Hello,
I am having a problem with the cl compiler. I have written a C class
(RegConnect.c) which uses Win32 API functions such as RegOpenKey,
RegCloseKey etc. Initially when I was trying to create a dll, using
the cl compiler I was getting many unresolved external errors, Example
1 below (8 in total, 7 to do with the registry function calls and 1
from wsprintfA call) as I hadn't included the AdvAPI32.lib file. So I
created a LINK environment variable and set the value to be
"C:\Program Files\Microsoft SDK\Lib\AdvAPI3 2.lib". When I tried to
generate the dll again I only got 1 link error this time, Example 2,
for wsprintfA. I modified the LINK environment variable, to change the
value to "C:\Program Files\Microsoft SDK\Lib\User32. lib", and re ran
the command, This time I got 7 errors, the 7 registry errors but the
wsprintfA wasn't one of the errors! So I know I need to include both
the User32.lib (for wsprintfA ) and AdvAPI32.lib for the calls to the
Win32 API functions. But if I change the LINK environment variable to
have 2 files, I get LNK2001 error: cannot find file, example 3 below.
1) No LINK environment variable:

I have also tried the newer version of the cl compiler (version 13...)
but it still doesn't work!!!
Is it how I can't have 2 paths in the LINK variable?
Please HELP as this is driving me in sane!!
Thanks in advance!

Mary, C does not specify how the cl compiler works, does not support
classes (that's C++), nor does it include the win32 API. Thus, this
question is off-topic here. There are many Microsoft newsgroups available,
I suggest you find one that deals with win32 and programming.

No, you didn't. There is no such thing as a 'class' in C. Perhaps you
meant the different languagee C++, for which there is a newsgroup
news:comp.lang. c++ but ... (RegConnect.c) which uses Win32 API functions such as RegOpenKey,
RegCloseKey etc. Initially when I was trying to create a dll,
Win32 API functions and DLLs are not part of C++ either. Perhaps you
want a newsgroup, mailing list, or tech support for your implementation
or for Windows. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

If you've ever employed custom error numbers and messages in you programs,
you've probably ended up with code similar to what I've ended up with in
the past something like...

Public Const xyzcErrNumHeyDontDoThat = xyzcErrNumBase + 1
Public Const xyzcErrTxtHeyDontDoThat = "Hey! Don't do that!"

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
