Use this method to convert an Array object into an encoded string, which can be written to the Fields property.

Definition

HRESULT _GlobalConfig::MakeStringFromArray(VARIANT*varArray,VARIANT*vtEncodedString);

Parameters

varArray

[in] A pointer to the VARIANT that contains the Array to encode.

vtEncodedString

[out, retval] A pointer to a VARIANT used to return the encoded string.

Return Values

This method returns an HRESULT indicating whether or not it completed successfully. See the Error Values section for more details.

Error Values

This method returns S_OK (0x00000000) to indicate success and standard COM HRESULT error values to indicate failure. For more information about standard COM errors, seeĀ Standard COM Errors. Additional information may be available using the global Err object, which can be accessed using the API function GetErrorInfo. In particular, the GetDescription method of the IErrorInfo interface may return a text description of the error.

All ADO, SQL, and ODBC errors will also be returned by this method.

Remarks

The Initialize method must be called before this method can be called.

The vtEncodedString parameter contains valid data only if the method completes successfully.

  • There is a special group of methods used with multivalued arrays. These methods are the only approved and recommended way of storing and retrieving multivalued arrays in the Administration database. You must use the following methods with any property that has the structure of a multivalued array:
    • MakeArrayFromSimpleList

    • MakeSimpleListFromArray

    • MakeArrayFromString

    • MakeStringFromArray

  • This method can only be used when updating values exposed by the Fields object. The client-side disconnected ADO recordset has no support for Variants, Arrays, or objects as Fields columns. Therefore, the GlobalConfig object resorts to storing data in an encoded string format.
