為何picture box的autoredraw=true
Rectangle好像就沒辦法正常的在picture box理正確的顯示呢
Private Sub cmdfreespace_Click()
hBrush = CreateSolidBrush(cmdfreespace.BackColor)
SetRect Rfree, 50, 50, 600, 600
FillRect picdesign.hdc, Rfree, hBrush
DeleteObject hBrush
End Sub
狀況： 只有在autoredraw=false時可以畫出來 但是會被其他視窗蓋住 缺一塊
autoredraw=true時 只有被蓋住的地方redraw
