Dear code project members,
I'm a very beginer in Visual C# and I would like you to help me with this problem, which is too simple for a high level community like you but very difficult for me.

The problem:
I have a text file which contains 14 columns and more than 3500 rows of integers. I need to read that file by the click of a button and then load the whole contents into a multi dimensional array. From this array 14 textboxes will be loaded. Then I need that content to change every 50ms. I'll use this application to create a socket over which I'll send the data to a robot controlling a its trajectory.

Best regards

Solution 1

If you need info about creating, handling arrays: Array tutorial[^]
If you need info about general file reading stuff like ReadAllText ReadAllLines etc:System.IO.File[^]
If you arent happy with just File class: System.IO.TextReader[^]
If you want a general purpose timer:System.Timers.Timer[^]
There are alternatives to timer class like using threads and use thread.sleep to manage timing checkout System.Threading.Thread[^] also there are many articles and Q&A in CodeProject as well. For instance How to pass ref parameter to the thread[^].
Good luck.
