Asynchronous calls and events

Can you supply a sample application which uses asynchronous calls (i.e. VerifyKeyAsync) and events (i.e. VerifyKeyCompleted)?</o>
</o>
Thanks</o>

 

Try this Google ASP.NET CoOp, pulled up a bunch of examples:


http://www.google.com/custom?hl=en&amp;lr=&amp;client=google-coop&amp;cof=CX%3AGoogle%2520Wise%3B&amp;q=asp.net+asynchronous+calls&amp;cx=009244845836111659857%3Albvxsjj8mho

 

Finally figured out how to make the events fire.
</o>
1. Declare the api.
</o>
public wrDiscountaspi.CustomerApi customerApi = new wrDiscountaspi.CustomerApi();</o>
</o>
2. </o>Create an event handler routine.</o>
</o>
public void myVerifyKeyCompleted(object sender, wrDiscountaspi.VerifyKeyCompletedEventArgs e)</o>
{</o>
bool bResult = e.Result;</o>
bool bCancelled = e.Cancelled;</o>
</o>
// do something</o>
}
</o>
3. Register for the event
</o>
this.customerApi.VerifyKeyCompleted += new DiscountASPNet.wrDiscountaspi.VerifyKeyCompletedEventHandler(myVerifyKeyCompleted);</o>
</o></o>
4. Make the asynchronous call to validate the key.
</o>
customerApi.VerifyKeyAsync(sKey);
</o>
