New article MQL5 Programming Basics: Files has been published:

This practice-oriented article focuses on working with files in MQL5. It offers a number of simple tasks allowing you to grasp the basics and hone your skills.

After re-naming the file, open it. It opens in Notepad editor. Write 2-3 text lines to the file and save it. Make sure that ANSI encoding is selected in the drop-down list at the bottom of the Save As window (Fig. 1).

this article is great, thank you very much for the information.

 

А как можно уменшить размер файла? Примерно имею какой то BIN файл в которой поддерживаю какие то данни, потом делаю дефрагмент файла и наконец хочу умешнит его длина, потому что сзади уже есть лишное пространство. Как етого сделать? Нужна какая та функция типа FileResize(int newSize).

 

Thanks a lot, exactly what I was looking for.

There is just a little detail in some of the code examples.

On my computer / my version of mql5, the example for "file open" does not work.

I have changed it slightly, so that it works in my case.

See here below.

However, many thanks again, this is absolutely appreciated!!!


int h = FileOpen("test1.txt", FILE_WRITE|FILE_ANSI|FILE_COMMON,"|",CP_ACP);
