FileWriteLine() ?

HI,

I think you can treat it like a txt file. Does that help?

HI,

$file = FileOpen("test.dat", 1)

; Check if file opened for writing OK
If $file = -1 Then
    MsgBox(0, "Error", "Unable to open file.")
    Exit
EndIf

FileWrite($file, "Line1")
FileWrite($file, "Still Line1" & @CRLF)
FileWrite($file, "Line2")

FileClose($file)

$file = FileOpen("test.dat", 0)

; Check if file opened for reading OK
If $file = -1 Then
    MsgBox(0, "Error", "Unable to open file.")
    Exit
EndIf

; Read in 1 character at a time until the EOF is reached
$outPut = FileRead($file)

MsgBox(0, "Char read:", $outPut)
FileClose($file)

Open with ultraedit works fine.

Hi,

1. How did you "read"?

2. what did you get back?

3. What do you want to write?

4. ? where?; ? append to end?

best, Randall

1. With FileReadLine

2. The Characters...not in Hex

3. Well i just want to change some values but not all of them...

Did you already check with an HEX editor if the file contain UNICODE characters ?

Hi,

1. How did you "read"?

With FileReadLine

probably needs a binary read of some sort to get a line properly; are there lines anyway? - probably worked coincidentally when it found a "null" perhaps?

2. what did you get back?

The Characters

Not a good answer!

3. What do you want to write?

Well i just want to change some values

Starts to sound a little edgy! ; What characters Exactly did you want to replace, with what characters Exactly, where exactly, and Why exactly?

Could u explain that a bit more?

When i used FileReadLine I got back A(F etc. which is actually not, what i want...

This is a setting file which I need to change through an interface, as otherwise it would be quite annoying.

The values go from 0 to 100 an I need to change some of them. I could do it through a hex editor, but thats not what I want.

I want, for example, change the first value but keep the rest of the values, or change the 5th value, but keep the rest...

Is that a bit clearer now?
