Access violation reading location 0xbaadf00d: Microsoft Visual Studio is busy

Hi,

Since 2 days I have some mostly anoying problem with my application when
debugging:

My application sometims freezes, and I get this balloon:
"Microsoft Visual Studio is busy"

And than the unhandled exception:
"First-chance exception at 0x79e9be2b in MyApplication.exe: 0xC0000005:
Access violation reading location 0xbaadf00d."

And in the output window also:
"The program '[3152] MyApplication.exe: Managed' has exited with code
1073807364 (0x40010004).
The program '[3152] MyApplication.exe: Native' has exited with code 0
(0x0)."

I don't think finding a solution now will be possible, but what bugs me is
the fact that I don't know why and where this happens? I don't have any clue
in which project/file/method this problem happens.

Is there a way to see more information when such a thing happens?

Thanks a lot in advance,

Pieter

This is probably a fairly serious problem, and perhaps nothing to do with
your code. Unless you did it intentially in a C++ program, 0xbaadf00d almost
certainly means an uninitalized pointer down in native code somewhere. Are
you using any third party libraries? I'd certainly start to lean towards
other people's code in this case(its one of the rare ones, managed code
should not generate that error)

As to how to try to figure out roughly where it happens, the best option I
know if is tracing. If you have your app spit out trace lines in every major
method you can figure out roughtly where the issue occured, atleast if it is
in your code. I don't think much else can be done though.
 
Hi,

Thanks for the answer.
I didn't use any third party libraries, but I did integrate this article
(http://msdn.microsoft.com/library/d...y/en-us/dnwinforms/html/dragdrop_datagrid.asp
for moveing column-headers) in my DataGrid, and I'm almost sure it started
after this. It contains some funky methods like BitBlt Lib "gdi32.dll",
GetWindowDC Lib "user32.dll", ReleaseDC Lib "user32.dll".

But because of the fact that I got this problem on moments that had nothing
to do with this code, I didn't really suspected it. I also got it this
weekend with a whole new test project, that didn't contain anything of it:
just a simple form to test something, and during debugging it freezed also
and I got also the "Microsoft Visual Studio is busy"...

I don't think it's due to my pc? It's a freshly installed laptop (less than
1 month), with AMD DualCore +4400 proessor, 2 giga RAM, .. it should be
enough... :-)

I'll try with tracing, but I'm affraid it won't help me a lot.

Thanks,

Pieter

Your machine is probably fine. At this point I'd guess an IDE problem. Try
reinstalling visual studio maybe?
 
I get this "Microsoft Visual Studio is busy" message constantly.
Sometimes if I just Step Over a line, it won't advance to the next
line. Clicking around the source code will cause the balloon to popup
over the task tray. It will also say something about visual studio is
waiting to complete an internal operation and to contact Microsoft if
it happens repeatedly. I usually have to close down the application by
right clicking in the task bar because nothing in VS2005 works any
longer. Then I'll get an error message about debugging something for
which it has no source code for ("There is no source code available for
the current location." and buttons to 'OK' or "Show Disassembly"), and
then I'm back in the debugger as if nothing happened. Happens several
times a day. Very annoying. I think it has something to do with some
COM, OCX, or ActiveX controls that I've included in the project but
it's so random that it's hard to replicate.
 
Exactly what happens with me :-(

I did a system restore yesterday to a some days before I started to get this
problem, and untill now everything goes right...
 
The system restore didn't work :-( I have it less times now, but I still
have it :-(
