Parameters

varSrc

An existing COleVariant or VARIANT object to be copied into the new COleVariant object.

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.

dateSrc

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.

Remarks

All of 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( dateSrc )   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.
