Question

当我尝试连接到Quickbooks时，我收到错误-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。可能导致这种情况的原因是什么？

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：

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将不会可用。

抱歉这个坏消息。： - /

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）？

得到错误-2147220472（无法启动Quickbooks）
