QDataStream No transaction in progress
QDataStream is a class in Qt that provides serialization and deserialization of binary data. The error message "No transaction in progress" indicates that the application is trying to commit or rollback a transaction using QDataStream, but no transaction has been started.
Transactions in QDataStream can be started using the QDataStream::startTransaction() method. Once a transaction is started, it can be committed using the QDataStream::commitTransaction() method, or rolled back using the QDataStream::rollbackTransaction() method. If the application tries to commit or rollback a transaction without first starting one, it will result in the "No transaction in progress" error.
To resolve this error, ensure that the application is starting a transaction before committing or rolling back it using QDataStream. You can also check if there is an existing transaction in progress before attempting to commit or roll it back using the QDataStream::inTransaction() method
