Summary:

When writing data such as events / customized messages to a Device in logging mode (DevOpen mode 8), the entries are getting overwritten instead of appending to the last one.


Solution:

This happens because the DevClose() function by default is set to mode 0 which is to remove logging.

use:

DevClose(hDev,1) - which keeps the logging enabled and the entries should get appended.
