Hello,

I have a problem with the script above.

FileRead doesn't read the file content, but returns no errors.

Can someone help me, please?

Thank you

Bye

ofc it doesn't read the file content

FileOpen($IniAppSearchedQueriesPath, 1)

is for writing

FileOpen($IniAppSearchedQueriesPath, 0)

is for reading

change that line and c if it works

O_O If I use 0, it works!!!

I want to use 1 because I need both to read and write the file. How can I do this?

if your not working with alot of data

when you read it in mode 0, change or add data while data is still in variable.

after that open with FileOpen on mode

2 = Write mode (erase previous contents)

and write it all in one shot

dont forgot to use

FileClose($file)

every time you try to reopen file in diffrent mod

But why should I open the same file twice???

In my opinion, this is a bug. If I open the file for writing (1), it should be opened also for reading (0) because 1 + 0 = 1

For write and read file from same handler u can use FileSetPos

But why should I open the same file twice???

Safer, Simpler,,, atleast for me :) Edited by rvn

if you only want to open the file once then you need to use filesetpos() to set the position of of the next read or write. Opening a file with option 1 sets the position at the end of the file so when you read the files it tries to read the data beyond the end of the file and of course there is no data to read in that position. If you set the file position to the start of the file and then read it you will get the contents as you expected. The the position is specified in Bytes/Chars.

Example:

$IniAppSearchedQueriesPath = @ScriptDir&"searched_queries.txt"
$SearchedQueriesFileOpen = FileOpen($IniAppSearchedQueriesPath, 1)
FileSetPos($SearchedQueriesFileOpen,1,0)
$SearchedQueriesFileRead = FileRead($SearchedQueriesFileOpen)
MsgBox(0,'',$SearchedQueriesFileRead&@CRLF&@extended&@CRLF&@error)

Bowmore thank you for your reply. However I think I will open the file twice because it's a simpler solution.
