read data from web page 1

[dan]

I am looking for an easy way to have a VB program look to a text file on the web to compare versions and prompt to update if a newer version is available. I don't want to display the contents of the text file, but only read them into a variable to compare with the current version.

Fetching the data is trivial, and there are umpteen ways to do it including the built in AsyncRead method. Then you'll have to parse your data and check versions, etc. - also a trivial matter but dependent on your data format and how you store the current version.

Is there a question here? Perhaps one not already answered many times?

I am not familiar with the AsyncRead method. What syntax would I use to read the text of abc.com/ver.htm into a variable?

The syntax is detailed in the VB6 documentation. However, here is a trivial example using a UserControl:

[blue]Option Explicit

Private Sub UserControl_Click()
    UserControl.AsyncRead "ftp://ftp.microsoft.com/MISC/disclaim.txt", vbAsyncTypeByteArray 
End Sub

Private Sub UserControl_AsyncReadComplete(AsyncProp As AsyncProperty)
    Debug.Print StrConv(AsyncProp.Value, vbUnicode)
End Sub[/blue]

First you asked about a text file, now you say .htm which suggests you haven't thought this through.

Plain text is far easier to deal with for something like this.

I did find simple way to accomplish this task:
I installed the Microsoft internet transfer control
txtNewVer = Inet1.OpenURL("

http://www.mywebsite.com/ver.txt",

icString)

Thank you for your suggestions.

Nothing like picking the oldest, cruddiest, more problematic option I guess.
