Web Browser application randomly getting HTML from server

[nightkids31]

HI guys...i'm developing a application which uses the web browser control in a form to load web pages...but what i need to do is that the application would randomly load HTML's located in one folder of a server...let's say i have 5 HTMLs in a folder and i want the application to randomly load any of those 5 HTMLs located in the folder...any ideas how i can achieve that?... thanks for your time...

You'd need to have a list of the HTML pages located in that folder, but once you have that as, say, an array, you can simply create a Random object and call Next five times to get five random indexes into that array.

i'm sorry but i don't really get you ...could you explain in a little more detail?...
do you think you could post some code for the randomization of html section?...thanks

Here's one method

Dim availableURLs As New Specialized.StringCollection 'Store all available URLs here.
Dim selectedURLs(4) As String 'Select 5 URLs.  Specify different upper bound if required.
Dim indexGenerator As New Random 'Generates random numbers.
Dim randomIndex As Integer 'The next random index selected.
 
For i As Integer = 0 To selectedURLs.Length - 1
    'Generate a random index from zero to the upper bound of the availableURLs collection.
    randomIndex = indexGenerator.Next(0, availableURLs.Count)
 
    'Place the randomly selected URL into the selected array.
    selectedURLs(i) = availableURLs(randomIndex)
 
    'Remove the selected URL from the available list.
    availableURLs.RemoveAt(randomIndex)
Next i

You will still need to populate the availableURLs collection yourself.

Sorry for asking question again..but how do you populate the availableURLs collection?... do i include this code in the AxWebBrowser section?

If you have direct access to the folder then you can use IO.Directory.GetFiles. If you're talking about over the Internet then I'm afraid I don't know.

thanks for your reply though...anyway..what i'm gonna do now is to change the way it works since randomization doesn't work...is there any way that i could load htmls in a folder online sequentially?.. i thought of using a timer so that every 5 seconds the html changes...any ideas how to make it work?..and is it possible to let's say get the application to read the URL address from a text file?...let's say i have a few URL's in a text file and i need the application to load it sequentially?
