MSDN Help

[stormrider]

I was searching through MSDN pages. I've end up here;
http://msdn2.microsoft.com/en-us/library/aa390422.aspx
But when I tried to compile the code given below the page,
I get this error;

c:\program files\microsoft visual studio\vc98\include\comutil.h(101) : fatal error C1001: INTERNAL COMPILER ERROR        (compiler file 'msc1.cpp', line 1786)          Please choose the Technical Support command on the Visual C++
Help menu, or open the Technical Support help file for more informationError executing cl.exe.
dsa.exe - 1 error(s), 0 warning(s)

Any ideas?..
Thanks..

Your build choked on line 101 of the header comutil.h. Something cause the compiler to be uable to parse the line.

It could be bad code preceding this include.
It could be a file with garbage characters in it.

Maybe you couild provide the code around this area.

As I said before, the page I was checking is this:

And the code, which I got the error is this:

Thanks again..

I just compiled and linked your code with no warnings and no errors using Visual Studio.NET 2005 and a Win32 Console Application project.

What compiler and project type are you using??

I'm using Microsoft Visual Studio 6.0 and Win32 Console Application project.

[weaknessforcats]

I'm using Microsoft Visual Studio 6.0 and Win32 Console Application project.

Even with all service packs applied, VC 6.0 is three releases in the past.

A lot of bugs were not backfitted into VC 6.0 but were only carried forward.

Time to get the current version of the compiler.

Thanks for your interest, I'll get it..
