Program doesn't write to files

[Wicked_Caty]

I've written a short program that calculates all values of a mathematical function in a user-defined interval. The data is written to an user-defined file during that process. Unfortunately, there is no file. I don't have a clue what's wrong with my program, and I've been trying to solve that for nearly 2 hours now. Obviously without success.

The calculation is done properly (added a ConsoleWrite() to check that), so it must be the FileWrite() that doesn't work.

Thanks for the help!

You need to add some error checking to your script.
Is FileOpen successful? Is FileWrite successful?
The help file shows you how to check for errors.

How do I do error checking exactly?

I don't know if that is successful. The only things I know are that the file isn't created :/

The help file explains what is returned by a function in case of an error. Example:

$f = FileOpen(...)
$If $F = -1 Then ... ; An error has occurred

$fw = FileWrite(...)
If $fw = 0 Then .. ; An error has occurred

FileOpen() and FileWrite() don't work. 

 

Edit: I guess FileWrite() doesn't work, because FileOpen() doesn't work in the first place

The default mode for FileOpen is $FO_READ.
To write to a file you need to set the mode:

#include <FileConstants.au3>
$f = FileOpen("Your filename goes here", $FO_APPEND) ; Or $FO_OVERWRITE if you always want to overwrite an existing file

Thanks! It works now
