@error & End Of File

[frank10]

I made a function to read each line of a file and when I reach EOF, it should exit the func, BUT @error never goes to -1, it stays always equal to 0. Why?

dim $_file = FileOpen("H:\Temp\testFireLinks.txt", 0)

If $_file = -1 Then
    MsgBox(0, "Error", "Unable to open file.")
    return;Exit
EndIf


; Read in lines of text until the EOF is reached
While 1
    
    dim $_line = FileReadLine($_file)
        
       ;I put the line read to the clipboard, to use later
    ClipPut( $_line ) 
        
    If @error = -1 Then 
        ExitLoop
    EndIf
     
       ;other simple code, then paste the line, with CTRL-V:
    Send('^v')

Wend

FileClose($_file)

Any ideas?

move the error check

dim $_line = FileReadLine($_file)

If @error = -1 Then ExitLoop

8)

move the error check

dim $_line = FileReadLine($_file)

If @error = -1 Then ExitLoop

8)

The above code is correct - the reason is because @error is reset to 0 every time a function is called. In the original code, ClipPut is being tested for @error status, not the FileReadLine.

Oh thank you, now it's clear.

So if I made this (I originally thought it to shrink the code) :

ClipPut( FileReadLine($_file) )

I guess I cannot check the @error of File.

So the only way to go is as you told me before, is it true?

Correct, if you have one function inside another, you cannot check the @error of the internal function.
