_GlobalConfig2::MakeStringFromSimpleList Method
For the latest version of Commerce Server 2007 Help, see the Microsoft Web site.
Use this method to convert a SimpleList object into an encoded string, which can be written to the Fields property.
HRESULT _GlobalConfig2::MakeStringFromSimpleList(
IDispatch** slist,
BSTR* strEncodedString
);
Function MakeStringFromSimpleList(
slist As Object
) As String
Parameters
slist
[C++][in] An IDispatch interface pointer to the SimpleList object that you want to convert into an encoded string.
[Visual Basic]
An object reference to the SimpleList object that you want to convert into an encoded string.
strEncodedString
[C++][out, retval] A pointer to a String 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]
None.
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 Initialize method must be called before this method can be called.
The strEncodedString parameter contains valid data only if the method completes successfully.
Note
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
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, SimpleLists, or objects as Fields columns. Therefore, the GlobalConfig2 object resorts to storing data in an encoded string format.
Example
' vEncoded is a string.
' vArray is a Variant.
' varMySimpleList is an object reference to a SimpleList object.
' oGlobalConfig2 is a GlobalConfig2 object.
vEncoded = oGlobalConfig2.MakeStringFromSimpleList(varMySimpleList)
