IDataFunctions::ConvertNumberString

The ConvertNumberString method converts a string representation of a number to a long VARIANT, based on the specified locale.

Syntax

HRESULT ConvertNumberString(
VARIANT vtNum,// in
VARIANT vtLocale,// in
VARIANT *pvarNumber// out
);

Parameters

vtNum

A VARIANT that contains the string representation of the number to convert. The vt member of this VARIANT must be initialized to VT_BSTR, and its pbstrVal member must contain the BSTR value to convert.

vtLocale

A VARIANT that specifies the locale on which to base the conversion. If this VARIANT is empty (VT_EMPTY) or NULL (VT_NULL), ConvertNumberString uses the locale specified by a previous call to put_Locale.

pvarNumber

If successful, a pointer to a VARIANT that contains the converted value. ConvertNumberString initializes this VARIANT’s vt member to VT_I4, and stores the converted value in its lVal member. If unsuccessful, ConvertNumberString sets the Vt member to VT_NULL.
