_SiteConfig::MakeStringFromArray Method
For the latest version of Commerce Server 2007 Help, see the Microsoft Web site.
Note
This object is obsolete. Use SiteConfigFreeThreaded instead.
Use this method to convert an Array object into an encoded string that can be written to the Fields property.
HRESULT _SiteConfig::MakeStringFromArray(
VARIANT* varArray,
VARIANT* vtEncodedString
);
Function MakeStringFromArray(
varArray As Variant
) As Variant
Parameters
varArray
[C++][in] A pointer to the VARIANT that contains the Array to encode.
[Visual Basic]
A Variant that contains the Array to encode.
vtEncodedString
[C++][out, retval] A pointer to a VARIANT used to return the encoded string.
Return Value
[C++]
This method returns an HRESULT indicating whether it completed successfully. See the Error Values section for more details.
[Visual Basic]
If this method completes successfully, it returns Variant that contains the encoded string.
Error Values
[C++]
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, see 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.
[Visual Basic]
This method sets the Number property of the global Err object to S_OK (&H00000000) to indicate success and to standard COM error values to indicate failure. For more information about standard COM errors, see Standard COM Errors. Additional information may be available using the global Err object. In particular, the Description property may contain a text description of the error.
All ADO, SQL Server, and ODBC errors will also be returned by this method.
Remarks
The vtEncodedString parameter points to valid data only if the method completes successfully.
Note
A special group of methods is 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
Note
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 SiteConfig object resorts to storing data in an encoded string format.
Note
The MakeArrayFromString method does not implicitly convert some values in the encoded string to numeric values in the returned array as it used to do in Commerce Server 2000. Any application code that expects numeric values in the array will need to be modified to accept String values.
Example
' vEncoded is a Variant.
' vArray is a Variant.
' oSiteConfig is a SiteConfig object.
vEncoded = oSiteConfig.MakeStringFromArray(vArray)
