Jun 9, 2009I'm working on a project with a large multidimensional array
resrv(200,12,31,33) it keeps track of information on specific dates within a 200 year range.
What I'm looking to do is save the array to a file so that I can load it again when the program is started.
In VB 6 I used to be able to use a simple for next loop into an open file and load it the same way. It doesn't seem to work the same way with Fthe filestream class in VB.net

Text File Writer - Saving The File And Refresh The Page
Mar 9, 2009I have an asp page with vb.net code that will query a database and present the user with the number of records that exist that need to be exported along with a button to export them. After you push the export button, it will prompt for a location and filename. But after that, it will not refresh the page with the new counts that now exist. Or in this case update the count to zero for the button they clicked.
[Code]
So how can I tell the page to refresh with the new counts. It almost seems like I need to tell the process to wait until after the user has finished finding the location and saving the file but I don't want to add a generic threading.thread.sleep in, I want it to only wait until they are done and then refresh the page.

Saving String Of Text To File Every Few Seconds
Jun 2, 2009I want to save a string of text to a file every 1.4 seconds or so, and each day at midnight I want to create a new file for the days log data so I keep the file size down. The file stays open the whole time so that it is ready to accept data from several different forms which call a function (SaveToVoltsLogFile(str)), so I open it at module level like this:
Dim fsVlogStream As New FileStream(EVENT_LOG_PATH & VOLTS_LOG_FILENAME & DateString & ".ip", FileMode.Append, FileAccess.Write, FileShare.Read)
Dim swVlogWriter As New StreamWriter(fsVlogStream)
Now each time I call a function SaveToVoltsLogFile(str), the str data gets saved to the file:
Friend Sub SaveToVoltsLogFile(ByVal str As String)
swVlogWriter.WriteLine(str)
swVlogWriter.Flush()
End Sub
But by opening it this way, I cannot call a sub to close it and open a new file for the next day because putting the Dims into a sub means that the file is out of scope to other subs/functions, so my Save... sub won't work! So, what I think I need is a separate sub to open the file, another sub to close it, and another to write the str data. But how do I do this and keep the file in scope to all subs?
