GetSignatureAndWriteValue 方法示例

下列示例创建ESignature对象，检查节点是否启用了电子签名，确定标签FIX32.thisnode.D01.F_CV是否需要电子签名，捕获签名，写入新值，并向审计跟踪发送一条消息。

Dim ESig As Object

Dim bNodeSignEnabled As Boolean

Dim bSigRequired As Boolean

Dim NewValue As Variant

'创建 ESignature 对象

Set ESig = CreateObject("ElectronicSignature.ESignatureFactory")

'检查节点是否启用了电子签名

ESig.IsNodeSignEnabled bNodeSignEnabled

If bNodeSignEnabled = True Then

'检查标签是否要求电子签名

ESig.Initialize "Fix32.thisnode.DO1.F_CV"

ESig.IsSignatureRequired 0, bSigRequired

If bSigRequired = True Then

'捕获签名，写入新值并向审计跟踪发送一条消息

NewValue = 1

ESig.GetSignatureAndWriteValue 0, NewValue

Else

MsgBox "Signature is not required for this tag."

End If

Else

MsgBox "Signature is not enabled on this node."

End If
