Re: BeginInvoke freezes

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I assume by your description that you call BeginInvoke on the UI thread. Is
there a reason your doing this? As shown this will "freeze" your UI for any
long running operation like waiting for a network reply so no other events
are processed on UI Q until return or DoEvents(). I would just use a worker
thread and only post back results to the UI after success/failure/progress.

| Hi,
|
| I'm having random problems with BeginInvoke function. I have 2
| WebServices (VB.Net), the first one is the main ws and the second is
| the backup in case that the primary server crash or goes offline.
|
| My client, which is also in VB.Net tries to connect to the first
| webservice and has a timeout of 60 seconds. If it can't connect, it
| tries on the backup. The timeout is 60seconds because I'm using a
| 56kmodem.
|
| The problem is that randomly, the function BeginInvoke, which I use to
| call my WS async will freezes. Sometimes, the primary ws will respond
| correctly, but the backup will crash. Sometimes they both freezes
| BeginInvoke...anyway you see my point. It's very hard to debug
| somethings that is random and all the data my client is sending to the
| ws are valid. The BeginInvoke freezing gets my client GUI to freeze.
|
| Any hints ?
|
| Thanks :)
