VC++ .NET 2002: Error C1803 in creation of a simple regular DLL

[Guest]

Hi all,
I used 'Empty Project'/native C++ of the VC++ .NET 2002 to do 'Build' for the SimpleRegular.cpp and SourceFile.h files of the attached code of creation of a simple regular DLL and I got an Error C1083 - can not find or open <stdafx.h>. Is <stdafx.h> already built in the VC++ .NET system? What is wrong in this coding to do 'Build'? Can someone help and point out what is wrong with this coding and how to correct it?
Thanks in advance,
Scott Chang

The file you mention is a file generated by the Project Wizard, so if you
created an Empty Project you won't have it. Just try commenting out the
include.

Hi Scott,

In 2) I meant if you change the line
#include "stadfx.h"
to
// #include "stdafx.h"

it won't try to compile that file, which you don't have anyway. If you've
chosen 'Empty Project' this will be the case.

To create a project that has the stdafx.h file with it, you can go to New
Project -> Win32 Project -> Select DLL and DON'T click 'Empty Project'.

It sounds like the code you're trying to compile has been copy and pasted
from a tutorial or something; see if it's got any clues on the project
configuration they used.

Thanks Steve,
1) Is any Project Wizard in VC++ .NET 2002 for me to do the regular DLL

that needs #include <stdafx> ? I did not see 'Project Wizard' in my VC++
..NET 2002. I tried the 'Managed C++ Project' for the file I had and I got 5
errors (C2504, C2143, C2061, and C2146 twice) and 1 warning (C4183) when I
did 'Build'. Please help and tell me what 'Project Wizard' in VC++ .NET 2002
I can use to do the regular DLL programming.

2) I do not understand what you mean by 'Just try commenting out the

include'. If I tried to use '#include "stdafx.h" in the 'Epmty project' and
did 'Build', I got the same 5 errors and 1 warning mentioned above. Please
give me some detailed instructions to correct this program to get the DLL.
