Question

我正在尝试编写一个VB.net WPF程序，它将向客户添加自定义注释。 Intuit让我围绕他们的代码示例，不会从C＃转换为VB.net。

有人可以向我展示一个非常简单的示例，仅显示添加客户名称吗？省略任何错误检查等，我可以搞清楚。我只是不知道如何编写与quickbooks的连接并发送请求。也许是一个带有文本框和按钮的简单表单，其功能是将名称放在文本框中，然后单击按钮添加客户名称。

我一直对来自Intuit for Quickbooks SDK的糟糕代码示例感到厌恶。话虽如此，我仍然使用它们;修复代码后，它们非常有用。

您还需要添加对Intuit Quickbooks SDK QBFC7Lib的引用;根据版本的不同，它可能会略有不同。

以下是使代码有用所需的操作（使用编辑＆gt;快速替换）：

将//替换为'（评论）
删除所有;（分号）
将==替换为=
将For j = 0替换为For j as Integer = 0
将responseList.GetAt(i)替换为responseList.GetAt(j)
删除尾随.（点）
将Integerfor替换为Integer（下一行）for
将DataExtRet替换为DataExtRet.（仅当它显示错误时）
检查是否存在任何其他错误
删除不需要的内容

当您第一次运行它时，您需要打开Quickbooks并准备好从Quickbooks授予权限。这是一个修复错误的示例。

    End Sub

    Private Sub WalkCustomerAddRs(ByVal responseMsgSet As IMsgSetResponse)
        If (responseMsgSet Is Nothing) Then
            Exit Sub
        End If

        Dim responseList As IResponseList
        responseList = responseMsgSet.ResponseList
        If (responseList Is Nothing) Then
            Exit Sub
        End If

        'if we sent only one request, there is only one response, we'll walk the list for this sample
        For j As Integer = 0 To responseList.Count - 1
            Dim response As IResponse
            response = responseList.GetAt(j)
            'check the status code of the response, 0=ok, >0 is warning
            If (response.StatusCode >= 0) Then
                'the request-specific response is in the details, make sure we have some
                If (Not response.Detail Is Nothing) Then
                    'make sure the response is the type we're expecting
                    Dim responseType As ENResponseType
                    responseType = CType(response.Type.GetValue(), ENResponseType)
                    If (responseType = ENResponseType.rtCustomerAddRs) Then
                        ''upcast to more specific type here, this is safe because we checked with response.Type check above
                        Dim CustomerRet As ICustomerRet
                        CustomerRet = CType(response.Detail, ICustomerRet)
                        WalkCustomerRet(CustomerRet)
                    End If
                End If
            End If
        Next j
    End Sub

    Private Sub WalkCustomerRet(ByVal CustomerRet As ICustomerRet)
        If (CustomerRet Is Nothing) Then
            Exit Sub
        End If

        'Go through all the elements of ICustomerRet
        'Get value of ListID
        Dim ListID1 As String
        ListID1 = CustomerRet.ListID.GetValue()
        'Get value of Name
        Dim Name5 As String
        Name5 = CustomerRet.Name.GetValue()

    End Sub

End Class

End Module

我经常看到的另一个问题是代码从“retlist”跳到“ret”。这通常发生在例如查询中ReceivePaymentQuery。这不是DoCustomerAdd的问题。在转换其他方法时，我只在此提及它以供参考。

来自OSR的代码：

Public Sub WalkReceivePaymentRet(ByVal ReceivePaymentRet As IReceivePaymentRetList)
    If (ReceivePaymentRet Is Nothing) Then
        Exit Sub
    End If

修复如下：

Public Sub WalkReceivePaymentRet(ByVal ReceivePaymentRetList As IReceivePaymentRetList)

    For a As Integer = 0 To ReceivePaymentRetList.Count - 1
        Dim ReceivePaymentRet As IReceivePaymentRet

        ReceivePaymentRet = ReceivePaymentRetList.GetAt(a)

        If (ReceivePaymentRet Is Nothing) Then
            Exit Sub
        End If

通过执行以下操作，确保将“ AddCu”添加到Quickbook中：

QB->编辑->首选项->集成应用程序->公司首选项

允许访问：✓|应用名称：AddCu

导入Interop.QBFC13

Public Sub AddCu()
    ' Create a QBSessionManager object:
    Dim SessionManager As QBSessionManager
    SessionManager = New QBSessionManager

    ' Create an IMsgSetRequest object (the parameters specify US QuickBooks and the 6.0 spec):
    Dim CustomerSet As IMsgSetRequest
    CustomerSet = SessionManager.CreateMsgSetRequest("US", 6, 0)

    ' Create an ICustomerAdd object:
    Dim customer As ICustomerAdd

    customer = CustomerSet.AppendCustomerAddRq

    ' Set the ICustomerAdd object's field values:
    customer.Name.SetValue("Joey Hamham")

    customer.Phone.SetValue("315-253-2642")

    customer.Email.SetValue("bla@gmail")

    ' The request message set for this example is complete
    ' Open a connection:
    SessionManager.OpenConnection("App", "AddCu")
    ' Begin a session:
    SessionManager.BeginSession("", ENOpenMode.omDontCare)

    ' Create a IMsgSetResponse object:
    Dim Resp As IMsgSetResponse

    ' Call DoRequests, passing the IMsgSetRequest object that was populated with a 
    Resp = SessionManager.DoRequests(CustomerSet)

    ' Display the unprocessed QBXML in the response in a message box:
    MsgBox(Resp.ToXMLString)

    ' End the session:
    SessionManager.EndSession()
    ' Close the connection:
    SessionManager.CloseConnection()
    ' Clear the QBSessionManager
    SessionManager = Nothing
End Sub
