Hi,

I have a simple program that calculates invoices. The actual calculation
happens in a web service (WS in the code).
Since the web service takes some time, I just wanted to put a text in a text
box (resultaat in code) when it started (first line of code) then if ok run
the webservice and when it has finished another message would be put in the
text box.

But only when everything has finished the text box its text changed, so the
first line of code has no effect...

How can I solve this? (code is below)


resultaat.Text = "De facturatie is bezig!"
If ValidatieOK() Then
resultaat.Text = WS.START(Maand.Text, Stelsel.Text)
Else
resultaat.Text = "De facturatie is NIET gebeurd!"
End If
