I was wondering if you guys can comment on under what circumstances you were seeing the hang?

I am using VAX 1215 on VS.net2003 and frequently hang during debugging sessions as well.. and have just started trying to really determine if it is VAX or something else environmental.

Thanks,
John

We had many reports of a hang in VC++ 6.0. Build 1225 fixed the problem for half the users. Half still have trouble.

You are the first to report of a problem in VS.NET.

Support: Did you notice he said '1215'?

John: Did you mean '1225'?

When you say 'hang', do you mean it hangs and never comes back? Or do you mean it pauses for several seconds, and then continues?

The reason I ask is, we seem to be seeing .NET 2003 doing the latter on a regular basis (while debugging, and while just editing), even the guy that doesn't have any version of VA(X). I need to investigate whether this is a IDE thing...

I mean its gone... for at least several minutes or more before I finally kill visual studio and start over.

Okay, I just had my first hang while debugging. I've never seen it at work, but it just happened at home: I let it run overnight, and it never came back, although it used about 40% of the CPU (apparently) the whole time. The weird thing is, it happened the first time I tried to debug, and I can't reproduce it. I *think* my PC at home has hyperthreading (I quit caring about cutting-edge CPU geegaws about 5 years ago): it's a Dell Dimension 8300, if that helps.

I had it also a few days ago, but wasn't sure if it was VA_X related!

I was debugging, entering a breakpoint but the IDE didn't respond to anything.
My Program was not responding (cause it was sitting at the breakpoint), but the IDE didn't show
the code. Titlebar was disabled (as if it was maximised, but in background) and I wasn't able
to activate it by clicking the mouse.

Had to fire up the TaskManager to kill it...

WinXP, VS .NET 2003, VA_X 1225, no Hyperthreading (although I wish I had one)

This behaviour has not yet occured again... happened only once, not reproducable...

I have seen it both ways... with and without hyper threading (assuming my bios setting actually does turn it on/off).

One more thing I noticed, and previously reported... sometime while debugging, the actual line that I am positioned on is below the horizon of the editor window (notably when I have VS's navigation tool bar and VA's navigation tool bar above the editor)... How do you turn VS's toolbar off?

>> How do you turn VS's toolbar off?

Tools, Options menu item, then 'Text Editor' pane, then 'C/C++' sub-pane, there's a checkbox called 'Navigation Bar'...

It would be handy if you had a stack trace so we can see if it is the same as http://forum.wholetomato.com/forum/topic.asp?TOPIC_ID=2126. I'm currently not seeing this hang during debug and it doesn't hang indefinitely. I do not have hyperthreading, but I am using a multiproc box.

We believe disabling enhanced syntax coloring before debugging prevents hanging. We have one use who has confirmed this. Let us know if the same happens for you.

We have solved the hang-during-debug problem in VC++ 6.0 with assistance from a dedicated customer, Karl Hurst.

Fix will be in the next build, due soon.

I have confirmed, if you have the VisualStudio navigation bar in place, often times, the debug line appears below the horizon, It also appears that this setting is also related to another cursor position problem that I reported earlier (double click in the task list then click in the text window).

We fixed the hang-during-debug problem in build 1228 but broke coloring of non-source windows. Applies to VC++ 6.0 only.

We cannot reproduce this hang problem ourselves. One user has tested numerous builds for us. He is now running fine with build 1228. Build 1229, where we attempt to fixing coloring, reintroduces the hang, albeit not as often.

Let us know if you can reproduce the hang and are willing to install a few debug builds. We have some other ideas we would like to test.

can you provide any clue's? is there some specific sequence of actions that helps to trigger this?

i dont normally use VC6, but i do have it available. if i create a project in VC6, what things should i try to try and get it to hang?

It turns out that it may not even be VA. I uninstalled VA, then reinstalled the ide and platform sdk's, but still I get hangs in one project. I can't blame VA no more, except for the fact that all this comes up after having had VA installed. Wonder if VA is infact completely gone, or if something completely different is now causing the trouble..?

Does VC++ 6.0 generate NCB files for Intellisense/browser info? (Brain is rusty right now.) If so, delete them. The IDE will rebuild them, possibly in non-corrupt forms.

You should have one NCB file for each project.

Yep. VC 6 has ncb files. And, yes, they get corrupted, somehow.

Even tried deleting all VC++ 6.0 generated files, in all projects of my entire source tree, still having hangs. Hangs usually occours on ASSERT statements (MFC application) - the program asserts, bug I never get to see the ide pressing "retry" button. There are no particular 100% processes, or maybe it's the taskmanager not having gui updates. Mouse still moving, but everything's locked - power off needed :-/

Thanks for the tip anyways, I know this is out of your particular scope :)

Now that I think of it. After deleting generated files, I had a few successful asserts. The ncb may corrupt over time, as you point out (well over something like 5 builds...)

Had no hangs since turning off "profiling" for the project - if anyone cares.. :-)

.. and btw, doing this enabled me to "edit and continue" again - missed that a great deal!

I have the same problem (hang during debug in Visual Studio 6).
In version VAX 10.1.1293, after resetting all fonts
(Tools->Format->Reset All) debug works without hanging.
But in version VAX 10.0.1230 it does not help.

Fine!

So what? Why the need to use 1230? Build 1230 is waaaaay outdated...

What is missing in Build 1293 that you tend to keep Build 1230 installed?

Shouldn't we concentrate on removing the issues that keep you from installing/using Build 1293 instead of fixing bugs in an outdated build (which will of course not happen)?
