Hey guys...need help again.

I'm trying to use InstallSelectedDriver() to install an HDAUDIO
driver. I use LoadLibrary() and GetProcAddress() to call it. In
fact, I even copied the microsoft example exactly from:
http://support.microsoft.com/kb/889763

InstallSelectedDriver() seems to run, but it crashes the application.
Ironically, I tried the example but I had an InfPath in there that
didn't exist and nothing happened, meaning the app didn't crash. But
of course it also didn't install anything since it was the wrong
driver path. I'm posting the function I call using below, but its
virtually the same as the microsoft example. Please help!

Slight Update. I ran the app on my Dev machine so I could try to see
the error that was causing the crash. It is as follows:

A buffer overrun has occurred in InstallDriverTest.exe which has
corrupted the program's internal state. Press Break to debug the
program or Continue to terminate the program.

For more details please see Help topic 'How to debug Buffer Overrun
Issues'.


How can I track down what is causing the Buffer Overrun?

There is a bug in the sample. Don't pass NULL for the third
parameter. I believe it's something like "LPCWSTR lpszReserved" or
something like that. Just give it a pointer to an empty (but valid/
allocated) buffer. I believe this only happens on Win2k.

I'm encountering this problem on WinXP SP2. Would I passing L"" be
enough, or do I need to pass something else? My C++ is so-so at
best. Any help you can give with examples would be VERY welcome.

Yeah, L"" might work. Why not just try it? Also, have you stepped
through this in the debugger to understand which call is failing?

Also, are you sure you picked your device instance ID, etc. correctly?

Chris,

First off, thank you for your help. I am very greatful. To answer
your questions:

1) I did set through the program. The funny thing is, it doesn't
crash on any function. It crashes once it reaches the end of the
Install() function. Does that make sense? To re-iterate, I have a
main() which creates and instance of the InstallDeviceDriver class and
then calls the Install() function on that class. When the code
reaches the end of the Install() function, it crashes. It never
returns to the main().

2) I'm pretty sure I have the right Device Instance ID. I'm using
CM_Get_Device_ID() to get it. I'm not sure what else I can check. I
assumed that the Device Instance ID and the INFPath are correct
because it does do the install, it just crashes at the end of the
function. It's very frustrating because I can't understand what would
cause the Buffer Overun error that I'm getting. I did try running the
application with the InstallSelectedDriver() call commented out. I do
not get the crash, but of course nothing happens either.

Any more thoughts on this? I'm stuck and I'm not sure where to go
from here. There aren't many help search returns on
InstallSelectedDriver in google.

Yes.

Stack corruption, return address overwritten.

Thanks for your input Maxim. What would cause this and what can I do
about it? Is this a known bug with using InstallSelectedDriver?
