用户控件窗口下用了两个图片控件Picture1和Picture2
例图1:
自定义成员属性A1和A2,A1=Picture1.Picture A2=Picture2.Picture
代码:
'注意!不要删除或修改下列被注释的行!
'MappingInfo=Picture1,Picture1,-1,Picture
Public Property Get a1() As Picture
Set a1 = Picture1.Picture
End PropertyPublic Property Set a1(ByVal New_a1 As Picture)
Set Picture1.Picture = New_a1
PropertyChanged "a1"
End Property'注意!不要删除或修改下列被注释的行!
'MappingInfo=Picture2,Picture2,-1,Picture
Public Property Get a2() As Picture
Set a2 = Picture2.Picture
End PropertyPublic Property Set a2(ByVal New_a2 As Picture)
Set Picture2.Picture = New_a2
PropertyChanged "a2"
End Property'从存贮器中加载属性值
Private Sub UserControl_ReadProperties(PropBag As PropertyBag) Set Picture = PropBag.ReadProperty("a1", Nothing)
Set Picture = PropBag.ReadProperty("a2", Nothing)
End Sub'将属性值写到存储器
Private Sub UserControl_WriteProperties(PropBag As PropertyBag) Call PropBag.WriteProperty("a1", Picture, Nothing)
Call PropBag.WriteProperty("a2", Picture, Nothing)
End Sub生成ocX后在EXE工程里面调用 将A1绑定一张图 再将A2绑定一张图片, 在没有点击运行的时候显示正常,点击运行程序后图片就没有了自动清空了,这个什么原因啊?
图2:控件
'从存贮器中加载属性值
Private Sub UserControl_ReadProperties(PropBag As PropertyBag) Set Picture1.Picture = PropBag.ReadProperty("a1", Nothing)
Set Picture2.Picture = PropBag.ReadProperty("a2", Nothing)
End Sub'将属性值写到存储器
Private Sub UserControl_WriteProperties(PropBag As PropertyBag) Call PropBag.WriteProperty("a1", Picture1.Picture, Nothing)
Call PropBag.WriteProperty("a2", Picture2.Picture, Nothing)
End Sub
