Hi VAer-4038,
>>Does the "menustrip" in your description refer to the title bar of the child window?
If not, please explain in detail.
And have you set your parent form's WindowState property to Maximized?
Due to parent form is a container for multiple-document interface (MDI) child forms, so there will be some problems when the child window is larger than the parent window.
I made a test with your information and setted parent form's WindowState property to Maximized.
Here are test result:
Child form Maximized:
Child form Minimized:
>> this system icon is on the menustrip, not on the parent form. This icon is not child form icon.
Which icon you are referring to, and you can change the icon of the child window to determine whether it is its icon.
When I set FormBorderStyle to none or sizeable, the child form all appears on "menustrip".
>>when I minimize child form, form icon disappears from menustrip; at this moment menustrip has buttons only.
Does your "button" refer to icon or others?
Best Regards,
Daniel Zhang
