 Storing large data temporarily Greetings,
I am currently in the development stage of a module which requires access to
USENET.
On bringing back a list of all the available newsgroups on a specified
server, I am finding that I do not have enough room in a standard text box
to hold all of the data, and consequently only the first 100 or so rows are
stored.
When data arrives over (Winsock) the internet, I read it into a string
variable. This string variable also populates a text box on the screen and
writes output to a file.
I know all the groups are coming back - but there is an incrediblely large
amount of them. I can't say to the server "Return 100 groups", "Return next
100 groups" etc.
Can anyone help with this? I need to store all the incoming data in
*something*, a string being the obvious choice, but it just isn't long
enough.
Thankyou in advance for any help you can offer me.

Storing large data temporarily Try the RichTextBox.

Storing large data temporarily The string is only limited by your amount of virtual memory,
but the textbox might stop you...
I guess each "record" is separated by a Linefeed?
You might "Chop off" each ng as it tickles in, and add it to a listview.
Or a RichtextBox, as Michael suggested earlier...

I had no problems reading 15,000+ into a combo box in my "one day
surely be ready" news-reader, so a listbox sounds like the way to go.
Especially if you want to do something with each group without coding
your eyes out.. :)

Excellent, the RichtextBox worked a treat. I'll experiment with the other
controls and let you know what I find.
For the benefit of the USENET archives, I successfully wrote to a
richtextbox a very large string containing data from Microsoft's News
Servers about each newsfroup carried there. This wasn't possible with a
simple textbox, as it cuts off after the first 100? Carriage Returns.

It cuts off after about 32Ks of text actually. That is the limit of
the multiline textbox on Win9x.

Storing large data temporarily Yes, I set up a little project when I saw
your question, and the size of all the Newsgroup-names
available from my news-server amounted to 1.6 Mb of text...
The richtext ctrl handles it w/o problems...

Haven't tested it, but I'm running VS6.0 Service Pack 5 on Windows 2000
