• pSrc
  A pointer to a VARIANT object that will be copied into the new COleVariant object.

• lpszSrc
  A null-terminated string to be copied into the new COleVariant object.

• vtSrc
  The VARTYPE for the new COleVariant object.

• strSrc
  A CString object to be copied into the new COleVariant object.

• nSrc, lSrc
  A numerical value to be copied into the new COleVariant object.

• vtSrc
  The VARTYPE for the new COleVariant object.

• curSrc
  A COleCurrency object to be copied into the new COleVariant object.

• fltSrc, dblSrc
  A numerical value to be copied into the new COleVariant object.

• timeSrc
  A COleDateTime object to be copied into the new COleVariant object.

• arrSrc
  A CByteArray object to be copied into the new COleVariant object.

• lbSrc
  A CLongBinary object to be copied into the new COleVariant object.

• pidl
  A pointer to a ITEMIDLIST structure to be copied into the new COleVariant object.

Remarks

All these constructors create new COleVariant objects initialized to the specified value. A brief description of each of these constructors follows.

• COleVariant( )   Creates an empty COleVariant object, VT_EMPTY.

• COleVariant( varSrc )   Copies an existing VARIANT or COleVariant object. The variant type is retained.

• COleVariant( pSrc )   Copies an existing VARIANT or COleVariant object. The variant type is retained.

• COleVariant( lpszSrc )   Copies a string into the new object, VT_BSTR (UNICODE).

• COleVariant( lpszSrc**,** vtSrc )   Copies a string into the new object. The parameter vtSrc must be VT_BSTR (UNICODE) or VT_BSTRT (ANSI).

• COleVariant( strSrc )   Copies a string into the new object, VT_BSTR (UNICODE).

• COleVariant( nSrc )   Copies an 8-bit integer into the new object, VT_UI1.

• COleVariant( nSrc**,** vtSrc )   Copies a 16-bit integer (or Boolean value) into the new object. The parameter vtSrc must be VT_I2 or VT_BOOL.

• COleVariant( lSrc**,** vtSrc )   Copies a 32-bit integer (or SCODE value) into the new object. The parameter vtSrc must be VT_I4, VT_ERROR, or VT_BOOL.

• COleVariant( curSrc )   Copies a COleCurrency value into the new object, VT_CY.

• COleVariant( fltSrc )   Copies a 32-bit floating-point value into the new object, VT_R4.

• COleVariant( dblSrc )   Copies a 64-bit floating-point value into the new object, VT_R8.

• COleVariant( timeSrc )   Copies a COleDateTime value into the new object, VT_DATE.

• COleVariant( arrSrc )   Copies a CByteArray object into the new object, VT_EMPTY.

• COleVariant( lbSrc )   Copies a CLongBinary object into the new object, VT_EMPTY.
