c# - Find First check number in Quickbooks using QBFC

Question

I am using Quickbooks QBFC and want to retrive the value of "First Check Number" field programatically.

It can be found in Quickbooks at File>Print Forms>Checks

Please suggest how this can be done or any reference i can look at.

您不能直接执行此操作，但您可以查询最近针对您感兴趣的帐户开出的支票。默认的第一张支票号码将比已开出的最高支票号码大一个。

作为一项规则，我不会为人们编写代码，我今天例外，只是因为今天是星期五，我的心情很疯狂。以下代码可用作有用的最后一个校验号例程的起点。为了有一个现实的、可用的例程，你，而不是我，将不得不处理与人们使用支票簿的方式相关的所有怪癖：非数字数字、乱序数字等。

请注意：此代码使用Zombie 开源库和 QBFC 11。

class CheckNumbers
{
    private const int DATE_INTERVAL = -7;

    private string _accountName;
    private DateTime _lastToDate;
    private DateTime _lastFromDate;

    public CheckNumbers(string accountName)
    {
        _accountName = accountName;
        _lastToDate = DateTime.Today;
        _lastFromDate = _lastToDate.AddDays(DATE_INTERVAL);
    }

    private void SetCriteria(IORTxnQuery qry)
    {
        qry.TxnFilter.AccountFilter.ORAccountFilter.FullNameList.Add(_accountName);

        var dateFilter = qry.TxnFilter.ORDateRangeFilter.ModifiedDateRangeFilter;

        dateFilter.FromModifiedDate.SetValue(_lastFromDate, true);
        dateFilter.ToModifiedDate.SetValue(_lastToDate, true);
    }

    private void ProcessCheckNumber(string checkNumber, ref int highestNumber)
    {
        if (!string.IsNullOrEmpty(checkNumber))
        {
            int thisCheck;
            if (!int.TryParse(checkNumber, out thisCheck))
            {
                throw new Exception(string.Format("Check number {0} cannot be read as an integer", checkNumber));
            }
            if (thisCheck > highestNumber) highestNumber = thisCheck;
        }
    }

    public int GetLastCheckNumber()
    {
        DateTime failSafe = DateTime.Parse("1/1/2010");

        using (var cn = Zombie.ConnectionMgr.GetConnection())
        {
            int highestCheck = 0;

            while (highestCheck == 0 && _lastFromDate > failSafe)
            {
                var batch = cn.NewBatch();

                var checkQuery = batch.MsgSet.AppendCheckQueryRq();
                checkQuery.IncludeRetElementList.Add("RefNumber");

                SetCriteria(checkQuery.ORTxnQuery);

                batch.SetClosures(checkQuery, b =>
                    {
                        var checks = new Zombie.QBFCIterator<ICheckRetList, ICheckRet>(b);
                        foreach (var check in checks)
                        {
                            ProcessCheckNumber(Zombie.Safe.Value(check.RefNumber), ref highestCheck);
                        }
                    });

                var billCheckQuery = batch.MsgSet.AppendBillPaymentCheckQueryRq();
                billCheckQuery.IncludeRetElementList.Add("RefNumber");

                SetCriteria(billCheckQuery.ORTxnQuery);

                batch.SetClosures(billCheckQuery, b =>
                    {
                        var checks = new Zombie.QBFCIterator<IBillPaymentCheckRetList, IBillPaymentCheckRet>(b);
                        foreach (var check in checks)
                        {
                            ProcessCheckNumber(Zombie.Safe.Value(check.RefNumber), ref highestCheck);
                        }
                    });

                if (!batch.Run()) return 0;

                _lastToDate = _lastFromDate;
                _lastFromDate = _lastToDate.AddDays(DATE_INTERVAL);
            }

            return highestCheck;
        }
    }
}
