I have a application that I am updating for work, and I have two processes, one is a csv writer and another a rest API call I want to record the time it takes for the processes to run then display each individual elapsed time in a rich text box I am using for an event log. (we cant have an actual event log because pretty much all users don't have admin privileges). I also want to add further information including from message boxes if possible if not Ill just add additional messaging. This is an application that I inherited and the original author has sense retired.

    Thanks for reaching out!

    You can use Stopwatch in C# to measure how long each process takes, then append the elapsed time into a Rich Textbox that acts as your event log. Stopwatch gives accurate timing for any operation, such as your CSV writer and REST API call.

    After each process finishes, you simply write the elapsed time into your RichTextBox, which you are already using as an event log. This works for users without admin access, since it does not require the Windows Event Log.

    You can also log additional details like results from MessageBox prompts or any custom status messages by appending text into the same RichTextBox

     The overall flow is:

    1.Start a Stopwatch

    2.Run the process (CSV write/ API call)

    3.Stop the Stopwatch

    4.Append a log entry into the RichTextBox with the time taken.

    5.Add any custom message you want.

    This keeps all your timing information and messages in one place and avoids the need for elevated permissions.
