@pcinfogmach כתב בשאלה בwpf האם יש דרך להסיר את הצל שסביב האובייקט window:
אבל מסתבר שאם עושים את זה אז מאבדים את היכולת לשנות את הגודל של החלון.
עריכה: צריך לעשות כך במקום
<WindowChrome.WindowChrome>
<WindowChrome GlassFrameThickness="0"
CornerRadius="0"
CaptionHeight="0"/>
</WindowChrome.WindowChrome>
מצו"ב על הדרך קוד לuserform עם אפשרות דומה לחלון של הגדלה וגרירה (לא מושלם אבל עובד)

היה מעניין אבל מרגיש לי קצת בזבוז זמן. שוין.
