PROP_DATA_ENTRY

 

Indicates the extent, or dimensions, of an ActiveX control.

Copy 

      PROP_DATA_ENTRY( 
   szDesc, 
   member, 
   vt  
)

szDesc

[in] The property description.

member

[in] The data member containing the extent; for example, m_sizeExtent.

vt

[in] Specifies the VARIANT type of the property.

This macro causes the specified data member to be persisted.

When you create an ActiveX control, the wizard inserts this macro after the property map macro BEGIN_PROP_MAP and before the property map macro END_PROP_MAP.

Example

In the following example, the extent of the object (m_sizeExtent) is being persisted.

C++
Copy 
BEGIN_PROP_MAP(CMyWindow)
   PROP_DATA_ENTRY("_cx", m_sizeExtent.cx, VT_UI4)
   PROP_DATA_ENTRY("_cy", m_sizeExtent.cy, VT_UI4)
END_PROP_MAP()
C++
Copy 
BEGIN_PROP_MAP(CMyCompositeCtrl)
   PROP_DATA_ENTRY("Width", m_nWidth, VT_UI4)
   PROP_DATA_ENTRY("Height", m_nHeight, VT_UI4)
END_PROP_MAP()
