得到错误-2147220472(无法启动Quickbooks)

我尝试连接到Quickbooks时收到错误-2147220472.该应用程序由Windows服务执行.日志文件如下:

这实际上有时会起作用,但我看不到模式.可能是什么导致了这个？

简而言之,用于连接的代码如下:

qbxmlConn.OpenConnection2(filename, "QBWatcher", QBXMLRP2Lib.QBXMLRPConnectionType.localQBD);
QBXMLRP2Lib.IAuthPreferences qbAuthPrefs = qbxmlConn.AuthPreferences;                                   
qbAuthPrefs.PutPersonalDataPref(QBXMLRP2Lib.QBXMLRPPersonalDataPrefType.pdpNotNeeded);
qbAuthPrefs.PutUnattendedModePref(QBXMLRP2Lib.QBXMLRPUnattendedModePrefType.umpOptional);
ticket = qbxmlConn.BeginSession(filename, QBXMLRP2Lib.QBFileMode.qbFileOpenDoNotCare);

这是这个问题的关键:

该应用程序由Windows服务执行.

由于QuickBooks的工作方式,尝试从Windows服务(例如,在后台运行的小程序而不是带有GUI的最终用户程序)连接到QuickBooks将永远无法可靠地工作.

QuickBooks使用GUI消息泵为SDK供电 - 因此,如果没有可用的GUI(例如,即使在没有用户登录到计算机的情况下运行的Windows服务中也是如此),则SDK/API将不可用.

关于这些坏消息我很遗憾.: - /

您是否可以使您的程序具有简单的GUI并且仅在用户登录时运行(如果他们需要离开计算机则锁定屏幕)？
