I have added the File Menu (from File Menu Template) to my Main Menu along with Open Dialog and Save Dialog and it is not working. I have compared it with working code and it is the same. The difference is under Structure, the File Icons are partially shown which seems to indicate something amiss. Thanks, Jeff

How do I save binary data to a file with a fixed header? Like using APPEND for text.

Got it: Tools-->Manage Platforms-->Additional Options-->Teechart Standard

Is there no TChart component in 10.4 Community Edition??

Thanks all, enough said... XP is replaced.

I am using the FTDI chip, FT4232.

No, I'm not doing any Bluetooth. But, I am using the Winsoft version ComPort. How do I find out if that's calling it?

Yes, XP must go away!

I am using TComPort

I don't have that answer. I am using Delphi to create an App to log data through USB. I am not an experienced programmer.

The error is: The procedure entry point SetupDiGetDevicePropertyW could not be located in the dynamic link library SetupAPI.dll

It looks like XP doesn't support SetupDiGetDevicePropertyW. Any thoughts?

I have created an App with Delphi 10.4 and Windows 10. Will I be able to run the App on Windows XP??

All sensors are working and I'm logging data! I would like to display live data trends and see TChart should do that, but I can't find it. Is it not available in the Community Edition 10.4?

Thanks again. That code works in converting to a string, although I am getting what seem to be random memory errors.
