Andrew
The URLs you sent me are for Visual Studio.net. Do you have any links to
the MSVC.

Also I have downloaded the windows debugger and when I am trying to open
.dsw file it says error 2. Any idea on that.

Thanks
Seshu

Hi Seshu,

You shouldn't go open http://msdl.microsoft.com/download/symbols in
browser.

Instead, find, download and install Debugging Tools for Windows from
MSDN.

Then, read and use the following:
1. http://support.microsoft.com/default.aspx?scid=kb;en-us;311503
2. http://support.microsoft.com/default.aspx?scid=kb;en-us;319037
3. http://support.microsoft.com/default.aspx?scid=kb;en-us;823242
4.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/debug/b
ase/using_symsrv.asp

Or, if you have MSVC .NET, you do not even need Debugging Tools for
Windows, as said here:
5.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vsdebug
/html/vxtskusingasymbolserver.asp

Best Regards,

Andrew

It is a COM dll. I Initialize() and CoUninitialize() functions to load
the DLL (If that's correct). Also I read in some discussion boards to
use InitializeEx() than plain initialize as it might not release all the
memory. 


As for the symbols I tried to download them by going to the msdl website
as given below but said unauthorized to download. Is there any way I can
link this up.

I am using MSVC...

Thanks
Seshu

Hi All,

How MTS will figure out how many dllhosts.exe to start. Will it be
dependent on the package or dll or the component got a request from
client? Is there any configuration required to control this.

Regards,
Diwakar

Hi Seshu,

One of the things that could help is having a proper call stack to
understand where it fails. To get the call stack, you need connecting to
MS Symbol Info Server. Modern MS debuggers know how to download debug
symbols for MS system DLLs and generate a proper call stack.

You will need to download and install Debugging Tools for Windows, and
consult its help for configuring path to the symbol server. Usually, it
is an environment variable of a kind:

_NT_SYMBOL_PATH =
srv*c:\symbols*http://msdl.microsoft.com/download/symbols

If you have Visual Studio .NET (either of the versions), this will be
enough to get a very nice call stack with all system functions. I'm not
sure if VB knows to generate it, but VC++ does know for sure. Or you can
debug from WinDBG, which is more complex and unfriendly, but often
provide more useful info on the crash.

Best Regards,

Andrew

Hello All

I am in a rather complex condition. I have a deadline to meet on Monday.
So please please help me.

Here is the situation: I have an application (VB app) talking to a DLL.
When I put the dll in debug mode and carry out some functions, I am
seeing exception in ntdll.dll and the call stack just shows a memory
location. I am unable to decipher this. Can anyone please tell me how to
exactly pinpoint where the problem is - I had  seen in some discussion
boards that this is because of loose hanging pointers....

Had anyone seen this?

Thanks
Seshu
