How to update listview ONLY when new data is avilable?

Hope this clears it up… make the code from your post above part of a function or sub called refreshlistview… then in another sub use something like:

Dim objDocCopy As MSXML2.DOMDocument

private sub XMLCompair()

Dim objDoc As MSXML2.DOMDocument



'load the xml document

Set objDoc = New MSXML2.DOMDocument

objDoc.async = False

objDoc.Load "http://localhost/xmloutput.php"



'compair files

if objDoc  objDocCopy then

objDocCopy = objDoc

refreshlistview()

end if

end sub

you only want to process the xml if it has changed… so you want to load the web page, check if it has changed, and if it has, make a copy of it and then refresh the listview.

“http://localhost/xmloutput.php”

In Onload event i prepare listview1 and i start the timer and from inside timer i call populatelistview that holds my code. populatelistview reload listview .

Instead of calling populatelistview from your timer, call XMLCompair from my previous post and from XMLCompair call populatelistview (instead of refreshlistview) if the 2 xml files are different.

So where should i use your code?what should be inside refreshlistview() ?

You never mentioned timer? how then i do the check regulerly?

i never mentioned how to use the timer because i thought you would be able to figure out how to put it together on your own.

furthermore,shouldn’t this line:
Dim objDocCopy As MSXML2.DOMDocument be outside compair function?

if you look back up at my post, it is outside the sub @autopilot wrote:

Dim objDocCopy As MSXML2.DOMDocument

private sub XMLCompair() 

just a note… you may need to dim as new

Dim objDocCopy As New MSXML2.DOMDocument

as far as you getting an error, i am not sure what to tell you… i have never used vb6… i did basic programming a long time ago (15 yrs or more) and just in the last 2 yrs i have started programming with vb 2005… so i dont know what else to tell you…

but i will look at compairing xml files with vb 2005 and see what i can come up with… but the should work (i never tested it though)
