Question

vb中怎么一点击按钮可以把Image中的图片清空

Answer 1

磁盘
SavePicture Picture1.Image, App.Path & "\1.bmp"
清空用LoadPicture,如果Set Nothing就干掉了对象
Picture1.Picture = LoadPicture()

---------------------------------
汗 你说上面有控件?
那你最好用API了 BitBlt 想怎么搞都行
你想清空上面的控件 就只能将那些控件的Visible 设为False了

Answer 2

Private Sub Command1_Click()
Set Image1.Picture = Nothing
End Sub

Answer 3

Private Sub Command1_Click()
Image1.Picture = loadpicture("")
End Sub
