Writing to SD Card

[ahmedkhalid]

Hello Everyone!!
Sorry I am here to disturb you guys again . I want to know how I can move to next line of a text editor file using SD/FAT functions?

Hello,

You would do something like this.

Initialise
OpenFile("file.txt")
LineString = ReadStringFromFile(MaxLength, '\n')

The ReadStringFromFile function will then populate the LineString variable with a line of data read from the file terminating at a new line character.

Well Thanks for the response! But in my case I have to write into the text file and after writing few bytes I have to move to the next line. How I can do that?

To move to the next line for a Windows editor write the string "\r\n" (or the characters '\r' and '\n') at the end of your line.

Plus one more thing, how can I create a file and write on it simultaneously? Like I created a file and after opening it tried to write something but when the program was executed, during its first execution only a file was created and nothing get written, but when the program was executed again then I was able to write onto the file. So How can I do both the tasks in a single execution cycle? I hope you get my question!
