Subject says it all. Has only happened to me once and has happened to my coworker twice since we've installed 1239. My coworker doesn't have any other plugins installed, so this it can't be a plugin conflict.
Also, it is hard to reproduce. Seems to be completely random. But when it happens, it just sits there. msdev.exe CPU usage is 0%, so it's not spinning.
I'm baffled. |

We have not experienced the problem.
Do you have multiple CPUs?
Try to get a call stack for us. |

My coworker and I both have just 1 CPU. As I said above, it is completely random and I haven't seen it for a while, so it may be a long time before I can get a call stack for you.
I was hoping more people who use Visual Studio 6 would have seen this and maybe they would think to get a call stack for you. The more people aware of this the better the odds of catching it in the act. Very elusive. |

| I am also seeing this once in a while. I am using VC6/SP5 on a single processor machine and have normally two instances of MSDEV loaded. If it happens it is always while opening a new workspace. |

| I've actually seen this same behavior when using VS6/SP5 during the registering component phase of the build. It's just like the process never returns. I kill the IDE and reload the project to find everything built and linked, and the component has even been registered. As stated above, no rhyme or reason to what causes this to happen, might happen 2 builds in a row, or might not happen for days. I have an Intel HT processor so XP sees it as 2 processors. |

I also had a similar problem when switching projects.
Usually happens after I already switched projects several times.
I also tend to work with two instances of MSDEV open, so it may be related. Not sure if it ever happened with only once instance.
However, waiting long enough (about 10 min in a very rough estimate), the project loading suddenly resumes and completes successfully.
Once that happened, though, future project loading/switching will almost always have the same problem, so I just close the IDE and re-open it.
Not sure if it started with 1239, might have been there with 1237 as well, I don't recall.

| I just had it happen again. I ran a second instance of DevStudio so I could do an "Attach to process..." on it, but when I did, a message box popped up and said "User break point called at ..." (don't remember the address), I clicked the OK button and frozen instance was shutdown. How are you supposed to get a call stack if you can't attach to it? |

Does the hang occur when switching projects prior to completion of our parsing?
If we understand the problem correctly, the IDE should recover after two minutes.

If you mean prior to parsing from the project that is being switched out of, then no. This happened with projects that are active for some time, when the file in focus has been active for a time.
If you mean if the hang happens sometime during parsing, then it's possible, but I'm not sure. When loading a project there is a progress bar to show the loading stage. Usually the VA parsing status is written to the statusbar only after the loading has finished the the progress bar is removed.
The hang occurs while the progress bar is still there, even though near the end. So it's certainly before VA parsing is over, but I'm not sure if it's during, or if it's just before.
The IDE recovers, but whenever I tried waiting it took more than two minutes. I don't have that great a CPU, though, and if I wait then I do something else in the meantime instead of keeping the locked IDE in the foreground, so it may affect the timing. |

The last time I saw this I was in the project for a good while, so parsing was finished. When I had completed my changes in that project, I switched to another project and it locked. I waited several minutes and it never recovered. The CPU is idle and no memory usage changes are happening when in this state (according to Windows Task Manager). I also had it lock on shutdown with the same behavior. Sounds like it is more about cleaning up after a project is closed than initialization when a project is opened.
I think Yaron is talking about something other. |

A good tool to help identifying locks like this is the Process Explorer from www.sysinternals.com - it can display all locks, mutex, semaphores, etc. and their state of any application. Its free and a must-have for any serious programmer, except if you wrote a tool like this your own

I have encountered the problems mentioned above with more than one instance of MSDEV open (Visual Studio 6 SP 6).
In addition, sometimes the IDE does not freeze/deadlock, but paints a source code window symbol after symbol with noticeable delay (> 50 ms per symbol).
Regards,
Kirill |

| I was able to get it to lock by running a second copy of VC6, loaded a project in it, then exited the second copy. I went into the first copy and switched projects. It locked, so I ran Process Explorer that Uniwares suggested. Saw that things (context switches) were still happening, even though the CPU usage never left 0%. So I waited for a few minutes longer and then VC woke up and finished the load of the project. But, now every project switch is lagging bigtime (several minutes). This is easy to reproduce. Try it and you will see. |

I have similar problem but it does not finish with hang. I just need to wait couple of seconds (more that 30 actually) and I get IDE responding again. I have a project that always behaves like this when loading and very often when browsing classes (expanding class tree).
I am fully sure it was present starting from VA6 (build 1106 I guess) and all the builds of VAX I had a chance to have including 1239).
Building project from scratch does not help, so it looks like there is something in code that spoils VAX loading.

ether, i have tried your steps on VS .NET 2002 and it doesn't lock up. this doesn't prove much, but i don't have VC6 installed to try *shrug*
as for support, there are lots of threads where they never post. i suspect we are proving a bit much for them to keep up with  |

This is still happening in 1278 with VS 6. It is becoming very annoying. I'm afraid that if you don't fix it I will have to uninstall it and I will not be able to recomend this software to any new developers I come in contact with.
Why can't you get this to happen??? All you have to do is work in a project for a while, switch to another project for a while, then switch again. That is the shortest sequence of events that I can come up with. It will not do it if you just sit there in the project. You must do work. |

I hope you are just trying to be a smart ass.
What I meant by "You must do work" is that you have to do edits and possibly compiles. Just opening a project and then switching to another doesn't seem to cause the problem, unless it is time related - meaning if you want to try to reproduce it without editing, let VS 6 sit in the project with a few files open for a half hour or so.
The lock also happens when just closing the current project, so it's not opening a new one that is the problem. |

i have installed VC6 on a virtual machine, for testing purposes, but i don't do any development using it. when i develop at home, i use the Qt library, which is a 500meg install, plus you need to set up the projects to use it.
as a result actually working properly with VC6 isn't that easy for me, but i can run basic tests, which is normally sufficient.
if you are simply looking to try and reproduce a bug someone else has posted while at work, you can run basic tests, but more complex tests, like you have found are required, may not be an option. i appreciate having the IDE lock up is very frustrating, but sometimes these things are very hard to reproduce. |

We are still trying to reproduce the problem. No luck yet.
We are walking through code to see if we can spot the problem. No luck yet.
We will continue... |

Can you enable logging on our Performance tab just after you start the IDE? Reproduce the problem. Exit the IDE as best you can. Zip and send us c:\\va.log |

At first look through your log, it appears VA X and the IDE are just generally slow. We see nothing glaring, though we will continue to look.
Watch for external factors that might affect performance, and post other clues if you find them. |

| It is slow when loading some of our workspaces, especially the one with 30+ projects in it. That isn't the issue because it always recovers from the load. Task manager shows the processor pegged in that situation. The issue is with the closing of the current project. That is where it locks and task manager shows 0% usage by msdev.exe. This was the case when I zipped up the log file and emailed it to you. |
