Call this function within your control's
DoPropExchange member function to serialize or initialize a picture property of your control.
Pointer to the
CPropExchange object (typically passed as a parameter to DoPropExchange). pszPropName
The name of the property being exchanged.
Reference to a
CPictureHolder object where the property is stored (typically a member variable of your class). pictDefault
Default value for the property.
Nonzero if the exchange was successful; 0 if unsuccessful.
The property's value is read from or written to the variable referenced by
pict, as appropriate. If pictDefault is specified, it will be used as the property's default value. This value is used if, for any reason, the control's serialization process fails.
