could
just reproduce the problem. To get my actual email address, remove 'online'
from my displayed email address.

Sincerely,
Linda Liu

Hi Linda,

I found out, that if I use differen settings for my Icon - desinger
(smaller) I don't have the problem either.
Anyhow, I prepared a little test project with the "big icon" and mailed it
to you, so that you can see the effect too.

I case my mail does not reach you, please let me know.

Regards
Rainer
