Dim objMetaData As AttributeMetaData

strModelName = "CCSDemo"
strServerName = "localhost"
strEntity = "AcctTransactions"
strAttribute = "AcctNumber"

Set Verastream_Session = New AppConnModel
Verastream_Session.ConnectToModel strServerName, strModelName
Set objMetaData = Verastream_Session.GetAttributeMetaData(strEntity, strAttribute)

MsgBox ("Length " & objMetaData.Length)

Verastream_Session.Disconnect
Set Verastream_Session = Nothing
Set objMetaData = Nothing

MetaDataType Property

Used to get the metadata type of an attribute.

Syntax

object.MetaDataType

Part	Description
object	An AttributeMetaData object

Remarks

Use the MetaDataType property to get the type of metadata within a Verastream table. The enumeration values for AppConnMetaDataType are defined in the Type Library.

Example

Dim Verastream_Session As AppConnModel
Dim strModelName, strServerName, strEntity, strAttribute As String
Dim objMetaData As AttributeMetaData

strModelName = "CCSDemo"
strServerName = "localhost"
strEntity = "AcctTransactions"
strAttribute = "AcctNumber"

Set Verastream_Session = New AppConnModel
Verastream_Session.ConnectToModel strServerName, strModelName
Set objMetaData = Verastream_Session.GetAttributeMetaData(strEntity, strAttribute)

MsgBox ("MetaDataType " & objMetaData.MetaDataType)

Name Property

Used to get the name of an attribute.

Syntax

object.Name

Part	Description
object	An AttributeMetaData object

Remarks

Use the Name property to get the name of an attribute.

Example

Remarks

Use the ReadVariable property to get the read variable of an attribute. The ReadVariable is the model variable that gets updated when executing a ReadFromMappedAttr command in an operation.

Example

Dim Verastream_Session As AppConnModel
Dim strModelName, strServerName, strEntity, strAttribute As String
Dim objMetaData As AttributeMetaData

strModelName = "CCSDemo"

strServerName = "localhost"
strEntity = "AcctTransactions"
strAttribute = "AcctNumber"

Set Verastream_Session = New AppConnModel
Verastream_Session.ConnectToModel strServerName, strModelName
Set objMetaData = Verastream_Session.GetAttributeMetaData(strEntity, strAttribute)

MsgBox ("TerminalAttributesEnabled " & objMetaData.TerminalAttributesEnabled)

Verastream_Session.Disconnect
Set Verastream_Session = Nothing
Set objMetaData = Nothing

WriteVariable Property

Used to the write variable of an attribute.

Syntax

object.WriteVariable

Part	Description
object	An AttributeMetaData object

Remarks

Use the WriteVariable property to get the write variable of an attribute. The WriteVariable is the model variable that a value is gotten from when the WriteToMappedAttrf command is called within an operation.

Example

Dim Verastream_Session As AppConnModel
Dim strModelName, strServerName, strEntity, strAttribute As String
Dim objMetaData As AttributeMetaData

strModelName = "CCSDemo"
strServerName = "localhost"
strEntity = "AcctTransactions"
strAttribute = "AcctNumber"

Set Verastream_Session = New AppConnModel
Verastream_Session.ConnectToModel strServerName, strModelName
Set objMetaData = Verastream_Session.GetAttributeMetaData(strEntity, strAttribute)

MsgBox ("WriteVariable " & objMetaData.WriteVariable)

Verastream_Session.Disconnect
Set Verastream_Session = Nothing
Set objMetaData = Nothing
