Latest beta not responding if some connections are not available

actnhn

In latest beta LINQPad doesn't respond after launch if there one or more connections that are not available. Stuck at connecting.

JoeAlbahari

I've just uploaded a new beta - let me know if the problem persists.

actnhn

Still same issue

Is there a way to download older beta builds?

Actually it has nothing to do with connections, this time all the connections are available but still after launch LINQPad is frozen.

Unfortunately, this is the same stack trace that you reported previously when calling Dump caused a hang.

I've uploaded a new beta that avoids touching the web browser upon startup, so it should allow you to start LINQPad, but I suspect it will hang when you call Dump.

Can you try running the following query, either on the new beta or release version that works for you:
http://share.linqpad.net/lbmgqx.linq

and let me know the result.

Thanks

The query just stuck on the while loop

while (browser.ReadyState != WebBrowserReadyState.Complete)

Now I am using latest release.

Yes, you're right, calling Dump causes it to freeze.

Is there a way to add some timeout to web browser ready detection?

actnhn

Maybe you can dump WebBrowser control and use

It's pretty neat and we use it on our product as well.

JoeAlbahari

If you remove the while loop where it is stuck, does it still correctly display Test and Test2? And what ReadyState does it report (instead of Complete?)

JoeAlbahari

Also, does it spin on the while loop, or hang when checking ReadySate? And does IE work OK for you on that machine?

actnhn

Even after removing the while loop the query is stuck. When I tried to put a breakpoint to inspect the ReadyState a exception occurred. I reported the error.

IE does work fine on the machine.

Not sure what were the changes in the latest beta but it seems to be working now. KEWL!!!

JoeAlbahari

Hate to say, but I didn't change anything. Does the previous beta still crash, and does the sample with the while loop still hang in the same place?

actnhn

That's strange. The query doesn't hang anymore. I'll test with old beta later. Is there a place where I can download old beta builds?
