When trying to connect to QuickBooks using VB Demo, I am facing the error :
QB Begin Session Failed. Error Calling OpenQBConnection Returned Error: 10061 -  Connection refused
Please first keep QuickBooks running and logged in as Admin in single user mode. Go to QuickBooks, "File" list menu, and then check that if there is "switch to Multi-User Mode" option. If there is, then you are running QuickBooks in single user mode. But if there is no this option, click "switch to single user mode" option in the same list menu to set QuickBooks running at single user mode.
If you are not sure how to connect to QuickBooks using QODBC, please refer to this article for more information:
If you are using "Remote Connector" to build a remote connection, please check that if you have configured it correctly.
Please refer to this article for more information about setup "Remote Connector":
Please make sure you have unchecked "Connect To QuickBooks Online Edition" option in QODBC Setup Screen, "Online Edition" window if you are not going to use QODBC to access Connect To QuickBooks Online Edition(QBOE):
And also please make sure you have unchecked "Use RDS Client/Server" option in QODBC Setup Screen, "RDS Server" window if you are not going to access QuickBooks remotely:
RDS is a product from QuickBooks, we may not be able to provide much help if there is any problem when using RDS. If you are going to setup QODBC to access QuickBooks remotely, Please use QRemote. About more information of using QRemote as a remote access solution, please refer to this article:
