Text File Refresh

[CarcaBot]

Hy all,
i wanna refresh a text file on each 5 seconds for example.
how i can ?

and how i can set at startup a application ?

thx in advance.

i would use a timer control for this, setting it's interval to 5000 (5 seconds) and in the form load event (or sub main if that's how the app is starting) simply start the timer

also be sure to stop the timer in the form's closing event

and how i can refresh a text file from another dialog ?
Dialog1.OpenFileDialog1.FileName.

i don't know how to refresh file reading on each x seconds...
i need it for a news ticker, i saved the file in my.settings
and i don't know how to refresh it

 

[JuggaloBrotha]

for text files there is the System.IO.StreamReader to read text files and System.IO.StreamWriter to make and append to text files

 

[CarcaBot]

yea but Refresh or reload is not a member of system.io.streamreader

// later edit

i saw you msdn forum where the topic was "auto reload file" this answer
" Unfortunately, there is no way to suppress this message in VS 2005. If you think that this would be a good addition please file a suggestion in our MSDN Product Feedback Center. (http://lab.msdn.microsoft.com/productfeedback/default.aspx) "

maybe have right !?

I dont know what you mean by refresh...

To me it could either mean you want to write completely to the file every 5 seconds replacing its content
Or you could want to look at it every 5 seconds reloading the contents

Either way, you just repeat whatever you did the first time, 5 seconds later

Please be more specific when asking your question

Or you could want to look at it every 5 seconds reloading the contents

this. i want to reload the file every x seconds.

How about you add Timer to Form, set Interval to 5000 milliseconds and Enabled to True, doubleclick it to get to the Tick event and there you write the code you want to happen each interval.

 

[CarcaBot]

Did not work .

 

[JohnH]

It does too.

 

[CarcaBot]

theoretical must work, but practical no ;-)
i dunno why don't reload the contents of file.
so.. what i can do ?

 

[JuggaloBrotha]

what's the code you're using to read the text file? (the code that's in the tick event)

 

[CarcaBot]

 Dim sr As New IO.StreamReader(My.Settings.file1)
        Dim arr() As String = Regex.Split(sr.ReadToEnd(), "\r\n")
        sr.Close()
        For Each s As String In arr
           str += " * " & s 
        Next

 

[JuggaloBrotha]

ok, I see that you're opening the file and reading all the contents of the file to an array while using a RegularExpression to do something, which is also splitting the contents of the file based on the pattern

What's the regex pattern? also what's with the {str += " * " & s} line?
