通过自定义属性页面更改自定义OLE_COLOR类型属性 [英] Changing a custom OLE_COLOR type property via a custom property page

问题描述

您好，我正在开发一个ActiveX控件，该控件希望能够更改其各个部分的颜色.我知道我可以使用它的股票属性页面.我不希望使用它，因为我想要更大的灵活性.
IDL文件中的声明:

Hi, I''m developing a ActiveX control that I want to able to change the colour various parts of it. I know I can use the stock property page of it. I don''t wish use it, because I want greater flexabitly.
Declartion in the IDL file:

[id(4) , helpstring("property myColour")] OLE_COLOR myColour;

我已将这种轻描淡写作为通知.因此，在控件的cpp文件中

I''ve made the implentaion as notification. Therefore, in the the control''s cpp file

DISP_PROPERTY_NOTIFY_ID(CMyActiveXCtrl, "myColour", dispidmyColour, m_myColour, OnmyColourChanged, VT_COLOR)

有问题的属性页我有一个静态控件，打算将其映射到该属性.声明为:

The property page in question I have a Static control which I intend to map to the property. Which is declared as such:

private:
    CColourStatic m_selectedColour;  // Subclassed from CStatic
    COLORREF m_nColourVal;

现在的问题是，当我取消对DDP_Text行的注释时，当我调用UpdateData时，数据交换不起作用.注释时，仅适用于静态控件.

Now the problem is when I call UpdateData the data exchange doesn''t work when I uncomment the DDP_Text line. When it commented it works for the static control only.

void CColoursPropPage::DoDataExchange(CDataExchange* pDX)
{
//  DDP_Text(pDX, IDC_BKCOLOUR_STATIC, (OLE_COLOR)m_nColourVal, _T("myColour"));
    DDX_Text(pDX, IDC_BKCOLOUR_STATIC, m_nColourVal);
    DDX_Control(pDX, IDC_BKCOLOUR_STATIC, m_selectedColour);
    DDP_PostProcessing(pDX);
}

谁能告诉我们如何解决而无需添加股票支持页面.

提前谢谢.

Alton.

Can anyone tell we how to solve without adding the stock prop page.

Thanks in advance.

推荐答案

属性getter和setter必须手工完成，其代码在此处[^

The property getter and setter has to be done by hand the code for it is here [^]
