MsiRecordSetStringW function (msiquery.h)
The MsiRecordSetString function copies a string into the designated field.
Syntax
UINT MsiRecordSetStringW(
[in] MSIHANDLE hRecord,
[in] UINT iField,
[in] LPCWSTR szValue
);
Parameters
[in] hRecord
Handle to the record.
[in] iField
Specifies the field of the record to set.
[in] szValue
Specifies the string value of the field.
Return value
This function returns UINT.
Remarks
In the MsiRecordSetString function, a null string pointer and an empty string both set the field to null. Attempting to store a value in a nonexistent field causes an error.
To set a record string field to null, set szValue to either a null string or an empty string.
Note
The msiquery.h header defines MsiRecordSetString as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
